The purpose of this study is to explore gender differences in reasons for losing weight, weight loss methods, and weight loss behaviors prior to and during a weight loss maintenance trial. This is a secondary analysis of data from a 24-month randomized controlled trial comparing Self-Directed or Guided phone-based weight loss maintenance interventions among adults who had intentionally lost ≥10% of their body weight in the year prior to enrollment. Participants reported their weight loss methods and reasons for recently losing weight at baseline. Dietary intake, physical activity, and dietary patterns were assessed at baseline, 12, and 24 months. Participants included 419 adults (18.4% men, age 47.0 ± 10.8, BMI 28.4 ± 5.0). Women were more likely than men to report having used an organized weight loss program during their weight loss (55.9% vs. 24.7%, p < .001) and to report improving personal esteem as a motivator (51.2% vs. 35.1%, p = .01). Men were more likely than women to report eating food from convenience stores at baseline (22.1% vs. 13.2%, p = .05) and throughout the study but otherwise reported similar meal patterns ( ps > .05). Men reported higher energy intake than women while physical activity was similar. Although more men self-directed their initial weight loss and more women utilized organized weight loss programs, behaviors reported during weight loss maintenance were similar. Futures studies are needed to understand if these results generalize to other men who have successfully lost weight and are participants in other weight loss maintenance interventions.
本研究旨在探讨在体重维持试验之前及期间，减肥原因、减肥方法和减肥行为方面的性别差异。这是一项对数据的二次分析，该数据来自一项为期24个月的随机对照试验，该试验比较了在入组前一年有意减重≥10%的成年人中，基于电话的自我指导或指导式体重维持干预措施。参与者在基线时报告了他们的减肥方法和近期减肥的原因。在基线、12个月和24个月时评估饮食摄入、身体活动和饮食模式。参与者包括419名成年人（男性占18.4%，年龄47.0±10.8，BMI 28.4±5.0）。女性比男性更有可能报告在减肥期间使用过有组织的减肥计划（55.9%对24.7%，p<.001），并将提高个人自尊作为动机（51.2%对35.1%，p = .01）。在基线时（22.1%对13.2%，p = .05）以及在整个研究过程中，男性比女性更有可能报告从便利店购买食物，但在其他方面报告的饮食模式相似（p>.05）。男性报告的能量摄入量高于女性，而身体活动情况相似。虽然更多男性自我指导他们最初的减肥，更多女性使用有组织的减肥计划，但在体重维持期间报告的行为相似。需要进一步的研究来了解这些结果是否适用于其他成功减肥并参与其他体重维持干预措施的男性。
