Frailty and Sarcopenia — Muscle Loss in Older Adults Nigeria

Q: Is getting weaker just part of ageing?

Significant muscle loss is not inevitable. While some loss occurs with ageing, sarcopenia is a pathological acceleration of this process — driven by inactivity, poor nutrition, and disease. People who remain active and eat adequate protein throughout their lives maintain much more muscle mass into their 80s than those who don't.

Q: What is the best food to build muscle in elderly Nigerians?

Eggs are among the most complete protein sources available in Nigeria — 2 eggs daily provides significant muscle-building amino acids. Fish (fresh, dried, smoked) is excellent. Beans (moi moi, akara, gbegiri) provide plant protein. Groundnuts and groundnut soup provide protein and healthy fats. The key is consistency — protein at every meal, not just dinner.

Q: Can an 80-year-old improve their muscle strength with exercise?

Yes — studies consistently show that even people in their 80s and 90s respond to resistance training. A 12-week programme of twice-weekly resistance exercise in nursing home residents with a mean age of 87 increased muscle strength by 113% in one landmark study. The response is slower than in younger people, but it is real and clinically meaningful.

Q: What is the difference between frailty and disability?

Frailty is a state of increased vulnerability — the person is functional but has reduced reserve. They may manage independently until a stressor (minor illness, medication change, hospital admission) tips them into disability. Disability is the actual impairment of function. Frailty is a warning state where intervention can prevent disability. Identifying frailty before it becomes disability is the goal.

Understanding why older Nigerians lose strength — and what to do about it

Sarcopenia is the progressive, generalised loss of skeletal muscle mass and strength that occurs with ageing — beginning in the fourth decade and accelerating significantly after 60. Frailty is a broader clinical syndrome characterised by decreased physiological reserve, making older adults highly vulnerable to adverse outcomes (hospitalisation, disability, death) from even minor stressors like a minor infection, a fall, or a surgical procedure. Both are underdiagnosed in Nigeria, where age-related weakness is normalised as 'old age'. With appropriate nutrition and exercise, both are preventable and — in early stages — reversible.

Signs and Symptoms

✓ Sarcopenia: generalised weakness, reduced grip strength, difficulty rising from a chair without using arms, slow walking pace, muscle wasting (thin arms and legs despite a larger abdomen)

✓ Frailty (Fried criteria — 3 or more = frail): unintentional weight loss > 4.5kg in past year, exhaustion (self-reported), weakness (grip strength below threshold), slow walking speed, low physical activity

✓ Consequences: falls, fractures, poor recovery from illness/surgery, hospitalisation, loss of independence, institutionalisation, death

✓ Pre-frailty (1–2 Fried criteria): window of opportunity for prevention before full frailty develops

Risk Factors

Advanced age (> 75)
Malnutrition — especially low protein intake; poverty-related dietary inadequacy in Nigerian elderly
Physical inactivity — sedentary lifestyle after retirement
Chronic diseases: diabetes (accelerates sarcopenia), heart failure, COPD, CKD, cancer
Malabsorption: vitamin D and B12 deficiency, common in elderly Nigerians
Polypharmacy: steroids, statins (high dose), diuretics all contribute to muscle loss
Depression and social isolation: reduce appetite, activity, and motivation
Hospitalisation: one week of bed rest causes 2% muscle mass loss — recovery takes months in the elderly

When to Seek Help

Unintentional weight loss > 5% in 3 months in an elderly personInvestigate underlying cause: cancer, depression, dysphagia, malabsorption, diabetes — and assess nutritional status

Falls with no clear causeSarcopenia-related weakness and balance impairment — physiotherapy and nutrition assessment

Slow recovery from illness or surgeryPre-frailty or frailty assessment — targeted prehabilitation before planned surgery

Difficulty with daily activities previously managed independentlyFunctional decline — geriatric assessment to identify reversible causes

Before planned major surgery in someone over 70Prehabilitation programme (exercise + nutrition + optimising medical conditions) significantly improves post-surgical outcomes

Tests & Diagnosis

🧪 Grip strength (dynamometer)

Simple, reproducible measure of muscle strength — weak grip (< 27kg men, < 16kg women) is a strong predictor of adverse outcomes. Available with a handheld dynamometer

🧪 SARC-F questionnaire

5 questions on strength, assistance walking, rising from a chair, climbing stairs, falls — screens for sarcopenia without equipment

🧪 Body composition (DEXA or bioimpedance)

Measures muscle mass directly — DEXA available at some Nigerian hospitals. Bioimpedance analysis (body fat scales) increasingly available

🧪 Albumin and prealbumin

Markers of nutritional status and protein synthesis — low albumin indicates malnutrition

🧪 Vitamin D level

Deficiency worsens muscle weakness — very common in Nigerian elderly despite the sun (sun avoidance, dark skin, limited dietary intake)

🧪 Full blood count, thyroid, B12, glucose

Screen for reversible causes of fatigue and weakness

Treatment Options

Resistance exercise — the cornerstone

Progressive resistance training (weights, resistance bands, bodyweight exercises) 2–3 times per week. Even chair-based seated exercises for those with limited mobility. A physiotherapist can design an appropriate programme. Exercise is the most effective treatment for sarcopenia

Protein supplementation and diet

Target 1.2–1.5g protein per kg body weight daily (more than younger adults need). Nigerian protein sources: eggs, fish, beans, chicken, groundnuts, soy. High-quality protein at each meal — not just one large meal. Protein supplements (whey, plant-based) if dietary intake insufficient

Vitamin D supplementation

800–2000 IU daily (particularly important in the dry season when sun exposure is limited or elderly person is mostly indoors). Improves both muscle strength and fall risk

Treat underlying conditions

Diabetes control, optimise heart failure and COPD management, treat depression, review and reduce muscle-wasting medications

Nutritional support

Oral nutritional supplements (Ensure, Complan, local equivalents) for those with malnutrition and inability to meet protein needs from regular diet

Comprehensive geriatric assessment (CGA)

Multidisciplinary assessment covering medical, functional, cognitive, psychological, and social dimensions — available at some Nigerian teaching hospital geriatric clinics
