ABSTRACT
BACKGROUND:
Pacific Islander (PI) women in Australia have an increased risk of gestational diabetes (GDM); however, their perinatal outcomes are poorly understood.AIM:
The aim was to determine the maternal characteristics and perinatal outcomes of PI women with and without GDM compared to Australian/European (AE)-born women.METHODS:
A retrospective analysis of perinatal outcomes of singleton deliveries >20 weeks' gestation between 1 January 2011 and 31 December 2020 was conducted at a tertiary provider (Melbourne, Australia). Antenatal details and birth outcomes were extracted from the Birth Outcome Systems database. t-Tests and χ2, univariate and multivariable logistic regression analyses assessed the relationship between ethnicity and outcomes.RESULTS:
Of 52,795 consecutive births, 24,860 AE women (13.3% with GDM) and 1207 PI-born women (20.1% with GDM) were compared. PI women had significantly greater pre-pregnancy body mass index (BMI) and significantly lower rates of smoking and nulliparity. PI women with GDM had higher rates of pre-eclampsia (P < 0.001), large-for-gestational age (LGA) neonates (P = 0.037) and neonatal hypoglycaemia (P = 0.017) but lower rates of small-for-gestational age neonates (P = 0.034). Neonatal intensive care unit (NICU)/special care nursery requirements did not increase. After having adjusted for covariates, PI women's risk of LGA neonates (adjusted odds ratio (aOR) 1.06, 95% confidence interval (CI) 0.86-1.31) was attenuated; however, risk of pre-eclampsia (aOR 1.49, 95% CI 1.01-2.21) and neonatal hypoglycaemia (aOR 1.40, 95% CI 1.01-1.96) still increased. They were less likely to require a primary caesarean section (aOR 0.86, 95% CI 0.73-0.99).CONCLUSION:
PI women have higher BMI and GDM rates, contributing to an increased likelihood of adverse perinatal outcomes. BMI is a modifiable risk factor that could be addressed prenatally.
