Abstract

Abstract Introduction Delayed sleep phase syndrome (DSPS) is a circadian rhythm sleep disorder with a definition of delayed night sleep by two or more hours beyond the socially acceptable or conventional bedtime. The general reported prevalence of DSPS is 7% to 16%. However, there is no previous study which assess DSPS prevalence in Oman or nearby regions. This study aimed to assess the prevalence of DSPS among Omani population and to establish a connection between demographics and DSPS. Methods This community-based study included 186 subjects aged from 18 to 64 who had one week of actigraphy records along with their demographical data in Sultan Qaboos University hospital. Results Among the 186, 19 (10.2%) subjects were identified of having DSPS in weekdays, and 15 (11.4%) subjects have DSPS in weekends. The results indicated that marital status had significant relation (P=0.02) more with unmarried group (62.50%, N=10). No significant relationship was found between DSPS and age, gender, BMI, education and employment status in either weekdays or weekends (P>0.05) Conclusion A consistent rates of DSPS was found among Omanis which are 10.2% in weekdays and 11.4% in weekends. Also, DSPS have significantly higher rates among unmarried subjects in weekdays. Further studies in DSPS are needed to assess risk factors and possible health impacts.
