Assessing Nutritional Status
Factors Impacting Nutritional
Status in the Elderly
Assessing Weight Status

BMI


Percent Weight Loss (unintended)




<23 considered underweight >65 yrs
>5% in 1 month (quadruples risk of death)
> 7.5% in 3 months
>10% in 6 months
Cachexia

Severe wasting accompanying diseases such as cancer
Mini Nutrition Assessment




6 question screening
tool
Complete in <5 minutes
Validated for age >65
More sensitive than BMI

Sarcopenia

Sarcopenia




Loss of skeletal muscle associated with aging
Affects 8-40% of adults >60 yrs
50% of adults >75 yrs
Sarcopenic Obesity

Coexisting loss of skeletal muscle mass
and strength with excess body fat
Nutritional Needs of the Elderly
Energy




Energy (calorie) needs decrease with age,
mostly due to decreased physical activity
LBM declines with age and influences
energy needs
Protein and vitamin/mineral needs remain
the same or increase
Challenge: adequate micronutrients within
caloric requirement
Nutrients of Concern

Risk for deficiency with age
Water
 Fiber
 Protein
 Calcium and Vitamin D
 Vitamin B12
 Vitamin C and E – antioxidants

Water
Dehydration is a form of malnutrition
 Kidneys’ decreased ability to
concentrate urine
 Adverse effects of medication
 Mobility disorders
 Fear of incontinence
 25-30 mL/kg actual body wt

Fiber

Fiber Goals for adults over 50:



Insoluble: Tough, fibrous plant material
that does NOT absorb water


Men: 30 g per day
Women: 21 g per day
Most grains and vegetables
Soluble: Plant fibers capable of absorbing
water and become gummy or gel-like

Oats, fruit, legumes, pectin, inulin, psyllium
Sources of Fiber
Oats
Barley
Wheat
Quinoa
Flax
Brown Rice
Bran
Legumes
Seeds
Fruits
Vegetables
Protein
Muscle mass (LBM) decreases 15%
per decade after age 70
 Needs increase with illness, injury



Surgery, wounds, CHF, COPD, Cancer
Optimal intake: 25-30 gm/meal
 Even
distribution most effective in preventing
muscle loss during illness

1-1.6 gm/kg IBW may prevent
sarcopenia
PROTEIN
Sources:

Animal Proteins


Dairy


Milk, Cheese, Yogurt, Cottage Cheese…

Calcium
1000 mg Men <70 years

calcium supplements don’t prevent
hip fractures


Vitamin K


Manganese



phosphorus decrease calcium
availability.
