Genetic influence on birthweight and gestational length determined by studies in offspring of twins
Abstract
Objective To determine the relative importance of genetic effects on birthweight, gestational length and small for gestational age. Design A cohort study, using individual record linkage between the population‐based Swedish Twin and Birth Registers to estimate twin similarities in twins with known zygosity. Population Included were 868 monozygotic and 1141 dizygotic female twin pairs, born in Sweden before 1959, who both delivered single births from 1973–1993. Methods Quantitative genetic methods, offspring birthweight, gestational length and small for gestational age birth in twin sisters. Main outcome measures Twin similarities measured as probandwise concordance rates and intra‐class correlations for birthweight, gestational length and small for gestational age births. Results Concordance rates and intra‐class correlations for birthweight, gestational length and small for gestational age were consistently higher in monozygotic compared with dizygotic twins. Model fitting suggested heritability estimates in the range from 25% to 40%. Conclusions This study suggests genetic effects not only for birthweight and fetal growth, but also for gestational length. The mediation of these genetic effects may partly be due to similarities in maternal antropometric measures, lifestyle and medical complications during pregnancy. The study does not distinguish between fetal and maternal genetic effects.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
