Results show that the genetic influences on insomnia symptoms in adults were substantial and largely stable over time while differing significantly by sex.
In the longitudinal model, the estimated heritability of insomnia was 59 percent for females and 38 percent for males."
"This study indicates that genes may play a larger role in the development of insomnia symptoms for women than for men,
According to the American Academy of Sleep Medicine, transient insomnia symptoms occur in 30 to 35 percent of the population.
Chronic insomnia, which occurs at least three times per week for at least three months, affects about 10 percent of adults.
Insomnia is more common in women than men and involves difficulty falling asleep or staying asleep
Insomnia symptoms were evaluated via self-report questionnaire at two non-overlapping time points. According to the authors, this is the first study to examine the genetic and environmental influences on insomnia symptoms in adults in a longitudinal, representative twin sample.
The authors also noted that in addition to the substantial heritability estimates, unique environmental factors continue to account for a large amount of variance in insomnia symptoms s
