2. Differentiate between normal and 
disease-related changes in risk factors 
for undernutrition in older persons. 
3. Identify normal nutrition requirements 
of the older person. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Learning Objectives 
4. Analyze the causes and consequences

Learning Objectives 
6. Develop appropriate nursing

Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Introduction 
• Predictable changes can place older 
persons at a disproportionate risk of 
undernutrition, or malnutrition, 
compared to younger adults. 
• The wide spectrum of well-being in the 
older person presents nutritional 
challenges along a continuum. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Normal Changes in Aging 
• The normal aging process can result in 
biological changes that may place the 
older person at risk of malnutrition. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Changes in Body Composition 
• Lean muscle mass diminishes with 
aging. 
• Increase in body fat occurs. 
• Bone mineral density commonly is lost 
with age in both men and women. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Oral and Gastrointestinal Changes 
with Aging 
• Multiple changes may occur with age in 
the regulation of both appetite and fluid 
status. 
• There is a prevalence of constipation in 
the older person. 
• Aging blunts the thirst mechanism. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Sensory Changes 
• Age-related changes in vision, hearing, 
taste, and smell can have a negative 
impact on nutrition. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Social and Economic Changes 
Affecting Nutrition 
• Social isolation, loneliness, loss of a 
spouse, or bereavement can introduce 
additional influences that can alter 
adequacy of diet. 
• Changes in socioeconomic status may 
occur.

Box 5-2 Nutrition-Related Changes Associated With Aging 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Nutritional and Disease-related 
Health Changes 
• Many chronic diseases that affect older 
persons have nutritional implications 
for the disease and its treatment. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Nutritional Requirements and 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski 
Aging 
• The older person has some unique 
nutritional requirements due to the 
physical and functional changes that 
occur with aging. 
• The Modified MyPyramid makes overall 
recommendations for individual food 
groups to provide sufficient energy and 
nutrients together.
Nutritional Assessment 
• Both undernutrition and overnutrition in 
the older person can affect quality of 
life, morbidity, and mortality. 
• Assessment of nutritional risk factors 
for undernutrition should be routinely 
incorporated into the routine health 
screening of the older person. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Nursing Assessment 
• Nutritional screening and assessment 
tools exist to streamline the 
incorporation of nutritional status into 
routine healthcare processes. 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Common Nutritional Concerns in 
the Older Person 
• Unintentional weight loss 
• Medical nutritional therapy for chronic 
diseases 
Gerontological Nursing, Third Edition 
Patricia A. Tabloski
Nursing Diagnoses 
• Imbalanced nutrition 
– Less than body requirements 
• Imbalanced nutrition 
–More than body requirements 
• Deficient knowledge 
–Related to diet 
• Noncompliance to diet
