Osteoporosis is a disease in which the density of bone is decreased with consequent increase in bone fragility and susceptibility to fracture risk. Vitamin D deficiency may cause secondary hyperparathyroidism and low bone mineral density. Our study was aimed to assess relation between vitamin D status and parathyroid hormone and bone density in adults. Relatively healthy 369 participants aged between 20-60 were randomly selected from Ulaanbaatar city. Specially designed questionnaire was used in the survey. Bone mass density was diagnosed according to the WHO criteria by the T-score. Respondents serum calcium and phosphorus levels were described by the fully automated analyzer (Cobas Integra 2800, Germany). Serum parathyroid hormone and 25-hydroxivitamin D levels were described by using ELISA kit (Eucardio Laboratory, Inc. USA) at the Molecular biology laboratory of MNUMS.The statistical result was analyzed by SPSS 21 program. The subjects mean age was 47.61±12.92, with a range of 20-83. The mean T-score was -0.60±2.17. Our study showed that negative correlation between bone mass density values at parathyroid hormone (r=-0.58, p<0.05), 25-hydroxyvitamin D (r=-0.48, p<0.05) and serum calcium (r=-0.21, p<0.05). Our study showed increased serum parathyroid hormone led the releasing calcium from bone and decreasing bone mass density.

To measure hardness of bone density, and study its relationship with serum calcium, phosphorus, Calcitonin levels and urine calcium level.Pre-designed questionnaire is used to reveal any risk factors associated with osteoporosis and also BMI is evaluated based on measurements of weight, height, bust and waist circumference. Study participants were measured their bone mass density of wrist and shin by ultrasound ( Sunlight MiniOmni, Beammed, USA). Serum calcium and phosphorus levels were analyzed by automatedbiochemical analyzer, Integra 800, according to the adhered protocol to the machine. New, clean urine containers were distributed to participant a day before urine test day and middle part of urine is collected into the container. The urine calcium level was analyzed by automated biochemical analyzer, Cobas Integra 800, according to the machine protocol. Calcitonin level was analyzed by ELISA kit by Eu cardio company of United States.Total of 80 people ages 26 to 87 from Ulaanbaatar were participated for this study. 29 (36.3%) ofthem were males whereas, 51 (63.8%) of them were females. Serum calcium average level was2.0+-0.2mmol/L, serum phosphorus average level was 0.8+-0.1mmol/L while urine calcium level was 3.9+-2.5mmol/L. According to our result, bone mass density was related to age (r=-0.495), serum calcium level has statistically important relationship (p<0.05) with bone mass density (r=-0.326), age(r=0.277), serum phosphorus (r=0.351), and urine calcium level (r=-0.316). Measurement above did not have statistically important relationship with Calcitonin level.Osteoclast might be dominating in osteoporosis since bone mass density is decreasing while serum calcium level is increasing along with aging.

IntroductionOsteoporosis is becoming an increasingly important economic and public health problem as ourpopulation ages. Different results are reported about osteoporosis rate among various geographicalzones and ethnic groups even in same country. These differences cannot be attributed to hormonalstate or to the dietary intake of calcium, but do accord in general with the living standards of the differentcountries and the degree of physical activity undertaken by the different populations and sexes.GoalTo determine the osteoporosis rate among Mongolian adults and evaluate the geographical distributionsof osteoporosis rateMaterials and MethodsOur study group was 1990 adults who are over 18 years and participated from Uvs, Arkhangai, Dundgovi,Sukhbaatar province and Ulaanbaatar. We have evaluated serum PTH, 25-hydroxyvitamin D level andbone mineral density via bone sonometer (Sunlight Mini-Omni, Beammed, USA). Lifestyle risk factorswere evaluated through a specific questionnaire.ResultsThe osteoporosis rate is 25.5% (n=507) among Mongolian adults and 2 times higher in women thanmen in all age group. SOS was inversely correlated with age in both sexes (men: r=-0.286, p<0.01,women: r=-0.513, p<0.01). Osteoporosis rate was lowest in Ulaanbaatar but highest in Arkhangai(male osteoporosis) and Dundgovi province (female osteoporosis). Of 25-hydroxyvitamin D values 29%were below 20ng/ml (deficient), 39.8% ranged from 20-29.9ng/ml (insufficient) and 31.2% were above30ng/ml (sufficient). In addition, 25-hydroxivitamin D concentrations were not related to bone density.Serum 25-hydroxivitamin D level was highest in Dundgovi province in both sexes. Mean PTH level was26.0±17.7pg/ml and inversely correlated with T-score (r=-0.248, p<0.01) in men.ConclusionOsteoporosis rate among Mongolian adult is lowest in Ulaanbaatar comparing to other rural areas. Andserum 25-hydroxivitamin D deficiency is 68.8% in Mongolian adults.

BACKGROUND. According to the World Health Organization (WHO), 10-15% of couples of reproductive age have infertility. According to researcher D. Sukhe (1999), hormonal infertility in the reproductive age of women was 33.6%, which was a large part of the cause of infertility. In recent years, the number of cases of endocrine disorders, including malignancy and sexually transmitted infections, have been increasing year by year. According to WHO reports, thyroid disorders have a prevalence of 49.3% among active reproductive age (30-50) group. According to the report of the Health Development Center in 2016, since the thyroid disorders are the second most common disease in endocrine gland disease, our study has found that the infertility in reproductive age of women can be substantial due to the loss of thyroid gland. OBJECTIVE. To study the relationship between the thyroid gland antibodies and female infertility. MATERIAL AND METHODS. The study was carried out in 20-45 year old couples and was modeled as an analytical study model. The questionnaire was used for the couple’s interviews, antroplogical measurements, and serum was analysed. On the serum, anti-TPO and аnti-TG carbohydrates were identified by the Cobas e-411 analyzer under the manufacturer’s accompanying protocol. RESULTS. Prevalence of TAI, in 6.7% positive anti-Tg were found, and 14.3% had positive TPO. In 3.7% of cases, both types of autoantibodies were present. We analysed binary logistic regression for anti-TPO and anti-TG autoantibody in the positive and negative group in relation to the past obstetrics history. A=Accoding to the analysis, evidence of positive anti-TPO and anti-Tg increased the risk of miscarriage by 2.2 times (OR = 2.2, p <0.01). CONCLUSION: Women with infertility in our study have high percentage of subclinical hypothyroidism and have higher rate of thyroid autobodies in serum which could be a problem for women with infertility and pregnancy complications due to the loss of thyroid gland. Thus, there is a need to develop intervention guidelines for recovery and treatment of these types of infertility.

BACKGROUND: According to International osteoporosis foundation report, osteoporosis is a multifactorial condition associated with an increased risk of fracture and is caused by social, behavioral and physiological factors. Overall incidence is increasing in every country due to people’s life style changes, diet and increased life expectancy. OBJECTIVES: To evaluate the some hormonal effects in bone mineral density among Mongolian population. METHODS: Bone density was measured in the distal one third of radius using the Sunlight Omnisense (Sunlight Medical, Rehovot, Israel) and classified into 3 groups according to WHO osteoporosis criteria. Normal participants were selected into control group and osteoporotic participants were selected into control group. We have evaluated PTH, calcitonin, 25-hydroxy vitamin D in case-control group. RESULT: The prevalence of osteoporosis was 25.7% and 25.3% of participants were osteopenic. It was clear that PTH elevated group (>30.3pg/ml) had more risk of osteoporosis. CONCLUSION: The prevalence of osteoporosis was 25.7% and 25.3% of participants were osteopenic. PTH elevation is risk factor in men.

BACKGROUND. According to the International osteoporosis foundation, the incidence of osteoporose in men is increasing rapidly. Some investigations mention the serum testosterone hormone decreases by aging and may cause of osteoporose. Our study was aimed to evaluate relation between serum total testosterone and bone mineral density in men. MATEREALS AND METHOD. Relatively healthy 624 men aged between 18-87 were randomly selected from Mongolian 4 provinces and Ulaanbaatar city. Specially designed questionnaire was used in the survey. And some of measurement, Weight, height and BMI, was measured. Bone mass density was diagnosed according to the WHO criteria by the T-score. Serum total testosterone level were described by using ELISA kit (Eucardio Laboratory, Inc. USA) at the laboratory of MHI.The statistical result was analyzed by SPSS 22 program. RESULTS. The subjects mean age was 48.56±16.63, with a range of 18-87. The mean SOS was -4055.23±228.89. And the osteoporse was 14.6% (n=91) in all of participants. 152 participants were randomly selected from all participants and classified 2 groups(case and control) according to WHO osteoporosis criteria and evaluated relation between serum total testosterone and bone mineral density. The mean of serum total testosterone level was significantly low (8.80±2.67) in case group than (9.33±2.44) control group (p<0.05). Our study showed that positive correlation between bone mass density values at testosterone hormone (r=0.17 p<0.034). CONCLUSION. Our study showed decreased serum total testosterone hormone affected to decrease of bone mineral density.

Purpose: Researchers suggest that the prevalence of infertility varies between developing and developed countries, with differences in infertility care, socioeconomic status, lifestyle, and reproductive disorders such as pelvic inflammatory disease and sexually transmitted infections being the main risk factors. The research project aims is to define risk factors for female fertility in the Mongolian population. Methods: This study was conducted between 2016-2018 using a cross-sectional survey of analytical research. Participants were randomly selected from Ulaanbaatar and the Central, Western, Eastern, and Khangai provinces according to Mongolia’s regional geographic model. The contents of a questionnaire were comprised of 5 units with 95 questions including socio-economic, geographical, lifestyle, health education, reproductive health indicators, sexual behavior. General physical characteristics were measured according to the standard. Results: The prevalence of the female fertility rate in the Mongolian population is 7.4%. Female participants were classified into 2 groups, namely infertile and fertile, and we developed a case-control study. Among the socio-economic factors influencing infertility, primary education aOR: 1.6 (95% CI 0.98-2.66), monthly household income lower than the average aOR: 1.1 (95% CI 0.77- 1.66), living in rural areas OR: 2.3 ( 95% CI 1.46-3.68) were crucial risk factors. As for reproductive and general health indicators, STIs aOR: 1.8 (95% CI 0.98-3.50), especially gonorrhea OR: 2.8 (95% CI 1.14-6.91), and thyroid disorders OR: 1.7 (95% CI 1.03). -2.97), grade 3 obesity OR: 3.8 (95% CI 1.05-13.95) are estimated risk factors for infertility. Conclusions Of all potential socio-economic factors, residence status, education and financial situation are significant for female infertility meanwhile reproductive health indicators include sexually transmitted infections, thyroid disease, and obesity.
