2000/2012 - Associação entre circunferência da cintura e índice de massa corporal de mulheres brasileiras: PNDS 2006 Association between waist circumference and body mass index of brazilian women: NDHS 2006
O objetivo do estudo foi analisar a associação entre a circunferência da cintura (CC) e o índice de massa corporal (IMC) de mulheres brasileiras em idade fértil, estudadas na última Pesquisa Nacional de Demografia e Saúde (PNDS), no ano de 2006. Esse estudo é um recorte da PNDS, a qual é um estudo seccional, de base domiciliar. O estado nutricional foi avaliado através do IMC e da CC, considerando-se excesso de peso IMC ≥ 25 Kg/m2 e CC de risco ≥ 80 cm. Para a avaliação da significância estatística, foi utilizada Regressão de Poisson para identificar os fatores associados à CC de risco em mulheres com e sem excesso de peso, apresentando-se o valor p correspondente ao teste de Wald para heterogeneidade ou tendência linear. Das 14.101 mulheres estudadas, 45,8% apresentaram excesso de peso e 55,5% CC de risco. Em relação à associação entre IMC e CC, constatou-se que 23,5% das mulheres sem excesso de peso apresentavam CC de risco (p<0,001). Após análise estratificada pelo IMC, a prevalência de CC de risco entre as mulheres sem excesso de peso foi maior nas regiões Nordeste, 26,0%, e Sudeste, 24,5%, e menor na região Sul, 18,5%. Conclui-se que as medidas antropométricas IMC e CC devem ser empregadas concomitantemente, uma vez que a utilização isolada dessas medidas pode desprezar indivíduos com risco para diversas patologias.

Abstract:
The aim of this study was to evaluate the association between waist circumference (WC) and body mass index (BMI) of Brazilian women of childbearing age studied in the last National Demographic and Health Survey (NDHS), in 2006. This study is an excerpt of the NDHS, which is a cross-sectional study home-based. The nutritional status of women was assessed by WC and BMI, considering overweight BMI ≥ 25 Kg/m2 and WC risk ≥ 80 cm. To evaluate the statistical significance, Poisson Regression was applied to identify factors associated with WC risk in women with or without overweight, presenting the p-value corresponding to the Wald test for heterogeneity or linear trend. Of the 14,101 women studied, 45.8% were overweight and 55.5% at WC risk. Regarding the association between BMI and WC, it was found that 23.5% of women who were not overweight showed WC risk (p<0.001). After a stratified analysis by BMI, the prevalence of WC risk among women without overweight was greatest in the Northeast, 26.0%, and the Southeast, 24.5%, while the South region presented the lowest prevalence, 18.5%. It follows that the anthropometric measures WC and BMI should be used concomitantly since the single use of these measures may disregard individuals at risk for various diseases.
