In this study the researchers want to learn more about reward-driven eating behavior in children ages 2 to 18 months. The researchers hope to use this knowledge to help inform obesity prevention programs.

The study will comprise two arms and each arm has a different time perspective. The longitudinal arm is prospective in nature and the cross-sectional arm has a cross-sectional time perspective. The video observation is completed at a single time point (although standardized by inclusion criteria).

For the Longitudinal Arm:

Inclusion Criteria

• Baby is alive

• Baby is 6 to 16 weeks old at time of enrollment

• Baby and mother receive care at Michigan Medicine, and specifically:

  • Baby was born at Michigan medicine
  • Baby has had a 2 month well child check
  • Mother received prenatal care at Michigan Medicine
  • Mother has a linked patient profile to baby's profile
  • Baby has a length and weight measurement on record

• Mother is English speaking

Exclusion Criteria

• Baby is a foster child
• Baby was still in hospital 4 days after birth
• Baby has severe perinatal or neonatal medical problems
• Baby has severe developmental delays
• Multiple births

For the Cross Sectional:

Inclusion Criteria

• Enrolled in longitudinal arm of study
• Eligible to complete all three protocols (Two Oatmeal and Reaching) as per protocol screeners
• Baby is alive
• Baby is 5 to 7 months old at the time of enrollment
• Mother is biological mother
• Mother is legal guardian
• Mother is English speaking

Exclusion Criteria

• Baby had severe perinatal or neonatal medical problems
• Baby currently has severe medical problems
• Baby has severe developmental delays
• Mom had severe complications during pregnancy
• Multiple Births
• Food allergies

The researchers will enroll infants and their mothers (age limit given is for minimum age for mothers) from the community and from sites allowed and approved by the IRB like pediatric clinics and childcare centers. They will be recruiting participants living within a 50 mile radius around Ann Arbor, MI.

The research will generate demographic, anthropometric, dietary, behavioral questionnaire, and coded behavioral data. (Note the researchers will not make video data available.) The data will be stored as Statistical Package for the Social Sciences (SPSS) or Statistical Analysis System (SAS) files. Meta data will also be included in the selected repositories.The meta data will include the data dictionaries, which describe the generation of all variables, as well as the protocol manuals describing the behavioral protocols used to generate the variables.

Data submitted to Deep Blue Data will be reviewed after 10 years to determine if a dataset should be retained and will be subject to further, periodic, reviews thereafter.

All data in the Deep Blue Data repository are available to anyone for download without restriction.
