Bidirectional associations between sleep and physical activity investigated using large-scale objective monitoring data.

ABSTRACT:

Background

The extent to which people routinely co-attain recommended sleep and physical activity levels, as well as bidirectional associations between both health behaviours, are poorly understood at the global level. This study aimed to describe the routine co-attainment of adequate sleep and daily step count thresholds and investigate non-linear associations between objective sleep and daily step count in a large multi-national sample of objective health monitoring data.

Methods

Data were collected from 70,963 users of two consumer-available health devices-an under-mattress sleep sensor and wrist-worn health tracker-between January 2020 and September 2023. Generalised additive models were used to investigate potentially non-linear, bidirectional, exposure-response relatio
