          Abstract

          Background: Self-medication of slimming supplements has increased, and media advertising has a role in this. The present study aimed at determining the effect of media literacy educational intervention on attitudes about self-medication of slimming supplements among the female students at dormitories of Iran University of Medical Sciences.

          Methods: In this quasi-experimental study with a control group, 98 students were selected by multistage cluster sampling method and were randomly divided into 2 equal groups of test and control. The data collecting instrument was a researcher-made questionnaire about media literacy and attitude on self-medication of slimming pills. Based on the results obtained from the early completion of the questionnaires, an appropriate educational intervention was designed and implemented. Data were analyzed 1 and 3 months after the intervention using the following statistical methods: repeated measurements, Friedman test, Chi square, independent T-test and MannWhitney test.

          Results: Before the intervention, the mean scores of attitude and dimensions of media literacy were moderate in both groups, and there was no significant difference between them. However, positive correlations were observed among attitude and knowledge (r=0.99, p= 0.001), critical thinking (r= 0.61, p= 0.001), and analysis (r= 0.37, p= 0.009) in the experimental group. The mean scores of attitudes and dimensions of media literacy were found to be significant in both groups 1 and 3 months after the intervention (p<0.05).

          Conclusion: Media literacy education was effective in promoting a positive attitude about slimming supplements.

          Use of dietary supplements for weight loss in the United States: results of a national survey.

          Christine Burton, T A Wadden, Rian J Pillitteri … (2008)
          We examined dietary supplement use for weight loss and perceptions about safety, efficacy, and regulatory oversight of these products. A random digit-dialed telephone survey was conducted in 2005-2006, with a representative sample of 3,500 US adults. The survey assessed the beliefs and practices related to weight control. Outcome measures included the prevalence of dietary supplement use for weight reduction, demographic profile of supplement users, and knowledge about safety, efficacy, and regulation of dietary supplements. Of the adults who made a serious weight-loss attempt (n = 1,444), 33.9% reported ever using a dietary supplement for weight loss. Supplement use was more common among women (44.9%) vs. men (19.8%); those aged 25-34; African Americans (48.7%) or Hispanics (41.6%) vs. whites (31.2%); less educated (38.4% high school degree or less vs. 31.1% some college or more); lower income households (41.8% made or =$40K); obese (40.7%) vs. overweight (29.1%); those who made more lifetime weight-loss attempts (42.0% made > or =3 vs. 22.1% made or =4 vs. 25.2% used <4). Many users and non-users of dietary supplements had misperceptions about these products-many believed they are evaluated for safety and efficacy by the Food and Drug Administration (FDA) before marketing, and that dietary supplements are safer than over-the-counter (OTC) or prescription medications. Use of dietary supplements for weight loss is common. More information about dietary supplements is necessary to correct misperceptions and encourage the use of safe and effective weight-loss methods.

            Association of cigarette smoking and media literacy about smoking among adolescents.

            S. Land, Vicki Gold, Eli J. Fine … (2006)
            To determine whether media literacy concerning tobacco use is independently associated with two clinically relevant outcome measures in adolescents: current smoking and susceptibility to smoking. We asked high school students aged 14-18 years to complete a survey that included a validated 18-item smoking media literacy (SML) scale, items assessing current smoking and susceptibility to future smoking, and covariates shown to be related to smoking. We used logistic regression to assess independent associations between the two outcome measures and SML. Of the 1211 students who completed the survey, 19% reported current smoking. Controlling for all potential confounders of smoking, we found that an increase of one point (out of 10) in SML was independently associated with an odds ratio for smoking of .84 (95% confidence interval [CI] .71-.99). Compared with students below the median score on the SML scale, students above the median had an odds ratio for smoking of .57 (95% CI .37-.87). Of the students who were nonsmokers, 40% were classified as susceptible to future smoking. Controlling for all potential confounders of smoking, we found that an increase of one point (out of 10) was independently associated with and an odds ratio for smoking susceptibility of .68 (95% CI .58-.79). Compared with students below the median SML, students above the median SML had an odds ratio for smoking susceptibility of .49 (95% CI .35-.68). In this sample of high school students, higher SML is independently associated with reduced current smoking and reduced susceptibility to future smoking.
