Mortality in adults aged 26-54 years related to socioeconomic conditions in childhood and adulthood: post war birth cohort study.

OBJECTIVE To examine premature mortality in adults in relation to socioeconomic conditions in childhood and adulthood. DESIGN Nationally representative birth cohort study with prospective information on socioeconomic conditions. SETTING England, Scotland, and Wales. STUDY MEMBERS: 2132 women and 2322 men born in March 1946 and followed until age 55 years. MAIN OUTCOME MEASURES Deaths between 26 and 54 years of age notified by the NHS central register. RESULTS Study members whose father's occupation was manual at age 4, or who lived in the worst housing, or who received the poorest care in childhood had double the death rate during adulthood of those living in the best socioeconomic conditions. All indicators of socioeconomic disadvantage at age 26 years, particularly lack of home ownership, were associated with a higher death rate. Manual origins and poor care in childhood remained associated with mortality even after adjusting for social class in adulthood or home ownership. The hazard ratio was 2.6 (95% confidence interval 1.5 to 4.4) for those living in manual households as children and as adults compared with those living in non-manual households at both life stages. The hazard ratio for those from manual origins who did not own their own home at age 26 years was 4.9 (2.3 to 10.5) compared with those from non-manual origins who were home owners. CONCLUSIONS Socioeconomic conditions in childhood as well as early adulthood have strongly influenced the survival of British people born in the immediate post war era.
