  1. How a general population perceives its sleep and how this relates to the complaint of insomnia.

    Article - En anglais

    The traditional indicators of insomnia (i.e. difficulty initiating sleep, difficulty maintaining sleep, nonrestorative sleep, early morning awakening) were assessed in a representative sample of 1,722 French-speaking Montrealers (Canada) aged 15 to 100 years.

    These subjects were interviewed over the telephone (81.3% of contacted sample) by means of the Sleep-Eval software.

    Subjects were classified as either satisfied or dissatisfied with quality of sleep (SQS or DQS), with or without insomnia indicators (+I or - I).

    Sociodemographics, sleep-wake schedules, evening activities, medication intake, recent medical consultations, and social life were also investigated.

    DQS subjects composed 17.8% of the population (DQS+I : 11.2% ; DQS-I : 6.5%), and 21.7% of subjects were classified as either DQS+I or SQS+I. Overall, 3.8% of subjects reported using a sleep-enhancing medication.

    Nonrestorative sleep did not significantly distinguish SQS and DQS subjects.

    The complaint of nonrestorative sleep is not a useful indicator of insomnia, despite its inclusion in all medical classifications.

    DQS-I and SQS+I subjects defy traditional classifications.

    A better understanding of sleep complaints and more accurate classifications will help physicians identify patients with insomnia and meet their needs more appropriately.
