Trial Outcomes & Findings for Effect of Infant Formula on Energy Balance (NCT NCT01700205)
NCT ID: NCT01700205
Last Updated: 2019-11-22
Results Overview
At each visit, infants were weighed and measured to monitor normal growth. These anthropometric data were converted to weight-for-length (WLZ) Zscores using World Health Organization (WHO) growth standards. The Z-score expresses the anthropometric value as a number of standard deviations or Z-scores below or above the reference mean value. Normal range for Z score is -2.0 (minimum) to 2.0 (maximum).

Participant Flow
From 2012 to 2015, newly parturient women whose decision not to lactate was firmly established were recruited through ads in regional newspapers, websites and hospitals in the greater Philadelphia area.

PRIMARY outcome
Timeframe: 0.5 to 12.5 months with followup visit at 18.5 mosPopulation: We conducted an intention-to-treat (ITT) analyses on 113 infants regardless of study withdrawal.
At each visit, infants were weighed and measured to monitor normal growth. These anthropometric data were converted to weight-for-length (WLZ) Zscores using World Health Organization (WHO) growth standards. The Z-score expresses the anthropometric value as a number of standard deviations or Z-scores below or above the reference mean value. Normal range for Z score is -2.0 (minimum) to 2.0 (maximum).

SECONDARY outcome
Timeframe: 0.5 monthsPopulation: Some mothers responded N/A on questions related to restrictive feeding styles and thus score for this subscale could not be computed.
Maternal perception of infant feeding behavior, using standardized questionnaires (Infant feeding style questionnaire; IFSQ); values ranged from 1 to 5; higher scores reflect more of that feeding style. Only baseline data reported herein.
