Abstract

Introduction: Arterial hypertension is responsible for large part of the cardiovascular disease load. However, the role of sleep in its aetiology remains controversial. Objective: To determine the relationship between sleep attributes and the change in blood pressure. Methods: A prospective cohort study was carried out on a community basis in young adults asymptomatic for cardiovascular disease, followed up for 12.4 years. At baseline, sociodemographic and behavioural factors were determined. At the same, time nocturnal sleep was characterised in terms of quality, duration and presence of snoring. Standardised anthropometric indices and blood pressure were measured. Arterial hypertension was defined as a report of anti-hypertension treatment or blood pressure figures ≥140/90 mm Hg. Results: A total of 1,032 participants were prospectively evaluated (mean age 36.8 years, 64% males; at baseline). The incidence of arterial hypertension was 15.1% (95% CI: 12.8 – 17. 4), with evidence of a higher risk in snorers, with a subsequent reduction on adjusting for adiposity (P>.05). A gradient was observed between the duration of sleep and the change in systolic/diastolic arterial pressure (2.2/1.3 mmHg in those who reported 6-8 hours/day, and 2.7/1.6 mmHg in those who reported > 8 hours/day, compared to < 6 horas/day). Neither the subjective quality of the sleep nor the report of a siesta was associated with the blood pressure. Conclusion: The results suggest that the prolonged duration of sleep could increase blood pressure in the population.
