Females (OR=2.5; 95%CI: 2.1-3.1), moderate economic status (OR=1.2; 95%CI: 1.0-1.5) and smoking (OR=1.5; 95%CI: 1.1-1.9) were positively associated with poor sleep quality.Conclusion: The result of our study showed that women had poorer sleep quality than men and smoking is a risk factor for poor sleep quality.
