- CTRI/2018/07/014947
- Lead Sponsor
- Department of Biotechnology Newton Fund Global Research Programme
- Brief Summary
The study is a 2x2 factorial, open-labelled, multi-centre randomized controlled trial to be conducted in Vellore, South India and The Gambia, West Africa. “High-risk†pregnant women (n=1,856) aged ≥18 years and less than 16 weeks of gestational age, with at least one risk factor for developing GDM, will be randomized to one of four arms (i) yoghurt (ii) Physical activity (PA) (iii) yoghurt + PA or (iv) standard antenatal care. Randomised women will be followed until 32 weeks of gestation with total active intervention lasting for a minimum of 14 weeks. The primary endpoint is incidence of GDM diagnosed at 26-28 weeks GA using IADPSG criteria or elevated fasting glucose at 32 weeks. A secondary endpoint is fasting plasma glucose concentration at 32 weeks gestation. Other outcomes include maternal blood pressure, gestational weight gain, intrapartum and neonatal outcomes. Analysis will be both by intention to treat and per-protocol. Continuous outcome measurements will be analysed using multiple linear regression and binary variables by logistic regression.
