Note. *Results of piecewise linear mixed model. All models were adjusted for age at baseline; models testing changes in vegetable intake and physical activity were adjusted for their baseline measures. Significance is set at p < 0.05 and is in bold. About 82% of families/friends in the FAMILY intervention group and 75% in the control group had complete secondary outcome data.
