A twin-study of genetic contributions to morningness-eveningness and depression.

Chronobiology international - 1 Apr 2015

Abstract excerpt

Circadian rhythms are associated with the preference for sleep-wake timing, also known as morningness-eveningness (ME). Both circadian rhythms and ME are influenced by genetic factors. Studies show an association between eveningness and depression. This study investigates the heritability of ME and whether ME and depression share common genetic influences. Study participants (n = 1237) were from the Vietnam Era...
