Sleep quality and risk of cancer: findings from the English longitudinal study of aging.

ABSTRACT: To prospectively examine the association between sleep quality and incident cancer risk in the elderly. A total of 10,036 participants aged ≥50 years free of cancer at baseline from the English Longitudinal Study of Ageing at wave 4 (2008) were included, and followed up until 2016. The primary endpoint was new onset physician-diagnosed cancer.
