Insights
Prehypertension affects 33.8% of the Veracruz population, particularly males over 40 with basic schooling and comorbidities like diabetes. This highlights significant cardiovascular disease risk factors in the region.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Context:
- Prehypertension, defined by JNC-7 guidelines (systolic 120-139 mmHg, diastolic 80-89 mmHg), is a precursor to cardiovascular disease.
- Identifying prehypertension prevalence and associated factors is crucial for targeted public health interventions.
Purpose:
- To determine the prevalence of prehypertension in a representative sample from Veracruz, Mexico.
- To investigate the correlation between prehypertension and sociodemographic factors, lifestyle, and comorbidities.
Summary:
- A cross-sectional survey revealed a 33.8% prevalence of prehypertension.
- Key risk factors identified include male gender (OR 1.48), age over 40 (OR 1.9), basic schooling (OR 1.73), hyperglycemia (OR 3.0), overweight (OR 1.41), and other comorbidities (OR 1.61).
Impact:
- The findings underscore a high burden of prehypertension in the studied population.
- This research provides essential data for developing preventive strategies against cardiovascular disease in Veracruz, Mexico.
Background:
prehypertension is the category established in JNC-7, which designates the individuals that present diastolic blood pressure of 80-89 mm Hg and systolic blood pressure of 120-139 mm Hg, and it is associated to high rates of cardiovascular disease. The purpose of the study was to identify prevalence rates and their correlation with sociodemographic factors and comorbidity in a sample of a population of Veracruz, Mexico.
Methods:
a cross-sectional and representative survey was chosen by means of probability sampling. Sociodemographic factors, lifestyle and anthropometric characteristics were assessed. Odds ratios and 95 % confidence intervals were obtained.
Results:
the prehypertension prevalence found was 33.8 %, with an average age of 40.9 ± 14.2 years in prehypertensive subjects, and 50.6 ± 12.7 in hypertension subjects (p < 0.05). In relation with prehypertension, males presented a 1.48 (1.18-1.86) OR. Also, those who had more than 40 years had an OR of 1.9 (1.51-2.38); the ones with basic schooling, an OR of 1.73 (1.38-2.17); subjects with hyperglycemia, OR 3.0 (1.5-3.75); with overweight, OR 1.41 (1.01-1.68); and those with other comorbidities an OR of 1.61 (1.09-2.36).
Conclusions:
a high prevalence of prehypertension was found in the sample, and it was associated to male gender subjects, aged above 40 years, with basic schooling and relevant comorbidities, such as diabetes and cardiovascular disease.
