我国≥60岁老年人共病与跌倒的关联性研究OA北大核心CSTPCD

Objective To investigate the relationship between comorbidities and the risk of fall among community-dwelling older adults aged 60 years and above in 3 provinces vinces of China.Methods Using multi-stage stratified whole cluster random sampling method,16 199 community-dwelling elderly people aged 60 years and above were selected for questionnaire survey and physical measurements in 3 provinces of China in 2019,and 16 172 people were finally included for analysis.Study participants were categorized into co-morbid and non-co-morbid groups based on whether they suffered from ≥2 diseases.The propensity score matching(PSM)method was used to successfully match 6 153 pairs of co-morbid and non-co-morbid groups in a ratio of 1∶1 according to the underlying conditions,and the relationship between co-morbidities and the risk of falls was analyzed by using binary conditional and unordered multiclassified Logistic regression.Results In the surveyed,elderly population 15.02 per cent of the elderly had fallen in the past 1 year and 67.97 per cent were at risk of falling,and the differences between the occurrence and risk of fall history were statistically significant by age,sex,urban/rural area,marital status,education level,and incapacitated condition(P＜0.001).The covariates of the two groups were balanced after the PSM adjustment,and the logistic regression The results showed that the probability of fall event in the past year increased by 71％in the co-morbid group compared to the non-co-morbid group(OR=1.71,95％CI:1.54-1.89).There was also a 24％increase falls risk in the co-morbid group compared to the non-co-morbid group(OR=1.24,95％CI:1.15-1.34).Conclusions Co-morbidities increase the risk of falls for elder people,and the government should pay attention for this issue and strengthen the prevention and management of chronic co-morbidities and falls in the elderly.
