teens

Stressed by schoolwork

Just ask any parent or teacher, most of today’s teens and pre-teens don’t seem to get enough sleep. And what sleep they do get is often poor quality—no great surprise, given that smartphones and other electronic devices are usually never far from their reach. Now, an NIH-funded team has uncovered the strongest evidence yet that this lack of quality sleep may be setting our kids up for some serious health issues later in life.

The team’s study of more than 800 adolescents, ages 11 through 13, confirmed that many are getting an insufficient amount of undisturbed, restful sleep each night. While earlier studies had found a link between sleep duration and obesity [1], the new work shows that a wide range of other cardiovascular risk factors are affected by both too little sleep and poor sleep quality [2]. When compared to well-rested kids, sleep-deprived youth were found to have higher blood pressure, bigger waistlines, and lower levels of high density lipoprotein (HDL) cholesterol, which is associated with lower risk of cardiovascular disease.

What was Toben Nelson, a University of Minnesota epidemiologist who studies the health risks of alcohol abuse and obesity, doing this summer lugging around a heavy equipment bag after work? Giving back to his community. Nelson volunteered as a coach for the Roseville Raiders, a 13-year-old-and-under traveling baseball team that just wrapped up its season by winning the prestigious Gopher State Tournament of Champions in their age group.

In the fall, Nelson will gear up for hoops as the volunteer president of the Roseville Youth Basketball Association, which provides an opportunity for kids in this Minneapolis-St. Paul suburb to take part in organized sports. Nelson says volunteering grounds him as a scientist. It reminds him every single day that his NIH-supported research back at the office affects real lives and benefits real communities like his own.

Marie Bragg

Marie Bragg

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.

First-term finals are nearly upon us and sadly a disturbing percentage of high school seniors are abusing stimulants Adderall (dextroamphetamine) and Ritalin (methylphenidate), which are prescribed for Attention Deficit Hyperactivity Disorder (ADHD). These drugs increase alertness, attention, and energy the same way cocaine does—by boosting the amount of the neurotransmitter dopamine.

Even though these drugs are legal, they’re quite dangerous if not used properly. Taking high doses can cause irregular heartbeat, heart failure, or seizures. High doses of these stimulants can lead to hostility or feelings of paranoia. So, rather than popping pills, it’s a lot safer—and smarter—to boost your grades the old-school way: by studying.

Drinking the occasional sugar-sweetened beverage, be it soda, an energy drink, sweetened water, or fruit punch, isn’t going to make you fat. But it’s now clear that many children and adults are at risk for gaining weight if they consume too much of these products.

An illustration showing that 10 spoonfuls of sugar can be found in a 12oz can of soda, 13 spoonfuls of sugar can be found in a 16oz cup of soda and 26 spoonfuls of sugar can be found in 32oz bottle of soda.I want to share new research from three recent papers in the New England Journal of Medicine (NEJM) because, together, they provide some of the most compelling evidence of the role of sugary drinks in childhood obesity, which affects nearly one-fifth of young people between the ages of 6 and 19.

In the first study [1], researchers randomly assigned 641 normal-weight school children between the ages of 4 and 12 to one of two groups. The first group received an 8 oz sugary drink each day; the second received the artificially sweetened version. After 18 months, it was clear that the kids consuming the sugary drink had gained about 2.25 pounds more weight, compared with the kids drinking the zero calorie drinks. They also packed on more fat.
