622Low birthweight prediction is not improved by repeated measures of gestational weight: the BOSHI study

Background Both pre-pregnancy body mass index and total weight gain during pregnancy are known risk factors for perinatal outcomes. However, little is known if repeated measurements of gestational weight gain can be utilized in the prediction of perinatal outcomes. We examined whether repeated measu...

Description
Summary:Background Both pre-pregnancy body mass index and total weight gain during pregnancy are known risk factors for perinatal outcomes. However, little is known if repeated measurements of gestational weight gain can be utilized in the prediction of perinatal outcomes. We examined whether repeated measures of gestational weight improve the prediction of low infant birthweight. Methods Using data from the BOSHI study, we developed prediction models with low infant birthweight (
