Outcome rates are per 100 births for preterm, SGA, LBW, LGA or HBW, per 1000 total births for stillbirth, per 1000 live births for neonatal death and infant death and per 1000 neonatal survivors for postneonatal death.
p Values in χ2 tests for differences among the three mother tongue groups in northern Quebec and between the two mother tongue groups in southern Quebec.
p Values in χ2 tests for differences among all the five study groups.
HBW, high birth weight (>4000 g); LBW, low birth weight (<2500 g); LGA, large-for-gestational-age (>90th percentile); SGA, small-for-gestational-age (<10th percentile).
