Abstract: Objective To investigate the status and influencing factors of bone mass abnormality in community-dwelling elderly people in Kaifeng City, and put forward scientific suggestions for the prevention and treatment of bone mass abnormality related diseases in this area. Methods Questionnaire survey, physical examination and bone mineral density measurement were conducted on healthy people aged over 60 years old in a community in Kaifeng City from January to May, 2019. Descriptive epidemiological method was used for analysis, and multivariate Logistic regression analysis was used to analyze the influencing factors of bone mass abnormality. Results A total of 700 healthy people aged 60 to 90 years old in Kaifeng City were analyzed, including 285 males （40.7%） and 415 females （59.3%）. One hundred and six cases of bone mass abnormality were detected in men （37.2%, 106/285）, and 309 cases in women （74.5%, 309/415） ,respectively. Multivariate Logistic regression analysis showed that men who took calcium tablets （OR=0.135）, moderate-intensity exercise （OR=0.185）, adequate sleep duration and average （OR=0.205, 0.121） had lower risk of bone mass abnormality; Women with hypertension （OR=1.754） had higher risk of bone mass abnormality, and women who took calcium tablets （OR=0.187）, adequate sleep duration and average （OR=0.458, 0.417） had lower risk of bone mass abnormality. Conclusion The incidence of bone mass abnormality is relatively high in people aged over 60 years old in community of Kaifeng City, especially elderly women. The influencing factors of bone mass abnormality in community elderly of different genders are not completely the same, and more attention should be paid when preventing and treating osteoporosis-related diseases.
