| Head circumference | 0.77 a | < 0.01 | 0.14 (− 0.27, 0.55) | 0.05 | 0.503 |
| Congenital heart defects | 0.72 | < 0.01 | 0.34 (− 1.10, 1.78) | 0.03 | 0.639 |

| Otitis media with effusion | 0.72 | < 0.01 | 0.66 (− 0.85, 2.16) | 0.05 | 0.389 |
Sex, age, and a measure of SES were included in Model 1. All results shown give total R2 for Model 2, R2 change from Model 1, unstandardized B (95% CI), standardised beta, and p value for each health phenotype.
AVSD atrioventricular septal defect
a Model 1 included age at physical measurement rather than age at medical history telephone interview
b variance explained by Model 1 smaller than for other comorbidities due to a smaller sample; those with a congenital heart defect other than AVSD were excluded from analysis.
