title: [Twin birth weight discordance and risk of preterm birth].
abstract: Our purpose was to determine whether birth weight discordance is a risk factor for preterm birth of twins. Maternally linked 1970-2000 Kutno Hospital birth certificates were used to analyze gestations resulting in live twins. The degree of discordance correlated strongly with risk for live preterm birth but only for discordances > 20%. Twin birth weight discordance has demonstrated to be a risk factor for preterm birth. The effect was found particularly with discordance > 30%.
