Epidemiological studies of insomnia in the general population have reported high prevalence rates.
However, few have applied diagnostic criteria from existing classification systems.
Consequently, it is not possible to determine whether subjects suffered from a sleep disorder or whether the insomnia constituted a symptom of a mental disorder.
Insomnia and its relationship with other mental disorders was investigated in the general population using DSM-IV criteria.
A representative sample of 5622 subjects from the French population were interviewed about their sleep habits over the telephone by lay interviewers.
The course and content of interviews were customized by means of the Sleep-Eval knowledge-based system.
A total of 18.6% of the sample reported insomnia complaints.
The presence of insomnia complaints, lasting for at least one month with daytime repercussions was found for 12.7% ofthe sample.
Subsequently, subjects were classified according to the Sleep Disorder decision-making process proposed by the DSM-IV classification, but without the recourse of polysomnographic recordings.
Specific sleep disorder diagnoses were given for 5.6% of the sample, mostly as insomnia related to another mental disorder ; primary insomnia was given for 1.3% of the sample.
Primary mental disorder diagnoses were supplied for 8.4% of the sample, mostly as generalized anxiety disorder. (...)
