Facebook may contribute to promoting unhealthy food to teens and young adults
Social media sites like Facebook can contribute to marketing unhealthy foods to young people, according to new research from the American Journal of Public Health.
Researchers investigated the extent to which energy dense, nutrient-poor foods are promoted and marketed using social media tools and strategies. The Australian-based study used a sample of top-ranked Facebook pages of food manufacturers, food brands, retailers and restaurants. The resulting analysis reviewed 27 food and beverage brand Facebook pages on the basis of their marketing techniques, follower engagement and marketing reach of messages posted by the pages.
Results from the study find a high level of engagement between energy-dense, nutrition-poor food companies and adolescents and young adults on Facebook. In addition, the study’s analysis shows a prevalence of highly engaged users sharing the content onward within their personal social networks. Users require little incentive to engage with the products. Results further showed that competitions, giveaways and aligning with positive events were found to be effective means of engagement between users and the food companies.
“In terms of health policy, much of the current work to limit exposure to [energy-dense, nutrition-poor food] advertising is focused on restricting advertisements during children’s television programs and viewing hours. Our study shows that this narrow focus is likely to miss large amounts of online advertising aimed at adolescents,” the researchers suggest.

‘Stop and frisk’ policing associated with trauma and anxiety among young urban men
New research from the American Journal of Public Health finds that young urban men who experience invasive proactive policing are likely to experience more trauma or anxiety symptoms.
Researchers surveyed more than 1,200 New York City young men age 18 to 26, between September 2012 and March 2013. The sample was based on the local population and selected to include both high- stop and low-stop areas of the city, and men with and without personal experience with the police. Participants were asked about whether or not they had been stopped by the police, the frequency of the occurrences and details about the encounters, including whether physical force or threats took place. Participants also responded to questions on mental health assessing symptoms of trauma including a measure of post traumatic stress disorder and anxiety levels.
Findings from the study indicate that individuals who experienced more proactive policing practices, particularly those who experienced invasive policing, such as being thrown to the ground or slammed against walls, were likely to report more trauma or anxiety symptoms. This relationship was particularly pronounced for respondents reporting the most intrusive experiences.
“This raises concerns that the aggressive nature of proactive policing may have implications not only for police-community relations but also for local public health,” the study explains.
“Notwithstanding the dearth of evidence to justify a crime-control claim, and the constitutional concerns these arguments raise, our findings suggest that any benefits achieved by aggressive proactive policing tactics may be offset by serious costs to individual and community health,” the researchers charge.

Cellular aging could be impacted by sugar-sweetened soda intake
Consuming sugar-sweetened sodas is associated with additional cellular aging, according to new research from the American Journal of Public Health. Sugar-sweetened soda consumption could impact leukocyte telomere length in a magnitude comparable to smoking. Shorter telomeres have been associated with risk of chronic diseases like cardiovascular disease and diabetes.
The study analyzed the potential impact of consuming sugar-sweetened sodas, non-carbonated sugary beverages, diet sodas and 100 percent fruit juice on leukocyte telomere length. Researchers used data from the 1999-2002 National Health and Nutrition Examination Surveys, which included collection of 24-hour dietary recalls and DNA specimens for more than 5,000 participants between the ages of 20 and 65. Researchers estimated usual intakes of various beverages and compared it alongside telomere length measured from the DNA specimens.
Results from the study indicate an association between telomere length and consumption of sugar-sweetened sodas. According to the findings, 20-ounce serving of sugar-sweetened soda, a typical serving size today, could result in 4.6 years of cellular aging. This magnitude of cellular aging is comparable to the beneficial aging effects of moderate or vigorous levels of physical activity, which would lengthen telomeres, and the negative aging effects of smoking which would shorten them, as shown in other published studies. In this study, more than 20 percent of study participants reported dietary intake of 20 ounces of soda per day, underscoring how common soda-related telomere shortening may be.
“It is critical to understand both dietary factors that may shorten telomeres, as well as dietary factors that may lengthen telomeres. Here it appeared that the only beverage that had a measurable negative association with telomeres was sugared soda. This relationship was robust, across age, sex, race, and economic levels.” Cindy Leung, ScD, the lead author explains.
“We already know too well that soda consumption contributes to obesity. This study reveals a new link, suggesting soda may also lead to shortened immune cell telomere length, independent of levels of obesity. Shortened telomere length is a risk factor for earlier onset of a vast array of diseases of aging” said Elissa Epel, PHD the senior author.
