The impact of injuries on sports-related analgesic use in Danish youth elite athletes: A 4-week prospective cohort study

Investigate the association between injury severity and sports-related analgesic use, and explore the types and reasons for analgesic use in Danish youth elite athletes. 4-week prospective cohort study. 713 youth elite athletes (44 % female) aged 15–20 years provided information on demographics, sports specific questions, and injury severity. We categorized injury severity based on the amount of impact on sports participation: 1) no injury (reference), 2) injury not affecting sports participation, 3) injury causing modifications in sports participation, and 4) injury causing complete absence from sport. Participants were asked weekly over 4 weeks about the number of days with sports-related analgesic use, types, and reasons for use. Mixed-effects regression models were used to assess the association between injury severity and prevalence (yes/no) and frequency (days/week) of analgesic use. Analgesic use at least once during the four weeks was reported by 224 athletes (31 %), with a mean weekly prevalence of 13 %. The odds of analgesic use increased with injury severity compared with the reference group; injury not affecting sports participation: OR 2.6 (95 % CI 1.6–4.2), injury causing modifications in sports participation: OR 3.2 (95 % CI 2.0–5.2), injury causing complete absence from sport: OR 3.6 (95 % CI 1.5-8.7) (test for trend; p =
