“…Body fat percentage was calculated using Slaughter's equations, which showed the best agreement with total body fat percentage measured by DXA in adolescent population. 12 Identification of sexual maturation was assessed by a trained physician according to Tanner and Whitehouse. 13 PA was objectively measured by accelerometry (Actigraph GT1M, Pensacola, FL, USA).…”

We examined the association between the FTO rs9939609 polymorphism and serum leptin concentrations in adolescents. The FTO rs9939609 polymorphism was genotyped, and fasting serum leptin and insulin were measured in 655 European adolescents (365 females) aged 14.6 ± 1.2 years. We measured weight, height, triceps and subscapular skinfolds and waist circumference, and body fat percentage was calculated. Sex, pubertal status, center, physical activity (accelerometry), total or central adiposity and serum insulin concentrations were entered as confounders in the analyses. The minor A allele of the FTO rs9939609 was significantly associated with higher serum leptin concentrations independently of potential confounders including adiposity ( þ 3.9 ng ml À1 per risk allele (95% confidence interval: 2.0, 5.9); adjusted Po0.001). These findings could link the FTO gene with serum leptin and consequently with the control of energy balance. Leptin could be a possible intermediary contributing to the association between the FTO rs9939609 polymorphism and adiposity.

Objective: To assess the nutritional status, food intake and physical activity patterns in schoolchildren attending 5th and 6th grade in basic schools from different socio-economic levels in the metropolitan region of Santiago. Design: Cross-sectional study in children 5th and 6th grade of eighteen basic schools in the metropolitan region of Santiago. Setting: Boys and girls aged 9-12 years from basic schools were evaluated in terms of physical capacity. An anthropometric evaluation was also performed which included weight, height and triceps and subscapular skinfold thicknesses. Food intake was evaluated by a 24 h recall, socio-economic level by the ESOMAR method and physical activity by a questionnaire. Subjects: Boys and girls aged 9-12 years (n 1732). Results: The average prevalence of overweight and obesity was 40 %, with the highest prevalence in males and those from lower socio-economic level. A majority (64 %) of the children had a low level of physical activity. A higher intake of fat and protein and a higher intake of carbohydrate were found in the higher and lower socio-economic levels, respectively. Both males and females showed adequacy greater than 75 % in macronutrient intake except for fibre, with both groups showing a deficit in the consumption of fruits, vegetables, legumes, fish and milk products according to Chilean recommendations. Conclusions: A high prevalence of malnutrition by excess was observed in both sexes and a better eating and physical activity pattern was seen in children from higher socio-economic level.

“…The most precise methods for assessing body composition, as well as local distribution of fat mass and fat-free mass are dual X-ray absorptiometry (DXA), 3 underwater weighing, 4 air displacement plethysmography, computer tomography and nuclear magnetic resonance. 5 However, these techniques are expensive and require sophisticated laboratory settings, which make them inappropriate to use in large epidemiological studies.…”

The Healthy Lifestyle in Europe by Nutrition in Adolescence Study aims to describe total body fat percentage and anthropometric indices of body fat distribution in European adolescents. Objective: To describe the standardization process and reliability of anthropometric and bioelectrical impedance analysis (BIA) measurements. We examined both intra-and interobserver errors for skinfolds, circumferences and BIA. Methods: For the intraobserver error assessment, first of all, 202 adolescents in the pilot study (110 boys, 92 girls, aged 13.64 ± 0.78 years) were assessed. For the second intraobserver and interobserver assessments, 10 adolescents were studied (5 boys and 5 girls). Results: The pilot study's intraobserver technical errors of measurement (TEMs) were between 0.12 and 2.9 mm for skinfold thicknesses, and between 0.13 and 1.75 cm for circumferences. Intraobserver reliability for skinfold thicknesses was greater than 69.44% and beyond 78.43% for circumferences. The final workshop's intraobserver TEMs for skinfold thicknesses and circumferences were smaller than 1; for BIA resistance TEMs were smaller than 0.1 O and for reactance they were smaller than 0.2 O. Intraobserver reliability values were greater than 95, 97, 99 and 97% for skinfold thicknesses, circumferences, BIA resistance and reactance, respectively. Interobserver TEMs for skinfold thicknesses and circumferences ranged from 1 to 2 mm; for BIA they were 1.16 and 1.26 O for resistance and reactance, respectively. Interobserver reliability for skinfold thicknesses and circumferences were greater than 90%, and for BIA resistance and reactance they were greater than 90%. Conclusions: After the results of the pilot study, it was necessary to optimize the quality of the anthropometric measurements before the final survey. Significant improvements were observed in the intraobserver reliabilities for all measurements, with interobserver reliabilities being higher than 90% for most of the measurements.
