title: [Long-term disease in Danish children reported by the parents].
abstract: BACKGROUND
  The aim of this study was to report the prevalence and nature of long-term diseases and their consequences in children under the age of 16 in Denmark, and to identify the socio-demographic determinants of disease.
  
  
  METHODS
  Parents and stepparents participating in the Danish Health and Morbidity Survey, 2000, were interviewed at home about long-term diseases, including impairments and sequelae after injury and disease, in children under the age of 16 living at home. Answers were given for 7,670 children, and diseases were coded according to ICD-10 by two doctors. Logistic regression analysis was used to identify the determinants and consequences of disease.
  
  
  RESULTS
  A total of 16.2% of children had one or more long-term diseases, boys (17.5%) more frequently than girls (14.8%). The prevalence increased through the first six years of life. A social gradient was seen: children of parents with low socioeconomic status or with little education had a higher prevalence. The most frequent disease was asthma (4.9%). Also frequent were congenital disorders (1.6%), otitis media (1.4%) and hearing impairment (0.6%). Children with long-term disease suffered more frequently than others from poor health in general, recent sick leave and poor thriving.
  
  
  CONCLUSIONS
  The figures for long-term disease reported by the parents participating in the study were in accordance with what was found in earlier studies, but stigmatising and less severe diseases, as well as periodically recurring diseases, were probably underreported. Attention should be paid to the high prevalence of asthma, to the poorer thriving and to the general health status of children with long-term disease, and to the social inequality in children's health.
