Reuel A. Stallones Building in the Texas Medical Center in Houston
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 reveals dangerous midlife switch of ditching activity to sit still
HOUSTON – (August 23, 2018) – People are falling into a trap of greater inactivity during middle age, according to new research from The University of Texas Health Science Center at Houston (UTHealth), which calls for its findings to be considered in future national physical activity guidelines.
Thestudy, published today in theAmerican Journal of Epidemiology, is the first time age-related physical activity changes, from inactivity to vigorous exercise, have been examined at such a large scale across midlife. People in the study who were between the ages of 38 and 50 dropped their activity rates over the next decade by an average of a half an hour a day and replaced it with doing something sedentary.
“We know higher intensity physical activity tends to decline with age. But these findings show just how much even gentle forms of activity that are part of daily routines, like casual walking, slip in midlife, which doesn’t bode at all well for future health and should serve as a wake-up call to us all,” said first and corresponding author Kelley Pettee Gabriel, PhD, MS, associate professor of epidemiology, human genetics and environmental sciences at the Michael & Susan Dell Center for Healthy Living at the UTHealth School of Public Health Austin campus.
Investigators were able to draw the conclusions using data from the Coronary Artery Risk Development in Young Adults Study, also known as CARDIA, which started following 5,115 participants between ages 18 to 30 more than 30 years ago, measuring their activity levels with an accelerometer, or activity monitor, that is similar to a pedometer.
These decreases of physical activity over a 10-year period in middle age were observed in both men and women. However, the decline was steepest among black men who typically started being the most active but reduced their activity levels by nearly one hour daily. Black women began as the least active, and continued to have the lowest physical activity levels 10 years later.
“Our next step is to determine what is causing these changes towards a more inactive daily routine. It could be that during midlife people become busy with their jobs and taking care of children and aging parents. Or, they may be experiencing more difficulty moving around because of aching joints, for instance,” Gabriel said. “What’s clear is that these trends are happening at a time when people face increased risk of disease and disability. Yet, compared to older adulthood, they’re also potentially in a better position to introduce more physical activity back into their daily routine, particularly as they retire.”
National guidelines recommend at least two and a half hours of moderate intensity activity per week, or an hour and 15 minutes of vigorous intensity activity per week, or an equivalent combination of moderate and vigorous intensity activity. They also discourage prolonged sedentary time.
Physical activity is advised to help manage conditions including obesity, high blood pressure and type 2 diabetes. There’s also a growing body of evidence demonstrating the health benefits for older adults of undertaking light intensity physical activity, such as going for a gentle stroll or doing household chores. Such evidence led to the 2018 Physical Activity Guidelines Advisory Committee recommendation that additional research is needed for further understanding.
“Given the findings of our study and others, the health consequences of age-related switches from time spent in light intensity physical activity to sedentary pursuits merit serious consideration and could pave the way for future physical activity guidelines to set targets in these important areas,” said Gabriel. “Making relatively small lifestyle changes, and taking advantage of missed opportunities to be physically active could have a crucial bearing on how people are setting themselves up for being more resilient during older adulthood. Simple changes all add up, like walking to the corner coffee shop, parking further away from the store entrance or taking the stairs rather than the escalator.”
Barbara Sternfeld, Ph.D., emeritus research scientist of Kaiser Permanente Northern California, was senior author of the study, which was funded by the National Heart, Lung, and Blood Institute and the National Institute on Aging, both part of the National Institutes of Health.
The vision of UTHealth School of Public Health is to improve the health of the population through prevention, better health outcomes and a trained population health workforce.
