This study examines the relationship between the demands of providing care to a spouse with dementia and caregiver health behaviors, specifically exercise, sleep patterns, weight maintenance, smoking, and alcohol consumption. Structural equation modeling was used to test a model predicting health behavior change from personal and environmental characteristics, perceived stress, social support, and depressive symptoms in a sample of 233 spouse caregivers of dementia patients and to examine gender differences in these relationships. Results support the hypothesis that caregiving negatively influences health behaviors. Among both women and men, health behavior change is directly influenced by depressive symptoms and objective burden. In addition, depressive symptoms mediate the effects of self-efficacy and objective burden on health behavior change. These results support the notion that health behavior change may represent one mechanism by which caregiving stress leads to adverse health outcomes.
