Insufficient sleep is a risk factor for hypertension in adults, and children with obstructive sleep apnea have higher diastolic blood pressure (BP) than do primary snorers (without apnea). To examine whether poor-quality or insufficient sleep is associated with abnormal BP, investigators analyzed data from 238 healthy adolescents who did not have sleep apnea (mean age, 14 years; about 50% male, black, and born prematurely) who were enrolled in the Cleveland Children’s Sleep and Health Study.
Participants underwent 5- to 7-day wrist actigraphy to measure sleep patterns at home and overnight polysomnography in a clinical research unit, during which nine BP readings were obtained. Low sleep efficiency was defined as ≤85% time spent sleeping whi…
