Some factors of urban environment impact for population morbidity rate

Abstract

Over the past 20 years, the number of migrants from rural areas to Ulaanbaatar has increased by 7-10 times compared with the pre-1990s, and about 30,000 people migrate annually, which exceeds the economic, social and ecological burdens of Ulaanbaatar. Also increasing the incidence of infectious and non-communicable diseases and water, air and soil pollution. Therefore, the impacts of infectious and non-infectious diseases on population of some of Mongolia's major urban settlements have been studied. As population influx and ger district population increase, the incidence of morbidity among the population increases with the directed relation with pneumonia (Rxy = 0.573, p = 0.007) and ischemic heart diseases (Rxy = 0.976, p = 0.001). Pulmonary pneumonia and heart diseases are with direct relation with medium income (Rxy = 0.965, p = 0.001), fuel price (Rxy = 0.939, p = 0.001) and population density in ger districts (Rxy = 0.794, p = 0.001). The concentration of sulfur dioxide and nitrogen dioxide in the outdoor air is directly influenced to pneumonia (Rxy = 0.896, p = 0.001), ischemic heart diseases (Rxy = 0.902, p = 0.001) and cold air is direct relation with pneumonia (Rxy = 0.475, p = 0.03) and ischemic heart disease (Rxy = 0.543, p = 0.01) respectively. There are three major factors affecting the population morbidity and social factors are with high incidence, which are more than 99.4 percent (6.6-7.9%) and the deviation of the factors that are likely to be statistically significant. Environmental pollution in urban areas, especially air pollution, has a negative impact on the health of the population. Some urban factors, including socio-economic factors such as wages, good price increasing, and increased number of cars are adversely affected.
