title: Weight changes in caregivers of Alzheimer's care recipients: psychobehavioral predictors.
abstract: Relationships of changes in body mass index (BMI) were examined with changes in psychobehavioral variables in spouse caregivers of individuals with Alzheimer's disease (n = 81) and matched spouses of controls (n = 86). Men caregivers had significantly greater BMI and obesity than men controls at both times. Over 15-18 months, women caregivers gained significantly more weight than did women controls. A trend for greater obesity occurred in women caregivers than in women controls at follow-up. Although weight gain was not related to psychobehavioral variables in controls, in men caregivers decreased perceived control and increased fat intake explained significant variance in weight gain. In women caregivers, increased anger control and increased calories explained weight gain. Such caregivers may be at risk for health problems.
