Objective: to investigate the association between hypertension and anthropometric indicators of central obesity, obtained from two anatomical sites in older adults.
Methodology: cross-sectional study that involved 145 older adults, from whom socioeconomic and demographic data and anthropometric indicators of central obesity (waist circumference [CC] and abdominal circumference [CA]) were obtained, which were considered independent variables. A logistic regression model was used to analyze associations and for the discriminatory power of the cut-off points of the hypertension anthropometric indicators, receiver operating characteristic (ROC) curve was performed. Comparisons were made between ROC curves, with the aim of identifying significant differences in the discriminatory power of the anthropometric indicators studied.
Results: out of the 145 individuals, 79 were females (54%) and 66 males (46%). Results showed a high prevalence of arterial hypertension in men (69,7%) and women (73,4%). Both CC and CA were significantly associated with hypertension in both genders. Parameters of the ROC curve revealed that both anthropometric indicators of central obesity exhibit good discriminatory power for hypertension in the studied population. The cut-off point for CC was > 83,2 cm for men and > 82,6 cm for women; while for CA it was > 85,1 cm and > 85,4 cm for men and women, respectively.
Conclusion: CA and CC are significantly associated with hypertension in both genders, and there is no superiority between them to predict hypertension in the elderly population.
Objetivo: investigar la asociación entre hipertensión e indicadores antropométricos de obesidad central, obtenidos de dos sitios anatómicos en adultos mayores.
Metodología: estudio transversal que incluyó a 145 adultos mayores, de los cuales se obtuvieron datos socioeconómicos y demográficos e indicadores antropométricos de obesidad central (circunferencia de cintura [CC] y circunferencia abdominal [CA]), que fueron considerados variables independientes. Se utilizó un modelo de regresión logística para analizar las asociaciones y para el poder discriminatorio de los puntos de corte de los indicadores antropométricos de hipertensión, se realizó curva de receiver operating characteristic (ROC). Se hicieron comparaciones entre las curvas ROC, con el objetivo de identificar diferencias significativas en el poder discriminatorio de los indicadores antropométricos estudiados.
Resultados: de los 145 individuos 79 eran del sexo femenino (54 %) y 66 del masculino (46 %). Los resultados mostraron una alta prevalencia de hipertensión arterial en hombres (69,7 %) y mujeres (73,4 %). Tanto CC como CA se asociaron significativamente a la hipertensión en ambos sexos. Los parámetros de la curva ROC revelaron que ambos indicadores antropométricos de obesidad central exhiben un buen poder discriminatorio para la hipertensión en la población estudiada. El punto de corte para la CC fue > 83,2 cm para hombres y de > 82,6 cm para mujeres; mientras que para CA fue > 85,1 cm y > 85,4 cm para hombres y mujeres, respectivamente.
Conclusión: CA y CC están significativamente asociadas a la hipertensión en ambos sexos, y no hay superioridad entre ellas para predecir la hipertensión en la población anciana.
Objetivo: investigar a associação entre hipertensão e indicadores antropométricos de obesidade central obtidos de dois sítios anatômicos em idosos.
Metodologia: estudo transversal incluindo 145 idosos, dos quais foram obtidos dados socioeconômicos e demográficos e indicadores antropométricos de obesidade central (circunferência de cintura [CC] e cirfunferência de abdominal [CA]), que foram considerados como variáveis independentes. Um modelo de regressão logística foi utilizado para analisar as associações, além do poder discriminatório e os pontos de corte para a hipertensão dos indicadores antropométricos, que foram obtidos a partir dos parâmetros da curva Receiver Operating Characteristic (ROC). Comparações entre as curvas ROC foram realizadas, objetivando identificar diferença significativa no poder discriminatório dos indicadores antropométricos estudados.
Resultados: Entre os 145 indivíduos, 79 eram do sexo feminino (54 %) e 66 do masculino (46 %). Os resultados mostraram uma alta prevalência de hipertensão arterial entre homens (69,7 %) e mulheres (73,4 %). Tanto a CA quanto a CC foram associadas à hipertensão em ambos os sexos.de maneira significativa. Os parâmetros da curva ROC indicaram que ambos os indicadores antropométricos da obesidade central exibiram um bom poder discriminatório para a hipertensão na população estudada. O ponto de corte para a CC foi > 83,2 cm para homens e > 82,6 cm para mulheres, enquanto para CA foi > 85,1 cm e > 85,4 cm para homens e mulheres, respectivamente.
Conclusão: as CA e CC estão significativamente associadas à hipertensão em ambos os sexos e não há superioridade entre elas para prever a hipertensão na população idosa.
