Objective: To determine the prevalence and risk factors associated with tobacco use during the period of confinement in light of the COVID-19 pandemic., Methods: Through an analytical and cross-sectional study, the data of 2, 372 participants were analyzed. The information was collected through a self-administered questionnaire that was built with the Google Forms tool, which was distributed and applied via email and WhatsApp; the private messaging platform. The relationship between the independent variables and the outcome was determined by multivariate logistic regression analysis., Results: Out of the total population, 69.3 % were women, the median age was 20.11±2.01 years, the prevalence of asthma was 12.2 %, and the active tobacco use was 13.3 %. There was a higher number of patients with asthma who smoked (14.2 vs. 13.2 %) than of those who didn't have asthma. The multivariate logistic regression analysis showed that factors like considering that COVID-19 does not exist and not being confined were related to tobacco use in patients with asthma during the implementation of the contingency plan that the COVID-19 pandemic represents., Conclusions: During confinement to home for COVID-19, the prevalence of tobacco use is higher in patients with asthma than in individuals without this ailment; the factors that favor the aforementioned are present in the family environment.

Background: The association between asthma and pregnancy has been documented previously. The relationship between unplanned pregnancy and onset asthma in adolescence has not been studied., Objective: To determine the association between unplanned pregnancy and adolescence onset asthma., Material and Methods: A cross-sectional study was done gathering information about asthma, unplanned pregnancy, family atopy and active or passive smoking in 3,130 adolescents aged 13-19 years. Asthma diagnosis was established through a selfquestionnaire based on the International Study of Asthma and Allergy in Childhood. Odds ratios for asthma were determined using logistic regression model and chi-squared test., Results: Mean age of the participants was 16.37 ± 1.93 years. The prevalence of active smoking was 16.1%, of passive smoking 40% and of family atopy 9.8%. From the pregnant adolescents (785), 59.5% reported had planned not to have a child before pregnancy. Prevalence of wheezing during the year prior to the study was 9.3% and of wheezing during the pregnancy 2%. The prevalence of adolescence onset asthma was 5.4%. The age of initiation of asthma in the adolescence was 14.75 ± 1.60 years. The analysis showed that unplanned pregnancy has a slight risk for the development of asthma during adolescence. (Crude OR=1.03; CI 95% 1.02-1.05; p=0.000)., Conclusion: Unplanned pregnancy, family atopy, active smoking and smoking friends are associated with the onset-asthma in the adolescence.
