Background: Although socioeconomic support is recommended for frailtymanagement, its association with the prognosis of frailty is unclear.Methods: Using data from participants aged ≥65 years in the ChineseLongitudinal Healthy Longevity Survey (2008–2018), the associations betweensocioeconomic support (source of income, medical insurance, communitysupport, living status), onset of prefrailty/frailty, and worsening of prefrailty,were analyzed using multinominal logistic regression models. The associationsbetween self-reported low quality of life (QoL) and reversion of prefrailty/frailty were analyzed using multivariate logistic regression models. Associationswith mortality risk were analyzed using Cox proportional hazardregression models.Results: A total of 13,859 participants (mean age: 85.8 ± 11.1 years) containing2056 centenarians were included. Financial dependence was a risk factor for lowQoL among prefrail/frail individuals, but not among robust individuals. Havingcommercial or other insurance, and receiving social support from the communitywere protective factors for low QoL among prefrail/frail individuals and for theworsening of prefrailty. Continuing to work was a risk factor for low QoL, but aprotective factor for worsening of prefrailty. A negative association betweencontinuing to work and mortality existed in prefrail individuals aged <85 yearsand ≥85 years. Living alone was a risk factor for low QoL, but was notsignificantly associated with frailty prognosis.Conclusions: Prefrail and frail individuals were vulnerable to changes insocioeconomic support and more sensitive to it compared with robustindividuals. Preferential policies regarding financial support, social support,and medical insurance should be developed for individuals with frailty.
