The Nutritional Health for the Elderly Reference Centre Study (NHERC Study)

Elderly are at greater risk of dietary insufficiency due to age-related increases in nutrient requirements concomitant with a reduction in energy requirements, decreases in appetite and energy intake. Currently there is a gap in knowledge of the factors that are associated with malnutrition in the elderly in Singapore. In addition, there is no "reference" database on anthropometric measurements and biochemical indices for elderly with a range of nutrition status in Singapore. Thus, the objectives of this cross-sectional study are to examine factors influencing nutritional status and to determine the reference values for anthropometric and biochemical measurements related to nutritional status for community-dwelling elderly in Singapore.

This is a cross-sectional study. Measurements will be taken at baseline for elderly with normal nutrition (n = 400) and elderly who are at risk of under nutrition (n = 800).. These measurements will be used to examine factors influencing nutritional status and to create a "reference" database for anthropometric and biochemical measurements related to nutritional status for use in clinical practice.
