背景：墨西哥老年人与其他种族群体的身体成分（特别是骨骼肌质量）的比较此前尚未有报道。我们测试了这样的假设：墨西哥西北部 (Mex) 的老年人与纽约居住的白种人 (Cauc) 和非裔美国人 (AA) 相比，具有相似的总附肢骨骼肌 (TASM)。方法：对年龄 60-98 岁的 289 名墨西哥人（135 名男性和 154 名女性）、166 名 AA（36 名男性和 130 名女性）和 229 名 Cauc（64 名男性和 165 名女性）进行了评估。通过全身双能 X 射线吸收测定法测量总和局部脂肪和瘦肉组织，其中 TASM 是手臂和腿的无骨和无脂肪瘦组织的总和。通过 ANCOVA 测试 TASM 的差异，以年龄、身高和体重指数 (BMI) 作为协变量。结果：根据种族、年龄、身高和 BMI 调整后的 TASM，男性和女性分别为 22.6 +/- 0.2 kg 和 17.8 +/- 0.1 kg（p
Background: How body composition, specifically skeletal muscle mass, compares in Mexican elderly to other ethnic groups has not previously been reported. We tested the hypothesis that older adults from Northwest Mexico (Mex) would have similar total appendicular skeletal muscle (TASM) compared with New York dwelling Caucasians (Cauc) and African-Americans (AA). Methods: Two hundred and eighty nine Mex (135 males and 154 females), 166 AA (36 males and 130 females) and 229 Cauc (64 males and 165 females), aged 60-98 years were assessed. Total and regional fat and lean tissues were measured by whole-body dual energy X-ray absorptiometry where TASM is the sum of arm and leg bone-free and fat-free lean tissue. Differences in TASM were tested by ANCOVA, with age, height, and body mass index (BMI) as covariates. Results: TASM adjusted for ethnicity, age, height and BMI, were 22.6 +/- 0.2 kg and 17.8 +/- 0.1 kg for males and females, respectively (p
