The influence of exercise and BMI on injuries and illnesses in overweight and obese individuals: a randomized control trial

Table 5 Beta coefficients and standard errors for time to first 1) injury/illness or 2) lower body musculoskeletal injury.

	Self-reported Outcome (time in months)
Independent variables in censored linear regression models	Any injury/illness attributed to exercise		Lower body musculoskeletal injury attributed to exercise
	β ± SE	p-value	β ± SE	p-value
Exercise Intervention ^a		0.41		0.51
Control	Reference		Reference
150 minutes/week	0.9 (2.5)		0.4 (2.9)
200 minutes/week	-2.3 (2.0)		-2.6 (2.3)
300 minutes/week	-1.8 (2.3)		-2.3 (2.6)
BMI (kg/m²) at baseline ^{b, c}	-0.51 (0.18)	0.005	-0.39 (0.21)	0.06

^a The β (SE) for the exercise (150, 200 or 300 minutes/week) versus the control group was -1.5 (1.9), p = 0.41 for any injury/illness attributed to exercise and -1.9 (2.2), p = 0.37 for lower body musculoskeletal injury attributed to exercise.
^b The β (SE) for obese (≥ 30 kg/m²) versus overweight (25-29.9 kg/m²) participants at baseline was -2.6 (1.5), p = 0.08 for any injury/illness attributed to exercise and -2.4 (1.7), p = 0.16 for lower body musculoskeletal injury attributed to exercise.
