ABSTRACT
Background@#Headache disorders are most prevalent public-health problem. Worldwide, among the adults 46% suffer from primary headache, where the migraine presents 11% and tension type headache (TTH) presents 25%. Recently, one type of the primary headache, medication overuse headache tends to increase. Nowadays, there is no sufficient study about primary headache in Mongolia. So that, it is necessary to investigate prevalence, clinical type and risk factors of the primary headache.@*Purpose@#To study prevalence and risk factors of primary headache in Mongolia.@*Materials and Methods@#This cross-sectional study was carried out from June to November of 2017. Participants aged 18-65 years old were randomly selected from four provinces and three districts of Ulaanbaatar city. The diagnosis of headache was made using the International Classification of Headache Disorders-3 beta. Statistical analysis was performed on SPSS-23 program.@*Results@#A total of 2043 participants (812 men and 1231 women) were reviewed. The participant’s average age was 38.6±13.4years. 1350 (66.1%) participants reported recurrent headache within the last 1 year. Of the total study population, the prevalence rate of primary headache was 1305 (63.9%). Number of people who suffered from migraine was 494 (24.2%), significantly greater in female than male participants (p=0.0001), with most frequent attacks at age 26-45 years. The risk of migraine associated with sex, education and family history (p=0.001). 592 (29.0%) of participants had TTH, mean age of them was 37.7±5.24, significant high rate in female than men, risk of TTH depends on education and job. The medication overuse headache was diagnosed at 116 (5.7%), 29.4% in men and 70.5% in women with average of 45.6±11.4 and 43±12.7 respectively. Among the participants 38.6% used medications, 28% people had one drug, 8.5% two drugs and 2% used three or more drugs. Use of non-steroid anti-inflammatory drugs (NSAID) made up major percent in headache patients. Increased frequency of medication and multidrug affected to medication overuse headache (p=0.008).@*Conclusion@#More than half of studied population had primary headache. Migraine was in 24.2%, TTH in 29.0% of people, and associated with sex, education and family history. Use of non-steroid anti-inflammatory drugs made up major percent in headache patients.
ABSTRACT
Over the last decade a large number of studies have investigated the possible adverse effects of ambient air pollution on birth outcomes. For preterm births the evidence as yet is insufficient to their infer causality. Our study goal was to study the associations between air pollution exposures during pregnancy and preterm birth for a 6 years period (January 2008 through December 31, 2013) in Ulaanbaatar, Mongolia. We used a logistic regression adjusting for gestational age, parental education level, parity and infant age. The preterm birth varied with maternal age, maternal education level, maternal pregnancy order and season after adjusting covariates. Young maternal age, maternal less education level, early and older birth order, spring season, not married status and higher number of pregnancy order t are risk factors for low birth weight. The correlation of preterm birth and air pollution was observed in the second and the third trimester of pregnancy. The preterm birth rates were associated with the average of combined air pollutants concentrations such us PM10, NO2 and SO2 in the preceding 6 weeks.
ABSTRACT
BACKGROUNDAir pollution issue has become the largest problem of Ulaanbaatar city in the last decade affecting health and wellbeing of its citizens. Air pollution levels are increasing considerably in winter as a result of coal burning by city dwellers living in ger areas. Our study purpose was to survey the impact of air pollution on infant health of Ulaanbaatar city in 2012.METHODSData of 7484 on births at Khan-Uul and Sukhbaatar districts residence mothers and infants of Ulaanbaatar city from 2012 and corresponding daily air pollution level data (CO, NO2, SO2 and PM10) from the Ulaanbaatar city air quality monitoring stations were used.RESULTSAir pollution levels in Ulaanbaatar city significantly affect birth outcomes. Exposure to high levels of СО2 of during the third trimester of pregnancy reduces newborn’s weight. Exposure to NO2 is not influencing to newborn’s weight. Mothers who lived in more polluted area during pregnancy period more likely had baby reduced weight in 44 grams.
ABSTRACT
Goal: The aim of the study was to identify economic burden from hypertention in Ulaanbaatar and develop some recommenadations. Material and Method: The top down approach was used to calculate direct costs of hypertension in five hospitals of the secondary and tertiary levels. To calculate cost of hypertension financial reports and cost centres data were used. A self-administered questionnaire was used to calculate indirect costs from the disease. Patients, admitted to six UB district and three tertiary level hospitals due to hypertension filled in the questionnaire. Data was analysed using SPSS 15 programme.Results: Some 114 patients were surveyed. The average cost of hypertension was 143914 ± 38189.5 (average bed days 8.7) and 264756 ± 40760.4¥ (average bed days 9.5) in the selected district and tertiary level hospitals respectively. The average cost for per out-patient visit was 4237 ± 2123.5¥ in the selected district hospitals and 3,162 ± 308.3¥ in the selected tertiary level hospitals. The indirect costs included transport cost to and from hospital, food, transport cost of relatives to visit them, cost of medications, and some other expenses related to their admission. Average indirect cost of an admission of patients with the hypertension was 253,395 and 212,717.44¥ in district and tertiary level hospitals respectively. Economic burden from temporary loss of working ablility due to hypertension was 177.1 millions tugrigs. National average wage was 300500¥ in 2009. Some 65.8% of respondents used antihypertension drugs at least once a day and average cost was 653.4¥ per patient per day. Annual and 10 years drug use estimates were 238491 and 2.3 million tugrigs per patient respectively (Inflation and price changes were not counted).Conclusion: Indirect and direct costs for admission were 1.1 billion (49.6%) and 939 million (42.5%) tugrigs respectively. Cost of hypertension in Ulaanbaatar was 2.2 billion tugrigs in 2009 and it is 1.1% of total health sector financing.
