Sarcopenia has become a critical health concern in the global older population. However, limited studies have investigated the epidemiological characteristics and potential risk factors of sarcopenia in older individuals residing in rural coastal areas of China. This cross-sectional study involving sarcopenia screening was conducted in Ningbo City, including body composition measurements, and questionnaire surveys. Sarcopenia was diagnosed using the criteria outlined in the Asian Working Group for Sarcopenia 2019 Consensus. A total of 902 older adults aged ≥ 60 years (average age: 69.76 years) were included using a two-stage random sampling method from three villages in Ningbo. The prevalence of sarcopenia was 11.53%, with men (16.36%) exhibiting higher rates than women (7.93%). Multivariate logistic regression analysis identified age (odds ratio [OR]: 6.708, 95% confidence interval [CI]: 2.520-17.855), stroke (OR: 9.232, 95% CI: 1.917-44.447), and waist circumference (OR: 1.095, 95% CI: 1.030-1.165) as factors positively correlated with the occurrence of sarcopenia. Conversely, body mass index (OR: 0.347, 95% CI: 0.270-0.445) was negatively correlated with sarcopenia development. These findings underscore the need for specific health education, the collaborative prevention of comorbidities, and active screening for sarcopenia in the older population to reduce its disease burden.
肌肉减少症已成为全球老年人群中一个关键的健康问题。然而，针对中国沿海农村地区老年人肌肉减少症的流行病学特征和潜在危险因素的研究较少。本横断面研究在宁波市开展，涉及肌肉减少症筛查，包括身体成分测量和问卷调查。采用2019年亚洲肌肉减少症工作组共识中概述的标准诊断肌肉减少症。采用两阶段随机抽样方法，从宁波市三个村庄纳入了902名年龄≥60岁的老年人（平均年龄：69.76岁）。肌肉减少症的患病率为11.53%，男性（16.36%）的患病率高于女性（7.93%）。多因素逻辑回归分析确定年龄（比值比[OR]：6.708，95%置信区间[CI]：2.520 - 17.855）、中风（OR：9.232，95% CI：1.917 - 44.447）和腰围（OR：1.095，95% CI：1.030 - 1.165）是与肌肉减少症发生呈正相关的因素。相反，体重指数（OR：0.347，95% CI：0.270 - 0.445）与肌肉减少症的发展呈负相关。这些发现强调了开展针对性健康教育、协同预防合并症以及对老年人群积极筛查肌肉减少症以减轻其疾病负担的必要性。
