Hypothesis
The study aims to estimate the prevalence of hypertension and its association with various risk factors among the Nicobarese tribe.
Conclusion
The study found a high prevalence of hypertension (50.5%) among the Nicobarese population, linked to factors like age, education, and obesity.
Supporting Evidence
- The prevalence of hypertension was found to be 50.5% among the Nicobarese population.
- Significant associations were found between hypertension and age, education, alcohol consumption, and obesity.
- Only 12% of those with hypertension were aware of their condition.
Takeaway
This study shows that many people in the Nicobarese tribe have high blood pressure, which can be caused by things like getting older and not having enough education.
