Evaluation of Different Protein Content of Formulas on Nutrition Status of Infants.
A study testing Infant formula in people with Growth & Development and Formula Feeding of Healthy Full Term Infants, run by Universidad Autonoma de Queretaro at 1 site in Mexico.
Trial summary
Human milk (HM) is the gold standard of early infant nutrition. The World Health Organization (WHO) recommend that newborns be exclusively breastfed for the first 6 months of life. It has beed reported that an exclusive breast feeding at 6 months of age range from 10 to 46%. Read more about this study

About this study
Official title: Evaluation of the Impact of Infant Formulas With Different Protein Content on Growth, Gastrointestinal Tolerance, and B-casomorphin Concentration of Infants.
Human milk (HM) is the gold standard of early infant nutrition. The World Health Organization (WHO) recommend that newborns be exclusively breastfed for the first 6 months of life. It has beed reported that an exclusive breast feeding at 6 months of age range from 10 to 46%. Thus, the intake of infant formulas (IF) is quite widespread, including infants that have less than 6 months that are not receiving breast milk. Most of the commercial IF are cow's milk-based formulas that have a higher concentration of protein than breast milk and have a different protein composition. Commercial IF have a low proportion of alpha lactoalbumin, and A1 β-casein; during its digestion, a β-casomorphin 7 peptide is produced. In addition, it has a high concentration of β-lactoglobulin. Both, β-casomorphin 7 and β-lactoglobulin have been associated with a higher risk of diabetes obesity and allergies. Human β-casein does not produce β-casomorphin 7 during its digestion, it has a high concentration of alpha-lactoalbumin and does not have β-lactoglobulin.
The purpose of this study is to evaluate growth, gastrointestinal tolerance, and β-casomorphin 7 in urine of infants that are exclusively breastfed compared to infants fed three IF with different proteint content.
Read the detailed description
Developing an IF with A2 β-casein, high proportion of alpha-lactoalbumin and less protein that commercial IF, similar to breast milk (1g/100 mL), could be and important strategy to decrease the risk of diseases. This infant formula was compared with breast milk and two other IF with different protein composition. The three formulas were packed in the same presentation and identified by a number. Mothers voluntarily elected to exclusively breast-feed or formula-feed her newborn. the present study
Infants' mothers were recruited from six health centers from the Health Ministry in Querétaro, México. Directors of each health center authorized the protocol study. The field workers were read and explained the informed consent letter, the objectives, procedures, risks and benefits of the study in detail.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in weight
Weight
Measured: Baseline to 4 months of age
Secondary outcomes (3)
Anthropometry measurements
Measurements will include length and head circumference, and together with the primary outcome of weight, will be used to calculate z-scores using WHO Growth Standards.
Measured: Baseline, 1, 2 ,3 and 4 months of age
Beta-casomorphin 7 concentration
Quantification of beta-casomorphin 7 concentration in urine
Measured: Baseline and at 4 months of age
Number of gastrointestinal events
Gastrointestinal events will be recorded by the mothers. These events include: constipation, diarrhea, regurgitation, vomit, reflux, colic, constant crying, and stool consistency and color, using previously reported scales (Bekkali et al, 2009; Trabulsi, 2011).
Measured: Baseline, 1, 2, 3, and 4 months

Where is the study taking place?
The record lists 1 site in Mexico. 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?
Change in weight (time frame: Baseline to 4 months of age). 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 NCT03513991, 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 2 May 2018; AzTrials last refreshed its copy on 7 Nov 2026.
