Circadian rhythms are crucial to human health and have become a popular topic in clinical research in recent years. In the past, wearable devices (e.g., actigraphy) have been widely used to assess circadian rhythms by monitoring physical activity. While actigraphy is convenient and validated as an accurate research tool, it is less popular than smartphones, which nearly everyone owns. On the other hand, many medical-purpose mobile apps exist, but none can automatically record circadian rhythms. We are interested in using human-smartphone interactions (i.e., digital footprints) to assess circadian rhythms and explore the correlations between sleep, depression, and obesity.<\/span><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

We developed ‘Rhythm,’ a mobile app to capture digital footprints. This app serves as a foundation for establishing \u2018digital biomarkers,\u2019 enabling long-term recording and measurement of daily activity and sleep patterns. There are three variables that reflect circadian rhythm: Intradaily Variability (IV), Relative Amplitude (RA), and Intradaily Stability (IS). Our research shows that \u2018Rhythm\u2019 produces results comparable to actigraphy, not only in effectiveness in reading circadian rhythms but also in offering more detailed insights into mental activity.<\/p><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

We found that participants’ mental and physical health scores are related to their circadian rhythms: Intradaily Variability (IV) is significantly correlated with depressive symptom scores, and Interdaily Stability (IS) is significantly correlated with obesity. We believe the \u2018Rhythm\u2019 app and its algorithm can assist clinicians in providing more accurate diagnoses and treatment for patients, particularly those with mood disorders. Future research will explore the clinical value of the \u2018Rhythm\u2019 app in other areas.<\/p><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
