Abstract

Objective: Standard behavioral weight loss (SBT) is a first-line intervention for obesity, but its efficacy with Black adults is limited. Some preliminary work suggests that acceptance-based behavioral therapy (ABT), which integrates mindful decision making, experiential acceptance, and reflection on values, may be a better fit for the needs of Black adults. In this fully powered secondary data analysis, we compared the efficacy of SBT and ABT for Black adults.

Method: Black and non-Hispanic White adults (N = 737) with overweight or obesity (body mass index = 27-50 kg/m²) were enrolled in one of the five randomized controlled trials investigating the effectiveness of ABT versus SBT. Analyses assessed the impact of race, treatment condition, and their interaction on percent weight loss at posttreatment and first follow-up assessment while controlling for clinical trial.

Results: The interaction effects between race and treatment condition on weight loss were trending toward significance (p < .05) at posttreatment, F(1, 729) = 2.74, p = .089, but not at follow-up, F(1, 729) = .003, p = .957. Pairwise comparisons revealed that the disparity in posttreatment weight loss between Black and White participants in the SBT condition (M = 3.5%, p = .001) was attenuated in the ABT condition (M = 1.5%, p = .05).

Conclusions: ABT has promise for supporting Black adults in weight loss attempts, although weight regain after treatment remains persistent for Black and White adults alike. Future research is warranted to continue developing this treatment approach as a tool to reduce health disparities. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

传统与接受性行为减肥效果的种族差异。

目的：标准行为减肥（SBT）是治疗肥胖的一线干预措施，但其对黑人成年人的疗效有限。一些初步的研究表明，基于接受的行为疗法（ABT）可能更适合黑人成年人的需求，它将正念决策、经验接受和价值观反思结合在一起。在这项充分支持的二次数据分析中，我们比较了SBT和ABT对黑人成年人的疗效。方法：黑人和非西班牙裔白人成年人（N = 737）超重或肥胖（体重指数= 27-50 kg/m²）被纳入5项随机对照试验之一，研究ABT与SBT的有效性。在控制临床试验的情况下，分析评估了种族、治疗条件及其相互作用对治疗后和第一次随访评估时体重减轻百分比的影响。结果：种族与治疗条件对体重减轻的交互作用在治疗后有显著性趋势（p < 0.05）， F(1729) = 2.74, p = 0.089，但在随访时无显著性趋势，F(1729) = 0.003, p = 0.957。两两比较显示，黑人和白人受试者在SBT组（M = 3.5%, p = .001）治疗后体重减轻的差异在ABT组（M = 1.5%, p = .05）中减弱。结论：ABT有希望支持黑人成年人减肥，尽管黑人和白人成年人在治疗后体重反弹仍然持续存在。未来的研究有必要继续发展这种治疗方法，作为减少健康差距的工具。（PsycInfo Database Record (c) 2025 APA，版权所有）。
