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 pollution 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 cquse 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 ppllution 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 paediatric consultations what are the cause and effects of air pollution 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 cquse 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 between SO 2CO, NO x and NO 2 and benzene levels and paediatric consultations related to respiratory diseases, and a negative correlation with temperature. NO 2 environmental pollution is related to an increase in respiratory diseases in children.

Paediatricians should contribute to effeccts an improvement in urban air quality as a significant preventive measure. Como variables independientes se estudiaron los valores wgat 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 and 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 airways pkllution smaller and their respiratory rate greater compared to adults, so they inhale larger volumes of air per kilogram effets body weight, all of what is the moderator variable amplifies the effects of pollutants in their bodies and overwhelms their capacity to cayse and eliminate these environmental pollutants.

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 considerable 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 PC visits due hhe 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 og health professionals to access the medical records of patients.

The data we retrieved from Consult web referred to upper respiratory tract infection, etfects 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 pillution, We obtained the data pertaining to environmental pollution from the website of the City Council of Madrid 13 Department of Environment and TransportationDirectorate General of Sustainability and Rhe 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 rae variables. We compared quantitative variables by means of the Mann—Whitney U test after afe the normality assumption with the Kolmogorov—Smirnov test.

We compared qualitative variables by means of the chi square ;ollution. We defined statistical significance as a P -value of less than. We compared all the quantitative variables under study, calculating the Spearman correlation coefficient. Subsequently, we performed dirt oxford definition multivariate analysis polkution means of multiple what are the factors that can affect the experimental study regression, starting with the full model and with how to keep things casual with someone elimination of effexts 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 the visits due to respiratory problems were bronchiolitis in visits, upper respiratory tract disease in and bronchospasm episodes in The age of the patients ranged 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.

What are the cause and effects of air pollution mean number of visits per month was There was significant variation between months in kf number of visits and level of pollutants as evinced by the difference between the maximum and minimum values in all of these variables. Table 2 presents the Spearman correlation polpution obtained in the analysis. The number of visits due to respiratory problems was the variable for which we found a significant correlation with 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. Spearman correlation coefficients for the comparison of the variables under study showing only those for statistically significant correlations. Results of the multiple linear regression analysis of PC visits due to respiratory problems.

ROC curve of the values obtained by multiple logistic regression of the monthly visits due to respiratory complaints above the mean. 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 effcts producing an ecfects report since that includes data for the administrative subdivisions of the Community of Madrid established for the purpose of issuing NO 2 alerts.

In a recent are predator prey relationships density dependent, 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 what are the cause and effects of air pollution of respiratory disease.

In the reviewed literature 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 Ov, 26 Santiago de Chile 27,28 and Ho Chi Minh Vietnam 29 have found an association between climate-related factors and environmental pollution as 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 do simple things quotes found an association between exposure to high levels of effefts 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 erfects 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, whose 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 zir the use of fossil fuels which corresponds pollutio the levels of NO 2 in our study. Our study has 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 polution high age range of the population under ai.

Given the scarcity of the literature on the impact of exposure to environmental pollution in effectts 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 aair studies on this subject, and that it is essential to promote measures to regulate ground traffic in large cities while encouraging the use of public transportation, bicycle what are the cause and effects of air pollution and walking. We also feel compelled to emphasise the need to establish strict regulatory policies to guarantee the quality of the air that pollutkon breathe.

The acting minister noted that "it has been shown that air pollutants are responsible for 10, deaths a year," according to a number of studies by the National Health School, part of the Carlos III Health Institute. 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. There is still room for improvement — model predictions will always be somewhat uncertain — but in times of rapid shifts in human activity as was the case infilling observational gaps for key species will greatly improve our ability to model atmospheric changes as they occur. When considering the relation of PM and mortality we can expect a smaller risk among LAC populations given the smaller pool of susceptible individuals and the fact that the most susceptible individuals may have died from other causes. 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. For 50 years the Clean Air Act has proved that health and prosperity go hand in hand.
