An observational study in Breast Milk Collection, sponsored by University of Turku. Completed at 1 site in Finland. Open to female participants aged 18 Years to 45 Years. Per ClinicalTrials.gov, last updated 2026-05-07.
Sponsored by University of Turku · Observational
The biochemical differences in the composition of breast milk and formula have not been profoundly established in all compound groups. Increased understanding of breast milk composition, the normal variation of various bioactive compounds and their levels is required to be able to develop formulas better corresponding the breast milk, and ensure the optimal development of also the formula-fed babies.
88 studies on the registry are indexed under Breast Milk Expression; 20 are open to participants now.
This study's enrollment of 7 is below the median of 71 across 36 observational studies indexed under Breast Milk Expression.

Exclusion Criteria:
A single breast-milk sample will be collected from 20 women who breast-feed their child (0-6 months old).

Ran from Nov 2018 to primary completion in May 2022, 42 months.
Of 25 observational studies under Breast Milk Expression, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 44. This study's 42 months is above that.
