Self-reported napping and duration and quality of sleep in the lifestyle interventions and independence for elders pilot study.

ABSTRACT:

To determine the prevalence of self-reported napping and its association with subjective nighttime sleep duration and quality, as measured according to sleep-onset latency and sleep efficiency.

Design

Cross-sectional study.
