Birth characteristics of women who develop gestational diabetes: population based study

Abstract
We used linked generation data from the medical birth registry of Norway to study all women born in 1967–84 who had given birth between 1988 and 1998. The registry is a compulsory reporting system and files used for analysis are anonymised. Although there were 141 107 women in the cohort, we excluded 2393 who were not singletons.
