Mesure des plis cutanés et masse adipeuse corporelle: une précision de l'excès de poids dans l'enquête épidémiologique
Sozial- Und Präventivmedizin
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.
