Adolescence and the next generation.

Adolescent growth and social development shape the early development of offspring from preconception through to the post-partum period through distinct processes in males and females. At a time of great change in the forces shaping adolescence, including the timing of parenthood, investments in today's adolescents, the largest cohort in human history, will yield great dividends for future generations.

Local exposure to school shootings and youth antidepressant use.

While over 240,000 American students experienced a school shooting in the last two decades, little is known about the impacts of these events on the mental health of surviving youth. Using large-scale prescription data from 2006 to 2015, we examine the effects of 44 school shootings on youth antidepressant use. Our empirical strategy compares the number of antidepressant prescriptions written by providers practicing 0 to 5 miles from a school that experienced a shooting (treatment areas) to the number of prescriptions written by providers practicing 10 to 15 miles away (reference areas), both before and after the shooting. We include month-by-year and school-by-area fixed effects in all specifications, thereby controlling for overall trends in antidepressant use and all time-invariant differences across locations. We find that local exposure to fatal school shootings increases youth antidepressant use by 21.4% in the following 2 y. These effects are smaller in areas with a higher density of mental health providers who focus on behavioral, rather than pharmacological, interventions.

The social gradient in adolescent mental health: mediated or moderated by belief in a just world?

PURPOSE: A social gradient in adolescent mental health exists: adolescents with higher socioeconomic status (SES) have fewer mental health problems than their peers with lower SES. Little is known about whether adolescents' societal beliefs play a role in this social gradient. Belief in a just world (BJW) may be a mediator or moderator of the social gradient in adolescent mental health. METHODS: Using data from 848 adolescents (Mage = 17) in the Netherlands, path analyses examined whether two indicators of BJW (general and personal) mediated or moderated the associations between two indicators of SES (family affluence and perceived family wealth), and four indicators of adolescent mental health problems (emotional symptoms, conduct problems, hyperactivity, and peer problems). RESULTS: Adolescents with lower family affluence and lower perceived family wealth reported more emotional symptoms, and the association between perceived family wealth and emotional symptoms was mediated by lower personal and general BJW. Furthermore, higher personal BJW amplified the negative association between SES and peer problems. CONCLUSION: This study suggests BJW may both mediate and amplify the social gradient in adolescent mental health. Adolescents' beliefs about society may be important to include in research aimed at understanding this social gradient.

Demographic and epidemiological transitions and burden of adolescent healthcare in sub-Saharan Africa: A review.

This review's main objective is to discuss how demographic and epidemiological transitions relate to the burden of adolescent healthcare in sub-Saharan Africa (SSA). The review explicitly discussed the burden of adolescent healthcare, the current African policies on adolescent healthcare, and gaps in the African policies compared with Europe and North America. We also examined how adolescent healthcare policies evolve and documented the recommended essential part of the policy for enhancing its sustainability. The burden of adolescent health is high in SSA with diseases and reproductive health-related problems prevailing among adolescents. However, variations exist in the burden of adolescent healthcare across countries in the region. While some SSA countries are currently undergoing demographic and epidemiological transition processes concerning adolescent health care, the majority are either at an early stage of the transition or yet to commence the process. Policy-makers should consider effective ways to improve adolescents' health in SSA through preventive mechanisms and a multi-dimensional approach.

Association of Family Income With Morbidity and Mortality Among US Lower-Income Children and Adolescents.

Importance: Family income is known to be associated with children's health; the association may be particularly pronounced among lower-income children in the US, who tend to have more limited access to health resources than their higher-income peers. Objective: To investigate the association of family income with claims-based measures of morbidity and mortality among children and adolescents in lower-income families in the US enrolled in Medicaid or the Children's Health Insurance Program. Design, Setting, and Participants: This cross-sectional analysis included 795 000 participants aged 5 to 17 years enrolled in Medicaid (Medicaid Analytic eXtract claims, 2011-2012) living in families with income below 200% of the federal poverty threshold (American Community Survey, 2008-2013). Follow-up ended in December 2021. Exposures: Family income relative to the federal poverty threshold. Main Outcomes and Measures: Record of International Classification of Diseases, Ninth Revision codes for an infection, mental health disorder, injury, asthma, anemia, or substance use disorder and death record within 10 years of observation (Social Security Administration death records through 2021). Results: Among 795 000 individuals in the sample (all statistics weighted: mean [SD] income-to-poverty ratio, 90% [53%]; mean [SD] age, 10.6 [3.9] years; 56% aged 10 to 17 years), 33% had a diagnosed infection, 13% had a mental health disorder, 6% had an injury, 5% had asthma, 2% had anemia, 1% had a substance use disorder, and 0.6% died between 2011 and 2021, with the mean (SD) age at death of 19.8 (4.2) years. For those aged 5 to 9 years, higher family income was associated with lower adjusted prevalence of all outcomes, except mortality: children in families with an additional 100% income relative to the federal poverty threshold had 2.3 (95% CI, 1.8-2.9) percentage points fewer infections, 1.9 (95% CI, 1.5-2.2) percentage points fewer mental health diagnoses, 0.7 (95% CI, 0.5-0.8) percentage points fewer injuries, 0.3 (95% CI, 0.09-0.5) percentage points less asthma, 0.2 (95% CI, 0.08-0.3) percentage points less anemia, and 0.06 (95% CI, 0.03-0.09) percentage points fewer substance use disorder diagnoses. Except for injury and anemia, the associations were more pronounced among those aged 10 to 17 years than those 5 to 9 years (P for interaction <.05). For those aged 10 to 17 years, an additional 100% income relative to the federal poverty threshold was associated with a lower 10-year mortality rate by 0.18 (95% CI, 0.12-0.25) percentage points. Conclusions and Relevance: Among children and adolescents in the US aged 5 to 17 years with family income under 200% of the federal poverty threshold who accessed health care through Medicaid or the Children's Health Insurance Program, higher family income was significantly associated with a lower prevalence of diagnosed infections, mental health disorders, injury, asthma, anemia, and substance use disorders and lower 10-year mortality. Further research is needed to understand whether these associations are causal.

Impact of a Family Economic Intervention (Bridges) on Health Functioning of Adolescents Orphaned by HIV/AIDS: A 5-Year (2012-2017) Cluster Randomized Controlled Trial in Uganda.

Objectives. To investigate the long-term impacts of a family economic intervention on physical, mental, and sexual health of adolescents orphaned by AIDS in Uganda.Methods. Students in grades 5 and 6 from 48 primary schools in Uganda were randomly assigned at the school level (cluster randomization) to 1 of 3 conditions: (1) control (n = 487; 16 schools), (2) Bridges (1:1 savings match rate; n = 396; 16 schools), or (3) Bridges PLUS (2:1 savings match rate; n = 500; 16 schools).Results. At 24 months, compared with participants in the control condition, Bridges and Bridges PLUS participants reported higher physical health scores, lower depressive symptoms, and higher self-concept and self-efficacy. During the same period, Bridges participants reported lower sexual risk-taking intentions compared with the other 2 study conditions. At 48 months, Bridges and Bridges PLUS participants reported better self-rated health, higher savings, and lower food insecurity. During the same period, Bridges PLUS participants reported reduced hopelessness, and greater self-concept and self-efficacy. At 24 and 48 months, Bridges PLUS participants reported higher savings than Bridges participants.Conclusions. Economic interventions targeting families raising adolescents orphaned by AIDS can contribute to long-term positive health and overall well-being of these families.Trial Registration. ClinicalTrials.gov registration no. NCT01447615.

Bullying, social support and adolescents' mental health: Results from a follow-up study.

Aims: The aim of this study was to examine the predictive roles of being bullied and perceived social support in association with adolescents' mental health. Methods: At two time points, September 2016 and April-June 2017, questionnaires were distributed to students between 15 and 21 years of age in four upper-secondary schools in Norway, with a total sample size of 351. Random- and fixed-effects regression models were used to estimate the effects of being bullied and social support on adolescents' mental health. Results: In the random-effects models, being bullied was associated with lower scores on mental well-being and higher scores on anxiety and depression symptoms. Social support from family and friends was associated with higher scores on mental well-being, as well as fewer anxiety and depression symptoms. However, the results from the fixed-effects model, with more realistic assumptions, indicated that being bullied was only associated with more anxiety and depression symptoms, while support from friends was associated with higher scores on mental well-being and fewer anxiety and depression symptoms. Conclusions: Based on the fixed-effects models, being bullied was associated with more anxiety and depression symptoms. However, being bullied was not significantly associated with mental well-being. Social support from family was not significantly associated with either aspects of mental health. Moreover, social support from friends was associated with higher scores on mental well-being and fewer anxiety and depression symptoms. The two sources of social support did not buffer the negative effects of being bullied on either aspect of mental health.

Tampon loss - management among adolescents and adult women.

The widespread use of tampons carries a risk of tampon loss due to imperfect use. We performed a retrospective study including all women attending the emergency room (ER) with the complaint of tampon loss during 2011-2018. Overall, 72 women presented to the ER with a complaint of tampon loss. In 25% (18/72), a lost tampon was found on physical examination. The lost tampon was found in a higher rate among adolescents as compared to older women (4 (80%) vs. 14 (21%), 15.1, p = .01). Time from tampon loss to referral for evaluation was shorter among adolescents as compared to older women (7 ± 3 vs. 21 ± 21 h, p = .007). In most adolescents with a complaint of a lost tampon - it was eventually found on pelvic examination, as opposed to older women, in whom a finding was present in only one-fifth of cases. This highlights the importance of thorough examination of adolescents presenting due to tampon loss. The study protocol was approved by the Sheba Medical Center review board (March 15, 2018), 6345-19-SMC.IMPACT STATEMENTWhat is already known on this subject? Very little is known regarding the distinguished phenomena of tampon loss among adult females.What do the results of this study add? In most adolescents referred due to tampon loss - a tampon was found on pelvic examination, as opposed to older women.What are the implications of these findings for future clinical practice and/or further research? In most adolescents referred due to tampon loss - a tampon will be found on pelvic examination, as opposed to older women, in whom a finding is present in only one-fifth of cases. This highlights the importance of thorough examination of adolescents presenting with a loss of tampon.

Associations of temperament types and gender of early adolescents and teachers with adolescents' school well-being.

This study examined the role of temperament type and gender of adolescents and teachers in adolescents' well-being in school. The sample consisted of 677 Finnish students and 56 classroom teachers. Parents rated adolescent temperament and teachers rated their own temperament in autumn of Grade 6. Self-reports of school well-being among adolescents were obtained in autumn and the fall of Grade 6. The results showed that being a girl and having resilient temperament type predicted higher school well-being. In turn, boys with undercontrolled temperament, who were otherwise at risk for decreased school well-being, particularly benefited from having a female teacher with resilient temperament. Overall, the results suggest that both adolescent temperament type and gender play important roles in adolescents' well-being in school.

Progress in adolescent health and wellbeing: tracking 12 headline indicators for 195 countries and territories, 1990-2016.

BACKGROUND: Rapid demographic, epidemiological, and nutritional transitons have brought a pressing need to track progress in adolescent health. Here, we present country-level estimates of 12 headline indicators from the Lancet Commission on adolescent health and wellbeing, from 1990 to 2016. METHODS: Indicators included those of health outcomes (disability-adjusted life-years [DALYs] due to communicable, maternal, and nutritional diseases; injuries; and non-communicable diseases); health risks (tobacco smoking, binge drinking, overweight, and anaemia); and social determinants of health (adolescent fertility; completion of secondary education; not in education, employment, or training [NEET]; child marriage; and demand for contraception satisfied with modern methods). We drew data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016, International Labour Organisation, household surveys, and the Barro-Lee education dataset. FINDINGS: From 1990 to 2016, remarkable shifts in adolescent health occurred. A decrease in disease burden in many countries has been offset by population growth in countries with the poorest adolescent health profiles. Compared with 1990, an additional 250 million adolescents were living in multi-burden countries in 2016, where they face a heavy and complex burden of disease. The rapidity of nutritional transition is evident from the 324·1 million (18%) of 1·8 billion adolescents globally who were overweight or obese in 2016, an increase of 176·9 million compared with 1990, and the 430·7 million (24%) who had anaemia in 2016, an increase of 74·2 million compared with 1990. Child marriage remains common, with an estimated 66 million women aged 20-24 years married before age 18 years. Although gender-parity in secondary school completion exists globally, prevalence of NEET remains high for young women in multi-burden countries, suggesting few opportunities to enter the workforce in these settings. INTERPRETATION: Although disease burden has fallen in many settings, demographic shifts have heightened global inequalities. Global disease burden has changed little since 1990 and the prevalence of many adolescent health risks have increased. Health, education, and legal systems have not kept pace with shifting adolescent needs and demographic changes. Gender inequity remains a powerful driver of poor adolescent health in many countries.

Design and field methods of the ARISE Network Adolescent Health Study.

The ARISE Network Adolescent Health Study is an exploratory, community-based survey of 8075 adolescents aged 10-19 in 9 communities in 7 countries: Burkina Faso, Eswatini, Ethiopia, Ghana, Nigeria, Tanzania and Uganda. Communities were selected opportunistically and existing population cohorts maintained by health and demographic surveillance systems (HDSSs). The study is intended to serve as a first round of data collection for African adolescent cohorts, with the overarching goal of generating community-based data on health-related behaviours and associated risk factors in adolescents, to identify disease burdens and health intervention opportunities. Household-based sampling frames were used in each community to randomly select eligible adolescents (aged 10-19 years). Data were collected between July 2015 and December 2017. Consenting participants completed face-to-face interviews with trained research assistants using a standardised questionnaire, which covered physical activity, cigarette and tobacco use, substance and drug use, mental health, sexual behaviours and practices, sexually transmitted infections, pregnancy, food security and food diversity, teeth cleaning and hand washing, feelings and friendship, school and home activities, physical attacks and injuries, health care, health status assessment and life satisfaction, as well as media and cell phone use and socio-demographic and economic background characteristics. Results from this multi-community study serve to identify major adolescent health risks and disease burdens, as well as opportunities for interventions and improvements through policy changes.

L'étude ARISE du réseau sur la santé des adolescents est une étude exploratoire de surveillance basée sur la communauté portant sur 8.075 adolescents âgés de 10 à 19 ans dans 9 communautés de 7 pays: Burkina Faso, Eswatini, Ethiopie, Ghana, Nigéria, Tanzanie et Ouganda. Les communautés ont été sélectionnés de manière opportuniste et les cohortes de population existantes maintenues par des systèmes de surveillance de la santé et démographique (SSSD). L'étude est destinée à servir comme premier cycle de collecte de données pour les cohortes d'adolescents africains, dans le but primordial de générer des données communautaires sur les comportements liés à la santé et les facteurs de risque associés chez les adolescents, afin d'identifier la charge de morbidité et les opportunités d'intervention en matière de santé. Des cadres d'échantillonnage basés sur le ménage ont été utilisés dans chaque communauté pour sélectionner au hasard les adolescents admissibles (âgés de 10-19 ans). Les données ont été collectées entre juillet 2015 et décembre 2017. Les participants consentants ont participé à des entretiens de face à face avec des assistants de recherche formés, à l'aide d'un questionnaire standardisé couvrant l'activité physique, l'usage de la cigarette ou la consommation de tabac, l'usage de drogues et autres substances, la santé mentale, les comportements et pratiques sexuels, les infections sexuellement transmissibles, la grossesse, la sécurité et la diversité alimentaire, le nettoyage des dents et le lavage des mains, les sentiments et les amitiés, les activités scolaires et à domicile, les attaques et les blessures physiques, les soins de santé, l'évaluation de l'état de santé et la satisfaction à l'égard de la vie, l'utilisation des médias et du téléphone portable ainsi que les caractéristiques sociodémographiques et économiques. Les résultats de cette étude portant sur plusieurs communautés permettent d'identifier les principaux risques pour la santé des adolescents et les charges de morbidité, ainsi que les opportunités d'interventions et d'amélioration par le biais de changements de politiques.

Longitudinal association between body mass index and physical activity among adolescents with different parental risk: a parallel latent growth curve modeling approach.

BACKGROUND: Data available on the association between physical activity (PA) and body mass index (BMI) in different periods of life is controversial. Using a parallel latent growth curve modeling (LGCM) approach, the current study aimed to investigate the influence of daily PA on adolescents' BMI over a 12 year follow-up, taking into account their parental risk. METHOD: Participants comprised 1323 adolescents (53.5% girls), aged 12-18 years who had participated in the baseline phase of Tehran Lipid and Glucose Study (TLGS) (2001-2003), and were followed for an average period of 12 years. Physical activity, including leisure time and occupational activities, was assessed using the reliable and validated Iranian version of the Modifiable Activity Questionnaire (MAQ). Weight and height were objectively measured in order to calculateBMI.Atwo-step cluster analysis was conducted to classify parents into two high- and low-risk clusters. Parallel LGCM was fitted to estimate cross-sectional, prospective and parallel associations, which assessed the longitudinal association between simultaneous changes in PA and BMI during the study period. Analyses were stratified by gender and parental clusters. RESULTS: A rising trend of BMI per 3 years was observed in boys 1.39 kg.m2(95% CI; 1.32, 1.48) and girls 0.9 kg.m2(95% CI; 0.82, 0.98), as well as in the low risk 1.11 kg.m2(95% CI; 1.03, 1.18) and high-risk 1.12 kg.m2(95% CI; 1.03, 1.22) clusters. Moreover, a positive prospective association between PA at baseline and BMI change over the 12 year follow-up, was observed in adolescents in the low-risk parental cluster 0.27(95% CI; 0.14, 0.41) indicating that higher levels of PA at baseline may lead to greater BMI in adolescents over time. However, examining longitudinal parallel association between simultaneous changes of PA and BMI per 3 years revealed adverse associations for adolescents in the low-risk parental cluster - 0.07 (95% CI; - 0.13, - 0.01) and in boys - 0.06 (95% CI; - 0.11, - 0.01). CONCLUSION: Despite a positive prospective association between BMI and PA at baseline, there was a weak inverse parallel association between these variables over time, particularly in boys and adolescents with low parental risk. These findings imply the potential role of other influential factors indetermining adolescents' weight status which need to be considered in the future plannings.

Intersecting inequalities, gender and adolescent health in Ethiopia.

BACKGROUND: Until recently, global public health initiatives have tended to overlook the ways that social factors shape adolescent health, and particularly how these dynamics affect the specific needs of adolescents in relation to information about puberty, menstruation and sexual health. This article draws on mixed methods data from rural and urban areas of Ethiopia to explore how access to health information and resources - and subsequently health outcomes - for adolescents are mediated by gender and age norms, living in different geographical locations, poverty, disability and migration. METHODS: Data was collected in 2017-2018 for the Gender and Adolescence: Global Evidence (GAGE) mixed-methods longitudinal research baseline in three regions of Ethiopia (Afar, Amhara and Oromia). Quantitative data was collected from over 6800 adolescents and their caregivers, with qualitative data obtained from a sub-sample of 220 adolescents, their families and communities. Adolescent participants shared their experiences of health, illness and nutrition over the previous year; their knowledge and sources of information about sexual and reproductive health and puberty; and their attitudes toward sexual and reproductive health. Regression analysis was used to explore differences by gender, age, rural/urban residence, and disability status, across a set of adolescents' health knowledge and other outcomes in the quantitative data. Intersectional analysis was used in analysing the qualitative data. RESULTS: Analysis suggested that gender inequality intersects with age, disability and rural/urban differences to shape young people's access to information about puberty, with knowledge about this topic particularly lacking amongst younger adolescents in rural areas. Drought and lack of access to clean water exacerbates health challenges for adolescents in rural areas, where a lack of information and absence of access to preventive healthcare services can lead to permanent disability. The research also found that gaps in both school-based and alternative sources of education about puberty and menstruation reinforce stigma and misinformation, especially in rural areas where adolescents have higher school attrition rates. Gendered cultural norms that place high value on marriage and motherhood generate barriers to contraceptive use, particularly in certain rural communities. CONCLUSIONS: As they progress through adolescence, young people's overall health and access to information about their changing bodies is heavily shaped by intersecting social identities. Structural disadvantages such as poverty, distress migration and differential access to healthcare intersect with gender norms to generate further inequalities in adolescent girls' and boys' health outcomes.

Prevalence and determinants of asthma among aboriginal adolescents in Canada.

Objective: The objective of the study was to determine the prevalence and associated risk factors of asthma in Aboriginal adolescents in Canada based on the Canadian Aboriginal Peoples Survey (APS) 2012. Few studies have investigated the prevalence and risk factors of asthma in Aboriginal adolescents in Canada. Methods: Data from the cross-sectional APS 2012 were analyzed to accomplish the objective. Logistic regression analysis was utilized to determine significant risk factors of lifetime diagnosis of asthma among Aboriginal adolescents. The outcome of interest for adolescents was based on the question: "Do you have asthma that have been diagnosed by a health professional?" Individual, environmental, and contextual factors were tested for an association with lifetime diagnosis of asthma among adolescents. Results: The overall prevalence of lifetime diagnosis of asthma was 16.0%. The prevalence of lifetime diagnosis of asthma was 16.8% for adolescent boys and 15.3% for adolescent girls. Based on multivariable logistic regression analysis, the risk factors of lifetime diagnosis of asthma were: age, income, being overweight, smoking inside the home, having one to two children under 18 years in the household, history of bronchitis, living in an urban residence, education, and geographical location. Female sex was reported to have a protective effect on or reduce risk of the prevalence of lifetime diagnosis of asthma compared to the male sex. Conclusions: Lifetime diagnosis of asthma prevalence appears to be lower in Aboriginal adolescent girls than in adolescent boys. Lifetime diagnosis of asthma prevalence in these adolescents is associated with age, income, education, being overweight, smoking inside the home, history of bronchitis, and location of residence, both geographical region and urban residence. The prevalence of lifetime diagnosis of asthma among Aboriginal adolescent is higher compared to the general adolescent population in Canada.

Evaluating the Role of Parental Education and Adolescent Health Problems in Educational Attainment.

This article reconsiders the role of social origin in health selection by examining whether parental education moderates the association between early health and educational attainment and whether health problems mediate the intergenerational transmission of education. We used longitudinal register data on Finns born in 1986-1991 (n = 352,899). We measured the completion of secondary and tertiary education until age 27 and used data on hospital care and medication reimbursements to assess chronic somatic conditions, frequent infections, and mental disorders at ages 10-16. We employed linear probability models to estimate the associations between different types of health problems and educational outcomes and to examine moderation by parental education, both overall in the population and comparing siblings with and without health problems. Finally, we performed a mediation analysis with g-computation to simulate whether a hypothetical eradication of health problems would weaken the association between parental and offspring education. All types of health problems reduced the likelihood of secondary education, but mental disorders were associated with the largest reductions. Among those with secondary education, there was further evidence of selection to tertiary education. High parental education buffered against the negative impact of mental disorders on completing secondary education but exacerbated it in the case of tertiary education. The simulated eradication of health problems slightly reduced disparities by parental education in secondary education (up to 10%) but increased disparities in tertiary education (up to 2%). Adolescent health problems and parental education are strong but chiefly independent predictors of educational attainment.

A composite measure of healthy lifestyle: A study from 38 countries and regions from Europe and North America, from the Health Behavior in School-Aged Children survey.

INTRODUCTION: This study aimed to create a composite measure of a healthy lifestyle for adolescents, and analyze its relationship to sociodemographic factors. METHODS: Data were from the Health Behavior in School-Aged Children 2014 International survey. Participants were 167 021 adolescents (48.2% boys and 51.8 girls), aged 10-16 years, from 38 countries. RESULTS: Five healthy behaviors used in this study included engaging in ≥60 minutes of physical activity every day, daily consumption of fruit and vegetables, spending <2 hours daily immersed in screen-based behaviors, and abstinence from alcohol as well as from tobacco products. Only 1.9% (95% CI: 1.4%, 2.3%) of adolescents had a healthy lifestyle, achieving all five healthy behaviors. In contrast, 4.2% (95% CI: 3.7%, 4.6%) reported none of the healthy behaviors. CONCLUSIONS: Despite the benefits of engaging in physical activity, engaging in low levels of screen-based activity, regular consumption of fruits and vegetables, and abstaining from alcohol and cigarettes, only 2% of adolescents could be classified as having a healthy lifestyle.

Divorce and conversational difficulties with parents: Impact on adolescent health and self-esteem.

Background: Divorce experience (DE) may cause health and self-conceptual problems, but these consequences might also be caused by conflicts and lack of conversational confidence (CC) with one or both parents. We investigated how DE impacted CC and how DE and CC impacted health complaints and self-esteem in a two-year longitudinal cohort study. Methods: The study was performed between 2011 and 2013 among 1225 students in junior high school (aged 11 and 13 years in 2011). We used binary logistic analyses to account for how DE impacted CC, and linear regression analyses to examine how DE and CC impacted on subjective health and self-esteem in 2013. Results: The study revealed that former and recent DEs impacted CC with fathers only. The impact was most evident for the more severe forms of conversational difficulties. DE in itself predicted only self-esteem, and CC with parents mediated this association. CC with both mothers and fathers had strong temporal causal associations with the outcomes two years later. Only CC with fathers impacted changes of the health complaints and self-esteem in full-model residual change analyses. Conclusions: The study proves a sex-specific effect on loss of CC between fathers and children after divorce. The impairment of CC has predictive repercussions on the health and self-conception of adolescents in their middle teenage years. From a public-health perspective, preserving the relation and the confidence between children and their fathers after divorce seems an important task.

Child abuse and physical health: A population-based study on physical health complaints among adolescents and young adults.

Aims: To investigate whether adolescents and young adults with a history of child abuse had more physical health complaints compared to their unexposed peers. We also aimed to estimate associations between different child abuse types with physical health complaints and associations between the number of child abuse types and physical health complaints. Methods: This population-based telephone survey over two waves included 506 adolescents and young adults exposed to child abuse and 504 non-abused peers aged 16-33 years. We applied linear regression analyses to investigate associations between child abuse types and physical health complaints, unadjusted and mutually adjusted for co-occurring abuse, and to investigate how the number of child abuse types associated with physical health complaints. Results: Participants exposed to child abuse reported significantly more physical health complaints. The child abuse types strongly co-occurred. When adjusting for co-occurring child abuse, only sexual and emotional abuse were significantly associated with physical health complaints. Physical health complaints increased with the higher number of child abuse types experienced. Conclusions: Our findings suggest that exposure to abuse, particularly sexual and emotional, during childhood predicts physical health complaints in adolescence and early adulthood. In a public health perspective, early identification of child abuse may be beneficial in preventing physical health complaints later in life.

A systematic literature review of existing conceptualisation and measurement of mental health literacy in adolescent research: current challenges and inconsistencies.

BACKGROUND: With an increased political interest in school-based mental health education, the dominant understanding and measurement of mental health literacy (MHL) in adolescent research should be critically appraised. This systematic literature review aimed to investigate the conceptualisation and measurement of MHL in adolescent research and the extent of methodological homogeneity in the field for meta-analyses. METHODS: Databases (PsycINFO, EMBASE, MEDLINE, ASSIA and ERIC) and grey literature were searched (1997-2017). Included articles used the term 'mental health literacy' and presented self-report data for at least one MHL domain with an adolescent sample (10-19 years). Definitions, methodological and contextual data were extracted and synthesised. RESULTS: Ninety-one articles were identified. There was evidence of conceptual confusion, methodological inconsistency and a lack of measures developed and psychometrically tested with adolescents. The most commonly assessed domains were mental illness stigma and help-seeking beliefs; however, frequency of assessment varied by definition usage and study design. Recognition and knowledge of mental illnesses were assessed more frequently than help-seeking knowledge. A mental-ill health approach continues to dominate the field, with few articles assessing knowledge of mental health promotion. CONCLUSIONS: MHL research with adolescent samples is increasing. Results suggest that a better understanding of what MHL means for this population is needed in order to develop reliable, valid and feasible adolescent measures, and explore mechanisms for change in improving adolescent mental health. We recommend a move away from 'mental disorder literacy' and towards critical 'mental health literacy'. Future MHL research should apply integrated, culturally sensitive models of health literacy that account for life stage and acknowledge the interaction between individuals' ability and social and contextual demands.
