Summary
Hypertension prevalence in India significantly varies based on differing guidelines and single blood pressure readings. Adopting universal, evidence-based diagnostic methods is crucial for accurate clinical practice.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Hypertension prevalence estimation is critical for public health.
- Variability in diagnostic guidelines impacts population health metrics.
- Accurate hypertension diagnosis is essential for effective management.
Purpose of the Study:
- To assess the impact of diverse hypertension management guidelines on prevalence in India.
- To evaluate the effect of single blood pressure readings on hypertension diagnosis.
- To compare prevalence estimates across different guidelines and diagnostic criteria.
Main Methods:
- Secondary analysis of the Fourth National Family Health Survey (2015-2016).
- Calculation of raised blood pressure prevalence across six guidelines and three age groups.
- Assessment of prevalence changes based on single versus multiple blood pressure measurements.
Main Results:
- Government of India guidelines showed lowest prevalence (7.5%), while ACC/AHA guidelines showed highest (40.1%).
- Using single readings could misdiagnose 56 million individuals under Indian guidelines.
- Prevalence varied up to threefold between ACC/AHA and Indian guidelines.
Conclusions:
- Different hypertension guidelines yield significantly different prevalence rates in India.
- Reliance on single blood pressure readings can lead to widespread misdiagnosis.
- Standardized, evidence-based diagnostic approaches are necessary for optimal hypertension care.
