Prevalence and associated factors for awareness of hypertension in India: Findings from national survey-4

Background: Despite the fact that hypertension is increasing, merely 50% are aware of the disease. Being aware of hypertension is important to control it. Aim: The study's objective was to estimate the level of hypertension awareness in India and explore its associated sociodemographic factors. Materials and Methods: The data collected in National Family Health Survey 4 (2015-2016) among men aged 15-54 years and women aged 15-49 years were analyzed. Taking awareness of hypertension as an outcome variable, descriptive analysis, and multivariable logistic regression model were performed, by gender. Results: Of 1,41,215 hypertensive individuals analyzed, 34.7% of men and 53.6% of women were aware of being hypertensive. The control among those aware was 67.1% in men and 74.6% in women. The awareness varied among states ranging from 29.6% in Chhattisgarh to 75.6% in Tamil Nadu. The multivariable logistic regression model explained the awareness of hypertension in males increased with age (odds ratios [OR]: 0.226 for 95% confidence interval [CI]: 0.139-0.366 for 25-29 years of age increased to 0.599 for 95% CI: 0.48-0.74 for 40-44 years of age), education (OR of 0.66 for 95% CI: 0.51-0.85 for primary increased to 0.69 for 95% CI: 0.54-0.89 for secondary school level), and wealth status (OR of 0.407 for 95% CI: 0.309-0.535 for poor wealth quintile increased to 1.030 for 95% CI: 0.863-1.230 for the richest wealth quintile). For women, the awareness increased with age (OR of 0.306 for 95% CI: 0.119- 0.791 for the age of 20-24 years increased to 0.736 for 95% CI: 0.570-0.951 for the age of 45-49 years) and wealth status (OR of 0.28 for 95% CI: 0.18-0.44 for poor wealth quintile increased to 1.262 for 95% CI: 0.859-1.855 for the richest wealth quintile). Conclusion: Improving access to hypertension screening and awareness especially among men, with lower wealth and younger age is needed.
