Beskrivelse
Inclusion Criteria:
- Signed written informed consent
- ≥18 years on entry to study
- Average automated Systolic Blood Pressure (SBP) monitor readings between 130 - 160 mmHg with average automated Diastolic Blood Pressure(DBP) monitor readings <110 mmHg on three occasions, measured in a valid standardized manner while seated, or average Ambulatory Blood Pressure Monitor (ABPM) SBP reading between 130-160 mmHg with average DBP reading <110 mmHg.
- Self-reported difficulty getting to sleep (defined as usually taking more than 30 mins to get to sleep), and/or staying asleep (usually waking up more than once per night) for at least 3 months duration

Eksperimentel: Online Sleep Education
The sleep intervention is a multi-component online intervention consisting of sleep information and sleep hygiene education, along with behavioural and cognitive components.
|
|
|
Ingen indgriben: Usual CV care
Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.

Systolic Blood Pressure
Tidsramme: 8 weeks

To determine if the addition of a multi-component, online, sleep intervention to usual care (standard CV risk factor education), results in a greater reduction in mean 24-hr systolic blood pressure in patients with hypertension and poor sleep quality, compared to usual care alone, over an 8-week period.
