About this study
Official title: Pilot Feasibility of Dietary Heat-Stabilized Rice Bran Supplementation for Diarrheal Disease Prevention in Nicaraguan Children
The purpose is to assess feasibility of rice bran consumption in weaning children and collect pilot data on gut microbiome and metabolome modulation with rice bran intake for diarrheal prevention.
Read the detailed description
Rice bran is a globally accessible, underutilized food ingredient with an array of beneficial nutrients (e.g. phytochemicals and prebiotics) that promote health and potentially prevent diseases. The investigators will determine if dietary rice bran intake can modulate the infant gut microbiome and metabolome to promote gut immunity for the benefit of preventing diarrheal diseases that increase risk for malnutrition and stunting.
The investigators hope to learn about the feasibility of dietary supplementation of heat-stabilized rice bran in weaning children living in regions with increased susceptibility to diarrhea and malnutrition, and whether or not rice bran consumption can modulate the stool microbiome and metabolome.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Observational ControlOther
Participants will be observed and not provided any dietary supplementation.
Rice branDietary supplement
Also called whole food dietary intervention
Dietary rice bran consumed daily and amounts increase throughout the 6 month intervention (6 months of age: 1 g/day rice bran, 7 months: 2 g/day rice bran, 8 months: 2 g/day, 9 months: 3g/day, 10 months: 4g/day, 11 months: 5g/day).
| Study group | Role | What they receive |
|---|---|---|
| Observational Control | Experimental | Randomized participants will be observed for diarrhea incidences throughout the 6 month trial with no intervention. Receives: Other: Observational Control |
| Rice Bran | Experimental | Randomized participants will consume a measured dose of rice bran daily throughout the 6 month trial. Receives: Dietary Supplement: Rice bran |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants who are compliant to consuming rice bran daily and in amounts provided
Record daily rice bran consumption and track compliance to diet intervention by regular visits from local study personnel.
Measured: 6 months
Secondary outcomes (2)
Number of participants with microbial modulations in stool as detected by microbiome sequencing.
Measure the stool microbiome modulation with rice bran consumption for gut health and diarrhea prevention compared to no rice bran consumption.
Measured: 6 months
Number of participants with metabolite modulations in stool as detected by Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS)
Measure the stool metabolome modulation with rice bran consumption for gut health and diarrheal prevention compared to no rice bran consumption.
Measured: 6 months

Where is the study taking place?
The record lists 2 sites in United States, Nicaragua. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants who are compliant to consuming rice bran daily and in amounts provided (time frame: 6 months). 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 NCT02615886, which also lists 6 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jul 2017.
