我们之前已经证明，行为干预组的种族构成不会影响实现的减肥效果。然而，目前尚不清楚干预者的竞争是否会影响干预结果。这项分析的目的是评估参与者和干预者之间的种族一致性对减肥维持试验(WLM)初始减肥阶段(阶段1)体重变化的影响。共有1,685名超重或肥胖(体重指数[BMI]25-45公斤/平方米)的成年人参加了WLM试验的第一阶段，他们正在服用治疗高血压和/或血脂异常的药物。所有参与者在一名训练有素的干预者的协助下，以15-20人为一组，接受为期6个月的强化行为干预。主要结局是6个月时体重的变化。参与者的平均年龄为55岁，其中67%为女性，44%为AA。17名干预者中有3人是再障，14人是非再障。73%的参与者与干预主义者的种族和谐一致。与种族不一致的参与者相比，与干预者属于同一种族的参与者的体重变化(−5.84 kg，SE 0.17)差异不大(−5.04 kg，SE 0.33)，相差0.8 kg，(p=0.04)。和谐性对体重变化的影响因种族而异(即种族与和谐性的交互作用显著，p=0.02)。在一项基于群体的行为干预的事后分析中，非AA参与者的种族一致性与略高的体重减轻相关。对于AA参与者来说，种族一致性与体重减轻无关。
We have previously shown that racial composition of behavioral intervention groups does not affect achieved weight loss. However, it is unclear if the race of the interventionist affects intervention outcomes. The objective of this analysis is to estimate the impact of race concordance between participant and interventionist on weight change in the initial weight loss phase (phase 1) of the Weight Loss Maintenance trial (WLM). A total of 1,685 overweight or obese adults (body mass index [BMI] 25–45 kg/m2) who were taking medication for hypertension and/or dyslipidemia participated in Phase I of the WLM trial. All participants received a 6-month intensive behavioral intervention in groups of 15–20 facilitated by a trained interventionist. The main outcome is change in weight at 6 months. Participants were on average 55 years of age, 67% female and 44% AA. Three of seventeen interventionists were AA, 14 were non-AA. Seventy-three percent of participants shared race concordance with the interventionist. There was a small but statistically significant difference in weight change of participants who were the same race as the interventionist (−5.84 kg, SE 0.17) compared to those who were not race concordant (−5.04 kg, SE 0.33), a difference of 0.8kg, (p= 0.04). The impact of concordance on weight change differed by race (i.e., interaction of race and concordance was significant, p= 0.02). In a post-hoc analysis of a group-based behavioral intervention, race concordance for Non-AA participants was associated with slightly greater weight loss. Race concordance was not associated with weight loss for AA participants.
