The aim of the present study was to examine the association between sarcopenia and nutritional status and physical activity among community-dwelling Chinese people aged 60 years and older.
This study was carried out on 836 community-dwelling Chinese individuals aged ≥60 years to evaluate sarcopenia using the Asian Working Group for Sarcopenia criteria. Sociodemographic characteristics and lifestyle habits were collected using a general questionnaire. Nutritional status was assessed using the Mini Nutritional Assessment and biochemical parameters, whereas physical activity was assessed using the long form of the International Physical Activity Questionnaire. In addition, univariate and multivariate analysis was used to analyze the association between sarcopenia with nutritional status and physical activity.
The total prevalence rate of sarcopenia was 10.5%, 47 (11.3%) men and 41 (9.7%) women who were classified as sarcopenia. The prevalence of sarcopenia was significantly lower among the participants of normal nutrition status. Compared with the participants with sarcopenia, those without sarcopenia had higher levels of prealbumin (P < 0.05) and hemoglobin (P < 0.05) for both sexes. In the multivariate model, after adjustment for all covariates, the Mini Nutritional Assessment score (adjusted OR 0.769, 95% CI 0.689-0.859, P < 0.05) was statistically significantly associated with sarcopenia, but the relationship between physical activity and sarcopenia was not significant.
The prevalence of sarcopenia in the Chinese community-dwelling population aged 60 years and older was high. There was a significant association between sarcopenia and nutritional status, but not with physical activity, based on a questionnaire. Further studies should evaluate whether maintaining a good nutritional status might be effective in lowering the risk of sarcopenia. Geriatr Gerontol Int 2017; 17: 1959-1966.
本研究旨在探讨社区居住的中国 60 岁及以上老年人中肌少症与营养状况和身体活动之间的关系。
本研究对 836 名社区居住的中国老年人进行了研究，使用亚洲肌少症工作组标准评估肌少症。使用一般问卷收集社会人口统计学特征和生活方式习惯。使用 Mini Nutritional Assessment 评估营养状况和生化参数，使用国际体力活动问卷长表评估身体活动。此外，还使用单因素和多因素分析来分析肌少症与营养状况和身体活动之间的关系。
肌少症的总患病率为 10.5%，47 名（11.3%）男性和 41 名（9.7%）女性被归类为肌少症。营养状况正常的参与者中肌少症的患病率明显较低。与肌少症患者相比，非肌少症患者的白蛋白（男女均 P<0.05）和血红蛋白（男女均 P<0.05）水平更高。在多因素模型中，调整所有协变量后，Mini Nutritional Assessment 评分（调整后的 OR 0.769，95%CI 0.689-0.859，P<0.05）与肌少症显著相关，但身体活动与肌少症之间的关系不显著。
中国社区居住的 60 岁及以上人群肌少症患病率较高。基于问卷调查，肌少症与营养状况显著相关，但与身体活动无关。进一步的研究应该评估保持良好的营养状态是否可以有效降低肌少症的风险。
