Association between physical activity and mental health variables in participants with SCI.

Variables	Physical Activity Participation			p for Trend
	1st T (n = 33)	2nd T (n = 35)	3rd T (n = 35)
Depression (PHQ-9)	17.03 ± 5.70	14.71 ± 4.79	12.49 ± 4.01 *	<0.001
Anxiety (GAD-7)	13.24 ± 4.78	10.86 ± 3.19 *	9.86 ± 3.15 *	<0.001
Social Support (MSPSS)	51.24 ± 10.17	54.49 ± 11.74	61.37 ± 11.90 * †	<0.001

Values are mean ± SD. Complex sample general linear model analysis adjusted for age, gender, American spinal cord injury association impairment scale and impaired spinal cord levels. P-values in italics indicate a statistical significance of α < 0.05. Abbreviation: T = tertile; PHQ-9 = Patient Heath Questionnaire-9; GAD-7 = Generalized Anxiety Disorder-7. Physical activity was categorized into three tertile group: (1) low PA (1st T), (2) middle PA (2nd T), or (3) highest PA (3rd T); * significantly different from the “1st tertile” group in physical activity. † significantly different from the “2nd tertile” group in physical activity.
