• Resumen

  • Background Atopic eczema affects 5�10% of the Spanish paediatric population, and has increased in frequency over the last few decades, probably due to changes in the environment and lifestyle. Phase II of the ISAAC (International Study of Asthma and Allergies in Childhood) uses a standardised methodology to establish the prevalence of allergic disorders and factors linked to them in each centre.

    Objectives To assess the prevalence and severity of atopic eczema, and to establish factors linked to atopic eczema in 10�11 year-old school children in the city of Almeria (South-East coast of Spain).

    Material and methods An ecological study was carried out as part of ISAAC II, using homologated questionnaires and allergic tests in 1143 schoolchildren. Statistic association was assessed by means of ?2 test, and then logistic regression analysis was performed with the most significant variables from the univariant analysis.

    Results The prevalence of atopic eczema was 11.4%. The risk factors found in the multiple logistic regression analysis were: personal antecedents of severe asthma (OR 19 CI 95% 1.35�266) and severe rhinitis (OR 7.7 CI 95% 1.79�33), fungi in bedroom during the first year of life (OR 4.2 CI 95% 1.17�15.1) and atopic eczema in one parent (OR 5.2 CI 95% 2.69�10.1).

    Conclusions The prevalence of atopic eczema is similar to that found in other studies within ISAAC Phase I. The most important risk factors for atopic eczema are family and personal history of other atopic diseases and the presence of fungi in the home.
