Module 2 - Geriatric Nutrition, Hydration, and Mental Health Flashcards
The ABC’s of Nutrition for the Elderly
Aim for fitness
Build a healthy body
Choose sensibly
(We use these to help the elderly to stay in good nutrition)
What is a very important factor for later ability to recover from disease and illness?
Lifelong eating habits
What are the important congressional acts to know relating to elder nutrition?
Omnibus Budget Reconciliation Act of 1987 (OMBRA)
Balanced Budget Act of 1997
What was the main purpose of the OMBRA and Balanced Budget Acts?
To impact nutritional standards in LTC facilities regarding BMI, weight, I/O, hydration, pressure injuries
If you cannot follow these standards there will be monetary fines and government benefits can be removed - LTC can lose their normal reimbursement amount
Factors that contribute to malnutrition in the elderly?
Normal Physiologic Changes
Oral and GI Changes - motility slows with age and they may be edentulous or using dentures
Sensory Changes - may not hear as good or smell/taste as well
Social and Economic Changes - SS reliance –> tough decisions on rent v food, etc
Sarcopenia (Sarcopenia Obesity)
Decreased lean muscle mass
How can sarcopenia come about?
Decreased Physical Activity
Sedentary Lifestyle
Decreased Nutrition
Decreased Anabolic Hormones
Can obesity occur alongside sarcopenia?
YES
What does the vicious cycle of Sarcopenia occur?
Sarcopenia –> Functional Decline –> Loss of Strength –> Additional Loss –> Increase in Morbidity and Mortality –> REPEATS FROM SARCOPENIA
Oral and GI Changes that contribute to Malnutrition in the Elderly
Xerostomia
Dysphagia
Decreased Thirst Perception
Altered Dentition
Altered Taste and Smell
Decreased Gag Reflex
Decreased Peristalsis, Gastric Secretion and Motility (Constipation)
Altered Appetite - Anorexia of the Aging
What contributes to Altered Appetite / Anorexia of the Aging?
Increase cholecystokinin and early satiety
Stomach decreases in size
Xerostomia
dry mouth
try to encourage fluids with this
Dysphagia
Difficulty swallowing
could be from something like stroke or another illness

Everything ___ ___ with age!
slows down
Do older adults present in a similar way like an adult patient?

What are some social and economic changes in the elderly that leads to malnutrition?
Social Isolation
Loneliness
Depression
Sedentary Lifestyle
“Food Insecurity” r/t insufficient funds
Why is social isolation and loneliness so prevalent in the elderly, and why does it contribute to malnutrition?
- Living location - 25% live in a rural area in the middle of nowhere and therefore it may be easier to go to a nearby gas station rather than a grocery store farther out
- Deaths of spouses and children moving out
- Caregiver may be just as old as them and not even be able to effectively care for themselves
How does depression contribute to malnutrition?
Depression and Loneliness –> Less desire to eat –> Older people are lonelier and their appetite leaves
How can a sedentary lifestyle for the elderly contribute to malnutrition?
Sitting all day or inability to ambulate may make it so people only live off candy, soda, cookies, coffee, etc
What is Food Insecurity ?
Insufficient funds makes it so a person has to choose between things (ex: rent, food, medications, etc) and may not be able to afford good nutrition
They end up making prioritization choices since they are living off of social security - which is not enough
