Objective: To determine whether there is a relationship between baseline le
vels of social support and women's health behaviors. Methods: Baseline surv
eys for 859 women assessed smoking, diet (fat, fruit, and vegetable consump
tion), physical activity, breast and cervical cancer screening, and levels
of social support. Results Women had substantial social networks and a high
level of interaction with their coworkers. Social support was associated w
ith physical activity, fruit and vegetable intake, and cervical cancer scre
ening. Conclusion: Findings suggest that work-site health-promotion program
s for women could benefit from intervening at the social-network level, esp
ecially for some health behaviors.
