To explore the relationship of BMI and WC with muscle/adipose tissue mass ratios and with trunk adipose tissue distribution, based on an anatomical 5-compartment model, by dissection of cadavers of elderly persons.
Cross-sectional explorative study.
Brussels Cadaver Analysis Study.
Cadavers of twenty-nine white Caucasian elderly persons (17 females and 12 males, aged 78.1±6.9 years).
Whole body and trunk composition were determined at the anatomical tissue-system level by direct dissection.
BMI and WC were significantly and positively related to absolute tissue masses in both sexes. Muscle tissue mass, adipose tissue mass and trunk internal adipose tissue mass correlated better with BMI (r-values between 0.68 and 0.89) than with WC (r-values between 0.49 and 0.71). BMI was significantly and inversely related with various muscle/adipose tissue ratios in both sexes (r-values between -0.54 and -0.68). WC correlated with muscle/adipose tissue ratios in females only (r-values between -0.55 and -0.64). BMI was also significantly related to trunk adipose tissue distribution in elderly females, but not in males. When comparing individual tissue proportions within and between adjacent BMI-classifications or WC categories, body composition varied considerably.
Our results show that BMI and WC are significantly related with adipose tissue mass and with several ratios of muscle to adipose tissue in elderly subjects. However, cautious clinical interpretation is warranted since important differences in tissue mass proportions were found in subjects with similar BMI and/or WC values.
通过对老年人尸体进行解剖，基于解剖学 5 compartment 模型，探讨 BMI 和 WC 与肌肉/脂肪组织比以及躯干脂肪组织分布的关系。
横断面探索性研究。
布鲁塞尔尸体分析研究。
29 名白种老年人的尸体（17 名女性和 12 名男性，年龄 78.1±6.9 岁）。
通过直接解剖，在解剖组织系统水平上确定全身和躯干成分。
BMI 和 WC 与两性的绝对组织质量呈显著正相关。肌肉组织质量、脂肪组织质量和躯干内部脂肪组织质量与 BMI 的相关性更好（r 值在 0.68 和 0.89 之间），而与 WC 的相关性较差（r 值在 0.49 和 0.71 之间）。BMI 与两性的各种肌肉/脂肪组织比呈显著负相关（r 值在-0.54 和-0.68 之间）。WC 仅与女性的肌肉/脂肪组织比相关（r 值在-0.55 和-0.64 之间）。BMI 也与老年女性的躯干脂肪组织分布显著相关，但与男性无关。当比较 BMI 分类或 WC 类别内和之间的个体组织比例时，身体组成差异很大。
我们的结果表明，BMI 和 WC 与老年人的脂肪组织质量以及肌肉与脂肪组织的几个比值显著相关。然而，由于在具有相似 BMI 和/或 WC 值的受试者中发现了重要的组织质量比例差异，因此需要谨慎的临床解释。
