ABSTRACT
BackgroundHuman-induced climate change will affect the lives of most populations in the next decade and beyond. The impact of meteorological conditions on human health has been reported globally. There is a need to conduct surveys for correlation between climate change and human health.GoalTo study the impact of air temperature on human health in selected aimags and city districts.Materials and MethodsIn order to study how climate change and air quality parameters affect human health we selected Zavhan, Selenge, Dornod, and Umnugobi aimags which represent different climate zones and 2 districts of Ulaanbaatar city during 2009-2011. All data for respiratory system disease J00-J99, circulatory system disease I00-I99, were collected from soum, district’s hospital, and aimag and soum’s Department of health.ResultsDuring the study period, a total number of 8649 incidences of respiratory disease are registered. From them 74.2 percent are influenza and pneumonia (J09-J18), 17.6 percent are other acute lower respiratory infections (J20- J22), and 8.2 percent are asthma (J45-J45.9). For cardiovascular disease 15288 incidences are registered. From them 65.6 percent are hypertensive disease (I10-I15), 23.6 percent are ischemic heart disease, and 10.8 percent are cerebrovascular diseases (I60-I69). The lower the air temperature, higher the incidence of influenza and pneumonia, acute lower respiratory infections, hypertensive, and ischemic heart disease.ConclusionsCold weather is correlated with a higher incidence of respiratory and cardiovascular diseases.
