link between sleep and CVD-free life expectancy at age 40. Researchers conducted a cohort study to estimate the CVD-free years of life lost for patients with self-reported and clinically diagnosed poor sleep.
Study participants completed a baseline sleep questionnaire. Scores were assigned one of three categories: Healthy sleep (4-5 points), Intermediate sleep (2--3 points) and Poor sleep (0-1 points). Researchers also looked at participants' health records to examine primary care visits, hospital admissions, and sleep disorder prescriptions.
Results found a lower CVD-free life expectancy at age 40 in participants with self-reported poor sleep compared to participants reporting good sleep with a difference of 1.80 years in women and 2.31 years in men.
