Feature: Actigraphy for Sleep Tracking
Review by Trish Stiger
Actigraphy has been used to study sleep/wake patterns for over 20 years. It is predominantly used to assist in diagnosing insomnia, circadian rhythm disorders, excessive sleepiness, and periodic limb movement disorder.
According to a study presented at APSS this year and reviewed in Sleep Review, Fitbit tracking devices accurately track light, REM and deep sleep stages when compared to a Type III home sleep testing device. The estimated Cohen’s kappa was 0.52, indicating a strong agreement between the methods.
The technology has been used to track over 4 billion nights of sleep. This provides a broad look a population trends and provides “big data” to allow analysis of defined groups. Fitbit data was used to evaluate sleep patterns by gender and generation. The data shows Generation Z sleeping the most and Baby Boomers sleeping the least. On average, women sleep 25 more minutes a night than men. While these devices are shown to accurately track sleep it is important to keep in mind that there are many other parameters that must be taken into account if evaluating sleep for medical/ diagnostic purposes.
