某市老年肌肉衰减征影响因素分析

了解湖北省黄石市老年肌肉衰减征的影响因素,为采取相应的干预措施提供依据。方法2015 年6 月至2016 年6 月以湖北省黄石市3 个社区卫生服务站进行免费体检的老年人为研究对象进行肌肉衰减征的筛查,得到老年肌肉衰减征者77 例,再随机抽取同期进行体检的非肌肉衰减征老年人156 例作为对照组。用一般情况量表、活动能力量表、微型营养评定量表、匹兹堡睡眠质量量表对调查对象进行问卷调查,再用单因素分析和多因素进行老年人肌肉衰减征影响因素的分析。结果单因素分析显示肌肉衰减征组与对照组在体重过低、婚姻状况、月收入、躯体生活自理能力、工具性日常生活活动能力、营养良好、睡眠质量不佳上的差异有统计学意义（ p<0.05）;多因素分析显示体重过低、月收入较低、躯体生活自理能力功能障碍、睡眠质量不佳是黄石市老年人患肌肉衰减征的危险因素,营养良好是其保护因素（p <0.05）。结论黄石市老年人患肌肉衰减征受多种因素影响,应针对危险因素采取有效措施来降低老年人患肌肉衰减征的风险。

Influencing factors of sarcopenia in community-dwelling elderly of Huangshi

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.
