Reducing physical activity disparities between genders could save billions

This study, led by researchers from the Center for Advanced Technology and Communication in Health (CATCH) at the CUNY Graduate School of Public Health and Health Policy (CUNY SPH) and the National Institute on Minority Health and Health Disparities (NIMHD), contributes to the growing body of evidence suggesting that targeted interventions can have a profound impact on the health of future generations while also alleviating financial burdens on healthcare systems.

Unfortunately, studies also show significant disparities between the physical activity levels of male and female youth. For example, only 15% of female participants in grades nine to 11 as compared to 31% of their male counterparts met aerobic guidelines, as shown by the 2011-2019 Youth Risk Behavior Survey. There are even greater disparities in sports participation. A 2019 study found that 54.1% of female participants as compared to 60.4% of male participants participate in sports.

To simulate what would happen if these disparities were reduced to different degrees, CATCH and NIMHD researchers decided to utilize a computational model of all the youth in the U.S. The computer simulation model represents all the six-to-17-year-olds in the U.S. as virtual agents starting with different ages in the model, and then simulated the daily physical activities of each youth, their growth, the impact of the physical activity on their health, the different chronic medical conditions that could emerge, and the resulting costs over time.

Bruce Y. Lee, MD, MBA, study's senior author and professor of health policy and management at CUNY SPHThis study shows how eliminating sex disparities in physical activity and sports would not only be the fair thing to do, it would also be economically beneficial for society. Eventually efforts to increase physical activity and sport participation for girls and women could end up paying for themselves and more."

"Sports participation disparities among boys and girls can exist due to fewer opportunities for girls to play sports, especially in high school, and less social support. Our study shows that the cost savings of increasing girls' sports participation can justify investing in the changes needed to increase it," says Jessie Heneghan, MCP, co-author and senior analyst at PHICOR.
