Heritability of siesta and night-time sleep as continuously assessed by a circadian-related integrated measure.

摘要: Siesta is a relevant aspect of sleep due to its posited relationship with health or cognitive function. However, unlike night-time sleep, studies about daytime-sleep determinants and characteristics are scarce, the genetic/environmental structure siesta still unknown. Our aim was explore relative contribution genetic environmental factors variation in sleep-wake rhythm, measured by continuous assessment temperature-activity-position (TAP), which allows for diurnal analysis. The sample comprised 53 pairs female twins (28 MZ 25 DZ), selected from Murcia Twin Register. Mean age participants 52 (SD: 6.03). Zygosity determined DNA. We conducted separate univariate analyses study sources variance daytime parameters. About 60% reported take at least once week. Heritability taking duration 65 61% respectively. Other parameters obtained TAP showed heritability estimates between 36 69%, suggesting impact on rhythm. This first investigate siesta. By using TAP, we introduce novel approach characteristics.
