The rise of smart phones, tablets, and other mobile technologies has put digital media, quite literally, at the fingertips of today’s youth. Most teens now have ready access to a smartphone, with about half spending the majority of their waking hours texting, checking social media sites, watching videos, or otherwise engaged online [1].

So, what does this increased access to digital media—along with the instant gratification that it provides—mean for teens’ health and wellbeing? In a two-year study of more than 2,500 high school students in Los Angeles, NIH-funded researchers found that those who consumed the most digital media were also the most likely to develop symptoms of attention-deficit/hyperactivity disorder (ADHD) [2].


Is Social Media Making Us Lonelier?

Social mediaInitially, most of us thought that Facebook, Instagram, Twitter, and other social media applications would help to bring people together. And, yes, in many instances that has been true. Such apps have made it possible—even simple—to catch up with former classmates living thousands of miles away, share a video of your baby’s first steps with relatives near and far, or strike up new acquaintances while discussing the stock market or last night’s ballgame. Yet, a new NIH-funded study suggests that social media may also have the power to make people feel left out and alone.

Based on a nationwide survey of more than 1,700 young adults, researchers found that individuals who were the heaviest users of social media were two to three times more likely to feel socially isolated than those who used little to no social media [1]. And that’s a concern to those of us in the medical field: previous research has linked social isolation to worsening physical and mental health, and even an increased risk of death [2,3]. In fact, some experts have gone so far as to label loneliness a major public health concern.


Creative Minds: Do Celebrity Endorsements Influence Teens’ Health?

Marie Bragg is a first-generation American, raised by a mother who immigrated to Florida from Trinidad. She watched her uncle in Florida cope effectively with type 2 diabetes, taking prescription drugs and following doctor-recommended dietary changes. But several of her Trinidadian relatives also had type 2 diabetes, and often sought to manage their diabetes by alternative means—through home remedies and spiritual practices.

This situation prompted Bragg to develop, at an early age, a strong interest in how approaches to health care may differ between cultures. But that wasn’t Bragg’s only interest—her other love was sports, having played on a high school soccer team that earned two state championships in Florida. That made her keenly aware of the sway that celebrity athletes, such as Michael Jordan and Serena Williams, could have on the public, particularly on young people. Today, Bragg combines both of her childhood interests—the influence of celebrities and the power of cultural narratives—in research that she is conducting as an Assistant Professor of Population Health at New York University Langone Medical Center and as a 2015 recipient of an NIH Director’s Early Independence Award.
