Abstract According to the World Health Organization (WHO) report in 2023, arterial hypertension (HTN) remains one of the leading causes of global morbidity, with an estimated 1.3 billion individuals diagnosed worldwide. Among them, 42% were receiving antihypertensive treatment, and only 21% achieved adequate blood pressure control. In the United States, 47.7% of the adult population is diagnosed with hypertension, with prevalence increasing significantly with age [1,2]. Multiple factors such as lifestyle, body mass index (BMI), age, sex, genetics, and physical inactivity are well-documented contributors to hypertension, as evidenced by both international and local studies. Specifically, individuals classified as obese demonstrate a higher prevalence of hypertension based on BMI categorization.
However, in Mongolia, limited studies have investigated the contributing factors and treatment outcomes of hypertension, highlighting the necessity of this study.
A retrospective study was conducted by reviewing the medical records of 50 inpatients diagnosed with arterial hypertension (ICD-10 codes I10–I15) who were admitted to Sindura-Med Hospital between 2023 and 2024.
1. In patients with stage 1 and 2 arterial hypertensions, age, mean systolic and diastolic blood plessure, heart rate and elevated cholesterol levels were found to be correlated with body mass index (BMI). Among smokers, the risk of developing cardiovascular diseases is projected to increase over the next 10 years
2. In the hypertensive group aged 60 years and older, echocardiographic examination revealed structural and functional abnormalities.
3. In the pharmacological management of arterial hypertension, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, combination preparations, and diuretics were the most commonly prescribed medications.

Introduction: University students encounter multiple academic, psychosocial, and environmental stressors during their transition to higher education. Nursing students may be particularly vulnerable because of concurrent academic and clinical demands. Objective: To identify the relationships among perceived stress, social support, and psychological anxiety among nursing students. Methods: A cross-sectional quantitative study was conducted among first- to fourth-year nursing students at the International University of Ulaanbaatar. After excluding 16 incomplete questionnaires, 119 valid responses were analyzed using descriptive statistics, reliability testing, and correlation analysis in SPSS version 26.
Participants had a mean age of 22.39±5.60 years, and 86.6% were female. The mean item scores were 3.15±0.40 for perceived stress, 4.11±0.78 for social support, and 2.35±0.39 for total anxiety. Perceived stress was positively correlated with total anxiety (r=.310, p=.001), personal anxiety (r=.307, p=.001), and situational anxiety (r=.261, p=.004), and negatively correlated with age (r=-.213, p=.020). Social support was not significantly correlated with perceived stress (r=.015, p=.872) but was negatively correlated with total anxiety (r=-.253, p=.005) and personal anxiety (r=-.334, p<.001). Conclusion Students’ perceived stress was associated with anxiety. Higher social support was related to lower anxiety, although a direct relationship between social support and perceived stress was not observed in this sample.

Introduction: Antibiotics are commonly prescribed in paediatrics.¹ Children were 1.3 times more likely to be treated with antibiotics compared to adults.² Especially, antibiotic prescription is higher in children aged under 5 years.³ Purpose: To identify the most widely used antibiotics in the age group of 0-5. Objectives of the study:
1. To identify the most widely used antibiotics and classify them by pharmacological group
2. To analyze the pharmaceutical dosage forms of commonly prescribed antibiotics for infants and toddlers Methods: In our study, we selected 20 pharmacies from 6 districts (Bayanzurkh, Bayangol, Khan-Uul, Songinokhairkhan, Chingeltei, and Sukhbaatar) of Ulaanbaatar city using a single random sampling method. A total of 496 antibiotic prescriptions written for children aged 0-5 years in 20 pharmacies were analyzed. Antibiotic prescription forms for children aged 0-5 years registered in the pharmacies in November, December 2023, and January 2024 were collected. The results were processed using “SPSS 29.0.2” program. Result: Among a total of 496 antibiotic prescriptions written for children, 341 were written in solid dosage form and 155 were in liquid dosage form (suspension). Amoxicillin 250 mg and Amoxiclav 312.5 mg were mostly used from Penicillin group for the treatment of infants and toddlers. Clarithromycin 125mg/5ml from Macrolide group had an important role in treatment. Cefixime 400 mg from the Cephalosporin group was used in some cases such as diarrhea and vomit. Conclusions
1. Amoxicillin, Amoxiclav, Clarithromycin (Penicillin, Macrolide) antibiotics are the most widely used in the treatment of infants and toddlers.
2. It has concluded that antibiotic prescriptions for infants and toddlers mainly include solid and suspension antibiotics.
