Trampoline Park Injury Trends.

Area of Science:

• Public Health
• Injury Prevention
• Epidemiology

Background:

• Trampoline parks are a significant source of childhood injuries, necessitating effective prevention strategies.
• Lack of exposure data hinders accurate estimation of at-risk populations for trampoline park injuries.
• This study addresses the need for data on trampoline park injury incidence and trends.

Purpose of the Study:

• To measure trampoline park injury incidence using industry data.
• To analyze time trends in trampoline park injuries.
• To provide data for enhancing injury prevention initiatives.

Main Methods:

• Retrospective analysis of injuries and exposure data from 18 trampoline parks (2017-2019).
• Exposure calculated from ticket sales (jumper hours).
• Incidence measured using marginalized 0-inflated Poisson modeling; trends analyzed with Joinpoint regression.

Main Results:

• 13,256 injuries reported over 8,387,178 jumper hours.
• Overall injury rate: 1.14 per 1000 jumper hours; highest for high-performance and foam pit jumping.
• Significant injury rate: 0.11 per 1000 jumper hours; highest for high-performance and parkour.
• Injury rates showed a monthly decrease of 0.72% over the study period.

Conclusions:

• Trampoline park injuries occur, sometimes seriously, but are uncommon in safety-compliant parks.
• Exposure-adjusted injury rates are declining, indicating positive trends in prevention.
• Further efforts are needed to reduce severe injuries and enhance overall safety in trampoline parks.
