Abstract

Objective: To investigate the association between smoking and asthma, and possible associated factors in Brazilian adolescents. Methods: A cross-sectional, national, school-based study with adolescents aged 12–17 years, participants in the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes – ERICA). A total of 66,394 participants answered a self-administered questionnaire with questions about asthma, smoking, lifestyle and sociodemographic variables. Bivariate analysis between Current Asthma (CA) and Severe Asthma (SA) and the other study variables were performed using Chi-squared. Then, the crude and adjusted Prevalence Ratios (PR), and respective 95% Confidence Intervals (95% CI) of current asthma/severe asthma and smoking variables, corrected for sociodemographic and lifestyle variables, were estimated using generalized linear models with Poisson regression, logit link, and robust variance. Results: The prevalence of current asthma and severe asthma were significantly higher in adolescents who were exposed to: experimentation (current asthma: PR = 1.78, 95% CI: 1.51–2.09; severe asthma: PR = 2.01; 95% CI: 1.35–2.98); current smoking (current asthma: PR = 2.08, 95% CI: 1.65–2.64; severe asthma: PR = 2.29; 95% CI: 1.38–3.82); regular smoking (current asthma: PR = 2.25, 95% CI: 1.64–3.07; severe asthma: PR: 2.41; 95% CI: 1.23–4.73); and passive smoking (current asthma: PR = 1.47, 95% CI: 1.27–1.67; severe asthma: PR = 1.66; 95% CI: 1.19–2.32); these associations remained significant after adjustment. Conclusions: Asthma and smoking were significantly associated in Brazilian adolescents, regardless of the sociodemographic and lifestyle factors, notably in those with more severe disease.
