This study describes sex differences in obesity and body fat distribution using commonly used assessment methods in 140 men and 245 women age 65-96 years from Rancho Bernardo, California. Significant correlations were shown among all obesity measures. The waist/hip ratio was more strongly correlated with the truncal fat/leg fat ratio in women than in men. The waist/hip ratio correlated significantly with the subscapular/ triceps skinfold ration in women only. In both sexes, waist circumference was more strongly correlated with body mass index and the percentage of body fat by bioelectric impedance analysis and dual-energy X-ray absorptiometry than with the waist/hip ratio. In those aged over 80 years, age stratification showed that the waist/hip ration was not correlated with any other measurement of obesity or fat distribution in men and correlated only with subscapular skinfolds in women. Waist circumference, however, correlated significantly with almost all other measures of central obesity in older and younger men and women. Estimates of upper body (central) fat distribution appear to be age specific. After age 80, the waist/hip ratio is a poor method of assessing central or visceral adiposity, and waist circumference is a better measure of body fat distribution.
本研究采用常用评估方法，对来自加利福尼亚州兰乔贝纳多的140名65至96岁男性和245名65至96岁女性的肥胖及体脂分布的性别差异进行了描述。所有肥胖指标之间均显示出显著相关性。与男性相比，女性的腰臀比与躯干脂肪/腿部脂肪比的相关性更强。仅在女性中，腰臀比与肩胛下/肱三头肌皮褶比显著相关。在男女两性中，通过生物电阻抗分析和双能X线吸收法测得的腰围与体重指数及体脂百分比的相关性，比与腰臀比的相关性更强。在80岁以上人群中，年龄分层显示，腰臀比与男性的任何其他肥胖或脂肪分布测量指标均无相关性，而在女性中仅与肩胛下皮褶相关。然而，腰围与老年和年轻男性及女性的几乎所有其他中心性肥胖测量指标均显著相关。上身（中心性）脂肪分布的估计似乎具有年龄特异性。80岁以后，腰臀比是评估中心性或内脏脂肪肥胖的较差方法，而腰围是衡量体脂分布的更好指标。
