This article is from BMC Pulmonary Medicine, volume 14.AbstractBackground: Asthma and allergies are world-wide common chronic diseases among children and young people. Little information is available about the prevalence of these diseases in rural areas of Latin America. This study assesses the prevalence of symptoms of asthma and allergies among children in urban and rural areas at Oropeza Province in Bolivia. Methods: The Spanish version of the ISAAC standardized questionnaire and the ISAAC video questionnaire were implemented to 2584 children attending the fifth elementary grade in 36 schools in Oropeza province response 91%. Lifetime, 12 months and severity prevalence were determined for asthma, rhinitis and eczema symptoms. Odds ratios OR with 95% confidence intervals 95% CI were calculated adjusting for age using generalized linear mixed-effects models. Results: Median age of children was 11 years, 74.8% attended public schools, and 52.1% were female. While children attending urban schools had lower prevalence of self-reported wheeze in the written questionnaire adjusted OR 0.6; 95% CI 0.4-1.9, they were more likely than children attending rural schools to report wheeze in the video questionnaire aOR 2.1; 95% CI 1.0-2.6. They also reported more frequently severe rhinoconjunctivitis aOR 2.8; 95% CI 1.2-6.6 and severe eczema symptoms aOR 3.3; 95% CI 1.0-11.0. Conclusion: Overall in accordance with the hygiene hypothesis, children living in urban areas of Bolivia seem to have a higher prevalence of symptoms of asthma and allergies compared to children living in the country side. In order to develop primary prevention strategies, environmental factors need to be identified in future studies.
