Multivariable Logistic Regression Models of Aerobic PA and Muscle-Strengthening PA Among California Nurses (n = 454)

	Aerobic PA > 150 minutes/week		Muscle-strengthening PA (>2 days/week)
Characteristics	OR (95% CI)	p	OR (95% CI)	p
Age	1.01 [0.99, 1.03]	.23	0.99 [0.97, 1.00]	.12
Race		.02^*		.26
White	1		1
Non-White	0.61 [0.40, 0.94]		0.78 [0.51, 1.20]
Employment status		.02^*		.29
Not working	1		1
Working	0.48 [0.25, 0.91]		0.69 [0.36, 1.35]
Body mass index (kg/m²)	0.93 [0.89, 0.97]	<.001^**	0.92 [0.88, 0.96]	<.001^**
Musculoskeletal symptom index (Score 0–12)	0.99 [0.93, 1.05]	.69	1.03 [0.97, 1.10]	.35

Note. Race was categorized into White versus African American, Asian, American Indian, Alaskan Native, or mixed. Musculoskeletal symptom index is a composite score for symptoms in the lower back, neck, shoulders, and hands/wrists. One point was assigned for each of the following criteria: (a) the intensity of symptoms was at least moderate, (b) the duration was at least 1 week, and (c) the frequency was at least monthly. PA = physical activity; OR = odds ratio; CI = confidence interval.

p < .05.
