Psychological correlates of weight fluctuation

Abstract

This investigation attempted to determine psychological correlates of weight fluctuation in a sample of 497 normal weight and obese adults who were enrolled in a prospective, natural history study. Subjects were stratified by gender, obesity, and age and classified as weight maintainers, gainers, or losers based on their changes in weight over a 1-year period. Subjects were further classified as either weight fluctuators or nonfluctuators based on historical self-report. Nonfluctuators reported significantly higher general well-being, greater eating self-efficacy, and lower stress than weight fluctuators, regardless of body weight. Weight maintainers had more favorable eating self-efficacy related to negative affect than weight gainers. Results suggest that weight fluctuation is strongly associated with negative psychological attributes in both normal weight and obese individuals. Future research should focus on the assessment and treatment of weight fluctuation and on weight maintenance, irrespective of weight status.
