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.
这项调查试图在497名体重正常和肥胖的成年人样本中确定体重波动的心理关联因素，这些成年人参与了一项前瞻性自然史研究。受试者按性别、肥胖程度和年龄分层，并根据他们在1年期间的体重变化分为体重维持者、体重增加者或体重减轻者。根据既往自我报告，受试者进一步分为体重波动者或非体重波动者。无论体重如何，非体重波动者报告的总体幸福感显著更高，饮食自我效能感更强，压力更低。与体重增加者相比，体重维持者在与负面影响相关的饮食自我效能感方面更有利。结果表明，体重波动与正常体重和肥胖个体的负面心理特征密切相关。未来的研究应关注体重波动的评估和治疗以及体重维持，而不论体重状况如何。
