Distribuição de valores de medidas antropométricas e avaliação do estado nutricional de escolares de 7 a 10 anos de idade, da cidade de Santos - SP
Aim: Describe the distribution of anthropometric measures and indices, and the nutritional status in schoolchildren between 7 and 10 years old. Methods: Were evaluated 10,822 schoolchildren of public and private schools from the city of Santos -SP, 5,211 boys and 5,611 girls, corresponding to 52.17%...

| Sumario: | Aim: Describe the distribution of anthropometric measures and indices, and the nutritional status in schoolchildren between 7 and 10 years old. Methods: Were evaluated 10,822 schoolchildren of public and private schools from the city of Santos -SP, 5,211 boys and 5,611 girls, corresponding to 52.17% of schoolchildren in this age range. The measures were: weight, height and skin fold thickness; and the calculated indices were: body mass index, sub scapular/triceps index, sum of five skin folds, and body fat percentage. The nutritional status was estimated by body mass index for age and gender, using CDC (2000) diagnostic criteria, where 5th percentile is a cutoff point for underweight, 85th percentile is cutoff for overweight, and 95th percentile is cutoff for obesity. The prevalence of nutritional status was also calculated by Cole et al. (2000) diagnostic criteria, adopted by the International Obesity Task Force (IOTF), for comparison the predictive values of the two criteria in relation to body fat percentage. Percentile tables were constructed for all studied variables. Results: The total prevalence of underweight, overweight and obesity was 3.7%, 15.7% and 18.0%, respectively. In the public schools, the prevalence of underweight was 4.5% for boys and 4.2% for girls; and in the private schools, 3.2% for boys and 2.7% for girls. The prevalence of overweight was 13.7% for boys and 14.8% for girls, in the public schools. In the private schools was 17.7% for boys and 22.2% for girls. Obesity was prevalent in 16.9% of boys and 14.3% of girls, in public schools. In the private schools, 29.8% of boys and 20.3% of girls were diagnosed as obese. The sensibility and specificity analysis for two diagnostic criteria showed that the best results of overweight and obesity estimative for boys was obtained by CDC (2000). For girls, CDC showed the best diagnostic results in 9 and 10 years old, and did not present difference of IOTF in other ages. In relation to body fat distribution, 23.6% of boys and 26.7% of girls presented abdominal obesity; among obese children, 46.2% of boys and 59.0% of girls showed this status. Conclusions: The prevalence of underweight was comparable of those in developed countries; overweight and obesity were higher than other studies conducted in Brazil, being more prevalent in private schools. Elevated proportion of children with abdominal obesity was found. Although private schools have more obese children, abdominal obesity was not different between public and private schools. The diagnostic criteria that showed best efficiency was CDC, presenting higher positive and negative predictive values, in the majority of the studied ages, in both genders. The normative values for anthropometric measures and body indices, in percentile tables, associated with known diagnostic criteria, can enhance the understanding about the variables behavior related to the studied population nutritional status. |
