Outline
• Conceptual Framework for Supplementation• Summary of Evidence
– Multivitamins and Minerals– Antioxidants– Herbal Preparations– Nutraceuticals– Hormonals

Conceptual Framework
![Page 4: Use of Supplements in the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022081401/557d5af1d8b42abf3d8b4bea/html5/thumbnails/4.jpg)
Contributors to risk of malnutrition
• The elderly are at higher risk of developing protein-calorie malnutrition and other vitamin and mineral deficiencies.
• The frequency of these events increases with advancing age due to problems such as poor dentition, loss of taste, difficulty swallowing, malabsorption, and drug-nutrient interaction
![Page 5: Use of Supplements in the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022081401/557d5af1d8b42abf3d8b4bea/html5/thumbnails/5.jpg)
Contributors to risk of malnutrition
• Other physical limitations such as inability to obtain necessary food due to lack of transportation and dependence on others for shopping, lack of financial resources, and functional limitations can contribute to nutritional deficiencies
![Page 6: Use of Supplements in the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022081401/557d5af1d8b42abf3d8b4bea/html5/thumbnails/6.jpg)
Contributors to risk of malnutrition
• Non-perishable foods frequently contain high amounts of sodium and nitrates, and processing can remove vitamins.
• Many drugs cause anorexia, gustatory changes, and anosmia as major side effects.
• Medications can also interfere with nutrient availability
![Page 7: Use of Supplements in the Elderly](https://reader036.fdocuments.net/reader036/viewer/2022081401/557d5af1d8b42abf3d8b4bea/html5/thumbnails/7.jpg)
Risk Factors for Poor Nutrition Status
Alcohol or substance abuse Limited mobility, transportation
Cognitive dysfunction Medical problems, chronic diseases
Decreased exercise Medications
Depression, poor mental health Poor dentition
Functional limitations Restricted diet, poor eating habits
Inadequate funds Social isolation
Limited education

Physiology-the “anorexia of aging”

Physiology
• Changes in body composition– Decreased bone mass– Decreased lean mass– Decreased water content– Increased total body fat (greater intra-abdominal fat
stores)
• Decline in organ function is highly variable among individuals and may affect assessment and intervention options

Vitamin B12 in Cognitive Decline
• there does appear to be an association between elevated plasma homocysteine levels (a by-product of B vitamins) and the onset of dementia (very low quality evidence).
• treatment with B12 supplementation does not appreciably change cognitive function (moderate quality evidence, but with less than optimal duration of follow-up)
• treatment with vitamin B12 and folate in patients with mild cognitive impairment seems to slow the rate of brain atrophy (low to moderate quality of evidence)
• oral vitamin B12 is as effective as parenteral vitamin B12 in patients with confirmed B12 deficiency (moderate quality evidence).

• Results– For all pseudoroughness and microrelief indicators, there
was a significant increase from baseline to month 4 in the placebo group (P,0.05)
– a significant and dramatic difference between baseline and month 4 and between baseline and month 5.5 (P,0.05) in the active group, indicating decreasing anisotropy of the skin
– skin thickness was significantly decreased in the placebo group during winter but was stable in the treated group (P,0.01).
– The photography scaling and self-assessment questionnaire revealed no significant changes in either group.
