The National Cancer Institute (NCI) has made available an updated version of the Automated Self-Administered 24-Hour Recall (ASA24), an online dietary assessment tool. It may be of particular interest to sleep and circadian clinical researchers studying the relationship of sleep deficiency to metabolic disorders, appetite regulation and obesity. ASA24T is available to researchers free of charge. Note that using the tool requires “registering” studies to enable Web access. View an ASA24 online demonstration.
