Center for Epidemiologic Studies – Depression Scale (CES-D); Perceived Stress Scale - 10 (PSS-10). BMI = body mass index by: normal/underweight (BMI < 25), overweight (BMI 25–29.9) and obese (BMI > 30). Results shown are from multiple logistic regression models with each psychological and side effect variable entered separately into models; point estimates were stable in combined models with all variables entered together. Results are presented as adjusted odds ratios (OR) with 95% confidence intervals (CI) based upon logistic regression. P-values for alpha <0.05 or <0.01 considered significant. Randomization treatment group was included in all models and was highly significant at alpha <0.001.

Point estimates of covariates education and BMI shown are those from the depressed mood model but were stable among all models.
