Background: Adverse pregnancy outcomes are more common in women with hyperglycaemia. Many women have suboptimal uptake of HbA1c testing postdelivery. Aims: To compare pregnancy outcomes among multi‐ethnic women with different degrees of hyperglycaemia during pregnancy, and their association with postnatal HbA1c uptake after the introduction of email reminders. Materials and Methods: A retrospective and prospective single‐centre study was conducted in South Auckland in 2639 women with early gestational diabetes mellitus (GDM) (diagnosed < 20 weeks), late GDM (diagnosed ≥ 20 weeks), overt diabetes in pregnancy, or known type 2 diabetes (T2DM) during pregnancy. Automated email reminders were sent to general practitioners to increase postnatal HbA1c screening. Results: HbA1c during pregnancy increased across the late GDM (n = 1425), early GDM (n = 148), overt diabetes (n = 573) and T2DM (n = 493) groups (P < 0.001). Stillbirth was least common in the late GDM group (0, 0.7, 0.5, and 1.9%, respectively, P < 0.001), as were caesarean delivery (32.7, 45.1, 39.4, and 53.5%, respectively, P < 0.001), large for gestational age (LGA) (14.7, 18.2, 22.3, and 30.5%, respectively, P < 0.001), small for gestational age (8.8, 16.7, 11.0, and 11.1%, respectively, P = 0.02), and preeclampsia/eclampsia (7.7, 9.2, 13.0, and 14.8%, respectively, P < 0.001). LGA and preeclampsia/eclampsia were more common among Pacific and Māori women than European women (LGA, 30.1, 22.7, 10.3%, respectively, P < 0.001; preeclampsia/eclampsia, 13.5, 14.0, and 8.1%, respectively, P < 0.001). Postpartum HbA1c screening increased among women with GDM/overt diabetes after the introduction of the reminder emails (39.6% vs 34.0%, P = 0.03). Conclusions: Women with late GDM are least likely to experience adverse outcomes. Email reminders to improve postpartum HbA1c screening warrant further investigation. [ABSTRACT FROM AUTHOR]

Background Antepartum haemorrhage of unknown origin ( APHUO) is associated with preterm birth and perinatal mortality. Aim To determine whether smoking beyond the first trimester of pregnancy was an independent risk factor for APHUO. Methods Rates of APHUO were compared between non-smokers and smokers, and non-smokers and ceased smokers. Participants were healthy nulliparous women recruited to the Screening for Pregnancy Endpoints ( SCOPE) prospective cohort study in New Zealand, Australia, Ireland and United Kingdom. Logistic regression was used to compare adjusted odds ratio, 95% confidence intervals ( OR, 95% CI) of APHUO between continued smokers and non-smokers, adjusting for possible confounders. Results Of the 3513 participants, 77.9% ( n = 2737) were non-smokers, 10.6% ( n = 371) ceased in the first trimester and 11.5% ( n = 405) continued smoking beyond the first trimester. APHUO rates were higher in smokers than non-smokers (7.4%, n = 30 vs 4.5%, n = 122; P = 0.01), but there was no difference between ceased smokers and non-smokers (4.3%, n = 16 vs 4.5%, n = 122; P = 0.90). Smoking was no longer significantly associated with APHUO after adjustment for confounders (adjusted OR = 1.28, 95% CI 0.76-2.14), but vaginal bleeding in early pregnancy (adjusted OR = 2.98, 95% CI 2.12-4.18) and overweight/obesity (adjusted OR = 1.43, 95% CI 1.02-1.99) were independent risk factors. First trimester folic acid use was associated with a reduced risk (adjusted OR = 0.44, 95% CI 0.25-0.77). Conclusion Smoking is not an independent risk factor for APHUO after adjustment for confounders, but other risk and protective factors have been identified. [ABSTRACT FROM AUTHOR]
