减肥可以减少与超重或肥胖相关的健康风险。然而，最有效的减肥方法仍不清楚。一些项目强调体育活动，另一些则强调饮食，但现有的证据对于这些单独或组合是否更有效是混合的。我们的目的是检查联合行为体重管理计划（BWMPs）的临床有效性相比，单一成分的计划，使用研究内比较。我们纳入了在超重和肥胖成年人（体重指数≥ 25）中进行的至少12个月随访的BWMPs联合治疗与仅饮食或仅体力活动方案相比的随机对照试验。对9个数据库进行了系统检索，两位审查员独立提取了数据。采用基线观察值结转法，对组合BWMP与仅饮食BWMP以及组合BWMP与仅体力活动BWMP在3 - 6个月和12 - 18个月时体重变化的平均差异进行随机效应荟萃分析。总共纳入了8项研究，代表1 022名参与者，其中大多数是妇女。6项研究符合合并BWMP vs仅饮食的入选标准。汇总结果显示，BWMP和仅饮食组之间的体重减轻相对于基线或3至6个月时无显著差异（-0.62 kg; 95% CI-1.67至0.44）。然而，在12个月时，在组合BWMP中检测到显著更大的体重减轻（-1.72 kg; 95% CI-2.80至-0.64）。5项研究符合合并BWMP与仅体力活动的入选标准。汇总结果显示，在3至6个月（-5.33 kg; 95% CI-7.61至-3.04）和12至18个月（-6.29 kg; 95% CI-7.33至-5.25）时，合并BWMP的体重减轻显著更大。在短期内，仅饮食和组合BWMP的体重减轻是相似的，但在长期内，当饮食和体力活动相结合时，体重减轻会增加。从短期和长期来看，单独基于体力活动的计划不如结合BWMP有效。
Weight loss can reduce the health risks associated with being overweight or obese. However, the most effective method of weight loss remains unclear. Some programs emphasize physical activity, others diet, but existing evidence is mixed as to whether these are more effective individually or in combination. We aimed to examine the clinical effectiveness of combined behavioral weight management programs (BWMPs) targeting weight loss in comparison to single component programs, using within study comparisons. We included randomized controlled trials of combined BWMPs compared with diet-only or physical activity-only programs with at least 12 months of follow-up, conducted in overweight and obese adults (body mass index ≥25). Systematic searches of nine databases were run and two reviewers extracted data independently. Random effects meta-analyses were conducted for mean difference in weight change at 3 to 6 months and 12 to 18 months using a baseline observation carried forward approach for combined BWMPs vs diet-only BWMPs and combined BWMPs vs physical activity-only BWMPs. In total, eight studies were included, representing 1,022 participants, the majority of whom were women. Six studies met the inclusion criteria for combined BWMP vs diet-only. Pooled results showed no significant difference in weight loss from baseline or at 3 to 6 months between the BWMPs and diet-only arms (–0.62 kg; 95% CI –1.67 to 0.44). However, at 12 months, a significantly greater weight-loss was detected in the combined BWMPs (–1.72 kg; 95% CI –2.80 to –0.64). Five studies met the inclusion criteria for combined BWMP vs physical activity-only. Pooled results showed significantly greater weight loss in the combined BWMPs at 3 to 6 months (–5.33 kg; 95% CI –7.61 to –3.04) and 12 to 18 months (–6.29 kg; 95% CI –7.33 to –5.25). Weight loss is similar in the short-term for diet-only and combined BWMPs but in the longer-term weight loss is increased when diet and physical activity are combined. Programs based on physical activity alone are less effective than combined BWMPs in both the short and long term.
