![Page 12: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/12.jpg)
Geriatric Problems
• What geriatric problems impact nutritional status?
![Page 13: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/13.jpg)
Sensory Changes with Aging
![Page 14: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/14.jpg)
Sensory Changes with Aging
• Decreased sense of smell due to decreased olfactory cells
• Decreased vision
• Hearing loss
• Tactile loss
![Page 15: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/15.jpg)
Sensory Changes with Aging
• Decreased number of taste buds– Loss of sweet
and salty– Less loss of bitter
and sour– ? Umami– ? Piquant– Dry mouth prevents
adequate tasting
![Page 16: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/16.jpg)
Psycho-Social Changes of Aging
![Page 17: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/17.jpg)
Psycho-Social Changes of Aging
• Economic– Less income; less money for food
• Social – Lack of Socialization– Loss of mobility; can’t drive– Loss of friends and loved ones
• Psychological– Loss self-worth; value– Depression; BIG problem (Bayer quote)
![Page 18: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/18.jpg)
Depression ……………The attitude that:
“Of course he/she is depressed, I’d be depressed too if I were that old and had all those problems…..”
puts elderly at risk of not receiving clinical attention for a very treatable disorder. Just because it is “understandable”, does not mean that depression is inconsequential or normal as people age.
Barb Bayer, RN, MSN, CS
![Page 19: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/19.jpg)
Depression …………… is the most common psychiatric condition
affecting the elderly, but it is often unrecognized and untreated. The myth that depression is just a natural part of aging is widespread in our youth-oriented society. It is also a belief held by many elderly themselves, their families, and unfortunately, many health care professionals.

Strategies: Calories
• Energy needs are dependent on activity and physiologic stress levels
• 25-30 kcal/kg
• Basal Energy Equation X factor of 1-1.5– Harris Benedict Equation– Mifflin St-Jeor Equation (Currently recommended)
Rule of Thumb
![Page 29: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/29.jpg)
Strategies: Calories
• Avoid unnecessary dietary restrictions • Encourage use of
nutrient dense foods
• Use more frequent meals plus supplements or snacks
![Page 30: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/30.jpg)
Strategies: Calories
• Use foods that are well liked frequently • Provide double portions of favorite foods • Add calories by using sauces, gravies, toppings, and fats• Emphasize calorie containing liquids to meet fluid needs
Practical Suggestions
![Page 31: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/31.jpg)
Obesity
• numbers reaching older age as obese (30.5% in NHANES)
• physical and cognitive disability
• risk of dependency and institutionalization
• health care costs, poor health outcomes, mortality
Houston, et al, JADA, Nov. 2009
![Page 32: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/32.jpg)
Obesity Treatment
• Goal: To better manage health and maintain independence longer
• Minimize loss of muscle mass– Adequate protein– Exercise (aerobic and resistance)
• Minimize loss of bone density– Adequate calcium, Vitamin D– Exercise (weight bearing)
• Adequate nutrient intake
![Page 33: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/33.jpg)
Sarcopenia
• Definition: Loss of muscle mass in aging.
• Results: Lower basal metabolic rate – Weakness -Decreased Functional Status– Reduced Activity Level– Decreased Bone Density
• Practical Application– Progressive Resistance Exercises– Adequate Protein

Nutrients of Concern in the Elderly
• Calories– Nutrient Density
• Protein• Calcium• Vitamin D• Supplements?
• Don’t forget– Fiber– Fluids
![Page 68: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/68.jpg)
Osteoporosis •High incidence of osteoporosis
–33% of women 60-70 years old–66% of women > 80 years old
•Less efficient absorption of calcium and Vitamin D•Reduced exposure to sun =
reduced conversion of inactive D to active D•Supplementation essential
–1200-1500 mg/day
![Page 69: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/69.jpg)
Vitamin D
• Most tissues and cells have Vitamin D receptors
-Skeletal muscles, brain, prostate, breast, colon, immune cells
• Active D controls more than 200 genes which are responsible for:
-Cell proliferation, differentiation, apoptosis, angiogenesis
• Potent immunomodulator
![Page 70: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/70.jpg)
Serum 25-hydroxyvitamin D
• <20 ng/mL Deficiency
• 20-29 ng/mL Insufficiency

Appetite Stimulation
Sensory Changes with Aging
• Decreased sense of smell due to decreased olfactory cells
• Decreased number of taste buds
• Decreased vision

Appetite Stimulation
Benefits to Increasing Appetite
• Reverse anorexic cycle– Failure to eat– Ketone build up – Loss of appetite
• Promote Nitrogen Balance
• Further stimulate appetite
• Consider tube feeding; night feeding

Appetite Stimulation: Research
• Megestrol Acetate (MA)• N= 51 men; Average Age 76• Weight loss > 5% in 3 months or > 20%
below “ideal” weight• 800 mg MA/day• 12 weeks on MA; 13 weeks off MA• Weighed monthly• Control – no MA
![Page 85: Nutrition and the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022062518/56813fae550346895daa944b/html5/thumbnails/85.jpg)
Research Results
• 12 weeks on MA – No significant wt. gain
• 13 weeks after MA – Wt. gain (> 4#) was significantly increased in MA patients
• 38% of MA pts did not gain wt; wasted, advanced dementia; more medical conditions; greater than 10 medications
• All who gained wt, gained lean body mass
• ?? Functional Benefit ??

Research Conclusions
• In geriatric patients, MA may promote weight gain, but anticipate a delayed response
• Initiate treatment early
• 800 mg was tolerated by elderly patients

Vitamin A Intake
• Vitamin A directs the process of borrowing and redepositing calcium in the bone
• Too much preformed Vitamin A (retinol) can promote fractures.
• Use Vitamin A in form of beta-carotene, a pre-curser form which does not increase fracture
