Genetic and Environmental Influences on Sleep, Pain, and Depression Symptoms in a Community Sample of Twins

Conclusions: The link between sleep quality, pain, and depression was primarily explained by shared genetic influences. The genetic factors influencing sleep quality and pain were highly correlated even when accounting for depression. Findings support the hypothesis of a genetic link between depression and pain as well as potential causality for the association of sleep quality with pain and depression.
