Table 2. Multilevel logistic regression analysis of the association between mental distress (symptoms of anxiety and depression) and outcomes variables.

	OR	(95% CI)	P value	Effect size
Symptoms of anxiety
Injury	1.75	(1.17 – 2.62)	0.007	Small
Illness	2.64	(1.69 – 4.12)	<0.001	Medium
Sleep hours*	1.64	(0.48 – 0.77)	<0.001	Small
Hours of sports participation*	1.06	(0.91 – 0.98)	0.004	Very small
Perceived exertion	1.03	(0.90 – 1.05)	0.436	Very small
Symptoms of depression
Injury	2.64	(1.87 – 3.73)	<0.001	Medium
Illness	1.98	(1.30 – 3.02)	<0.001	Small
Sleep hours*	1.09	(0.75 – 1.13)	0.414	Very small
Training hours*	1.03	(0.94 – 1.00)	0.030	Very small
Perceived exertion	1.02	(0.96 – 1.09)	0.560	Very small

^*Reversed regression scale, meaning athletes with fewer hours of sleep and training are more likely to experience mental distress.
