“…In this study, there was a positive and strong significant re lationship between NO 2 and cardiovascular deaths in the case of under 18-year-olds after 11-day lags. In this regard, in Dadbakhsh et al's study, in Shiraz, Iran, the results showed that NO and NO X had a direct and significant rela tion with total cardiovascular deaths, and female deaths in the same month and total cardiovascular deaths that hap pened one month later [2]. In the study from China, nitro gen dioxide was also associated with an increase in isch emic heart disease death [41].…”

“…Nowadays, various natural and ar tificial sources have caused changes in the physical and chemical properties of ambient air and have caused "air pollution" [1,2]. Air pollutants have a wide range of im pacts on human health and are considered to be one of the major environmental health issues in megaindustrial world cities [3].…”

“…The results of Dadbakhsh et al in Shiraz, Iran also showed that nitrogen monoxide (NO) and nitrogen ox ides (NO X ) were significantly related to total cardiovas cular deaths; NO, NO X and sulfur dioxide (SO 2 ) were significantly related to female deaths and SO 2 was sig nificantly related to deaths in the case of 18-to 60-yearolds. Nitrogen monoxide and NO X pollutants were also related to all cardiovascular deaths that happened one month later [2]. The most important adverse effects of air pollution in clude the incidence of cardiovascular complications such as heartthrob, fluctuating heart rate, increased blood pres sure, increased vascular tone, blood coagulation, athero sclerosis [16] and increased mortality [17].…”

“…Indus trial development and increase in the number of motor vehicles have increased atmospheric pollutants all over the world, and therefore conducting studies from various parts of the world may help provide a better understand ing of the global problem of air pollution [20]. Several studies have been conducted about the effect of air pollution on cardiovascular deaths with crosssection al, cohort and time series methodologies [2,15,21,22]. However, a study that evaluates the acute effect of air pol lution on cardiovascular deaths has not been conducted in Ahvaz yet; and so far the only available knowledge has been obtained through studies carried out using the Air Q model to estimate the effects of air pollution on respira tory and cardiovascular diseases [22][23][24].…”

Objectives: There are few studies about the association between breathing polluted air and increased risk of cardiovascular diseases and cardiac death in the Middle East. This study has aimed to investigate the relation between air pollutants and cardio vascular mortality (based on the International Statistical Classification of Diseases and Related Health Problems, 10th revision) in Ahvaz. Material and Methods: In this ecological study, the data about cardiovascular disease mortality and air pollutants from March 2008 until March 2015 was inquired from the Ahvaz City Authority and the Khuzestan Province Environmental Protec tion Agency. The quasi-Poisson, second degree polynomial constrained, distributed lag model; using single and cumulative lag structures, adjusted by trend, seasonality, temperature, relative humidity, weekdays and holidays was used for the data analysis purposes. Results: Findings indicated a direct significant relation between an interquartile range (IQR) increase in ozone and cardiovascular deaths among men after 3 days' lag. There was also a significant relation between an IQR increase in particulate matter below 10 μm and cardiovascular deaths for all people, over 60 years old and under 18 years old after 3 and 13 days' lags. There was a significant relation between an IQR increase in nitrogen dioxide and carbon monoxide, and cardiovascular deaths in the case of under 18-year-olds (in the lag 11) and over 60-year-olds (in the lag 9), respectively. We finally found a significant association between an IQR increase in sulfur dioxide and cardiovascular deaths in the case of men, under 18-year-olds and from 18-to 60-year-olds in the lag 9, 0, and 11, respectively (p-values < 0.05). Conclusions: It appears that air pollution is signifi cantly associated with cardiovascular deaths in Ahvaz City. Int J Occup Med Environ Health 2018;31(4)

BackgroundSome epidemiological evidence has shown a relation between ambient air pollution and adverse health outcomes. The aim of this study was to investigate the effect of air pollution on mortality from respiratory diseases in Tehran, Iran.MethodsIn this ecological study, air pollution data was inquired from the Tehran Province Environmental Protection Agency and the Tehran Air Quality Control Company. Meteorological data was collected from the Tehran Meteorology Organization and mortality data from the Tehran Cemetery Mortality Registration. Generalized Additive Models (GAM) was used for data analysis with different lags, up to 15 days. A 10-unit increase in all pollutants except CO (1-unit) was used to compute the Relative Risk of deaths.ResultsDuring 2005 until 2014, 37,967 respiratory deaths occurred in Tehran in which 21,913 (57.7%) were male. The strongest relationship between NO2 and PM10and respiratory death was seen on the same day (lag 0), and was respectively (RR = 1.04, 95% CI: 1.02–1.07) and (RR = 1.03, 95% CI: 1.02–1.04). O3 and PM2.5 had the strongest relationship with respiratory deaths on lag 2 and 1 respectively, and the RR was equal to 1.03, 95% CI: 1.01–1.05 and 1.06, 95% CI: 1.02–1.10 respectively. NO2, O3, PM10 and PM2.5 also showed significant relations with respiratory deaths in the older age groups.ConclusionsThe findings of this study showed that O3, NO2, PM10 and PM2.5 air pollutants were related to respiratory deaths in Tehran. Reducing ambient air pollution can save lives in Tehran.

Death from respiratory diseases and temperature in Shiraz, Iran (2006–2011)

et al. 2016

Some studies have suggested that the number of deaths increases as temperatures drops or rises above human thermal comfort zone. The present study was conducted to evaluate the relation between respiratory-related mortality and temperature in Shiraz, Iran. In this ecological study, data about the number of respiratory-related deaths sorted according to age and gender as well as average, minimum, and maximum ambient air temperatures during 2007-2011 were examined. The relationship between air temperature and respiratory-related deaths was calculated by crude and adjusted negative binomial regression analysis. It was adjusted for humidity, rainfall, wind speed and direction, and air pollutants including CO, NO, PM, SO, O, and THC. Spearman and Pearson correlations were also calculated between air temperature and respiratory-related deaths. The analysis was done using MINITAB16 and STATA 11. During this period, 2598 respiratory-related deaths occurred in Shiraz. The minimum number of respiratory-related deaths among all subjects happened in an average temperature of 25 °C. There was a significant inverse relationship between average temperature- and respiratory-related deaths among all subjects and women. There was also a significant inverse relationship between average temperature and respiratory-related deaths among all subjects, men and women in the next month. The results suggest that cold temperatures can increase the number of respiratory-related deaths and therefore policies to reduce mortality in cold weather, especially in patients with respiratory diseases should be implemented.
