Summary: The study found that exposure to multiple types of early childhood adversity does not increase the risk of self-harm through early pubertal timing, but both childhood adversity and early puberty are risk factors for later self-harm. Identification of mechanisms linking childhood adversity and later self-harm is needed for interventions to be effective.

Summary: This study suggests that early childhood lead exposure may have a detrimental influence on early adolescent autonomic responses to acute stress, which holds implications for cardiovascular health and overall growth and development. The association between lead exposure and physiological stress response warrants further investigation to better understand the underlying mechanisms and potential health effects.

Summary: The study found that autistic traits and ASD diagnoses in childhood were associated with hypomania in adolescence. Genetic influences shared with autistic traits in childhood explained 6-9% of the variance in adolescent hypomania. The results suggest a genetic link between autistic traits and hypomania in adolescence, contributing to the understanding of genetic factors associated with ASDs and psychiatric outcomes.

Summary: This study aimed to explore the association between adverse childhood experiences (ACEs) and the timing and frequency of cannabis use in adolescence. The findings showed that individuals with 4 or more ACEs, particularly those with parental substance use or abuse, were at a higher risk of problematic adolescent cannabis use. Therefore, reducing ACEs may help reduce cannabis use among adolescents.

Summary: Adolescent depression and anxiety are major mental health concerns, with adverse childhood experiences (ACEs) such as maltreatment and family dysfunction being risk factors, and positive childhood experiences in family, school, and neighborhood acting as protective factors. Positive childhood experiences at family and school are the strongest protective factors against mental health concerns, particularly among at-risk adolescents exposed to ACEs. Early interventions focusing on building positive relationships may benefit adolescent mental health.

Summary: Child homelessness is associated with elevated mental health problems during early adolescence. This study aims to explore the association between child homelessness and internalising and externalising symptom trajectories in early adolescence. The results show that children who experienced homelessness had higher internalising and externalising symptoms compared to their consistently housed peers, especially those who first experienced homelessness in middle childhood and those who experienced recurrent homelessness. There were no changes in symptom trajectories over a 4-year period. Men who experienced homelessness displayed a higher risk of internalising symptoms compared to women and men who did not experience homelessness. Interventions and policies targeting family homelessness may improve mental health among adolescents.

Summary: This study found a subgroup with fluctuating ADHD diagnoses in three cohorts, representing a minority of ADHD cases. The fluctuating ADHD diagnoses may suggest a natural history more akin to relapsing-remitting mood disorders and/or a marked sensitivity to environmental shifts that occur across development.

Summary: This study explored how women varsity athletes high in self-compassion appraise and cope with unexpected stressors surrounding competition. Findings suggest that these athletes draw on past experiences, a balanced perspective toward sport, and logical appraisal patterns when evaluating stressors, and use emotional self-awareness, understanding the experiences of others in sport, utilizing social networks, proactive problem-solving, and directing attention to cope with stressors.

Summary: This study used ontogenetic allometry to identify the optimal body size and shape characteristics associated with physical performance in adolescent basketball players, and investigated the effects of various factors on physical performance development. The results showed that players with a leaner physique performed better in physical performance. Size-adjusted running speed development was independent of body size. Players who matured earlier had better physical fitness. Training data did not significantly affect running speed or lower body explosive strength development. Club characteristics were not significantly associated with any physical performance trajectories.

Summary: Self-compassion has been found to be a protective factor against psychological distress in sport. This scoping review updated previous research and identified new areas of research in self-compassion, including the need for theory development, measurement improvement, exploration of the relationship between self-compassion and performance, and the distinction between self-compassion and mindfulness.

Summary: This study explores the relationship between mental toughness and self-compassion in a sport injury context. The findings suggest that self-compassion is positively correlated with mental toughness, coping resources, and self-esteem, and negatively correlated with self-criticism. Self-compassion is a significant predictor of mental toughness, coping resources, and self-criticism, beyond the effects of self-esteem. Interviews with injured athletes further highlight how self-compassion and mental toughness can work together to help athletes cope with sport injury.

Summary: The aim of this study was to examine the association between chronotype and accelerometer-assessed physical behaviours in a cohort of adolescent girls. The study found that a majority of the girls identified as evening chronotypes, and they spent a large proportion of their day sedentary. Morning chronotypes engaged in less sedentary time and had higher overall physical activity on weekdays. These findings may be important for promoting physical activity in adolescent girls.

Summary: This study investigated the participation and completion of rehabilitation programs by patients with coexisting COPD and CHF, and compared the outcomes. The results showed that patients with COPD and CHF had lower participation in cardiac rehabilitation, but higher participation in pulmonary rehabilitation. Patients with COPD had better performance in the incremental shuttle walk test following rehabilitation compared to patients with COPD+CHF. The improvements in the 6-min walk test, quality of life, and mood state were similar between the two groups, regardless of diagnosis.
