Sleep duration and risk of stroke and coronary heart disease: a 9-year community-based prospective study of 0.5 million Chinese adults.

ABSTRACT:

Background

There is uncertainty about the optimum sleep duration for risk of different subtypes of stroke and ischaemic heart disease.

Methods

The present analyses involved 409,156 adults in the China Kadoorie Biobank study without a prior history of coronary heart disease or stroke or insomnia symptoms.
