Cambios en la prevalencia de asma en escolares chilenos entre 1994 y 2002: International Study of Asthma and Allergies in Childhood (ISAAC) - Chile phases I and III
“…However, the majority of these studies were performed in Europe and Asia; only three of these were conducted in Latin America, of which one was in Chile 11 and two in Brazil. 16,20 The ISAAC investigates the prevalences of wheezing in the last 12 months and self-reported asthma in life as outcomes of this disease.…”

“…The recent literature on time trends in asthma shows the large use of the comparison between stages I and III of ISAAC, 2,5,11,15,16,20 which observed this prevalence in the six-and-seven-year age group, in the 13-and-14-year age group, or in both. However, the majority of these studies were performed in Europe and Asia; only three of these were conducted in Latin America, of which one was in Chile 11 and two in Brazil.…”

“…Este estudio demuestra que las cifras de prevalencia de asma varían mucho en distintos países 6 . En Chile, 10 a 15% de los niños en edad escolar son asmáticos, se considera un promedio de 12% 5 .…”

“…Se demostraron diferencias significativas (p < 0,001) en todas las variables que componen los criterios del IPA. En nuestros pacientes, la probabilidad de desarrollar asma fue al menos 24 veces mayor si tenían índice IPA positivo (OR 84,3 IC 95% 24, 5). Conclusión: El índice IPA es una buena herramienta para predecir asma, y permite tomar decisiones acertadas en pacientes sibilantes menores de tres años.…”

Association of the asthma predictive index and presence of the disease in children in Valdivia, Chile There are predictive indexes to identify asthmatic patients from the rest of the recurrent wheezing phenotypes. The aim of this work was to evaluate the association between the positive Asthma Predictive Index (API) and the presence of asthma between the age of six and seven years old, in children from Valdivia, Chile. Methods: API was applied to 101 asthmatic children (cases) and 100 non-asthmatic children (controls). Data were analyzed using STATA v.11 (2009). Fisher Exact Test was used to determine the relationship between variables. Results: 72.3% of asthmatic patients and 3% of non-asthmatic patients had a positive index. Significant differences (p < 0.001) were shown in all the variables included in the API. In our group of patients, the probability for a child to develop asthma was at least 24 times higher if he/she had a positive API (OR = 84.3 CI 95% 24.1-436.5). Conclusion: API is a good tool to predict asthma and allows to take right decisions in recurrent wheezing children younger than 36 months old.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
