OBJECTIVES: The European Working Group on Sarcopenia in Older People 2 (EWGSOP2) recently defined the new concept of probable sarcopenia to help improve screening and prevent future sarcopenia. We investigated the prevalence of probable sarcopenia, defined as weak grip strength, in community-dwelling older Colombian adults, and examined the long-term associated conditions. DESIGN: Cross-sectional study. SETTING: Urban and rural Colombian older adults from the "Estudio Nacional de Salud, Bienestar y Envejecimiento (SABE) study". PARTICIPANTS: 5237 Colombian older adults aged ≥60 years. MEASUREMENTS: Probable sarcopenia was assessed following the cut-off points for weak grip strength recommended by EWGSOP2 guidelines. Odds ratios (ORs) of the relationship between long-term conditions and probable sarcopenia were determined using logistic regression. RESULTS: The prevalence of probable sarcopenia defined as weak grip strength was 46.5% [95% confidence interval (CI), 45.1-47.8]. Physical inactivity "proxy" (OR 1.35, 95% CI 1.14-1.59); diabetes (OR 1.32, 95% CI 1.11-1.56); and arthritis, osteoarthritis, and rheumatism (OR 1.44, 95% CI 1.25-1.67) were independently associated with probable sarcopenia. CONCLUSIONS AND IMPLICATIONS: We found that almost half of all the Colombian older adults in our sample had probable sarcopenia. Individuals with physical inactivity, diabetes, arthritis, or osteoarthritis and rheumatism had a higher prevalence of probable sarcopenia. Probable sarcopenia is clinically highly relevant, and several of the factors associated with this condition are potentially preventable, treatable, and reversible.
目的：欧洲老年人肌肉减少症工作组 2 （EWGSOP2）最近定义了新的疑似肌肉减少症概念，以帮助改善筛查并预防未来的肌肉减少症。我们调查了社区居住的哥伦比亚老年人中，新定义的疑似肌肉减少症（握力弱）的流行情况，并研究了其与长期相关疾病的关系。
设计：横断面研究。
地点：来自“国家健康、福利和老龄化研究（SABE）”的城乡哥伦比亚老年人。
参与者：5237 名≥60 岁的哥伦比亚老年人。
测量：采用 EWGSOP2 指南推荐的握力弱切点评估疑似肌肉减少症。使用逻辑回归确定长期疾病与疑似肌肉减少症之间关系的比值比（OR）。
结果：根据 EWGSOP2 指南定义的握力弱，疑似肌肉减少症的患病率为 46.5%（95%可信区间 45.1-47.8）。身体活动不足“指标”（OR 1.35，95%可信区间 1.14-1.59）；糖尿病（OR 1.32，95%可信区间 1.11-1.56）；关节炎、骨关节炎和风湿病（OR 1.44，95%可信区间 1.25-1.67）与疑似肌肉减少症独立相关。
结论和意义：我们发现，我们样本中近一半的哥伦比亚老年人患有疑似肌肉减少症。身体活动不足、糖尿病、关节炎或骨关节炎和风湿病的个体，患有疑似肌肉减少症的比例更高。疑似肌肉减少症在临床上具有重要意义，并且与这种情况相关的几个因素是潜在可预防、可治疗和可逆转的。
