OBJECTIVE—To determine whether women with pregestational diabetes obtained long-term benefits from an intensive diabetes management program during pregnancy.

RESEARCH DESIGN AND METHODS—Women with pregestational diabetes who had attended an intensive diabetes management program in pregnancy between 1991 and 1999 were interviewed regarding diabetes self-management behaviors and current glycemic control. A retrospective chart review was done to obtain information on self-management behaviors at entry to the program and at delivery and compared with the present.

RESULTS—Comparing entry to the program to delivery, all diabetes self-management behaviors improved significantly, including frequency of self-monitoring of blood glucose, frequency of insulin injections, and frequency and complexity of insulin dose adjustment (IDA). HbA_1c (A1C) also improved significantly from entry to delivery (mean 0.073–0.060) (P < 0.0001). Comparing entry to the present, frequency of insulin injections improved significantly (P = 0.0004), frequency of IDA improved significantly (P = 0.004), and complexity of IDA improved significantly (P = 0.0032). However, there was no significant change in frequency of self-monitoring of blood glucose (P = 0.766) from before pregnancy to the present, and A1C significantly worsened by 0.015 (P < 0.0001, 95% CI 0.009–0.021) from entry to the program to the present.

CONCLUSIONS—Women participating in an intensive diabetes management program during pregnancy improve significantly from entry to delivery in diabetes self-management behaviors and glycemic control and, in the long term, retain some of these behaviors and knowledge. However, this is not reflected in an improved A1C level. This may be explained by the loss of contact with the diabetes care team and/or the discontinuation of frequent self-monitoring of blood glucose—a critical behavior necessary for achieving optimal glycemic control.
