There were limited studies specifically evaluating whether the difference of the prevalence of sarcopenia exists in men and women in older adults from rural areas in China. The aim of this study was to compare the prevalence of sarcopenia between men and women in a rural area in eastern China and to explore the underlying causes.
This study included 1,105 participants aged 60-89 years. Muscle mass was measured by bio-electrical impedance analysis. Hand grip strength was measured by Jamar Hydraulic Hand Dynamometer. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia-2019 Consensus. Data were analyzed using log-binomial and linear regression.
The prevalence of sarcopenia was 21.7% in women and 12.9% in men among the study cohort. After adjusting for age, education level, number of diseases, income level, smoking, drinking, and eating habits, proportion of people with sarcopenia was 1.49-fold greater in women than in men (PR = 1.49, 95% CI [1.01-2.26], = 0.055).
The prevalence of sarcopenia in elderly women in this rural area of eastern China is higher than in men, suggesting that women in rural areas in China seem to be more vulnerable for sarcopenia, thus early screening and prevention need to be provided for them to address such gender disparity in health.
在中国农村地区，针对老年人，有关男性和女性之间肌少症患病率差异的研究非常有限。本研究旨在比较中国东部农村地区男性和女性肌少症的患病率，并探讨其潜在原因。
本研究纳入了 1105 名 60-89 岁的参与者。肌肉量通过生物电阻抗分析进行测量。手握力使用 Jamar 液压握力计进行测量。根据亚洲肌少症工作组 2019 共识，诊断肌少症。使用对数二项式和线性回归分析数据。
在研究队列中，女性肌少症的患病率为 21.7%，男性为 12.9%。在校正年龄、教育水平、疾病数量、收入水平、吸烟、饮酒和饮食习惯后，女性患肌少症的比例比男性高 1.49 倍（PR=1.49，95%CI[1.01-2.26]，P=0.055）。
本研究中，中国东部农村地区老年女性肌少症的患病率高于男性，这表明中国农村地区的女性似乎更容易患肌少症，因此需要为她们提供早期筛查和预防措施，以解决健康方面的这种性别差异。
