我们研究了种族/民族对给定体重指数（BMI）的育龄妇女体脂分布的影响。用数字秤、壁挂式体重计和双能x线吸收仪分别测量了708名16至33岁的健康黑人、白人和西班牙裔女性的体重、身高和体脂分布。在调整BMI、初潮年龄、人口统计学和生活方式变量后，采用多元线性回归对种族/民族与不同体脂分布变量之间的关系进行建模。对于给定的BMI，白人女性的总脂肪量（FM（总））、躯干脂肪量（FM（躯干））和腿部脂肪量（FM（腿部））最高，而西班牙裔女性的FM（躯干）百分比（%FM（躯干））和躯干与肢体脂肪质量比（FMR（躯干与肢体））最高。相反，黑人女性的FM（总）、FM（躯干）、体脂量百分比（%FM）、%FM（躯干）和FMR（躯干与肢体）最低，FM（腿部）百分比最高。这一比例在白人和西班牙裔人中相似，而在黑人中较低。种族与BMI的相互作用对于几乎所有体脂分布变量都是显著的。黑人和白人在FM（躯干）、%FM（躯干）、FMR（躯干到四肢）、%FM（腿）和%FM上的差异随着BMI的增加而增加，黑人和西班牙裔在FM（躯干）、%FM（躯干）、FMR（躯干到四肢）和FM（腿）上的差异随着BMI的增加而增加。总而言之，在给定的身体质量指数下，育龄妇女的体脂分布因种族而异。这些发现提出了关于普遍应用基于bmi的肥胖指南的问题，并对患者进行心血管疾病和代谢并发症的个体危险因素教育。(C) 2009爱思唯尔公司版权所有。
We examined the influence of race/ethnicity on body fat distribution for a given body mass index (BMI) among reproductive-aged women. Body weight, height, and body fat distribution were measured with a digital scale, wall-mounted stadiometer, and dual-energy x-ray absorptiometry, respectively, on 708 healthy black, white, and Hispanic women 16 to 33 years of age. Multiple linear regression was used to model the relationship between race/ethnicity and different body fat distribution variables after adjusting for BMI, age at menarche, and demographic and lifestyle variables. For a given BMI, white women had the highest total fat mass (FM(total)), trunk fat mass (FM(trunk)), and leg fat mass (FM(leg)), whereas Hispanic women had the highest percentage of FM(trunk) (%FM(trunk)) and trunk-to-limb fat mass ratio (FMR(trunk-to-limb))- Conversely, black women had the lowest FM(total), FM(trunk), percentage body fat mass (%FM), %FM(trunk), and FMR(trunk-to-limb), and the highest percentage of FM(leg). The %FM was similar in whites and Hispanics and lower in blacks. The race x BMI interactions were significant for almost all of the body fat distribution variables. Increasing in differences with increasing BMI were apparent between blacks and whites in FM(trunk) %FM(trunk), FMR(trunk-to-limb), %FM(leg) and %FM, and between blacks and Hispanics in FM(trunk), %FM(trunk), FMR(trunk-to-limb) and FM(leg). In summary, the distribution of body fat for a given BMI differs by race among reproductive-aged women. These findings raise questions regarding universally applied BMI-based guidelines for obesity and have implications for patient education regarding individual risk factors for cardiovascular disease and metabolic complications.
