    Obesity is defined as an excess of total body fat and may be assessed by different methods. The objective of the present study was to establish the discriminatory power of anthropometric data in determining obesity.

    To evaluate whether anthropometric methods such as arm muscle area, armfat area, Rohrer index, conicity index, and waist-to-height ratio and the commonly usedbody mass index method are suitable for obesity screening in a multiethnic paediatric pop-ulation.

    Association between nutritional status, food habits and physical activity level in schoolchildren.
    (2012) Coelho, Lorene Gonçalves; Cândido, Ana Paula Carlos; Coelho, George Luiz Lins Machado; Freitas, Silvia Nascimento de
    Objective: To analyze the relation between nutritional status, food habits and physical activity level in schoolchildren. Methods: A cross-sectional study was carried out with 661 schoolchildren, from 6 to 14 years old, enrolled in public and private schools located in the urban area of Ouro Preto, state of Minas Gerais, Brazil. A semistructured questionnaire was applied to collect data on demographic, socio-economic, anthropometric and level of physical activity variables. Schoolchildren were classified according to criteria for body mass index by age, body fat percentage and physical activity level, respectively. Dietary data were collected through a validated food frequency questionnaire specific for children and adolescents. Food consumption was evaluated according to an adaptation of the Recommended Foods Score, whose objective is the assessment of overall diet quality with a focus on healthy food consumption. Results: We observed high frequency of overweight according to body mass index per age (20.1%) and body fat percentage (22.8%), as well as physical inactivity (80.3%) among schoolchildren. We also found low scores on the Recommended Foods Score in 77.2% of students. There was no significant relation between overweight and physical inactivity or food consumption (p > 0.05). Conclusion: Schoolchildren had a high frequency of overweight, which, alone, was not associated with the high physical inactivity and the low quality diet observed. Therefore, more studies should be performed to identify other factors besides those already described, which may be influencing overweight in this population.

    Anthropometric methods for obesity screening in schoolchildren; the Ouro Preto Study.

    Background and aims: Childhood obesity is increasing dramatically in last decades. To evaluate the usefulness of body mass index (BMI), skinfold thickness (ST), waist circumference (WC), and foot-to-foot bioelectrical impe - dance (BIA-FF) for screening for obesity in mixed-race population, using the tetrapolar bioelectrical impedance (BIA-T) technique as reference method. Methods and results: A cross-sectional-based population study was performed in the city of Ouro Preto, Brazil, in 2006. Schoolchildren aged 6-15 years (n = 788) was randomly selected according to age and sex stratified by the proportion of students in each schools of the city. Nonparametric receiver operating characteristic (ROC) analysis was used to define the sensitivity and specificity for each method studied using the tetrapolar method as reference. The BMI and the BIA-FF were the most suita - ble for adiposity screening in pre-pubertal and pubertal stages because they present a better balance between sensitivity and specificity, and smaller misclassification. For post-pubertal boys, the BF-ST-D was the best body fat assessment method. Conclusion: The results suggest that BIA-FF and BMI are choice methods for obesity screening in mixed population and that the method choice for body fat screening must be done according to sexual maturity of boys and girls. The present study demonstrates the need to perform studies in wider mixed-race population to determine anthropometric parameters and to examine the predictive ability of methods and cut-offs here elucidated in the development of obesity.
