Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Affect Recognition domain	Measured using the assessor-administered Developmental Neuropsychological Assessment-Second Edition (NEPSY-II). Scaled scores for each subtest consist of a mean of 10 and a standard deviation of 3 (range of 1-19). Higher scores indicate superior performance.	5.5 years of age
Other	Inhibition domain	Measured using the assessor-administered Developmental Neuropsychological Assessment-Second Edition (NEPSY-II). Scaled scores for each subtest consist of a mean of 10 and a standard deviation of 3 (range of 1-19). Higher scores indicate superior performance.	5.5 years of age
Other	Design Fluency domain	Measured using the assessor-administered Developmental Neuropsychological Assessment-Second Edition (NEPSY-II). Scaled scores for each subtest consist of a mean of 10 and a standard deviation of 3 (range of 1-19). Higher scores indicate superior performance.	5.5 years of age
Other	Statue domain	Measured using the assessor-administered Developmental Neuropsychological Assessment-Second Edition (NEPSY-II). Scaled scores for each subtest consist of a mean of 10 and a standard deviation of 3 (range of 1-19). Higher scores indicate superior performance.	5.5 years of age
Other	Visual-Motor Integration	Measured using the assessor-administered Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI). Standard scores with a mean of 100 and a standard deviation of 15 will be reported. Higher scores on the Beery VMI indicate superior performance.	5.5 years of age
Other	Social-Emotional Functioning	Social-Emotional functioning as measured by parent-report using the Social Responsiveness Scale Second Edition (SRS-2). T-scores on the SRS-2 have a mean of 50 and standard deviation of 10. Higher scores are associated with more severe social impairments.	5.5 years of age
Other	Behaviour and Emotional Response	Behaviour and Emotional Response as measured by parent-report using the Behavior Assessment System for Children-Third Edition (BASC-3). Scores are expressed as T-scores with a mean of 50 and standard deviation of 10. Higher values indicate increased risk for composites of clinical scales and lower risk for the composite of adaptive scales.	5.5 years of age
Other	Executive Functioning	Executive Functioning as measured by parent-report using the Behavioral Rating Inventory of Executive Function (BRIEF). T-scores have a mean of 50 and a standard deviation of 10. Higher scores indicate a potential problematic area of clinical significance.	5.5 years of age
Other	Sensory Processing	Sensory Processing related to auditory, visual, touch, movement, body position and oral processing as measured by parent-report using the Sensory Profile Second Edition (Sensory Profile-2). Higher scores indicating higher sensitivity in each category.	5.5 years of age
Other	Gross Motor Development	Measured using the assessor-administered Movement Assessment Battery for Children Second Edition (Movement ABC-2). Higher scores indicate superior performance.	5.5 years of age
Other	Influence of the diet on epigenetic changes	Assessed using a buccal cell biorepository.	5.5 years of age
Other	Influence of genetics on taste	Assessed using a buccal cell biorepository.	5.5 years of age
Other	Fatty acid status	Assessed using a buccal cell biorepository.	5.5 years of age
Other	Children's eating behaviours and dietary intake	Assessed using direct observation during a standardized lunch protocol.	5.5 years of age
Other	Children's eating behaviours	Assessed by parent-report using the Child Eating Behaviour Questionnaire (CEBQ). The CEBQ is made up of eight scales: Food responsiveness, Emotional over-eating, Enjoyment of food, Desire to drink, Satiety responsiveness, Slowness in eating, Emotional under-eating, and Food fussiness. Higher scores indicate higher frequency behaviour.	5.5 years of age
Other	Food parenting and parent dietary intake	Assessed using direct observation during a standardized lunch protocol.	5.5 years of age
Other	Food parenting	Assessed by parent-report using the Comprehensive Feeding Practices Questionnaire (CFPQ). The questionnaire contains 12 scales: 'Encourage Balance and Variety', 'Environment', 'Involvement', 'Modeling', 'Monitoring', 'Teaching about Nutrition', 'Emotion Regulation', 'Food as Reward', 'Pressure', 'Child Control', 'Restriction for Health' and 'Restriction for Weight Control'; higher scores indicate higher frequency behaviour.	5.5 years of age
