Evidence for Genetic Influences on Sleep Disturbance and Sleep Pattern in Twins

Evidence for genetic influences on sleep disturbance and sleep pattern in twins.

The etiologic role of genotype and environment in sleep pattern (daytime napping, habitual bedtime, and sleep duration) and subjective sleep quality and sleep disturbance was examined using a general population sample of 3,810 adult Australian twin pairs, aged 17-88 years. Genetic differences accounted for at least 33% of the variance in sleep quality and sleep disturbance and 40% of the varian...

Genetic and Environmental Influences on Infant Sleep

BACKGROUND: Sleep duration is attracting increasing attention in relation to chronic disease risk, but few large-scale studies have investigated the determinants of sleep characteristics in early life. In this study we used data from a large, population-based twin study to examine genetic and environmental influences on sleep duration and sleep difficulties in infancy. METHODS: Participants wer...

Sleep Disturbance and Upper-Extremity Disability

  Background: Although upper-extremity disability correlates with psychosocial aspects of illness the association with sleep disturbance in upper extremity disability is less certain. To evaluate whether sleep disturbance is associated with upper-extremity disability among patients with upper extremity illness, accounting for sociodemographic, condition-related, and psychosocial factors. Method...
