Prevalence and predictors of prehypertension and hypertension in adult population of rural Southern India-An epidemiological study.

INTRODUCTION

Hypertension is considered as one of the major health problem worldwide and the most important risk factor for non-communicable diseases.

AIMS

To estimate the prevalence and the risk factors of prehypertension and hypertension.

METHODS AND MATERIAL

A community-based cross-sectional study was conducted among adult population of rural area of Chittoor District. WHO STEPS was applied for data collection from 1,742 study participants aged 18 years and above. Chi-square test, Fisher exact, and ANOVA test applied to find out the intragroup and intergroup variable association with raised blood pressure.

RESULTS

The overall prevalence of hypertension and prehypertension in our study was 21.5% [95% CI: (19.6-23.5)] and 42.8% [95% CI: (39.5-46.3)], respectively. Males had higher prevalence when compared to females. The mean systolic and diastolic blood pressure was 118.7 ± 17.6 mmHg and 77.1 ± 9.7 mmHg, respectively. The odds of being hypertensive was higher among older age group (OR: 3.83), male study participants (OR: 1.83), either widowed or separated (OR: 2.03), unemployed (OR: 1.51), and those who belonged to upper socioeconomic status (OR: 2.01). Those who were overweight (OR: 3.15), obese (OR: 2.55) and having central obesity (OR: 1.74), and also tobacco smokers (OR: 1.53) were having higher odds of hypertension. Significant association was found between hypertension and age, gender, marital status, body mass index, abdominal obesity, tobacco smoking, and physical inactivity.

CONCLUSION

The prevalence of prehypertension and hypertension in this study was found to be high in rural area of Andhra Pradesh. There is a need to develop a community-based program, which would aim at minimizing the risk factors of hypertension.
