By definition, obesity corresponds to the presence of a mass of fatty tissue that is excessive with respect to the body mass. Body fat can be calculated in terms of age and sex by measuring the skinfold thickness in several different places. During the MONICA project, the survey of cardiovascular risk factor prevalence enabled us to measure the thickness of four skinfolds (biceps, triceps, subscapular, suprailiac) in 263 inhabitants of Lausanne (125 men, 138 women). In men aged 25-34, 21 +/- 5% of the body mass was composed of fat, in women 29 +/- 4%. The proportion of fat increases to 31 +/- 7% in men and 41 +/- 6% in women aged 55-64. A robust regression allows body fat to be simply expressed in terms of the body mass index. This allows us to confirm the validity of this index for evaluating the degree of obesity during an epidemiological study.
根据定义，肥胖是指相对于体重而言存在过量的脂肪组织。通过测量身体几个不同部位的皮褶厚度，可以根据年龄和性别计算体脂。在莫尼卡项目期间，对心血管危险因素患病率的调查使我们能够测量洛桑263名居民（125名男性，138名女性）的四处皮褶（肱二头肌、肱三头肌、肩胛下、髂嵴上）厚度。在25 - 34岁的男性中，21±5%的体重由脂肪组成，女性为29±4%。在55 - 64岁的男性中，脂肪比例增加到31±7%，女性为41±6%。稳健回归使体脂能够简单地根据体重指数来表示。这使我们能够在流行病学研究中确认该指数用于评估肥胖程度的有效性。
