About

This study is designed to test the effects of diet data return on human dietary patterns. The investigators' working hypothesis is that returning diet data, collected via an empirical biomarker-based assessment method, will promote participant eating behavior changes towards a more healthful diet, and that these dietary patterns may also be reflected in the structure and function of the gut microbiome and in participant health outcomes. Here, the investigators will explore this hypothesis with participants supplying stool (poop) samples that will be used to assess their diet using the investigators' DNA-biomarker based method. Participants will have their diet data returned to them, and will then supply post-intervention stool samples for dietary assessment to investigate the efficacy of diet data return in impacting subject dietary patterns and health. It is anticipated that the investigators will enroll infants, children, and adults across the age span, including infants that are currently participating in Project HOPE 1000, a longitudinal observational study of mothers and infants from pregnancy through early childhood (Pro00100000). This study represents a minimal risk to subjects; namely, the potential loss of privacy involved with study participation.

Enrollment: 600 estimated patients

Sex: All

Ages: Under 12 months old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participant's parent/legal guardian is over age 18 and able to understand English
• Plans to remain in the area for the next two years
• Primary caregiver for infant less than 12 months old
• Able to collect and ship the requested infant stool samples

Exclusion criteria

There will be no specific exclusions for this study. However, the following biospecimens will not be collected for research purposes from individuals who have a condition that, in the opinion of the site investigators and/or providers, would place the subject at unacceptable risk of injury or confound data interpretation; including but not limited to:

• Health conditions that impact the infant feeding in a way that may confound interpretation of study results.

600 participants in 2 patient groups

Intervention

Other group

Description:

Participants in this group will receive the standard infant dietary guidance packet via email or mail and will additionally be presented with their infant's own dietary DNA metabarcoding data from stool samples collected as part of Project HOPE 1000 and this study. Diet data will be returned via electronic report or a paper report mailed to the participant following the visit.

Treatment:

Behavioral: Personalized Diet Information

Control

Other group

Description:

Participants in this group will receive a dietary information packet via mail or email, which will consist of the sections of the DGA relevant to 12-24 month old children (Included as a supplemental document, "Standard dietary guidance"). This dietary guidance will also be provided at the 18- and 24-month visits. Please note that participants in this arm will receive their personalized diet information at the conclusion of the study.
