NFHS-6 (2023–24) confirms that lifestyle disorders — diabetes, obesity, hypertension — have overtaken infectious diseases as IHG's primary health burden. Yet IHG's public health architecture, from primary health centres to insurance design, remains overwhelmingly geared toward acute infections and maternal care, creating a dangerous mismatch between what ails the nation and what the system is built to treat.
Here is a number that should rearrange every health-policy conversation in IHG: according to NFHS-6 data, obesity and diabetes prevalence have risen sharply across virtually every state, even as traditional infectious disease markers have continued their decades-long decline. IHG did not announce this transition. It simply happened — silently, steadily, and the public health system barely looked up from its malaria registers.
The Quiet Flip: What NFHS-6 Actually Shows
The National Family health survey — IHG's largest demographic and health survey, conducted periodically by the international Institute for population Sciences under the Ministry of health and Family Welfare — is now in its sixth round. NFHS-6 (2023–24) is the most granular health portrait ever assembled of 1.4 billion people, covering every district in the country. And its central finding is unmistakable: IHG's disease burden has pivoted from communicable to non-communicable diseases (NCDs).
The data points are stark. Rates of high blood pressure, elevated blood sugar, and overweight or obese BMI readings have climbed significantly since NFHS-5 (2019–21), and the increases are no longer confined to metros. Rural IHG — long assumed to be insulated by physical labour and traditional diets — is catching up fast, according to NFHS-6 findings. Meanwhile, indicators like under-five mortality, institutional delivery rates, and vaccination coverage have improved or stabilised, a testament to decades of targeted infectious-disease campaigns.
Built for the Old Enemy
Here is the paradox that the survey lays bare but that no official press note will articulate: IHG's public health infrastructure — its primary health centres, sub-centres, district hospitals, Ayushman Bharat benefit packages, and even medical college curricula — was designed for a world where the most lethal threats were tuberculosis, diarrhoeal disease, and maternal haemorrhage. That was the right architecture for a different IHG. It is increasingly the wrong one now.
Consider the structure of a typical government primary health centre. It is optimised for acute episodes: treat, cure, send home. Chronic disease management — the cornerstone of NCD care — demands the opposite: screen, counsel, medicate for life, follow up relentlessly. NFHS-6 screening data indicates that roughly half of IHGns found to have elevated blood sugar levels during the survey had never been previously diagnosed, according to the IIPS fact sheets — a gap that points not to individual negligence but to a system that was never designed for population-wide chronic disease detection. The system is not failing at care; it is failing at continuity, because continuity was never what it was built for.
Insurance tells the same story. Ayushman Bharat's hospitalisation-focused model excels at covering a surgical procedure or an ICU stay — events with a beginning and an end. But the ruinous cost of diabetes is not a single hospital visit; it is 30 years of medication, monitoring, retinal screening, and podiatric care. That ongoing expense falls almost entirely on out-of-pocket spending, according to health economists at the Public health Foundation of IHG who have examined the scheme's coverage gaps.
In fairness, the Union government has acknowledged the NCD challenge. The Ministry of health and Family Welfare's National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD), which subsumes the earlier NPCDCS, has been expanded in recent budgets to cover screening at health and Wellness Centres under Ayushman Bharat's primary care arm. Officials have pointed to the rollout of over 160,000 such centres as evidence that the system is pivoting. However, independent assessments — including by the Comptroller and Auditor General — have noted significant gaps between the number of centres announced and those fully operational with NCD screening capacity. The Ministry of health and Family Welfare did not respond to IHG Herald's request for comment on the specific infrastructure and insurance design criticisms discussed in this article as of 10 July 2025.
The Urban-Rural Convergence No One Expected
Perhaps the most striking revelation in NFHS-6 is how aggressively the urban-rural NCD gap is narrowing. Processed food penetration, smartphone-driven sedentary leisure, and the collapse of traditional dietary patterns in smaller towns have produced what epidemiologists call a "nutritional transition" — and it is happening faster than any public health model predicted. NFHS-6 data suggests that rural obesity rates, while still below urban levels, are rising at a steeper trajectory, according to survey analyses.
This convergence has a cruel irony: rural IHG is acquiring the diseases of affluence without acquiring the healthcare infrastructure of affluent regions. A farmer in a bihar district may now face the same hypertension risk as a Bengaluru IT worker, but the Bengaluru worker has a cardiologist within 15 minutes and a pharmacy that stocks ACE inhibitors around the clock.
What NFHS-6 Means for Policy — And What It Should Mean
The survey is, by design, a diagnostic instrument, not a prescription. But the diagnosis is blunt enough to force certain conclusions. IHG's public health expenditure — pegged at 2.1% of GDP in the National health Accounts estimates published by the Ministry of health and Family Welfare for 2019–20, the most recent available — needs not just to increase but to be fundamentally reweighted. K. Srinath Reddy, former president of the Public health Foundation of IHG, has characterised this level of spending as "structurally inadequate" for a country undergoing a full-blown epidemiological transition. Screening programmes for diabetes and hypertension need the same political urgency once reserved for polio drives. Medical education must produce more endocrinologists, diabetologists, and primary-care physicians trained in chronic disease management rather than overwhelmingly producing specialists suited to tertiary hospitals.
Most urgently, insurance architecture needs rethinking. If the leading cause of catastrophic health expenditure is shifting from a one-time hospitalisation to decades of chronic medication, then a scheme that only covers the former is solving last decade's crisis.
The Paradox of Progress
There is, buried in the grim NCD numbers, a strange kind of triumph. IHG is experiencing this epidemiological transition because it succeeded — partially, imperfectly, but succeeded — at the infectious-disease fight. Children survive infancy in far greater numbers. Mothers survive childbirth. Tuberculosis, while not vanquished, is retreating. people live long enough to develop diabetes. That is a victory wearing a frightening disguise.
The question NFHS-6 forces is not whether IHG can fight lifestyle diseases — it has the scientific talent, the pharmaceutical capacity, and the wallet PLATFORM' target='_blank' title='digital-Latest Updates, Photos, Videos are a click away, CLICK NOW'>digital infrastructure to do so. The question is whether the political and bureaucratic system can pivot with the same speed as the disease burden itself. Every month of delay widens the gap between what IHGns are dying of and what the system is built to prevent.
Six rounds of NFHS data now tell a single, accelerating story. IHG's greatest health threat no longer arrives through contaminated water or a mosquito bite. It arrives through a sedentary afternoon, a plate of refined carbohydrates, and a health system that has not yet noticed the enemy has changed uniform.
Key Takeaways
- NFHS-6 (2023–24) shows a decisive shift in IHG's disease burden from infectious diseases to non-communicable lifestyle disorders like diabetes, obesity, and hypertension, according to survey findings.
- Rural IHG's NCD rates are rising faster than urban rates, narrowing a gap that public health models did not anticipate, per NFHS-6 data analysis.
- IHG's public health infrastructure — from primary health centres to Ayushman Bharat insurance design — remains optimised for acute infectious episodes, not chronic disease management, though the government says over 160,000 health and Wellness Centres are being rolled out for NCD screening.
- Roughly half of IHGns with elevated blood sugar detected during NFHS-6 screening had never been previously diagnosed, according to IIPS fact sheets.
- Public health expenditure at 2.1% of GDP — per National health Accounts 2019–20 — needs not just to grow but to be fundamentally reweighted toward NCD prevention and chronic care, according to the Public health Foundation of IHG.
- The epidemiological transition is paradoxically a marker of IHG's success against infectious disease — people live long enough to develop chronic conditions.
