Lifestyle Assessment of Large Scale Population using Repose - A Heart Rate Variability based Lifestyle Assessment Platform

In today's fast-paced and pandemic-hit world, there is an obstinate need for a lifestyle assessment for every individual to understand and assess their overall well-being. It is harder to define mental health than physical health because most of the psychological diagnoses depend on an individual's perception based on their personal experiences. There are numerous questionnaire-based lifestyle assessment surveys available but they are subjective in nature and are highly prone to perception bias. The need of the hour is physiology-based methods that are objective and hence reliable. Repose is Asia's first Heart Rate Variability (HRV) based lifestyle assessment platform using the Electrocardiogram (ECG) signal. The platform consists of a chest-based wearable device, mobile application and web application and is capable of recording data continuously for 24 hours and provide reports for the same. The key pillars of lifestyle namely, stress, recovery, sleep and physical activity are quantified and valuable insights are provided to the user. This paper explains the utility and usability of Repose platform and the statistical observations of the results obtained using the Repose platform for a large scale population. The statistical results for 24-hour lifestyle assessments for 492 subjects for the duration spent in stress recovery regions and sleep quality and insights on physical activity are presented in this paper.
