“…Já Tuan et al [10] e Huxley et al [33] não encontraram diferenças entre IMC, CC, RCQ e RCE na capacidade de predição da HAS em chineses e em indivíduos de diferentes países da Ásia e do Pacífico. Em estudo de Silva et al [9], IMC, CC e RCE apresentaram a mesma capacidade em discriminar a HAS em mulheres de uma cidade do sul do Brasil.…”

“…O efeito vasodilatador da insulina, o qual é mediado pelo óxido nítrico, está comprometido em obesos e hipertensos, portadores de diabetes mellitus tipo 2, o que poderia contribuir ainda mais para a elevação da PA [1]. Huxley et al [33] evidenciaram que RCQ ≥0,84 seria o melhor ponto de corte para discriminar a HAS em mulheres asiáticas, valor igual ao encontrado neste estudo em mulheres quilombolas.…”

“…Diversos trabalhos têm utilizado as curvas ROC procurando identificar os melhores pontos de corte de diferentes parâmetros antropométricos para a predição da HAS em diferentes populações [8][9][10][33][34][35], em virtude da magnitude dessa doença e de que os pontos de corte propostos pela OMS foram estabelecidos para caucasianos [14]. Nesse sentido, destaca-se que o presente estudo foi o primeiro que visou identificar o melhor preditor antropométrico de HAS em mulheres de comunidades remanescentes de quilombos.…”

RESUMOOBJETIVOS: Investigar a associação entre parâmetros antropométricos e hipertensão arterial sistêmica e identificar os melhores preditores antropométricos dessa condição em mulheres afrodescendentes, de comunidades remanescentes de quilombos. MÉTODOS: Estudo transversal realizado com mulheres quilombolas do Estado de Alagoas. Foram investigados pressão arterial, parâmetros antropométricos (índice de massa corporal, circunferência da cintura, razão cintura-quadril, razão cintura-estatura, índice de conicidade, gordura corporal), variáveis sociodemográficas, tabagismo e paridade. As associações entre parâmetros antropométricos e hipertensão arterial sistêmica foram averiguadas por meio da regressão de Poisson com ajuste robusto da variância. A capacidade desses parâmetros em predizer a presença de hipertensão arterial sistêmica foi analisada por meio de curvas ROC (Receiver Operating Characteristic). RESULTADOS: Foram avaliadas 1.553 mulheres, com idades entre 20 e 59 anos. A prevalência de hipertensão arterial sistêmica foi 35,8% e a de excesso de peso foi 48,5%. A presença de hipertensão arterial sistêmica associou-se a índice de massa corporal, circunferência da cintura, razão cintura-quadril, razão cintura-estatura e gordura corporal, mesmo após o ajuste para idade, classe socioeconômica e tabagismo. A partir das curvas ROC, foram encontrados os seguintes pontos de corte: índice de massa corporal ≥26,2 kg/m², circunferência da cintura ≥81,6 cm, razão cintura-quadril ≥0,84, razão cintura-estatura ≥0,54, índice de conicidade ≥1,20 e gordura corporal ≥35,4%. Gordura corporal, razão cintura-quadril e razão cintura-estatura apresentaram igual capacidade em predizer a hipertensão arterial sistêmica. CONCLUSÕES: Todos os indicadores de obesidade global e os de obesidade central, excetuando-se o índice de conicidade, associaram-se à hipertensão arterial sistêmica nessa amostra de mulheres afrodescendentes quilombolas. Os melhores preditores antropométricos de hipertensão arterial sistêmica foram porcentagem de gordura corporal, razão cintura-quadril e razão cintura-estatura. Essas medidas tiveram igual, embora baixo, poder discriminatório para a presença de hipertensão arterial sistêmica nessa população. DESCRITORES:Afro-americanos; etnia e saúde; gordura abdominal; obesidade; pressão arterial; curva ROC. ABSTRACTAIMS: To determine the association between anthropometric parameters and systemic arterial hypertension and to identify the best anthropometrics predictors of this disease in afro-descendant women from remaining quilombo communities. METHODS: A cross-sectional study was conducted with quilombola women from Alagoas State. Blood pressure, anthropometric parameters (body mass index, waist circumference, waist-to-hip ratio, waist-to-height ratio, conicity index, body fat), sociodemographic variables, smoking and parity were investigated. The associations between anthropometric parameters and systemic arterial hypertension were investigated using Poisson regression with robust variance adjustment. The ability...

Background: Two popular indicators for detecting obesity are body mass index (BMI) and waist-to-hip ratio (WHR). Objectives: The primary purpose of this study was to examine the agreement between the BMI and WHR classifications in diagnosing obesity among adult Iranians by using cutoff points of world health organization (WHO) gold standards. The secondary purpose was to estimate suitable cutoff points for BMI and WHR for various sex and age-groups. Methods: The study was cross-sectional. The data were obtained from 13,691 females and 5,675 males between 2009 and 2014. Body composition indices were measured by bioelectrical impedance method (BIA). Percentage of body fat (PBF), total fat (TF), BMI, and WHR were determined. Data analysis included t-test, chi-square test, receiver-operating characteristic (ROC) curves, Fisher's r-to-z transformation, linear regression, and Hanely formula. Results: In the WHR classification, nearly 78% of obese subjects had been wrongly classified as non-obese, but only 15.8% of obese females were wrongly classified as non-obese. The WHR was ineffective in detecting obesity among males between 20 and 39 years old. By the BMI classification, 42.5% of obese males had been wrongly classified as non-obese, but it was effective in detecting obesity in females between the ages of 20 and 39 years. Conclusions:The suitable BMI cutoff points for detecting obesity for adult Iranians are 27.7 in all subjects, 27.7 in females, and 27.3 in males, which are all less than the BMI of 30 recommended by the WHO. On the basis of the WHR, they are 0.88 and 0.83 for males and females, respectively, which are less than the recommended cutoff points for Europeans but similar to those Eastern Asians.

Is central obesity a better discriminator of the risk of hypertension than body mass index in ethnically diverse populations?

Abstract: Blood pressure is similarly associated with each of the four measures of overweight chosen, but the associations were stronger among Asians. WHR has advantages in terms of consistency of thresholds for hypertension across ethnic groups in the Asia-Pacific.
