Key result
Sociodemographic disparities link to ~38% hypertension prevalence, concentrated heavily among men and older adults.
Why the study?
Arterial hypertension is a leading cause of healthcare consultations, hospital admissions, and mortality with a 30-35% prevalence in Brazil, prompting evaluation of its local prevalence and association with sociodemographic factors.
Are sociodemographic factors (age, gender, education level, income) associated with the prevalence of arterial hypertension in a population-based sample in Sorocaba-SP, Brazil?

Are sociodemographic factors (age, gender, education level, income) associated with the prevalence of arterial hypertension in a population-based sample in Sorocaba-SP, Brazil?
This population-based survey in Sorocaba, Brazil found a 38.39% prevalence of arterial hypertension with significant sociodemographic disparities, highlighting the need for targeted public health policies for socially vulnerable groups, men, and the elderly.

Prevalence data warrant no practice change; leaves open causal effects of disparities on hypertension.
Background: Arterial Hypertension (AH) is a leading cause of morbidity and mortality worldwide. Its prevalence among adults and the elderly is high globally and between 30-35% in Brazil. It is a primary reason for healthcare consultations, hospital admissions, and mortality. Objectives: This study aimed to evaluate the AH prevalence and to investigate its association with sociodemographic factors. Methods: A population-based, cross-sectional study on a cluster sample of 1,080 individuals. The analysis evaluated age, gender, education level, income. The statistical model estimated prevalence ratios (PR), 95% confidence intervals, while a concentration curve assessed sociodemographic inequalities. Results: An overall prevalence of 38.39% was observed, along with a significant association between AH and gender, age, education level, and income. The concentration curve revealed a distribution of AH higher among men and the elderly, concentration index = -0.31. Conclusions: These findings underscore the need for public policies aimed at reducing health inequalities and strategies for prevention, diagnosis, and control of AH for populations facing greater social vulnerability.

Gianini et al. (2026) conducted a cross-sectional in Arterial Hypertension (n=1,080). Sociodemographic factors (age, gender, education level, income) was evaluated on Prevalence of arterial hypertension and sociodemographic inequalities (Concentration index -0.31). Sociodemographic factors were associated with a 38.39% hypertension prevalence, disproportionately affecting men and the elderly.
