Background: Leptopyrum fumarioides (L.) Reichenb a relatively widely distributed annual herbaceous plant belonging to the Ranunculaceae family, grows predominantly in the dry steppe regions of Mongolia. In recent years, the global use of traditional medicine and natural products has increased substantially. In this context, elemental studies of medicinal plants including macroelements, microelements, and heavy metals provide a fundamental scientific basis for evaluating their nutritional value, therapeutic efficacy, safety, and standardization. Therefore, the investigation of the elemental composition of Leptopyrum fumarioides (L.) Reichenb is of significant importance as a foundational study supporting its medicinal application. Aim: To investigate the chemical elements, present in Leptopyrum fumarioides (L.) Reichenb. Objectives: 1. To prepare plant samples and determine the contents of aluminum oxide, silicon dioxide, iron oxides, and calcium oxide in the plant material. 2. To identify and quantify the mineral elements present in the plant material. 3. To investigate the heavy metals in the plant material. Materials and Methods: Leptopyrum fumarioides (L.) Reichenb were collected from Altanbulag soum, Töv Province, Mongolia, during the flowering stage in June 2023. The collected plant materials were air dried in accordance with standard procedures and used for analysis. The quantitative contents of macroelements, microelements, and ultra-trace elements in the plant were determined using high precision X ray fluorescence (XRF) analysis. Result: In the raw plant material of Leptopyrum fumarioides (L.) Reichenb, the silicon dioxide (SiO₂) content was 15.99%, which increased to 33.69% in the extracted residue. Titanium dioxide (TiO₂) was present at 0.16% in the raw material and 0.379% in the plant residue. Aluminum oxide (Al₂O₃) was 3.54% in the raw material and 7.52% in the extracted residue. Iron oxide (Fe₂O₃) was 1.14% in the raw material and 2.51% in the residue. Other oxides, including calcium oxide (CaO), potassium oxide (K₂O), and phosphorus pentoxide (P₂O₅), remained in the extracts. The concentrations of trace elements in the plant were determined as follows: copper (Cu) 40.5 mg/kg, zinc (Zn) 211 mg/kg, chromium (Cr) 8.5 mg/kg, and nickel (Ni) 8 mg/kg. The levels of Zn (211 mg/kg) and Cu (40.5 mg/kg) were found to be relatively higher compared to those reported in other plant species. Conclusion 1. In the raw plant material of Leptopyrum fumarioides (L.) Reichenb, silicon dioxide (SiO₂) content was 15.99%, increasing to 33.69% in the extracted residue. Titanium dioxide (TiO₂) was 0.16% in the raw material and 0.379% in the residue. Aluminum oxide (Al₂O₃) was 3.54% in the raw material and 7.52% in the extracted residue. Iron oxide (Fe₂O₃) was 1.14% in the raw material and 2.51% in the residue. Other oxides, including calcium oxide (CaO), potassium oxide (K₂O), and phosphorus pentoxide (P₂O₅), were retained in the extracts. 2. The trace element analysis revealed the following concentrations: copper (Cu) 40.5 mg/kg, zinc (Zn) 211 mg/kg, chromium (Cr) 8.5 mg/kg, and nickel (Ni) 8 mg/kg. The levels of Zn (211 mg/kg) and Cu (40.5 mg/kg) were higher than those typically found in most plants; however, these concentrations are below the threshold considered toxic to plant physiology. Rubidium (Rb) at 49 mg/kg and zirconium (Zr) at 69 mg/kg were also relatively high compared to other elements. This may be related to the ability of Leptopyrum fumarioides (L.) Reichenb to accumulate certain elements when growing in moderately contaminated soils near cultivated fields. 3. Rare earth elements, such as cerium (Ce) and ytterbium (Yb), were found to be below the general concentration range and can be considered within normal limits. Furthermore, the plant contains numerous trace elements that participate in various enzymatic activities and contribute to the components of the blood coagulation system.

Background: Vulnerable populations at risk of micronutrient deficiencies include children and women, especially pregnant women, lactating mothers, infants and young children. According to WHO guidelines, a population with a micronutrient (vitamin and mineral) deficiency of more than 20% is considered a public health problem.
Although Mongolia has made significant progress in improving the nutritional status of the population, especially children and women, the 2024 VI survey found that micronutrient deficiencies are high among pregnant women.
The MMS (Multi-ingredient Micronutrient Supplement) distributed to pregnant women by soum and household health centers contains all the essential vitamins and minerals for pregnant women, but coverage has remained inadequate for more than 10 years. Goal: To establish the prevalence of micronutrients deficiency in pregnant women Materials and Methods: Totally 2796 pregnant women included in cross-sectional study from urban and rural area. Survey procedures consisted of interview, anthropometric measurements, clinical examinations, and the collection of biological (blood and urine) samples for pregnant women. Micronutrient deficiencies were assessed by tests for hemoglobin, serum, ferritin, soluble transferrin receptor (sTfR), 25-hydroxyvitamin D {25(ОН)D}, spot urine samples for determination of urinary iodine concentration. Statistical processing : The data from the survey questionnaires were entered into a database created in the “EpiData 3.1” software environment. The data created and verified in the EpiData software environment were converted to the “SPSS–25” program, and statistical analysis was also performed using the SPSS-25 program. The results table was prepared using Microsoft Word 2021 and Microsoft Excel 2021 programs. Research ethics: The research methodology was discussed at the meeting of the Medical Ethics Review Committee under the Ministry of Health on 2023.03.27 (23/017), and permission to conduct the study was obtained Result : The prevalence of anemia, as measured by hemoglobin, was 22.3% and the iron deficiency anemia (IDA), as measured by adjusted serum ferritin or soluble transferrin receptor (sTfR) was (39.8%/9.0%). Prevalence of iron deficiency as measured by serum ferritin was also highest in Western 41.9% and lowest in Khangai region 40.2% (P<0.01). The prevalence of vitamin D deficiency among pregnant women was high at 92.5%, and 7.5% of all pregnant women had adequate vitamin D status. The median concentration of 76.4µg/l indicates inadequate iodine status in pregnant women, as the desired range for adequate iodine nutrition in pregnancy 150-249 µg/l. Conclusions 1. 22.3 percent of pregnant women are anemic, and the prevalence of anemia has not decreased from 2017 levels and remains common.
2. The prevalence of iron deficiency (as measured by ferritin levels) was 39.8 μg/L and the soluble transferrin receptor level was 9.0 μg/L, which is higher than previous studies.
3. The prevalence of vitamin D deficiency among pregnant women remains common, with 76.6% having severe or moderate deficiency, and 15.9% having mild deficiency.

Background: Men’s health is a vulnerable associated with higher risk behaviors and is less considered to their health compared to women. According to NSO, of the total population, 49.3 percent were males and 50.7 percent were females in Mongolia. There is a difference in average life expectancy between man and woman, and males live in average eight years (9.2) fewer compared to females. Objective: To determine nutrition status among men aged 15-49 in Mongolia Materials and Methods: The target population was divided into 5 strata based on Mongolia’s socio-economic regions and Ulaanbaatar City. 1950 men aged 15-49 were randomly selected. The confidence interval was set at 95%, with a precision of ±5% or less for all indicators. The sample size was sufficient to obtain representative data on the nutrition status of men at the national level and to calculated using WHO recommendation for adults. Ethics consideration: The survey methodology was discussed at the Scientific committee of National Center for Public Health, on February 6, 2023. Ethics approval was obtained from Medical Ethics Review Committee under the Ministry of Health on March 27, 2023. All participants were participated voluntarily and written informed consent were obtained from participants. Results: The prevalence of overweight and obesity among men was 57.4%, with 17.0% classified as obese. Overweight and obesity rates were highest in men aged 30-39 years (62.2%) and 40 49 years (64.5%) among other age groups. Conclusion In Mongolia, the prevalence of overweight and obesity among men aged 15–49 increased by 9.4 percentage point to reach 57.4%, since 2017 and 17.0% of men aged 15-49 years are now classified as obese, with biggest increase in age group 20-29. The prevalence of obesity was higher among men in the above-average and affluent groups (20.0% and 20.6%) compared to men aged 15-49 living in the average and below-average income groups (10.8% and 13.1%).
Conclusion: In Mongolia, one in two men age between 15-49 years were overweight and obese. The prevalence of overweight and obesity has increase age between 30-49 years compared with other groups.

Introduction: The treatment of antibiotic-resistant bacterial infections has become a pressing problem for humanity worldwide, and antibiotic-resistant bacterial infections are likely to be the leading cause of death by 2050.Due to the mutation of infectious disease-causing bacteria and the emergence of bacterial resistance due to the improper use of antibiotics, the time and cost of infectious disease treatment increases, and in some cases, it leads to an increase in mortality, so it is the focus of the health sector in every country, regardless of the income level of the population. In addition, bacterial resistance has a negative impact on public health, food safety, the environment, and the economy.
As of 2015, Mongolia ranks among the countries with the highest consumption of antibiotics in the world, with 64.41 units of antibiotics prescribed per 1,000 people per day. Bacteria resistant to broad spectrum antibiotics have increased dramatically, and among Gram-positive bacteria, drug-resistant Staphylococcus aureus (MRSA) has become one of the most common and dangerous cause Purpose: Determine the external structure of liposome-encapsulated antibiotics and evaluate their antibacterial activity. Materials and Methods: We conducted this study using an experimental research design. Phospholipids were isolated by intermittent evaporation, antibiotic encapsulation by freeze-thaw method, and antibiotic sensitivity was determined using standard strains by disc diffusion andmicro dilution method. Research ethics: Permission to submit the survey was granted by the Ethics Review Committee of the MNUMS. The survey was granted in accordance with the rules and regulations. Results: In liposome-encapsulated antibiotic sensitivity assays, azithromycin and clarithromycin did not form sacred circles, whereas doxycycline hyclate was sensitive by forming a 16 mm circle. Doxycycline hyclate encapsulated in liposomes formed a 16 mm circle with sensitive results, whereas blank liposomes were inactive. When the rabbits were infected with a standard strain of methicillin-resistant Staphylococcus aureus, the infected area was purulent 24 hours later. A cream containing antibiotics was started at this time. A deep wound was recovered after 12 days after the pus was removed. Nevertheless, after 24 days, the wound on the rabbit’s infected part healed and the hair on the scraped part grew back. Conclusion According to the dilution method, liposome-encapsulated doxycycline hyclate inhibited bacterial growth at 2-fold lower doses than pure doxycycline hyclate. In experimental animal models, liposome-based antibiotic ointment has shown antibacterial activity.

Background: Breastfeeding is the ideal food source for all newborns globally. Proper feeding of infants and young children promotes optimal growth and development, especially in the critical window from birth to 2 years of age. Exclusive breastfeeding for 6 months and continued breastfeeding for the first 2 years of life protects children from infection, provides an ideal source of nutrients, and is economical and safe. Objective: To assess the indicators of infant feeding practices among 0- 23 months old children. Materials and Methods: The NNS V was implemented in 21 aimags (provinces) in 4 economic regions (Central, Eastern, Khangai, Western) and the capital city of Ulaanbaatar. Given the regional differences in lifestyle and nutrition status, target populations were stratified into 5 strata based on economic region and Ulaanbaatar with equal samples drawn from each stratum using a cluster-randomized sampling design [1]. The infant and young child feeding indicators assessed in the NNS V were based on the mother’s or caretaker’s report of breastfeeding and consumption of foods and fluids by the child during the day or night prior to being interviewed. Results: 83.7% of children under 2 years started breastfeeding within 1 hour of birth and though almost all children were ever breastfed (97.9%), a slightly higher percentage of girls were ever breastfed overall and within 1 hour of birth. Children 0-5 months were categorized according to whether they were exclusively breastfed or predominantly breastfed, with the former only allowing vitamins, mineral supplements, and medicine and the latter also including plain water and non-milk liquids. Among children 0-5 months of age, 58.3% were exclusively breastfed and 65.3% were predominantly breastfed, having received other liquids or foods in addition to breast milk. The prevalence of exclusive breastfeeding was lowest in the 4th wealth index quintile (46.5%) and wealthiest quintile (54.0%) households. Conclusions Exclusive breastfeeding and early initiation of breastfeeding practices are unacceptably low in Mongolia; 20% of newborns are not breastfed within 1 hour of birth and more than 40% of infants under 6 months of age are not exclusively breastfed and therefore, not receiving optimum nutritional and immunity benefits from breast milk. Strengthening IYCF counselling in all regions and wealth quintiles to support women to practice optimal breastfeeding, along with counselling and awareness of timely and adequate complementary feeding for children under 2 years of age, should be a top priority for public health and as it is a key strategy to reduce malnutrition in children.

Nutrition is a key factor in the normal functioning of the immune system, and malnutrition is one of the most common causes of immunodeficiency worldwide today. However, the public health policies on immune system and infection lacks the nutritional strategy to ensure the optimal functioning of the immune system Loss of cellular immunity, phagocyte function, blood protein complex, cytokine synthesis, and A-immunoglobulin secretion are generally associated with protein-energy deficiency.
Some vitamins and minerals, such as A, B6, B12, C, D, E, folic acid, zinc, iron, selenium, magnesium, and copper, plays an important role in the immune system function. Deficiency or low levels of micronutrients can negatively affect the immune system and reduce the ability to fight infections.

Background: Iron is an essential mineral needed for physical and cognitive development with iron needs greatest during pregnancy, infancy, childhood, and adolescence. Iron is vital throughout the lifespan as it is a component of haemoglobin, the protein responsible for transporting oxygen from the lungs to body cells for energy production. Iron deficiency results from a depletion of body iron stores due to increased iron needs, inadequate dietary iron intake, reduced iron absorption, or loss of iron from infections caused by malaria, hookworms, and other intestinal parasites. In advanced stages, iron deficiency leads to iron deficiency anaemia, a condition of low red blood cells and reduced oxygen-carrying capacity. Goal: This study aimed to determine body iron stores in Mongolian children aged 6-59 months, and estimate prevalence of iron deficiency among of studied children. Materials and Methods: In this study were used materials that collected during the fifth national nutrition survey conducted in 21 provinces of 4 economic regions and 8 districts of Ulaanbaatar city of Mongolia. The fifth national nutrition survey was household based survey; therefore sampling unit was household with 5 year-old child. We had used demographic information collected by interview methods and laboratory examination results on ferritin, soluble transferrin (sTfR), C reactive protein (CRP) and α1-acid glycoprotein (AFP) in serum samples collected from 6 to 59 months old children, pregnant women and 15–49 year-old men living in child’s households. Serum Ferritin and soluble transferrin (sTfR) were used as a biomarker for iron store and iron deficiency and C reactive protein (CRP) and AFG were used as indicators for acute and chronic infection. The determination of iron status is challenging when concomitant infection and inflammation are present because of confounding effects of the acute-phase response on the interpretation of most iron indicators. Effects of C reactive protein (CRP) and AGP concentrations on estimates of ID according to serum ferritin (SF) and soluble transferrin receptor (sTfR) were considered in the study. Ethical considerations : The survey protocol was discussed at the scientific committee of the Public health institute and approved by director of scientific committee of PHI on June 28, 2016. Ethical approval for conducting the survey, including obtaining biological samples was obtained from the Medical ethics committee under the Ministry of Health of Mongolia on July 7, 2016. Participation in the survey was voluntary, oral and written informed consent was obtained from each participants and adult caregivers of under 5 year-old children. Results: Biomarkers of iron status were adjusted with inflammation indicators and estimated iron deficiency (ID) and total body iron store in 1732 children 6-59 month-olds. The study findings showed that adjusted mean concentration of serum ferritin and soluble transferrin receptor was 33.7 µg/l and 8.8 mg/l in children age of 6-59 months, respectively. The calculated total body iron store by using adjusted SF and soluble transferrin receptor was 2.8 mg/kg among surveyed children. Iron deficiency was estimated by using 2 different biomarkers among selected population group. The prevalence of iron deficiency estimated by using SF was 20.7% in children 6-59 months. Iron deficiency in children defined by using serum soluble transferrin receptor was 27.7%. Conclusions
1. The average serum ferritin and soluble transferrin receptor concentrations was 33.7 µg/l and 8.8 mg/l in children age of 6-59 months, respectively. Total body iron store estimated by using SF and soluble transferrin was 2.8 mg/kg among surveyed children.
2. The prevalence of iron deficiency estimated by using SF and sTfR was 20.7% and 27.7% in children 6-59 months, respectively. According to the WHO recommendation, prevalence of iron deficiency among Mongolian children aged 6-59 months is classified as “prevalent”.
3. Overall proportion of children with low body iron store was 22.4%. The prevalence of iron depletion is relatively common in boys, young children aged 6–23 months, and rural children aged 6-59 months.

Background : Overweight and obesity are conditions of over nutrition resulting from consumption of more calories than the body requires leading to excess body fat accumulation. The prevalence of both overweight and obesity is increasing globally in all age groups in high, middle, and low-income countries and is largely attributed to the “nutrition transition” with a shift from traditional diets to readily available and inexpensive, low-nutrient unhealthy foods high in energy [1].
The move away from traditional to “junk” foods often occurs at the same time as the move of populations away from daily physical activity and increase in sedentary activities such as time spent in front of a phone, computer, or television, furthering increasing the risk of becoming overweight. People who are overweight or obese are at higher risk for serious health problems including hypertension, heart disease, stroke, diabetes, some cancers, and osteoarthritis. The increase in overweight and obesity is accompanied by a dramatic increase in prevalence of above mentioned chronic conditions in the worldwide. While the long-term repercussions of overweight and obesity are severe, they are largely preventable and treatable through healthy diets and healthy lifestyle behaviors [2]. Materials and Methods: The fifth National nutrition survey (NNSV) was implemented in 21 provinces (aimags) in 4 socio-economic regions (Central, Eastern, Khangai, and Western) and the capital city of Ulaanbaatar. Given the regional differences in dietary patterns and nutrition status, target populations were stratified into 5 strata based on 4 regions and Ulaanbaatar with equal samples drawn from each stratum using a cluster-randomized sampling design. In total, 1750 school children data on demographic and dietary information collected by interview methods and anthropometric measurement results were used in this study. Ethical considerations: The survey protocol was discussed at the Scientific Committee of the Public Health Institute (recently named by National Center for Public Health) and granted by order of director of Scientific committee of PHI on 28th June, 2016. Ethical approval for conducting the NNS V was obtained from the Medical Ethics Committee under the Ministry of Health of Mongolia on July 7, 2016. Participation in the survey was voluntary, oral and written informed consent were obtained from adult caregivers of each children. Results: Consumption of unhealthy or junk (high-calorie, low-nutrient) foods in the past week was nearly universal (99.0%) among school children 6-11 years of age. Over half of children (51.4%) consumed junk foods at least once per week and 45.7% consumed junk foods a few times a week. Consumption of sugar-sweetened beverages was high with 80.9% of children consuming these at least once in the past week. Overall consumption of fried foods was lower than consumption of junk foods or sugar-sweetened beverages with 22.7% of children not consuming any fried foods in the past week and only 8.5% of children consuming fried foods a few times per week. Consumption of sweet foods was high with nearly all children having consumed sweet foods in the past week, 45.9% of children 6-11 years having consumed sweet foods a few times per week.
The prevalence of overweight (BMI > +1 SD) was 22.2% and prevalence of obesity (BMI > +2 SD) was 6.4%. Overweight prevalence was higher in boys (26.6%) compared to girls (17.8%) and in urban (23.9%) compared to rural (17.6%) areas with the highest prevalence in Ulaanbaatar (25.6%) compared to other regions. Children 6 years old (26.1%) and 7 years old (25.6%) had a higher prevalence of overweight than older children. Conclusion
1. Consumption of unhealthy foods and drinks is common to 6-11 year olds group, with almost all children (99.2%) consuming any type of unhealthy foods and drinks at least once per week, in particular, 8 out of 10 children were found consuming sugary drinks and/or deep fried food.
2. The consumption of unhealthy foods was not differing by child’s sex, there were revealed significant differences between living area and regions. Proportion of the school children 6-11 years of age was relatively higher in Ulaanbaatar city and urban settings.
3. The prevalence of overweight and obesity in school children aged 6-11years sharply increased from 2010 NNS IV level and reached 22.2% and 6.4%, respectively. Among children with obesity consumption of any unhealthy foods and sugary drinks were 1.4–1.9 times higher than nonobese children, respectively.

Background: In order to study and evaluate the nutrition situation of the Mongolian people. The 2016-2017 NNS V includes 5 different age groups from Mongolian’s four economic development regions and Ulaanbaatar. The NNS V survey quantifies the prevalence of the nutrition conditions that are of greatest concern to the population, particularly young children and pregnant women. Goal: To establish the prevalence of micronutrients deficiency and estimate micronutrient intake in pregnant women Materials and Methods: Totally 2220 pregnant women included in cross-sectional study from urban and rural area. Survey procedures consisted of interview, anthropometric measurements, clinical examinations, and the collection of biological (blood and urine) samples for pregnant women. Micronutrient deficiencies were assessed by tests for hemoglobin, serum, ferritin, soluble transferrin receptor (sTfR), retinol-binding protein (RBP), 25-hydroxyvitamin D {25(ОН)D}, spot urine samples for determination of urinary iodine concentration. Result: The prevalence of anemia, as measured by hemoglobin, was 21.4% and the iron deficiency anemia (IDA) was 10.5%, as measured by adjusted serum ferritin or soluble transferrin receptor (sTfR) was 29.6%.
Prevalence of iron deficiency as measured by serum ferritin was also highest in Western 35.1% and lowest in Eastern region 21.5% (P<0.01). The prevalence of vitamin D in pregnant women was high with 75.4% and 4.4% of all pregnant women had sufficient vitamin D status. An additional 20.2% of pregnant women having insufficient levels. The median concentration of 120.5µg/l indicates inadequate iodine status in pregnant women, as the desired range for adequate iodine nutrition in pregnancy 150-249 µg/l. Conclusion
1. One in every 5 pregnant women (21.4%) is anemic.
2. Vitamin D intake among pregnant women (7.3%) is very low, with 75.4% having vitamin D deficiency and vitamin D insufficiency –by 20.2%.
3. Median urinary iodine concentration of pregnant women is 120.2mg/l, considerably lower than WHO recommended reference range, indicating pregnant women are at risk of iodine deficiency.
4. Despite visible growth in vitamin and mineral supplements intake by pregnant women, compared to 2010, the infrequency of intake and failure to consume recommended number of supplements as instructed in the relevant guides persist.

Hemangiomas are common benign vascular tumors which about 70% to 80% of the lesions are found in the head and neck region. This study was conducted on 36 children with hemangioma who were referred to Orofacial Surgery Cabinet of Dental School of Health Sciences University of Mongolia and Orofacial Surgery Cabinet of National Center for Maternal and Child Health of Mongolia between 2013 and 2015.Of the 36 children referred for assessment, 72% were female, 55% were infants of 4 to 9 months old, and 83% of them were citizens. 58% of patients underwent cryotherapy,and 57% of patients underwent cryotherapy had 2 therapy sessions. 25% of patients receiver sclerotic therapy, and 67% of them had 2 therapy sessions. According to the locations of hemangiomas 30% of them were localized in infraorbital area. 72% of the participants are women and 55% are children age of 4-9 month which 83% of all participants were living in city. 58% of children with hemangioma are treated with cryotherapy which 57%of treatment finished by second visit. And 25% were treated by dehydration treatment which 67% were finished by second visit.
