High Blood Pressure Not Associated With Insomnia

Difficulty falling asleep may be associated with a lower risk of hypertension than researchers once believed. Researchers from the University of Kentucky proposed the hypothesis that insomnia would predict hypertension, particularly among African-Americans. Data were analyzed from 1,419 older individuals with a mean age of 73.4 years who were not hypertensive at baseline. Researchers found that difficulty falling asleep, alone or in combination with other sleep complaints, predicted a significantly reduced risk of incident hypertension for men who were not African-American over a 6-year period of follow up. Furthermore, insomnia complaints did not predict hypertension in women or in African-Americans, although there may not have been enough power to show a significant association for African-Americans.
