Background: Bone mineral density (BMD) is a key indicator reflecting bone strength and resistance to fracture. It is influenced by multiple factors, including age, sex, genetic background, body composition, nutrition, and physical activity. During young adulthood, peak bone mass is actively formed; therefore, identifying early variations in this period is essential for predicting future skeletal health risks. Accordingly, assessing BMD and evaluating its relationship with physical characteristics among first-year nursing students provides a scientific rationale for this study. Aim: To examine the relationship between bone mineral density and selected physical parameters among students. Materials and Methods: A total of 297 first-year students aged 17-35 years from the School of Nursing, Mongolian National University of Medical Sciences were included. Bone mineral density was assessed by measuring the speed of sound through the radius using an ultrasound bone densitometry device. Handgrip strength was measured using an electronic dynamometer. Physical parameters including age, sex, height, and body weight were measured using standardized procedures, and statistical analysis was performed. The study was approved by the Research Ethics Committee of MNUMS on November 21, 2025 (No. 26/1) and March 28, 2026 (No. 26/03-B02), with no ethical violations identified. Results: According to T-scores, 37.1% (n=110) of participants had normal bone status and 62.9% (n=187) showed reduced bone density. Based on Z-scores, 52.5% (n=159) were normal, while 45.6% (n=138) had decreased values. T-score values were 1.87±0.69 (<20 years), 1.44±0.55 (20–30 years), and 1.10±0.31 (>30 years), while Z-score values were −0.73±1.38, −0.43±1.23, and −0.02±1.27, respectively. ANOVA analysis revealed statistically significant differences among age groups (p<0.01). A positive correlation was observed between T-score and age, whereas no significant correlations were found with other physical parameters. Z-score showed a positive correlation with handgrip strength. Conclusions 1. A high prevalence of reduced bone mineral density was observed among the students, which may be associated with incomplete attainment of peak bone mass in adolescents and young adults. 2. A significant difference in bone mineral density was found between age groups (p<0.01), indicating that age is an important factor influencing bone mineral density.

Introduction: In 2018, the overall colorectal cancer (CRC) incidence rate was 3.6%, according to the National Cancer Center of Mongolia (NCCM), and the incidence of colorectal cancer has increased slightly in recent years. According to cancer stages, late stage cancer has a 5-year survival rate of 51%, while early stage cancer has a 5-year survival rate of 79%. The overall survival rate of colorectal cancer in Mongolia has not been studied in precisely. In Asia, the 5-year survival rate for colorectal cancer was 60%. Therefore, this study investigated the colorectal cancer survival rate and prognostic factors at NCCM. Methods: A total of 108 patients diagnosed with CRC at NCCM’s General Surgery Department from 2013 to 2015 were used in this retrospective cohort study. The Kaplan-Meier method was used to develop the survival graphs, which were then compared using the Log-rank test. Results: The median survival time was 42 months, with a 95% CI (38.55-45.66). A 5-year period, the overall survival rate for CRC was 61.2%. Survival rates at the I, II, III, and IV stages were 100%, 75%, 65.4%, and 13.5%, respectively. There was a significant difference in CRC survival rates across all stages (p=0.0001). There was a statistically significant difference in determining the relationship between adjuvant chemotherapy and survival rate (p=0.0003). Conclusion The outcome of the surgery is determined by the CRC stage. The postoperative survival rate (61.2%) is directly related to tumor stage, peripheral glandular metastasis, distant metastasis, and chemotherapy effects.

To detect factors influencing infant’s weight growth during the last few years and to do comparing analysis between mother’s and infant’s weight. 3600 birth histories were chosen and used out of all childbirths happened in 2010-2014 in Ulaanbaatar’s First Maternity hospital using random sampling method. Questionnaires consisting of 21 questions were performed within primiparas, mothers giving birth not for the first time and mothers giving birth by cesarean section. Processing of all the workings were done by using Microsoft Word 8 and Microsoft Excel 2007.According to the results of the research there is a tendency to weight growth of the infants. Comparing weights of the first child of the woman (women giving birth repeatedly and women giving birth by cesarean section) with the second one there is an increasing number of infants with heavier weight. And also as per research done within primiparas there is an increasing number of children born weighting more than 4010 grams during last 5 years. To compare heights of the women giving birth, there is a dominating number of women whose heights are between 155-160,9. However, there is a tendency of birth rate to increase in women whose heights are 161cm. According to the research 63% of all women giving birth were 21-30 years old, average age of women is 28,1 years old. We also detected that there is a dominating number of women giving birth for the 2nd time, but also we concluded that there is an increase in a frequency of women giving birth for the 3rd and 4th times as well. Birth frequency\5 years average\: according to the research we have done we are concluding that 46% of all women are giving birth for the 2nd time, 48%- for the 3rd time, 5% of all women are giving birth for the 4th time and 1% of them are having their 5th child. Significants of cesarean section: 338 are repeated cesarean section, 228 are chronic hypoxia, 131are preeclampsia, beech presentation are171 and other. Childbearing time comparing there is an increase in childbearing of 40-41 weeks.. Comparison between first child’s weight and second child’s weight. As per comparison done between a women’s previous child’s weight and a present child’s weights there is a decrease in a number births of children weights of whose are between 3000-3500 g of 8%, and also an increase in number of births of the children weighting 3510-4000 g by 9,2%, of the children weighting 4010-4500 g by 3% and of the children weighting more than 4510 g by 1,4% was seen. Compare between weights of the first child and second child of the women giving birth by cesarean section done between first and second children’s weights we detected that there is an increase in a number of children weighting 3000-3500 g by 10,4%, weighting 3510-4000 g by 10,2%, weighting 4010-4500 by 12,8% and weighting more than 4510 by 2,59%. Women’s first child’s weight comparison are showing there is a dominating number of children born weighting 3000-4000 grams, however, we also see that there is a slightly increase in number of children born weighting more than 4010 grams. As per research we have done between average heights of the women giving birth in a last 5 years we are concluding following: height of 13% of all women who were involved in a research was 149-154 cm, 39%’s height was 155-160,9 cm, 27%- 161- 166,9 cm and 19% of them were taller than 167cm. According to the research we see dominating number of over weighted women. Despite of sampling method not showing good enough picture of weight index increase we can conclude that number of 2r and 3r levels of overweight mothers are not only staying at the same level but also has some tendency to grow. It was observed that the fact of weight gaining, bad eating habits, not doing sports during pregnancy and increasing of women height acceleration and post-term pregnancy are influencing infant’s weight gain which leads to infant’s morbidity and pathology and to complications during pregnancy and childbirth.When women give birth repeatedly with every birth they give there is an increase in a child’s weight. And also between primiparas there is an increased number of children born weighting more than 4010 grams.Between women involved in a research there is a dominating number of women who are 155-160,9 cm tall, however, it is 46% of them whose heights are more than 161 cm. It shows that average height of Mongolian women is increasing.According to weight index not only women with overweight are dominating, but also number of women with 2 and 3r levels of overweight never goes down and slightly increases. From this we may conclude that overweight problems of women are influencing weight of the baby and also contributes to childbirth and pregnancy complications.

Background. The main target of this research paper on “Some issues relating to the family healthcenter, family doctors care and health services” is for the young doctors, and specifically family doctorsand to help their daily work routine.
