Participants were categorized into four groups according to their risk of being addicted to exercise and their injury status. Analyses of two psychological distress outcomes are presented: Depression and Emotional stress. The reference risks for the exercisers at low risk of addiction and with no injuries were 4.5% [2.6%; 6.4%] for depression; and 20.0% [16.3%; 23.7%] for emotional distress. CI = confidence interval. Measure of association is prevalence proportion difference (PPD), which is interpreted as percentage points. The test for no difference between the two injury strata revealed a non-significant difference in PPD across strata of 7.5% [−10.5%; 25.5%], p = 0.41. Similarly, no difference was observed for emotional stress across strata of injury = 1.2% [−22.2%; 24.8%], p = 0.91.
