New links found between sleep duration, depression

A genetic study of adult twins and a community-based study of adolescents both report novel links between sleep duration and depression. A study of 1,788 twins is the first to demonstrate a gene by environment interaction between self-reported habitual sleep duration and depressive symptoms. Another study of 4,175 individuals between 11 and 17 years of age is the first to document reciprocal effects for major depression and short sleep duration among adolescents using prospective data.http://feeds.sciencedaily.com/~r/sciencedaily/~3/N...
