The impact of sociodemographic, health-related, and behavioral variables on the dietary adequacy of the younger old (65 to 84 years, N = 2496) and oldest old (85 years and older, N = 159) was investigated using data from the Nationwide Food Consumption Survey 1977-78. The percent of individuals with poor diets (defined as mean three-day intake below 67% of the 1989 Recommended Dietary Allowances for at least five of the nine nutrients examined) was greater for women (18%) than for men (13%) and for the oldest old (21%) than for the younger old (16%). Better diet quality was associated both with increased quantity and with increased nutrient density of diets. Multivariate analyses identified two factors of importance for nutrient quality for both the younger and oldest old: mean energy intake and percent of calories from ready-to-eat cereal. Positive predictors of energy intake for both age groups included: number of meals, percent of calories from snacks, and money per person spent on food by the household. These results suggest that nutritional guidance for older Americans should focus on maintenance of adequate (but not excessive) energy intakes by consuming three meals a day plus snacks. Selection of foods of high nutrient density, such as fortified ready-to-eat cereals, should be emphasized, particularly when energy intakes are low. Nutrition programs should target individuals at risk of low food intakes: women, the oldest old, and persons in poor health, on weight-loss diets, or with inadequate money for food.
