At six campuses across Texas, The University of Texas Health Science Center at Houston (UTHealth) School of Public Health works to improve the state of public health in Texas every day. Each of our campuses is strategically placed to meet the public health education and research needs of the diverse populations across Texas. UTHealth School of Public Health is the only school of public health in the nation with regional campuses.

The main campus, located in the heart of Houston’s Texas Medical Center, offers students unmatched opportunities for research and employment.  The School of Public Health’s five regional campuses are in Austin, Brownville, Dallas, El Paso and San Antonio. Each campus has its own faculty and research specialties. Students can attend class at any of the six campuses via Interactive Television (ITV).

UTHealth School of Public Health is one of six schools of The University of Texas Health Science Center at Houston (UTHealth), the most comprehensive academic health system in The University of Texas System and the U.S. Gulf Coast region. In addition to the School of Public Health, UTHealth is home to schools of biomedical informatics, biomedical sciences, dentistry, medicine and nursing. It also includes a psychiatric hospital, multiple institutes and centers, a growing network of clinics and outreach programs in education and care throughout the region.

The School of Public Health is accredited by the Council on Education for Public Health (CEPH) and the university is accredited by the Southern Association of Colleges and Schools (SACS).

Research shows teens too low on sleep, activity, and too high on screen time

Only 1 in 20 U.S. adolescents is meeting national recommendations for sleeping, physical activity, and screen time, according to new research by The University of Texas Health Science Center at Houston (UTHealth).

The study, published today in JAMA Pediatrics, also revealed differences in the findings between females and males, with just 3 percent of girls reaching all three guideline targets, compared to 7 percent of boys.

“There is plenty of evidence to show how teenagers aren’t getting enough physical activity, or sufficient sleep, or keeping their screen time in check. But this is the first time these three factors, which have a crucial bearing on a child’s health, have been analyzed together among a nationally representative sample of U.S. adolescents,” said first author Gregory Knell, PhD, a postdoctoral research fellow at UTHealth School of Public Health in Dallas. “The results are a wake-up call for everyone who wants to make sure our children have a healthy future.”

It is recommended by the National Sleep Foundation that children ages 14-18 sleep eight to 10 hours a night. The U.S. Department of Health and Human Services recommends at least an hour of moderate or vigorous physical activity daily, and limiting screen time to less than two hours.

The research involved nearly 60,000 American high school students, using data from the 2011-2017 Youth Risk Behavior Surveillance Survey.

“By far the most startling finding was how few adolescents across the board are meeting all three recommendations,” Knell said. “I expected the percentage of adolescents meeting all three requirements concurrently to be low, but not this low. The combined effect on children’s overall health could be considerable in terms of their physical health, emotional well-being, and academic performance.”

The study further examined other attributes of the child – age, race or ethnicity, weight, and mental health – and how these were linked to sleep, physical activity, and screen time.

Findings showed older teenagers, non-Hispanic black children, Asian children, those classified as obese, and those who showed signs of depression were the least likely to meet all recommendations when compared to their counterparts.

The paper calls for more research to better understand the relationship among sleep, physical activity, and screen time by exploring the effect these behaviors have on each other and their wider implications over time. It also urged doctors to ask patients about these behaviors, provide them and their parents with advice, and make any necessary specialist referrals.

“These findings are only scratching the surface and demonstrate a need to learn more about the role parenting style and home environment may play in increasing or curtailing these behaviors,” Knell said. “Although the study confirms and further reveals how few children are leading optimal lifestyles, it also raises many questions about what can be done to reverse that trend and improve their health.”

UTHealth co-authors were Casey Durand, PhD; Harold Kohl, PhD; and Kelley Pettee Gabriel, PhD, who was senior author. Ivan Wu, PhD, of The University of Texas MD Anderson Cancer Center was also a co-author.
