About this study
Official title: Outcomes of Pregnant Barbadian Women With Obesity: A Case Controlled Prospective Study of Didactic Dietary Intervention Compared to a Standard Education Tool
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Didactic dietary sessionsBehavioural
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 ToolBehavioural
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.
| Study group | Role | What they receive |
|---|---|---|
| Didactic Sessions | Experimental | Women will receive online nutrition education by a registered dietitian, in addition to the same standard patient education tool as the other arm. Receives: Behavioral: Didactic dietary sessions; Behavioral: Education Tool |
| Education Tool | Experimental | Women will receive a standard patient education tool in the form of a leaflet. Receives: Behavioral: Education Tool |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean change in gestational weight in kilograms in each arm of the trial
Weight at or before delivery minus weight at enrolment
Measured: From enrolment until delivery
Secondary outcomes (5)
Mean neonatal birth weight in grams in each arm of the trial
Weight of the neonate at birth
Measured: Within one hour of birth
Incidence of pregnancy induced hypertension in each arm of the trial
New hypertension presenting after 20 weeks of pregnancy without significant proteinuria
Measured: Beyond 20 weeks gestation and prior to delivery
Incidence of gestational diabetes in each arm of the trial
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
Measured: Beyond 20 weeks gestation and prior to delivery
Incidence of primary post partum haemorrhage in each arm of the trial
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).
Measured: Within 24 hours of delivery
Incidence of low one minute APGAR score in each arm of the trial
Defined as a score less than seven
Measured: After one minute of birth

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A study testing Didactic dietary sessions and Education Tool in people with Obesity and Gestational Weight Gain, run by The University of The West Indies.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 10 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Tonya C Johnson, MBBS (4366450, obesityinpregnancystudy@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean change in gestational weight in kilograms in each arm of the trial (time frame: From enrolment until delivery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05575414, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
