75% of teens aren’t getting recommended daily exercise
Three out of every four teens aren’t getting enough exercise, and this lack is even more pronounced among female students.
But new research from the University of Georgia suggests improving a school’s climate can increase physical activity among adolescents.
School environments play a critical role in helping children develop healthy behaviors, like creating healthy eating habits, said lead study author Janani R. Thapa. And the same goes for physical activity.
“The length of recess, physical facilities and social environments at schools have been found to affect physical activity among students,” said Thapa, an associate professor of health policy and management at UGA’s College of Public Health.
The state of Georgia has implemented policies and programs to boost physical activity in K-12 schools. Thapa has been one of the lead evaluators of these programs.
“Over time, the state has observed declining levels of physical activity among all adolescents, but the rate is higher among female middle and high school students,” she said.
Thapa suspected that school climate could play an important role in determining how comfortable students feel participating in school sports or other physical activity. School climate includes factors such as social support, safety and bullying.
“We do not know much about the role of school climate on physical activity,” said Thapa. “There must have been barriers that were faced by certain groups of students. Hence, we wanted to investigate the difference by gender.”
Using data from a statewide survey of over 360,000 Georgia high school students that included questions about physical activity levels and school climate, Thapa and her co-authors were able to test that relationship.
The data included eight characteristics of climate: school connectedness, peer social support, adult social support, cultural acceptance, physical environment, school safety, peer victimization (bullying) and school support environment.
Overall, female students reported less physical activity than their male counterparts, only 35% were active compared to 57% of males. And physical activity declined steadily from ninth grade to 12th grade for both genders.
However, students of both genders were more physically active when school climate was perceived to be positive across most measures.
One thing that stood out was the influence of bullying. Female students who reported being bullied were more likely to be physically active, while male students who reported being bullied were less likely to be physically active.
Bullying was the only measure of school climate that differed for male and female students. This disparity could be explained, said the authors, by the different norms about exercise and masculine versus feminine ideals.
“For example, female students who are active in sports and physically active may not fit the gender norm and hence may face bullying,” said Thapa.
These findings suggest that K-12 schools that want to promote participation in physical activity should consider how to improve students’ sense of safety at school and bolster peer and adult support of exercise.
