Developmental relationships between socio-economic disadvantage and mental health across the first 30 years of life.

Understanding of how socio-economic disadvantage experienced over the life course relates to mental health outcomes in young adulthood has been limited by a lack of long-term, prospective studies. Here we address this limitation by drawing on data from a large Australian population cohort study that has followed the development of more than 2,000 Australians (and their families) from infancy to young adulthood since 1983. Associations were examined between prospective assessments of socio-economic position (SEP) from 4-8 months to 27-28 years and mental health problems (depression, anxiety, stress) and competence (civic engagement, emotional maturity, secure intimate relationship) at 27-28 years.
