“…Initial univariate and then multivariable analyses were performed with maternal variables chosen a priori (age <20 years, single parent status, alcohol and/or cigarette use during pregnancy, illicit drug use, cocaine use, geographic isolation, population density and median income) because of their previously demonstrated association with adverse neonatal or perinatal outcomes [5,10,11] or their association with diminished perinatal care in Canada [8]. Dependent variables included perinatal outcomes (prenatal care, caesarian section delivery, delivery at planned center and gestational age of newborn), neonatal nutritional outcomes (PN duration >30 and >60 days, and total days of PN) and neonatal clinical outcomes (GPS moderate or high score, duration of hospitalization, days of mechanical ventilation and all-cause mortality).…”
