Razão cintura/quadril como preditor de hipertensão arterial

Abstract

This study aims to define cut-off points for the waist:hips girth ratio (WHR), using arterial hypertension as the outcome. The data refer to 3,282 individuals over twenty years of age examined in a survey conducted in the municipality of Rio de Janeiro in 1995-1996, using a two-stage sample. Sixty census tracts were drawn initially; subsequently, 34 households were selected systematically from each tract. Stature, weight, waist and hips girths, and blood pressure were measured in the households. The criterion for hypertension was a systolic blood pressure of ( 140 mmHg or diastolic pressure of ( 90 mmHg, or use of medication to reduce blood pressure. The sensitivity and specificity of different cut-off points for WHR were calculated in the prediction of arterial hypertension according to sex, age, and presence of overweight, classified according to World Health Organization guidelines. The best cut-off points for WHR were 0.95 for men and 0.80 for women. Compared to the waist:stature ratio and waist circumference, the WHR proved more capable of predicting arterial hypertension and less correlated with body mass index.

“…In a study performed with obese subjects (15) , it was seen that the WHR increase was not associated with higher pressure levels. However, other studies (16) concluded that WHR is a complementary index to Body Mass Index in the evaluation of obesity and its metabolic changes and that the increased WHR is correlated to an adverse lipidic profile in hypertensive patients. In recent years, a special interest in the study of the association between the skin folds and blood pressure in children and teenagers is emerging.…”

“…Regarding waist circumference, the evidence that the central deposition of fat is an important marker of the risk for chronic diseases, including hypertension, has been constantly reported in different studies (16) . The ratio between waist and hip circumference measures (WHR), characterizing the central distribution of fat, has been used to identify the subjects at higher cardiovascular risk (15,17) .…”

Acurácia da circunferência da cintura e da relação cintura/quadril como preditores de dislipidemias em estudo transversal de doadores de sangue de Cuiabá, Mato Grosso, Brasil

“…No Brasil, poucas investigações avaliaram a associação entre indicadores antropométricos de localização de gordura e desfechos que se relacionam às doenças cardiovasculares 19,20,21,22,23 . Dentre esses estudos, apenas um 21 avaliou o melhor ponto de corte para a relação cintura/quadril em relação à hipertensão arterial, encontrando o valor 0,95 para homens, portanto, abaixo daquele preconizado pela OMS e pró-ximo ao observado no nosso estudo, o que confirma a inadequação do uso de pontos de corte definidos para populações caucasianas quando se trata de avaliar a população brasileira.…”

Influência do excesso de peso corporal e da adiposidade central na glicemia e no perfil lipídico de pacientes portadores de diabetes mellitus tipo 2

“…Vários estudos têm sugerido que a variação anatômica da distribuição da gordura corporal é um indicador mais importante de complicações metabólicas do que a massa corporal total (7)(8)(9)(10). A obesidade visceral resulta em inúmeras modificações fisiopatológicas, que podem resultar em diferentes graus de resistência à insulina.…”
