| Δ in mean BMI z-score in early adolescence | |||
|---|---|---|---|
| Maintain at or below 0.5 servings/day vs. above during pregnancy and early childhood | At or below 0.5 servings/day through pregnancy, fixing range of early childhood consumption | At or below 0.5 servings/day through early childhood, fixing range of pregnancy consumption | |
| IP weighted estimate1 (primary analysis) | −0.94 (−1.52, −0.08) | −0.05 (−0.34, 0.23) | −0.89 (−1.46, −0.11) |
| Standard Regression, adjusting for baseline covariates2 | −0.41 (−0.86, 0.03) | 0.03 (−0.19, 0.25) | −0.44 (−0.88, −0.01) |

Adjusting for maternal BMI (<25, 25–29, ≥30 kg/m2), college graduate (yes, no), maternal smoking during pregnancy (yes, no), white race/ethnicity (yes, no), annual household income (>$70,000, ≤$70,000), and paternal BMI (<25, 25–29, ≥30 kg/m2).
