Benjamin N. Breyer MD, MAS, FACS Associate Professor in Residence Department of Urology University of California, San Francisco Chief of Urology, San Francisco General Hospital Director, UCSF Male Genitourinary Reconstruction and Trauma Surgery Fellowship MedicalResearch.com Interview with: Benjamin N. Breyer MD, MAS, FACS Associate Professor in Residence Department of Urology University of California, San Francisco Chief of Urology, San Francisco General Hospital Director, UCSF Male Genitourinary Reconstruction and Trauma Surgery Fellowship   Medical Research: What is the background for this study? What are the main findings? Dr. Breyer: Our group has studied genitourinary-specific injuries associated with bicycles using a national surveillance injury database called NEISS (National Electronic Injury Surveillance System), that monitors injuries associated with specific products.  In the current study, we examined trends in all bicycle-related injuries from  1997 to 2013.  We found an increase in bicycle-related injuries over the study period, even after adjusting for growth in the US population.  Even more concerning, we found the percentage of bicycle-related injuries resulting in admission increased 120%, suggesting the injuries sustained while cycling are becoming more severe.  These trends appear to be driven by a substantial rise in both injuries and admissions in individuals over 45 years of age, which likely reflects a change in the demographic of cyclists in the US - multiple studies have shown an increase in the cycling participation of adults over the age of 45. Bicycles are no longer children's toys - they are increasingly being used by adults as a means of transportation and physical activity. The rise in cycling in adults over the age 45 appears to be driving both the increase in injuries and admissions, suggesting that older individuals are at increased risk for sustaining severe injury while cycling.
