Figure 4. Baseline Parent/Guardian Marital Status and Girl’s TV Viewing Time as Moderators of Intervention Effects on Body Mass Index.
In the exploratory moderator analysis, the dance and screen time reduction intervention was significantly more effective than health education among those girls with an unmarried parent/guardian and among those who watched more than the mean amount of television at baseline. The figure illustrates the differences between the intervention groups in the mean ± se changes in BMI for the subgroup of girls with an unmarried parent/guardian, girls who watched greater than the mean of baseline television viewing, and girls with both an unmarried parent/guardian and high baseline television watching.
