Attitudinal and demographic correlates of food supplementation practices.

Attitudinal and demographic correlates to food supplement use were ascertained for 689 adults residing in seven Western states. Of the 689, 372 (54%) were food supplement users and 317 (46%) were non-users. The only attitudinal variable significantly (p less than .001) related to the practice of food supplementation was the belief that vitamin C could cure and prevent a cold. More users than non-users agreed with the statement that "vitamin C can both prevent and cure a cold." Demographic variables found to be significantly (p less than .05) related to food supplement use included education, marital status, home type, employment status, and population of town/city in which the respondent resided. Food supplement users tended to be living together without marriage, never married, or divorced and living in town houses or "other" types of dwellings. More users than non-users resided in communities with populations of 2,500 or in communities with populations of 10,000 to 49,999.
