BACKGROUND:Stressful life events in adolescents have been found to be longitudinally associated with higher anxiety sensitivity (AS). A question that has not been addressed is whether AS in adolescence is associated with different childhood adversity exposures. METHODS:School attending adolescents (n=1149) completed measures of anxiety sensitivity (CASI), trait anxiety (STAI-T), childhood trauma (CTQ), depression (CES-DC), alcohol (AUDIT) and drug use (DUDIT), and resilience (CD-RISC) and coping orientation (A-COPE). RESULTS:There was no significant gender difference in childhood trauma exposure, resilience levels or coping orientation. Gender differences were evident in terms of AS, trait anxiety, depression, alcohol and drug use. Depression, trait anxiety and alcohol use mediated the relationship between the amount of childhood trauma and AS and played a role in the relationship between certain childhood trauma types and AS. Neither resilience nor coping orientation had a moderating effect on the relationship between the amount of childhood trauma and AS. LIMITATIONS:Cross-sectional study, over- or under-reporting of data due to use of self-report instruments, and use of a retrospective measure of childhood trauma (CTQ) that is subject to recall bias. CONCLUSIONS:Girls are at greater risk than boys for early onset anxiety disorders as girls have higher rates of AS, trait anxiety and depression despite the same rates of childhood trauma, coping orientation and resilience. Our findings, in the context of childhood trauma, underscore the influence of depression, trait anxiety and alcohol use as risk factors for the development of AS in youth.

BACKGROUND:Physical inactivity during adolescence and youth has been considered as potential risk factor for future mental health problems. The present study was conducted with the aim to examine whether an association exists between leisure-time physical activity (PA) and depression among the youth of Kangra district, studying in professional or degree colleges. METHODOLOGY:A cross-sectional study was conducted among the students of Medical College (MC), Central University (CU) and Industrial Training Institute (ITI) of Kangra district. 370 adolescents and youth of age <25 years, who consented to participate, were recruited. The sample size was divided into three parts among all the three institutes. Only one question regarding leisure time PA (LTPA) was asked, as to how many hours spent in the last week; and Center for Epidemiologic Studies Depression Scale for Children (CES-DC) was used. RESULTS:There were 124 participants from ITI, 126 from CU and 120 from MC. The mean score of CES-DC was highest among CU students 22.7 (±11.0) and lowest among MC students; 13.6 (±9.2). Low LTPA (<4 h) was significantly associated with higher depressive symptoms among all students (odds ratio [95% confidence interval]; 3.34 [1.41-7.92]). CONCLUSION:LTPA was associated with lower rates of depression.

Background:Mental health problems among youth have increased in Sweden in recent decades, as has competition in higher education and the labour market. It is unknown whether the increasing emphasis put on educational achievement might negatively affect adolescents' mental health. We aimed to investigate the relationship between adolescents' academic aspirations and expectations and the risk of mental health problems. Methods:We studied 3343 Swedish 7th grade adolescents (age 13), who participated in the first two waves of the KUPOL longitudinal study; participants answered a questionnaire encompassing the five-item Future Aspirations and Goals (FG) subscale of the Student Engagement Instrument, two questions about their own academic aspirations and expectations and two mental health instruments: the Center for Epidemiological studies for Children (CES-DC) (α=.90) and the Strengths and Difficulties Questionnaire (SDQ) (α=.78). The association between aspirations and expectations at baseline and mental health at follow-up was analysed using logistic regression models adjusting for baseline mental health, socio-demographic and family factors. Results:The FG subscale was inversely and linearly associated with the odds of high CES-DC score [adjusted OR (odds ratio) 0.71, 95% CI (confidence interval): 0.59-0.86], total Strengths and Difficulties Questionnaire score (OR 0.59, 95% CI 0.49-0.71), and its internalizing (OR 0.70, 95% CI 0.59-0.84) and externalizing problems scores (OR 0.58, 95% CI 0.48-0.71). Conclusions:Adolescents with high individual academic aspirations have less mental health problems at 1-year follow-up. Future studies should investigate whether interventions aimed at increasing aspirations and engagement in school may prevent mental health problems in adolescence.

BACKGROUND:There is evidence that mental health problems are increasing and substance use behaviours are decreasing. This paper aimed to investigate recent trends in mental ill health and health-related behaviours in two cohorts of UK adolescents in 2005 and 2015. METHODS:Prevalences in mental health (depressive symptoms, self-harm, anti-social behaviours, parent-reported difficulties) and health-related behaviours (substance use, weight, weight perception, sleep, sexual intercourse) were examined at age 14 in two UK birth cohorts; Avon Longitudinal Study of Parents and Children (ALSPAC, N = 5627, born 1991-92) and Millennium Cohort Study (MCS, N = 11 318, born 2000-02). Prevalences and trend estimates are presented unadjusted and using propensity score matching and entropy balancing to account for differences between samples. RESULTS:Depressive symptoms (9% to 14.8%) and self-harm (11.8% to 14.4%) were higher in 2015 compared with 2005. Parent-reported emotional difficulties, conduct problems, hyperactivity and peer problems were higher in 2015 compared with 2005 (5.7-8.9% to 9.7-17.7%). Conversely, substance use (tried smoking, 9.2% to 2.9%; tried alcohol, 52.1% to 43.5%, cannabis, 4.6% to 3.9%), sexual activity (2% to 0.9%) and anti-social behaviours (6.2-40.1% to 1.6-27.7%) were less common or no different. Adolescents in 2015 were spending less time sleeping (<8 h 5.7% to 11.5%), had higher body mass index (BMI) (obese, 3.8% to 7.3%) and a greater proportion perceived themselves as overweight (26.5% to 32.9%). The findings should be interpreted bearing in mind limitations in ability to adequately harmonize certain variables and account for differences in attrition rates and generalizability of the two cohorts. CONCLUSIONS:Given health-related behaviours are often cited as risk factors for poor mental health, our findings suggest relationships between these factors might be more complex and dynamic in nature than currently understood. Substantial increases in mental health difficulties, BMI and poor sleep-related behaviours highlight an increasing public health challenge.
