The NPID Audit 2015 report, includes data on women with diabetes who had pregnancies in England, Wales and the Isle of Man between 1 January 2015 and 31 December 2015.
The report concludes only 16% of women with type 1 diabetes and 38% of women with type 2 diabetes had first trimester HbA1c <48 mmol/mol (6.5%). Worryingly, only 46% of women with type 1 diabetes and 23% of women with type 2 diabetes were taking the higher recommended folic acid dose for women with diabetes of 5 mg prior to pregnancy. In addition, only a third of women with type 2 diabetes and half of women with type 1 diabetes had contact with an antenatal diabetes team in the first 8 weeks of pregnancy.
Among women with diabetes, the stillbirth rate is still higher than in the general population (4.7 per 1000 live and stillbirths), however, it has reduced significantly since the 2002–03 CEMACH study for women with type 1 and type 2 diabetes (10.7 and 10.5 per 1000 respectively). Preterm delivery, babies large for gestational age and admission to a neonatal unit were more common for women who had HbA1c above 48 mmol/mol (6.5%) at 24 weeks or more.
