Key result
In an urban adult population in North India, the prevalence of hypertension was 52% (208 of 400 participants), with 139 of those 208 individuals being aware of their diagnosis.

Does the 'rule of halves' apply to hypertension awareness and control in an urban adult population in North India?
The study demonstrates that the 'rule of halves' remains highly relevant for assessing hypertension awareness and control in developing countries, revealing a 52% prevalence with significant under-awareness.
May indicate persistent awareness gaps in high-prevalence urban India; supports rule-of-halves relevance but leaves open need for prospective studies.
Introduction: Approximately half of most common chronic disorders are undetected that half of those detected are not treated, and that half of those treated are not controlled. This is true of hypertension as well: The “rule of halves.” However, the relevance of this is being questioned now.Objective: The aim of the present study was to assess the applicability of the rule of halves in an urban adult population in North India to evaluate its relevance in establishing levels of awareness, thus control of hypertension in general population.Materials and Methods: A cross-sectional community survey was done to include 187 men and 213 women aged >20 years of age in Shimla city, Himachal Pradesh. Hypertension was assessed using standardized recording, structured schedule on diagnosis and antihypertensive drug treatment according to The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure.Results: The data were expressed in percentages, and Chi-square test was used to list the significance of sociodemographic factors. Of the total 400 participates, 208 individuals (52%) had hypertension. The prevalence of self-reported hypertension was 35% (139/400). However, the prevalence of self-reported hypertension (aware) among diagnosed patients of hypertension on examination by investigator was 139/208.Conclusion: The relevance of “rule of halves” in establishing the levels of awareness and control of hypertension is undervalued and cannot be undermined especially in context of developing countries.

Mahajan et al. (2015) conducted a cross-sectional in Hypertension (n=400). Hypertension was evaluated on Prevalence of hypertension. In an urban adult population in North India, the prevalence of hypertension was 52% (208 of 400 participants), with 139 of those 208 individuals being aware of their diagnosis.
