Living arrangements and dietary quality of older U.S. adults.

The association between living arrangement and dietary quality of older U.S. adults was investigated in 4,402 adults aged 55 years or older who participated in the Nationwide Food Consumption Survey, 1977 to 1978. Dietary quality was based on percent of Recommended Dietary Allowances for 3-day intakes of nine nutrients. More men living alone consumed a poor-quality diet than did men living with a spouse, particularly those 75 years or older; for women, this effect was seen only in the 55- to 64-year-old group. In general, more women than men had poor-quality diets. A number of factors (economic, employment, health status, energy intake, body mass index, and nutrient supplement use) were examined for their importance in accounting for differences in dietary quality of older men and women living alone compared with those living with a spouse. Energy intake was the most important variable accounting for the association of living arrangement with dietary quality. Evidence indicated that older adults living alone did not make poorer food choices than those living with a spouse, but rather that they consumed fewer calories.
