The objective of this study was to update and analyze tuberculosis (TB) mortality data in the European Union between 2000 and 2010 separately for men and women and try to detect if there have been any changes in trends in each country and the association with the economic situation and inequalities.

Se desconoce la evolución temporal de la prevalencia de asma descrita en el ISAAC (International Study of Asthma and Allergies in Childhood) en 2002 o si las diferencias geográficas o por edades se mantienen en España.

Objective. To estimate the risk factor for symptoms of allergic rhinitis in adolescents in Castellón, Spain. Methods. A cross-sectional population based study of Phase III of the International Study of Asthma and Allergies in Childhood (ISAAC) conducted in 2002 among adolescents from 13-14 years of age. The ISAAC questionnaire was used to define cases of allergic rhinitis. Logistic regression models were used to estimate odds ratio (OR) and their 95% confidence intervals (95%CI). Results. Participation was 66.8% (3 995 adolescents of the 5 981 total). The prevalence of rhinoconjunctivitis symptoms in the last 12 months was 16.5% and the prevalence of nasal allergy at some point was 7.4%. Logistic regression showed that rhinoconjunctivitis was associated with being female (OR = 1.63; 95%CI: 1.33-2.00); a mother who smokes in the home (OR = 1.32; 95%CI: 1.08-1.63); a history of sinusitis (OR = 2.02; 95%CI: 1.51-2.70); and living on a street with heavy truck traffic (OR = 1.58; 95%CI: 1.02-2.44). Likewise, nasal allergy was associated with a family history of allergic rhinitis (OR = 2.62; 95%CI: 1.90-3.63); a history of sinusitis (OR = 2.65; 95% CI: 1.77-3.96); a history of bronchitis (OR = 1.68; 95%CI: 1.19-2.36); and social class, with a steady decline when comparing higher classes to lower classes. Conclusions. Various environmental risk factors were associated with the symptoms of nasal allergies, which points to the importance of implementing specific preventive measures.
