Study on the variation trend and risk factors of fragility in rural middle-aged and aged people in China

Objective To explore the variation trend and risk factors of caused fragility in rural middle-aged and aged people in China.Methods Based on the investigation data of China's Health for the Elderly,6137 rural respondents from four surveys in 2011,2013,2015 and 2018 were enrolled in this analysis.Latent growth mixture model was used to distinguish the variation trend of fragility.Fixed effects model and mixed logistic regression model were used to analyze the influencing factors of rural residents'fragility and high fragility risk.Results The growth trend of rural residents'fragility index could be divided into medium-risk rising group(37.6%),high risk group(21.1%)and low-risk rising group(41.4%).Age(β=0.009),smoking cessation(β=0.004),unemployed(β=0.017),unmarried/divorced or widowed(β=0.019),household per capita consumption(β=0.000)were positively correlated with fragility index,while living near children(β=-0.004)and social interaction(β=-0.003)were negatively correlated with fragility.Older adults(OR=1.10),unmarried/divorced or widowed(OR=1.49),and women(OR=4.03)were more likely to have a high fragility risk;Living near children(OR=0.89),weekly contact with children(OR=0.87),currently working(OR=0.50),and social interaction(OR=0.74)could significantly reduce the risk of high fragility.Conclusions The fragility risk of rural residents increases along with age,and the fragility risk is affected by socio-economic status.Intergenerational support and social interaction are the effective ways to reduce the fragility risk of rural residents.
