What is the impact of the European Consensus on the diagnosis and prevalence of sarcopenia among institutionalized elderly persons?

Abstract Objective: To verify the impact of the European Consensus on the diagnosis and prevalence of sarcopenia among institutionalized elderly persons in Natal, Rio Grande do Norte, Brazil. Method: 219 elderly persons (≥60 years) of both genders were recruited for the study. Two criteria were initially used to calculate the prevalence of sarcopenia: criterion A, based on the European Consensus, considering only elderly persons with good physical and cognitive conditions and criterion B, considering all elderly individuals, regardless of their physical and/or cognitive condition. The association between sarcopenia and gender, age and body mass index (BMI) in the two groups was investigated using the chi-square test and the Student's t-test, with a significance level of 5%. Result: the diagnosis of sarcopenia according to Criterion A revealed a prevalence of 32% (95% CI: 22.54-43.21), whereas Criterion B identified a prevalence of 63.2% (95% CI: 56; 45-69,13). Despite the difference in the prevalence of sarcopenia using the two criteria employed (p【研究目的】验证欧洲肌肉减少症诊断共识对巴西北里奥格兰德州纳塔尔市机构养老老年人群肌肉减少症（sarcopenia）的诊断效果及患病率的影响。【研究方法】本研究共招募219名年龄≥60岁的男女老年受试者。初始采用两套标准计算肌肉减少症患病率：标准A基于欧洲共识，仅纳入身体及认知状况良好的老年人群；标准B则纳入所有老年个体，不考虑其身体和/或认知状况。采用卡方检验与学生t检验开展相关性分析，设定显著性水平为5%，以探究两组人群中肌肉减少症与性别、年龄及体质量指数（BMI）的关联。【研究结果】依据标准A诊断的肌肉减少症患病率为32%（95%置信区间：22.54~43.21），而标准B检出的患病率为63.2%（95%置信区间：56.45~69.13）。尽管采用两套所用诊断标准得到的肌肉减少症患病率存在差异（p
