Abstract

Background: The elderly population is increasing worldwide, which warrants their nutritional status assessment more important. The present study was undertaken to establish the nutritional status of the least-studied elderly population in Pakistan.

Methods: This was a cross-sectional study with a sample of 526 generally healthy free-living elderly men (mean age: 68.9 yr; range: 50-98 yr) from Peshawar, Pakistan. Anthropometric measurements (weight, height, WC) were measured and BMI and WHR were calculated from these measurements following WHO standard procedures. Dietary intake was assessed by 24-hr dietary recall. Nutrients were calculated from the information on food intake. Nutrients in terms of % of RNI were calculated using WHO data on recommended intakes.

Results: Based on BMI, the numbers of obese, overweight and underweight elderly were 13.1, 3.1 and 10.8%, respectively. Age was negatively and significantly correlated with BMI (p = 0.0028). Energy (p = 0.0564) and protein intake (p = 0.0776) tended to decrease with age. There was a significant increase in % BF with age (p = <0.0001). The normal weight elderly had significantly (p < 0.05) higher intake of all nutrients studied, except energy which was significantly (p < 0.05) higher in obese and overweight elderly. Overall, however, the majority of subjects had lower than adequate nutrient intake (67.3 - 100% of recommendation).

Conclusions: Malnutrition is common in apparently healthy elderly Pakistani men. Very few elderly have adequate nutrient intake. Obese and overweight had higher % BF as compared to normal weight elderly. Older age is associated with changes not only in anthropometrics and body composition but also in intake of key nutrients like energy and protein.
