An experienced nurse drew 2 mL venous blood from infants at baseline and endpoint into anticoagulant-coated tubes.
Within a community-based maternal and newborn care intervention with health systems strengthening, we collected data from mothers with infants at baseline and endline using a structured questionnaire.
Mothers in the control group tended to have higher levels of RF and better quality interactions with their infants at baseline than those in the intervention group.
The mean age of the infants at baseline was 18.6 weeks (± 4.3, range 9.4 - 31.6) with 97% being breastfed at some stage since birth and 73.2% still breastfed to some extent at the time the questionnaire was completed (57.8% fully breastfed, 15.4% breast plus formula).
Outcomes (infant growth, MR, FS, FP) and maternal and infant factors at baseline (self-efficacy, knowledge, infant age, temperament, type of feeding) will be compared across intervention and control groups using t-test for continuous variables and chi-square test for categorical variables [ 149, 150].
While in the scanner, mothers rated their mood more positively for pictures of their own infants than for unfamiliar infants, adults, or at baseline.
According to ITT analysis, 110 preterm infants were analyzed at baseline.
Serum lutein concentrations were determined from infant blood samples collected at baseline and week 12. Whole blood (1 2 ml) was obtained from each infant by venipuncture by a registered pediatric phlebotomist or by heel stick by a pediatric registered nurse.
Maternal blood and breast milk, and infant blood, were collected at baseline.
We also noted that therapists found it difficult to predict the rate of infant's motor development at baseline given the limited motor repertoire at enrolment age and the lack of a robust severity measure for infants.
