Conditions: Hypertension, Poor Sleep Quality, Insomnia, Arterial Stiffness
Interventions: Behavioral: Cognitive-Behavioural Therapy for Insomnia (CBT-I), Passive sleep education
Countries: Portugal
This prospective, parallel-group randomised controlled trial evaluates whether cognitive-behavioural therapy for insomnia (CBT-I) improves arterial function and psychological and cognitive outcomes in hypertensive patients with poor sleep quality. Adults aged 18-70 with controlled hypertension and poor baseline sleep quality (sleep efficiency \<=85%) are randomised 1:1 to CBT-I (four weekly 60-minute sessions) or passive sleep education. The primary outcomes are change from baseline in pulse wave velocity and central arterial pressure at 12 months. Secondary outcomes include blood pressure, depressive symptoms, perceived stress, cognitive complaints, and sleep quality, assessed at baseline, 1, 6, and 12 months.
