Background. Prevalence of essential arterial hypertension is 60-80% among cardiovascular diseases and WHO reported that prevalence of essential arterial hypertension was 90-95% of arterial hypertension and 80% of hospitalized arterial hypertension patients. One of risk factors of essential arterial hypertension is (lack) deficiency of physical activity. Therefore we studied a benefit of exercise in essential arterial hypertension therapy. Methods. We examined blood lipid level and some of cardiovascular indicators of essential arterial hypertension patients such as arterial pressure, heart rate before and after treatment of exercise. Results. Prevalence of essential arterial hypertension was higher in the patients with obesity and overweight. Right high and low blood pressures were decreased from 154 to 141 and from 93 to 85, respectively. The other hand left high and low blood pressures were decreased from 154 to 138 and from 94 to 86, respectively. Heart rate was decreased from 76 to 71.9. Conclusions. Arterial pressure, heart rate and lipid level of the patients with essential arterial hypertension were significantly decreased after treated by exercise.

IntroductionThe degree to which the change of season influences mood, energy, sleep, appetite, food preference,and the wish to socialize has been called “seasonality” [1]. In 1984 Rosenthal and associatesdescribed the syndrome of “seasonal affective disorder” (SAD), a condition where depressions in falland winter alternate with non-depressed periods in the spring and summer [5]. Seasonal AffectiveDisorder (SAD) is supposed to be caused by lack of daylight in winter [6]. Ulaanbaatar city is thecoldest capital in compared with medium temperature of the world. That’s why, it is an idea that wesupposed to there might be a seasonal affective disorder in this city. There is nothing to be studiedbefore related to this topic and that is our goal of the study.GoalTo determine a seasonal affective disorder in the adults of Ulaanbaatar cityMaterials and MethodsIn this study, we examined 560 healthy people between 20-60 aged livings in the Ulaanbaatar cityusing by Seasonal Pattern Assessment Questionnaire.ResultGender distribution showed an increased incidence of females (56.1%, 314 cases) compared withmale (43.9%, 246 cases). Distribution by age groups shows that 20-29 years were 237 (42.3%),30-39 years were 99 (17.6%), 40-49 years were 132 (23.5%), and 50-59 years were 92 (16.4%).According to the Seasonal Pattern Assessment Questionnaire, below 8 score was 323 (57.6%), 9-10 score 53 (9.4%), over the 11 score 184 (33%).ConclusionAccording to the questionnaire of Seasonal pattern assessment, 33 percent were seasonal affectivedisorder. It means Mongolian people of Ulaanbaatar have Seasonal affective disorder.
