Scientific titleHealthy Eating and Lifestyle in Pregnancy (HELP): a cluster randomised trial to evaluate the effectiveness of a weight management intervention in pregnancy on weight at 12 months following birth, gestational weight gain and pregnancy and birth outcomes
Study acronymHELP
Study objectivesIs a weight management intervention for obese pregnant women, which targets physical activity and healthy eating, effective in reducing women’s body mass index (BMI) at 12 months from giving birth and at what cost?
Ethics approval(s)Research Ethics Committee for Wales, 15/12/2009, ref: 09/MRE09/58
Health condition(s) or problem(s) studiedObesity
InterventionWomen will be invited to attend a weekly 1.5 hour group run jointly by NHS midwives and 'Slimming World' (SW) consultants. These groups differ from usual SW sessions because in addition to the diet and lifestyle advice there is midwife input and additional exercise advice and monitoring.

Women will be recruited at 12 - 20 weeks gestation and the intervention will run until 6 months post-partum. The treatment period will therefore vary dependent on what stage in pregnancy the woman was recruited and when she gives birth. However, it will be between 43 and 56 weeks (taking into account normal gestation is 37 - 42 weeks).

Those in the control group will receive usual care from their midwife which includes between 7 and 10 antenatal consultations, as well as a leaflet on healthy eating and physical activity in pregnancy.

The follow up is until one year from giving birth for both arms of the trial.
