Variables significantly associated with more weight loss from entry into phase I to end of study

Model 1. Variables associated with more weight loss, entry into phase I to end of study (model includes phase I weight loss)
		Entry							Phase I
	Model R2 (P value)	Older age	Lower entry weight	Less social support	Not taking BP meds	Taking lipid meds	Higher HEI score	Lower depression score	More phase I weight loss

Model 2. Variables associated with more weight loss, from entry into phase I to end of study (model includes behavior change from entry into phase I to end of study)
		Entry					Change from entry to end of study

All models are based on backward selection and include the following variables measured at entry into phase I: age, weight, education, income, smoking status, treatment for hypertension and/or dyslipidemia, quality of life, social support for diet and exercise, perceived stress, depression, weight loss history, perceived discrepancy between current weight and desired weight, and participant’s expected weight loss during phase I. Model 1 also includes phase I weight change. Model 2 includes change in physical activity (PA) and change in Healthy Eating Index (HEI) over the entire course of the study (i.e., from phase I entry to 30 months post-randomization), but does not include phase I weight change.

Variables retained in model if P ≤ 0.10 but included in table only if P value in final model ≤0.05 (marked with √).

Coefficients based on 5-imputation datasets.
