心理韧性与中国老年人全因死亡率关联强度的异质性:一项前瞻性队列研究OA

Objective:To explore potential heterogeneity in the association between psychological resilience and all-cause mortality across four obesity indices and to identify subpopulations warranting particular attention.Methods:This cohort study included 7 481 eligible participants from the Chinese Longitudinal Healthy Longevity Survey(CLHLS)surveyed between 2011 and 2012.Cox proportional hazards model was employed to assess the associations between psychological resilience and all-cause mortality.Subpopulation treatment effect pattern plot(STEPP)analysis was further applied to investigate heterogeneity in this association strength among Chinese older adults.Results:Higher psychological resilience was significantly associated with a lower risk of all-cause mortality among Chinese older adults(all P＜0.001).Significant heterogeneity in the association strength was observed across subpopulations defined by a body shape index(ABSI)(P＜0.001),body roundness index(BRI)(P＜0.001),waist-to-height ratio(WHtR)(P＜0.001),and body mass index(BMI)(P＜0.001).Conclusion:The association strength between psychological resilience and all-cause mortality varies significantly among different subpopulations of Chinese older adults.Older adults classified as overweight by multiple indices are encouraged to maintain higher levels of psychological resilience to reduce all-cause mortality risk.
