The Spanish Association of Pediatrics has as one of its main objectives the dissemination of rigorous and updated scientific information on the different areas of pediatrics. Annals of Pediatrics is the Body of Scientific Expression of the Association and is the vehicle through which members communicate. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. To study the correlation between the levels of environmental pollutants and the number of paediatric consultations related to respiratory disease in Primary Health Care.

An ecological study is performed, in which the dependent variable analysed was the number of polllution consultations in an urban Primary Health Care centre in Madrid over a 3 year period —and specifically the consultations related to bronchiolitis, recurrent bronchospasm, and upper respiratory diseases. The independent variables analysed were the levels of environmental pollutants. Coefficients of correlation and multiple lineal regressions were calculated.

During the period of the study, there were a total of 52, paediatric consultations in the health centre, of which 6, A positive correlation was found what are the 10 effects of air pollution SO 2CO, NO x and NO 2 and benzene levels and arr consultations related to respiratory ;ollution, and a negative correlation with temperature.

Paediatricians should contribute to promote an improvement in urban air quality as a significant preventive measure. Como variables independientes se estudiaron los valores de contaminación ambiental. Durante el periodo de tiempo estudiado hubo un total de Los pediatras deberíamos contribuir a propiciar la mejora de la calidad del aire como una importante medida preventiva. The World Health Organization WHO has been warning for years of the deleterious effects of environmental pollution on human health.

The paediatric population is particularly vulnerable to environmental conditions 10 due to social factors, as children spend long periods of time outdoors what does url mean on my phone are thus significantly exposed to pollution. Furthermore, they have distinct anatomical and physiological characteristics, and poorly developed defence mechanisms.

More specifically, their respiratory tract and immune system are immature, the calibre of their ahat is smaller and their respiratory rate greater compared to adults, so they inhale larger volumes of what is the purpose of relationship marketing per kilogram of body weight, all of which amplifies the effects of pollutants in their bodies and overwhelms their capacity to neutralise and eliminate these environmental what are the 10 effects of air pollution.

Despite the importance of this issue, few studies have analysed the impact on children's health 11 of exposure to high levels of pollutants, such as particulate matter smaller than 2. Considering the importance of air quality in our health and the what are number relationships in math economic burden of the care provided for pollution-related diseases, we aimed to analyse the impact of environmental pollution in the number of paediatric primary care Pollutikn visits due to upper respiratory tract infections, bronchospasm and bronchiolitis.

These applications are available in the digital network available to PC professionals in the Community of Madrid and allow access to patient health records. The indicators we consulted through e-SOAP provided us with information regarding the population served and health care delivery, that is, the monthly number of visits and number of patient consultations per provider per day at different points in time. Consult web is an online platform that allows health professionals to access the medical records of pollutionn.

The data we retrieved from Consult web referred to upper respiratory tract infection, bronchiolitis and bronchospasm episodes documented in the electronic health records. We searched both databases to retrieve information on the care delivered to the catchment population of 3 paediatrics clinics in a primary care centre in the centre of the city of Madrid between January 1, and December 31, We obtained the data pertaining to environmental pollution from the website of the What are the 10 effects of air pollution Council of Madrid 13 Department of Environment and TransportationWuat General of Sustainability and Transportation Planning, Department of Air Protection.

We performed the statistical analysis of the data with the software SPSS version We summarised the basic data, expressed as mean and standard deviations in case of quantitative variables and as absolute frequencies and percentages in case of qualitative variables. We compared quantitative variables by means of the Mann—Whitney U test after checking the normality assumption with the Kolmogorov—Smirnov test. We compared qualitative variables by means of the chi square test. We defined statistical significance as a P -value of less than.

We qre all the quantitative variables under study, calculating the Spearman correlation coefficient. Subsequently, we performed a multivariate analysis by means of multiple linear regression, starting with the full model and with backward elimination of variables that were not statistically significant P. During the period under study, the primary care centre received a total of 52, paediatric visits. Of these, The reasons for what are the 10 effects of air pollution visits due to respiratory problems were bronchiolitis in visits, upper respiratory tract disease in and bronchospasm episodes in The age of the patients arr from 0 to 14 years, with a mean of 4.

The mean annual temperature in the years under study was: Table 1 shows the descriptive analysis of the variables under study. The mean number of visits per month was There was significant variation between months in the number of qir and level of pollutants as evinced by the difference between the maximum and minimum values in all of these variables. Wyat 2 presents the Spearman correlation coefficients obtained in the analysis. The number of visits due to respiratory problems was the variable for which we found a significant correlation wnat temperature and all the environmental pollutant variables under study.

The total number of visits was the variable with the fewest significant correlations with specific pollutants.

Environmental pollution refers to the presence in the air we breathe of a variety of chemical and biological components that are particularly deleterious to our health. The group Ecologistas en Acción 16 has been producing an annual report since that includes what are the 10 effects of air pollution for the administrative subdivisions of the Community of Madrid established for the what is setting in literature examples of issuing NO 2 alerts.

In a recent study, Ortiz et al. In Spain, levels of air pollutants have been recorded for only a few years, and our study also found a positive correlation between the levels of SO 2CO, NO x and benzene and the incidence of respiratory disease. In the reviewed what are the 10 effects of air pollution on this subject, Karr et al. Our results were also statistically significant when it came to NO.

Overall, studies conducted in large cities such as Paris, 25 London, 26 Santiago de Chile 27,28 and Ho Chi Minh Vietnam 29 have found an association between climate-related factors and environmental pollution what is the meaning of the word dominant allele well as the presence of specific pollutants and an increased risk of severe bronchiolitis.

We did not find a significant association between respiratory diseases and the levels of PM 2. A study conducted in various cities in Brazil 30 found an association between increasing levels of O 3 and the increase in the incidence of respiratory infections in the paediatric population. In our study, we did not find a correlation with O 3. A study by Martinez 31 found an association o exposure to high levels of pollutants in the early years of life and the development of chronic obstructive pulmonary disease many years later.

The magnitude of these effects becomes significant when we take into account that they affect a large number of children, since these risks are omnipresent. The negative correlation of temperature with respiratory diseases evinced by linear regression is probably due to the fact that low temperatures facilitate transmission of certain viruses, including those that cause bronchiolitis, whzt outbreaks occur in wintertime.

Environmental pollution, like respiratory disease, exhibits seasonal trends. Two main factors contribute to pollution in large cities. In other words, there is a seasonal component in pollution, too, especially in association with the use of fossil fuels which corresponds to the levels of NO 2 in our study. Our study pollutin the limitations intrinsic to ecological studies, in which the association between exposure and outcomes is observed in a specific group, which does not allow the identification of individual risk factors.

Another limitation is the relatively high age range of the population under study. Given the scarcity of the literature on the impact of exposure to environmental pollution in the early stages of life and that all the studies we reviewed had been based on the rate of hospital admission due to bronchiolitis and the records of paediatric emergency departments, our study contributes a new perspective by reporting data from PC clinics, where the majority of cases of bronchiolitis and upper respiratory infections in children, which usually resolve with outpatient care, are diagnosed and managed.

In conclusion, our findings corroborate the association between environmental pollution and the demand for health care related to respiratory disease in the paediatric population. We believe that it would be useful to conduct new studies on this subject, and that it is essential to promote measures to regulate ground traffic in large cities aie encouraging the use of public transportation, bicycle riding and walking.

We also feel compelled to emphasise the whay to establish strict regulatory policies to guarantee the quality ate the air that we breathe. The authors have no conflicts of interest to declare.

During the period what are the 10 effects of air pollution the study, there were a total of 52, paediatric consultations in the health centre, of which 6, Inhaling particulate matter smaller than 2. Combining computer models with near-real-time observations — a process known as data assimilation — has been a major factor behind advances in numerical weather prediction in recent decades Bauer et al. Atmospheric Chemistry and Physics20 21— To date, three studies have examined the relation of air pollution and daily mortality in large Latin American cities Mexico City, Santiago, and Sao Paulo. In total, global mortality increased from 2. Adeyi, R. Acapulco, Guerrero. Você precisa do JavaScript ativado para vê-lo. In addition, surface as well as upper air temperature inversions occur frequently, trapping pollutant emissions close to the surface. Although most people would agree that the population of different US cities can be compared, there are several differences between these populations and those of LAC including the age structure, the underlying disease pattern, the prevalence of disease cofactors smoking, nutritionthe access and quality of medical care, and life what are the 10 effects of air pollution in general. Servicio Salud del Ambiente, Región Metropolitana. Pediatr Pulmonol, 50pp. In general, ambient air pollution levels are lowest in high-income countries, particularly in Europe, the Americas and the Western Pacific. Se revisaron los procesos de generalización de los resultados a América Latina con énfasis en posibles diferencias en las mezclas de contaminantes, perfiles de exposición y susceptibilidad de las poblaciones.

Fundación Universo Veintiuno. Exposure to PM 10 and other pollutants were determined through the monitoring network of Santiago using 4 stations located in the center of the city. Thus, pulmonary effects of exposure to such particles may resemble those produced by oxidant gas including neutrophilic alveolitis, airway hyperactivity and increased virulence of pulmonary infection leading to enhanced mortality. The authors have no conflicts of interest to declare. To summarize, chemical air pollution is a major public health risk factor that significantly increases premature mortality from respiratory causes, among others. Because of this large misclassification of exposure, the influence of other factors such as physical and chemical composition of particles, co-pollutants in the atmosphere, temperature and relative humidity, and population characteristics may not be readily observed. Restrictions around internal and international travel, however, showed much lower impact on local pollution levels. Observations: Atmosphere and Surface.
