Abstract
A popularity in slim body and white skin, resulting in the increasing use of beauty food supplements, is a worrisome health issue among Thai teenagers. An important factor influencing these supplement use behavior is the media. It enhances the use of these beauty supplements without concerns about any negative consequences. There is a need for improving media awareness and media literacy among the teenagers. Objective: The purpose of this study was to evaluate the media literacy program for beauty food supplements among high school students. Methods: We conducted a pretest-posttest, stratified randomization, randomized controlled trial. Participants were 11th grade students of Sansaiwittayakom School, Chiang Mai. The 55 students were stratified by their major and sex, then randomly assigned to a control group (28) and an intervention group (27). The intervention group received a media literacy program containing five activities including 1) recreation activities for breaky the ice 2) activities about media accessing and media literacy 3) activities about evaluation of beauty food supplements 4) giving information about beauty food supplement and 5) activities on sharing information about beauty food supplements to other people. Data was collected by a questionnaire containing items assessing knowledge of the beauty food supplements, investigation skills regarding the advertisement, self-efficacy and risk perception, about safety, value and social acceptance. Descriptive statistics and inferential statistics were used. Results: The results showed that an intervention group had a significantly higher self-efficacy score than a control group (different of mean ± SD: 2.11 ± 3.63 vs -2.93 ± 6.87; P = 0.009). Similarly to the knowledge of the beauty food supplements, only in a case of L-carnitine, an intervention group had a significantly higher score than a control group (different of mean ± SD: 1.26 ± 1.16 vs 0.57 ± 1.29; P = 0.040). However, the investigation skills regarding the advertisement and the risk perception about safety, value and social acceptance were not significantly different (P > 0.05). Conclusion: The media literacy program for beauty food supplement can improve among high school students media literacy and self-efficacy.
