Older Hispanics routinely exhibit unhealthy beliefs about "normal" aging trajectories, particularly related to exercise and physical function. We evaluated the prospective effects of age reattribution on physical function in older Hispanics. Participants ( = 565, ≥60 years) were randomly assigned into (a) treatment group-attribution-retraining, or (b) control group-health education. Each group separately engaged in four weekly 1-hr group discussions and 1-hr exercise classes, followed by monthly maintenance sessions. The Short Physical Performance Battery (SPPB) measured physical function throughout the 24-month intervention. No significant difference in physical function between intervention arms was evident over time. However, both groups experienced significant improvements in physical function at 24 months (β = 0.43, 95% confidence interval [CI] = [0.16, 0.70]). Participating in the exercise intervention was associated with improvements in physical function, although no additional gains were apparent for age attribution-retraining. Future research should consider strengthening or modifying intervention content for age reattribution or dosage received.
老年人习惯性地表现出对“正常”衰老轨迹的不健康信念，尤其是与运动和身体功能相关的信念。我们评估了年龄再归因对老年西班牙裔人身体功能的前瞻性影响。参与者（n=565，年龄≥60 岁）被随机分配到（a）治疗组-归因再训练，或（b）对照组-健康教育。每个组分别进行了四次每周 1 小时的小组讨论和 1 小时的运动课程，然后是每月的维持课程。简短体能表现测试（SPPB）在整个 24 个月的干预过程中测量身体功能。随着时间的推移，干预组之间的身体功能没有明显差异。然而，两组在 24 个月时身体功能都有显著改善（β=0.43，95%置信区间[CI]：[0.16，0.70]）。参与运动干预与身体功能的改善有关，尽管年龄归因再训练没有明显的额外收益。未来的研究应该考虑加强或修改年龄归因或剂量的干预内容。
