Abstract：Objective To comprehensively and multi-levelly explore the influencing factors of frailty among Chinese elderly based on health ecology model,providing a theoretical basis for developing interventions to improve frailty in the el-derly.Methods A total of 5 935 adults aged 65 and above from the 2017-2018 China Longitudinal Healthy Longevity Survey(CLHLS)were included.Using frailty status as the dependent variable and factors across the five levels of health ecology model as independent variables,logistic regression models were constructed to identify influencing factors of frail-ty.Results The explanatory power of the model increased with the inclusion of variables from more levels,with the most significant improvements observed after adding interpersonal network and psychosocial-behavioral factors.The regression results showed that at the psychological-behavioral level,drinking(OR=0.632,95%CI:0.484-0.825),smoking(OR=0.674,95%CI:0.519-0.876),physical exercise(OR=0.440,95%CI:0.361-0.535),vegetable consumption(OR=0.640,95%CI:0.504-0.813);in the social network layer of family community,rural residence(OR=0.814,95%CI:0.685-0.967),living alone(OR=0.370,95%CI:0.292-0.468),being married(OR=0.492,95%CI:0.402-0.603),occasionally socialize with friends(OR=0.297,95%CI:0.235-0.376),frequently socialize with friends(OR=0.196,95%CI:0.162-0.236);at the living and working environment level,primary education(OR=0.752,95%CI:0.616-0.916),sufficient income(OR=0.676,95%CI:0.527-0.867);at the economic policy environment level,and high an-nual precipitation of the economic policy environment layer(OR=0.805,95%CI:0.650-0.998)were protective factors against frailty in the elderly(all P<0.05).In the personal trait level,75-84 years old(OR=3.352,95%CI:2.345-4.791),≥85 years old(OR=13.045,95%CI:9.192-18.511);at the psychological-behavioral level,depression(OR=1.516,95%CI:1.281-1.795),anxiety(OR=1.500,95%CI:1.170-1.922),and high per capita GDP of the economic policy environment layer(OR=1.337,95%CI:1.132-1.579)were risk factors against frailty in the elderly(all P<0.05).Conclusions The health ecology model offers a comprehensive framework for analyzing frailty influencing factors.Psy-chosocial-behavioral factors and interpersonal networks should be prioritized when designing frailty management and inter-vention strategies for the elderly.
