Insights
A 1987 study in Brazil found high blood pressure prevalence (32% men, 25% women). This hypertension risk increased with age, particularly in lower socioeconomic groups, though associated odds ratios were small.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Context:
- A 1987 cross-sectional study was conducted in Araraquara County, São Paulo State, Brazil.
- The study investigated the prevalence of high blood pressure (hypertension) in a representative sample of the population.
Purpose:
- To determine the prevalence of hypertension in adults aged 15-74 years.
- To identify demographic and socioeconomic factors associated with hypertension in this population.
Summary:
- The study included 1,199 participants (533 men, 666 women).
- High blood pressure prevalence was 32.0% in men and 25.3% in women.
- Hypertension prevalence increased with age, peaking in the 40s for men and 50s for women.
- Higher prevalence was observed in individuals of mulatto and black ethnicity, the obese, those with lower family income, lower educational attainment, and less well-remunerated jobs.
- Logistic regression analysis indicated small odds ratios for these risk factors, suggesting potential confounding or measurement issues.
Impact:
- Highlights the significant public health burden of hypertension in Brazil.
- Identifies key demographic and socioeconomic disparities in hypertension prevalence.
- Suggests the need for further investigation into the complex interplay of risk factors and their accurate measurement in hypertension research.
Abstract:
The results of a cross-sectional (prevalence) study of high blood pressure, carried out in 1987 in Araraquara County in the north of S. Paulo State, Brazil are presented. The group studies numbered 1,199 people, including 533 men and 666 women, of from 15 to 74 years of age. The results show a high prevalence of the disease (32.0% for men and 25.3% for women), with a tendency to increase with age, up to the 40's (men) and the 50's (women). There was also a greater percentage of hypertensives in the mulatto and black groups, in the obese, and among those of lower family income, with a lower level of schooling and with less well remunerated jobs. However, the logistic regression showed very small odds ratios associated with these risk factors, which could be attributed to the way these factors were considered.
