To estimate the prevalence of dynapenia and examine potential risk factors for dynapenia using a sample of rural middle-aged and elderly Chinese. A cross-sectional study of 253 Chinese adults aged 50 years and older was conducted from June to August in 2022 in Nanjing. A questionnaire was used to collect data on all socioeconomic variables. Body weight, height, body fat percentage, grip strength, waist circumference, calf circumference, and gait speed were measured. The prevalence of dynapenia was 69.6 %, 62.3 % in men and 72.7 % in women respectively. Binary logistic regressions indicated significant associations between dynapenia and age (odds ratio [OR] = 2.59; 95 % confidence interval [CI] 1.63, 4.12; p < 0.001), educational level (OR = 0.55; 95 % CI 0.38, 0.80; p = 0.002). Dynapenia was prevalent among rural middle-aged and elderly people in southern China. Age and lower education level were both associated with dynapenia. Nutrition and physical activity should be strongly recommended as important strategies to maintain and improve muscle strength.
利用中国农村中老年人群样本，估计肌肉减少症的患病率，并探讨肌肉减少症的潜在危险因素。2022年6月至8月，在南京对253名年龄在50岁及以上的中国成年人进行了一项横断面研究。使用问卷收集所有社会经济变量的数据。测量体重、身高、体脂百分比、握力、腰围、小腿围和步速。肌肉减少症的患病率为69.6%，男性为62.3%，女性为72.7%。二元逻辑回归表明，肌肉减少症与年龄（比值比[OR]=2.59；95%置信区间[CI]1.63,4.12；p<0.001）、教育水平（OR=0.55；95%CI 0.38,0.80；p=0.002）之间存在显著关联。肌肉减少症在中国南方农村中老年人群中普遍存在。年龄和较低的教育水平都与肌肉减少症有关。应强烈推荐营养和体育活动作为维持和改善肌肉力量的重要策略。
