Social supports and stress as predictors of illness.

The incidence and pattern of self-reported illness were studied over a six-month period in panels of 292 women and 188 men categorized by their experience of stressful life changes and their perceived supportive relationships. Men and women with more than average stressful changes had a risk of illness 1.6 and 1.8 times that reported by those with below-average changes. Analysis of the interaction of stressful changes with social supports showed that women with a combination of high changes and low supports experienced 2.5 times the rate of illness as those with low changes and high supports. This interaction was not found for men. A monthly rating of perceived life stress was correlated with subsequently recalled life changes for both men and women. The findings for women are consistent with the hypothesis that the interaction of stress with degree of social support is an important predictor of illness experience.
