Study Details

Brief summary:

The purpose of this study is to determine the feasibility of capturing daily dietary intake of patients undergoing radiation therapy using a mobile food record. This is a prospective single group, non-randomized, feasibility study.

20 participants will be identified during routine clinical care visits with the study PI or co-investigators. Consent will be obtained in person during a clinic visit or using the e-consent process described in section 21.1. They will be asked to use the myCircadian Clock (mCC) app to document their dietary intake for the duration of their radiation treatment. No follow up data will be collected.

Interventions and Outcome Measures

Arms

experimental: Mobile Food Record

Participants will use the myCircadian Clock (mCC) app to document all dietary intake throughout the course of their radiation therapy.

Interventions

Mobile food record using myCircadian Clock app

Participants will use the myCircadian Clock (mCC) app to document all dietary intake. The mCC app serves as a research-based mobile food record by capturing the food image coupled with the participant's free-text entry to self-describe the food. The participants will be asked to document all dietary intake throughout the course of their radiation therapy. All dietary intake will be tracked other than water and medications.

Primary outcome measure

  • Feasibility of completing mobile food record during radiation therapy [ Time Frame: Throughout the course of radiation therapy, which can last from 1 to 35 business days. ]
