Resumo(s)
Obesity, particularly when it is centrally located, is an important risk factor for the development of cardiovascular diseases. This study aimed to assess the relationship between waist circumference and the presence of diabetes mellitus, hypertension, and dyslipidaemia. A community-based cross-sectional study was conducted as a sub-analysis of CardioBengo in the municipality of Dande, Bengo Province, involving 2,244 individuals aged 18– 84 years. The study included a structured questionnaire and the collection of sociodemographic, anthropometric, hemodynamic, and biochemical data. Analyses were carried out using correlation methods, the construction of ROC (Receiver Operating Characteristic) curves, and the determination of optimal cut-off points according to the Youden index. Waist circumference was positively associated with metabolic risk factors, particularly hypertension, in both sexes. It demonstrated moderate sensitivity and specificity (area under the curve (AUC): 0.725 in men and 0.612 in women). Waist circumference also proved to be a moderate predictor of diabetes mellitus (AUC: 0.648 in men and 0.596 in women) and hypercholesterolaemia (AUC: 0.673 in men and 0.612 in women), with cut-off points varying between 71.5 cm and 89 cm depending on gender. For hypertriglyceridaemia, however, the association was weak (AUC: 0.557 and 0.503). Waist circumference can be used as an indicator of the risk of developing metabolic factors, highlighting its usefulness in predicting hypertension in the Angolan population.
