About this study

Official title: The Effects of Prenatal Multi-micronutrient Supplements on Pregnancy Outcome, Peri- and Neonatal Mortality on Maternal and Infant Nutritional Status: A Randomised, Controlled Trial Among Women in Guinea-Bissau

Prenatal maternal micronutrient supplementation has been suggested as a means to reduce the proportion of low birth weight babies in low-income countries. The effects of prenatal multi-micronutrient supplements on birth weight and perinatal mortality were studied in a randomised controlled trial among 2100 pregnant women in Guinea-Bissau. Women up to 37 weeks pregnant were individually randomised to daily supplements until delivery of A) Iron + folic acid or multi-micronutrients in B) One or C) Two recommended dietary allowances. Secondary outcomes were infant growth and maternal haemoglobin eight weeks after delivery.

Prenatal maternal micronutrient supplementation has been suggested as a means to reduce the proportion of low birth weight babies in low-income countries. The effects of prenatal multi-micronutrient supplements on birth weight and perinatal mortality were studied in a randomised controlled trial among 2100 pregnant women in Guinea-Bissau. Women up to 37 weeks pregnant were individually randomised to daily supplements until delivery of identically looking tablets containing 1) Iron (60 mg) + folate (400 µg), 2) One recommended dietary allowance (RDA) of 5 minerals and 10 vitamins, including iron (30 mg) and folate (400 µg), or 3) Two RDA's of 5 minerals and 10 vitamins, including iron (30 mg) and folate (800 µg). Supplements were provided in known excess at fortnightly home visits until delivery. Compliance was assessed by tablet count.

Women were interviewed about age, civil status, obstetric history and socio-economic status at enrolment. Maternal anthropometry was measured at enrolment, at delivery, and eight weeks after delivery. Maternal malaria parasitaemia and haemoglobin were measured at enrolment and eight weeks after delivery. Maternal status of a wide range of micronutrients was assessed at enrolment and eight weeks after delivery in a sub-cohort of 600 women. Further, survival of the infants will be followed until 3 years of age, within the routines of the Bandim Health Project surveillance system.

Women were provided impregnated bed nets and weekly malaria prophylaxis until delivery. Women with high malaria parasitaemia at enrolment were in addition given a full treatment at enrolment.

Sample size considerations: A sample size of 638 women in each treatment group will be required to detect a reduction in perinatal mortality from 9% to 5% or less in a treatment group using 80% power and a 5% significance level. With an expected loss to follow up of 10%, 2100 women are required. With a sample size of 2100 the study will be able to detect at least 75 g difference, i.e. a 2.5% change in birth weight.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing multi micronutrient supplement, MN1 and MN2 in people with Pregnancy and Birth Weight, run by Bandim Health Project at 1 site in Guinea-Bissau.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 18 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Guinea-Bissau. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Birth weight (<3 days). The study lists 2 primary outcomes in all. 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 NCT00168688, which also lists 1 linked publication.

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 18 Nov 2013.
