PAC-SA, María Rosario et al. Risk factors for symptoms of allergic rhinitis in adolescents in Castellón, Spain. Rev Panam Salud Publica [online]. 2008, vol.23, n.5, pp. 333-340. ISSN 1020-4989. http://dx.doi.org/10.1590/S1020-49892008000500005.
OBJECTIVES: 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.
