Key result
Prehypertension affects ~37% of South Indian adults, linked to age, overweight, and excess salt intake.
Why the study?
The burden of prehypertension prevalent in the community is not much explored, and early detection is important to control progression to hypertension and related diseases.
Population

Comparison
Adults with and without prehypertension based on socio-behavioral and dietary factors
Design
Community-based cross-sectional study using WHO STEPwise survey tool

South Indian prevalence data support targeted screening; leaves open causal roles of socio-behavioral factors in prehypertension.
Cross-Sectional (n=2,213)
Over one-third of undiagnosed adults in urban South India have prehypertension, highlighting the need for community-based screening and lifestyle interventions targeting modifiable risk factors like BMI and salt intake.
Kar et al. (2020) conducted a cross-sectional in Prehypertension (n=2,213). Socio-behavioral and dietary factors vs. Absence of risk factors was evaluated on Prevalence of prehypertension (95% CI 34.6-38.6). Among 2,213 adults in South India, the prevalence of prehypertension was 36.6% (95% CI 34.6-38.6%), and was associated with age 45-54 years, BMI >23 kg/m2, and salt intake >6 g/day.
