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: For the past few years, the number of non-communicable diseases and accident-related injuries have been rising which has been heavily influenced by the technology advancement and urbanization. According to the World Health Organization, osteoporosis comes in fourth after cardiovascular diseases, cancer, diabetes in terms of spread. In 2018 at Saran-Elit Clinic in Darkhan-Uul province, 43 patients were selected to participate in a clinical study that was conducted by examining bone essence’s waste and/or fingernails. Methods: Participants’ radial’s dentistry of bones was examined thoroughly by Sunlight, Miniomni, (Beammed, Israel), an equipment with SOS and T-score. Results and conclusions The average age of the participants was 38.6918.08. The dentistry of bones of the participants were 3704 m/s-4399 m/s which showed that most of the participants were already experiencing osteoporosis. According to the statistics, when fingernails were studied by the traditional method, osteoporosis in the skull, neck and shoulder blades bones took up to 43%, higher risk of developing osteoporosis in the upper extremity to the right hand bones, and equal amount of risks in both lower extremities (p<0.05). When bones dendistry is determined by the equipment, 25.8% showed healthy, 30.9% was in the range of early osteoporosis and the remaining 43.3% was in the range of osteoporosis. As a conclusion, equipment testing is expensive and time consuming vs. the traditional method is free of charge, time efficient and easier to analyze the signs and results etc.
