Model 1, n = 4435Model 2, n = 1709
Gender: Boy (vs girl)0.79* (0.65–0.95)0.84 (0.55–1.29)
Ancestry: NH Black (vs nonblack)0.60*** (0.47–0.77)0.65 (0.39–1.09)
Medicaid at 2 mo: (vs non-Medicaid at 2 mo)0.64*** (0.51–0.81)0.94 (0.57–1.53)
Weight z score at 14 ± 7 d as birth weight proxy (continuous)16.5*** (11.4–23.7)
  • Odds of group 3 (WFLref_BMIhigh) versus group 2 discordance (WFLhigh_BMIref) at age 2 mo on the basis of sociodemographic factors and weight z score at 14 ± 7 d was assessed by using logistic regression and is shown as OR (95% CI). Covariates were sequentially added to models in order to assess their relative contributions; a blank dash is inserted where covariates are not included in the model.

  • * P < .05, ***P < .001.
