Índices antropométricos em escolares de um município no Sul do Brasil: análise descritiva utilizando o método LMS1

Abstract

OBJECTIVE: To describe the percentile values for body mass index (BMI), waist circumference (WC) and waist-to-height (WHtR) of children from Colombo, Brazil, and compare them with data of children from other countries. METHODS: This was a cross-sectional study with a random sample of 2,035 children aged 6-11 years. Age- and sex-specific smoothed percentiles curves for BMI, WC and WHtR were created using the LMS method. Values of 10th, 50th and 90th percentiles from Brazilian children were compared with data from other countries. RESULTS: There was a trend of increasing BMI and WC with age in both sexes. WHtR remained constant with advancing age in boys and girls. Comparison of the growth pattern among countries showed clear differences. Southern Brazil boys and girls had elevated 90th percentile values for BMI, which was similar to German children and higher than the North American and World Health Organization percentile values. However, children from this study had intermediate values for WC and WHtR in comparison to children from other countries. CONCLUSIONS: Elevated BMI values were observed among southern Brazilian children, but WC and WHtR percentile values were lower in southern Brazilian children than in children from other countries. Interventions at different levels should be made to avoid a probable increase of nutritional disorders (especially general obesity) in the next years.

Using LMS tables to determine waist circumference and waist-to-height ratios in Colombian children and adolescents: the FUPRECOL study

“…However, in the 14.0–17.9 year range, the tendency was reversed, and the girls had higher WHtR values in all percentiles. These results are in line with previous research on other sample populations [ 52 , 53 ].…”

New Reference Parameters for Body Mass Index in Children Aged Six to Ten Years

“…Over the last decades, several methodologies have been developed and implemented to establish cut-off points of anthropometric indices for children and adolescents, in order to highlight a certain growth pattern and nutritional status in pediatric populations from different countries. 21 , 22 Among them, the LMS method presented by Cole & Green 23 is a robust statistical procedure using centile values for anthropometric variables that are not normally distributed in the population. 22 …”

“…The LMS method consists of three parameters, Lambda (L), Mu (M), and Sigma (S), with L corresponding to the Box-Cox power lambda, M to the median of the values presented in a given group, and S to the coefficient of variation. The International Obesity Task Force (IOTF) 15 also adopted this methodology to propose reference values for BMI classification in children and adolescents, and Conde and Monteiro 22 used it to determine BMI cut-off points to assess the nutritional status of Brazilian children and adolescents. 17 , 21…”
