Abstract

STUDY OBJECTIVE:

To examine effect of siesta on mortality.

DESIGN:

A 12 years prospective cohort.

SETTING:

Population sample.

PARTICIPANTS:

Residents of Jerusalem (n=455), 70 year olds.

INTERVENTIONS:

N/A.

RESULTS:

There were more males in the group with the siesta (n=276), 68% and more (16%) past myocardial infarction than those without the siesta, 6% (n=179) p < 0.01. After 12 years 147 subjects died. Survival was 64% in people practicing the siesta, and 74%, who did not p = 0.005. In a Cox proportional hazard model, that included many confounding factors hazard ratio (HR) for mortality was 1.6 95% confidence interval (CI) 1.2-2.7, for those who napped. After exclusion of the 19 subjects who died during the first 2 years of follow-up, the hazard ratio was not materially altered, HR of 1.6 95% CI, 1.0-2.6.

CONCLUSION:

Although causality is not clear, the siesta appears to be a significantly independent mortality predictor.
