Abstract
Introduction

Atopic dermatitis is a common and increasingly prevalent disorder. The International Study of Asthma and Allergies in Childhood (ISAAC) made a major contribution to the understanding of its epidemiology.

Objectives

The aim of this study was to estimate the prevalence and severity of atopic dermatitis in a representative sample of 6 to 7-year-old and 13 to 14-year-old children from the province of Granada, Spain, using validated questionnaires and to analyze potential differences between coastal and inland regions.

Material and methods

This was a descriptive cross-sectional observational study of schoolchildren from Granada, Spain, aged between 6 and 7 years and 13 and 14 years. The main instrument was the core questionnaire module for dermatitis used in phase I of the ISAAC study.

Results

Statistically significant differences were found in Granada schoolchildren aged 6 to 7 years in terms of prevalence of dermatitis at some time, typical site, resolution in the last 12 months, and diagnosis of atopic dermatis. No significant differences were observed on comparison of the prevalence of atopic dermatitis between coastal and inland populations. Finally, in the comparison of schoolchildren aged 6 to 7 years, we observed almost significant differences for dermatitis at some time, resolution in the last 12 months, and diagnosis of atopic dermatitis on considering age and geographic location of the study population.

Conclusions

The prevalence of atopic dermatitis is similar in the coastal population and the provincial capital. In terms of clinical symptoms and disease course, atopic dermatitis tends to stabilize with age.

Resumen
Introducción

La dermatitis atópica (DA) es una enfermedad frecuente cuya prevalencia se ha incrementado progresivamente. En el conocimiento sobre su epidemiología ha desempeñado un papel muy importante el estudio ISAAC (International Study of Asthma and Allergy in Childhood).

Objetivos

Estimar la prevalencia y gravedad de la DA en niños de 6-7 y 13-14 años de la provincia de Granada a partir de una muestra representativa mediante encuestas validadas y analizar si existen diferencias, comparando las zonas costeras con el interior.

Material y métodos

Diseño observacional descriptivo transversal de base escolar. La población de estudio fue el alumnado de 6-7 y 13-14 años de Granada. Como instrumento de medición se utilizó el «cuestionario central para dermatitis» que el estudio ISAAC empleó en su primera fase.

Resultados

Respecto a la prevalencia de síntomas en escolares granadinos según edad, se observaron diferencias estadísticamente significativas en escolares de 6-7 años en cuanto a «prevalencia de dermatitis alguna vez», «localización típica», «desaparición en los últimos 12 meses» y «diagnóstico de DA». Respecto a la prevalencia según zona geográfica, no hemos encontrado diferencias estadísticamente significativas. Finalmente, objetivamos diferencias casi significativas para la población de 6-7 años en la prevalencia de «dermatitis alguna vez», «desaparición en los últimos 12 meses» y «diagnóstico de DA» al relacionar los síntomas con la edad y la zona geográfica de la población de estudio.

Conclusiones

La población costera y la de la capital ofrecen una prevalencia similar. Bajo una perspectiva clíni-co-evolutiva la dermatitis atópica tiene tendencia a estabilizarse con la edad.
