Unveiling the Silent Killer: PGIMER's Landmark Analysis of Hypertension in India

Hypertension, often dubbed the 'silent killer', poses a massive public health challenge in India, affecting an estimated 200 million adults. A groundbreaking study from the Postgraduate Institute of Medical Education and Research (PGIMER) in Chandigarh has brought to light alarming shortcomings in the nation's hypertension management system. Presented at PGIMER's 12th Annual Research Day, the research titled 'Hypertension treatment cascade among men and women of reproductive age group in India' analyzed data from the National Family Health Survey-5 (NFHS-5, 2019–2021), revealing that only about 8% of hypertensives have their blood pressure under control.

This analysis underscores the urgent need for targeted interventions to bridge gaps in screening, diagnosis, treatment adherence, and control, particularly among vulnerable populations. As India grapples with rising non-communicable diseases (NCDs), such insights from premier institutions like PGIMER are pivotal for policymakers and healthcare providers.

The Methodology Behind the PGIMER Findings

Led by Prof. Sonu Goel from PGIMER's School of Public Health, the study leveraged NFHS-5 data—a nationally representative survey covering over 1.26 million individuals across all states and union territories. It focused on adults of reproductive age: men aged 15–54 years and women aged 15–49 years. Hypertension was defined using standard criteria: systolic blood pressure ≥140 mmHg and/or diastolic ≥90 mmHg, or self-reported anti-hypertensive medication use, or prior diagnosis.

The 'treatment cascade' framework tracked progression: proportion screened (ever had BP measured), aware (diagnosed), on treatment (taking prescribed drugs), and controlled (BP <140/90 mmHg while on treatment). Multinomial logistic regression identified socio-demographic, lifestyle, and access factors influencing each stage. This rigorous approach provides a clear picture of systemic bottlenecks.

Shocking Statistics: Prevalence and Cascade Breakdown

The study reported a hypertension prevalence of 18.3% among reproductive-age adults—21.6% in men and 14.8% in women. While 70.5% had been screened, only 34.3% were aware of their condition, 13.7% were on treatment, and a mere 7.8% achieved control. This translates to massive 'leaks': 51.4% drop from screening to awareness, 60% from awareness to treatment, and 43.1% from treatment to control.

• Screened: 70.5% (high due to routine checks, but urban-rural gap exists)
• Aware: 34.3% (men lag behind women)
• Treated: 13.7%
• Controlled: 7.8%—far below global targets

These figures highlight India's deviation from the 'rule of halves' (where half are aware and half of those controlled), emphasizing deeper systemic issues.

Gender and Regional Disparities in Hypertension Management

Women outperformed men at every cascade stage, with higher awareness (likely due to antenatal screening) and treatment adherence. Rural-urban divides persist: urban areas show higher prevalence (due to lifestyle) but better screening; rural gaps in access widen untreated cases.

State variations are stark: Goa (91.1% screened, 26.8% treated), Meghalaya (18.7% controlled), vs. Chhattisgarh (19% aware, 7.8% treated) and Nagaland (3.5% controlled). High-focus states (poorer regions) excel in awareness but lag in treatment/control; non-high-focus states reverse this.

Such disparities demand tailored, region-specific strategies.

Root Causes: Why Do Gaps Persist?

Several factors contribute: low health literacy (especially men, rural poor), lifestyle risks (tobacco 1.2x higher uncontrolled risk, alcohol similar), comorbidities (diabetes doubles gaps), and access barriers (private facilities boost screening but cost hinders treatment). Forgetfulness, side effects, and myths (e.g., 'curable') fuel non-adherence. Economic constraints hit lower wealth quintiles hardest.

• Tobacco/alcohol users: Lower progression across cascade
• Obese/high BMI: Better screening but poor control
• STs/illiterates: Lowest awareness
• Rural/poor: Treatment drop-offs

Addressing these requires multi-level interventions.

India Hypertension Control Initiative (IHCI): Promising Solutions

IHCI, a WHO-ICMR-Resolve collaboration involving PGIMER, scaled protocol-based care to 15 states/89 districts, enrolling 1.2 million hypertensives. By 2022, 44% under-care patients achieved control (52% on two readings)—a leap from baseline ~37%. Simplified drugs, patient cards, team care, and digital tracking drove gains. Primary facilities shone (85% control at HWCs).IHCI BMJ study

Key lessons: Focus on adherence, integration with NCD programs, capacity building. Scaling nationally could hit WHO's 25x25 target (25% BP reduction by 2025).

Stakeholder Perspectives and Expert Insights

Prof. Sonu Goel emphasizes: 'Hypertension's silence demands proactive screening and education.' PGIMER's role in IHCI exemplifies academic impact. Policymakers eye Ayushman Bharat for expansion; experts urge gender-sensitive campaigns, rural outreach, and tobacco control linkage.

Health economists note cost-savings: Controlled hypertension averts strokes (1.5M/year India), heart attacks. Multi-stakeholder forums like PGIMER Research Day foster solutions.

Implications for Public Health and Policy

Uncontrolled hypertension fuels 10.8% CVD deaths in India. Gaps exacerbate inequities, straining Ayushman Bharat Health Accounts (ABHA). Policy shifts: Mandate annual screening >30s, subsidize generics, integrate with diabetes care. Digital tools like IHCI app enhance follow-up.

Higher ed institutions like PGIMER must train more epidemiologists. Link to higher ed jobs in India for public health roles.

Future Outlook: Pathways to Better Control

Optimism from IHCI (48% control in pilots) and tech (telemedicine, AI BP monitors). Target: 50% control by 2030 via NCD policy 2.0. Research priorities: Rural adherence trials, male-focused interventions, climate-lifestyle links.

Call to Action: Bridging the Gaps Together

India's hypertension crisis demands collective effort. Leverage PGIMER's findings for localized plans. Aspiring professionals, pursue higher ed jobs in public health. Policymakers, scale IHCI. Individuals, monitor BP regularly. For career advice, check higher ed career advice.
