    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.

  • Prevalence and factors associated with inadequate intake of fruits and vegetables in a population from Northern Angola
    Publication . Morais, Humberto; Cupessala, Vizé Preciosa; Pedro, João Mário; Brito, Miguel; Gonçalves, Mauer A. A.
    Background: The World Health Organization recommends a minimum intake of 400 g or five servings of Fruits and Vegetables (FVs) per day for the prevention of chronic diseases. Objective: The present study aims to describe the prevalence and factors associated with inadequate FV intake in a sample of Angolan adults who participated in the CardioBengo study. Methods: It is a subset analysis of CardioBengo, a community-based cross-sectional observational study conducted in the Dande Municipality, Bengo Province, Angola. Results: The sample included 2161 individuals aged 18 to 84, with 64.1% being women. 57.2% of participants were below high school, and only 3.1% attended higher education. 61.7% were married, and 48.3% had a monthly income below 150 USD. The prevalence of insufficient FV consumption in the sample was 86.2%. It was observed that female gender, low education level, and the age group of 20-29 years were associated with inadequate FV intake (p = 0.010, p = 0.001, and p = 0.006, respectively). Conclusion: There was no association between FV consumption and cardiovascular risk factors. A prevalence of FV consumption well below current recommendations was identified. The identified risk factors can serve as a strategy to increase FV consumption in this population.
