Insights
Arterial hypertension (AH) affects many adults, with a high prevalence of 32.7% found in Firminopolis, Brazil. Higher Body Mass Index (BMI), waist circumference (WC), and age correlated with AH, while education showed a protective effect.
Area of Science:
- Cardiology and Public Health
- Epidemiology
- Preventive Medicine
Context:
- Arterial hypertension (AH) is a significant global health issue, characterized by high rates of undiagnosed cases and treatment nonadherence.
- Brazil faces a substantial burden of cardiovascular diseases, making local prevalence studies crucial for targeted interventions.
Purpose:
- To determine the prevalence of arterial hypertension (AH) in the adult population of Firminopolis, Goiás, Brazil.
- To investigate the correlation between AH and key cardiovascular risk factors, including Body Mass Index (BMI), waist circumference (WC), age, and educational level.
Summary:
- A cross-sectional study of 1,168 adults in Firminopolis revealed a 32.7% prevalence of AH.
- Significant correlations were found between AH and increased BMI, elevated WC, and older age.
- Conversely, a higher level of schooling was negatively correlated with AH, suggesting a protective effect.
Impact:
- Findings highlight the substantial public health challenge posed by AH in this Brazilian community.
- Identifies specific risk factors (BMI, WC, age) and a protective factor (education) to inform targeted prevention and management strategies.
- Provides essential data for public health policies aimed at reducing the burden of hypertension in similar populations.
Background:
arterial hypertension (AH) is a health problem that affects a large number of undiagnosed or inadequately treated hypertensive individuals and presents a high rate of treatment nonadherence.
Objective:
to estimate the prevalence of AH and its correlation with some cardiovascular risk factors among the adult population of the town of Firminopolis, state of Goiás, Brazil.
Methods:
descriptive, observational and cross-sectional population-based study of a simple random sample (age > 18 years): standardized questionnaires with blood pressure (BP) measurements (AH criterion: BP > 140 x 90 mmHg), weight, height, Body Mass Index (BMI) and waist circumference (WC). Data were stored (Microsoft Access) and analyzed using Epi-info software.
Results:
we evaluated 1,168 individuals, with a predominance of the female sex - 63.2% and a mean age of 43.2 ± 14.9 years. There was a prevalence of overweight in 33.7% of the individuals and obesity in 16.0% of the individuals. There was a prevalence of altered WC in 51.8% demand of smoking in 23.2%. A sedentary life style at work and leisure activities was present in 67.6% and 64.8% of the individuals, respectively, with a higher proportion seen among the women. Alcohol consumption was observed in 33.3% of the sample. The prevalence of AH was 32.7%, higher among the men (35.8%) than among the women (30.9%). A positive correlation with AH was identified with BMI, WC and age range. A negative correlation was observed between AH and level of schooling, with 18.2% of hypertensive individuals with 9 or more years of schooling.
Conclusion:
a high prevalence of AH, overweight and WC alteration was identified. The female sex represented a protective factor for the risk of AH. A positive correlation was found between AH and BMI, WC and age range; a negative correlation was identified between AH and level of schooling.
