Contraception use and knowledge related to pregnancy in diabetic women.

Background: Diabetes mellitus prevalence is increasing among women of child-bearing age. Diabetic pregnancy is associated with major maternal and fetal risks, and these can be reduced by preconception care. Pregnancy can be planned using appropriate effective contraception. The objective of this study was to assess diabetic patients' knowledge about pregnancy and to describe their contraceptive use.

Study Design: An observational study was conducted from February to July 2020 at Reims University Hospital, France. Inclusion criteria were: women aged 18 to 40years, with type 1 (T1D) or type 2 diabetes (T2D). Patients filled out a survey about contraceptive use and knowledge regarding diabetic pregnancy and data were completed from medical records.

Results: Eighty-nine T1D and 33 T2D patients were included, with mean ages of 27.9±6.3 and 32.6±4.6years, respectively. Seventy-five percent reported that they had been informed about pregnancy-related risks and 67% about the need to plan pregnancy. The preconception HbA1c target was known by 33% of patients. Appropriate knowledge about pregnancy was greater in T1D patients (65.9%, versus 36.4% in T2D patients; P=0.003). The rate of patients using an effective contraceptive method was 66.4%. Fifteen percent patients for whom contraception was recommended reported having no contraceptive method; 12.5% of contraception users were using a contraindicated method.

Conclusion: A large majority of diabetic women were aware of pregnancy-related risks and the importance of pregnancy planning, but there are still gaps, especially in T2D patients. We need to improve our practices by providing more information and better access to appropriate effective contraception.
