title: Use of six main drug therapeutic groups across educational groups: self-reported survey and prescription records.
abstract: OBJECTIVE
  To assess whether the use of six main therapeutic groups was congruent with the occurrence of related diseases across educational groups.
  
  
  METHODS
  Two data sources were analysed: (i) Interview data from The Danish Health and Morbidity Survey 2000 on a representative sample of the Danish population ages 16 years and above (n = 16,690); (ii) Prescription records linked to a health survey on a representative sample of the population of Funen County 2000-2001 (n = 3,422). The use of six therapeutic main groups (ATC groups A, B, C, M, N and R) and related diseases in educational groups was analysed by indirect standardization. Age and gender standardized prevalence ratios (SPRs) and 95% confidence intervals were calculated on the basis of the total study population.
  
  
  RESULTS
  In general, respondents in the two least educated groups used medicines more frequently and a higher proportion of them reported the related disease than could be expected from indirect standardization. The opposite picture appeared for respondents in the two highest educational groups (SPR < 100). The overall patterns were similar for the six medicine groups, although some of the SPRs were not significant.
  
  
  CONCLUSIONS
  The results show the uneven distribution of disease in the general population. The distribution of medicine use generally followed this pattern, which means that those in the greatest medical need used the most medicine. Hence, individual co-payment for medicine did not seem to be a barrier to access to medicine in any of the educational groups.
