Association of light exposure on physical activity and sedentary time in young people.

ABSTRACT:

Background

To investigate whether light exposure was associated with objectively measured physical activity (PA) and sedentary behaviour in young people.

Methods

Participants (n=229, 46.7% female) were young people (mean 8.8 years [SD±2.2]) from the borough of Camden, UK. Daily sedentary time, moderate and vigorous PA (MVPA) and light exposure were measured using a tri-axial accelerometer with an ambient light sensor during the summer. Multiple linear regression models examined associations between average daily light exposure, sedentary time and time in MVPA. Models were repeated investigating weekdays and weekend days separately. Analyses were adjusted for pre-specified covariables, including age, sex, device wear time, ethnic group, school and body fat.
