The UK Pregnancies Better Eating and Activity Trial (UPBEAT)

This large multi-centre study was funded by the NIHR and led by Professor Lucilla Poston at St Thomas' Hospital. The aims were to develop and evaluate an intervention for pregnant women with obesity to improve maternal and child pregnancy outcomes. Our group was primarily responsible for the psychosocial aspects of the intervention development and evaluation. The primary outcomes in this RCT were maternal gestational diabetes and infant macrosomia. A pilot RCT showed that diet, measured with 24 hour recalls, significantly improved in women receiving the intervention compared to the control group, but physical activity was more difficult to change. However, the RCT did not find significant group differences for the primary outcomes, although there were differences in some of the maternal secondary outcomes (diet, physical activity, gestational weight gain, adiposity measures).
