【 摘 要 】

The objective ofthe present study is to define adiposity patterns in women. The study was conductedat a municipal health care center in Belo Horizonte, Minas Gerais, with 827women aged 12-65 years. All participants performed several anthropometric measurementsand answered a questionnaire with socio-economic, demographic, obstetric andlife style variables. Factorial analysis was used as a multivariate techniqueto identify clustering and independence of anthropometric variables. Factoranalysis identified three factors that explain 85.97% of the total variance.The first component was represented by skinfolds, the second by the Body MassIndex (BMI) and arm circumference (AC), and the third by the waist to hip ratio(WHR). These factors explained 38.42%, 29.03% and 18.52% of the variance, respectively.Positive associations were observed among all variables. Cluster associationswere observed between thigh, chest, bicipital, sub-scapular and supra-iliacskinfolds (Factor 1) and AC and BMI (Factor 2) and WHR as a third factor. Wemay conclude that factorial analyses have adequately identified three adipositypatterns in this group of women: peripheral, global and central. The strongassociation between BMI and AC demonstrates that AC could substitute with advantageBMI in population screening for obesity. The diagnosis of obesity would be moreprecise if AC, WHR and thigh skinfolds were included simultaneously.
