Abstract

BackgroundThe prevalence of dietary supplement DS advertisements in non-English daily periodicals, weekly periodicals, and television in the United States is unknown. Additionally, it is unclear if the claims presented in these advertisements are validated. This study aims to compare the prevalence of DS advertisements and percent of validated claims in DS advertisements among popular English and non-English daily periodicals, weekly periodicals, and television.

MethodsThis is a cross-sectional study involving daily periodical, weekly periodical, and television advertisements for DS in English, Spanish, Chinese, and Korean in San Francisco Bay Area and Los Angeles Area, California, USA. Study outcomes are percent prevalence of DS advertisements, percent of claims in DS advertisements that made therapeutic claims, and percent of validated claims in DS advertisements. Claims in DS advertisements were validated by using the effectiveness rating of the Natural Medicines Comprehensive Database and-or identifying a supporting randomized controlled trial RCT.

ResultsThe prevalence of DS advertisements across all three media outlets were 0 % in English, 0 % in Spanish, 14.8 % in Chinese, and 11.4 % in Korean. Across all three media outlets, DS advertisements were significantly more prevalent in both Asian languages than in English p < 0.001. None of the products identified in English media outlets made a therapeutic claim whereas 18.6 % of products identified in non-English media outlets did. None of the claims in DS advertisements had an effective rating. Only one product identified in English media outlets had supporting data from an RCT.

ConclusionsOur data suggest that DS advertisements are more common in Asian language media outlets than in English and Spanish language media outlets. Given the lack of validated claims in DS advertisements, rigorous evaluations of their claims should be carried out to guide and protect consumers.
