• Prehypertension
• Vulnerable Groups
• Cross-Sectional Studies

Arterial prehypertension is a precursor of arterial hypertension and a risk factor for cardiovascular diseases. Vulnerable populations are more prone to this condition due to difficulties in access to health services. A previous study in quilombola communities (descendants of African slaves) reported a high prevalence of arterial hypertension. The current study aimed to estimate the prevalence of arterial prehypertension in quilombolas and to assess associated factors. This was a cross-sectional population-based study in individuals 18 years and older. Prehypertension was defined as arterial systolic pressure >= 121mmHg and < 140mmHg and/ or diastolic >= 81mmHg and < 90mmHg. Multivariate Poisson regression with robust variance was used. Population-attributable fractions (PAF) were also calculated for the modifiable associated factors. Prevalence of prehypertension was 55% (95% CI: 50.2-59.7). Male gender (PR = 1.54), 1 to 4 complete years of schooling (PR = 1.44), and BMI classified as overweight (PR = 1.39) and obesity (PR = 1.87) showed positive association with prehypertension. Higher attributable fractions were observed in individuals with 1 to 4 years of schooling (13.7%) and those classified as overweight (9.35%) and obese (4.6%). Prevalence of prehypertension in quilombola communities was high, and its identification may allow screening and awareness-raising in a group with increased risk of cardiovascular disease and progression to full-blown hypertension. The study highlights the need for broad access to health services and specific measures for orientation, prevention, and health promotion in this population.
