Outcomes of Pregnancies Affected by Gestational Diabetes and Type 2 Diabetes in a Rural First Nations Obstetrical Program in Northwest Ontario.

OBJECTIVES

In this work, we describe diabetes prevalence and birth outcomes in a primarily First Nations obstetrical population in northwest Ontario.

METHODS

This retrospective, observational study of maternal and neonatal characteristics and birth outcomes was performed at the Sioux Lookout Meno Ya Win Health Centre between April 1, 2012 and March 31, 2017.

RESULTS

The prevalence of pre-existing type 2 diabetes mellitus was 3.7% and gestational diabetes mellitus was 7.9%. Mothers with diabetes, compared to those without diabetes, were, on average, 5 years older and were of greater parity. Average prepregnancy weight was higher, with an increased incidence of hypertension, inductions and caesarean sections. Neonates had increased incidence of macrosomia, hypoglycemia and hyperbilirubinemia. All maternal cohorts had high rates of alcohol, tobacco and illicit opioid use.

CONCLUSIONS

We have identified a high prevalence of diabetes in this First Nations obstetrical population, with associated adverse maternal and neonatal outcomes.
