HIPERTENSÃO ARTERIAL NO MUNICÍPIO DO HUAMBO: PREVALÊNCIA, FACTORES DE RISCO E CONTROLE NAS UNIDADES SANITÁRIAS (JANEIRO A ABRIL DE 2025)

Hypertension is the main risk factor for cardiovascular diseases and is associated with high overall mortality, especially in low- and middle-income countries. It is estimated that more than 1.3 billion people live with hypertension, most of them in resource-limited settings where diagnosis, treatment, and control remain insufficient. In Angola, the prevalence is between 33% and 38%, but there are still few studies that delve into the factors associated with the control of the disease. This study aimed to determine the prevalence of hypertension and analyze sociodemographic, behavioral and clinical factors associated with its control in health units in the Municipality of Huambo, between January and April 2025. This is an observational, cross-sectional, quantitative study, carried out in three health units with 1,725 adult participants. Data collection involved a structured questionnaire and blood pressure measurement. Statistical analysis, processed in SPSS 27.0, included descriptive statistics, Pearson's correlation, chi-square and binary logistic regression, adopting p<0.05. The results showed a prevalence of hypertension of 48%, with 56% of patients not having adequate blood pressure control. Age and adherence to treatment were identified as factors associated with control, while schooling showed a significant relationship with treatment adherence. In addition, habits such as high salt consumption, smoking, alcohol use, and sedentary lifestyle were frequent and strongly related to the disease. It is concluded that educational interventions and lifestyle changes, combined with drug treatment, are essential to improve hypertension control.
