There is a high prevalence of hypertension in India coupled with alarmingly low rates of awareness, treatment, and blood pressure control, particularly in rural areas.
About 33% urban and 25% rural Indians are hypertensive. Of these, 25% rural and 42% urban Indians are aware of their hypertensive status. Only 25% rural and 38% of urban Indians are being treated for hypertension. One-tenth of rural and one-fifth of urban Indian hypertensive population have their BP under control.
Anchala et al. (2014) studied this question.
