About this study

Official title: Lifestyle Interventions to Prevent Postpartum Type II Diabetes Mellitus in Asian Women With a History of Gestational Diabetes Mellitus

This study aims to test the following hypotheses in a randomized controlled trial of post-partum women with a history of gestational diabetes mellitus (GDM) that will be followed up for up to 4 years:

  1. Post-partum pregnancy is ideal for behavioural modification and adopting a healthy lifestyle. Using the continous glucose monitoring (CGM) sensor and an exercise tracker will promote self-motivation and awareness by positive reinforcement and behavioural changes to improve diet, control body weight and increase physical activity in this group of post-partum women who are at high risk for developing Type II Diabetes.
  2. The use of the continous glycose monitoring (CGM) sensor and exercise tracker will motivate women to modify their dietary food intake and physical activity over time, reducing their cardiovascular risk factors for developing metabolic syndrome by lowering their baseline blood pressure, BMI, reducing their waist circumference and body fat mass, glycaemic levels and fasting lipids within the targeted healthy range.
  3. There will be an increase in the quality adjusted life years (QALYs) gained based on improvements in HbA1C and other proximal outcomes at the end of the trial.
Read the detailed description

The increased incidence of gestational diabetes mellitus (GDM) resulting from increased insulin resistance has become a major health concern. GDM affects 5-10% of pregnant women in Europe, while the prevalence in Asian populations is significantly higher at approximately 15-20%. There is a need for early postpartum intervention strategies beginning soon after birth, but yet there are limited of such intervention studies conducted in Asia.

This is a randomized controlled trial and hospital-based study. A total of 300 post-partum women who attended KK Women's and Children's Hospital (KKH) for antenatal consultation and were diagnosed with GDM using International association of diabetes and pregnancy study groups (IADPSG) guidelines at KKH, with a BMI range from 20-40, and physically fit to participate in moderate intensity walking will be approached for prospective recruitment. These subjects will be followed-up to determine if they will have normal oral glucose tolerance test (OGTT) results at 6 weeks postpartum. If all the inclusion criteria is met, these women will be recruited into the study.

The recruited women will be randomly allocated to the intervention or control group. Those placed in the intervention group, which will also be known as the Wearable Care Group, will receive both a continous glucose monitoring (CGM) and an exercise tracker which will be a FitBit watch. Those placed in the control group, which will also be known as the Scheduled Care Group will receive standard medical care.

Participants randomized to both the control (Scheduled Care Group) and the intervention group (Wearable Care Group) will be followed up in the specialist outpatient clinics with a total of 7 visits for up to 4 years. Various testing will be carried out at relevant time points.

Data will be collected through questionnaires and clinical measurements. The questionnaires include socio-economic factors, a quality of life questionnaire, maternal diet, medical histories, lifestyle factors, health status, and home environment. Bio-physical measurements will be obtained from anthropometric measurements of participants, human biological materials such as blood, are collected from the participants at their follow-up time points with the I-HIPS study upon their consent.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Wearable Care GroupDevice

    Continous glucose monitoring sensor: Study participants wear the sensor on the back of either right or left upper arm for up to 14 days. Glucose levels will be recorded from the interstitial fluid every 15 minutes using intermittent/ flash glucose scanning.

    Exercise tracker: A FitBit watch will be given to the participants for use to track physical activity levels.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 6 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinically diagnosed Type II Diabetes Mellitus (time frame: At 6 months (23-26 weeks) from baseline visit). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05081037, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
