Results from a recent study, cited in the journal SLEEP, shed some interesting light on sleep, physical activity, environment and childhood depression.
“We reported in a study previously, that genes were the most important factor in explaining the association between sleep problems and depression in eight year olds,” said lead author Alice M. Gregory, senior lecturer in the department of psychology at Goldsmiths College in London.
“However, when we examined this issue at age 10, we found that genes were less important in explaining the association and that environmental influences had become more important. This could be because environmental experiences are becoming more relevant as children grow older and could therefore play a role in both sleep problems and depression.”
Could it also be that the reduction or elimination of free play or recess in schools is contributing to increased depression in children?
