Excess weight has been associated with numerous psychological problems, including depression and anxiety. This study examined the impact of intentional weight loss on the psychological well-being of adults participating in three clinical weight loss interventions.
This population consisted of 588 overweight or obese individuals randomized into one of three weight loss interventions of incremental intensity for 12 months. Psychological well-being was measured at baseline and 6, and 12 months using the Psychological Well-Being Index.
Mean weight loss was 5.0 pounds at 12 months. Weight change at 12 months was associated with higher overall psychological well-being (r = -.20, p < .001), lower levels of anxiety (r = -.16, p = .001) and depression (r = -.13, p = .004), and higher positive well-being (r = -.19, p < .001), self-control (r = -.13, p = .004), and vitality (r = -.22, p < .001). Vitality was found to be the best predictor of weight change at 12 months (p < .001).
Weight loss was associated with positive changes in psychological well-being. Increased vitality contributed the largest percentage of variance to this change.
超重与许多心理问题有关,包括抑郁和焦虑。本研究考察了在三个临床减肥干预中,有意减肥对成年人心理健康的影响。
该人群由 588 名超重或肥胖个体组成,他们被随机分为三个减肥干预组中的一个,干预强度逐渐增加,持续 12 个月。使用心理幸福感指数在基线和 6 个月、12 个月测量心理健康状况。
12 个月时的平均体重减轻了 5.0 磅。12 个月时的体重变化与整体心理健康水平的提高(r = -.20,p <.001)、焦虑水平的降低(r = -.16,p =.001)和抑郁水平的降低(r = -.13,p =.004)、积极幸福感(r = -.19,p <.001)、自我控制(r = -.13,p =.004)和活力(r = -.22,p <.001)呈正相关。活力被发现是 12 个月时体重变化的最佳预测因素(p <.001)。
体重减轻与心理健康的积极变化有关。活力的增加对这种变化的贡献最大。
