The primary objective of the study was to identify the effect of intervention strategies on attrition within a weight loss programme among adults aged 18 to 65 years. The secondary objective of the study was to assess the impact of such intervention strategies among female-only weight loss programmes. The literature search was performed in Ovid (CINAHL Plus, MEDLINE, EMBASE, Cochrane [Cochrane Database of Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Methodology Register], and PsycINFO). Studies must have identified weight loss as the main aim and compared the primary weight loss programme alone (control) with the primary weight loss programme coupled with an additional intervention strategy (intervention). Papers must have had a mean participant age between 18 and 65 years and available in English. Fifty-seven trials met the inclusion criteria and were included in the meta-analysis. Strategies that successfully reduced attrition included the incorporation of financial incentives (n = 8), a multicomponent approach (n = 13), and use of self-monitoring technology (n = 4). The majority of studies were of low to moderate methodological quality because of insufficient reporting. A limited number of female-only trials were found (n = 13). Implementation of financial incentives, multicomponent interventions, and self-monitoring technology help reduce attrition among adult weight loss programmes. Further studies are required to identify the impact of intervention strategies on attrition in women.
本研究的主要目的是确定干预策略对 18 至 65 岁成年人减肥计划中人员流失的影响。本研究的次要目的是评估此类干预策略对仅限女性的减肥计划的影响。文献检索在 Ovid（CINAHL Plus、MEDLINE、EMBASE、Cochrane [Cochrane 评价数据库、Cochrane 中心对照试验注册库和 Cochrane 方法学登记库]和 PsycINFO）中进行。研究必须将体重减轻确定为主要目标，并将主要减肥计划（对照）与主要减肥计划加额外干预策略（干预）进行比较。论文必须有 18 至 65 岁之间的平均参与者年龄，且必须为英文。57 项试验符合纳入标准并纳入荟萃分析。成功减少人员流失的策略包括纳入财务激励措施（n = 8）、多组分方法（n = 13）和使用自我监测技术（n = 4）。由于报告不充分，大多数研究的方法学质量为低至中度。发现的仅限女性的试验数量有限（n = 13）。实施财务激励措施、多组分干预措施和自我监测技术有助于减少成人减肥计划中的人员流失。需要进一步研究以确定干预策略对女性人员流失的影响。
