Sleep Hygiene Education and Blood Pressure Control in Essential Hypertension in Primary Care

Plain-language summary

This randomized controlled trial evaluated the effect of a brief sleep hygiene education program on sleep quality and blood pressure in adults with essential hypertension attending a family practice center in southern Türkiye. Poor sleep quality is common in patients with hypertension and may contribute to inadequate blood pressure control and increased cardiovascular risk. In this single-centre trial, 138 adult patients with physician-diagnosed essential hypertension were randomly assigned to an intervention group or a control group. The intervention group received a 10-15 minute face-to-face sleep hygiene education session delivered by a family physician, together with a printed brochure summarising key sleep hygiene recommendations. Participants were asked to keep a sleep diary for 8 weeks and were contacted by telephone at weeks 2, 4, and 6 to reinforce the recommendations. The control group received usual medical care for hypertension without additional education or follow-up contacts. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and office blood pressure was measured at baseline and after 8 weeks in both groups. The primary objective was to determine whether sleep hygiene education improves sleep quality; secondary objectives were to evaluate the effects of the intervention on systolic and diastolic blood pressure compared with usual care.
