Abstract

In a prospective study of 23 995 Japanese women, short sleep duration was associated with higher risk of breast cancer (143 cases), compared with women who slept 7 h per day, the multivariate hazard ratio of those who slept ≤6 h per day was 1.62 (95% confidence interval: 1.05-2.50; P for trend=0.03).
