Q

Goal of obesity in elderly treatment

Study These Flashcards
A
  • To better manage health and maintain independence longer
  • minimize loss of muscle mass
  • minimize loss of bone density
  • adequate nutrient intake
24
Q

How can you minimize loss of muscle mass in obesity treatment of elderly?

Study These Flashcards
A
  • adequate protein

- exercise (aerobic, resistance)

25
How can you minimize loss of bone density in obesity treatment in elderly?
- Adequate calcium, vitamin D | - exercise (weight bearing)
26
Basal energy expenditure in aging
Decreases with aging
27
Physical energy expenditure in aging
Greater decrease with aging
28
Protein requirement in elderly
- less efficient protein synthesis | - requirement greater than previous RDA (0.8gm/kg)
29
What reduces protein intake in elderly?
- poor dentition | - cost of protein rich foods
30
Aging related causes of increased protein need
- inadequate intake of protein - reduced ability to use available protein (insulin resistance) - greater need for protein (inflammatory disease)
31
What can decreased protein intake cause in elderly?
Loss of functionality | - muscle, bone, immune systems
32
Sarcopenia
- loss of skeletal muscle mass, strength and quality
33
Rule of thumb in elderly nutrition
- 1.0 - 1.25gm/kg/day - 25-30 gm protein/meal - at least 1 high protein food/meal - physical activity: aerobic and resistance (maintain CV system & muscle mass)
34
Why is there a higher calcium/vitamin D requirement in elderly
- high incidence of osteoporosis - less efficient absorption - reduced conversion of inactive D - reduced exposure to sun
35
Rate of osteoporosis in elderly
33% 60-70 y/o | 66% >80 y/o
36
What is the lowest mortality BMI in elderly?
27. 5 (considered overweight in adults) | - advantage to have extra weight!
37
T/F there is an increase number of people reaching older age as obese
True!
38
Rule of thumb of calcium intake in elderly
- 1000 - 1500 mg/day | - at least 1 dairy product/meal
38
Rule of thumb of vitamin D in elderly
- 600 IU w/ adequate sun exposure - 800 -1000 IU w/o adequate sun exposure - use vitamin D fortified products - encourage sun exposure 15-20 min/day - beneficial effect of weight bearing exercise
39
Vitamin and mineral needs in elderly differences from adults
- increased B vitamins (B6, B12) - increased Calcium & vitamin D - reduced iron (no menstruation)
40
What % daily value of vitamins should you have in adult/elderly multivitamin?
100% | Avoid mega supplement
41
Questions to ask regarding diet restriction in elderly
Will it have a negative impact on nutritional status? What is the significance of the restriction on longer term health outcome? Is there restriction practical for long term use?
42
Goal of diet restrictions in elderly
Liberal diet to encourage oral intake
43
Geriatric problems with nutrition
Sarcopenia Constipation Dehydration Swallowing
44
What is one of the most prevalent “perceived” problems in elderly?
Constipation
45
Why is constipation a problem in elderly?
Bowel motility decreases with age
46
Treatment of constipation in elderly
- dietary fiber >25g/day
47
Robertson’s rule of 2 in fiber intake
- 100% bran cereal: 1/2cup, 10-14g - whole wheat bread: 2 slices, 4g - fresh fruit: 2 pieces, 4g - veggies: 2 servings, 4 grams = 22-26g
48
T/f thirst sensations increase with aging
FALSE! | Decreases
49
T/f fluid requirements increase with increased fiber
True!
50
Fluids in elderly
Encourage fluid intake 8-10 cups/day
51
Dehydration causes in elderly
- decrease thirst sensation - increase dependence on others to obtain fluid - decreased ability to concentrate urine - increase incidence of incontinence (self-imposed fluid restriction) - increase use of medications contributing to dehydration - increase losses: vomiting, diarrhea, fever
52
Dehydration symptoms
- decreased skin turgor - dry mouth and mucosal membranes - decreased urine volume - darker urine - constipation - acute weight loss - CONFUSION
53
Dehydration treatment
- treat cause - set fluid goal - replace additional fluid losses - drink fluid at and b/t meals - use foods which have fluid value
54
What is the fluid goal in elderly?
30mL/kg or 1mL/Kcal
55
Swallowing symptoms (SWALLOWING)
``` S = swallowing difficult or hard to initiate W = wet sounding voice A = aspiration pneumonia in history L= loss of fluid through nose L = leakage of food or liquid out of mouth when eating O = overt coughing or choking with oral intake W = weight loss with inadequate nutritional intake I = involve speech pathologist N = nutrient density G = go for least restrictive ```
56
Practical application of swallowing in elderly
Be alert to symptoms Involve speech pathologist Fluid and nutrition density
