Abstract excerpt

STUDY OBJECTIVES: Our aim was to estimate heritability in phenotypic insomnia and the association between insomnia and mortality. DESIGN: Representative follow-up study. PARTICIPANTS: 1990 survey of the Finnish Twin Cohort (N = 12502 adults; 1554 monozygotic and 2991 dizygotic twin pairs). MEASUREMENTS: Current insomnia-related symptoms (insomnia in general, difficulty in initiating sleep, sleep latency,...
