Periodic Reporting for period 3 - IMPACT DIABETES B2B (Implementation Action to prevent Diabetes from Bump 2 Baby (IMPACT DIABETES B2B): a low-resource system of care intervention for appropriate gestational weight gain and improved postnatal outcomes)
Reporting period: 2023-01-01 to 2024-06-30
IDB2B’s main objective is to contribute to the early prevention of maternal/child diabetes, overweight/obesity and other chronic health issues (high blood pressure, heart disease, behavioural and learning problems). B2B&Me RCT will enable the collection of important information on: mother and baby health; the project fit within maternity services; its cost; and women's thoughts on the trial. This information is critical to collect and share widely if IDB2B is to be rolled out more widely. We hope the intervention will provide the support that women need at the right time and ultimately deliver improved mother and baby outcomes.
During reporting period (RP) 3, the independent trial monitor (UCPH) completed the monitoring of ethical compliance as all clinical sites (Ireland, UK, Spain, and Australia) closed out the RCT during 2023. The final number of completed RCT participants is 585. Data collection was completed on the NUID UCD secure online platform by early 2024 following the completion of the blood samples analyses. NUID UCD locked the database and completed the data cleaning. Numerous materials were developed to facilitate IDB2B communications, dissemination and exploitation (B2B&Me logo/branding, project website, Twitter, YouTube and LinkedIn accounts, standard slides with key messages/graphics, infographics, language guide, and HCP flyer). The project has continued to raise stakeholder awareness via social media posts, articles, blogs, participant newsletters and conference presentations. During RP3, the IDB2B exploitation plan was updated, and the tools/materials continue to be refined. Two successful implementation forums were held to engage policy and healthcare stakeholders during RP3. All required project documents were delivered to a high standard and all partners were supported with timely deliverables submission and milestone achievement.
● Identify those at highest risk of GDM earlier and support them to better manage their pregnancy
● Support women to improve nutrition and have appropriate GWG
● Enable women in rural and remote settings to access the same care as those women in populated settings
● Reduce GDM-associated risk (e.g. birth complications, stillbirth, maternal morbidity such as hypertensive complications of pre-eclampsia and eclampsia, caesarean section, mortality)
● Reduce maternal obesity risk (e.g. mortality) and associated offspring risks (e.g. macrosomia, intrauterine death, stillbirth)
● Reduce T2D risk
1. IDB2B is unique in integrating evidence-based programmes from existing published interventions into an evidence-based app that can deliver a seamless intervention. This integration is exceptional in the field, builds on the €44.2M global investment in >100 RCTs to date and represents incredible value.
2. The B2B&Me health coaching platform/app delivered focused support to facilitate breastfeeding and health behaviour change, which was lacking in this field. The B2B&Me platform monitored health coach engagement and had the potential to flag declining emotional wellbeing or increasing stress. Health coaches could then preempt these issues and support anticipatory coping resource implementation.
3. The evidence synthesis work from WP1 created a substantial, cutting-edge repository of behaviour change strategies and optimal study designs that have been shared through publication and will continue to be built on with the wider academic communities and health services.
4. High-risk women are the intervention effort focus, and the intervention will have better return on investment than a generic intervention in all pregnant women.
The study will result in 4 key outputs:
● Innovative Healthcare Intervention: the B2B&Me mHealth coaching programme provides coaching for weight management via a smartphone app and real-life health coach
● Implementation Toolkit: information and resources to support B2B&Me implementation and scale up
● Economic model: cost-benefit analysis justification for B2B&Me implementation
● Policy Options: to inform future policy on maternal and early life interventions in the context of GWG and GDM.
The B2B&Me RCT that supports the IDB2B main outputs only finished in October 2023 and the data analysis is ongoing so the key exploitable results are not available yet.
