[Liveborn birth-weight of single and uncomplicated pregnancies between 28 and 42 weeks of gestation from Burgundy perinatal network].
OBJECTIVE
To build a reference chart for birth weight according to gestational age based on a newborn population from single uncomplicated pregnancies.


METHODS
We have used data from the Burgundy perinatal network for the years 2000 to 2005. We can exclude, with a validate linkage procedure of all mother-newborn couples, the whole of newborns from pregnancies complicated by mellitus diabetes or pre eclampsia. After statistical validation, the birth weights were modelled and graphically represented.


RESULTS
We have used 105,665 data from the "healthy" sample to construct a birth weight distribution according to gestational age at 28 to 42 weeks'. Results are also represented adjusted for sex.


CONCLUSIONS
We present an original birth weight distribution according to gestational age from a recent French population sample. Exclusion of maternal conditions which may affect fetal growth modify the data distribution, mainly for low birth weights and premature deliveries. Used in clinical practice, it could lead to better identify newborns with increased risk of postnatal complications.
