Background: Sleep is one of our basic needs. It is important for our physical, intellectual and emotional health, although highly prevalent; sleep disorders are generally under diagnosed in the adult population. This can possibly be overcome by the use of short sleep questionnaires, which could work as a screening device for sleep disorders. Aim: This study aimed to screen sleep disorders and evaluate main sleep disorders (Insomnia, Obstructive sleep apnea disorder, rapid eye movement behavior disorder and excessive daytime sleepiness) among healthy individuals. Participants & Method: This study was conducted on 2000 healthy persons; their sleep–wake habits were assessed by means of a clinical interview and validated scales: Insomnia Symptom Questionnaire (ISQ), REM sleep behavior disorder questionnaire (RBDQ-HK) the Sleep Apnea scale of Sleep Disorders Questionnaire (SA-SDQ) and Epworth Sleepiness Scale (ESS). Results: The overall incidence of sleep disorders in healthy subjects was 35.10%; the incidence of insomnia was 30.05%, rapid eye movement behavior disorder was 14.9%, sleep apnea was 30.1% and excessive daytime sleepiness was 14.6%. A statistically significant difference was found as regards age in obstructive sleep apnea and excessive daytime sleepiness, females were significantly more prone to experience insomnia than males; highly statistical significant difference was found between insomnia and other sleep disorders, more over high statistical significant difference was found between rapid eye movement behavior disorder and excessive daytime sleepiness. Conclusion: Sleep disorders are common health problems in healthy individuals and should be taken into consideration in health evaluation programs.
