Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g=-0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.
体重偏见存在于许多重要的生活领域，因此需要采取干预措施来减少对体重有偏见的态度和观念。尽管体重偏见干预措施的有效性受到了质疑，但据我们所知，尚未对这些干预措施进行荟萃分析。这项荟萃分析评估了体重偏见干预措施对体重偏见态度和观念的影响，并探讨了潜在的调节因素。如果干预措施使用的是成人样本且采用了经过验证的体重偏见态度测量方法，则这些干预措施符合要求，这导致纳入了29篇文章中所代表的30项研究。使用逆权重的随机效应方法得出，态度和观念的平均效应大小估计值为g = -0.33（分数越低表明体重偏见越小）。干预类型、出版物类型和人群类型不是显著的调节因素，但显示出值得注意的趋势。结果揭示了体重偏见干预措施对体重偏见态度和观念有微小的积极影响，并为未来的干预措施提供了有用的信息。
