Abstract:
Background: According to statistics from National Center of Public Health Development of Mongolia morbidity rate of cardiovascular diseases was 501.84 cases per 10000 population in 2006, which demonstrates increase of 2 times compare to 1996 and 50% increase compare to 2000. Goal: To study bio-ecological factors influencing on mortality and morbidity rate of prevalent cardiovascular diseases among Mongolians.Materials and Methods: We have chosen arterial hypertension, acute myocardial infarction, and chronic rheumatoid fever according 10th classification of WHO. Indices of morbidity, mortality of diseases were calculated per 1000 population.Result: Average atmospheric temperature t0С (χф2=1494); atmospheric pressure (χф 2=36.07); precipitation (χф 2=704); and mineralization of rivers (χф 2=532) have statistically significant effect on morbidity rate of arterial hypertension among the population of Uvurkhangai, Gobi-Altai, Darkhan-Uul, Gobisumber aimags and UB city. Average atmospheric temperature t0С (χф 2=241); atmospheric pressure (χф2=88.62); precipitation (χф 2=62.18); and mineralization of rivers (χф2=86.28) have statistically significant effect on morbidity rate of chronic rheumatoid fever among the population of Arkhangai, Bayankhongor, Umnugobi, Gobisumber aimags.Conclusions:1. Geographical distribution of arterial hypertension is prevailed in Uvur-Khangai, Gobi-Altai, Darhan-Uul, Gobi-Sumber aimags and UB city, distribution of acute myocardial infarction is prevailed in Hovd, Hubsgul, Arkhangai, Selenge, Gobi-Sumberaimags and geographical distribution of chronic rheumatoid fever is prevailed in Bayankhongor, Arkhangai, Umnugobi, Gobisumber aimags. 2. Ecological factors have statistically significant (χF 2=23.1-161.1) influence on the distribution of morbidity and mortality of arterial hypertension, acute myocardial infarction and chronic rheumatoid fever. Influencing ecological factors in regions covered with this study, such as temperature, atmospheric pressure, wind speed and mineralization of water sources have weaker and reverse correlations each separately (r=-0.1-0.2) but in combination they have medium and reverse correlations (r =-0.45- 0.52).3. The result of the research study established that morbidity and mortality of cardiovascular diseases (arterial hypertension, acute myocardial infarction and chronic rheumatoid fever) distributed in 3 regions on the territory of Mongolia depending on ecological factors.
