Note: Effects significant at p < .05 (χ2 > 3.84 for one df tests) are bolded. Adjusted Incident risk ratio (IRR) gives the proportional change in each outcome as a function of one unit change in the predictor controlling for the other predictors in the model. 95% Confidence intervals are presented in parentheses. The IRR’s are assessed relative to the following reference groups: female, Caucasian non-Hispanic, and Army, which each have an IRR = 1 by definition.
