Socioeconomic differences in weight gain and determinants and consequences of coronary risk factors.
The increasing prevalence of overweight and obesity is a major public health concern in many developed countries.
We aimed to describe socioeconomic differences in change in body mass index (BMI : in kg/m2) from age 25 y, assess possible factors behind these differences, and study whether socioeconomic differences in a variety of coronary risk factors can be accounted for by change in BMI.
The data come from a cohort study of London-based civil servants (Whitehall II), who participated in the first (1985-1988) and third (1991-1993) phases of the study and were 35-55-y old at phase 1 ; altogether there were 5507 men and 2466 women.
Both study phases included a questionnaire and a screening examination.
In men and women, employment grade-the measure of socioeconomic status used in this cohort-was strongly related to BMI gain from age 25 y to phase 3 (25 y apart on average).
The lower the grade the larger the gain in BMI.
Adjustment for health behaviors reduced the grade differences in BMI gain by 20%. A substantial part of the grade differences in diastolic and systolic blood pressure and plasma triacylglycerol concentrations could be accounted for by BMI change from age 25 y. Conclusions : Grade differences in BMI change are evident, but many of the determinants of these differences remain unknown. (...)
