[BDSP. Notice produite par INIST-CNRS R0xH88lo. Diffusion soumise à autorisation]. Background Daytime napping is associated with elevated risk of all-cause mortality in the elderly. However, the association with cardiovascular disease (CVD) risk is inconsistent. Methods From 1988 to 1990, a total of 67 129 Japanese non-workers or daytime workers (27755 men and 39374 women) aged 40-79 years, without a history of stroke, heart disease or cancer, completed a lifestyle questionnaire. They were followed for mortality until the end of 2003.

After adjustment for possible confounders, subjects with a daytime napping habit had elevated hazard ratios (HRs) for mortality from all causes [HR 1.19,95% confidence interval (CI) 1.14-1.24, P
