: To examine the prevalence of sarcopenia and its association with protein intake in men and women in a multi-ethnic population. We used cross-sectional data from the HELIUS (Healthy Life in an Urban Setting) study, which includes nearly 25,000 participants (aged 18-70 years) of Dutch, South-Asian Surinamese, African Surinamese, Turkish, Moroccan, and Ghanaian ethnic origin. For the current study, we included 5161 individuals aged 55 years and older. Sarcopenia was defined according to the EWGSOP2. In a subsample ( = 1371), protein intake was measured using ethnic-specific Food Frequency Questionnaires. Descriptive analyses were performed to study sarcopenia prevalence across ethnic groups in men and women, and logistic regression analyses were used to study associations between protein intake and sarcopenia. Sarcopenia prevalence was found to be sex- and ethnic-specific, varying from 29.8% in Turkish to 61.3% in South-Asian Surinamese men and ranging from 2.4% in Turkish up to 30.5% in South-Asian Surinamese women. Higher protein intake was associated with a 4% lower odds of sarcopenia in the subsample (OR = 0.96, 95%-CI: 0.92-0.99) and across ethnic groups, being only significant in the South-Asian Surinamese group. Ethnic differences in the prevalence of sarcopenia and its association with protein intake suggest the need to target specific ethnic groups for prevention or treatment of sarcopenia.
: 研究目的在于，在多民族人群中，检测男性和女性的肌肉减少症流行情况及其与蛋白质摄入量的关系。我们使用了 HELIUS（城市生活中的健康）研究的横断面数据，该研究包含了近 25000 名参与者（年龄在 18-70 岁之间），分别来自荷兰、南亚苏里南、非洲苏里南、土耳其、摩洛哥和加纳族群。在本研究中，我们纳入了 5161 名 55 岁及以上的个体。肌肉减少症的定义依据 EWGSOP2 标准。在一个亚组（n=1371）中，使用特定族群的食物频率问卷来测量蛋白质摄入量。我们进行了描述性分析，以研究男性和女性中不同族群的肌肉减少症流行情况，同时使用逻辑回归分析来研究蛋白质摄入量与肌肉减少症之间的关联。我们发现，肌肉减少症的流行情况存在性别和族群特异性，在男性中，从土耳其族群的 29.8%到南亚苏里南族群的 61.3%不等，而在女性中，从土耳其族群的 2.4%到南亚苏里南族群的 30.5%不等。在亚组中，较高的蛋白质摄入量与肌肉减少症的发生几率降低 4%相关（OR=0.96，95%CI：0.92-0.99），并且在所有族群中都具有相关性，仅在南亚苏里南族群中具有统计学意义。肌肉减少症的流行情况及其与蛋白质摄入量的关联在不同族群中存在差异，这表明需要针对特定族群进行肌肉减少症的预防或治疗。
