背景 减肥手术有助于显着且持久的体重减轻；然而，结果各不相同。除了生理和技术因素外，减肥效果还取决于行为的改变以维持能量平衡的长期变化。本研究旨在评估能量摄入和体力活动变化的程度和性质，并确定腹腔镜可调节胃束带 (LAGB) 12 个月后与体重减轻百分比 (%WL) 相关的因素。方法 129 名完成减肥手术的候选者（26 名男性/103 名女性，平均年龄 45.2 +/- 11.5，平均体重指数 [BMI] 44.3 +/- 6.8，范围 31.9 至 66.7）完成研究。数据在基线和 12 个月时收集。经过验证的问卷包括维多利亚癌症委员会食物频率问卷、三因素饮食问卷、Short Form-36、Baecke 身体活动问卷和贝克抑郁量表。评估“非饥饿饮食”、“情绪化饮食”和“放牧”的症状。结果平均 %WL 为 20.8 +/- 8.5%，过度体重减轻为 50.0 +/- 20.7 (p < 0.001)。平均总能量摄入量从 9,991 +/- 3,986 kj 减少到 4,077 +/- 1,493 kj (p < 0.001)。平均休闲时间和与运动相关的体力活动得分增加（均 p < 0.001）。回归分析确定基线 BMI（β = 0.241；p = 0.002）、主观饥饿（β = -0.275；p = 0.001）、身体机能（β = 0.309；p < 0.001）和闲暇时间体力活动（β = 0.213；p = 0.010）作为 %WL 的独立预测因子，总 R-2 0.34%。 “非饥饿饮食”和抑郁症状也与较差的 %WL 有关。结论 LAGB 会影响显着的行为改变，并有助于在前 12 个月内大幅减轻体重。然而，采取的行为的变化可能会影响能量平衡和减肥成功。在持续的术后审查和咨询过程中，实现和维持良好的行为应该是一个重要的考虑因素。管理应包括适当的频带调整以控制身体饥饿、优化身体机能和活动以及强化减少能量摄入的策略。
Background Bariatric surgery facilitates substantial and durable weight loss; however, outcomes vary. In addition to physiological and technical factors, weight loss efficacy is dependent on modification of behavior to maintain a long-term change in energy balance. This study aimed to assess the extent and nature of change in energy intake and physical activity and identify factors associated with percentage weight loss (%WL) 12 months after laparoscopic adjustable gastric banding (LAGB).Methods 129 bariatric surgery candidates (26 men/103 women, mean age 45.2 +/- 11.5, mean body mass index [BMI] 44.3 +/- 6.8, range 31.9 to 66.7) completed the study. Data were collected at baseline and 12 months. Validated questionnaires included the Cancer Council Victoria Food Frequency Questionnaire, Three Factor Eating Questionnaire, Short Form-36, Baecke Physical Activity Questionnaire, and Beck Depression Inventory. Symptoms of "non-hungry eating," "emotional eating," and "grazing" were assessed.Results Mean %WL was 20.8 +/- 8.5%, and excess weight loss was 50.0 +/- 20.7 (p < 0.001). Mean total energy intake reduced from 9,991 +/- 3,986 kj to 4,077 +/- 1,493 kj (p < 0.001). Average leisure time and sport-related physical activity scores increased (both p < 0.001). Regression analysis identified baseline BMI (beta = 0.241; p = 0.002), subjective hunger (beta = -0.275; p = 0.001), physical function (beta = 0.309; p < 0.001), and leisure time physical activity (beta = 0.213; p = 0.010) as independent predictors of %WL, total R-2 0.34%. "Non-hungry eating" and symptoms of depression were also related to poorer %WL.Conclusion LAGB affects marked behavior change and facilitates substantial weight loss in the first 12 months. However, variations in adopted behaviors can affect energy balance and weight loss success. Achievement and maintenance of favorable behaviors should be an important consideration during on-going postsurgical review and counseling. Management should include adequate band adjustment to control physical hunger, optimization of physical function and activity, and reinforcement of strategies to reduce energy intake.
