Green tea is a popular beverage believed to have many health benefits, including a reduction in the risks of heart disease and cancer. Rich in polyphenolic compounds known as catechins, green tea and its components have been shown to increase the lifespan of various animal models, including Drosophila melanogaster. Here, we investigated the genderspecific effects of green tea on the lifespan of fruit flies and observed that green tea extended the lifespan of male flies only. This effect was found to be independent of typical aging interventions, such as dietary restriction, modulation of oxidative energy metabolism, and improved tolerance to environmental stresses. The one exception was that green tea did protect male flies against iron toxicity. Since there is an inverse correlation between lifespan and reproduction, the impact of green tea on male reproductive fitness was also investigated. We found that green tea negatively impacted male fertility as shown by a reduced number of offspring produced and increased mating latency. We further identified that the lifespan extension properties of green tea was only observed in the presence of females which alludes to a reproductive (or mating) dependent mechanism. Our findings suggest that green tea extends the lifespan of male flies by inhibiting reproductive potential, possibly by limiting iron uptake. To our knowledge, our study is the first to report the negative impact of green tea on Drosophila male reproduction. Our results also support previous studies that suggest that green tea might have a negative effect on reproductive fitness in humans.

BackgroundIn the late 20th century, US localities began increasing the minimum age of legal access (MLA) for tobacco from 18 to 21 years by enacting “Tobacco 21” ordinances. Although these policies have a strong evidence base and broad popular support, popular media coverage of tobacco control laws has not always been accurate. This study sought to determine if contemporaneous popular media reporting accurately reflected the scientific findings regarding increased tobacco MLAs.MethodsWe searched LexisNexis for popular media reports that (1) addressed proposed or enacted Tobacco 21 ordinances and were (2) published in English, (3) drawn from a US news source, and (4) written after January 2004. We conducted a content analysis for quality based on a validated measure of accuracy of reporting, the Index of Scientific Quality (ISQ), which allows assessment of articles by assigning scores ranging from 1 (lowest) to 5 (highest).ResultsSearches yielded 378 articles; after screening for relevance and duplicates, 98 were included in the review. All studies identified through the keyword searches addressed Tobacco 21 policies. The average global score identifying the scientific quality of the articles was 2.98 of 5. Over three-quarters of the popular media articles addressing Tobacco 21 laws were written after a systematic review of these policies was released by the Institute of Medicine and approximately 4 in 10 cited findings from that review.ConclusionsPopular media reports on Tobacco 21 laws demonstrated average overall quality and relied on both anecdotal and scientific evidence, in contrast to previous studies found that popular media reports on tobacco issues demonstrated low overall quality and relied primarily on anecdotal evidence. The systematic review of increased MLAs for tobacco written by the Institute of Medicine diffused quickly into popular reporting, suggesting that this type of evidence might improve research translation.

Background and Purpose: College and university tobacco control programs have historically neglected cessation. In 2012, the University of California Office of the President (UCOP) released a Smoke and Tobacco Free policy that became effective in January 2014. The policy provided for a comprehensive education and outreach campaign that included resources and referrals for cessation. We sought to determine whether all University of California (UC) campuses met UCOP standards. Methods: We reviewed the Smoke & Tobacco Free policies created by UCOP and posted at ten UC campuses, searched the tobacco free websites of each campus for cessation resources, and contacted tobacco-free task forces. Results: We found that all UC campuses met the UCOP standard by addressing tobacco cessation in their campus policies. The provision of cessation services and resources was limited and varied substantially by campus, and no campuses reported collecting data on the use of cessation programs. Conclusion: Consistent with concerns that college and university tobacco policies neglect cessation, UC campuses mentioned tobacco cessation resources and programs but did not provide consistent services. These campuses also did not report on the use of tobacco cessation resources, making it difficult to assess the effects of offering different types of cessation programs.
