目的对于已婚夫妇来说，当配偶中的一方参与减肥治疗时，未接受治疗的配偶也可以经历减肥。这项研究在一个全国性的体重管理计划中检验了这种连锁反应。方法将130名二元组随机分为慧俪轻体(WW；n=65)和自我指导对照组(SG；n=65)，并在0、3和6个月时进行评估。纳入标准是年龄25岁，体重指数27到40公斤/米(2)(未经治疗的配偶为25公斤/米(2))，以及没有减肥禁忌症。WW参与者可以免费使用6个月的面对面会议和在线工具。SG参与者收到了一份减肥讲义。结果未治疗的配偶在3个月(体重=-1.52.9 kg；SG=-1.1+/-3.3 kg)和6个月(WW=-2.2+/-4.2 kg；SG=-1.9+/-3.6 kg)时体重下降，但不同情况下体重下降没有差异。总体而言，32.0%的未经治疗的配偶在6个月后体重下降了3%。夫妻间基线体重显著相关(r=0.26；P
ObjectiveFor married couples, when one spouse participates in weight loss treatment, the untreated spouse can also experience weight loss. This study examined this ripple effect in a nationally available weight management program.MethodsOne hundred thirty dyads were randomized to Weight Watchers (WW; n=65) or to a self-guided control group (SG; n=65) and assessed at 0, 3, and 6 months. Inclusion criteria were age25 years, BMI 27 to 40 kg/m(2) (25kg/m(2) for untreated spouses), and no weight loss contraindications. WW participants received 6 months of free access to in-person meetings and online tools. SG participants received a weight loss handout. Spouses did not receive treatment.ResultsUntreated spouses lost weight at 3 months (WW=-1.52.9 kg; SG=-1.1 +/- 3.3 kg) and 6 months (WW=-2.2 +/- 4.2 kg; SG=-1.9 +/- 3.6 kg), but weight losses did not differ by condition. Overall, 32.0% of untreated spouses lost3% of initial body weight by 6 months. Baseline weight was significantly correlated within couples (r=0.26; P
