MBRN includes all live births and stillbirths with a gestational age > 16 weeks.
Information about singleton or plural delivery, infant sex, maternal age at delivery, paternal age, infant birth weight, gestational age, in vitro fertilization (IVF), and previous stillbirths was retrieved from the MBRN.
The prevalence of hypospadias in our study is similar to the prevalence in MBRN (0.
For the present analysis we considered as potentially eligible all women with baseline questionnaire and MBRN data for the first pregnancy in which they were enrolled in MoBa [n - 85,910).
Women classified by the MBRN with unspecified diabetes before or during pregnancy were excluded from the analysis of T2DM and GDiM.
The latter analysis was conducted among the subset of women born in 1967 (when the MBRN was established) or later, with available birth weight (88% of 70,539).
Excluding women with nonconfirmed hypertension [reported only in the baseline questionnaire or MBRN (n = 351)] did not materially change the association with hypertension, so they were included in the analyses.
3% were validated against the pregnancy medical records; and among those without a diagnosis of GDM in the MBRN record, none was classified with GDM by the medical records.
