This longitudinal study aims at providing initial data regarding the nutritional condition of 30 children and adolescents enrolled in a multiprofessional follow-up program. Analyzing their anthropometric data, body composition (percentage of fat), laboratory (seric cholesterol and fractions) and physical exams (stage of puberal development), alimentary survey (average daily routine intake) and previous treatments. The group was composed by 17 girls and 13 boys, aged in average 13 years, with average weight 91,8kg and average height 161,6cm. Body fat (measured by bone densitometry) varied from 43,8 (boys) to 49,6)girls, as an average. As for puberal development (TANNER) 50% were above stage 4, 39% between 2nd and 3rd stages and 10,7% were pre-puberty. Among the studied subjects, 66% presented altered levels of cholesterol and fractions (2° American Heart Position Statement Circulation). 64,7% underwent treatments for weight reduction (body mass rate: 38,26 kg/m2), while the others who did not underwent treatment presented with average body mass rate 28,75kg/m2. Average caloric daily intake was 3098 kcal(40,23% as fat). In subjects who underwent treatments the average caloric value was 3252 kcal, while those who went on without treatment average intake was 2787 kcal (in average). It was also observed that there were major lipid alterations in individuals who underwent drastic treatments (79%). These findings suggest the need for specialized attention aiming at the maintenance and/or gradual long term weight loss, so that growth and development are not impaired.
