“…Between 1998 and 2000, an epidemiological study was carried out in six Colombian cities (Barranquilla, Bogotá, Bucaramanga, Cali, Cartagena and Medellín) where symptoms associated with asthma, rhinitis and atopic dermatitis were found to show prevalences of 10.4%, 22.6% and 3.9%, respectively, in the registered population. Allergic rhinitis displayed a cumulative prevalence of 31.1%, with Medellin being the most affected city among those included in the study (Dennis et al 2004). At the same study, it was established that allergic rhinitis exhibited a cumulative prevalence of 31.3%, with the group showing the greatest problems among individuals aged 12 to 18 years, and the city of Medellin again appeared to be the most affected city among those included in the study.…”

“…The percentage of people who are allergic to pollen grains and fungal spores can reach high levels in densely populated areas such as Medellin, bolstered by the presence of toxic atmospheric contaminants in such cities. The high prevalence of allergenic pathologies reported in the city of Medellin (Dennis et al 2004) is most likely correlated with the types of pollen and spores present in the atmosphere in this region.…”

-(Atmospheric pollen and spore content in the urban area of the city of Medellin, Colombia). The atmosphere of the urban area of the city of Medellin, Colombia was monitored with the objective of identifying airborne pollen and spores throughout a whole year. Sampling was performed between February 2010 and March 2011, coinciding with the La Niña climate phenomenon, which is characterized by a considerable increase in precipitation. Samples of airborne spores and pollen were obtained from a suction Hirst-type volumetric sampler. A total of 62 pollen and spores types were recorded during sampling, of which 30 were angiosperms, two were gymnosperms, 10 were monilophytes, and 20 were fungi. The families displaying the highest pollen counts were Oleaceae, Poaceae, Cyperaceae, Chenopodiaceae and Polypodiaceae. We recorded an inverse relationship among precipitation and the quantity and diversity of pollen grains and fern spores. The angiosperm and gymnosperm taxa showed the greatest recorded grains throughout the sampling year with respect to the species mentioned herewith, which have been reported as allergenic in various aerobiological studies.

Se realizó un monitoreo de la atmosfera del área urbana de Medellín, con el objetivo de identificar polen y esporas que se transportan por el aire a lo largo del año. El muestreo se realizó entre febrero de 2010 y marzo de 2011. Las muestras de polen y esporas aéreas se obtuvieron utilizando un captador volumétrico de succión tipo Hirst. En el trabajo se registraron 62 tipos polínicos y esporas, de las cuales 30 corresponden a angiospermas, dos a gimnospermas, 10 a pteridofitos y 20 a hongos. Las familias con mayor número de individuos por muestreo fueron: Oleaceae, Poaceae, Cyperaceae, Chenopodiaceae y Polypodiaceae. Se observó una relación inversamente proporcional entre la cantidad y diversidad de granos de polen y esporas de helechos encontrados, con respecto a la precipitación a lo largo del muestreo. Los taxones de angiospermas y gimnospermas que mayor cantidad de granos aportaron en los conteos durante el año de muestreo, corresponden a especies introducidas, con reportes de alergenicidad.

“…However, the prevalence of rhinitis and asthma in rural communities or low-income countries is generally lower than in developed westernized urban communities. A considerable difference between the prevalence of symptoms and the prevalence of medical diagnosis detected in underserved populations may suggest a significant proportion of underdiagnosis, which might be related to a lack of awareness and limited access to health care (903,1905). In other developing countries like Vietnam (1906), Nigeria (921), Bangladesh (1907) or Brazil (1908), childhood atopy symptom prevalence and links between rhinitis and asthma are similar to those in developed countries.…”

“…La prevalencia acumulada de signos y síntomas indicativos de asma (haber presentado alguna vez en la vida ruidos en el pecho al respirar) fue de 25,6% y la de asma diagnosticada por médico fue de 8,4%, similares a las encontradas por Dennis et al (15) que fueron de 28,1% y 8,4%, respectivamente, en el grupo de 5 a 11 años. Se han encontrado resultados de prevalencia similares, también, en escolares de ciudades de Perú (16).…”

Prevalencia de síntomas respiratorios indicativos de asma y asociación con contaminación atmosférica en preescolares de Bucaramanga, Colombia

Introducción. Actualmente se sabe que el incremento de los niveles de contaminación atmosférica externa e interna se asocia con efectos nocivos para la salud, especialmente asma y otras alergias. Objetivos. Determinar la prevalencia de síntomas respiratorios indicativos de asma en la población preescolar y compararla entre zonas con diferentes niveles de contaminación atmosférica en Bucaramanga, Colombia. Materiales y métodos. Estudio observacional analítico de corte transversal que compara los síntomas respiratorios en menores de siete años de dos zonas de la ciudad con niveles diferentes de contaminación por material sólido en partículas y ozono. La morbilidad fue medida con un cuestionario sobre síntomas respiratorios indicativos de asma, validado al español.Resultados. Se estudiaron 768 niños distribuidos de las zonas de alta y baja contaminación. El uso de cigarrillos (27,5%) y aerosoles (22,7%) se encontraron como las fuentes de contaminación más frecuentes dentro de las viviendas. La prevalencia de ruidos respiratorios a lo largo de la vida fue de 25,6% (IC95% 23,2-29,8) y la de diagnóstico médico de asma fue de 8,4% (IC95% 6,2-11,5), sin diferencias significativas entre las zonas. El modelo final no mostró asociación entre la contaminación atmosférica y la presencia de síntomas respiratorios indicativos de asma. Por el contrario, la presencia de pisos de cemento y moho mostró una asociación significativa con estos síntomas. Conclusiones. Es posible que en Bucaramanga los factores de contaminación domiciliaria puedan tener un mayor efecto sobre la presencia de síntomas respiratorios indicativos de asma en menores de siete años que los contaminantes externos.Palabras clave: signos y síntomas respiratorios, asma/epidemiología, contaminación del aire, preescolar. Respiratory symptoms associated with asthma prevalence and air pollution in preschool childrenIntroduction. Increases in the air pollution levels has well-documented harmful effects on human health, especially exacerbating problems of asthma and other allergies. Objective. The prevalence of symptoms associated with asthma was determined in preschool populations in zones with differing levels of air pollution. Materials and methods. A cross-sectional study was conducted in Bucaramanga, Colombia, comparing respiratory symptoms in 768 children under seven years in two urban zones with different pollution levels of particulate matter and ozone. Morbidity was evaluated for respiratory indicators of asthma by means of a questionnaire version previously validated in Spanish. Results. The use of cigarettes (27.5%) and aerosols (22.7%) were the most frequent source of indoor air pollution. Wheezing prevalence was 25.6% (95% CI 23.2-29.8%) and diagnosis of asthma was 8.4% (95% CI 6.2-11.5%), with no differences between zones. The final multivariate model did not show an association between outdoor pollution and symptoms related with asthma. However, concrete flooring and presence of mold did show an association with these symptoms. Conclusions. Indoor air qua...
