Note. BMI = body mass index; HbA1c = health behaviors and child glycated hemoglobin; QOL = quality of life.
Estimates come from least square means, evaluated at average baseline value for the outcome. A negative value indicates a decrease from baseline and a positive value indicates an increase from baseline.
Subsequent significant pairwise comparisons (adjusted p < 0.05 using Tukey adjustment): FB versus PO at 24 months (p = .0059).
Subsequent significant pairwise comparisons (across time since no interaction, using Tukey adjustment).
If the three-way interaction was not significant it was removed and the pairwise interactions with the covariate were examined.
Categorical BMI (obese and not obese).Bold and italics indicate p < .05
