Nutrient intakes and dietary patterns of older Americans: a national study.

To assess the dietary status of older Americans, a national household survey of food consumption practices of individuals 65 years of age and older was conducted in May-August, 1990. The design and methodology of the survey were modeled after those of the USDA's Continuing Survey of Food Intakes by Individuals (CSFII). Dietary information for 474 individuals (65 to 98 years of age) in 355 households was collected by interview (24-hour dietary recall). Analyzed indicators of dietary quality were energy (calorie) and nutrient intake, food group intake and frequency, and number of meals skipped. Results indicated that substantial percentages of those surveyed had inadequate intakes of energy and nutrients. Over 40% of men had intakes of vitamins A and E, calcium, and zinc below two-thirds the RDA. For women, over 40% had intakes of vitamin E, calcium, and zinc that were below two-thirds the RDA. Additionally, over 20% of older men and women skipped lunch. These data indicate that a large proportion of noninstitutionalized elderly Americans consume diets that fail to meet dietary standards.
