Brief Summary

Sleep is an essential component of good physical and mental health. Previous studies have reported that poor quality sleep is associated with an increased risk of hypertension, stroke and cardiovascular disease (CVD). Hypertension is the most common and important risk factor for CVD, and even modest reductions in blood pressure result in significant reductions in stroke and myocardial infarction. In this randomised trial, the investigators aim to evaluate whether a simple, multi-component, online sleep intervention reduces blood pressure in patients with essential hypertension.

Outcome Measures

Primary Outcomes (1)

  • Systolic Blood Pressure

    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.

    8 weeks

Secondary Outcomes (6)

  • Diastolic Outcome Measure

    8 weeks

  • Sleep efficiency

    8 weeks

  • Sleep onset latency

    8 weeks

  • PSQI

  • SCI

  • +1 more secondary outcomes

Other Outcomes (21)

  • Body Mass Index

  • Plasma lipoproteins

    8 weeks

  • Plasma HbA1c

    8 weeks

  • +18 more other outcomes

Study Arms (2)

Online Sleep Education

EXPERIMENTAL

The sleep intervention is a multi-component online intervention consisting of sleep information and sleep hygiene education, along with behavioural and cognitive components.

Behavioral: Online Sleep Education

Usual CV care

NO INTERVENTION

Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.

Interventions

Online Sleep Education
