title: [Prevalence of the use of hypnotics and sedatives among the working population and associated work-related stress factors].
abstract: OBJECTIVE
  To explore the prevalence of the use of hypnotics and sedatives in a sample of the Spanish working population and to examine its association with certain work-related stress factors.
  
  
  METHODS
  Using data from the 2007 Spanish Household Survey on Alcohol and Drugs (Encuesta Domiciliaria sobre Alcohol y Drogas en España [EDADES]), we analyzed the distribution of the use of hypnotics and sedatives in the previous month in the working population aged 16 to 64 years old (n=13,005). Associations with exposure to certain work-related stress factors (noxious working environment, precariousness, workload, and social support) were examined using logistic regression modelling.
  
  
  RESULTS
  The prevalence of the use of hypnotics and sedatives among women in the previous month doubled that of men (6.5% and 3.3%, respectively), while use among the oldest age group was twice that of the youngest group in both sexes (10.2% in women and 5.5% in men older than 45 years), and was four times higher among those reporting poor health (18.9% in women and 11% in men). Concerning work-related stress, exposure to moderate (OR: 1.96; 95%CI: 1.31-2.92) and high (OR: 1.95; 95%CI: 1.14-3.34) levels of precariousness in men and moderate levels in women (OR: 1.43; 95%CI: 1.03-1.99) was associated with the use of hypnotics and sedatives.
  
  
  CONCLUSIONS
  The prevalence of the use of hypnotics and sedatives was high in women and in workers older than 45 years. Further research is needed on the relationship between the use of hypnotics and sedatives and workers' health, and on the role that work-related stress factors play in this association.
