The goal of this clinical trial is to evaluate the effects of a couple-based collaborative lifestyle intervention among women with a history of gestational diabetes. The main questions it aims to answer are:
Does the intervention improve body mass index and 2-hour plasma glucose after an oral glucose tolerance test? Does the intervention improve health behaviors, psychological well-being, self-efficacy, couple functioning, and life satisfaction?
Researchers will compare a couple-based collaborative lifestyle intervention with a woman-only lifestyle intervention to determine whether adding spousal collaboration and support leads to greater improvements.
Participants will:
Receive healthy lifestyle education posts for 3 months. In the couple-based group, also receive instant messages on behavioral promotion and couple collaboration and support videos.
20 to 40 years of age.
Diagnosed with gestational diabetes mellitus during the most recent pregnancy.
