Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
The article by Chen et al. brought the focus back on to Hypertension, an important contributor of many Non Communicable Diseases (NCDs).  Whether screening reduces mortality or not is a different question but it definitely increases awareness and encourages people to seek medical help.
In India, among the risk factors implicated in Disability Adjusted Life Years (DALY), hypertension is the fourth most common one.  Among the age group 15-49 years, 8.8% of women and 13.4% of men were found to be hypertensive.  A recently launched project aims at identifying factors related to compliance with anti-hypertensive medication and improving it for achieving better control of hypertension.  Population Based Screening has been commenced for all people above 30 years of age for hypertension and four common NCDs. Along with community based risk assessment, there are components like referral and follow up. In a country with two-third mortality due to NCDs, it is expected to boost early diagnosis of hypertension and prevent complications in the long run. [2,5]
