Self-Reported Use of Prohibited Substances and Methods Among Athletes of the Brazilian Delegations

Use of prohibited substances and methods (doping) by elite athletes is a complex and multifactorial behavior. Understanding the factors associated with doping behavior is crucial to identifying potential intervention targets to reduce doping among this group. However, there are limited data on the prevalence and correlations of self-reported prohibited substance use among Brazilian Olympic athletes. We present data from a cross-sectional, self-reported online survey. Participants were elite Brazilian athletes who participated in the 2020 Olympic and Paralympic Games. A total of 209 athletes (52.6% females) from both Brazilian delegations were surveyed. The self-reported doping use of prohibited substances or methods was found to be 7.2%. Receiving a recommendation from a medical doctor, even knowing that the substance is prohibited, was associated with an increased risk of self-reported doping use (OR = 17.474; 95% CI = 4.664-65.470, P < 0.001). Nearly 1 in 10 athletes reported use in their careers. Medical recommendation to use substances was the only factor associated with an increased risk of doping among elite athletes.
