Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In Canada, the leading cause of long-term disability in children is being born at very low birth weight (VLBW). To help improve outcomes, nutrition is a modifiable aspect of infant care. Mother's milk is the optimal way to feed VLBW infants; however, many need a supplement of donor milk or preterm formula as not enough mother's milk is available. As the ideal supplement for prolonged feeding and its long-term effects is currently unknown, this study is a prospective follow-up of infants born VLBW who were fed mother's own milk or pasteurized donor breastmilk nutrient enriched with a human milk-based fortifier or a bovine protein-based fortifier. Intakes of donor milk, fortifier type, macronutrients and fatty acids will be explored. Areas of development to be assessed include: cognition, language, motor skills, and body composition. This study will also cross-sectionally examine aspects of eating behaviours, food parenting and the home environment (e.g., stress, home chaos, family functioning) with a term-born comparison. A DNA biorepository will also be created.

Children previously enrolled in the OptiMoM Fortifier Study

This is an observational study of children who were previously enrolled in a trial (Bovine vs. Human Milk-Based Fortifier Study) between 2014 and 2016 during which time they were randomized to have their feeds (mother's own milk or pasteurized donor breastmilk) nutrient enriched with a human milk-based fortifier or a bovine protein-based fortifier.

VLBW

Intervention Type OTHER

Participants previously enrolled in the Bovine vs. Human Milk-Based Fortifier Study

Term-born Comparison

This is an observational study of children born at full term (\>= 37 weeks gestation) and weighing more than 2500g. These children will be recruited from the communities in which the OptiMoM participants live.
