Remote Food Photography Method in Infants (BabyBottle)

Baby Bottle: Remote Food Photography Method in Infants

The purpose of this study is to determine if digital photography on a Smartphone and the Remote Food Photography Method (RFPM) can estimate infant formula intake. This is a validation study; there is no hypothesis.

2

Cohorts and Interventions

Group / Cohort
Cohort 1; All participants enrolled between November 2012 and March 2013 under the original protocol.
Cohort 2; After Cohort 1 was completed, the study investigators changed the protocol to eliminate the photograph/weight of the powdered formula alone in each bottle to reduce burden. All other protocol procedures remained the same. Cohort 2 participants enrolled between April 2013 and May 2014.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Kilocalorie (Kcal) Difference Between Methods for All Prepared Bottles	Kilocalorie (Kcal) Difference in prepared infant formula intake detected in a bottle between the Remote Food Photography Method (RFPM) and direct weighing Kilocalorie difference between the Remote Food Photography Method and direct weighing with all bottles that were prepared included Kilocalorie difference is Remote Food Photography Method - Direct Weighing	Measures will be performed twice about 5-10 days apart

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Kilocalorie (Kcal) Difference Between Different Bottle Sizes	Kilocalorie difference between the Remote Food Photography Method and direct weighing separately analyzed by the four different bottle sizes that were prepared (2 oz bottles only, 4 oz bottles only, 6 oz bottles only, and 8 oz bottles only). Each participant prepared 3 sets of 2 oz bottles, 3 sets of 4 oz bottles, 3 sets of 6 oz bottles, and 3 sets of 8 oz bottles and all bottles of the specified size were included in the analysis. Kilocalorie difference is Remote Food Photography Method - Direct Weighing	Measures will be performed twice about 5-10 days apart

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Gram Weight of Infant Formula Provision Between Participants Who Identified as Infant Caregivers and Infant Non-caregivers for 2 oz Prepared Bottles Only	A caregiver will be defined as an individual who is a parent, grandparent, sibling, aunt or uncle, or nanny or babysitter who has provided care to an infant within the last 12 months. Gram weight by direct weighing comparing the caregivers and non-caregivers in infant formula provision (not simulated intake) in 2 oz prepared bottles only. Each participant prepared 3 sets of 2 oz bottles, and all bottles of the specified size were included in the analysis.	Measures will be performed twice about 5-10 days apart
Gram Weight of Infant Formula Provision Between Participants Who Identified as Infant Caregivers and Infant Non-caregivers for 4 oz Prepared Bottles Only	A caregiver will be defined as an individual who is a parent, grandparent, sibling, aunt or uncle, or nanny or babysitter who has provided care to an infant within the last 12 months. Gram weight by direct weighing comparing the caregivers and non-caregivers in infant formula provision (not simulated intake) in 4 oz prepared bottles only. Each participant prepared 3 sets of 4 oz bottles, and all bottles of the specified size were included in the analysis.	Measures will be performed twice about 5-10 days apart
Gram Weight of Infant Formula Provision Between Participants Who Identified as Infant Caregivers and Infant Non-caregivers for 6 oz Prepared Bottles Only	A caregiver will be defined as an individual who is a parent, grandparent, sibling, aunt or uncle, or nanny or babysitter who has provided care to an infant within the last 12 months. Gram weight by direct weighing comparing the caregivers and non-caregivers in infant formula provision (not simulated intake) in 6 oz prepared bottles only. Each participant prepared 3 sets of 6 oz bottles, and all bottles of the specified size were included in the analysis.	Measures will be performed twice about 5-10 days apart
Gram Weight of Infant Formula Provision Between Participants Who Identified as Infant Caregivers and Infant Non-caregivers for 8 oz Prepared Bottles Only	A caregiver will be defined as an individual who is a parent, grandparent, sibling, aunt or uncle, or nanny or babysitter who has provided care to an infant within the last 12 months. Gram weight by direct weighing comparing the caregivers and non-caregivers in infant formula provision (not simulated intake) in 8 oz prepared bottles only. Each participant prepared 3 sets of 8 oz bottles, and all bottles of the specified size were included in the analysis.	Measures will be performed twice about 5-10 days apart
