Socioeconomic Inequalities and Sleep duration; Evidence from a large Kurdish Cohort Study in Iran
Background
Sleep as an essential physiological need plays an important role in the human health. The aim of this study was to examine socioeconomic inequality in sleep duration among Kurdish people in Western of Iran.
Methods
The study used data of 10058 participants which from Ravansar Non-Communicable Disease (RaNCD) cohort study which recruited a sample of Kurdish adults in Kermanshah, west of Iran. The Slope Index of Inequality (SII) as well as the Relative Index of Inequality (RII) with 95% confidence intervals was calculated to determine socioeconomic inequality in sleep duration.
Results
There was 0.64 (95% CI: 0.55, 0.74) hour difference in the mean of sleep duration in favor of the rich group. Moreover, the mean of sleep duration in the people with lowest socioeconomic status quintile was 5% lower than those in the highest socioeconomic status quintile (RII= 0.95, 95% CI: 0.93, 0.96). For all analyses, observed inequalities were nearly equal by gender.
Conclusion
Our results demonstrated an important role for inequality in differential sleep duration in an Iranian Kurdish population. Improving the socioeconomic status of the general population especially people with low socioeconomic status may be useful in tackling the observed sleep issues.
