Corrigendum: Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder Among Adults and Children/Adolescents in Korea

ADHD and “eye problems”

Background: There are numerous reports regarding increasing childhood and adolescent mental health problems. The aim of this study was to determine the prevalence of psychiatric disorders in Hamadan Province, west of Iran from July 2016 to May 2017.Study design: A cross-sectional study.Methods: The sample included 1025 Hamadan residents selected using multistage cluster sampling. Psychiatric disorders were assessed by semi-structured psychiatric interview Kiddie-Sads-Present and Lifetime Version (K-SADS-PL). The data were analyzed using the SPSS software. We used the multivariable logistic regression to predict the Odds Ratios (ORs).Results: The prevalence of total psychiatric disorder was 8.6%. Psychiatric disorders in boys were higher than girls (12.6% and 4.9%, respectively). The psychiatric disorders were most prevalent in 6-9 yr old age group (11%). The prevalence of behavioral disorder was 3.8% with attention deficit hyperactivity disorder (ADHD) as the most prevalent case (2.0%). The prevalence of anxiety disorder was 2.8% in which the highest prevalence belonged to separation anxiety disorder (SAD) (1.1%). The prevalence of neurodevelopment disorder was 1.5% with the highest prevalence of 1% observed in epilepsy. The prevalence of mood disorder was 1.1% with the depressive disorder as the most prevalent one (1.0%). The prevalence of enuresis was 2.7%. The most common comorbidities were anxiety and mood disorders 5(50.0%).Conclusion: The prevalence of these disorders in Hamadan was less than the prevalence in other cities of Iran. These findings can be helpful for large-scale planning for children and adolescents.

There is a high prevalence of neuropsychiatric disorders in myotonic dystrophy types 1 and 2 (DM1 and DM2), including autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) in DM1, and depression and anxiety in both DMs. The aim of this systematic review and meta-analysis was to estimate the prevalence of ASD, ADHD, depression and anxiety in the population with DM, and their association with disease onset. A systematic search of Medline, Scopus, Web of Science, and the Cochrane Library was conducted from inception to November 2023. Observational studies estimating the prevalence of these disorders in DM1 or DM2 were included. A meta-analysis of the prevalence of these disorders and an association study with disease onset by prevalence ratio meta-analysis were performed. Thirty-eight studies were included. In DM1, the prevalence of ASD was 14%, with congenital onset being 79% more common than juvenile onset, while the prevalence of ADHD was 21%, with no difference between congenital and juvenile onset, and the prevalence of depression and anxiety were 14% and 16%. Depression was more common in the adult onset. Finally, the prevalence of depression in DM2 was 16%. A higher prevalence of neuropsychiatric disorders is observed in individuals with DM1 and DM2 than in the general population. Therefore, actively screening for congenital and juvenile neurodevelopmental disorders in DM1 and emotional disorders in DM1 and DM2 may improve the quality of life of those affected.

Background: Children and adolescents are the potential capitals of communities. Therefore, their physical, mental, social, and spiritual health is of great importance. Objectives: This study aimed to evaluate the prevalence of psychiatric disorders among children and adolescents in Southern Khorasan province, Iran. Methods: This cross-sectional descriptive-correlational study was conducted in 2017. Study population consisted of children and adolescents aged 6–18 who lived in Southern Khorasan province, Iran. A sample of 1029 children and adolescents was selected through multistage cluster sampling. Data were collected using the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL) and analyzed using the SPSS software (v. 19.0) and by conducting the Fisher’s exact test. Results: The overall prevalence of psychiatric disorders among children and adolescents in Southern Khorasan province, Iran, was 15.2%. The prevalence of these disorders among male and female participants was 15.5% and 14.8%, respectively. Moreover, the prevalence was 13.1% in the 6 - 9 age group, 15.5% in the 10 - 14 age group, and 17% in the 15 - 18 age group. In addition, the prevalence of psychiatric disorders among participants who lived in urban and rural areas was 18.9% and 6.3%, respectively. The most prevalent psychiatric disorders were respectively separation anxiety (5.2%), obsessive-compulsive disorder (3.5%), generalized anxiety disorder (3%), enuresis (2.9%), oppositional defiant disorder (2.4%), depression, special phobias, attention deficit-hyperactivity disorder (1.6%), agoraphobia (1%), and social phobia (0.8%). Conclusions: Need-based age-appropriate mental health services are needed to promote mental health among children and adolescents.

Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood-onset psychiatric disorders. Although the onset of ADHD is frequently prior to the age of seven years, there is a paucity of data on the prevalence of the disorder in preschool-age children. This study was performed to determine the prevalence rate of ADHD in preschool-age children in kindergartens of Mashhad, North-East of Iran. One thousand eighty-three (553 males and 530 females) children aged between five and six years, were selected at random from 155 kindergartens in ten districts of Mashhad. The ten-item Conner's Index questionnaire was completed for each child by teachers and parents. Parents of children whose scores were positive for ADHD (>15) were interviewed by a psychiatrist and the ADHD was diagnosed based on DSM-IV diagnostic criteria and the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime Version. One hundred thirty-three (12.3%; CI 95%: 10.3 -14.2%) children were diagnosed to have ADHD. The prevalence of ADHD in preschool-age children in North-East of Iran is consistent with previous studies in other countries. This study recommends the need for diagnosis and treatment of ADHD in preschool-age children.

Many disorders in childhood and adolescence were already present in the preschool years. However, there is little empirical research on the prevalence of psychiatric disorders in young children. A true community study using structured diagnostic tools has yet to be published. All children born in 2003 or 2004 in the city of Trondheim, Norway, who attended the regular community health check-up for 4-year-olds (97.2% of eligible children) whose parents consented to take part in the study (N = 2,475, 82.0%) were screened for behavioral and emotional problems with the Strengths and Difficulties Questionnaire (SDQ). A screen-stratified subsample of 1,250 children took part in a furthermore comprehensive study including a structured diagnostic interview (the Preschool Age Psychiatric Assessment, PAPA), which 995 parents (79.6%) completed. The estimated population rate for any psychiatric disorder (excluding encopresis - 6.4%) was 7.1%. The most common disorders were attention deficit hyperactivity disorder (1.9%), oppositional defiant disorder (1.8%), conduct disorder (0.7%), anxiety disorders (1.5%), and depressive disorders (2.0%). Comorbidity among disorders was common. More emotional and behavioral disorders were seen in children whose parents did not live together and in those of low socioeconomic status. Boys more often had attention-deficit/hyperactivity disorder (ADHD) and depressive disorders than girls. The prevalence of disorders among preschoolers was lower than in previous studies from the USA. Comorbidity was frequent and there was a male preponderance in ADHD and depression at this early age. These results underscore the fact that the most common disorders of childhood can already be diagnosed in preschoolers. However, rates of disorder in Norway may be lower than in the USA.

There are no studies that measure the prevalence and real comorbidities of neurodevelopmental disorders (NDDs) according to the DSM-5-TR in 6-year-old children in population and clinical samples or studies that measure them as a whole. The data on the prevalence of these disorders are usually disparate because of the estimation methods (direct/indirect), the type of sample (population/clinical/school), and the ages studied. The initial sample (289 subjects) was representative of 6-year-old children in the entire population of Menorca, obtained from pediatric primary care services (100% of the sample). The patients were divided into two groups based on the criterion of verification of clinical warning signs. One of the groups represented the clinical or experimental sample (EG) (81 subjects) at risk of NDDs; the other group was considered the control sample (CG) (210 subjects), and they were subjects without risk of suffering NDDs. A direct clinical assessment of the clinical sample was carried out, and they were administered the Wechsler Intelligence Scale for Children (WISC-V), the Clinical Evaluation of Language Fundamentals (CELF-5), the Battery for the evaluation of the processes of revised reading (Batería para la evaluación de los procesos de lectura revisada - PROLEC-R), the Test for the Diagnosis of Basic Mathematical Competences, (TEDI-MATH), and the Developmental Coordination Disorder Questionnaire (DCDQ). A total of 21.5% of the initial sample suffered from an NDD. A total of 2.4% presented autism spectrum disorder (ASD); 14% presented attention-deficit hyperactivity disorder (ADHD); 0.34% presented mild intellectual disability; 9.54% presented communication disorder (CD) (5.8% language disorder, 3.4% phonological disorder, and 0.34% stuttering); 10% presented learning disorder with reading difficulties; 5.8% presented learning disorder with difficulties in writing; 3.11% presented learning disorder with difficulties in mathematics; 1% presented transitory tic disorder; 0.34% presented chronic tic disorder; 1% presented Tourette syndrome; 2% presented motor coordination disorder (MCD); and 0.34% presented stereotypic movement disorders. Male children were more affected than female children in general, with male/female ORs of 0.14/0.92 for the presence of comorbidities, 0.11/0.88 for combined ADHD, 0.06/0.87 for language disorder, 1.02/1.27 for MCD, and 1.39/1.02 for inattentive ADHD. In disadvantaged contexts, there was a higher prevalence of NDDs and comorbidities, unless the disorder was extreme, in which case only the NDD manifestations were presented. A significant proportion of the sample had not been previously diagnosed (88.6%); therefore, early detection programs are recommended to identify warning signs and develop policies that help and support the most disadvantaged sectors of the population.

Objective To explore the prevalence of attention deficit hyperactivity disorder (ADHD) and its associated factors among college students in Changsha, so as to provide evidence of for effecive intervention of ADHD. Methods A total of 8 080 students from two universities in Changsha were investigated with self-designed general situation questionnaire, Chinese version of Wende Utah adult rating scale for ADHD, World Health Organization (WHO) Adult ADHD Scale (ASRS) and Chinese Internet Scale (CIAS-R). Results The self-report rate of ADHD was 7.2%. Single factor analysis showed that the incidence of ADHD in gender, physical and mental illness history, family history of mental illness, relationship with parents, smoking, drinking and Internet access were statistically significont ( χ 2 = 17.68, 22.25, 43.15, 20.73, 18.61, 43.05, 22.81, 53.55, 719.65, P <0.05). Multivariate Logistic analysis showed that the younger the age, mental illness, drinking, the higher the degree of Internet dependence were positively correlated with ADHD, while gender (female) and harmony with father were negatively correlated with ADHD. Conclusion ADHD in college students can’t be ignored. There are many influencing factors, suffering from mental illness, drinking and Internet addiction. 【摘要】 目的 了解长沙市大学生注意缺陷多动障碍 (attention deficit bperactivit), disorder, ADHD)的现况, 为有效干预 ADHD提供参考。 方法 采用整群抽样的方法, 对长沙市2所大学共8 080名学生采用自编一般情况问卷、中文版文德犹 他ADHD成人评定量表、世界卫生组织 (WHO)成人ADHD自评量表vl.l症状自评量表和中文网络成瘾量表 (CIAS-R)进 行问卷调查, 对筛查结果进行统计。 结果 大学生ADHD检出率为7.2%。单因素分析显示, ADHD的发生在性别、躯体以 及精神疾病史、精神疾病家族史、与母亲/父亲关系、吸烟、饮酒和网络成瘾等方面差异均有统计学意义 ( χ 2 值分别为17.68, 22.25,43.15,20.73, 18.61, 43.05,22.81, 53.55,719.65, P 值均<0.05)。 多因素 Logistic 回归分析显示, 年龄小、精神疾病史、 饮酒频繁、网络成瘾与ADHD发生均呈正相关, 而性别 (女性) 和与父亲相处和睦与大学生ADHD发生呈负相关 ( P 值均< 0.05)。 结论 大学生中ADHD不容忽视, 发生的影响因素较多, 与罹患过精神类疾病、饮酒和网络成瘾行为相关, 可采取 多种措施开展针对性的干预。

Prevalence of Psychiatric Disorders in Youths Across Five Sectors of Care

Prevalence of sleep disorders in patients with neurofibromatosis type 1

BackgroundLooked after children (LAC) that are placed in either a foster, kinship, residential care setting or transition to adoption continue to develop debilitating disorders that significantly impact their overall health and social well-being. The prevalence of these disorders is often depicted under broad categories such as mental, behavioural or neurodevelopmental disorders (NDDs). Limited in research is the prevalence of what specific disorders fall under these broad categories. NDDs such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) which fall under an umbrella group in the expert field of genetics and neuropsychiatry will be explored. Unsupported, these disorders can lead to suboptimal health and social outcomes for both the child and family. In the general population, the prevalence of these NDDs and impacts on health and social well-being are relatively well documented, but for minority groups such as LAC, research is extremely limited. This review aims to estimate the prevalence of NDDs among LAC and explore how they might impact the health and social well-being of these vulnerable children. If feasible, the review will compare the prevalence rates to those children who are not looked after, to illuminate any differences or similarities between populations.MethodsPubMed, ASSIA, IBSS, Web of Science, PsychINFO, Scopus, Psych articles, Social Care Online, secondary, grey literature and government publications will be searched to identify any eligible studies. No restrictions will be placed on country, design or year of publication. Studies must provide primary data on the prevalence or incidence of NDDs for individuals < 25 years of age, supported by either a diagnostic code, standardised diagnostic assessment tool or survey response. The Joanna Briggs Institute (JBI) critical appraisal tools will be utilised to assess the quality and bias and the random-effects model used to estimate a pooled prevalence of NDDs.DiscussionAttaining an estimated prevalence of these NDDs and identifying any impacts on health and social well-being might inform key stakeholders in health, educational and social sectors with important information that might aid in the early identification and intervention to safeguard and meet the unique needs of these children.Systematic review registrationPROSPERO CRD4201913103.

Currently, there is a paucity of studies on the prevalence of Elimination Disorders among Iranian children and adolescents. Due to the ongoing need to monitor the health status of these children and adolescents, the present study aims to investigate the prevalence of Elimination Disorders and comorbid disorders in Iranian children and adolescents. In this cross-sectional study, 29,781 children and adolescents age 6 to 18 years old were selected and studied from all the provinces in Iran. The sampling was carried out by employing a multistage cluster sampling method, and several clinical psychologists using semi-structured interviews collected the data. Furthermore, clinical psychologists collected demographic information (including information about gender, age, place of residence, education level, and parental education level). The collected data were analyzed using SPSS version 20. Generally, the prevalence of Elimination Disorders was found to be 5.4% covering both enuresis (p= 5.4, 95% CI = 5.1-5.7) and encopresis (p= 0.13, 95% CI = 0.09-0.2). The total prevalence of comorbid disorders was 38%, and among the comorbid disorders, Attention Deficit Hyperactivity Disorder (ADHD) (p= 11, 95% CI = 9.5-12.7) and Separation Anxiety (p= 10.6, 95% CI = 9.1-12.2) were the most prevalent. The prevalence of Elimination Disorders in Iranian children and adolescents is moderate compared to similar studies elsewhere. As for comorbid disorders, ADHD and Separation Anxiety were found to be the most prevalent disorders. Since Elimination Disorders coexist with psychiatric disorders in children, further studies of these comorbidities may give better insight into the treatment and prognosis of Elimination Disorders.
