Abstract:
Objective:To analyze the risk factors of falls among community-dwelling elderly people and provide references for the formulation of targeted fall prevention measures.Methods:This study was a cross-sectional survey. The multi-stage stratified random sampling method was used to conduct a questionnaire survey on the health and care needs of 5 997 community-dwelling elderly people in Beijing from February to August 2017. Logistic regression and association rules were used to analyze the risk factors of elderly people falling easily in community.Results:A total of 1 935 elderly people (32.27%, 1 935/5 997) experienced falls within 3 years. Logistic regression analysis showed that female, age ≥75 years, poor marital status (unmarried/widowed/divorced) , overweight or obesity, living in a bungalow, conscious general or unhealthy health, chronic diseases (diabetes/coronary heart disease/stroke/osteoarthropathy/Parkinson's disease, etc.) , medication taken ≥5 types, poor eyesight, poor hearing were risk factors for falls in the community-dwelling elderly people ( P<0.05) . The correlation between risk factors was explored by association rules, and it was found that the elderly with low socioeconomic level and decreased perceived health level, obesity accompanied by sensory disorders and multiple drug use, cardiovascular and cerebrovascular diseases and movement disorders had an increased risk of falling. Conclusions:Community nursing staffs should focus on screening the fall risk of elderly people in communities with low socioeconomic status, perceived poor health, obesity, sensory and perceptual disorders, co-existing diseases and multi-drug use, and reduce the fall risk of elderly people in communities through targeted measures such as modifying the living environment suitable for aging, wearing visual and hearing correction equipment, controlling of obesity, chronic disease management and simplification of drug prescriptions.
