Brief summary
Up to 75% of reproductive age women are overweight, 40% are considered obese, and the prevalence of gestational diabetes mellitus (GDM) continues to rise, from 6% to 8.3% between 2016 and 2021. Currently understood GDM risk factors, such as advanced maternal age, prior history of GDM, family history of diabetes, and socioeconomic status can only explain up to 50% of cases. Related factors such as body image dissatisfaction, eating behaviors, and daily stress exposure have been linked to blood sugar metabolization, pregnancy outcomes, and the normative physiological changes that occur during pregnancy. These interrelated mechanisms may serve as additional risk factors that could help identify other women at risk of GDM. This project aims to investigate how body image dissatisfaction, eating behaviors, and daily stress exposure are associated with the metabolization of blood sugar during pregnancy. In this study the Strahm Lab will recruit 50 pregnant women to participate in a study assessing blood sugar metabolization as it is related to stress, body image dissatisfaction, and eating behaviors. The study will use continuous glucose monitoring in concert with an ecological momentary assessment protocol to assess these interrelated factors over the course of 10 days between 14 and 28 weeks gestation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Continuous Blood Glucose via Dexcom G7 | 10 days | Participant will wear a Dexcom G7 CGM for 10 days to measure blood glucose levels (mg/dL) |
| Body Image in Pregnancy Scale (BIPS) | 10 days | Participants will complete the full Body Image in Pregnancy Scale (BIPS) once prior to the start of the 10 day CGM/momentary assessment period and once at the end. The full BIPS scale is 36 items. It assesses body image dissatisfaction. Participants rate each item from one (strongly disagree) to five (strongly agree). Generally, lower scores indicate higher body satisfaction, while higher scores indicate higher levels of pregnancy-related body dissatisfaction/stress due to body image. Participants will receive 8 items from the scale to assess preoccupation with physical appearance and sexual attractiveness, prioritization of physical appearance over body functioning, appearance related behavioral avoidance, and dissatisfaction with body parts at least 5 times each day during the 10 day CGM/momentary assessment period. The full BIPS will be completed in REDCap. Momentary assessments will be completed via Real Time Assessment In the Natural Environment (ReTAINE). |
