Prevalência e fatores relacionados ao descontrole da pressão arterial em pacientes hipertensos

Abstract

Objectives: To describe the prevalence of uncontrolled blood pressure (BP) and related factors among hypertensive patients treated in Primary Health Care (PHC). Methods: A cross-sectional study was conducted in Marau, Rio Grande do Sul, including adults and older adults seen in PHC in 2019. Data were collected from electronic medical records and included sociodemographic, health, and behavioral characteristics. The prevalence of uncontrolled BP measurements (dependent variable) was calculated with a 95% confidence interval (95% CI). The distribution of out-of-target BP measurements according to exposure (independent) variables was also analyzed using the chi-square test, with a type I error of 5%. Results: In the sample (n=1,245), the prevalence of uncontrolled blood pressure measurements was 36.1% (n=1,245; 95% CI: 33.5–38.8%), with a statistically significant difference in relation to age (44.0% among adults; p=0.002) and overweight/obesity (39.0% among those with overweight/obesity; p<0.01), as well as a borderline statistical difference regarding alcohol consumption (53.6% among alcohol consumers; p=0.05). In addition, the prevalence of systemic arterial hypertension (SAH) in the sample was 44.2% (95% CI: 42.5–45.9%), and the mean blood pressure among hypertensive individuals was 128.03 mmHg (17,93) for systolic BP and 79.98 ±mmHg (11,30) for diastolic BP. Conclusions: The prevalence of uncontrolled BP ±measurements is high among hypertensive adults and older adults in the city of Marau, RS, especially among individuals who are overweight/obese, adults, and alcohol consumers.
