Brisk Walking Training Compared with Cognitive Behavioral Therapy for the Treatment of Chronic Primary Insomnia in People Aged 60 Years or Above: a Randomized, Partially Blinded, Non-inferiority Trial

This study is a single-blinded (outcome assessor) and parallel-group non-inferiority RCT. Chinese older adults aged ≥60 years with chronic primary insomnia will be randomized evenly (1:1) to either the brisk walking training group or the CBT-I group. Participants in the brisk walking training group receive an eight-week instructor-led interval brisk walking training (40 minutes/session, three sessions/week). Participants in the CBT-I group receive standard-of-care group-based eight-session CBT-I (one session/week). Self-reported and objective sleep outcomes are measured at baseline (T0), after completion of the intervention (T1), and six (T2), and 12 months after T1 (T3).
