Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed My Nutritional Health (MNH) app is a unique tool for consumers interested in tracking their food intake and linking diet to symptoms.

The investigators will test this app for developmental purposes among a sample of 100 participants who are patients of dietitians at Cedars-Sinai Medical Center (CSMC) and the University of Michigan (UM) with varying presentation of GI symptoms and suspected food intolerances. The MNH app built on the LifeData app will be used as a data collection platform for this study and can be utilized by iOS and Android smartphone devices. The investigators will use the data collected in the app testing to develop population-level FAST scores.

The MNH app includes two integrated functions:

1. Patient Symptom and Food Consumption Reporting
2. FAST Score calculation It is important to note that, per this protocol, the MNH app will only be evaluated for developmental purposes. It is currently not meant to serve as a diagnostic tool, nor to provide referrals for patients with food and symptom patterns that may suggest a food intolerance. In this respect, our test app is not governed by FDA or other regulatory bodies, as it does not make diagnoses or offer specific guidance. The purpose of this study is only to develop normative scoring distributions of FAST within the context of patients visiting GI dietitians as part of routine care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study aims are:

AIM 1 - To validate the FAST Instrument against existing patient-reported outcome (PRO) measures.

AIM 2 - To assess sensitivity of the FAST instrument to changes in patient diet.

Investigators will collect information about food intake and related symptoms using the MNH app to validate the FAST instrument and assess its sensitivity to change in patient diet. For this study, 100 participants who are scheduled to see participating dietitians at either Cedars-Sinai Medical Center or the University of Michigan will be recruited.

Participants will be asked to report information regarding food intake and symptoms for two weeks (one week pre- and one week post-dietitian visit). The MNH app will prompt users to log food intake and any symptoms that you are experiencing at multiple time points throughout the day. Investigators will reach out to participants via telephone during the first week of enrollment to inquire about their progress using the app, assist in troubleshooting for technical difficulties, and answer any questions.

At the end of each week, participants will be asked to respond to a standardized questionnaire about GI symptoms (the 15-item Gastrointestinal Symptom Rating Scale; GSRS) and a questionnaire about general health status (the PROMIS 10 Global Health, a 10-item questionnaire developed by NIH) through the MNH mobile app.
