This study aimed to determine the overall and gestation\u2010specific risk of neonatal morbidity by maternal region of birth, after adjustment for maternal, infant and birth characteristics, for women giving birth in New South Wales, Australia, from 2003 to 2016.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>The study utilized a retrospective cohort study design using linked births, hospital and deaths data. Modified Poisson regression was used to determine risk with 95% confidence intervals (95% CI) of neonatal morbidity by maternal region of birth, overall and at each gestational age, compared with Australian or New Zealand\u2010born women giving birth at 39\u00a0weeks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 1\u00a0074\u00a0930 live singleton births \u226532\u00a0weeks\u2019 gestation that met the study inclusion criteria, and 44\u00a0394 of these were classified as morbid, giving a neonatal morbidity rate of 4.13 per 100 live births. The gestational age\u2010specific neonatal morbidity rate declined from 32\u00a0weeks\u2019 gestation, reaching a minimum at 39\u00a0weeks in all maternal regions of birth. The unadjusted neonatal morbidity rate was highest in South Asian\u2010born women at most gestations. Adjusted rates of neonatal morbidity between 32 and 44\u00a0weeks were significantly lower for babies born to East (adjusted relative risk [aRR] 0.65, 95% CI 0.62\u20100.68), South\u2010east (aRR 0.76, 95% CI 0.73\u20100.79) and West Asian\u2010born (aRR 0.93, 95% CI 0.88\u20100.98) mothers, and higher for babies of Oceanian\u2010born (aRR 1.11, 95% CI 1.04\u20101.18) mothers, compared with Australian or New Zealand\u2010born mothers. Babies of African, Oceanian, South Asian and West Asian\u2010born women had a lower adjusted risk of neonatal morbidity than Australian or New Zealand\u2010born women until 37 or 38\u00a0weeks\u2019
