The research on the smoking habits among 8th-to-12th grade students of schools was conducted using a random sampling method among the 13-18 years old school students.Materials and MethodsThe research was performed using a combination of both qualitative and quantitative methods. The quantitative part of the research was performed by conducting surveys among randomly selected secondary school students according to prepared and approved questionnaires. The qualitative study was performed by organizing focus groups based on prepared discussion guidelines. Sampling: the survey participants were students in grades 8-12 from both public and private schools in Ulaanbaatar, the capital city of Mongolia. A total of 1190 students from the 12 secondary schools of 6 districts were selected through random sampling.Resultsto the question of whether the participants have tried to smoke once or twice, 36,1% (407) responded positively. Among these respondents, 49.6% (272) are male and 23.2 (135) are female. This confirms the statistical data that male students are more exposed to the habit of smoking than female students (x2=57.8, p<0.01). The percentage of the currently smoking students is 11.2% (77) of whom 17.9% are male and 4.8% are female. Of the current smokers, 6.8% smoke every day (x2=48.3, p<0.01). The average age of taking up smoking was 14.0[±1.8] of which males students began using tobacco at 13.9[±1.8] years and females at 14.3[±1.6]. Among the smoking students, 10[±2.1]% were from public schools and 17.3[±2.8]% were from private schools (x2=8.1, p<0.01).

BackgroundThese study made us to investigate the drug row material of Mongolian traditional medicine such us Tribulus terrestris, Malva neclecta Wall and Eriocheir sinensis compounded preparation named “Malbus”. Investigated us preparations steel using for treatment of kidney and urinetract deseases, it is one of effective in Mongolian traditional drug preparations.Material and MethodsThe experimental protocol was approved by the Ethics Review Committee at the Ministry Health of Mongolia. In research we used 20 healthy mice and 60 Wistar rats. Investigation was based and implemented at scientific research laboratory of Traditional Medical Science Technology and Producttion Corporation and pathological laboratory of Institute Veterinary medicine. Chemically acting substances is steroid saponin content in Malbus compound was detected by using thin layerchromatography (TLC) and its value was determined by UV-spectrophotometry. The acute oral toxicity study was according to the method Prozorovsky (1978). The toxic nephrosis was produced using Gentamicin (80 mg/kg) rats by using Neugarten’s method (1983).ResultsThe ethanolic extract results of the phytochemical investigations showed that conteined in the “Malbus” determined the presence of bioactive substances such as flavonoids, steroid saponins. The ethanolic extract of Malbus was found to be LD50 of 16.3 g/kg. Toxic nephrosis was induced in Wistar rats administered preparation Malbus dose 80 mg/kg, 160 mg/kg, and 240 mg/kg. Blood levels of creatinine, uric acid, and urea were siginificantly reduced by Malbus treatment compared tocontrol. Histological study revealed that Malbus was effective for treatment of nephritis in rats induced by gentamicin.Conclusions:1. The ethanolic extract of “Malbus” compound determined the presence of bioactive substances such as flavonoids, steroid saponins.2.

Justification: Researchers highlighted an importance of health professionals’ participation (1), (2), a role on behavior change in primary health care services (3)evidence based health policy and program (4)(5) байгааг and health promotion to reduce a prevalence of both communicable and non-communicable diseases in Mongolia. Mongolian National University of Medical Sciences trains public health researchers and health social workers in the last ten years. It has been developed a guideline of required compulsory professional competence in which, students of SPH should acquire knowledge, skills including behavior change strategy and implement interventions, behavior change assessment at individual, family, group and community levels. Purpose: Aim of this research is to identify key words and content of "health Behavior" and "health Promotion" in undergraduate courses of School of public health (SPH) and compare with a content of compulsory professional competence requirements. Methodology and Materials: We used a summative content analysis [6] to identify key words and content of ‘’health behavior’’ and ‘’health promotion’’ in 140 courses between 2009 and 2016 and compared with 17 required compulsory professional competence in blue print guideline [7]. Results: Planned academic hours of ‘’health behavior and promotion’’ in courses of health social work was insufficient and they covered several theories with no content of implementation, application, evidence based practices and examples. For students of public health researchers, there are required compulsory 8 skills of health behavior, however skills and knowledge were slightly covered in courses of ”food safety”, “health of kids and adolescent” and “occupational health”. Conclusion Undergraduate courses for health social workers and public health researchers were based solely on “individual health behavior theories’’. The included content of the theory, application of organization and community behaviors was insufficient in the existing “health behavior” course.

Rationale: Carbon monoxide (CO) is a colorless, odorless gas produced by carbon-containing substances, most commonly incomplete fuel and biomass combustion. Carbon monoxide deprives the human body of oxygen, leads to severe poisoning and death. In 2017, there were 137 new cases of carbon monoxide poisoning per 1,000,000 people worldwide, and 4.6 deaths per 1,000,000. The global incidence of carbon monoxide poisoning has remained steady over the previous 25 years, while mortality has decreased by 36-40%. Every year in Mongolia, 700-840 persons are hospitalized for carbon monoxide poisoning. Also, there has been a lack of study into the prevalence and causes of carbon monoxide poisoning and death. Goal: Study the dynamics of morbidity and mortality cases caused by carbon monoxide poisoning in Mongolia. Objectives:
To analyze the carbon monoxide poisoning morbidity recorded in Mongolia between 2016-2020.
To analyze the carbon monoxide poisoning mortality reported in Mongolia between 2016-2020. Material and Methods: The survey was conducted utilizing data from outpatient and inpatient poisoning and deaths reported in 2016-2020 with the goal of studying carbon monoxide poisoning and mortality in Mongolia. Workplace exposure poisoning was excluded from quantitative data on carbon monoxide poisoning (fires, suicidal, accidental and domestic explosions, accidents, external effects).The statistics analysis was performed using 23 versions of the SPSS program, to estimate a distribution of new cases and fatalities per 10,000 population depended on age, sex, average number of hospital days, and standard error. ArcGIS version 10.8 was used to map the locations. Results: Acute carbon monoxide poisoning. Carbon monoxide poisoning was 0.01-0.31 cases per 10,000 population during 2016 and 2018. Between 2019 and 2020, it increased to 1.5-1.9 cases per 10,000 population, with up to 37% of those admitted to hospitals. In the last five years, carbon monoxiderelated deaths have been reported in 0.1-0.3 cases per 10,000 population. The amount of hours firing of the households increases every year in September, when the colder season begins. Incidences of death and intentional poisoning were reported in Arkhangai, Uvurkhangai, Khuvsgulaimags, and Ulaanbaatar. The average age of poisoning patients admitted to the hospital was 33 ± 19.5 years old (minimum 2 months, maximum 81). In terms of gender, women registered for 58.4 (734) percent of all cases. The average number of days spent in the hospital was 3.4± 3.7 days.
Carbon monoxide poisoning-related mortality. During the previous five years (2016-2020), 353 people died in Mongolia as a result of carbon monoxide poisoning, although 1.4 percent, or five people, died in hospitals, one case in Bayan-Ulgii, Zavkhan, and Uvs aimags, and two cases in Ulaanbaatar. However, 98.6 percent of them died prematurely at home or in poisoned places due to a lack of access to health care. The average age of carbon monoxide poisoning deaths cases was 35 ± 19.9 years old, and 71.7 (253) percent were male. The Ulaanbaatar, Selenge, Uvs, and Dornod aimags had the lowest death rate of 0.08-0.21 per 10,000 population, while Khuvsgul and Arkhangai aimags had the highest death rate of 0.96-1.57 per 10,000 population. Conclusions Carbon monoxide poisoning among the population rises during the winter season, however, in the previous five years, 96.5 percent of cases have been poisoned accidentally, particularly 82.6 (1035) percent of cases reported in Ulaanbaatar. According to socioeconomic factors, 41.6 (529) of the cases were male, with an average age of 36.5±15.4 years.
During the preceding five years, carbon monoxide-related mortality in Mongolia was between 0.2 per 10,000 people. Without medical attention, 99.2% of cases died at the exposed location or area. The death rate in Khuvsgul aimags was low, whereas it was high in Ulaanbaatar city. The average age of premature deaths was 35±19.9 years, and 71.7 (253) percent were male.

Introduction: Beginning 15 May 2019, the consumption of raw coal in Ulaanbaatar has been replaced by the consumption of briquette fuel for the improvement of air quality according to Governmental Resolution No.62 adopted in 2018. Since after this resolution has been in placed the number of CO poisoning has been increased as of 18 December 2019, nine persons were died and 1394 people get a health care service due to CO poisoning. However, it has been not been assessed briquette affect to the indoor air quality and its health impact. Thus, it is need urge to define the indoor air quality effect of briquette and its heath impact. Goal: To assess the indoor air quality of the household using the “improved briquette” and identify the causes of the risk. Material and Method: This a cross-sectional survey, conducted from January 31, 2020 to April 31, 2020, data were obtained by quantitative, qualitative (observation, interview) and direct indoor air quality measurement. The survey sampling frame was 40 households in central 6 districts of Ulaanbaatar that used improved fuels (20 households with a history of carbon monoxide poisoning and 20 households that were not affected), and 14 households in the Nalaikh district that used raw coal, in total of 54 households were participated. Indoor air quality was measured by PM2.5, PM10, CO, SO2, NO2, and microclimate per household for 24 hours during a week.
The statistical data analysis was done by the SPSS-23 program and preformed required parametric and non-parametric tests. The normality of the data was checked by the Kolmogorov-Smirnov test. The most of data was not normally distributed. So, thus we used median and used relevant non-parametric tests. The average level of microclimate indicators, and air quality indicators were defined as mean, median and its IQR and standard deviation. The 95% confidence intervals of mean and frequencies were determined and used to differentiate group differences.
The Ethical permission to start the survey was approved by the 2nd meeting of the Ministry of Health on February 4, 2020. The committee was reviewed and approved the research methodology based on whether data collection technique and tools are considered the ethical issues, and whether provided accurate information for make decisions to enroll to the survey for respondents. Results: According to the health statistic, from October 2, 2019 to March 31, 2020, a total of 2,768 people from 837 households were exposed to carbon monoxide poisoning. Of the total reported cases, 10 were drunk, and 2 were due to other disease complications, and a total of 2,756 cases were confirmed diagnosis as carbon monoxide poisoning.
Emissions of CO were recorded every 15 seconds and the results were calculated by conducting continuous measurements per household for 24 hours a week. The level of CO emitted into the indoor environment of households exposed by carbon monoxide had increased during the following time from 7 am to 9 am in the morning, from 13 pm to 15 pm, from 18 pm to 20 pm in the evening, and from 22 pm to 24 pm at night. During this period of time, the indoor air CO level had increased from the WHO mild poisoning recommendation level. Conclusion It has been defined that the carbon monoxide emits to the indoor air households which are using an improved fuel according to measurement the 30 minutes, 31-60 minutes, and 61-120 minutes after burning.

ABSTRACT. Recurrent aphthous stomatitis, or RAS, is common oral disorder of uncertain etiopathogenesis for which only symptomatic therapy is available. This article reviews the current clinical features of RAS among study patients and the result of therapeutic effects of the herbal preparation Akhizunber. Over the past four years we have treated 61 RAS patients with different clinical forms by herbal preparation Akhizunber or Alumekatin. The distribution of clinical forms RAS RAS among study patients were minor aphthae -75.4%, major aphthae -16.4% and herpetiform ulcers -8.2% respectively. The healing time of treated Akhizunber was in minor aphthae -9.28±4.82 days, major aphthae -14 days and herpetiform ulcers -12 days. Of the total study participants, the patients treated by Akhizunber reported a rapid and complete recovery from RAS during treatment compared with treated patients by Alumekatin. Treatment with herbal preparation Akhizunber can be effective for patients suffering from RAS in any clinic form, regardless of their ulcer number and size.

BACKGROUND. Over 5% of the world’s population or 466 million people have disabling hearing loss (432 million adults and 34 million children). Profound sensorineural hearing loss and deafness can be treated successfully with a cochlear implant. A cochlear implant (CI) stimulates the auditory nerve, bypassing the defective cochlea, and provides auditory information to the developing brain, thus improving oral language. Children, who receive an early diagnosis of deafness and proper speech rehabilitation, and undergo early cochlear implantation, are able to develop auditory and linguistic skills at par with their hearing peers. METHOD. 6 deaf patients who underwent unilateral Cochlear Implantation at the NCMCH from January 2017 to June 2018 were included in the study. Participants were divided into 3 groups on the basis of age at which participants underwent implantation. RESULTS. Pre-op average MAIS was 1,6/40, Category of Auditory Performance (CAP) - 0,77 and SIR - 0,7/5 in all implanted age groups. Score increased over time to attain average score MAIS -29.6/40, CAP- 3.3/7 SIR-2.7/5 in all implanted groups at one year after implantation. CONCLUSION. There is a need for more research on patient age and gender composition, and outcomes of cochlear implantation and hearing devices in this study population. A robust set of study measures would provide statistical significance. Parent-child relationships affect hearing and speech therapy results, so there’s a need to improve parents’ knowledge regarding these therapies.

Introduction: This field assessment was performed to ensure the effective implementation of Order No. A/142 of the Deputy Prime Minister of Mongolia dated 30^th December 2021 and Order No. A/01 of the Head of the National Committee for Reducing Environmental Pollution dated 3^rd January 2022 and to monitor the level of indoor air pollutants emitted from traditional stoves and standard stoves. Purpose: To determine the level of indoor air pollutants emitted from briquette combustion and to develop recommendations by comparing various types of stoves and dwellings. Materials and Methods: Through analytical cross-sectional designs, three households from Songinokhairkhan district and one household from Chingeltei district were selected to participate in this assessment as they use briquettes for heating, vary in their dwelling types (ger (traditional Mongolian tent), house) and their stove types (traditional, standard), stay home during the day and chose to participate in the assessment. 24-hour continuous measurements were conducted for each dwelling and before taking measurements, we calibrated and adjusted the air suction velocity of the measuring instrument at the Central Metrology Laboratory. The monitor was placed at a distance of 0.5m from the stove and a height of 0.5-1.0m from the floor. The results were then compared with the Mongolian National Standard “General air quality and technical requirements MNS4585:2016” and WHO Guidelines for Indoor Air Quality 2021. Statistical analysis was performed using SPSS 24.0 software, mean, ANOVA test, and if the p-value is less than 0.05, our results are statistically significant. Results: The concentration level of SO₂ in houses with “Dul” stoves was within the level specified in the Mongolian standard MNS4585: 2016 and WHO Guidelines for Indoor Air Quality 2021, while 24-hour SO₂ concentration in gers and houses with traditional stoves was 1.3-2.92 times higher than the standards. The 24-hour average concentration of nitrogen dioxide in houses with traditional stoves was 1.73 times higher than the Mongolian air quality standard MNS4585: 2016. There were statistically significant differences in the emission levels of SO₂ and NO₂ depending on dwelling and stove types (df=4, f=4.04, p=0.008 and df=4, f=17.17, p=0.001, respectively.). The 8-hour average (10,000 μg/m3) CO concentration was statistically significant for various types of dwellings and stoves (df=4, f=45.17, p=0.001), whereas there was a statistically significant difference in CO concentrations in gers with traditional stoves and gers with standard stoves in terms of morning, afternoon, and evening hours (df=3, f=33.17, p=0.001). Conclusion Indoor air pollutants in the households except for houses with “Dul” stoves have been determined to exceed the air quality standards set by the Mongolian air quality standards and WHO Guidelines for Indoor Air Quality 2021.
