Objective:
To examine premature mortality in adults
in relation to socioeconomic conditions in childhood and adulthood.
What is already known on this topic
Studies have been generally retrospective, been unrepresentative, used
only one marker of childhood conditions, controlled inadequately for
adult conditions, or not included women What this study adds
Those for whom socioeconomic disadvantage continued into early
adulthood were between three and five times more likely to die than
those in the most advantageous conditions
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.
Associations between socioeconomic conditions in childhood and
mortality in adulthood suggest that risks to survival begin in early
life
The death rate for women and men between 26 and 54 years living in
poor socioeconomic conditions in childhood was double that of those
living in the best conditions
