title: Epidemiology of analgesic use: a gender perspective.
abstract: OBJECTIVE
  Women consistently report significantly more frequent analgesic use in epidemiological studies. The aim of this study was to analyse the influence of medical and non-medical factors on the difference in use of analgesics between women and men from a population perspective.
  
  
  METHODS
  Cross-sectional survey. Postal questionnaires were sent to a random sample of the general population in the country of Uppland, Sweden (5404 answered the questionnaire, response rate: 68%).
  
  
  RESULTS
  34.8% of the women and 21.4% of the men had used analgesics during the two week recall period (Odds Ratio = 1.96). Social structure, social status, marital status, educational level, economic situation, lifestyle, attitudes toward drugs, medication knowledge and self-care orientation were of minor importance for the difference in use between women and men. Difference in prevalence of various types of pain and ache and the degree of pain experienced were the most influential factors affecting the difference in use. However, when all factors were analysed there remained a substantial difference in use between women and men (OR = 1.39, CI (95%) 1.20 to 1.60).
  
  
  CONCLUSIONS
  In the population, women use analgesics much more frequently than men. Consequently women may be at greater risk for adverse effects and dependency. Some of the gender difference is explained by the greater frequency of pain conditions among women, but a significant difference in use still remains to be explained.
