How do short sleepers use extra waking hours? A compositional analysis of 24-h time-use patterns among children and adolescents.

ABSTRACT:

Background

To examine compositional associations between short sleep duration and sedentary behavior (SB), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) among children and adolescents.

Methods

Multi-day 24-h data on sleep, SB, LPA and MVPA were collected using accelerometers among 343 children (8-13 years old) and 316 adolescents (14-18 years old). Children and adolescents with sleep duration of < 9 and < 8 h, respectively, were classified as short sleepers. Robust compositional regression analysis was used to examine the associations between short sleep duration and the waking-time composition.

Results

Seventy-one percent of children and 75.3% of adolescents were classified as short sleepers. In children, being a short sleeper was as
