To examine changes in obesity-related attitudes in a sample of obese women who participated in either dieting or non-dieting interventions.
A total of 123 obese women were randomly assigned to one of three weight control programs: meal replacement diet, balanced deficit diet, or a non-dieting program. (The first two groups were combined as a single dieting condition.) Participants completed questionnaires (at baseline, Week 20, and Week 40) to assess beliefs and attitudes about obesity, along with measures of self-esteem, depression, and body image.
At Weeks 20 and 40, participants in the non-dieting condition reported significantly less negativity about obesity than those in the dieting group. Women in the dieting condition did not report an increase in negative attitudes toward obesity, despite losing significantly more weight than non-dieting participants. Both groups experienced improvements in self-esteem, body image, and depressive symptoms. Improvement in self-esteem was associated with a reduction in negativity about obesity and with improvements in body image.
The non-dieting program produced greater reductions in negative attitudes toward obesity than the dieting intervention. Dieting (with successful weight loss), however, did not result in greater negativity toward obesity. Non-dieting programs seem to be useful in obese women for improving self-esteem, body image, and internalized negative attitudes about obesity.
研究参与节食或非节食干预的肥胖女性样本中与肥胖相关态度的变化。
总共123名肥胖女性被随机分配到三个体重控制项目之一:代餐饮食、均衡热量赤字饮食或非节食项目。(前两组合并为单一节食条件。)参与者在基线、第20周和第40周完成问卷,以评估对肥胖的信念和态度,同时测量自尊、抑郁和身体意象。
在第20周和第40周,非节食组参与者对肥胖的负面评价明显少于节食组。节食组女性尽管比非节食参与者减重更多,但并未报告对肥胖的负面态度增加。两组的自尊、身体意象和抑郁症状均有所改善。自尊的改善与对肥胖负面评价的减少以及身体意象的改善有关。
非节食项目比节食干预对肥胖的负面态度减少得更多。然而,节食(成功减重)并未导致对肥胖的更多负面评价。非节食项目似乎对肥胖女性改善自尊、身体意象和内化的肥胖负面态度有用。
