Perceptions related to dietary supplements among college students

Abstract

The aim of this study was to increase understanding of how college students perceive dietary supplements, including their experiences with and attitudes about these substances. This study used a qualitative case study design and content analysis of web log (blog) posts completed as an assignment in an undergraduate nutrition course. Students were asked to submit one initial post and at least five comments about dietary supplements using a blogging tool. Blog posts were coded and analyzed. The most commonly mentioned categories were explored, which revealed four main categories: supplements discussed and/or used, rationale for use, sources of information, and perceptions of the safety of supplements. The most commonly mentioned supplements were multivitatmins, diet pills, and protein supplements. The most frequently reported reason for supplement use was a perceived lack of nutrients in the diet. Information about dietary supplements came mainly from friends' or family members' experiences. Many students had misconceptions about supplements, were not familiar with them, and/or questioned their effectiveness. Based on the study findings, educational programs for college students should focus on common misconceptions; the safety and efficacy of supplements, especially diet pills and protein supplements; critical analysis of supplement information; and the appropriateness of supplement use.Grant Funding Source: none
