Goal: To determine schoolchildren’s growth and nutrition situationMaterials and MethodsThe descriptive and cross sectional study was carried out in 4 districts of Ulaanbaatar city (750 schoolchildren from each district) and 2 aimags (889 schoolchildren from Uvurkhangai and 925 from Dornod) of Mongolia. The study was conducted in two steps, Step 1 or beginning of school year covered totally 4760 schoolchildren and in end of school year totally 4108 schoolchildren. Data for the survey was collected by using questionnaire and clinical examintions and antropometric measurements. Weight of schoolchildren was used UNISCALE electrical scales with precision to 100g and height was used standard measurement with precision to 1mm. Schoolchildren’s growth was assessed by method “Sigma” and compared to the survey “Growth means of schoolchildren up to 16 years of Mongolia” (PHI, 2006). The nutritional status of schoolchildren were taken in accordance with the Z score calculated with relation to WHO average population anthropometric reference (WHO, 1995). Also determined current nutrition situation of surveyed schoolchildren by using 24 hours recall method and assessed. Nutrition assessment was used the standard indicators of Technical Committee, WHO [3, 7, 8].ResultsA total of 4760 (46.6% boys and 53.4% girls) school children were present beginning of the school year and 4108 (46.0% boys and 54% girls) of their were end of school year during the visit. Almost 60 of the total school children were from districts of UB beginning and end of school year. Beginning of the school year, 5.1 percent of total surveyed schoolchildren were assessed underweight and 14.1 percent is stunting, 1.7 percent is wasting and end of school year it was 4.7 percent underweight, 13.9 percent stunting and 1.2 percent wasting.71.7 percent of total respondents have breakfast sometimes, 83.2 of them have a lunch only one time per day, and 38.3 percent of total daily energy takes from dinner and have not any difference between age groups. Consumption of food products such as green vegetables, beef liver which are rich with vitamin A is inadequate. Example; among 7-10 years old 184.9 mcg, 11-14 years 247.2 mcg, above 15 years old was 241.6 mcg. Amount minerals such as calcium and phosphorium per day was among 7-10 years old 398.2mg and 756.1мг, 11-14 насанд кальци 277.8-301.5мг, фосфор 688.6-899.5мг, above 15 years old was calcium 366.4-378.3mg, phosphorium 875.3-978.8mg. Dairy consumption was analyzed by urban and rural areas among schoolchildren and it was among urban schoolchildren is more by 16.6-21.4 percent from rural areas.Conclusion:1. The progress made improving gradually the nutritional status of schoolchildren from previous study. The prevalence of underweight, stunting and wasting is “low” level among schoolchildren by WHO. There is statistically significant lower nutritional status among schoolchildren in rural area than in urban.2. Micronutrient deficiency is main reason of undernutrition among schoolchildren. In other words, the vitamins (C, A, D), and minerals (Ca, Fe) which are essential for schoolchildren growth and fiber is insufficient in their food. The consumption of diary is inadequate among schoolchildren of rural area compared to urban.3. Consumption of fruits and vegetables and diary products is inadeguate among total surveyed schoolchildren especially in rural area.

BackgroundAn estimated 522 066 students are studying in secondary school of Mongolia and it was 19% of total population. Population life expectancy and health status is directly related to adolescents’ health, as many chronic disease conditions are affiliated with adolescence. Many premature deaths among adults result from behavior initiated during adolescence. According to the NRC survey, one in thirteen schoolchildren (7.3%) was underweight, 16.3% was stunting, and 13.8% were iodine deficiency. It has taken 52.8% of total daily energy among 11-14 years schoolchildren and 50.5% were between 15 and 17 ages. In addition, research in Mongolia in 2005 indicate serious problems in healthy eating behavior; 8% of adolescents consumed milk products on daily basis, 71.7% had breakfast only sometimes, and 83.2% had a meal one time per day. Micronutrient deficiency such as anemia, A, D vitamins among them is cause of low consumption of vegetable and fruits. There is a need to study schoolchildren’s dietary recall.ObjectiveTo study and evaluate schoolchildren’s nutritional statusMaterials and MethodsThe descriptive and cross sectional study was carried out in 4 districts of Ulaanbaatar city (750 schoolchildren from each district) and 2 aimags (889 schoolchildren from Uvurkhangai and 925 from Dornod) of Mongolia. Also determined current nutrition situation of surveyed schoolchildren by using 24 hours recall method and assessed.ResultA total of 4760 (46.6% boys and 53.4% girls) school children surveyed and 46.6% were boys and 53.4% were girls. 71.7 percent of total respondents have breakfast sometimes, 83.2 of them have a lunch only one time per day, and 38.3 percent of total daily energy takes from dinner and have not any difference between age groups. Adolescent aged 7-10 years takes 92.7 percent of total calorie, 90.1 percent of protein, 93.9 percent of carbohydrate and 92.3 percent of fat compared to RDI of Mongolia and thus animale fat is the 1.6 times more than the norm. Consumption of vitamins and minerials such as vitamin A, and iron8 calcium were insufficient among schoolchildren. Specially, it was lower among male student than female. For instance vitamin C intake was 48.0- 58.6 percent among female students aged above 11 years and it was 47.3- 51.8 percent for male students. About 30 percent of total calcium is consumed per day among overal respondents. Conclusions:1. Daily intake of basic nutrients and energy is lower by 10-30 percent than RDI of Mongolia among schoolchildren.2. High consumption of in diet among male adolescents of age 15 years and above causes disbalance of adequate ratio of main nutrients as protein8 fat and carbohydrates.3. There is not enough suffecient consumption of vitamins and minerials specially calcium.

IntroductionThe imported food products are more than 60 percent of total food consumption of Mongolia. Thelead residue in food products causes chronic and acute poisoning to the human health when exceedsmaximum residues limits, and human exposure and significant public health problems in many partsof the world.GoalTo assess lead residues and health risk of some commonly consumed imported food productsamong Mongolian population.Objectives:1. To determine consumption of some imported food products of Mongolian population;2. To investigate lead residue in some commonly consumed imported food products;3. To assess potential health risk related lead residue.Materials and MethodsThe research used analytic study of cross-sectional study design. Randomly selected 1290 people’simports food consumption was analyzed by questionnaire and body weight measurements. Tooksamples from 145 import products, identified lead residue with Academy of Sciences Soil ResearchLaboratory`s, ASS (USA, 2002) equipment.Results60.7% of imported food samples were lead residues exceeded to Maximum Residues Limits, suchus mean lead residues in meat product were 1.55 mg/kg, in milk product 1.22 mg/kg, in cerealproducts 1.15 mg/kg, in vegetables 1.57 mg/kg, in fruit and fruit juice 1.03 mg/kg, in alcohols drink1.31 mg/kg, and in tea 1.93 mg/kg (p=0.001). Estimated Provisional Tolerable Weekly Intake (PTWI)of lead exposure for survey responses was 0.079mg/kg body weight.Conclusions:1. 60.7% of imported food samples were lead residues exceeded to Maximum Residues Limits,such us mean lead residues in meat product, milk products, fruits and vegetables.2. Imported vegetables (54.0%), cereal 8.4% products (15.5%), fruit and fruit juice (11.8%), andmilk products (8.4%) is main contributing to lead residues in imported food.3. Estimated Provisional Tolerable Weekly Intake (PTWI) of lead exposure for survey responseswas 0.079mg/kg body weight, which is 3.2 times higher than toxicological guidance (PTWI 0.025mg/kg per 1 kg human body weight) and the high health risk level.

BACKGROUND: According to the United Nations, drug reports 2016, 250 million people aged 15 to 64 an estimated 29 million of them have used drugs and narcotics. The United nations states that the drug and narcotic manufacturing have increased by three times in east 15 years. Mongolia is located between Russia and China that are the most drug used countries in the world and it can increase the risk of drug usage in Mongolia. OBJECTIVE: Study to knowledge and attitude about drugs and narcotics among the high school, college and universities students in Ulaanbaatar. METHODS: The research was conducted among the school, college and universities students and the analytic research method was used in our research. 176 middle and high school students, 215 university students and 70 college students from morning classes were participated in the survey. The survey research was used method of collecting information and materials about the drug usage and narcotics. SPSS 17 was used for statistical analysis. RESULTS: The highest point was 16 (n=1) and lowest point was 0 (n=16) and the knowledge of drugs among the students was 8.14. Results releated that 7.8% (n=36) of students have enough information about the drugs and narcotics, 62.9% (n=261) of students did not have enough information and 29.3% (n=135) of them have informed moderately. CONCLUSIONS: Exploring the knowledge about drugs and narcotics among the students, 7.8% of them have enough information, 62.9% of them did not have enough information and 29.3% of them have informed moderately
