Hypertension: The most important non communicable disease risk factor in India

Area of Science:

• Public Health
• Cardiovascular Medicine
• Epidemiology

Background:

• Non-communicable diseases (NCDs) are a major cause of death and disability in India.
• Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity.
• Hypertension is identified as the primary risk factor for CVD in India.

Purpose of the Study:

• To highlight the significant disease burden attributed to hypertension in India.
• To emphasize the urgent need for public health interventions in hypertension awareness, treatment, and control.
• To underscore the role of hypertension control in achieving global NCD reduction targets.

Main Methods:

• Analysis of data from the Registrar General of India, WHO, and the Global Burden of Disease (GBD) Study.
• Review of case-control studies identifying hypertension as a key risk factor for CVD.
• Estimation of deaths and disability-adjusted life years (DALYs) attributed to hypertension.

Main Results:

• Age-adjusted mortality from CVD has increased by 31% in the last 25 years.
• Hypertension caused 1.6 million deaths and 33.9 million DALYs in India in 2015.
• Improved hypertension control could prevent 400,000-500,000 premature deaths annually.

Conclusions:

• Hypertension represents the most significant cause of disease burden in India.
• Intensified public health efforts are crucial for managing hypertension.
• Effective hypertension control is vital for meeting the UN Sustainable Development Goals for NCD reduction.
