Ageing well and frailty:
the role of muscle

Frail and sarcopenic patients are at increased risk of malnutrition and muscle loss, which in turn, can escalate the progression of frailty.1,2 However, frailty can be treated and promoting healthy ageing from middle age onwards could delay its onset as people grow older.3,4

As our population ages, so too does the demand on our healthcare system.5

The focus for NHS organisations is to deliver a proactive population health approach for patients as they age. This is especially important for those most at risk of negative health outcomes such as frailty/pre-frailty and muscular skeletal-conditions, where early identification and intervention can improve strength, reduce falls and hospital admissions, and help people maintain their independence as they get older.6

THE IMPORTANCE OF MUSCLE STRENGTH FOR HEALTHY AGEING

Strategies for healthy aging typically focus on optimising health and minimising chronic disease and physical decline, with the ultimate goal of helping individuals maintain their independence.4 However, a notable consequence of ageing is the involuntary decline of muscle mass, strength and function, sometimes referred to as sarcopenia.7

Sarcopenia is defined as an age-related loss of muscle, but loss of muscle mass/function can be seen as early as the age of 30:7,8

8% decline 8% decline
Upto 50% Upto 50%

Sarcopenia often leads to frailty, a term which typically incorporates a reduction in health, energy levels and cognition, leading to increased susceptibility to further illness and a decline in physical and mental health.1,4

THE BURDEN OF MUSCLE LOSS FOR FRAIL PATIENTS 

Frailty is a common consequence of ageing and is closely related to sarcopenia (age-related muscle loss) due to their shared physical characteristics i.e. lower lean mass and reduced muscular function.9

As adults become less active, and consume less protein and calories due to other chronic diseases, this can lead to fatigue, accelerated sarcopenia and an overall decline in muscle mass.8

Sarcopenia is prevalent in up to 13% of adults aged 60-70 years, increasing to 50% in people aged >80 years.10

Muscle loss
CAUSES OF LOW MUSCLE MASS IN FRAIL PATIENTS

Frail patients are at increased risk of malnutrition, muscle loss and worsening frailty due to:11,12

  • Decreased metabolic rate
  • Decline in immune resilience
  • Reduced antioxidant micronutrients
  • Oxidative stress
CONSEQUENCES OF LOW MUSCLE MASS IN FRAIL PATIENTS
Frail patients Frail patients

In a stressed state, the body requires more amino acids from muscle breakdown, leading to accelerated protein degradation as amino acids are released to deal to increase metabolic rate for fuel. Patients with low muscle mass have difficulty coping with metabolic stress, negatively impacting survival, and recovery.13 

Extended periods of immobilisation, such as during acute hospitalisation, can worsen muscle loss and prolong recovery. If muscle loss persists before the body enters a stressed state, restoring normal function becomes unlikely.13

Sarcopenia and frailty are associated with an increased risk of poor outcomes for patients, particularly as they age:14-16

Higher risk of mortality

Consequences of frailty on patients' quality of life

Sarcopenia and frailty can also have a significant impact on patients’ daily life, their social and their mental health. Patients with sarcopenia often experience a significant physical burden which can result in the inability to perform simple daily tasks, such as standing and walking and often suffer with fatigue, muscle pain and falls.17

Moreover, patients often report that their sedentary lifestyles actually make these issues worse. In addition to the physical limitations that sarcopenia poses, patients have also described the emotional impacts of feeling physically frail such as embarrassment of their physical limitations and feeling isolated due to limiting social interactions.17

MUSCLE LOSS, SARCOPENIA AND FRAILTY CAN BE REVERSED IF IDENTIFIED AND TREATED EARLY

Although frailty and declining physical function are associated with increased age, promoting healthy ageing from middle age onwards could delay the onset of frailty as people grow older.4 There is also evidence that improving nutrition and weight loss can reduce frailty.9

Timely identification of frailty symptoms, such as loss of muscle mass, combined with targeted support, including nutritional intervention, can improve patients’ quality of life, enabling them to live independently for longer.18-20

Frailty can be costly to healthcare services, with social care costs calculated to be over 800% higher for frail people than non-frail people. However, for every 1% of people in England prevented from developing frailty, social care savings of £4.4m per annum could be realised.21,22

THE IMPORTANCE OF MALNUTRITION AND MUSCLE SCREENING/ASSESSMENT AND INTERVENTION

Screening for undernutrition/frailty is critical for early assessment and intervention to maintain functionality and support healthy ageing.23

Muscle screening and assessment are recommended by the European Working Group on Sarcopenia in Older People (EWGSOP2).24 They can be quick, inexpensive and easy to apply in clinical practice.24,25

Screening can easily identify limited strength and performance, a strong predictor of adverse negative health outcomes and can be easily used to increase physical activity and implement nutrition interventions.25,26

THE IMPORTANCE OF MEDICAL NUTRITON FOR PATIENTS WITH FRAILTY

To prevent the decline in muscle strength in older life, early interventions should be made with nutrition and exercise.15

Key Nutrients Can Increase Muscle Strength and Improve Quality of Life

Protein

Adequate protein intake is essential to help minimise declines in strength and function.27 High protein supplements can help reduce complications and improve weight.28

HMB

HMB is a metabolite of leucine, a branched-chain essential amino acid exclusively obtained from dietary sources29

Vitamin D

Vitamin D acts directly on muscle to promote its function through specific vitamin D receptors found on muscle cells.30 It plays an important role in maintaining musculoskeletal health and can help reduce the risk of falls and improve mobility.32,33

§ ACBS indication: as a nutritional supplement for frail elderly people (>65 years of age, with a BMI ≤ 23kg/m2), where clinical assessment and nutritional screening show the individual to be at risk of undernutrition. * As shown in a randomised control trial to investigate the effects of the intervention ONS on malnourished, cardiopulmonary patients (≥65 years) vs placebo. The intervention ONS decreased mortality at 90 days post-discharge, however the study did not observe a significant effect for the primary composite endpoint of non-elective readmission or death. This post-hoc, sub-group analysis from the NOURISH study cohort comprised 214 COPD patients. †Strength was measured by handgrip strength in a post hoc analysis of over 600 malnourished people with heart or lung diseases, age 65 or older. Study product was consumed twice a day for 30 days, as compared to standard of care. ‡‡ In 330 older adults with malnutrition and sarcopenia. Muscle quality was calculated as leg strength expressed relative to the muscle mass. §§ As shown in a randomised control trial to investigate the effects of a specialised ONS on older women (≥65 years) who underwent surgery for hip fracture vs. standard post-operative nutrition. Post-operative nutrition provided 1900 kcal and 76 g protein a day. Muscle function was measured by handgrip strength. Mobilisation status was assessed on post-operative days 15 and 30. ¶ An open-label study of elderly (n=35) patients with recent weight loss (>5% during previous 3 months) showed that 12 weeks supplementation of experimental product twice daily increased dietary intake, biochemical variables, and quality of life compared to baseline. ¶¶ In 65 healthy older female patients who regularly attended a fitness programme. ~ As shown in a randomised controlled trial in which normally nourished patients with non-cystic fibrosis bronchiectasis received pulmonary rehabilitation plus a specialised ONS or pulmonary rehabilitation only for 12 weeks. In the intervention group, mean and maximum handgrip dynamometry, physical functioning domain of QOL-B-V3.0 and other outcomes were significantly increased from baseline at 12 weeks and 24 weeks and fat free mass at 12 weeks. # As shown in a randomised control trial to investigate the effects of the intervention ONS on malnourished, cardiopulmonary patients (≥65 years) vs placebo.

Mobilisation status was assessed on postoperative days 15 and 30. The control group received standard postoperative nutrition (1900 kcal and 76 g protein a day), while the intervention group received 2 servings a day of a high protein ONS with calcium ß-hydroxy-ß·methylbutyrate and additional vitamin D between meals in addition to the standard postoperative nutrition plan. Muscle function was measured by handgrip strength.
