[Current prevalence of asthma in schoolchildren in San Sebastián (Spain)]

[Cost of childhood asthma in Spain: a cost evaluation model based on the prevalence]

INTRODUCTION

Asthma is the most common chronic disease in childhood, reduces the quality of life of children and their families, and produces high social and health care costs. In Spain, the cost of managing paediatric asthma is unknown.

OBJECTIVE

To estimate the cost of managing paediatric asthma in Spain and to examine its variability depending on asthma severity.

PATIENTS AND METHODS

The cost of asthma in children under 16 years in 2008 was estimated by building a costs assessment model including the factors that influence the cost of asthma in children: prevalence, distribution of disease severity, age, frequency of resources use depending on severity, and the cost of each resource. A sensitivity analysis was conducted to evaluate the underlying uncertainty depending on the variability of the estimators of resource use, the unit cost of each resource, and the prevalence.

RESULTS

According to the model, the total cost of paediatric asthma in Spain is around 532 million euros, with a range of 392 to 693 million euros. Direct costs (health care costs) represent 60% of the total costs, and indirect costs (carer time), 40%. The mean annual cost per child with asthma is 1,149 euros, ranging from 403 euros for the mildest category of the disease to 5,380 euros for the most severe.

CONCLUSIONS

The cost of paediatric asthma in Spain is very high and depends on disease severity. Although the most important costs are for the health care system, indirect costs are not negligible.

[Prevalence of asthma and rhinitis symptoms in A Coruña (Spain)]

INTRODUCTION

The prevalence of asthma and rhinitis is high in childhood and has been increasing in the last few years. In both diseases underdiagnosis is frequent.

OBJECTIVE

To asses the prevalence of asthma and rhinitis symptoms in childhood.

MATERIAL AND METHODS

We performed a cross-sectional study using a written questionnaire, following the methodology of the International Study of Asthma and Allergies in Childhood (ISAAC), on the prevalence of symptoms of asthma and rhinitis in La Coruña.

RESULTS

A total of 3017 boys and girls aged 6-7 years old (response rate 73.9 %) and 2981 boys and girls aged 13-14 years old (response rate 93.6 %) were included. The prevalence of "wheezing at some time" was 25.3 % in adolescents aged 13-14 years old and was 37.2 % in children aged 6-7 years. The prevalence of "asthma at some time" was 18.5 % in adolescents and 13.7 % in children. The prevalence of "rhinitis at some time" was 30.4 % in the group aged 6-7 years and 47.3 % in the group of adolescents. The prevalence of rhinitis was highest in autumn.

CONCLUSIONS

The prevalence of asthma and rhinitis is high in our population and is higher than that observed in most Spanish populations studied.
