Purpose
To investigate the association of employment status with CHD and ischemic stroke among middle-aged women.
Methods
Proportional hazards regression was used to assess the association of employment status, incident CHD, and incident ischemic stroke among 7,058 women, aged 45-64 years at baseline (1987-89), from the Atherosclerosis Risk in Communities Study.
Results
After adjusting for age and race-field center, women employed outside the home had a decreased risk of CHD (hazard ratio (HR) =0.70, 95% confidence interval (95% CI) =0.56, 0.86) and ischemic stroke (HR=0.62, 95% CI=0.47, 0.84) compared to homemakers. Differences in cardiovascular disease risk factors partially accounted for the association of employment status and CHD (HR=0.79, 95% CI=0.63, 0.99) and stroke (HR=0.79, 95% CI=0.58, 1.08). Also, modest differences were noted when the results were stratified by education, with employed women having a lower risk of CHD (HR=0.65, 95% CI=0.45, 0.93) than homemakers among those with less than a high school education.
Conclusions
Women employed outside of the home had a lower risk of CHD and stroke compared to homemakers and for CHD, this association was stronger among women with less than a high school education. These findings suggest additional research into the varied occupational experiences of women, socioeconomic status, and health is warranted.
