Ageing and Geriatric Health
On this page
Direct answer
At the 2011 Census, India counted 104 million people aged sixty and above — 8.6 per cent of the population — and that share has since crossed 10 per cent, with UNFPA's India Ageing Report projecting about 20 per cent elderly by 2050; the "ageing of the aged", the fastest growth in the over-eighties, compounds the challenge. Geriatric medicine meets this shift with its giants — falls, immobility, instability, incontinence, intellectual impairment and iatrogenesis (polypharmacy above all) — while public health answers through the National Programme for Health Care of the Elderly (launched 2010-11), the Maintenance and Welfare of Parents and Senior Citizens Act 2007, and the WHO's Decade of Healthy Ageing 2021-2030. Kerala and Tamil Nadu lead the demographic transition, making geriatric services a southern reality today and a national one within a generation.
What you must remember
- Demography: 60-plus threshold for developing countries (UN convention for developed ones is 65); 104 million (8.6 per cent) in 2011, about 10 per cent now, roughly 20 per cent projected by 2050; women outlive men, so a majority of the very old are widows.
- NPHCE (2010-11): dedicated geriatric OPDs and day-care centres at district level, rehabilitation services, regional geriatric centres of excellence, and training of health workers in elder-friendly care.
- Legal and policy shield: Maintenance and Welfare of Parents and Senior Citizens Act 2007 (amended 2019) makes maintenance enforceable and penalises abandonment; National Policy on Older Persons 1999; Rashtriya Vayoshri Yojana (2017) supplies physical aids free to poor elders; Elder Line 14567.
- Geriatric giants: falls (the second leading cause of unintentional injury death in elders), immobility, instability, incontinence, intellectual impairment (delirium versus dementia), and iatrogenesis — polypharmacy checked against lists of potentially inappropriate drugs such as the Beers criteria.
- Normal ageing versus disease: presbyopia and presbycusis, sarcopenia and slowed gait are ageing; confusion is not normal ageing — hunt delirium, drugs, depression or dementia.
- Vulnerabilities: loneliness after child migration ("empty nest"), elder abuse (frequently by caregivers, often unreported), financial insecurity, malnutrition and neglect of chronic disease.
- WHO framing: Decade of Healthy Ageing 2021-2030 — age-friendly environments, combating ageism, integrated care and long-term care.
- Prevention pays: vision correction, home hazard removal, balance and strength exercise, vitamin D assessment, medication review and vaccination (influenza, pneumococcal) prevent the classic downward spiral of fall-fracture-immobility.
One fall, and what a good system does about it
A 78-year-old hypertensive on four drugs trips on an unlit stair at home and fractures her femur. The acute sector fixes the neck of femur; the community health centre's job starts before and after. Before: cataract surgery (poor vision is a leading fall risk), review of her antihypertensives (postural hypotension), stair lighting and rails, and strength exercises — all cheaper than the surgery. After: physiotherapy through the NPHCE day-care centre, home visits by the ASHA to check medication and nutrition, and a social audit for neglect, because a second fall is predictable if the environment does not change. India's model remains family-based care; the state's role is to support that family (pension top-ups, respite, aids) and to fill the gap when the family fails — which is exactly what the Maintenance Act's tribunal exists to enforce.
How the exam frames ageing
The high-frequency facts are programme names and years — NPHCE 2010-11, the 2007 Maintenance Act, the 2021-2030 Decade of Healthy Ageing — asked as direct matches. The second pattern is the definition question: geriatric giants (or "great giants" as older MCQ books print), where the wrong option list inserts a disease like stroke instead of a syndrome like instability. Third, distinguish the forgetfulness of normal ageing from mild cognitive impairment from dementia, and know the timed functional assessments — the Katz activities-of-daily-living and instrumental ADL scales appear in options more often than in clinics. Finally, the demographic one-liner: developing countries use 60 as the elderly threshold — choose 65 and you have used the developed-country convention.
Frequently asked questions
What is the National Programme for Health Care of the Elderly?
The NPHCE, launched 2010-11, providing dedicated geriatric outpatient and day-care services, rehabilitation, regional geriatric centres and health-worker training.
Which law protects Indian senior citizens from abandonment?
The Maintenance and Welfare of Parents and Senior Citizens Act 2007, amended 2019, which makes adult children legally liable for maintenance.
What are the geriatric giants?
Falls, immobility, instability, incontinence, intellectual impairment and iatrogenesis — syndromes of multifactorial origin rather than single diseases.
Why is polypharmacy especially hazardous in the elderly?
Reduced renal and hepatic clearance, multiple prescribers and interacting drugs produce adverse events and delirium, driving the iatrogenic giant.
What age defines an elderly person in India?
Sixty years, following the developing-country convention; developed countries and UN agencies often use sixty-five.
