Long-term liver deportalisation in stable and time prolonged prehepatic portal hypertension model affects expression of hypoxia, angiogenesis, apoptosis, and autophagy markers in the young rats’ liver

prehepatic portal hypertension in children cause severe and life-threatening complications, that highlights the need in in-depth investigations of pathogenetic mechanisms, which contribute to prehepatic portal hypertension-associated liver pathology. In developed stable experimental prehepatic portal hypertension model in adolescent rat males we aimed to assess the expression levels of the key molecular markers of hypoxia, angiogenesis, autophagy, and apoptosis in the liver tissue after 6-month deportalization. Partial portal vein ligation was performed in 4-week old male rats. After 6-months tissue samples from PHP-model, sham operated and control animals were studied by western blot to identify protein levels of markers related to prehepatic portal hypertension -induced liver injury. Partial portal vein occlusion upregulated hypoxia inducible factor -1α (by 4.67 folds vs. control, p<0.001) and vascular endothelial growth factor protein expression levels (by 2.33 folds vs. control, p<0.001) suggesting chronic hypoxia development. Abnormally high levels of angiostatin isoforms were found (by 9.88 folds vs. control, p<0.001) to signify angiogenesis dysregulation. Significant caspase-3 (23.4-fold increase vs. control, p<0.001) overexpression is executive phase of apoptotic cell death evidence. Dramatic LC3 level expression indicates existence of crosstalk between autophagy and apoptosis that contribute to fibrotic changes. Hypoxia-induced events, impaired angiogenesis regulation, enhanced autophagy and apoptosis are contributing factors of prehepatic portal hypertension -induced liver injury. A better understanding of subtle molecular mechanisms of this pathology may pave the way for innovative treatment options.

Sleepless in the Pursuit of perfection: A longitudinal investigation of bidirectional relationships between insomnia and perfectionism in Adolescent males and females

Study objectivesPerfectionism is a possible risk factor for insomnia, yet longitudinal evidence of this relationship in adolescence is lacking. Cross-sectional evidence suggests the nature of the relationship may differ based on biological sex, and the form of perfectionism, since socially prescribed and self-oriented critical perfectionism are conceptualised as maladaptive for wellbeing, while self-oriented striving may be adaptive or neutral. This study aimed to investigate longitudinal bidirectional relationships between total perfectionism, and sub-forms of perfectionism (i.e., socially prescribed, self-oriented critical, self-oriented striving perfectionism), and symptoms of insomnia, over the course of mid-adolescence. Longitudinal models were examined for males and females separately. Methods434 adolescents (Mage = 14.25, SD = 0.56, range = 13–16, 52 % male) completed questionnaire measures of perfectionism (Child-Adolescent Perfectionism Scale) and insomnia (Insomnia Severity Index) on three annual occasions (at approximately 14, 15 & 16 years of age). Data were from the larger Risks to Adolescent Wellbeing (RAW) Project. ResultsBiological sex did not moderate the association between insomnia symptoms and any form of perfectionism. Cross-lagged panel models showed no longitudinal relationship between self-oriented striving, nor self-oriented critical perfectionism and insomnia symptoms for males or females. Higher total perfectionism predicted moderate increases in insomnia symptoms for males and females, but insomnia symptoms did not predict changes in total perfectionism. Socially prescribed perfectionism and insomnia symptoms predicted large and moderate increases in one another over time, respectively, forming a perpetuating cycle. ConclusionsResults suggest that perfectionism may be an important risk factor for insomnia symptoms in adolescents.

Exploring the efficacy of memory specificity training on depression among Iranian adolescents: a comparative analysis of online vs. in-person delivery

Depression in adolescence is common worldwide, with the burden being highest in low- and middle-income countries. This study assessed the efficacy of in-person Memory Specificity Training (MeST) and computerized MeST (c-MeST) as cognitive training programs aimed at addressing depression among Iranian adolescents. A secondary aim was to evaluate the efficacy of MeST and c-MeST on autobiographical memory specificity, emotion regulation and cognitive control. Ninety Iranian male adolescents (aged 13–18 years) with depression were randomly assigned to three groups; MeST group (n = 30), c-MeST group (n = 30) and the non-active control group (n = 30). Participants completed the Beck Depression Inventory-II, Autobiographical Memory Test, Cognitive Emotion Regulation Questionnaire, Wisconsin Card Sorting Test and Stroop Color and Word Test. The groups underwent either MeST and c-MeST. All the assessments were re-conducted after the intervention (post-intervention) and at 1-month post-intervention (follow-up). The in-person MeST group exhibited significantly higher autobiographical memory specificity at post-intervention and follow-up compared to the c-MeST group. Both groups demonstrated significantly lower levels of depression at post-intervention and follow-up. Both groups showed improvements in emotion regulation and cognitive control, which were found to mediate improvements in depression symptomatology. c-MeST and MeST appear promising brief interventions for the treatment of depression among adolescents in Iran.

Alcohol Abuse and Physical Violence towards a Partner: How Can We Attenuate the Relationship? A Study on Emotional Dysregulation in Adolescents.

The previous literature has revealed the relationship between alcohol abuse and violent behaviours; however, the results are not always conclusive, highlighting the need to explore other variables that allow us to establish risk profiles. The goal is to examine whether the relation between alcohol abuse and physical violence towards a partner can be influenced (moderate) by difficulties in emotional regulation. A public high school in Manabí (Ecuador). A total of 1519 high school students with ages between 14 and 18 years (mean = 15.77, SD = 1.22), with 54% (n = 820) being male. The measures we observed were alcohol abuse (i.e., frequency of alcohol abuse in the past 30 days), physical violence exercised towards a partner (Violence Received, Exercised and Perceived in Dating Relationships of Young People and Adolescents) and emotional dysregulation (Difficulties in Emotional Regulation Scale; DERS). It is observed that there exists significantly higher alcohol abuse in males, regardless of their age, as well as more physical violence by adolescent males towards their partners. Direct effects of alcohol abuse on physical intimate partner violence are observed in males from the age of 16 and in females from the age of 14. Moreover, the direct effects of different emotional dysregulation strategies on physical violence depend on gender. The moderating effects of emotional dysregulation strategies between alcohol abuse and physical intimate partner violence are observed only in the case of adolescent females (16-17 years). In particular, emotional dysregulation variables such as non-awareness, impulse, nonacceptance, or lack of strategies interfere as moderators in the relationship between excessive alcohol abuse and physical violence towards a partner. In the case of non-awareness, contrary to the other three, when scores are low or moderate, a statistically significant relationship between alcohol abuse and violence is observed.

Some correlates of body dissatisfaction in urban school students

Background. Body dissatisfaction is widely spread among the population. It negatively affects human health, contributing to the development of eating disorders, anxiety and depressive disorders, and the formation of unhealthy eating patterns and lifestyle. Determining the factors associated with body dissatisfaction in adolescents may be important for the prevention of the above mentioned disorders.The aim of the work. To describe the prevalence, characteristics and factors associated with body dissatisfaction among urban school students.Materials and methods. Tenth-grade school students (n = 440) underwent anthropometry and also filled out questionnaires including socio-demographic factors and lifestyle factors. Collins scales were used to assess body dissatisfaction, and the Russian version of the Paediatric Quality of Life Inventory (PedsQL 4.0; Lyon, France) was used to assess health-related quality of life.Results. 60.2 % of school students reported a desire to have body figures different from the actual one. 42.7 % of adolescents experienced mild body dissatisfaction, 17.5 % experienced moderate and severe body dissatisfaction. The frequency of body dissatisfaction was comparable among both male and female adolescents, but it was more pronounced among girls compared to boys (Z = 2.2; p = 0.029). Boys were significantly more likely than girls to strive for larger body figures than what they felt they had (38.8 % vs. 8.1 %). In contrast, girls were significantly more likely than boys to want to lose weight (55.4 % vs. 12.3 %). Statistically significant associations with moderate/severe body dissatisfaction are shown for overweight/ obesity and for the time spent by schoolchildren watching TV, on social networks, and in the Internet. Sports activities demonstrated a protective role in relation to body dissatisfaction. The presence of body dissatisfaction significantly reduced all aspects of adolescents’ quality of life.Conclusions. The results of the study justify the approach to body dissatisfaction as an independent problem that requires active diagnostics and targeted exporure, and determine possible directions for preventive measures among adolescents.

Association between endogenous sex hormones and adiposity in youth across a weight status spectrum.

While endogenous sex hormones (e.g., testosterone, estradiol) are important factors regulating adipose tissue distribution, studies evaluating such relationships in youth across a wide weight status spectrum are limited. We performed a cross-sectional analysis of 8-21-year-old youth. Multiple linear regression models were used to evaluate associations between sex hormones and adiposity measures (android/gynoid ratio (A/G), total fat mass (FM), visceral adipose tissue (VAT), waist circumference (WC)) and total lean mass (LM), adjusting for pubertal stage and race/ethnicity, and stratified by sex and weight status. Among 342 youth, the mean age was 13.0 ± 2.8 years old (52.6% female; 38.9% normal weight [NW]; 27.8% overweight/obesity [OW/OB]; 33.3% severe obesity [SO]). Testosterone was positively associated with LM among males with NW (1462 g, 95% CI: 255-2668 g) and OW/OB (3792 g, 95% CI: 1244-6340 g), with A/G and WC among males with NW (0.01, 95% CI: 0-0.2 and 10 mm, 95% CI: 4-16 mm, respectively), and negatively associated with WC among males with SO (-43 mm, -81 to -5 mm). Estradiol was positively associated with A/G, FM, and WC among males with SO, and VAT in females with NW. Our findings showed that sex hormones were associated with adipose tissue deposition in youth across the weight spectrum. Sex hormones (e.g., testosterone, estradiol) are associated with various adiposity measures among male and female children and adolescents across a weight status spectrum. We evaluated associations between sex hormones and various adiposity measures among 8-21-year-olds across a weight status spectrum (normal weight, overweight/class 1 obesity, class 2-3 obesity). We found that estradiol was positively associated with total fat mass, android/gynoid ratio, and waist circumference in males with class 2-3 obesity, and testosterone was positively associated with lean mass in males with normal weight and overweight/class 1 obesity. Sex hormones may influence, or may be influenced by, adiposity in youth.

Eating disorders and health literacy in Germany: results from two representative samples of adolescents and adults.

Eating disorders are associated with substantial burden for the affected individuals including negative health outcomes and increased mortality. So far, prevention programs for eating disorders have yielded mixed results concerning their efficacy. Therefore, more targeted prevention programs need to be developed. Health literacy has been identified as a potential influencing factor of eating disorders. This study aimed at exploring the relationship between likely cases of eating disorders and health literacy, alongside additional sociodemographic factors. Two large samples of adults (N = 3,011) and adolescents (N = 1,021) representative of the German-speaking population in Germany were recruited. Likely cases of eating disorders were identified using the SCOFF questionnaire. Health literacy was assessed with the HLS-EU-Q16 questionnaire. Sociodemographic information, including age, gender, social status and level of education, and subjective body image were obtained. χ2-tests of independence were calculated to determine the association between the investigated constructs. Suspected eating disorders were more likely in female than male adolescents but were not related to gender in adults. Rates of suspected eating disorders increased with increasing age in adolescents and decreased with increasing age in adults. While levels of education were unrelated to suspected eating disorders, low social status was associated with higher rates of suspected eating disorders in adults but not adolescents. Inadequate or problematic health literacy and negative body image were associated with higher rates of suspected eating disorders compared to adequate health literacy and more positive body image. Likely cases of eating disorders are related to health literacy and body image as well as sociodemographic factors. These constructs should therefore be addressed in future research to improve prevention programs.

Smile stimuli induce better performance in tests performed by children and adolescents practicing jiu-jitsu

Aims: This study compared the performance of children and adolescents practicing jiu-jitsu when stimulated or not stimulated to smile before specific and non-specific physical tests. Methods: 268 children and adolescents (male=168) were measured in 5 tests (30” by 3’ interval) of which 3 were specific (4-Leg Exercise, Gyaku-tsuki test and O-soto-otoshi nage-komi test) and 2 non-specific (Side jumps and Burpees). These tests were carried out under two conditions: a) without prior stimuli; b) after joy stimuli. Results: There was an isolated effect of the pre-test intervention for non-specific tests, with better performance after joy stimuli (Side jumps: 35.8±13.3 vs. 30.1±11.1; Burpees: 16.1±5 .3 vs. 13.8±4.8 repetitions; p≤0.001 for both comparisons). There were also isolated effects of the pre-test intervention for the specific O-soto-otoshi nage-komi test and 4-Leg Exercise, where happiness stimuli resulted in better performance (O-soto-otoshi nage-komi test: 15.2±3.5 vs. 12.5 ± 3.7 repetitions; 4-Leg Exercise: 3.5±1.2 vs. 2.8±1.2 repetitions p≤0.001 for both comparisons). For the Gyaku-tsuki test, there was an interaction effect between intervention and age (p=0.02), where older children performed better. Conclusion: Stimulating emotions of happiness brings better performance in children and adolescents practicing jiu-jitsu regardless of gender and age, except for the Gyaku-tsuki test where older people tend to perform better. Keywords: martial arts, emotion, children, adolescent, performance.

Do Attitudes towards Gender Equality Influence the Internalization of Ambivalent Sexism in Adolescence?

Sexism during adolescence may hinder the attainment of gender equality and the eradication of violence against women. The aim of this research was to analyze the relationship between an individual's view on gender equality and the internalization of ambivalent sexism, as well as to study the impact of different types of egalitarian attitudes (sociocultural, relational, and personal) on the levels of hostile and benevolent sexism among the adolescent population. A quantitative approach with a cross-sectional design was employed in this research. The sample group consisted of 1840 students (50.1% female and 49.9% male) in Compulsory Secondary Education in Castilla-La Mancha, Spain. The results show that adolescents who endorse pro-gender-inequality attitudes exhibit greater levels of hostile and benevolent sexism than their counterparts. Conversely, adolescents adopting pro-equality attitudes leads to lower levels of ambivalent sexism. In both male and female adolescents, egalitarian attitudes at the sociocultural, relational, and individual levels have a negative impact on the internalization of sexism. It is therefore crucial for both schools and families to prioritize the instruction of egalitarian values from early childhood, as this will aid in advancing a fairer and more equal society whilst eradicating sexist biases and violence against women.

Impact of Locus of Control on Psychological Well-Being Among Male and Female Adolescents in Anambra State

This study focused on investigating how locus of control influences the mental well-being of male and female adolescents from Anambra State, Nigeria. The type of research study was correlational and the respondents were senior Secondary School students of which 396 were males and 367 females. The sampling methods used were multistage and stratified sampling. In data collection the Locus of Control of Behaviour Scale (LCBS) and the Psychological Well-Being Scale (PWS) were used; both instruments yielded high reliability as assessed by Cronbach’s alpha coefficients of 0. 72 and 0. 86, respectively. Specifically, in the regression equations it was discovered that locus of control has a positive correlation with psychological well-being and explained 21% of the variability. It accounts for 8% of the variability in all adolescent youth, 18. 1% among males and 24% among females. The findings underscored the significance of building an internal sense of control to improve adolescents’ psychological adjustment. The study revealed the need to apply such methods to enhance the students’ perceived control in educational programs and calls for future studies to discover other factors that have an impact on psychological well-being across various cultures.

Examining Factors in the Decision to Sperm Bank by Adolescent and Young Adult Males Diagnosed With Cancer: A Review of the Literature.

Background: Despite American Society of Clinical Oncology and Children's Oncology Group recommendations, the rate of sperm-banking for newly diagnosed adolescent and young adult males with cancer remains between 18% and 35%. The purpose of this study was to examine recent literature regarding decision-making and fertility preservation prior to the initiation of therapy for adolescents and young adults diagnosed with cancer. Method: A search of multiple online databases was undertaken for peer-reviewed studies between the years of 2010 and 2022. The databases CINAHL, PubMed, PsycInfo, Scopus, Google Scholar, and forward citation search was employed using the same Boolean search phrases in each database. Some 402 articles were then screened for relevance by title, abstract, and full review based on inclusion/exclusion criteria for synthesis. Results: Ten articles met criteria to be included in this review. Three themes were identified as impacting the decision to cryopreserve sperm prior to the initiation of therapy. Provider recommendation, parent recommendation, and referral for fertility specialist consult emerged as statistically significant factors in the decision to attempt sperm banking. Discussion: While the most significant factor impacting the decision to preserve fertility, parents reported they were more likely to recommend this to their child if they received clear recommendations from the medical team. Pediatric oncology physicians and nurses are in a unique position to positively impact quality of life and psychosocial outcomes in survivors of pediatric cancer by providing up-to-date evidence-based information, risk assessment, recommendations, and/or referral to fertility preservation specialists to families and patients.

The burden of acute eye conditions on different healthcare providers in Wales: a retrospective population-based study

Objective & ApproachDemand for urgent eyecare exponentially outstrips public healthcare capacity in the United Kingdom. Such eye conditions, and related vision impairment, affect the lives of people everywhere. We aimed to quantify the burden of urgent eyecare on primary- and community-care providers in a national population using data produced by General Practitioner, Accident and Emergency, pharmacy and optometry services. A secondary aim was to characterise some drivers of this burden. We analysed data from the Secure Anonymised Information Linkage Databank (linked), Eye Health Examination Wales Service (unlinked) and Common Ailments Scheme (unlinked) during 2017-2018 to quantify burden. We applied generalised linear modelling and logistic regression to understand drivers. ResultsOf 365,044 episodes of care during the study, GPs and A&E managed 46.2% (168,877) and 1.4% (5,122) respectively while optometrists and pharmacists managed 51.8% (116,868) and 0.6% (2,635). Older females and infants of both sexes were more likely to use GP prescribing services, while adolescent and middle-aged males were more likely to visit A&E. GP prescribing burden was driven partially by economic deprivation, access to local services, and overall community health. Season, day of the week, and time of day were predictors of burden for GP and A&E services. Conclusion & ImplicationsAcute eyecare continues to place considerable burden on primary care services in Wales, particularly in urban areas with greater deprivation. This is likely to increase with an ageing population. With ongoing pathway development to better utilise community care, there may be scope to change this trajectory.

Effect of Age and Gender on Nasalance Across the Lifespan: A Systematic Review.

The Nasometer® is a widely used clinical and research tool with diagnosis and outcome measurement utility. The objective of this study was to systematically examine the effect of age and gender on nasalance across the lifespan. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews (PRISMA 2020). University. Children, adolescents, adults, and older adults. Covidence Better Systematic Review Management; Scottish Intercollegiate Guidelines Network Methodology (SIGN) Checklist 3 for risk of bias; Levels of evidence, Oxford Centre for Evidence-Based Medicine Levels of Evidence hierarchy; and effect size calculations using G*Power 3. Nasalance (%) from the Nasometer™. 50 studies (from N = 1884) were included in the review. All were Level 3 (non-randomized controlled cohort) observational-analytic type studies. Only 10 (20%) of studies met a High Quality (low risk of bias) rating. Effect sizes were moderate for adults versus children ( d = 0.717) and adults versus adolescents ( d = 0.521) for oral text/passage. Gender differences were clinically significant for adolescent males and females with a moderate effect size ( d = 0.545) for oronasal text/passage. The systematic review provides objective and defined evidence as to the effects of age and gender on nasalance. Separate normative databases are implicated for specific age subgroups across the lifespan and for gender, particularly in adolescence. Review findings are applicable to other clinical groups where acquisition and/or progression occurs in adulthood/older adulthood.

Effects of Heat Stress-Induced Sex Hormone Dysregulation on Reproduction and Growth in Male Adolescents and Beneficial Foods.

Heat stress due to climate warming can significantly affect the synthesis of sex hormones in male adolescents, which can impair the ability of the hypothalamus to secrete gonadotropin-releasing hormone on the hypothalamic-pituitary-gonadal axis, which leads to a decrease in luteinizing hormone and follicle-stimulating hormone, which ultimately negatively affects spermatogenesis and testosterone synthesis. For optimal spermatogenesis, the testicular temperature should be 2-6 °C lower than body temperature. Heat stress directly affects the testes, damaging them and reducing testosterone synthesis. Additionally, chronic heat stress abnormally increases the level of aromatase in Leydig cells, which increases estradiol synthesis while decreasing testosterone, leading to an imbalance of sex hormones and spermatogenesis failure. Low levels of testosterone in male adolescents lead to delayed puberty and incomplete sexual maturation, negatively affect height growth and bone mineral density, and can lead to a decrease in lean body mass and an increase in fat mass. In order for male adolescents to acquire healthy reproductive capacity, it is recommended to provide sufficient nutrition and energy, avoid exposure to heat stress, and provide foods and supplements to prevent or repair testosterone reduction, germ cell damage, and sperm count reduction caused by heat stress so that they can enter a healthy adulthood.

Cardiac manifestations and outcomes of COVID-19 vaccine-associated myocarditis in the young in the USA: longitudinal results from the Myocarditis After COVID Vaccination (MACiV) multicenter study

We aimed to study the clinical characteristics, myocardial injury, and longitudinal outcomes of COVID-19 vaccine-associated myocarditis (C-VAM). In this longitudinal retrospective observational cohort multicenter study across 38 hospitals in the United States, 333 patients with C-VAM were compared with 100 patients with multisystem inflammatory syndrome inchildren (MIS-C). We included patients ≤30 years of age with a clinical diagnosis of acute myocarditis after COVID-19 vaccination based on clinical presentation, abnormal biomarkers and/or cardiovascular imaging findings. Demographics, past medical history, hospital course, biochemistry results, cardiovascular imaging, and follow-up information from April 2021 to November 2022 were collected. The primary outcome was presence of myocardial injury as evidenced by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging. Patients with C-VAM were predominantly white (67%) adolescent males (91%, 15.7±2.8 years). Their initial clinical course was more likely to be mild (80% vs. 23%, p<0.001) and cardiac dysfunction was less common (17% vs. 68%, p<0.0001), compared to MIS-C. In contrast, LGE on CMR was more prevalent in C-VAM (82% vs. 16%, p<0.001). The probability of LGE was higher in males (OR 3.28 [95% CI: 0.99, 10.6, p=0.052]), in older patients (>15 years, OR 2.74 [95% CI: 1.28, 5.83, p=0.009]) and when C-VAM occurred after the first or second dose as compared to the third dose of mRNA vaccine. Mid-term clinical outcomes of C-VAM at a median follow-up of 178days (IQR 114-285 days) were reassuring. No cardiac deaths or heart transplantations were reported until the time of submission of this report. LGE persisted in 60% of the patients at follow up. Myocardial injury at initial presentation and its persistence at follow up, despite a mild initial course and favorable mid-term clinical outcome, warrants continued clinical surveillance and long-term studies in affected patients with C-VAM.

Sex-related inequalities in current cigarette smoking among adolescents in Africa

IntroductionRisky behaviours, including tobacco use, are highly prevalent among adolescents worldwide. Although these behaviours are largely influenced by various sociodemographic factors, including sex, there is a paucity of regionally representative literature on the sex-related inequalities in cigarette smoking among adolescents in Africa. This study examined the sex-based disparities in current cigarette smoking among adolescents aged 13–15 years in Africa.MethodsThe present study employed a secondary analysis of nationally representative data on 45 African countries obtained from the Global Youth Tobacco Survey, accessible through the World Health Organization (WHO) Global Health Observatory. We used the online version of the WHO Health Equity Assessment Toolkit (HEAT) to generate the results.ResultsThe prevalence of current cigarette smoking among the adolescents surveyed ranged from 1.6% in Eritrea to 10.4% in Mali among the low-income countries, from 1.3% in Tanzania to 13.1% in Mauritania among the lower-middle-income countries, from 5.2% in Gabon to 15.3% in Mauritius among the upper-middle-income countries, and 14.7% in Seychelles, the only high-income country in the study. The absolute summary measure (D) showed diverse sex-related disparities in the burden of current cigarette smoking among adolescents across the sub-regions. In all countries surveyed, the prevalence of cigarette smoking was higher among male adolescents compared to females, except in Liberia and Mozambique, where female adolescents bore a more significant burden than their male counterparts. Furthermore, male adolescents were more burdened with high cigarette smoking prevalence than females in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia, where such disparities were most pronounced. Meanwhile, we found less disparity in the burden of cigarette smoking between male and female adolescents in most of the lower and upper-middle-income countries surveyed.ConclusionThis study sheds light on the sex-based inequalities in the prevalence of current cigarette smoking among adolescents in Africa. In contrast to female adolescents, male adolescents bear a greater burden of current cigarette smoking. The burden of cigarette smoking is most pronounced in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia. Conversely, in most of the lower and upper-middle-income countries surveyed, the burdens of current cigarette smoking among male and female adolescents were found to be less disparate. Consequently, cigarette smoking prevention programmes and strategies must be implemented in all African nations. There is also the need to intensify interventions aimed at altering the smoking behaviour of male adolescents. Policymakers can develop and implement evidence-based interventions to address the burden of cigarette smoking among the adolescents. Finally, existing policies and programmes addressing adolescents' cigarette smoking should be re-assessed and strengthened to achieve their objectives.

Prospective associations between an empirically derived dietary pattern and life satisfaction in Malaysian adolescents

BackgroundLittle is known on the prospective associations between an empirically derived dietary pattern (DP) and life satisfaction among adolescents. This PUTRA-Adol follow-up study aimed to assess the prospective associations between the empirically derived DP and life satisfaction during adolescence.MethodsA total of 585 and 262 adolescents participated in the baseline PUTRA-Adol study in 2016 and PUTRA-Adol follow-up study in 2019–2020, respectively. These adolescents were recruited from three southern states in peninsular Malaysia, namely Negeri Sembilan, Melaka and Johor. Dietary assessments were estimated using a validated food frequency questionnaire (FFQ) while a Multidimensional Students’ Life Satisfaction Scale (MSLSS) was used to measure life satisfaction at baseline in 2016 as well as at follow-up in 2019–2020. A DP characterised by foods high in free sugar and energy dense was identified using reduced rank regression (RRR), cross-sectionally at baseline and was reported elsewhere. Similar RRR analysis was used to find a DP that best explained the variation in response variables linked to poorer life satisfaction, including dietary energy density (DED), fiber density, and percentage of energy from total fat and sugar at the PUTRA-Adol follow-up study. Prospective relationship between adherence to the identified DPs and overall life satisfaction scores as well as its domains between 2016 and 2019–2020 were evaluated using generalized estimating equation models (GEE).ResultsA DP characterized by high intakes of percentage energy from sugar, fibre and low in DED and percentage energy from total fat was identified at the 2019–2020 follow-up. The identified DP explained 11% of total variations in the response variables and was characterized by high intakes of sweets, sugar sweetened beverages (SSB) and fruits. Female adolescents [67.6(8.9)] had a mean (SD) of life satisfaction that was higher than male adolescents [67.5(10.8)] p < 0.05 in 2019–2020. Prospective analysis found a significant positive association between the identified DP and school domain, in male adolescents (β = 0.117; 95% CI 0.001, 0.234) and an inverse relationship between the DP z-score and self-domain in all adolescents (β = − 0.060; 95% CI − 0.115, − 0.005) from 2016 to 2019–2020.ConclusionsAn increasing score for the predominant ‘High sugar and High fibre’ DP was prospectively associated with increasing life satisfaction score for the school domain in male adolescents and decreasing score for self-domain in both male and females during adolescence. A lifestyle intervention targeting reduced dietary intakes, particularly sugar, may improve life satisfaction in adolescents and promote healthier future without compromising dietary intakes for chronic disease prevention later in life.

Decomposition of HIV Knowledge In Urban-Rural Areas In Indonesia

HIV/AIDS remains a public health crisis, HIV/AIDS remains a public health crisis, especially among male adolescents in Indonesia. This urgency stems from the rapid increase in cases among adolescents, who often lack adequate access to education and prevention resources. If left unaddressed, the epidemic could continue to spread among younger populations, leading to long-term social and economic consequences. Despite the crucial role of HIV knowledge in prevention, disparities exist between rural and urban areas. This study examines these disparities, identifying factors influencing HIV knowledge. This cross-sectional study employed a total of 10,943 male adolescents enrolled in a survey called Indonesia Demographic Health Survey (IDHS) 2017. To address those disparities, a stratification chi-square based on place of residence was employed. We also employed a multivariate decomposition analysis to examine which variables account for most gaps. Results found that only 15% of adolescents were knowledgeable (9.5% in urban and 5.5% in rural areas). Bivariate Analysis showed that education level and HIV test awareness were associated in both areas ( p-value &lt; 0.05), while wealth quintile and internet use were associated in urban areas only ( p-values &lt; 0.05). The HIV knowledge gap would decrease by 8% if internet use was equalized, by 11% if HIV testing awareness was equalized, by 17% if educational attainment was equalized, and by 24% if wealth quintiles were equalized. This calls for a multi-sectoral intervention targeting such factors for better HIV outcomes in Indonesia.

Reflective functioning and emotion regulation in adolescents with a history of sexual offending: a comparative study with a non-offending control group

BackgroundSexual offenses encompass a diverse array of behaviors across various contexts, affecting numerous individuals. Despite the prevalence of sexual offending among adolescents, there is still a limited understanding of this population. To contribute further to the literature in this field, the present study was conducted to compare a group of male adolescents convicted of sexual offenses with a control group in terms of reflective functioning (RF), emotion regulation (ER) strategies, and emotion dysregulation (ED).Methods60 male adolescents aged 12 to 18 years (M = 16.90; SD = 0.97) who had been convicted of at least one serious sexual offense were recruited from male adolescents referred by juvenile courts to the Legal Medicine Organization in Mashhad, Iran, and compared with a control group of non-offending adolescents consisting of 60 male adolescents aged 12 to 18 years (M = 16.97; SD = 0.82) who were attending school. The groups were matched on age and education level.ResultsA comparison between these two groups revealed that adolescents with a history of sexual offending exhibited poorer RF capacity, greater use of suppression as an ER strategy, and higher scores in all ED domains (p’s < 0.001) except non-acceptance of emotional responses compared with the control group.ConclusionsResults suggest that RF, ER strategies, and ED need to be considered as important psychological factors in understanding and treating adolescents with a history of sexual offending.

Mediating attentional control between depression and problematic Internet use in female adolescents: the role of attentional focusing and shifting.

Female adolescents are more prone to depression compared with male adolescents, and depression is often associated with poor attentional control and problematic internet use (PIU). Attentional control includes both focusing and shifting functions. Focusing refers to the ability to direct attention to a task despite distractions. Shifting refers to the ability to flexibly switch attention between different tasks. This study examines the mediating role of attentional focusing and shifting between depression and PIU. Female high school and college students (n = 476) in Taiwan participated in a survey administered at three time points over a seven-month period. The single- and two- mediator models examined their joint mediation effects. The results showed that the direct effect of depression on PIU was significant. The indirect effects also showed that attentional focusing was a negative partial mediator in the relationship between depression and PIU, while attentional shifting was not one. Informed by attentional theory and digital emotion regulation, addressing depression to mitigate its negative impact on attentional control and negative emotions is crucial. The potential impact, whether harmful or beneficial, of adolescents carefully selecting their online activities to reduce the risk of PIU remains contentious. Given the focus on Taiwanese adolescent girls during the COVID-19 pandemic, further research is needed to extend the applicability of the theory to other periods without being affected by COVID-19.
