THE PROCESS OF AGING
In 2040, 25% of the Dutch population is 65 + We are getting older
Therefore it is essential to gain an insight in the nutritional needs of elderly.
Because: optimal nutrition contributes to the quality of life in the last years

AGING Aging is not a homogenous process.
Organs in the same person age at different rates influenced by
Genetic-make up Lifestyle choices Environmental choices
AGING
AGING AND GASTRO INTESTINAL SYSTEMWhat does it affect?
Swallowing and chewing aspiration Decline in taste and smell Increased rates of gastritis and increased
sensitivity to medication Changes in intestine structure; less effective
uptake of micronutrients (Vit B12) Less vitamin D receptors lower efficiency of
calcium absorption. Reduced propulsive motility obstipation Reduced anal sphincter tone fecal incontinence
HOMEOSTENOSIS
MALNUTRITION
Risk of
malnutrition
Loss of appetite----------
Lower Energy requirement
Decline in Energy intake
Increase in fat massDecline in muscle mass
↓ Exercise
WHO IS AT RISK OF MALNUTRITION? Elderly Chronic disease
Cancer COPD Heart failure Kidney failure
WHAT ARE THE CONSEQUENCES OF MALNUTRITION?
HOW LARGE IS THIS GROUP? < 1500 Kcal/day ; High risk of micronutrient
deficiency.
20 % of people > 75 year who living independently
40% of elderly living in a nursing home
HOW DO RECOGNIZE SOMEONE AT RISK? By weighing!
Weight loss: > 5% in 1 month (3 kg/month) > 10% in 6 months (6 kg/month)(independent of the initial weight)
< 65 year: BMI < 18,5 kg/m2 > 65 year: BMI < 20,0 kg/m2
MAJOR BOTTLENECKSVitamin D deficiency! (sunlight)
Water Proteins Vitamin A Vitamin B6, Folic acid, Vitamin B12 (due to
malabsorption) Vitamin C Calcium (diuretics) Iron Iodine

Independent elderly < 50 nmol/l 50% 35% 50%
Nursery home < 50 nmol/l 0 – 85%
SENIOR FRIENDLY HOSPITAL30-60% of the elderly experience a decline in health while admitted to the hospital
Hospitals should become senior friendly:‘Look beyond the reason of admission’
4 year project to a. identify the needs and
requirements of elderly when it comes to hospital admission / visits
b. Identify each hospital policyc. Reward positive results with the
label ‘’senior friendly hospital “d. Advising hospitals on senior
friendliness
Goal: At the end of 2015 everyone in Holland knows where to find a senior friendly hospital
