Sleep deficiency at baseline (inadequate sleep quality and/or insufficient sleep duration) was defined as having ≥ 1 of the following components: Wake after Sleep Onset (WASO) > 45 minutes per main sleep period (measured using wrist actigraphy and suggestive of insomnia), self-reported sleep insufficiency (never or rarely feeling rested upon waking) and/or mean actigraphically-measured total sleep time < 6.5 hours per 24 hours.
