Annual research review: A meta-analysis of the worldwide prevalence of mental disorders in children and adolescents.

Has the Prevalence of Child and Adolescent Mental Disorders in Australia Changed Between 1998 and 2013 to 2014?

Children younger than 7years can develop mental disorders that might manifest differently than in older children or adolescents. However, little is known about the prevalence of mental disorders at this early age. We systematically searched the literature in the databases Web of Science, PsycINFO, PSYNDEX, MEDLINE, and Embase to identify epidemiological studies of community samples published between 2006 and 2020. A series of meta-analyses was conducted to estimate the pooled worldwide prevalence of mental disorders in general, specific mental disorders, and comorbidity in young children. A total of ten epidemiological studies reporting data on N=18,282 children (12-83months old) from eight countries met the inclusion criteria. The pooled prevalence of mental disorders in general was 20.1%, 95% CI [15.7, 25.4]. Most common disorders were oppositional defiant disorder (4.9%, 95% CI [2.5, 9.5]) and attention-deficit hyperactivity disorder (4.3%, 95% CI [2.5, 7.2]). The prevalence of any anxiety disorders was 8.5%, 95% CI [5.2, 13.5], and of any depressive disorders was 1.1%, 95% CI [0.8, 1.6]. Comorbidity was estimated at 6.4%, 95% CI [1.3, 54.0]. The literature search reveals that the epidemiology of mental disorders in children younger than 7years is still a neglected area of research. The findings also indicate that there are a significant number of young children suffering from mental disorders who need appropriate age-adapted treatment.

BackgroundChildren and adolescents are more vulnerable to the affects of war and violence than adults. At the time of initiation of this study, nothing was known about the prevalence of childhood and early adolescence mental disorders. The aim of the present study is to measure the point prevalence of mental disorders among children of 1–15 years age in the city of Mosul, Iraq.MethodsA cross-sectional study design was adopted. Four primary health care centers were chosen consecutively as a study setting. The subjects of the present study were mothers who came to the primary health care center for vaccination of their children. The chosen mothers were included by systematic sampling randomization. All children (aged 1–15) that each mother had were considered in the interview and examination.ResultsOut of 3079 children assessed, 1152 have childhood mental disorders, giving a point prevalence of 37.4%, with a male to female ratio of to 1.22:1. The top 10 disorders among the examined children are post-traumatic stress disorder (10.5%), enuresis (6%), separation anxiety disorder (4.3%), specific phobia (3.3%) stuttering and refusal to attend school (3.2% each), learning and conduct disorders (2.5% each), stereotypic movement (2.3%) and feeding disorder in infancy or early childhood (2.0%). Overall, the highest prevalence of mental disorders was among children 10–15 years old (49.2%) while the lowest was among 1–5 year olds (29.1%). Boys are more affected than girls (40.2% and 33.2%, respectively).ConclusionChildhood mental disorders are a common condition highly prevalent amongst the children and early adolescents in Mosul. Data from the present study mirrors the size of the problem in local community. Several points deserve attention, the most important of which include giving care at the community level, educating the public on mental health, involving communities and families, monitoring community mental health indicators, and providing treatment at primary health care level.

Background：There has been a lack of prevalence estimates of DSM-5 mental disorders in child populations at the national level worldwide. Little is known about the disease burden of child mental disorders. Taiwan’s National Epidemiological Study of Child Mental Disorders (TNESCMD) was designed to address these research gap. This study reported the methodology of the TNESCMD and the lifetime and six-month prevalence of mental disorders according to the DSM-5 diagnostic criteria in Taiwanese children. I further compared the prevalence and estimated disease burden from the TNESCMD with Taiwan National Health Insurance Research Database (TNHIRD). Methods: The TNESCMD used stratified cluster sampling to select 69 schools in Taiwan resulting in a nationally representative sample. Among all 10118 eligible children selected via our sampling method, 9560 (94.4%) children, 6846 (67.6%) parents, and 9759 (96.3%) teachers participated in this study and completed the questionnaires. Among them, 4816 children in grades 3 (n=1352), 5 (n=1297), and 7 (n=2167) further underwent face-to-face psychiatric interviews using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Epidemiological (K-SADS-E) version, modified for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Clinical questionnaires for attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), emotional and behavioral problems included the Chinese version of the Swanson, Nolan, and Pelham IV scale, Social Responsiveness Scale, and Child Behavior Checklist were used to examine the convergent and divergent validity with K-SADS-E. Risk factor analysis for mental disorders included sex, age, urban/rural and community income. 1,389,372 participants aged 8 to 14 were randomly selected from the 2016 TNHIRD claims dataset. The disease burden was calculated regarding years lived with disability (YLDs) with adjustment for comorbidity. YLDs and their 95% uncertainty intervals (UI) were reported. A rates ratio (RR) was reported to depict the strength of YLDs difference between TNESCMD and TNHIRD. Results: The K-SADS-E showed satisfactory inter-rater reliability (prevalence adjusted bias adjusted kappa = .80-1.00) among eight interviewers. The diagnoses of K-SADS-E demonstrated good convergent and divergent validity with most corresponding clinical questionnaires. The weighted lifetime and 6-month prevalence rates for overall mental disorders were 32.3% and 25.8%, respectively. The most prevalent mental disorders (lifetime, 6-month) were anxiety disorders (15.1%, 13.5%) and ADHD (10.5%, 9.0%), followed by sleep disorders, tic disorder, oppositional defiant disorder, and ASD. New DSM-5 mental disorders, avoidant/restrictive food intake disorder and disruptive mood dysregulation disorder, were also found with current low prevalence (<1%). Boys were more likely to have neurodevelopmental disorders and disruptive and impulse-control, and conduct disorders, whereas girls were more likely to develop anxiety disorders, depressive disorder and anorexia nervosa. Depressive disorder and suicide-related problems were more prevalent in Grade 7 children. The participants living in urban areas and low socioeconomic communities had increased risks for mental disorders. The overall YLD from all mental disorders in the TNESCMD was 5.24 times (95% UI: 4.15-6.70) more than that in TNHIRD, with the lowest and highest YLDs RR for autism spectrum disorder (ASD; RR: 2.24 and 95% UI: 1.28-3.93) and anxiety disorders (RR: 351.00 and 95% UI: 175.05-703.80), respectively. Unlike ADHD and ASD, the total proportions explained by anxiety disorders and conduct disorder/oppositional defiant disorder were significantly lower in TNHIRD than those in the TNESCMD and Global Burden of Disease 2016. Conclusions: Our findings suggest that the Mandarin version of the K-SADS-E for DSM-5 is a reliable and valid instrument for diagnosing child and adolescent mental disorders based on DSM-5. Similar to the DSM-IV prevalence rates reported in Western countries, indicate that DSM-5 mental disorders are common in the Taiwanese child population. The comparatively higher estimate of the disease burden of mental disorders in children from community-based setting might provide the preparation of future financial resource allocation, development and management of medical service, and human resource for mental health care in the clinic-based settings. For disorders with a significant difference in disease burden between the community-based and clinic-based settings, they may need more mental health promotion and prevention.

As in many other countries, child psychiatry in China has gradually developed from general psychiatry. In the early days of the profession, child psychiatry was considered as psychiatry for "little adults". Child psychiatry in China has gradually developed and expanded since the implementation of Professor Guotai Tao's child psychiatric services in Nanjing in the 1930s. In particular, the profession has developed rapidly since its affiliation with the International Association for Child and Adolescent Psychiatry and Allied Professions (IACAPAP) in 1998. Child psychiatry has been one of the fastest developing advanced international disciplines over the past 10 years. Pediatric psychiatry mainly focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. In 1899, the term ''child psychiatry'' (in French) was used as a subtitle in Manheimer 's monograph Les Troubles Mentaux de l'Enfance. The Swiss psychiatrist Moritz Tramer (1882–1963) was probably the first to define child psychiatry, in 1933, in terms of diagnosis, treatment, and prognosis within the medical discipline. In 1934, he founded the Journal of Child Psychiatry (1934–1952), which later became Acta Paedopsychiatrica (1953–1994). The first academic pediatric psychiatry department was established in 1930 at the Johns Hopkins Hospital in Baltimore by Leo Kanner (1894–1981). Since then, the clinical practice, research, and teaching of child psychiatry have gradually developed around the world.1 There have been three stages to the development of children's psychiatry in China. The first is the exploration and development period, which occurred mainly during the 1930s to the 1950s. This period was characterized by the introduction of Western models by experts and the exploratory development of child psychiatric services. Professor Yulin Cheng, Guotai Tao, and Yonghe Ling other professors are the pioneers. The second stage is the initial development period, which occurred from the 1950s to the late 1970s. Child psychiatric clinics and/or wards were established in Nanjing, Shanghai, Beijing, Guangzhou, Sichuan, Hunan and other places and child psychiatric teams were formed. Although there was a pause in the early 1970s, child psychiatric service models continued to be developed. The third period, from the late 1970s to the present, was characterized by rapid progress. The development of child psychiatry has been promoted mainly since the economic reform and opening-up in China, with the transformation of the medical model from a pure biomedical model to a biopsychosocial medical model. Psychiatrists, pediatricians, and psychologists have begun to focus on child mental health and have conducted some interdisciplinary research and practice. Following the establishment of the Nanjing Child Mental Health Research Center, many provinces and cities have established child mental health centers. Psychiatric hospitals or mental health institutes affiliated to major medical universities in Nanjing, Beijing, Hunan, Sichuan, Shanghai and other places have successively established Master's and doctoral training sites for child psychiatry and applied psychology. Relevant disciplines and research institutions such as child health care, behavioral pediatrics, special education schools, and autism training centers have successively joined the ranks of child mental health services. In particular, Professor Guotai Tao founded the Nanjing Child Mental Health Research Center in 1984. In August 1987, the center was appointed by the World Health Organization (WHO) as a scientific research and training cooperation center, and was appointed by the Chinese Ministry of Health (now the National Health Commission) as a child mental health guidance center. Many child psychiatrists and mental health workers have been trained, and academic exchanges have been promoted in China and abroad.2 With the rapid development of disciplines, Chinese child psychiatry has reached an internationally renowned and advanced level. Multidisciplinary participation in child psychiatry is good. For example, the psychology of child development, developmental behavior pediatrics, child neurology, child health care, education, and sociology have begun to attach importance to clinical practice and research on mental health. A growing number of universities and colleges offer degrees for social workers in clinical psychology and childcare. In addition, with more primary care centers in the community, primary care physicians can implement screening and follow-up for children with mental health disorders. However, the primary care providers still need more education and training. To address this problem, the National Health Commission has been advocating multilevel collaboration. Pediatricians and primary care physicians across the country are now being trained in early diagnosis and basic treatment for common mental disorders in children. They are taught to screen patients for signs of developmental disorders by checking, for example, whether a 3-month-old baby's eyes can follow moving objects or whether an 18-month-old child can make eye contact. The problem of the shortage of child psychiatrists has been partially solved.3 Children and adolescent mental health problems are related to a country's development and to global changes. About 20% of children and adolescents worldwide experience mental health disorders. The major challenges for children and adolescents with mental disorders are stigma, isolation, discrimination, and the lack of access to health care and education facilities. Obviously, children and adolescents are vulnerable groups; they have no political power and their mental health problems are complicated. The mental health of children and adolescents requires multisectoral cooperation and the attention of the whole society. In particular, the protection afforded by government actions and policies is crucial. Policies must be designed to ensure that children and adolescents can access even the most basic mental healthcare. However, there are few countries worldwide that provide specific policies for the mental health needs of children and adolescents.4 China has a large population of children. Rapid economic development and social reforms in recent years have had a substantial impact on the mental health of children and adolescents. Increasing social pressures and workers migration, and changes in family planning, have changed traditional family structures and social support systems.3 As part of development and progress within China, the Chinese government has initiated a series of policies and regulations to promote mental health. Some of these policies are aimed at promoting mental health in children and adolescents; for example, "The Law of the People's Republic of China on the Protection of Minors", "The Law of the People's Republic of China on the Protection of the Rights and Interests of Women and Children", "The Law of the People's Republic of China on the Protection of Disabled Persons", "Mental Health Law of the People's Republic of China", and programmatic documents such as the "Healthy China 2030 Planning Outline", "National Program of Outline for Action for Child Development in China (2011–2020)", "Guidelines for the Prevention and Treatment of Attention-Deficit/Hyperactivity Disorder'', ''Guidelines for the Diagnosis, Treatment and Rehabilitation of Children with Autism'', and ''Technical Specifications for Children's Mental Health Care''.5-10 These reflect how the support of national policies has driven the development of child psychiatry. Major national basic and clinical research projects have invested in child psychiatry research, such as the National Natural Science Foundation of China, which has supported national research and development plans in key health areas. Research by a team led by Professor Zhang Dai has demonstrated that FMR1, DISC1, EN2, and SHANK3 genes are related to autism. Studies by a team led by Professor Kun Xia and Jingping Zhao have shown that XRXN1, GRIN2B, RELN, and DAB1 genes may be antecedents of autism. Such research has been published in several high quality academic journals in recent years.11, 12 Some research of the National "12th and 13th Five-Year Plan" scientific and technological support projects led by Professor Yi Zheng, on "The Epidemiological Study of Child Mental Disorders in China" and "Comprehensive Intervention Strategies for Chronic Non-communicable Diseases with Attention Deficit-Hyperactivity Disorder". These show that Chinese child psychiatry has become a discipline supported by the national key research project. Traditional research group in child psychiatry include the team led by Professor Guotai Tao, Jie Lin and Xiaoyan Ke about autism, mental retardation and childhood schizophrenia; team led by Professor Yufeng Wang on attention deficit hyperactivity disorder; team led by Professor Xiaoling Yang and Jing Liu about autism spectrum disorders; team led by Professor Xuerong Li, Linyan Su and Xuerong Luo on epidemiological surveys and tool scales for child mental disorders; team led by Professor Rene Xin, Yasong Du and Wenhong Chen on epidemiological investigation of children's behavior problems and related research on child psychology and family therapy; team led by Professor Shiji Zhang, Yi Zheng, Yonghua Cui and Fan He on tics and related disorders; and team led by Professor Youhe Shan, Lanting Guo and Yi Huang on behavioral scales and tic disorders. The above studies have published valuable articles in academic journals and won many awards. Child psychiatrists need to be dedicated. The treatment of patients with mental illness is difficult and often daunting, and children's mental health disorders are particularly difficult to treat. Treatment of children with autism or mania requires tackling difficult problems and good practice in basic clinical skills. In China, child psychiatrists experience low returns and low income. The number of child psychiatric inpatients and outpatients is constantly increasing, and their treatment often relies on the dedication of child psychiatrists. To treat such patients, there are now more than 10 centers, nearly 1000 beds, and dozens of special education centers, such as autism rehabilitation centers. To care for left-behind children, children infected with AIDS, children affected by natural disasters such as earthquakes, and children with substance abuse and internet addiction, many child mental health workers and full-time child psychiatrists have formed competent national and local emergency response teams. Child psychiatrists are now available to help children to cope with a variety of social disasters, such as the Wenchuan earthquake or the "3.01" terrorist incident in Kunming. The development of modern child psychiatry in China is interlinked with foreign exchange. Since Professor Guotai Tao's studies in the United States in 1940, Chinese child psychiatry has been continuously introducing and incorporating foreign advanced diagnosis and treatment and research concepts. At present, Professor Tao has discussed diagnostic issues with international authoritative experts in foreign journals and participated in the preparation of the 11th revision of the International Classification of Diseases (ICD-11). Professor Tao was the first international participant in efforts to promote the integration of child and adult psychiatry and the popularization of the notion of the lifelong effects of mental illness, such as the Cross-Strait Summit Forum, and domestic and foreign academic institutions and academic exchanges, such as the Asian Society for Child and Adolescent Psychiatry and Allied Professions (ASCAPAP) and the International Association for Child and Adolescent Psychiatry and Allied Professions (IACAPAP). Chinese child psychiatrists have attended and contributed to both of the latter societies. Since the 1930s, older generations of individuals, such as Yulin Cheng, Guotai Tao, and Xueshi Chen, have made substantial contributions to the development of the discipline of child psychiatry. In 1989, Professor Jie Lin set up and led the Child Psychiatric Group of the Chinese Medical Association Psychiatry Branch. Professor Guotai Tao served as a consultant of the Group. Almost at the same time, the Chinese Mental Health Association established the Child and Adolescent Professional Committee, with Xuerong Li as director. Xueshi Chen serves as a consultant. Since then, two academic organizations have held annual meetings or training courses. In 1998, Professor Shiji Zhang, Yi Zheng, and Linyan Su participated in the IACAPAP congress and joined this organization, which is the most highly regarded academic organization in international child psychiatry. Chinese child psychiatry is fully in line with international developments in child psychiatry. In 2003, Professor Yi Zheng and Linyan Su attended the WHO Expert Headquarters "Concern for Children and Adolescents with Mental Disorders" meeting as Chinese representatives. In the same year, Professor Yi Zheng participated in the ASCAPAP congress and was elected as an executive member. In 2004, Professor Yi Zheng was appointed onto the IACAPAP executive committee. Professor Yi Zheng created the Cross-Strait Children's Psychiatry Summit Forum, which is held once every 2 years alternately in the mainland of China and Taiwan province, China. The Forum is now in its ninth session and has promoted the rapid development of the discipline. In 2010, the 19th IACAPAP International congress was successfully held in Beijing. This was the first time that this congress had been held in a developing country. Professor Yi Zheng served as Executive Chairman, and Professor Jing Liu served as Chairman of the organizing committee. Xiulian Gu, Zhu Chen, Wenkang Zhang and the country's main health care officials attended the opening ceremony and delivered speeches. More than 1300 foreign scholars and 500 domestic scholars attended the congress. Yi Zheng was elected onto the ASCAPAP executive committee and was elected Chairman, and Jing Liu was elected Vice-Chairman of ASCAPAP. At the 21st IACAPAP Conference held in South Africa in 2014, Professor Yi Zheng was elected Vice-President of IACAPAP and won the International Child Psychiatry Outstanding Contribution Award, indicating that Chinese child psychiatry has played a major role on the international stage.2 China has a population of more than 1.3 billion individuals, of which 238 million are children younger than 15 years of age.13 Though a nationwide prevalence study is lacking, some regional epidemiological studies show that the prevalence of mental health disorders in children is close to the worldwide prevalence of 20%,14-18 indicating that about 50 million children in China require treatment for mental health disorders. However, there is a scarcity of child and adolescent psychiatrists (CAPs) in China, and there are less than 500 full-time CAPs nationwide. Currently, only a national psychiatrist certification system exists, and there is no child psychiatrist certification system. Instead, students must obtain a postgraduate training certificate or a nationally approved Ph.D. or Master 's degree training certificate to become a child psychiatrist. A recent survey showed that training units for CAPs are mainly concentrated in large and medium-sized cities. Moreover, only a small number of medical personnel in China can diagnose and treat children and adolescents with mental health disorders, and these have insufficient training. Currently available training for child psychiatrists contains insufficient scientific, practical, and problem-solving content. Furthermore, current educational training poorly equips child psychiatrists for subsequent teaching and professional scientific research abilities. Therefore, a greater training focus is needed on more comprehensive qualities and abilities, such as dedication. Although CAPs undertake a long process of training, this mainly comprises postgraduate or doctoral Master's degree training; the national specialized certification system for CAPs has only been piloted in major cities. The CAP training system requires further improvements, and more CAPs are needed.19 China still has a shortage of child psychiatrists. To address this, a new type of multilevel collaboration is currently being implemented. Pediatricians and primary care physicians are also receiving training in child psychiatry. In addition, psychotherapists from other countries have been recruited to help train psychiatrists. China is currently exploring all possible ways to strengthen multilevel collaboration to promote the children's physical and mental health.3 The artificial boundary between children and adults with mental health disorders will be removed: more attention and value will be placed upon the treatment of adult attention deficit–hyperactivity disorder (ADHD), adult autism spectrum disorder (ASD), adult tic disorder, and other issues. Gene diagnosis and classification of child neurological and mental development disorders will become a reality: the detection of genes for susceptibility to ASD, ADHD, tic disorders, child schizophrenia, and child bipolar disorder will become possible. The concept of the supremacy of child mental health will gradually be accepted. More and more studies have confirmed that among the main factors for healthy and successful child developmental, child mental health is of paramount importance. As physical health and nutritional issues have been generally resolved in most parts of China, the impact of mental health on the future success of children will be a core health issue. Therefore, mental health should start with children. The multidisciplinary and multisector nature of child mental health will be further improved: medicine, economics, sociology, and other disciplines will pay close attention to child mental health. In particular, the only-child problem, the problems experienced by elderly parents in raising a second child, the problem of left-behind children, AIDS-infected children, Internet addiction problems, youth suicide, and crime prevention problems will become the focus of social attention. There will be new breakthroughs in early diagnosis and interventions for child mental health disorders: the ICD-11 (containing input from Chinese experts) will soon be released. Early warning indicators for child psychological problems and quantitative assessment techniques for child mental health care will be promoted from the national level to the whole country. Like child vaccination, assessments and interventions for child psychological conditions will benefit every child, which will set a global precedent. Treatment methods for child mental health disorders will be qualitatively improved. In addition to the further optimization of the structure and dosage of antipsychotics, research on functional food will make significant progress, and the use of alternative medicine and traditional Chinese medicine for child mental health disorders will be further clarified. In conclusion, the development of child psychiatry in China is still far behind developed countries, but a golden age of rapid development is approaching. Research on prevention and control of major chronic non-communicable diseases in the Ministry of Science and Technology (No: 2016YFC1306100) None.

This systematic review was conducted to determine the prevalence of mental disorders among children and adults in Uganda. A comprehensive systematic search for relevant studies reporting prevalence of mental disorders in children or adults in Uganda was conducted inPubMed, Embase, PsycINFO, Scopus, Web ofScience databases and grey literature sources. Study was eligible if, validated instrument based on the International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders criteria to assess a mental disorder was used. Eligible studies were critically appraised, prevalence data extracted and pooled using the random-effects model. Certainty in the pooled prevalence estimates was evaluated using the Grading of Recommendation, Assessment, Development and Evaluation approach. A total of 632 records were obtained, of which 26 articles from 24 studies conducted in Uganda were included in the review. Overall and with moderate level of certainty, the prevalence of any mental disorder in Uganda was 22.9% (95% C.I 11.0%-34.9%) in children and 24.2% (95% C.I 19.8%-28.6%) in adults. Prevalence of anxiety disorders was 14.4% (95% C.I 4.9%-24.0%) in children and 20.2% (95% C.I 14.5%-25.9%) in adults. The prevalence of current depressive disorders was 22.2% (95% C.I 9.2%-35.2%) in children and 21.2% (95% C.I 16.8%-25.6%) in adults. Eating disorder and psychotic syndrome disorder were also reported. Our findings suggest that depression and anxiety disorders are common mental disorders in Uganda, affecting approximately one in four persons. The findings provide essential insights for health service planning, clinical practice, and future epidemiological research in Uganda.

Review question/objective The objective of the systematic review is to identify and synthesize the best available evidence on how parents experience living with a child with attention deficit hyperactivity disorder (ADHD) including their experiences of ADHD health care services. The review questions are: How does living with a child with ADHD affect family life?What are the parental challenges of having a child with ADHD?How do parents experience collaboration with health care settings and professionals? Background Attention deficit hyperactivity disorder is the most prevalent mental disorder among children and adolescents worldwide, and the incidence of ADHD has increased in recent years.1 Attention deficit hyperactivity disorder in children is characterized by inattention, hyperactivity and impulsivity, and these characteristics are often present before the age of seven. The prevalence estimates for ADHD vary considerably worldwide due to demographic, cultural and socioeconomic characteristics of the population as well as the various criteria used for diagnosis. However, it is estimated that the prevalence in school children aged between five and 12 is 4-7%.2,3 Attention deficit hyperactivity disorder occurs in all socioeconomic groups, although it is more frequent in lower socioeconomic groups in society.2-4 Children with ADHD have care needs that reinforce a multimodal approach. They are often treated with medication which is supplemented with a variety of psychosocial and psycho educational interventions to improve their functioning.5 Furthermore, ADHD can be complicated by co-morbid conditions such as depression, anxiety and conduct disorders. Compared with the general population, ADHD is also associated with an increased prevalence of physical conditions including asthma, food allergy, epilepsy and severe headaches.2,8 Attention deficit hyperactive disorder often presents with challenging behavior and is associated with impairment in social, familial, emotional, academic and behavioral functioning.6,7 Attention deficit hyperactivity disorder may impact the lives of children and their families, for example, it affects practical and psychological aspects of daily life, school life and social life.6,7 The lives of families with children with ADHD can be influenced by many factors.9 Studies on parenting experiences show that parents find it challenging to raise and support the child.1,6 Findings indicate that the parents are struggling to maintain a bearable family life and to learn how to successfully handle their child.1,6 In addition, parents raising children with ADHD experience more emotional distress, stress and exhaustion than parents raising children without ADHD.1 Raising a child with ADHD also affects the families' social life as parents are worried how the child with ADHD will behave if they go on visits, holidays etc.9 Mental illness is associated with stigma, and living with a child with ADHD seems to have a significant impact on the families' experiences of stigma.10 Parenting a child with ADHD may cause experiences of social isolation, negative public views and sometimes the characteristics of the child with ADHD provoke negative reactions and intolerance from other parents or family members.9,10 Thus, the parents are concerned how society will judge a child diagnosed with ADHD, and they fear that the diagnosis may have a negative impact on their child's future opportunities.10 Although the majority of studies imply that raising a child with ADHD affects family lives negatively, studies report that the parents benefit from early identification and help and support from professionals.11 Some families develop strategies to cope with the problems related to their child's disorder.6,12 Parenting experiences of living with a child with ADHD include experiences of ADHD care and treatment.20 Children with ADHD are cared for and treated in various settings both in and outside of medical settings. Parents may be challenged by coordinating care and treatment as the diverse settings and professionals do not always tend to collaborate.14,15,20 A study estimates that as the rate of mental illness in the child population continues to increase, an extended use of collaboration with health professionals such as school psychology services, public health nursing, hospital psychiatry etc. is an important factor in providing high quality services.13 Treatment and care for children with mental health problems can involve between six to ten professionals across sectors.13 Studies reveal different perceptions regarding parents' collaboration with professionals. On one hand, parents of children with ADHD are grateful for the help and support from professionals to provide the best possible care for their children.1,4 On the other hand, parents experience barriers to treatment and care, as it is provided in diverse settings with numerous professionals involved.14,15 In addition, professionals and parents may conceptualize ADHD differently and have different perceptions of what collaboration entails.11 Studies show that parents lack directions and help from professionals to make decisions concerning medication.16-18 ADHD treatment and care may also be compromised by lack of continuity of care and if health professionals do not meet the families' individual emotional and educational needs.4,20 Family factors such as conflicts within the family and the psychopathology of the parents may also contribute to barriers in treatment and care.4,19 The literature indicates that parenting children with ADHD is influenced and challenged in different ways.1,20 However, diverse perspectives exist as how parenting a child with ADHD influences the families' daily life, how the parents manage raising the child, which factors parents find important and helpful factors and how parents experience ADHD care in diverse settings and the involvement with professionals across sectors. Studies find that the parents need more intensive support to help their child in the best possible way, and it is also recommended that professionals must be aware of the families' situations and their needs.1,11 An initial search in the databases of PubMed, CINAHL, JBIConnect+, Cochrane Library and PsycINFO showed that no systematic review on this topic exists or in progress currently. It is necessary to aggregate knowledge to further understand parenting experiences of living with a child with ADHD including their experiences of ADHD health care services to identify important and helpful factors in care and treatment. This may contribute to knowledge on how professionals can support the families in managing their situations. It may also contribute to the pertinent discussion on continuity of patient care and on how health care services ought to be organized to ensure the best possible care and treatment for children with ADHD and their parents.

It remains unclear whether children and adolescents in the child welfare system (CWS) exhibit a higher prevalence of mental disorders compared with the general population. The objective of this study was to perform a systematic review and meta-analysis to assess the prevalence of mental disorders in the CWS.A ll of the epidemiological surveys assessing the prevalence of mental disorders in children and adolescents in the CWS were included. The pooled prevalence was estimated with random effect models. Potential sources of heterogeneity were explored using meta-regression analyses.E ight studies provided prevalence estimates that were obtained from 3104 children and adolescents. Nearly 1 child or adolescent of every 2 (49%; 95% confidence interval (CI) 43-54) was identified as meeting criteria for a current mental disorder. The most common mental disorder was disruptive disorder (27%; 95% CI 20-34), including conduct disorder (20%; 95% CI 13-27) and oppositional defiant disorder (12%; 95% CI 10-14). The prevalence of attention-deficit/hyperactivity disorder was estimated to be 11% (95% CI 6-15). The prevalence estimates of anxiety and depressive disorders were 18% (95% CI 12-24) and 11% (95% CI 7-15). Posttraumatic stress disorder had the lowest prevalence (4%; 95% CI 2-6). High prevalences of mental disorders in the CWS were reported, which highlights the need for the provision of qualified service. The substantial heterogeneity of our findings is indicative of the need for accurate epidemiological data to effectively guide public policy.

Objective To study the prevalence and socio-demographic correlates of mental disorders in Beijing residents. Methods The multi-stage stratified cluster random sampling method was used,19 874 residents aged 18 or above who had lived for more than six months in Beijing were selected. Face-to-face assessment was conducted by trained investigators by using the Chinese version of the Structured Clinical Interview for DSM-Ⅳ Axis Ⅰ Disorders-Patient Edition (SCID-Ⅰ/P) to find any mental disorders, and the Mini-Mental State Examination (MMSE) to screen for dementia and mental retardation. Those who were positive on MMSE (MMSE ≤ 17 for those who completed elementary education or less, ≤23 for those who completed middle school or above) were further assessed to confirm dementia and mental retardation by using the SCID. Results 16 032 (80.7%) out of 19 874 eligible residents completed the face-to-face assessment. Adjusted by age and gender, the lifetime prevalence of all mental disorders was 120.8‰ (1 937/16 032, 115.8‰-125.9‰), and the top three most common ones were major depressive disorder (527, 32.9‰), alcohol dependence and abuse (311, 19.4‰), and anxiety disorder, NOS (270, 16.8‰). The point prevalence of all mental disorders was 75.3‰ (1 207/16 032, 71.2‰-79.4‰), the top three were specific phobias (187, 11.7‰), anxiety disorder, NOS (186, 11.6‰), and major depressive disorder (162, 10.1‰).The prevalence of mental disorders was significantly higher in the elderly (OR=1.014) , female (OR=1.428) , unemployed (OR=1.096) , people having poor rapports with family (OR=1.686) or others (OR=1.901) , smoking (OR=1.129) or drinking (OR=1.262) . The prevalence of mental disorders was significantly lower in the urban residents (OR=0.840) , people in a higher level of education (OR=0.813) , people who had got married/remarried or who had partner (OR=0.689) , people who had no family history of any mental disorders (OR=0.405) . Conclusions Approximately 12% of Beijing residents may meet at least one diagnosis of mental disorder in their lifetime; The prevalence of mental disorders is associated with older age, female gender, lower level of education, rural dwelling, positive family history of mental disorders, and poor social support system.

AimsTo report pooled prevalence of all mental disorders among the general prison population in the United Kingdom (UK). This includes individuals in Young Offender Institutions (YOI), youth custody and adult prisons across all categories. A secondary aim explores possible sources of heterogeneity by performing subgroup and meta-regression analysis across certain covariates (e.g. sex of prisoner). We hypothesise that contemporary estimates of mental disorders are higher than the general population.BackgroundPrevalence of mental health problems among prisoners are considerably higher than the general population; this poses an important public health concern. Individuals who require diversion to appropriate psychiatric services are becoming embroiled in the revolving door of the criminal justice system. However, there are no up-to-date reviews assessing prevalence of mental disorders across the general prison population in the UK. This study aims to address this gap.MethodWe conducted a systematic search of PsycINFO (1923 – October 2019), MEDLINE (1946 – October 2019), EMBASE (1947 – October 2019) and Web of Science (all years) of articles reporting prevalence of mental disorders in UK prison populations (PROSPERO registration number: CRD42019132685). The Joanna Briggs Institute (JBI) Appraisal Checklist for Studies Reporting Prevalence Data assessed study quality and bias. Pooled prevalence of each mental disorder was calculated using Stata statistical software 16.0 via the metaprop command. Forest plots present prevalence estimates with study weights and associated 95% confidence intervals (CI). Overall, 20 studies satisfied inclusion criteria, comprising of 12,335 prisoners across England, Wales and Scotland.ResultWe identified higher rates of neurotic disorders (28.9%, 95% CI 0.71–74.7%), personality disorders (23.5%, 95% CI 13.6–35.2%), alcohol (22.7%, 95% CI 12.2–35.1%) and drug dependence (26.7%, 95% CI 15.0–40.4%). The lowest prevalence rates included schizophrenia (2.42%, 95% CI 0.78–4.84%), panic disorders (3.88%, 95% CI 3.17% – 4.64%), adjustment disorders (3.83%, 95% CI 1.19–7.84%) and intellectual disability (2.90%, 95% CI 0.90–5.80%). Meta-regressions for psychotic disorder and personality disorder revealed no significant differences across study year, sample size and gender.ConclusionOur prevalence estimates of mental disorders in prisons are higher than the general English population. However, we should acknowledge the influence of considerable heterogeneity. These findings demonstrate the need to quantify current prevalence of mental disorders amongst prisoners in the UK. We recommend for the government to consider performing an up-to-date census of psychiatric morbidity to facilitate service provision.

Prevalence of adolescent mental disorders in Kenya, Indonesia, and Viet Nam measured by the National Adolescent Mental Health Surveys (NAMHS): a multi-national cross-sectional study

Objectives:To examine: 1) changes in the prevalence of mental disorders and perceived need for professional help among children (ages 4 to 11) and youth (ages 12 to 16) between 1983 and 2014 in Ontario and 2) whether these changes vary by age and sex, urban-rural residency, poverty, lone-parent status, and immigrant background.Methods:The 1983 (n = 2836) and 2014 (n = 5785) Ontario Child Health Studies are provincially representative cross-sectional surveys with identical self-report checklist measures of conduct disorder, hyperactivity, and emotional disorder, as well as perceived need for professional help, assessed by integrating parent and teacher responses (ages 4 to 11) and parent and youth responses (ages 12 to 16).Results:The overall prevalence of perceived need for professional help increased from 6.8% to 18.9% among 4- to 16-year-olds. An increase in any disorder among children (15.4% to 19.6%) was attributable to increases in hyperactivity among males (8.9% to 15.7%). Although the prevalence of any disorder did not change among youth, conduct disorder decreased (7.2% to 2.5%) while emotional disorder increased (9.2% to 13.2%). The prevalence of any disorder increased more in rural and small to medium urban areas versus large urban areas. The prevalence of any disorder decreased for children and youth in immigrant but not nonimmigrant families.Conclusions:Although there have been decreases in the prevalence of conduct disorder, increases in other mental disorders and perceived need for professional help underscore the continued need for effective prevention and intervention programs.

Attention deficit hyperactivity disorder is the most prevalent mental disorder among children and adolescents worldwide. Parenting a child with attention deficit hyperactivity disorder is challenging and parents find it difficult to raise the child and struggle to get professional support. Research has shown how living with a child with Attention Deficit Hyperactivity Disorder influences the families' daily life. This includes how the parents manage to maintain a bearable family life, supportive or not supportive factors as well as parents' experiences of collaboration with professionals in diverse settings. The objective of this systematic review was to identify and synthesize the best available evidence on parenting experiences of living with a child with attention deficit hyperactivity disorder, including their experiences of health care and other services. This review considered research articles with qualitative data examining the experiences of parents of children with attention deficit hyperactivity disorder. The phenomena of interest were parenting experiences of living with a child with attention deficit hyperactivity disorder, including their experiences of health care and other services, and collaboration with professionals. Retrospective and prospective searches were conducted in MedNar, ProQuest Dissertations and Theses, PubMed, Embase, PsycINFO and CINAHL. The reference lists of the included research articles were searched for additional studies, and a search for cited citations in Web of Science was conducted. Two independent reviewers assessed articles selected for retrieval for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from the Joanna Briggs Institute, the Qualitative Assessment and Review Instrument. Data were extracted from research articles included in the review using the standardized data extraction tool from the Qualitative Assessment and Review Instrument. Qualitative research findings were pooled using the Qualitative Assessment and Review Instrument. This involved aggregation and synthesis of findings. A total of 21 research articles were included in the review. The review process resulted in 129 study findings that were aggregated into 15 categories. The categories generated six synthesized findings: 1) An emotional roller coaster between hope and hopelessness, 2) Mothers as advocates in a battlefield within the system and family, 3) Parental experiences in a crossfire of blame, self-blame and stigmatization, 4) Shuttling between supportive and non-supportive services and professionals, 5) Routines, structures and strategies within everyday life, and 6) Despite multiple challenges, it is not all bad. The findings illustrate the complexity of parental experiences that are influenced by guilt, hope, blame, stigmatization, exhaustion, reconciliation and professional collaboration. The findings address the impact attention deficit hyperactivity disorder has on the everyday family, and how parents seem to adapt to their life situation in the process of accepting their child's disorder. Health care systems and other professionals need to provide support and understanding to families of children with ADHD. Further research is needed to examine how professionals in health care settings can address the individual needs of the families and how future interventions may support the families and improve competences of health professionals.

Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent mental disorders in childhood. Apart from its main symptoms, the disorder causes major difficulties in education, social performance, and interpersonal relationships. Because rehabilitation is important for these patients to combat these issues, the use of virtual reality (VR) technology is useful. This study aims to highlight the possibilities of virtual reality in rehabilitation of children with ADHD. The application of virtual reality technology in ADHD is retrieved in this paper through literature research. By reviewing relevant research at home and abroad, the research findings to date are summarized, and the potential and opportunities of virtual reality technology in ADHD are summarized.

The prevalence of mental disorders is often assessed using survey techniques. Although providing good estimates of prevalence, these techniques are time-consuming and expensive. To estimate the prevalence of mental disorders among children aged 0 to 17 years living in Alberta, Canada, using health care administrative data. This was a cross-sectional study. International Classification of Diseases, Ninth Revision, Clinical Modification chapter 5 diagnostic codes from physician billing data were used. Codes were grouped into 10 categories. Prevalence rates for each category were calculated, stratified by age, sex, and premium subsidy status (a proxy for socioeconomic status). The age pattern, times of greatest risk, and the effect of sex on type and prevalence of mental disorder were estimated. All fee-for-service health care venues in Alberta between April 1, 1995, and March 31, 1996, providing services to children registered with the Alberta Health Care Insurance Commission on March 31, 1996. Prevalence of mental disorders varied by disorder category, age, sex, and premium subsidy status. For boys, maximum prevalence of 9.5% occurred at age 10 years; for girls, maximum prevalence of 12.0% occurred at age 17 years. Mental disorders were most common in young boys and adolescent girls and among children receiving welfare. Distinct patterns of disorder were evident and comorbidity was common. Administrative data can be used to estimate the prevalence of mental disorders in a pediatric population. The estimates made are lower than those obtained by using surveys of similar populations, perhaps indicating the difference between treated and untreated prevalence. Strengths of this study are that the estimates reflect the entire population, are more easily and obtained at less cost, and are useful for the planning of mental health services.
