ABSTRACT
Background: Sleep problems are one of the main health issues raised by families. Therefore, we aimed to evaluate the sleep problems of pre-school children in Iran. Methods: Five hundred and seventy-nine children aged 3–6 years were randomly recruited from 15 kindergartens in the city of Qazvin in Iran. The Iranian version of BEARS (Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep and Snoring) and the Children’s Sleep Habits questionnaire (CSHQ) were completed by interviewers. Data analysis was performed using SPSS version 19. The data were analysed with a Student’s t-test, chi-square and Fisher’s exact tests. A P value 0.05). Conclusion: The children had sleep-related problems, including a late bedtime, delayed sleep onset, daytime sleepiness, midnight awakening, sleep-disordered breathing, and snoring. Sharing a room was very common among the Iranian children.
