Prevalence and consequences of insomnia disorders in the general population of Italy

Prevalence of causes of insomnia in primary care: a cross-sectional study

“…The choice of questions was based on some of the community work of Ohayon and Smirne 8 and through discussion among the clinicians involved in the study. A screening questionnaire for sleep disorders was included in the study; this was administered immediately prior to ASQV1.…”

“…One study by Ohayon is the closest to the current study but, as it is community based, the prevalences of conditions are likely to be different from a primary care setting. 8 Ohayon found that mental disorders were contributors to insomnia making up about 10% of the sleep disordered population in Italy. 8 The general (physical) health issues were much lower at 0.5%, which differs majorly from primary care, as would be expected.…”
