[Anthropometric characteristics of obese women before and after weight reduction]

Anthropometric changes in 53 premenopausal obese women, 25-45 year-old, after an obesity treatment, were analyzed. Before and immediately after treatment, midarm, abdomen, waist, hip, midthigh and midcalf circumferences, as well as tricipital, bicipital, suprailiac, subscapular, abdominal and calf skinfold thickness were measured. The later averaged over percentil 75th. All final measurements, except midcalf circumference, abdomen/waist and hip/midthigh indexes, were significantly lowers as compared with the initial values. Body weight decreased on average 8.9 kg, and skinfold thickness mean fell below the 75th percentile. Percentage body fat decreased 18.3%, and body mass index 11%. Initial principal component analysis results, exhibited three chief characteristics of obesity: general adiposity; trunk vs. extremity fatness, and upper vs. lower fatness. Body fat distribution pattern and body composition were modified as a result of the treatment. Therefore, the morbidity risk associated with them, was substantially reduced.
