Brief summary
This study is a secondary analysis of the UK Millennium Cohort Study (MCS), a longitudinal study of young people led by the Centre for Longitudinal Research. Ethics for the MCS has previously been obtained and detailed below. Data will be obtained from the UK Millennium Cohort Study data custodians at the Centre for Longitudinal Research. Additional ethics approval is not required due to the data being pre-existing and non-identifiable. The aim of this study is to investigate the relationships between mental health during childhood and adolescence as an exposure of interest, and subsequent physical activity, diet, sleep and social media use behaviours at 14 years as outcomes of interest, among a large, nationally representative cohort of young people in the United Kingdom. it is hypothesised that mental health problems early in life and in adolescence will predict sub-optimal lifestyle behaviours in adolescence.
Interventions

Data are pre-exsisting from the UK Millennium Cohort Study and data collection occurred during 2008 and 2015. This is a retrospectively study.
