- Lead Sponsor
- The University of The West Indies
- Brief Summary
The researcher will study a group of pregnant Barbadians with BMI at booking of greater than or equal to 35. All of the women will be given leaflets telling them about healthy diets in pregnancy and how to limit weight gain. Half of the women will be sent to the dietitian for small group classes on diet and how to limit weight gain. The two groups of women will be compared to see which group gains more weight and which group has more complications during the pregnancy.
- Detailed Description
More than 2100 pregnant women per annum deliver their babies at the Queen Elizabeth Hospital, the lone publicly-funded hospital providing secondary and tertiary-level obstetric care in Barbados. Routinely recorded data do not capture whether patients are overweight or obese. Thus, the prevalence of obesity is not known amongst this population. Additionally, these women are not routinely referred for dietician services, and thus the impact of dietician intervention is not known. The aim of this research is to determine whether a dietitian-led intervention could lead to decreased gestational weight gain and less incidence of foetal macrosomia in a sample of Barbadian women, with class II obesity, attending a public antenatal clinic. Prior studies examining gestational weight gain, found no statistically significance between groups when a BMI of 30 was used. It is hoped that by using a group with higher obesity a larger difference will be seen with the intervention. Participants with body mass index greater than 35kg/m\^2 who meet the eligibility criteria will be selected from one of five antenatal clinics at the Queen Elizabeth Hospital on the island of Barbados. They will be randomised to either receive didactic dietary sessions or a standard education tool. Mean weight change will be compared amongst the two groups after delivery to determine if there was a decrease in gestational weight gain amongst the intervention group.

- Primary Outcome Measures
Name Time Method Mean change in gestational weight in kilograms in each arm of the trial From enrolment until delivery Weight at or before delivery minus weight at enrolment
- Secondary Outcome Measures
Name Time Method Incidence of gestational diabetes in each arm of the trial Beyond 20 weeks gestation and prior to delivery Defined using the National Diabetes Data Group (NDDG) criteria, which uses fasting, 1-hour, 2-hour, and 3-hour plasma glucose levels of 5.8mmol/L, 10.6mmol/L, 9.2mmol/L and 8.1mmol/L respectively diagnosed after 20 weeks gestation
Mean neonatal birth weight in grams in each arm of the trial Within one hour of birth Weight of the neonate at birth
Incidence of primary post partum haemorrhage in each arm of the trial Within 24 hours of delivery The loss of 500 milliliters or more of blood from the genital tract within 24 hours of the birth of a baby. Postpartum haemorrhage will be further subclassified as minor (blood loss 500-1000 ml) or major (blood loss more than 1000 ml)27. Major postpartum haemorrhage will also be subdivided into moderate (1001-2000 ml) and severe (more than 2000 ml).
Incidence of low one minute APGAR score in each arm of the trial After one minute of birth Defined as a score less than seven
Incidence of pregnancy induced hypertension in each arm of the trial Beyond 20 weeks gestation and prior to delivery New hypertension presenting after 20 weeks of pregnancy without significant proteinuria
