Rationale: The overall aim of this research is to develop (Phase 1) and test (Phase 2) the feasibility of the Bump2be Internet intervention for use with Diabetes mellitus type 1 (T1DM) women who are either TP or PP to help them effectively detect and reduce occurrences of extreme BG levels. Phase 1 of this research was submitted and approved by the Institutional Review Board (HSR# 16668) in 2013 and has been completed. The Bump2be intervention is based on BGATHome (Blood Glucose Awareness Training at Home), which is an automated, tailored, Internet delivered, psycho-educational intervention for T1DM patients. BGATHome is based on theories of self-regulation of health behavior, and the training focuses on patients' learning how to use both internal cues (e.g., physical and mood changes) and external cues (e.g., insulin and food action) to improve their BG awareness. It has proven successful in improving patients' glycemic control as well as their abilities to detect, anticipate, avoid, and treat extremes BG levels. Investigators have historically excluded T1DM women who were either pregnant or planning pregnancy from BGAT-related studies given their unique clinical needs and glycemic targets. The investigators now propose to evaluate the feasibility and effectiveness of Bump2be in women with T1DM who are either TP or PP to help them better regulate their BG levels and to meet the diabetes-related clinical targets for and during pregnancy. This protocol covers Phase 2 of this project.
