摘要
背景:成功的老龄化包括在晚年保持身体活力、情感健康和有意义的社会关系。身体圆度指数(BRI)是一种身体形状的数字指标,作为评估成功衰老的潜在标志,正引起越来越多的兴趣。根据中国健康与退休纵向研究(CHARLS)的数据,本研究调查了BRI轨迹模式与中国老年人口成功老龄化的关系。方法:从CHARLS队列中抽取2517名60岁及以上的个体进行分析。在2011年、2013年和2015年测量了BRI,并通过基于群体的轨迹模型(GBTM)确定了其纵向模式。在2018年的随访中评估了成功的老龄化。为了研究BRI轨迹与成功衰老之间的联系,我们采用了二元逻辑回归,并辅以亚组分析和相互作用分析来检验效应修正。研究结果:确定了三种不同的BRI轨迹:低稳定(46.9 %),中稳定(43.0 %)和高上升(10.1 %)。中等稳定组与高稳定组相比,成功衰老的几率最大,其次是低稳定组,可能性略低。在控制一系列协变量后,中稳定组和低稳定组的个体成功衰老的几率显著更高,or分别为2.63(95 % CI: 1.45-5.12, P = 0.002)和2.52(95 % CI: 1.26-5.31, P = 0.012)。在敏感性分析中,中间稳定轨迹显示出与成功衰老最强烈和最一致的关联。结论:这项研究强调了监测老年人身体变化的必要性,并制定有针对性的健康策略,以支持成功的老龄化。
Association between body roundness index trajectories and successful aging among older adults in China: A nationally representative longitudinal cohort study.
Background: Successful aging involves maintaining physical vitality, emotional health, and meaningful social connections throughout late life. Body Roundness Index (BRI), a numerical indicator of body shape, is drawing growing interest as a potential marker for evaluating successful aging. Drawing on data from the China Health and Retirement Longitudinal Study (CHARLS), this research examined how BRI trajectory patterns were associated with successful aging in the older Chinese population.
Methods: The analysis included 2517 individuals aged 60 and above, drawn from the CHARLS cohort. BRI was measured in 2011, 2013, and 2015, and its longitudinal patterns were determined through group-based trajectory modeling (GBTM). Successful aging was assessed at the 2018 follow-up. To investigate the link between BRI trajectories and successful aging, we employed binary logistic regression, supplemented by subgroup and interaction analyses to test for effect modification.
Findings: Three distinct BRI trajectories were identified: low-stable (46.9 %), intermediate-stable (43.0 %), and high-rising (10.1 %). The intermediate-stable group had the greatest odds of successful aging compared to the high-rising group, followed by the low-stable group with a moderately lower likelihood. Upon controlling for a range of covariates, individuals in the intermediate-stable group and the low-stable group had significantly greater odds of successful aging, with ORs of 2.63 (95 % CI: 1.45-5.12, P = 0.002) and 2.52 (95 % CI: 1.26-5.31, P = 0.012), respectively. Across sensitivity analyses, the intermediate-stable trajectory showed the strongest and most consistent association with successful aging.
Conclusion: This study highlights the need to monitor body changes in older adults and develop targeted health strategies to support successful aging.
