Demographics of Women With Type 1, Type 2 and Gestational Diabetes Attending a Diabetes and Pregnancy Clinic in 2000-2002, 2010-2012 and 2014-2016

Pregnancies complicated by diabetes are increasingly frequent. The Endocrine and Pregnancy Clinic [EPC] at St Joseph’s Health Care London is the stable, local provider of all outpatient pregnancy diabetes care, thereby providing an opportunity to document patient characteristics with time. Methods EPC charts were reviewed for: 2000-2002; 2010-2012; 2014-2016 documenting DM type (T1DM, T2DM, GDM); age; weight; year/week of DM diagnosis; medication/pump use; A1C. Continuous results were analyzed by one-way analysis of variance (ANOVA); non-parametric results were analyzed by Chi-square testing; p Results Total EPC DM women were: 2000-2002: 408; 2010-2012: 571; 2014-2016: 813. GDM women represented 72.8% of EPC patients in 2001-2002 and 88.4% in 2014-2016. Weights and oral medication use increased with time for women with GDM, while insulin use decreased. Pump use in women with T1DM increased by 2010-2012 and 2014-2016 while A1C decreased significantly comparing first to last visits within each time interval. Numbers of women with T2DM increased significantly but weight at first clinic visit was lower over time, while A1C decreased significantly when comparing first to last visits within each time interval. Discussion/Conclusions EPC volumes doubled from 2000 to 2016 with no increase in background deliveries, predominantly due to increased numbers of women GDM, along with a small increase in women with T2DM. These findings may help inform decisions around health care planning and resource allocation.
