Outcome Measures
Primary Outcomes (1)
Conditional weight gain z-score changes (CWGz)
CWGz scores will be calculated for each participant as the residual of the actual weight-for-age z-score at 4 months minus its predicted z-score from linear regression of the 4 month z-score on birth weight z-score. Intent-to-treat analyses will include regression models, stratified by sex, with CWGz score as the outcome.
Birth to 4 months
Secondary Outcomes (2)
Formula volume per feed
Birth to 4 months
Caregiver sensitivity to cues as measured by the Nursing Child Assessment Feeding Scale (NCAFS)
Birth to 4 months
