Data are presented as percent weight loss mean (SE) based on modified population marginal means, unless otherwise indicated. Models include attendance, income, race/ethnicity (NHW vs. Hispanic and NHB), and race/ethnicity*income. Neither age (P = 0.973), sex (P = 0.675), nor baseline BMI (P = 0.810) were significant predictors and were removed from final models. Boldface type indicates statistical significance in adjusted percent weight loss within racial/ethnic groups by income level (P < 0.05).
Active participants attended ≥4 sessions in months 1–6 but did not complete the program.
Completing participants attended ≥9 and ≥3 sessions in months 1–6 and 7–12, respectively, per CDC guidelines (3).
