“…Gouveia and Fletcher (2000) identified a 1% higher risk of infant pneumonia (RR 1.009[1.001, 1.017]) and a similar risk among the under-five age group as a whole (RR 1.005 [0.998, 1.012]). Hernandez-Cadena et al (2007) also reported an increased risk of similar magnitude in Mexican children and infants below age 6 associated with PM 10 exposure (RR 1.007 [0.987, 1.027]).…”

“…Three of the studies were conducted in Brazil (Braga et al 2001; Conceicao et al 2001; Gouveia and Fletcher 2000; Saldiva et al 1994), and the other two studies were carried out in Mexico (Hernandez-Cadena et al 2007) and Chile (Ostro et al 1999). Six of these time series studies identified a relationship between ALRI morbidity or mortality and increases in PM 10 exposure, with relative risk estimates ranging from 1.00 and 1.09 for every 10-μg/m 3 increase in PM 10 exposure.…”

“…Studies that have found the strongest PM effects generally focus specifically on bronchiolitis (Karr et al 2006; Segala et al 2008), while most of the studies which have used a more broadly grouped disease classification have found similarly inconclusive results for PM 10 (Barnett et al 2005; Gouveia and Fletcher 2000; Hernandez-Cadena et al 2007). …”

Acute lower respiratory infections (ALRI) account for nearly one fifth of mortality in young children worldwide and have been associated with exposures to indoor and outdoor sources of combustion-derived air pollution. A systematic review was conducted to identify relevant articles on air pollution and ALRI in children. Using a Bayesian approach to meta-analysis, a summary estimate of 1.12 (1.03, 1.30) increased risk in ALRI occurrence per 10 μg/m3 increase in annual average PM2.5 concentration was derived from the longer-term (subchronic and chronic) effects studies. This analysis strengthens the evidence for a causal relationship between exposure to PM2.5 and the occurrence of ALRI and provides a basis for estimating the global attributable burden of mortality due to ALRI that is not influenced by the wide variation in regional case fatality rates. Most studies, however, have been conducted in settings with relatively low levels of PM2.5. Extrapolating their results to other, more polluted, regions will require a model that is informed by evidence from studies of the effects on ALRI of exposure to PM2.5 from other combustion sources, such as secondhand smoke and household solid fuel use.

“…This pollutant also presented a greater statistical significance in the research conducted by Nascimento et al, also in children in Sao Jose dos Campos, in relation to hospitalization for pneumonia 10 . On the other hand, in a study conducted in Mexico, there was no significant relationship between ambient levels of PM 10 and emergency visits for respiratory causes 21 .…”

Objective: to estimate the association between exposure to air pollutants and hospital admissions for asthma. Methods: this is an ecological study of time series, which included individuals from 0 to10 years living in Sao Jose dos Campos, for the period 2004 to 2005.Data of hospitalizations for asthma were obtained from DATASUS. The data of ambient levels of particulate matter, sulfur dioxideand ozone were obtained from the Company of Technology of Environmental Sanitation (CETESB) and temperature and humidity from the Foundation for Science, Technology and Space Applications(FUNCATE). Lag models have been made from 0 to 7 days and analyzed by binary logistic regression,yielding odds ratios and their confidence intervals of 95% by SPSS 15.0. Results: there were 809admissions, ranging from 0 to 7. It was possible to identify an association of the particulate matterboth on the same day of exposure and the next third, fifth and sixth days with the admissions; sulfurdioxide was associated with hospitalizations in the first, second and third days after exposure andozone on the third day after exposure to gas. Thus, this study showed an association between airpollutants and asthma hospitalization in a medium-sized city.

“…There are several epidemiological studies realized at a number of cities in Mexico's northern border, where the relationship between changes in human health and the concentration of air pollutants was analyzed, which only few considered; aerobiological pollutants and the increased incidence of childhood asthma in the specified form were found [16,17]. It may be said that there are virtually no studies that specifically analyzed the air pollutants such as fungal spores and the incidence of childhood asthma, despite the high concentrations of air pollutants of this type, reported in taxonomic studies carried out in different parts of Mexico, [18][19][20].…”

Air pollution has affected human life progressively since its sources of origination. It is present in all cities around the world. It has caused harm to humans and other living organisms. This situation has led studies to determine the impact of concentrations of air pollutants in the respiratory ailments. Mexico has developed similar investigations, but unlike other countries' advanced studies on pollutants aerobiology, Mexico's studies have not been conducted in depth, and there is virtually no research work that identifies the air pollutants of fungal spores and their association with respiratory disorders in children. The purpose of this article is to analyze the relationship between air pollution by fungal spores, and the incidence of childhood asthma in Mexicali, Baja California, Mexico. Diagnostics of asthma on children living in the city of Mexicali that received medical care were studied. The records of weather and climatic variables were provided by the Department of Meteorology at the Engineering Institute of UABC. The data of air pollution caused by fungal spores were obtained in three monitoring stations with collectors' rotation and impact of sampling. Mainly four groups of different spores (Alternaria sp., Cladosporiun sp., Bipolaris and Stemphylium) were registered in the atmosphere of Mexicali, with an average of 515 spores/m 3 and a standard deviation of 248 spores/m 3 . The average annual relative humidity was 42.3%. The average temperature showed two different facets; a hot season with temperatures between 22ºC and 44ºC, and a cold season with temperatures between 8.9ºC and 22ºC. The incidence of childhood asthma presented a rate twice the national average (505 cases/one hundred thousand children). The multiple linear regression model proposed showed a significant relationship with a R2=0.86 (p=0.5), which established a direct association between air pollution by fungal spores, and the incidence of childhood asthma.

Infant morbidity caused by respiratory diseases and its relation with the air pollution in Juarez City, Chihuahua, Mexico

Abstract: The wide range of risk is quite important and might represent a substantial cost for the health system as well as for the society. Our results emphasize the need to implement preventive and control measures for air pollution and avoid the worsening of the present situation.
