Abstract

Background: Behavioral obesity treatments are typically unable to facilitate meaningful weight loss beyond the short term. Implications of malleable psychosocial factors are unclear, which limits behavioral intervention contents. The current aim was to inform obesity treatments to improve their foci on psychosocial factors leading to resilient behavioral changes and maintained weight loss.

Method: Based on pre-planned analyses, women participating in a community-based obesity treatment emphasizing self-regulation and exercise, and who lost at least 3% of their initial weight (N = 89), were measured on eating-related self-efficacy, negative mood, emotional eating, body satisfaction, and self-regulating eating at baseline, Month 3, and Month 6; and on weight change over 12 months.

Results: From baseline to Month 6, there was a significant overall improvement in each psychosocial variable. In separate multiple regression equations, scores at (1) Month 6, (2) change from baseline to Month 6, and (3) change from Month 3 to Month 6 were entered as predictors of maintained weight loss from Month 6 to Month 12. Using a backward elimination process, only negative mood was retained in the final Month 6 model, and significantly predicted maintained weight loss (R2adjusted = .03, p = .050). Changes in self-efficacy, mood, emotional eating, and self-regulation were retained in the final baseline to Month 6 model, and significantly predicted weight loss maintained over 12 months (R2adjusted = .30, p < .001).

Conclusion: Findings add to research on obesity treatment development by suggesting an enhanced focus on facilitating changes in self-efficacy, mood, emotional eating, and self-regulation may enhance maintenance of lost weight (or increase weight loss).

女性持续减肥的社会心理预测因素:为肥胖症行为治疗重点提供依据。
背景:行为性肥胖治疗通常无法在短期内促进有意义的体重减轻。可塑性心理社会因素的影响尚不明确,这限制了行为干预的内容。目前的目的是为肥胖症治疗提供信息,以改善其对心理社会因素的关注,从而实现有弹性的行为改变和持续的体重减轻:根据预先计划的分析,在基线、第3个月和第6个月对参与社区肥胖症治疗、强调自我调节和运动、体重至少减轻3%的女性(N = 89)进行了饮食相关自我效能、负面情绪、情绪化饮食、身体满意度和自我调节饮食的测量,以及12个月内体重变化的测量:从基线到第 6 个月,每个社会心理变量都有显著的整体改善。在单独的多元回归方程中,(1) 第 6 个月的得分、(2) 从基线到第 6 个月的变化以及 (3) 从第 3 个月到第 6 个月的变化被作为第 6 个月到第 12 个月体重持续下降的预测因素。通过逆向排除法,最终的第 6 个月模型中只保留了消极情绪,并且显著预测了体重的持续下降(R2 调整后 = 0.03,p = 0.050)。从基线到第 6 个月的最终模型中保留了自我效能、情绪、情绪化进食和自我调节方面的变化,并能显著预测体重在 12 个月内是否能保持下降(R2 调整值 = .30,p 结论:研究结果为肥胖治疗研究增添了新的内容:研究结果表明,加强对促进自我效能感、情绪、情绪化饮食和自我调节变化的关注,可能会提高体重减轻的维持率(或增加体重减轻),从而为肥胖症治疗发展研究增添了新的内容。

期刊介绍: The International Journal of Behavioral Medicine (IJBM) is the official scientific journal of the International Society for Behavioral Medicine (ISBM). IJBM seeks to present the best theoretically-driven, evidence-based work in the field of behavioral medicine from around the globe. IJBM embraces multiple theoretical perspectives, research methodologies, groups of interest, and levels of analysis. The journal is interested in research across the broad spectrum of behavioral medicine, including health-behavior relationships, the prevention of illness and the promotion of health, the effects of illness on the self and others, the effectiveness of novel interventions, identification of biobehavioral mechanisms, and the influence of social factors on health. We welcome experimental, non-experimental, quantitative, qualitative, and mixed-methods studies as well as implementation and dissemination research, integrative reviews, and meta-analyses.
