^aBMI success defined as maintaining normal BMI at baseline, decreasing overweight BMI at baseline to normal BMI, or decreasing obese BMI at baseline to overweight or normal BMI
^bAnalysis includes 1184 participants with complete baseline data (694 BALANCE, 490 control). Multiple imputation conducted for missing data using ten imputed datasets
^cRestricted to participants with valid (non-missing) outcome measures (Post-test: 477 BALANCE, 337 control; Follow-up: 366 BALANCE, 240 control)
^dOdds ratio (OR) and 95 % confidence interval (95 % CI) adjusted for age, race, baseline BMI, and baseline postpartum status
