NCT03663530

Brief Summary

Preliminary findings from the investigators' lab suggest that circadian misalignment, occurring when meals and sleep are mistimed from one another, alters resting state neuronal processing in areas relevant to food reward and interoception; supporting a role of sleep and meal misalignment, on energy balance regulation. No study has been done to disentangle the effects of sleep and meal timing on body weight regulation, independent of sleep duration. This study will provide information to guide messaging related to timing of meals and sleep that can be translated to individuals whose sleep follows unconventional times, such as shift workers and those with jetlag and social jetlag.

Data from this study will be available for sharing with other investigators. Data sharing requests should be made in writing and sent directly to the investigator(s) who generated the data. The purposes for using shared data should be stated in the request, and the data can only be used for research purposes. Data sharing agreements should be developed and accepted by both parties before data sharing takes place. Protecting the rights and privacy of human subjects and maintaining the study participants' confidentiality will be the first priority of our data sharing plan. We plan to follow the HIPAA privacy rule for de-identification of a dataset before transferring data.

Shared Documents
STUDY PROTOCOL, ICF
Time Frame
Data will become available after results of the main aims from the final dataset have been accepted for publication.
