Abstract

Most studies show a steep increase in asthma prevalence in the last decades, although few studies had applied the same methodology. Recent reports point out the possibility that the epidemic has come to an end. We have studied the prevalence of asthma in a very large sample of children, repeating the study eight years apart.Repeated cross-sectional studies using the International Study of Asthma and Allergies in Childhood (ISAAC) protocol in a sample of Spanish schoolchildren 6–7 (parent-reported) and 13–14 (self-reported) years old in 1994–95 (phase I) and 2002–2003 (phase III). The number of participants was 42 417 in phase I and 42 813 in phase III. The participation rate was over 87% (13–14 years) and 70% (6–7 years).The prevalence of wheezing in the previous year in children aged 13–14 years was 9.0 and 9.3% for boys and 9.6 and 9.2% for girls for phases I and III, respectively. Children 6–7 years of age showed a substantial increase in wheezing in the previous year (7.0 and 10.7% for boys and 5.3 and 8.2% for girls). Other symptoms and severity indexes followed the same patterns.In the last 8 years, the prevalence of asthma has not changed in 13–14-year-old Spanish children but has increased substantially in 6–7-year olds.

Abstract

The prevalence of atopic dermatitis (AD), a chronic skin disease, has increased substantially in recent decades, and different factors have been implicated in its etiology. Although dietary habits are being investigated, few conclusive findings have been reported. Nevertheless, increased consumption of polyunsaturated fatty acids (PUFA) and a diet poor in antioxidants have been related to AD.The objectives of this study were to investigate the association between AD, the intake of different foods, and the effect of a Mediterranean diet among Spanish schoolchildren aged 6 to 7.We performed a cross-sectional study with 20 106 schoolchildren aged 6-7 years from 10 different areas of Spain. The participation rate was 76.50%. The prevalence of AD was assessed using the International Study of Asthma and Allergies in Childhood questionnaire and the criteria of the Spanish Academy of Dermatology. To calculate the Mediterranean diet score, we classified food into 2 groups: Mediterranean food, including fruit, seafood, vegetables, pulses, cereals, pasta, rice, and potatoes; and non-Mediterranean food, including meat, milk, and fast food.Milk was negatively associated with AD. Butter and nuts also were negatively associated, although statistical significance was only reached when these foods were consumed 3 or more times a week.We found no association between the Mediterranean diet score and AD and a positive association between AD and obesity.

Abstract

BACKGROUND The Global Asthma Network (GAN), by using the International Study of Asthma and Allergies in Childhood (ISAAC) methodology, has updated trends in prevalence of symptoms of childhood allergic diseases, including non-infective rhinitis and conjunctivitis ("rhinoconjunctivitis") which is reported here. METHODS Prevalence and severity of rhinoconjunctivitis were assessed by questionnaire among schoolchildren in GAN Phase I and ISAAC Phases I and III surveys 15-23 years apart. Absolute rates of change in prevalence were estimated for each centre and modelled by multi-level linear regression to compare trends by age group, time period and per-capita national income. RESULTS 27 GAN centres in 14 countries surveyed 74,361 13-14-year-olds ("adolescents") and 45,434 6-7-year-olds ("children"), with average response proportions of 90% and 79% respectively. Many centres showed highly significant (p
