The relationship between stress and health care use: an investigation of the buffering roles of personality, social support and exercise.

The main and interactive effects of social support, physical exercise, and personal hardiness on objective measures of health were investigated using a longitudinal research design. Data were collected from 192 working adults. Results showed main effects for hardiness and exercise on the dependent variables of health care costs and the number of health insurance claims filed. Hardiness appeared to be associated with fewer health problems. Contrary to prediction, those who exercised more appeared to have greater health care use. Three-way interactions suggested that health care use was lowest for those high in all three resistance resources: exercise: hardiness: and social support. But, the converse of this reasoning, that absence of these resources is associated with higher levels of illness, was not entirely supported. The interactions suggested that hardiness in the absence of exercise and social support was associated with the highest health care costs. The highest number of claims was apparent for those exhibiting hardiness and exercise. Thus, the presence of exercise, hardiness, and social support seemed to decrease health care use, but the factors contributing to greater health costs and claims were more complicated to interpret.
