Note: ANCOVA = analysis of covariance, heiQ = Health Education Impact Questionnaire, SD = standard deviation.

*Mean difference = mean score at 3 mo - mean score at baseline.

†Mean difference = adjusted mean after 3 mo (intervention) - adjusted mean after 3 mo (control).

‡ANCOVA was used to compare scores after 3 mo, adjusted for baseline.
