RESUMO
Background@#The shapes of the eye and upper eyelid are distinctive facial landmarks. The palpebral fissure is composed of the free edges of upper and lower eyelids the lateral and medial canthus. Many researchers confirmed that the morphometric characteristics of the palpebral fissure, canthal distance and exophthalmometirc value (EV) vary according to race, ethnicity, age and sex and normative values which may serve as a reference in the index population. Knowledge of normal dimensions, the existence of asymmetry of the palpebral fissure is of value in several clinical specialties including ophthalmology, plastic and reconstructive surgery and traumatology, where it plays a part in the patient evaluation, management and outcomes.@*Methods@#This cross-sectional study was conducted in the Ophthalmological Department, Third State Central Hospital between January 2022 and August 2022. We included participants who are above 18 years, no history of congenital or traumatic craniofacial deformities, any orbital fractures, tumors and surgeries. All measured values that represent eyelid shape and EV were calculated by mean and standard deviation for statistical analysis.@*Results@#A total of 103 participants aged 19-86 were included in the study, of which 44 (42.7%) were male and 59 (57.3%) were female. The distance between the lateral and medial canthus ranged from 20 to 35 mm, and the mean of the right and left side was 28.30+3.23 mm and 28.05+2.99 mm, respectively (p=0.561). The palpebral fissure height ranged from 5 to 13 mm, and the mean of the right and left side was 8.85+1.65 mm and 8.80+1.65 mm, respectively (p=0.816). The mean distance between the lateral canthi were 90.39+5.57 (range: 80-105 mm), whereas the mean distance between the medial canthi were 63.75+4.25 (range: 53-73 mm). The orbital height varied between 27-43 mm (33.73+3.72) and 26-44 mm (33.78+3.73) on the right and left sides, while the orbital width varied between 26-47 mm (36.75+4.53) and 27-45 mm (36.72+4.42) on the right and left sides, respectively. When measuring the exophthalmometric value (EV), the axial position of the eyeball, with the Hertel’s exophthalmometer, it ranged from 8 to 20 mm on both sides (mean value 13.68+3.01 and 13.71+3.00 on the right and left sides, respectively), and there was no statistically significant difference in symmetry (p=0.94).@*Conclusion@#The results are determined different from the findings of Chinese, Korean, Afro-American and Caucasian population based studies. Thus further evaluation is required to represent the normative value of Mongolian index population, that is highly beneficial for clinical assessment, diagnosis and management.
RESUMO
Background@#TED (thyroid eye disease) is an inflammatory disease of the orbit caused by autoimmune diseases of the thyroid, which adversely affect the vision, appearance, and quality of life. Exophthalmos and eyelid retraction are the main features of TED, which can lead to ocular motility, diplopia, optic neuropathy, and permanent vision loss. The study aims to determine the most common clinical signs of TED in Mongolians and define whether there is a correlation with the levels of thyroid autoantibodies.@*Methods@#The study involved 102 patients with TED and 81 patients with Graves’ ophthalmopathy. The clinical features of TED were identified and evaluated by activity score (CAS) and severity of GO using the European Group of Graves’ Orbitopathy (EUGOGO).@*Results@#The mean age of TED patients was 42.6±11.2, which was younger than GD patients (P=0.012). The current smoker was 24 patients (23.5%) with TED, which is relatively higher than GD (P=0.0001). The most common ocular signs were eyelid retraction 80 (78.4%), proptosis 77 (75.5%), diplopia 14 (13.7%) and 4% vision loss. There were no differences in proptosis between the right (18 mm, median) and left eye (17.8 mm, median) (P>0.05). The mean CAS score was 3.09±1.72 and varied depending on gender and smoking. According to EUGOGO, 62.7% of the patients were moderately severe. Only 7 % of the patients were in the sight-threatening stage, presenting optic neuropathy and corneal breakdown. The mean TSI level in patients with TED was 37.95 ± 35.41 IU / ml, which was 2.7 times higher than the mean in patients with GD.@*Conclusions@#Eyelid retraction and exophthalmos are the most common clinical signs of TED. Early diagnosis of these features can prevent complications of the disease. Determining serum TSI levels will help in the treatment and monitoring of TED.
RESUMO
Background@#Globally the incidence of stroke is not decreasing, and the deaths and disabilities caused by stroke is increasing every year, especially in low and low-middle income countries.</br> Long-term trends in stroke incidence in different populations have not been well characterized, largely as a result of the complexities associated with population-based stroke surveillance.</br> Having reliable data on stroke morbidity and mortality, as well as periodic identification of long-term trends will be important information for proper prevention planning in the population, monitoring the disease and further improving the quality of health care. @*Material and Method@#A prospective cohort study has been conducted in adult citizens (972409 in 2019, 925367 in 2020) of 6 districts of Ulaanbaatar from the 1st of January, 2019 to 31st of December, 2020. All first-ever and recurrent stroke cases were included using special software, developed for stroke registry, based on the WHO STEPS approach from participating radiology departments of state hospitals, district hospitals, and some private hospitals. Information of stroke death was obtained from forensic institute and state registration office of the capital city.</br> The trends of stroke incidence and mortality was compared to data between 1998-1999 and 2019- 2020 in UB. @*Results@#The age-standardized crude incidence rate per 100.000 person-years of stroke were 209.0/100.000 (n=1934) in 2019 and 194.0/100.000 (n=1821) in 2020 among adults of UB city. The above results were compared to 1998-1999 studies and the incidence rate declined by 94.0/100.000 in 2019-2020, whereas mortality rate increased by 10.0/100.000 in women aged 16-34. Stroke mortality was 11.6% in 1998 and 26.5% in 1999, while in our study it was 33.87% in 2019 and 29.71% in 2020. Although the incidence of stroke rates has decreased in 1998-1999, the mortality rate has not decreased significantly. @*Conclusion@#Morbidity and mortality rates among the population of Ulaanbaatar citizen remain highest in the world, compared to 20 years ago with overall morbidity declining but mortality has not decreased. </br> In recent years, the Government of Mongolia has been focused on reducing non-communicable diseases, but the primary and secondary prevention and control of stroke in the general population, as well as the acquisition of knowledge attitudes, practices and access to health care still need to be improved.
RESUMO
Background@#Stroke is one of the leading causes of mortality and disability worldwide. Understanding sex differences in risk factors, clinical characteristics and death after stroke might provide valuable evidence for prevention and management of stroke. @*Aim@#We aimed to describe sex differences in risk factors, clinical characteristics and death after intracerebral hemorrhage (ICH) and ischemic stroke (IS) using hospital-based registry in 6 districts of Ulaanbaatar, Mongolia. @*Materials and methods@#We used hospital-based stroke registry in Ulaanbaatar Mongolia. From 2019 to 2020, total of 974 patients with acute ICH and 1612 patients with acute IS were enrolled in this study. The severity of stroke was measured by National Institutes of Health Stroke Scale (NIHSS) and Glasgow Coma Scale (GCS). Risk factors for stroke were defined as patient’s history and their medical record. Death after stroke was registered at 28 days and 90 days by follow-up study. A comparison of categorical and continuous variables was analyzed using chi-squared test, Student’s t-test and Mann Whitney U test. Univariable and multivariable logistic regression analyses were also performed.@*Results@#The mean age of ICH patients was 58.41±11.56. There was significant difference in age (59 vs 57, p=0.009) between women and men. Men with ICH were more likely to drink alcohol (35.4% vs 5.2%, p=0.000) and to smoke (37.0% vs 8.4%, p=0.000) and to have arterial hypertension (72.7% vs 58.6%, p=0.000). However, there were no significant differences in other risk factors including atrial fibrillation, diabetes mellitus, prior stroke and other cardiac diseases. There were no sex differences in clinical characteristics including systole and diastole blood pressure, NIHSS scores and GCS. In our study, case fatality rate was 23.8% at 28 days and 1.9% at 90 days after ICH. By multivariable regression analyses, there were no significant association between sex and death at 28 days and at 90 days (OR:0.74; 95% CI:0.52-1.06, OR: 0.80; 95% CI:0.29-2.21).</br> The mean age of IS patients was 61.07±12.88. The women were older (63 vs 59, p=0.000) than men. Men with IS also were more likely to be current smokers (37.6% vs 9.0%, p=0.000), current drinkers (33.2% vs 3.4%, p=0.000) and to have arterial hypertension (74.7% vs 65.9%, p=0.000). There were no significant differences in other risk factors. For IS patients, there also was no sex difference in clinical characteristics. Case fatality rate was 13.3% at 28 days and 1.1% at 90 days after IS. By multivariable regression analyses, there were no significant association between sex and death at 28 days and at 90 days (OR:0.90; 95%CI: 0.64-1.26, OR:5.16; 95%CI: 0.99-23.9). @*Conclusion@#Our study showed sex differences in some vascular factors of both stroke subtypes which emphasized that we need to implement stroke prevention targeting sex-specific risk factors. While clinical characteristics and early mortality of intracerebral hemorrhage and ischemic stroke were not differed by gender.
RESUMO
Background@#Stroke is still one of the leading causes of morbidity and mortality worldwide. Registry-based data of stroke are scarce in low and middle-income countries such as Mongolia. We aimed to investigate the incidence and mortality of stroke in adult population of UB Mongolia by stroke registration method. @*Material and Method@#Covering 611265 (≥15 years old) adult citizens of three districts of Ulaanbaatar, a population-based prospective study was done from the first, January of 2019 to 31st, December of 2019. All first-ever and recurrent stroke cases were included using special software, developed for stroke registry, based on the WHO STEPS approach from participating radiology departments of state hospitals, district hospitals, and family clinics. Information of stroke death was obtained from forensic institute and state registration office of the capital city. @*Results @#In a 1-year study period, 1068 (women 39.1%) stroke cases were registered in people with 60.16±13.66 years old. Stroke incidence rate was 169.81/100000 including first-ever and recurrent events. Stroke incidence rate was higher in men and people with 80 and above years old. The ratio between IS and ICH was 1.14:1.0. Stroke mortality was 27.1% and mortality rate was 45.94/100000. The highest rate mortality was in ICH subtype, male population and older people. @*Conclusion@#We identified relatively high incidence and mortality rate of stroke in ICH indicating an urgent need for improvement of arterial hypertension control, health education and primary prevention mainly among men.
RESUMO
Background@#Stroke is a leading cause of death and disability, especially in low-income and middle-income countries and it impacts a tremendous medical, emotional and fiscal burden on society. Due to advances in Western healthcare, the prevalence of stroke since 1970 has decreased by 42%, whereas it has more than doubled in low-income to middle-income countries. </br> Stroke is a heterogeneous, multifactorial disease regulated by modifiable and nonmodifiable risk factors. Approximately 80% of stroke events could be prevented by making simple lifestyle modifications. In fact, nationwide characterization of well-known stroke factors in all social backgrounds is essential, however; populations can differ significantly not only in their socio-behavioral, legal, and geographical conditions, but also from other, historically understudied. Therefore, it is crucial to determine characterization of risk factors for ischemic stroke among Mongolian population.@*Objective@#To determine etiology and risk factors for ischemic stroke among Mongolian population@*Material and methods@#Our study was conducted by case-control study design. Cases were patients with acute first stroke; controls were matched with cases, recruited in a 1.2:1 ratio, for age and sex. The case series study was conducted in Stroke center of Third State Central hospital from January 2017 to December 2017. Structured questionnaires were administered and physical examinations were done in the same manner in cases and controls. Self-reported history of hypertension and diabetes mellitus or blood pressure of 140/90 mm Hg and blood sugar 6.4 mmol/L or higher was used to hypertension and diabetes mellitus, respectively. Smoking status was defined as never, former, or current smoker. Alcohol use was categorized into never or former, low intake, moderate intake, and high or episodic heavy intake. Atrial fibrillation was based on previous history, review of baseline electrocardiograph results (for cases and controls). Odds ratios (OR) and logistic regression were calculated, with 95% confidence intervals. @*Results@#In total, 173 patients with ischemic stroke and 146 controls were included. The patients’ age ranged from 17 to 92, the mean age was 61.2. Ischemic stroke more frequent in man than women by 27.4%. Previous history of hypertension or blood pressure of 140/90 mm Hg or higher (OR 2.40, 95% CI 1.48-3.88), diabetes mellitus (OR 3.08, 95% CI 1.44-6.57), hyperlipidemia (OR 5.09, 95% CI 2.64-9.82) atrial fibrillation (OR 8.70, 95% CI 2.01-37.64 ), current smoking (OR 2.07, 95% CI 1.26-3.40), alcohol consumption (OR 4.75, 95% CI 2.58-8.73) were all significantly associated with ischemic stroke. The mean age was lower in patients with stroke of other determined etiology. The frequency of hypertension was higher in patients with lacunar infarct than other subtypes. Smoking was high frequent in patients with large artery atherosclerosis.@*Conclusion@#6 potentially modifiable risk factors were collectively associated with ischemic stroke and were different among ischemic stroke subtypes. The odds ratios of these risk factors are higher than other countries’ study.
RESUMO
BackgroundIn the worldwide, each year registered about 357 million new cases of sexual transmitted diseases.39 % of all infectious diseases were STI diseases in Mongolia in 2013 and which also 56.8 % of totalinfectious diseases Dornod province.ObjectiveTo investigate sexual transmitted diseases among the population of Dornod province and its commonrisk-factors.Materials and MethodsIn the survey were chosen 600 persons which is aged from 15 to 64 by random selection methodand divided into 6 cluster and each cluster had 100 persons. In the survey attended 300 male, 300female.ResultsThe survey respondents were married 59.1%, 50.7% of the employed, and 49.3% of the unemployed.2,1% of the survey population has already been tried drug abuse, but in the group of age 15-24,indicate level of the knowledge about drug abusing is very low which is 29,4%, a little or less knowabout drug abusing 35,6%, not know about drug abusing 35%. In other hand beverage usage levelwas very high which is 67% and 51,3% is using an alcohol in the last year constantly.Examination of specialized doctors 38.3% were suspected of sexual transmitted infections. Theyincluded laboratory testing.The 4.9 percent of total respondents had sexually transmitted diseases. It were syphilis 57.1%,gonorrhea 10.2%, trichomonasis 6.1%.The 83 percent of total respondents had sexual intercourse. The average age of first sexualintercourse was 18 ± 1 (95% CI 16.8 - 19.1), 7.1% had two or more sexual partners. Men had toused alcohol while sexual intercourse was 32.1 percent. Women were 49.2 percent and 38.5 percentof people infected with sexually transmitted diseases not use condoms during sexual intercourse.Conclusion1. One in 20 people surveyed, women aged 15-24 and men aged 35-44 have sexual transmissioninfection.2. Risk factors are had two or more sexual partners, had to used alcohol while sexual intercourseand using condoms during sex with casual partners are not enough.
RESUMO
BACKGROUND:Our previous study has shown that the prevalence and structure of the neurohereditary diseaseswere different by provinces and some form of these diseases as “indigenous” in some isolatedpopulation. There are some scientific results of our researches–genetics about consanguineous,which is more potential factor of community is some area of Mongolia. All these circumstance isgiving to carry out this study.MATERIALS AND METHODS:We used descriptive epidemiological method for revealing hereditary neurological diseases in thepopulation of 6 provinces (aimags) of Mongolia: Dornogobi (Easth-gobi), Sukhbaatar, Gobisumber,Central aimag, Bulgan, and Darkhan-Uul. Total population of these provinces is 363072. Thenumber of population in 6 provinces was fluctuated in the range from 15.000 (Govisumber) to 88.875(Darkhan-Uul). Prevalence was accounted for 100.000 populations.RESULTS:The prevalence of neurohereditary diseases makes up 17.08 cases per 100.000 populations amongthese 6 provinces. 79% of these are hereditary neuromuscular diseases i.e 49 patients from 29families. Myotonic dystrophia and genetic neuropathies Charcot-Marie-Tooth have comparativehigh prevalence over test forms of disease.The high rate neurohereditary diseases was established in the population of Bulgan (35.80•10-5),Sukhbaatar (31.17•10-5), and Dornogobi (21.33•10-5) provinces. Their prevalence’s prevailed in the7-10 times over rates Darkhan-Uul, 3-5 times over rates of Gobisumber aimags.No neuromuscular forms of neurohereditary diseases i.e spastic paraplegia (11.3%) andspinocerebeller ataxia (9.68%) accounts for 21% among all forms of neurohereditary diseases.The prevalence of neuromuscular diseases in the population of these six provinces is two times highthen the average rate of the population of Russia (1980 years). First reason is may be associatedwith high predisposition of based on consanguineous through reproductive way in some of theseprovinces of Mongolia.

RESUMO
Background. The prevalence of hereditary spastic paraplegia or Shtrumpel disease is very various in studied countries of the world. It fluctuated between 0.43 (Bulgaria) and 72.4 (South African Republic) per 100’000 population.Method. In this study which is a part of a general epidemiological study of some hereditary neurological diseases in Mongolia since 1997, authors established the prevalence of myotonic dystrophy among 1.7 million population from 14 aimags and the capital city Ulaanbaatar during the period from 1997 to 2010.Goal. The study aimed to establish the prevalence of hereditary spastic paraplegia (HSP) in Mongolia.Material and Method. This study is part of a general study of the epidemiology of hereditary neurological diseases in population of 14 aimags (provinces) and the capital city Ulaanbaatar (the total population covered by the study was 1’738’000) which is being carried out since 1997. The sizes of population in aimags and the city ranged from 47,800 (Southgobi) to 605,292 (Ulaanbaatar). This study report extrapolates the prevalence nationwide. Diagnosis was established by mainly clinical characteristicsResult. Study revealed 47 patients from 15 families. The prevalence of HSP by aimags was established from 0 to 13.48 per 100’000 population (Uvs aimag). The average nationwide prevalence (1’700’000 above) was established at 2.70/100’000. There are revealed 9 cases (19.1%) in ages of 0 and 14, 6 cases (12.8%) in ages of 14-19, 27 cases (57.5%) in ages of 20- 49 and 5 cases (10.6%) in age above 50.Conclusion1. By prevalence of HSP Mongolia belongs to countries with average prevalence. But the prevalence rates differ by aimags. Patients with HSP in Ulaanbaatar (11 cases) were covered by molecule-genetic analysis by types of the disease, revealing occurrences of II and IV subtypes. 2. Of all patients, 90% are below 50 years of age pointing to the early morbidity with this disease in the context of their early mortality. The situation reveals the need of further moleculegenetic and clinical studies of the types of this disease and of improvement of clinical and genetic counseling of HSP patients.
RESUMO
Backgroundв Previous the prevalence of myotonic dystrophy was identified very rare, because of the poor diagnostics. In fact, due to getting high quality of diagnostical equipments the disease is determined very common among people in the world. According to some researchers’s statistical data during 1980-1990 years, the prevalence was 1.1 in England, 2.4 in South Ireland, 5.0 in Switzerland per 100.000 population.Goal. The study was aimed to establish the prevalence of myotonic dystrophy in MongoliaMethod. In this study which is a part of a general epidemiological study of some hereditary neurological diseases in Mongolia since 1997, authors established the prevalence of myotonic dystrophy among 1.7 million population from 14 aimags and the capital city Ulaanbaatar during the period from 1997 to 2010.Results. The prevalence by aimags was ranged from 0.0 to 27.06 per 100.000 population. The average nationwide prevalence is 5.63 per 100.000. Several aimags, especially Gobi-Altai, Orkhon and Khuvsgul are high prevalence with over 3-5 times the average. But in Dornod, Bayan-Ulgii, Dundgobi, Zavkhan, Uvurkhangai, Khentii aimags didn’t have a case of myotonic dystrophy in their population. The rest of aimags have a prevalence from 2.45 (Uvs) to 5.0 (Ulaanbaatar) per 100.000 population.Conclusion1. The relatively high prevalence of myotonic dystrophy was determined among the Mongolian population, especially in Gobi-Altai, Orkhon and Khuvsgul aimags with over 3-5 times the average. 2. The disease is spreading through reproductive way in some isolated populations. There is also a trend of increasing incidence of the disease in urban areas apparently through mechanic way rural to urban migration. 3. The study concludes that there is a need of more intensive response to fight and prevent this disease through upgrading to the modern neurological and genetic diagnostics of the disease, and their regular and sustainable application. Consequently, there is also should be need to create and improve clinical and genetic counseling for patients with this disease.
RESUMO
Background: The data of prevalence of epilepsy in rural provinces among general population in Mongolia is rare. Goal:The study aimed to identify prevalence rate of epilepsy and its characteristics by age and sex among the population in eight provinces (Bayan-Ulgii, Bayankhongor, Gobi-Altai, Zavkhan, Uvurkhangai, Dundgobi, Orkhon and Hentii) of Mongolia.Material and Мethod: This study in the listed aimag populations was carried out by retrospective application and using a questionnaire developed according to a methodology approved by the Academic Council of the Medical Science Institute. For verification of the epilepsy diagnosis, the study based on neurologist examination and EEG. In some suspect cases we used neuroradiological tests including СT and MRI. The diagnosed patients were registered using a special form. The study involved diagnostic examinations of 627762 (306482 males; 321280 females) persons that had at least two unprovoked seizures in their lives. For each case of positive diagnosis we calculated the prevalence rate per 1,000 population in each category of extended age groups (1-12 months, 1-2, 3-4, 5-6, 7-8, 9-10, 11-12, 13-15, 16-17, 18-22, 23-27, 28-32, 33-37, 38-42, 43-47, 48-52, 53-59, and above 60) and by sex.Result: There were 1407 cases (785 males; 622 females) of diagnosed epilepsy among the studied population. The cumulative prevalence rate for all aimags was studied 2,24 (males- 2,56; females-1,93) per 1,000 population. The relatively high prevalence rates per 1,000 population were observed in Gobi-Altai (5,14), Dundgobi (3,31), and Orkhon (2,48) whereas the lowest rate was in Bayankhongor (1, 38). A differential look by sex reveals a high sex gap 6,20 for males and 4,12 for females in Gobi-Altai while Dundgobi (males- 3,84; females- 2,80), Orkhon (males-2,91; females-2,08); Uvurkhangai (males -2,20; females -1,73) show little difference by sex (P>0,05).As for the differences by the detailed age groups, all aimag data shows that prevalence for males ranges between 0,14(1- 12 months) and 5,17 (48-52) and for females between 0,24 (above 60) and 3,82 (38-42). The highest prevalence rate among male population was observed in 48-52 age group, 6,21/1000; followed by age groups 33-37 (2,93/1000); 53-59 (2,84/1000); 38-42 (2,81/1000); and 18-22 (2,38/1000). The highest prevalence rate among female population was observed in 43-47 age group 5,49/1000 followed by 38-42 (5,48/1000); 33-37 (4,0/1000); 53-59 (3,35/1000).Epilepsy prevalence in age groups younger than 11-12 tends to fall for both male and female population. Gender difference in prevalence is that males tend to have higher rates 2,56 than females 1,93 ( P<0,05).Conclusion:1. The general epilepsy prevalence among some rural populations in Mongolia is 2,24 (M -2,56; F-1,93) per 1,000 population.2. The cumulative by all studied aimags data reveal relatively high prevalence rate in age groups of 18-59. This level might be related to men’s vulnerability to traumas and factors of vascular origins while in women it might relate to their physiological transformations of pregnancy delivery and menopause.3. Epilepsy prevalence in age groups under 12 years old tends to fall for both male and female population which might be related to the low level of examination and diagnosis of these diseases among children.4. Compared to some foreign scholars’ data, Mongolia’s epilepsy prevalence rate does not qualify it among the high rate countries.
RESUMO
BACKGROUND:The prevalence of overweight or obesity in populations has increased in recent decades in developed countries.The results of Mongolian Steps Survey on the Prevalence of Noncommunicable Disease Risk Factors revealed that21.8% were overweight and 9.8% obese in 2006.Overweight and obesity lead to serious health consequences such as: cardiovascular disease, diabetes mellitus andsome types of cancer.Overweight and obesity is defined as an excess body fat content for statur (Bray GA, Bouchard C, James WPT. 1998).Ideally, the best assessment of overweight and obesity would be a measure of actual body fat (Deborah A, Galuska andLaura Kettel Khan, 2001). Therefore, the aim of this study was to explore the association between overweight or obesityand body fat mass and body- fat percentage levels in Mongolian people.GOAL:The goal of this study was to explore the body fat mass and body fat percentage in Mongolian people by the categoriesof gender, age groups and body mass index categories.MATERIALS AND METHODS:This study was conducted from April 2008 to April 2009 in Ulaanbaatar Songdo Hospital. We were chosen 240 peopleaged 16 to 80 years by the random sampling method.Height was measured using the Ultrasonic Height meter ‘’UHM-101’’ (Jawon Medical Co.Ltd, SK). Body mass index,body fat mass and body fat percentages were measured using a segmental bioelectrical impedance meter (‘’X-SCANPLUS II+Body Composition Analyzer, Jawon Medical Co.Ltd, SK). The percentage of body fat and body-fat mass weredescribed in regard to age, sex, weight and height of an individual.RESULTS: The survey results on BMI categories (WHO 2000), 39.6% had normal weight while 35, 8% were overweight and were15.8% obese I, 7.1% obese II, and 1.7% obese III, respectively. The percentage levels of body fat were 27-31% in malesand 33 - 42% in women aged 39-70 years.Body fat mass and body fat percentage levels were high in population with overweight and obesity.The daily consumption of fat was higher than the Mongolian RDA.CONCLUSION: Body fat percentage levels and body fat mass were increased with age and BMI categories.
RESUMO
BACKGROUND: Multiple sclerosis is spreading in population of Mongolia last 30 years. But there are rare of the date ofprevalence of this disease in Mongolia. So we have studied the prevalence of this disease in population of 8 provinces(aimags) of Mongolia in 2008 year.GOAL: To reveal and establish prevalence and clinical characteristic of multiple sclerosis (MS) in population of 8 aimags(provinces) of Mongolia.METHOD: Revealing of patients with multiple sclerosis in population was made by neurologists, which are possessedof clinical method for revealing or confirm the diagnosis and were taken in register the patients only with confirmeddiagnosis. This study was conducted in following 8 aimags of Mongolia: Bayan-Ulgii, Bayankhongor, Gobi-Altai,Dundgobi, Uvurkhangai, Zavkhan, Khentii, and Orkhon; total population of these aimags is 627762 (m-306482, f-321279). The prevalence of this disease was calculated for 100.000 populations.RESULTS: There have been revealed total 35 patients in 8 aimags. The prevalence for 100.000 population is 5,57 (m-2,61; f-8,40) and has been fluctuated in provinces in range from 1,81 (Uvurkhangai aimag) till 13,28 (Khentii aimag) for100 000 population.The rest 6 provinces (aimags) have prevalence in range from 4,17 (Dundgobi) till 6,38 (Bayan-Ulgii).All patients were distributed by clinical characteristic in next main forms:Cerebro-spinal form in 22 patients (62,8%) among them optico-myelitis in 9 cases (40,9%); Spinal form in 6 patients(17,1%); Cerebral form in 4 cases (11,4%); only optical form in 3 cases (8,6%).Pure spinal, cerebral and optic forms are diagnosed in patients, which have duration of disease no more 6-7 years.By the courses of disease all patients distributed in courses the beginning with acute attack incomplete recovery(remissions) revealed in 18 patients (51,4%), more rapid but steadily progressive course in 5 cases (14,3%), acutesevere attacks course in 5 patients (14,3%).CONCLUSION:1. Multiple sclerosis is spreading in population of Mongolia in last 30 years after 1980.2. The prevalence of this disease in population of 8 provinces (aimags) of Mongolia in 2008 year is 5,57 cases (inmen-2,61; in women-8,40) for 100.000 population. The rates of prevalence of the disease by aimags are oscillated inrates from 1,81(Uvurkhangai) till 13,28 (Khentii) for 100.000 population.3. The women suffered more in 3 time than in man and optic form revealed in 34,2 % cases (in 12 patients). Theage of beginning of the disease was fluctuated in age from 16-19 years old till 60 above years old.4. By level of prevalence of this disease Mongolia now is belonging to countries of the world, which have lowprevalence of this disease (till 10 per 100.000 pop).
RESUMO
BACKGROUND: The study of epidemiology of hereditary neurological diseases in Mongolia began a few years ago. Itcovered a few aimags (provinces) (D.Baasanjav, 2000-2005). Previous studies have shown, that hereditary neurologicaldiseases are not rare in Mongolia and structure and prevalence of these diseases vary by aimags. Mo n g o l i ahas 21 aimags (administrative provinces), each with a population from 45000 till 110440. In some “isolated” populationsspecific neurological hereditary diseases can be marked as “indigenous”. So the epidemiological study of hereditaryneurological diseases in Mongolia is one of the urgent medical shortcoming in Mongolia.MATERIAL AND METHOD: We used descriptive epidemiological method for revealing hereditary neurological diseases infamilies in population of 8 provinces (aimags) of Mongolia, Bayan-Ulgii, Bayankhongor, Govi-Altai, Zavkhan, Dundgobi,Khentii, Orkhon, Uvurkhangai, total of 627,000 population. The population of these aimags fluctuated in the range from47959 (Dundgobi) to 110440 (Uvurkhangai). Diseases were diagnosed by neurologists using clinical and genealogicalmethods.RESULTS: The study revealed 77 patients in 40 families in the studied population with variety of neurological hereditarydiseases. The overall prevalence of hereditary neurological diseases for 100,000 population is 12,26. The prevalencevaries by aimags from 2,08 (Dundgobi) to 32,50 (Gobi-Altai) per 100.000 population. The prevalence and their rangeby nosological structure per 100000 population in aimags are: myotonic dystrophy 5.41 widely varying by aimags: from4.66 in Bayankhongor to 27.09 in Gobi-Altai; Charcot-Marie-Tooth syndrome 1.59 and ranging from 2.08 in Dundgobito 4.66 in Bayankhongor; Duchenne muscular dystrophy -0.79 and ranging from 0.90 in Uvurkhangai to 3.19 in Bayan-Ulgii; the limb girdle muscular dystrophy -0.95 and ranging from 1.81 in Uvurkhangai to 4.66 in Bayan-Ulgii; Strumpellfamilial spastic paraplegia -0.95 for total pop and ranging from 2.71 in Uvurkhangai to 5.41 in Bayankhongor; familialparoxysmal myoplegia -0.79 for total pop. and range from 2.22 in Orkhon to 5.41 in Gobi-Altai; spinocerebellar ataxia -0.47 for total pop. (3.91-in Zavkhan); bulbo-spinal amyotrophy -0.32(only in Bayankhongor); spinal amyotrophy of adults-0.16(only in Uvurkhangai); arthrogryposis with myodystrophy -0.63 (only in Khentii); kyphoscoliosis with myodistrophyand nanism -0.16 (1.06 in Bayan-Ulgii)A comparatively high prevalence of all neurological hereditary diseases per 100.000 pop. was established in Gobi-Altai(32.50), Orkhon-26.56, Bayankhongor-15.16, Bayan-Ulgii -11.70 rates; the low prevalence - in Dundgobi-2.08 and-Zavkhan-3.91.The hereditary neuromuscular diseases among all hereditary neurological diseases taken up 71.9% i.e 55 patients from29 families. The myotonic dystrophy is tops the list of neuromuscular diseases (61.8%)CONCLUSION: Hereditary neurological diseases have a relatively high prevalence among the population of Mongolia,specially the neuromuscular diseases; so the control of these diseases in the country is one of the special priorityproblem of the national health care.
