What this trial studies

This observational study aims to explore the relationship between sleep health and cardiovascular disease (CVD) risk factors in Singapore, a city known for its high levels of sleep deprivation. By utilizing objective sleep tracking through wearables, the study will assess various dimensions of sleep, including duration, timing, regularity, and efficiency, alongside health assessments related to cardiovascular conditions. The research will also consider the impact of mental health factors, such as depression and stress, on cardiovascular health. The goal is to gain insights into how poor sleep may contribute to the progression of CVD among individuals with existing risk factors.
