[Cut-off points of anthropometric markers for hypertension and hyperglycemia in Argentine adults: a cross-sectional study from the 4th ENFR]
Abstract
Introduction: High waist circumference (WC), waist-to-height ratio (WHtR), and body mass index (BMI) are associated with increased cardiometabolic risk. The objective was to identify anthropometric cut-off points that allow discriminating subjects at increased risk of presenting high blood pressure and glycemia in Argentine adults.
Methods: The results of the 4th Argentine ENFR were used. Subjects aged 18 to 65 years who had blood pressure, blood glucose, and anthropometry directly measured were included (n=4254 and 1683 subjects of both sexes for high blood pressure and blood glucose, respectively). The area under the ROC curve was calculated. The optimal cut-off point was the one with the smallest difference between sensitivity and specificity. Adjusted odds ratios (aOR) were calculated for each point.
Results: In men, the cut-off points for high blood pressure were WC=91.5 cm (aOR= 3.55; 95% CI=2.97-4.24), WHtR=0.541 (aOR=3.12; 95% CI =2.61-3.73) and BMI=27.0 kg/m2 (aOR=3.04; CI95%=2.55-3.63); and for high blood glucose WC=94.5 cm (aOR=2.46; 95% CI=1.64-3.70), WHtR =0.559 (aOR=2.35; 95% CI=1.55-3.55) and BMI=28.6 kg/m2 (aOR= 3.23; CI95%=2.14-4.88). In women, for high blood pressure, WC=88.5 cm (aOR=3.57; 95% CI=2.84-4.41), WHtR=0.542 (aOR=3.45; 95% CI=2.79- 4.27) and BMI=26.7 kg/m2 (aOR=3.25; CI95%=2.64-4.02); and for high blood glucose WC=93.5 cm (aOR=4.28; 95% CI=2.72-6.75), WHtR =0.573 (aOR=3.61; 95% CI=2.31-5.66) and BMI=27.8 kg/m2 (aOR= 3.14; CI95%=2.03-4.87).
Conclusion: Argentine adults who have WC measured on the skin and are above the cut-off points identified here, have a significantly higher risk of presenting high blood pressure and hiperglycemia.
Introducción: Circunferencia de cintura (CC), índice cintura/talla (ICT) e índice de masa corporal (IMC) elevados se relacionan con mayor riesgo cardiometabólico. El objetivo fue identificar puntos de corte antropométricos que permitan discriminar a sujetos en riesgo aumentado de presentar tensión arterial y glucemia elevadas en adultos argentinos.
Métodos: Se utilizaron los resultados de la 4ta ENFR argentina. Se incluyeron sujetos de 18 a 65 años a quienes se les haya medido directamente tensión arterial, glucemia y antropometría (n=4.254 y 1.683 sujetos de ambos sexos para tensión arterial y glucemia elevadas respectivamente). Se calculó el área bajo la curva ROC. El punto de corte óptimo fue el que presentó menor diferencia entre sensibilidad y especificidad. Se calcularon odds ratios ajustados (ORa) para cada punto.
Resultados: En varones los puntos de corte para tensión arterial elevada fueron CC=91,5 cm (ORa=3,55; IC95%=2,97-4,24), ICT=0,541 (ORa=3,12; IC95%=2,61-3,73) e IMC=27,0 kg/m2 (ORa=3,04; IC95%=2,55-3,63); y para glucemia elevada CC=94,5 cm (ORa=2,46; IC95%=1,64-3,70), ICT=0,559 (ORa=2,35; IC95%=1,55-3,55) e IMC=28,6 kg/m2 (ORa= 3,23; IC95%=2,14-4,88). En mujeres, para tensión arterial elevada fueron CC=88,5 cm (ORa=3,57; IC95%=2,84-4,41), ICT=0,542 (ORa=3,45; IC95%=2,79-4,27) e IMC=26,7 kg/m2 (ORa=3,25; IC95%=2,64-4,02); y para glucemia elevada CC=93,5 cm (ORa=4,28; IC95%=2,72-6,75), ICT=0,573 (ORa=3,61; IC95%=2,31-5,66) e IMC=27,8 kg/m2 (ORa=3,14; IC95%=2,03-4,87).
Conclusión: Los adultos argentinos a quienes se les mida CC sobre la piel y se encuentren por encima de los puntos de corte aquí identificados, cuentan con un riesgo significativamente mayor de presentar tensión arterial y glucemia elevadas.
