In a sampling of 205 hospital employees, 162 (79%) reported use of food supplements within the last two years. The user group was younger and had a higher proportion of females than the non-user group. Both groups showed a low level of nutrition knowledge; there was no significant difference in the knowledge scores between the two groups. However, the users had a significantly more internal score on the Locus of Control test. Even without the supplements, the diets of the users were better in fulfilling the RDA's of more nutrients than the non-users. The frequency of use of various supplements taken by the user group varied from a 1980 seven-state survey. In all cases, more of the current user group reported taking supplements than the seven-state survey participants.
