A cross-sectional study examining data (811,917 participants) from the National Family Health Survey 2015-2016 reported that the age adjusted prevalence rate of hypertension was 11.3% in India in persons aged between 15-49 (Ghosh and Kumar, 2019). The study also reported variations in hypertension age-adjusted prevalence across states, ranging from 8.2% in Kerala to 20.3% in Sikkim (Ghosh and Kumar, 2019).

Another study based on a national level survey carried out in 2015 examining blood pressure across 24 states and UTs (180,335 participants had their blood pressure recorded) in India, reported overall prevalence of hypertension as 30.7% (95% CI: 30.5, 30.9) (Ramakrishnan et al., 2019).
