Factors Associated with Intended Postpartum OGTT Uptake and Willingness to Receive Preventive Behavior Support to Reduce Type 2 Diabetes Risk Among Women with Gestational Diabetes in Singapore: An Exploratory Study.

Abstract

Aim:To assess and explore the factors affecting willingness to undergo an early postpartum oral glucose tolerance test (OGTT) and receive postpartum lifestyle modification assistance.Methods:An explanatory sequential mixed-method design was used. A prenatal cross-sectional survey questionnaire (n = 216) was given to women diagnosed with GDM in a tertiary health institution in Singapore and followed up with postpartum semi-structured interviews (n = 30). Multivariate logistic regression and thematic analysis were conducted before merging the findings.Results:Despite universal GDM education, fewer than 75% intended to take the OGTT postpartum, and only 63% felt it was very important. The plan to take the OGTT postpartum was positively associated with a prenatal care provider’s specific recommendation. In contrast, Malay women were less likely to take the test. Most women interpreted a care provider’s recommendation as implying standard practice, which encouraged intended and actual compliance with testing after giving birth. The perception of moderate to high T2DM risk in the following decade, and subsidized prenatal care, and plan to take the OGTT postpartum were positively associated with willingness to receive postpartum lifestyle behavior support. A mobile application was the preferred method to receive support.Conclusions:In the early postpartum period, women with a history of GDM were willing to receive measures to reduce T2DM risk, primarily if it was under the supervision and recommendation of a care provider. A carefully designed but simple postpartum lifestyle intervention incorporating these preferences that can be integrated into mainstream diabetes prevention programs is warranted.
