The geographical analysis of lung cancer deaths in the metropolis of Tehran with an epidemiological approach during the period 1397-1387

Lung cancer is one of the most common causes of cancer death worldwide. In this study, the metropolis of Tehran has been selected as the most populous and polluted city in the country for research on lung cancer. 4158 deaths from lung cancer occurred during the study period in Tehran and Attempts have been made to use descriptive and inferential methods, as well as GIS software, to analyze the epidemiology of lung cancer and the factors that affect it (important risk factors). Based on this, the coefficient of changes and drawing of diagrams and maps have been used to study the current trend and the growth model has been used for forecasting. Important variables such as old age, smoking, asbestos and gender emissions, and habitat were also examined. The findings show that areas in central and southern Tehran have more deaths from lung cancer than other areas, and areas in the west (21 and 22) have experienced lower rates. Mortality rates are higher for men than for women of all ages, and 61.04% of lung cancer deaths are in the age group of 65. The results of the change coefficient model showed that the death rate due to this disease has been increasing during the years 1390 to 1394 and in 1396 there has been an increasing trend. Also, some areas of Tehran in terms of age (3 and 6) and smoking (3, 7 and 15) as well as asbestos emissions (increase in 1397) are more likely to suffer from death from lung cancer. Finally, according to the growth model, the northern and eastern regions and some central regions will continue to face the current trend of more deaths from lung cancer. As a result, it seems that to prevent and effectively control deaths from respiratory diseases, individual policies and health care measures should be integrated with urban planning strategies, including controlling environmental pollutants and implementing environmental health programs.
