Study Notes
Nutrition in Older Adults
- Older adults experience changes in gastrointestinal (GI) tract function, affecting the absorption of essential vitamins.
- Physiological and biochemical changes due to aging impact nutritional needs.
- Malnutrition significantly impacts older adults' physical and cognitive status, both short- and long-term.
- Social, economic, and medical factors all influence the dietary intake of older adults.
- Sarcopenic obesity is a condition where muscles decrease while body fat increases, posing health risks.
- Interventions are crucial for preventing malnutrition, sarcopenia, osteoporosis, and cognitive decline in older adults.
- Drug-nutrient interactions from prescriptions and over-the-counter medications should be evaluated.
Anorexia of Aging
- Decreased appetite and food intake are major contributing factors to undernutrition in older adults.
- Anorexia of aging significantly predicts morbidity and mortality.
- Age-related changes in appetite and satiety signals don't automatically mean it's an unavoidable consequence of aging.
Diminished Hunger and Altered Satiety Control
- Ghrelin levels decrease during fasting, a key hunger hormone.
- Key satiety hormones (cholecystokinin, GLP-1, PYY) increase in older adults.
- Other satiety hormones (leptin and insulin) experience changes in older adults.
Age-Related Gastrointestinal (GI) Changes
- The GI tract is less affected by aging compared to other organ systems.
- Digestive tract functions, like motility, may slow with age.
- Digestive issues like disorders also increase with age.
- Reduced saliva, decreased jaw strength, and altered taste perception can lead to chewing and swallowing difficulties.
- Changes in esophageal contractions and tension in the upper esophageal sphincter occur with age.
- Stomach elasticity decreases, and gastric emptying can increase and be affected by diet type.
- Lactase levels decrease, leading to dairy intolerance.
- Microbial growth in the small intestine leads to nutrient absorption issues (like iron, calcium, and B12).
- Transit time through the large intestine prolongs. Prevalence of constipation increases with age.
- Rectal enlargement and reduced contraction intensity may also be issues.
Other Factors: Taste and Smell
- Taste and smell receptors undergo age-related decline.
- Zinc deficiency may impair taste.
- Issues like dysphagia and reduced ability to chew food impacts taste sensation.
Other Factors: Depression
- Loneliness and lack of caregivers may prevent proper nutrition.
- Difficulty getting or preparing foods can lead to inadequate nutrition.
- Medical problems like endocrine disorders can also lead to appetite loss and depression.
- Challenges with existing dentition impact oral health and the ability to chew effectively.
- Financial struggles limit access to ample, nutritious foods.
Other Factors: Drugs
- Certain medications like amiodarone, SSRIs, H2 receptor antagonists, and antibiotics can impact nutrient absorption, or cause deficiencies.
- These medications should be reviewed and possibly adjusted or substituted for the safety and health of an older adult.
Malnutrition and Cognitive Status
- Micronutrient deficiencies can have a notable effect on older adult cognitive function.
- Deficiencies in B1, B2, B6, B12, C, and folate vitamins can cause cognitive impairment.
Sarcopenia
- A progressive degenerative disorder impacting older adults, characterized by involuntary muscle loss, weakness, and frailty, affecting over 40% of those 70+
- Anorexia of aging, protein imbalances, and oxidative stress contribute to sarcopenia.
- Increased adipose tissue often accompanies sarcopenia.
Changes in Body Fat
- Body fat increases with age, while fat-free mass (muscle) decreases, partly due to decreased physical activity, reduced growth hormone, and decreased sex hormones.
- Fat distribution shifts to intra-hepatic and intra-abdominal areas in older adults, increasing health risks.
- Insulin resistance is also connected and risk factors for ischemic heart disease, stroke, and diabetes.
Health Consequences of Sarcopenic Obesity
- Sarcopenic obesity is associated with increased disability, higher hospitalization risks, and mortality.
- It's linked with metabolic issues like insulin resistance, metabolic syndrome, dyslipidemia, inflammation, and vitamin D deficiency.
- This can lead to various comorbidities (other medical problems) increasing risk of falls, psychological issues (like depression), and further issues like knee osteoarthritis.
Potential Therapies for Sarcopenic Obesity
- Calorie restriction and improving physical activity may combat excess body fat and improve physical function.
- Aerobic and resistance exercises are useful in restoring muscle mass and function.
- Protein supplementation is often needed as a way to help mitigate muscle loss.
- Calcium, vitamins (like vitamin D), help in bone health.
Summary
- Physiological factors with decreased taste/smell, impaired metabolism, dysregulation of satiety, delayed gastric emptying, decreased gastric acid, and decreased lean body mass are common in older adults.
- Pathological issues like dental problems, digestive disorders (cancer, CHF, COPD, diabetes), medications (diuretic, antihypertensive, or anti-depressants), alcoholism, and dementia can impact older adult nutrition profoundly.
- Sociologic impacts like decreased ability to shop, prepare food, financial problems, lack of companions, and difficulty with daily living tasks impacting their nutritional intake.
- Psychological factors like depression, anxiety, loneliness, emotional stress, grief, and dysphoria, play a significant role in an older adult's nutritional behaviors.
Case Study Role Play
- A 86-year-old female presented with unintentional weight loss and various health conditions such as hypertension, cardiovascular disease, diabetes, transient ischemic attack, mild dementia, impaired vision, and hearing.
- She has experienced various medical conditions, including taking multiple medications such as blood thinners, diabetes medications, cholesterol medications, and more.
- The patient's daughter is present during the clinical encounter to assist in her health assessment.
- She indicated a change in appetite.
