Micronutrient Status During Pregnancy
An observational study of Deficiency Vitamins, run by Haukeland University Hospital.
Trial summary
An adequate micronutrient status during fetal life and infancy is important for optimal development. Dietary practices during pregnancy, lactation and infancy vary among populations and there is today no clear agreement on what constitutes the best diet, including micronutrient supplementation, during this period.

About this study
Official title: Micronutrient Status in Pregnant and Lactating Women and Their Infants
An adequate micronutrient status during fetal life and infancy is important for optimal development. Dietary practices during pregnancy, lactation and infancy vary among populations and there is today no clear agreement on what constitutes the best diet, including micronutrient supplementation, during this period. There is consequently no clear agreement on what constitutes an optimal biochemical micronutrient status in mothers and infants. Due to substantial physiological changes in plasma volume, hormones, transport proteins and organ function during these periods, the ordinary reference levels or cut off levels used for biochemical assessment of micronutrient status are unsuited to these groups of patients.
The objective of the study is to establish cut off levels for important vitamins and trace elements during pregnancy, lactation and infancy in order to ensure an optimal infant neurodevelopment and to study how micronutrient status influence the immunosystem.
Read the detailed description
The investigators have analyzed micronutrients, including all vitamins and trace elements and related aminoacids and markers of cellular immunoactivation in 160 fertile, unpregnant women, 115 pregnant women from pregnancy week 18, throughout pregnancy and the first 6 postpartum months and their infant at 6 months. Infant gross motor development is associated with micronutrient status, so the investigators will relate gross motor development at 6 months to maternal micronutrient status during pregnancy and postpartum, in order to establish relevant cut off levels for micronutrients and related biomarkers.

Questions about this trial
What is this clinical trial studying?
An observational study of Deficiency Vitamins, run by Haukeland University Hospital.
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 1 Mar 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?
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?
Change in micronutrient status during pregnancy and lactation (time frame: The investigators will study change in micronutrients during pregnancy and lactation). 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 NCT03272022, which also lists 7 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 1 Mar 2023.
