Objective.减肥是降低糖尿病风险的最有效方法。研究的首要任务是确定可能提高减肥成功率的因素，特别是对于那些有糖尿病风险的人。这项分析探讨了自我效能，体重减轻和饮食脂肪摄入量之间的关系，在成年人中有患2型糖尿病的风险。方法.这项试点随机试验旨在比较YMCA工作人员提供的基于组的糖尿病预防计划生活方式干预与92名有糖尿病风险的成年人（BMI ≥ 24 kg/m2，≥ 2个糖尿病风险因素，随机毛细血管血糖为110-199 mg/dl）的单独简短咨询（对照）。自我效能是使用体重效能生活方式问卷来测量的。在基线、6个月和12个月时收集数据。采用配对t检验确定6个月和12个月时自我效能和体重的组内变化。使用拟合模型，我们估计了自我效能的增加与6个月和12个月时体重减轻5%有关。结果自我效能与6个月和12个月时基线体重下降5%相关，但与脂肪摄入量无关。结论这些研究结果表明，重要的是要评估自我效能的水平时，咨询成年人在高风险的糖尿病有关减肥。自我效能的某些方面似乎发挥更大的作用，这取决于减肥的阶段。
Objective. Weight loss is the most effective approach to reducing diabetes risk. It is a research priority to identify factors that may enhance weight loss success, particularly among those at risk for diabetes. This analysis explored the relationships between self-efficacy, weight loss, and dietary fat intake among adults at risk for developing type 2 diabetes. Methods. This pilot, site-randomized trial was designed to compare group-based Diabetes Prevention Program lifestyle intervention delivery by YMCA staff to brief counseling alone (control) in 92 adults at risk for diabetes (BMI ≥ 24 kg/m2, ≥ 2 diabetes risk factors, and a random capillary blood glucose of 110–199 mg/dl). Self-efficacy was measured using the Weight Efficacy Lifestyle questionnaire. Data were collected at baseline, 6 months, and 12 months. A paired t test was used to determine within-group changes in self-efficacy and weight at 6 and 12 months. Using a fitted model, we estimated how much of an increase in self-efficacy was related to a 5% weight reduction at 6 and 12 months. Results. Self-efficacy was associated with a 5% reduction in baseline weight at 6 and 12 months but was not related to fat intake. Conclusion. These findings suggest that it is important to assess the level of self-efficacy when counseling adults at high risk for diabetes about weight loss. Certain aspects of self-efficacy seem to play a greater role, depending on the stage of weight loss.
