We test whether adverse childhood experiences - exposure to parental maltreatment and its indirect effect on health - are associated with age 30 personality traits. We use rich longitudinal data from a large, representative cohort of young US Americans and exploit differences across siblings to control for the confounding influences of shared environmental and genetic factors. We find that maltreatment experiences are significantly and robustly associated with neuroticism, conscientiousness, and openness to experience, but not with agreeableness and extraversion. High levels of neuroticism are linked to sexual abuse and neglect; low levels of conscientiousness and openness to experience are linked to parental neglect. The associations are partially explained by the indirect effects of maltreatment on adolescence physical and mental health. Maltreatment experiences, in combination with their health effects, explain a substantial fraction of the relationship between adulthood conscientiousness and earnings or human capital. Our findings provide a possible explanation for why personality traits are important predictors of adulthood labor market outcomes.

Background: Although positive childhood experiences (PCEs) have been reported to be crucial for healthy development and better mental and physical health outcomes, their epidemiology and relationship with adverse childhood experiences (ACE) exposure in low and middle-income countries, including India remain underexplored.
Aims: The present study aimed to ascertain the prevalence and predictors of PCE exposure and understand the relationship between PCE and ACE exposure among young adults in Delhi-NCR, India.
Methods: The present cross-sectional study involved a total of 1,573 young adults (18-25 years) of both sexes (69.

Central precocious puberty (CPP) is an endocrine disorder in children caused by the early activation of the hypothalamic-pituitary-gonadal axis (HPGA), leading to elevated gonadotropin-releasing hormone (GnRH), which triggers the development of gonads and the secretion of sex hormones. This eventually results in the development of internal and external genitalia and secondary sexual characteristics. CPP significantly affects the physical and mental health of children and may increase the risk of various adult diseases.

Background: It has been well-established that the allostatic load (AL) index, a cumulative score of multi-system dysregulation in response to chronic stress, is significantly increased at the time of a psychiatric diagnosis. However, no studies have investigated if there is an association between the AL index in childhood and the later development of mental health symptoms in young adults.
Methods: Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population cohort from Bristol, United Kingdom, we investigated the AL index at age 9 years and the risks for mental health symptoms at age 24 years.
