Clinical Trial 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.

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.

Intervention

Behavioral:
• Didactic dietary sessions
Three one-hour online nutrition group classes will be scheduled at 17, 21 and 29 weeks gestation (± 1 week). Nutrient dense foods and beverages and limiting the intake of added sugars, sodium and saturated fat will be encouraged, as well as reading the nutrition facts label, individual goal setting and self-monitoring. Physician recommended physical activity will be encouraged. Food and beverage intake data will be measured by 24-hour dietary recalls collected on three non-consecutive days. Data will be collected by telephone interview by a registered dietitian or dietary technician on four separate occasions: 16, 20 and 28 weeks gestation (± 1 week) and 36 weeks of gestation. Details on portions consumed will be estimated using standard measuring cups and household utensils. Nutrient intake will be generated using Vision Software Nutrient Analysis Software and the United States Department of Agriculture Food Composition Database, Food Data Central.
• Education Tool
The standard patient education tool will take the form of a leaflet which will include 1. A definition of body mass index 2. A list of measures to be taken to limit weight gain in pregnancy. 3. A description of the major nutrients required in pregnancy (folate, iron, calcium, vitamin D and protein). and 4.A description of the six food groups with recommendations for the number of servings per day.
