Objectives: The aim of this study was to determine the prevalence of insomnia among the Saudi adult population. Study design: A cross-sectional insomnia survey was conducted at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia. The presence of insomnia was defined by difficulty initiating sleep, early morning awakening, or frequent awakening, in addition to the second-day effect in the form of fatigue, tiredness, or changes in the mode because of lack of sleep. Results: The crude prevalence of insomnia was 77.7% (95% CI = 75.9–79.5%). The gender-adjusted prevalence of insomnia was higher for females, 88.7% (95% CI = 86.4–90.7%) than for males, 70.4% (95% CI = 67.8–72.9%), p-value =.001. The age-adjusted prevalence of insomnia was higher for the elderly, 93.7% (95% CI = 90.6–96.0%) than for the middle aged, 79.8% (95% CI = 77.4–82.1%), or for the young group, 64.2% (95% CI = 59.9–68.4%), p-value =.001. The Chi-square analyses revealed that (1) being elderly, widowed/divorced, females, or housewives, (2) having a lack of education, and (3) excessive tea consumption were significantly associated with elevated risks for insomnia (p-values <.05). Conclusions: Insomnia is most prevalent among Saudi females and the elderly Saudi population.
