Health Problems of the Aged

(Community Medicine - 10 Mark Answer)

(Park's Textbook of Preventive and Social Medicine)

Introduction

Ageing is a natural, inevitable biological process. Gerontology is the study of physical and psychological changes incident to old age, while geriatrics refers to the clinical care of the aged. The global elderly population (65+ years) was ~694 million in 2019, with 540 million in developing countries. In India, 9.3% of the total population was above 65 years in 2019. This demographic shift brings major social, economic, and healthcare challenges.

Classification of Health Problems of the Aged

1. Problems Due to the Ageing Process (Senescence)

"Senescence" refers to the deterioration in biological efficiency that accompanies ageing. Disabilities considered incident to the ageing process include:

Disability	Description
Senile cataract	Lens opacification causing visual loss
Glaucoma	Raised intraocular pressure
Nerve deafness	Sensorineural hearing loss (presbycusis)
Osteoporosis	Bone mineral loss, increased fracture risk
Emphysema	Loss of alveolar elasticity
Failure of special senses	Decline in vision, hearing, taste, smell
Mental changes	Impaired memory, rigidity of outlook

2. Problems Associated with Long-Term (Chronic) Illness

Chronic diseases are more frequent among older people. These include:

(a) Degenerative Diseases of Heart and Blood Vessels

Of particular importance after age 40
Lipoid material deposited in artery walls → calcium deposition → atherosclerosis → reduced blood supply, thrombus formation, hypertension
Cardiovascular diseases are the leading cause of death in developed countries
Risk factors: diet, heredity, overweight, emotional strain

(b) Cancer

Risk rises rapidly after age 40
Cancer of the prostate is common after age 65
A leading cause of death in developed countries

(c) Accidents

Bones become fragile due to decalcification
More common in the home than outside
Fracture of the neck of femur is a very common geriatric problem

(d) Diabetes Mellitus

Long-term illness due to faulty carbohydrate metabolism
About 75% of diabetics are over 50 years of age
A leading cause of death as the population grows older

(e) Diseases of the Locomotor System

Wide range of articular and non-articular disorders: fibrositis, myositis, neuritis, gout, rheumatoid arthritis, osteoarthritis, spondylitis of the spine
These cause more discomfort and disability than any other chronic disease in the elderly

(f) Respiratory Illnesses

Chronic bronchitis, asthma, emphysema are of major importance in upper decades of life

(g) Genitourinary Problems

Enlargement of the prostate, dysuria, nocturia, frequency and urgency of micturition are common complaints in elderly men

3. Psychological Problems

(1) Mental Changes

Impaired memory, rigidity of outlook, dislike of change
Reduced income leads to fall in living standards, with mental and social consequences

(2) Sexual Adjustment

Between 40 and 50, cessation of reproduction in women and diminution of sexual activity in men
Physical and emotional disturbances, irritability, jealousy, and despondency are frequent

(3) Emotional Disorders

Result from social maladjustment; failure to adapt to ageing can lead to bitterness, inner withdrawal, depression, weariness of life, and even suicide

4. Social Problems

Problem	Details
Economic dependence	Loss of employment/income post-retirement
Isolation and loneliness	Loss of spouse, friends, social contacts
Inadequate housing	Inability to maintain independent living
Nutritional deficiencies	Poor intake, malabsorption, poverty
Polypharmacy	Multiple drugs, risk of adverse effects and drug interactions

Preventive Health Care in the Elderly (Park's Table 31)

Level	Examples
Primary Prevention	Cessation of smoking, alcohol, obesity control, physical activity, immunization (influenza, pneumovax, tetanus), injury prevention, osteoporosis prevention
Secondary Prevention	Screening for hypertension, diabetes, cancers (colorectal, breast, cervical, prostatic), depression, fall risk, TB (high-risk), urinary incontinence
Tertiary Prevention	Rehabilitation of physical, cognitive and functional deficits; caretaker support; prevention of loss of autonomy

Lifestyle and Healthy Ageing

Key lifestyle factors for healthy ageing include:

Regular physical activity - maintains muscle strength, balance, cardiovascular fitness
Balanced nutrition - adequate protein, calcium, vitamins D and B12
Social engagement - prevents isolation and depression
Mental stimulation - reading, hobbies, cognitive exercises
Regular health check-ups - for early detection and management of chronic diseases
Avoidance of tobacco and alcohol

National Programme for Health Care of the Elderly (NPHCE)

India has a dedicated national programme to provide dedicated health care services to the elderly population, focusing on preventive, promotive, curative and rehabilitative services at all levels of health care - from sub-centre to district hospital level.

Summary

The health problems of the aged can be broadly grouped as:

Ageing process problems - senile cataract, osteoporosis, deafness, emphysema
Chronic disease problems - cardiovascular disease, cancer, diabetes, arthritis, COPD
Psychological problems - dementia, depression, emotional disorders
Social problems - isolation, poverty, inadequate housing, polypharmacy

A comprehensive approach involving primary, secondary, and tertiary prevention, combined with social welfare measures and community support, is essential for the health care of the elderly.
