Item type:Publication, Prevalence of major noncommunicable diseases and risk factors by region: Findings from the National Screening(Mongolian National University of Medical Sciences, 2025-12-26); ; ; Objective: Noncommunicable diseases (NCDs) are the leading causes of morbidity and mortality worldwide, accounting for the majority of premature deaths. Mongolia faces a particularly high burden of cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes, contributing to over 80% of total deaths. This study aimed to examine the prevalence of major NCDs and associated risk factors among the adult population of Mongolia by region. Methods: This study utilized large-scale screening data from the mass screening program of adults aged over 18 years. Results: A total of 447,409 adults were included in the analyses. High prevalence of NCD risk factors was observed, including smoking (16.6-19.1%), alcohol use (5.9-11.7%), physical inactivity (76%–80%), and insufficient fruit and vegetable intake (63%–79%). Regional comparison showed that the Northern region had the highest rates of smoking (19.2%), alcohol use (13.4%), and obesity (24.7%) (p<0.001). In contrast, Ulaanbaatar reported notably higher rates of chronic gastritis and peptic ulcer disease (82.2%–18.5%) compared to other rural regions (p<0.001). Conclusion: NCD risk factors are common across all regions of Mongolia, with clear differences between them. Notably, the urban population has higher rates of stomach and esophageal inflammation and ulcers, likely linked to lifestyle factors and obesity. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Molecular epidemiology of SARS-CoV-2 in Mongolia, first experience with nanopore sequencing in lower- and middle-income countries setting(Wiley, 2023-12); ; ; ; Burged, NatsagdorjBACKGROUND: Coronavirus disease (COVID-19) has had a significant impact globally, and extensive genomic research has been conducted on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage patterns and its variants. Mongolia's effective response resulted in low prevalence until vaccinations became available. However, due to the lack of systematically collected data and absence of whole genome sequencing capabilities, we conducted a two-stepped, nationally representative molecular epidemiologic study of SARS-CoV-2 in Mongolia for 2020 and 2021. METHODS: We used retrospective analysis of stored biological samples from November 2020 to October 2021 and a variant-specific real-time reverse transcription polymerase chain reaction (RT-PCR) test to detect SARS-CoV-2 variants, followed by whole genome sequencing by Nanopore technology. Samples were retrieved from different sites and stored at -70°C deep freezer, and tests were performed on samples with cycle threshold <30. RESULTS: Out of 4879 nucleic acid tests, 799 whole genome sequencing had been carried out. Among the stored samples of earlier local transmission, we found the 20B (B.1.1.46) variant predominated in the earlier local transmission period. A slower introduction and circulation of alpha and delta variants were observed compared to global dynamics in 2020 and 2021. Beta or Gamma variants were not detected between November 2020 and September 2021 in Mongolia. CONCLUSIONS: SARS-CoV-2 variants of concerns including alpha and delta were delayed in circulation potentially due to public health stringencies in Mongolia. We are sharing our initial experience with whole genome sequencing of SARS-CoV-2 from Mongolia, where sequencing data is sparse.Scopus© Citations 1
