Prevalence of asthma symptoms in Latin America: The international study of asthma and allergies in childhood (ISAAC)

Associations of place of birth with asthma and wheezing in Mexican American children

“…8,9 In addition, the findings of this study are consistent with those from previous investigations [4][5][6][7]12,13 showing that the prevalence of asthma and wheezing increased in immigrants who moved from areas of relatively low to relatively high prevalence of asthma or asthma-related symptoms. It could be argued that the observed difference in the prevalence of doctor-diagnosed asthma between USborn and Mexico-born children is a result of variations in diagnostic practices or access to health care.…”

“…Studies on asthma in Mexico that used a methodology similar to that of studies conducted elsewhere in the world 8,9 noted a low prevalence of asthma and asthma symptoms in Mexican school children. In the United States, Mexican Americans had a lower prevalence of asthma and asthma symptoms than other ethnic groups.…”

Increased asthma and respiratory symptoms in children exposed to petrochemical pollution

“…Health and demographic information was obtained from parents by using a questionnaire modified from the International Study on Asthma and Allergies in Children, 21 which was translated into Spanish and validated in a pilot study. 22 Additional data collected included children's medical histories, asthma severity and known triggers, allergic status, medical management, family structure and demographics, and potential indoor exposures.…”

“…Asthma was defined as ''doctor-diagnosed asthma'' and according to the International Study on Asthma and Allergies in Children definition. 21 Lung function testing. A randomly selected group of 181 children had lung function measured by means of standard spirometry.…”

Advances in adult asthma diagnosis and treatment and health outcomes, education, delivery, and quality in 2011: What goes around comes around

“…The International Study on Asthma and Allergies in Childhood found Peru to have the highest prevalence of childhood asthma symptoms among the countries of Latin America. 44 Olmedo et al 45 analyzed exposure and sensitization to indoor allergens as part of the New York City Neighborhood Asthma and Allergy Study, a case-control study among children from middle-income families living in high-asthma-prevalence neighborhoods (HAPNs) versus low-asthma-prevalence neighborhoods (LAPNs). HAPN homes had higher concentrations of cockroach, mouse, and cat antigen but lower concentrations of mite than LAPN homes.…”
