  • The average contribution of risk factors to the explained portion of the gaps in BMI z scores between white and other race and/or ethnicity boys and girls. For example, differences in infant weight gain between white and African American boys accounted for 70.5% (–0.079 of –0.113) of the explained gap in BMI z scores between the 2 groups. CI, confidence interval.
