Determinants of Adolescent Social Well-being and Health (DASH)

About the cohort

Start date: 2002-03
Age at recruitment: 11-13
Sample size at recruitment: 6,643
Estimated current sample size: 4,779

DASH is a study of a multi-ethnic adolescent cohort in London which investigates social and biological influences on ethnic differences in health and well-being in adolescence. It will provide important insights into the long term impact of these exposures in adolescence and the patterning of ethnic differences in health in later life.

DASH contains over 6,500 pupils recruited from 51 schools across 10 inner London boroughs. Pupils were aged 11-13 years old at the start of the study in 2003, and were followed up at 2005/06, 2010-13 and 2012/13.

DASH was designed to have a sizeable number of respondents from the major ethnic minority groups. Cultural differences within South Asian groups are well known but very little is known about these issues among those of African origin. In DASH, Black Caribbeans, Nigerians, Ghanaians and other Africans can be identified separately so that differences in health and well-being can be explored.
