Abstract:To investigate influencing factors of sarcopenia in community-dwelling elderly of Huangshi in Hubei Province and to provide related evidence for the intervention measures. Methods The elderly people who had free check-ups at three community health centers of Huangshi in Hubei Province were selected, among which 77 with sarcopenia were enrolled into case group, and 156 non-sarcopenia elderly people were into control group.General information questionnaire, the Activities of Daily Living Scale (ADL), Mini Nutritional Assessment Scale(MNA), and the Pittsburgh Sleep Quality Index (PSQI) were used for all the subjects. Univariate factor analysis and multiple stepwise regression analysis were used for analysis of influencing factors. Results Univariate factor analysis showed that there were significant differences between the case group and the control group in low weight, monthly income, marital status, physical activity of daily living (PADL), instrumental activity of daily living (IADL), good nutrition and poor sleep quality ( p< 0.05). Multiple stepwise regression analysis showed that low weight, low monthly income, PADL disability and poor sleep quality were the risk factors for sarcopenia of the community-dwelling elderly in Huangshi while good nutrition was the protective factor for sarcopenia ( p< 0.05). Conclusions Sarcopenia in community-dwelling elderly of Huangshi is affected by many factors. Effective measures based on the risk factors should be taken to decline the risk of sarcopenia in the elderly.
