Background: Background: In recent years, ensuring a safe and healthy working environment for mining employees, improving working conditions, protecting and promoting health, and paying attention to other factors affecting health have become essential requirements. While infectious diseases, noncommunicable (chronic) diseases, nutritional disorders, occupational injuries, and mental health conditions are the main indicators for assessing the health impact on mining workers, there is still a lack of research on noncommunicable diseases among mining sector employees in Mongolia. This gap served as the basis for the present study. Aim: To study the risk factors of noncommunicable diseases among employees of Erdenet Mining Corporation Materials and Methods: A total of 303 employees from 15 divisions of Erdenet Mining Corporation participated in the study. Participants belonging to high-risk groups for noncommunicable diseases were selected using a purposive sampling method. The survey questionnaire was developed based on the WHO STEP wise approach to Surveillance (STEPS) of noncommunicable disease risk factors. Results: Of all participants, 70% were male and 30% were female, with an average age of 46 years. The average total duration of employment was 23 years, of which male employees had worked an average of 19.3 years and female employees 17.3 years at Erdenet Mining Corporation. Among participants, 48.5% had never smoked, while 38.3% were current smokers. When analyzing alcohol consumption by job position, it was found that 85.7% of managers and 66.7% of administrative and decoration workers had high levels of alcohol consumption. Regarding physical activity, 23% of male and 15.2% of female employees reported engaging in active exercise more than three days per week, indicating that male employees were more physically active than females. In terms of dietary habits, 28.3% of males and 17.6% of females did not control their salt intake. As for eating patterns, 53.6% of employees regularly had breakfast, 77.3% regularly had lunch, and 76.6% regularly had dinner at a fixed time. Conclusions 1. Among the employees surveyed, 48.5% had never smoked, while 38.3% were current smokers. Daily smoking was most prevalent among employees aged 35–54 years (74.2%), with the 25–34 age group also showing a relatively high rate of smoking. Regarding alcohol consumption, 38.2% of male employees reported drinking vodka or similar alcoholic beverages. Alcohol consumption was significantly higher among males compared to females, indicating that it is a major risk factor for noncommunicable diseases (p=0.003). 2. In terms of dietary patterns, 53.6% of employees reported regularly having breakfast, 77.3% regularly had lunch, and 76.6% regularly had dinner. Eating habits varied by gender. Concerning physical activity, 23% of male employees and 15.2% of female employees engaged in regular exercise, indicating that male employees were more physically active than females. The study found that lifestyle and behavioral factors such as smoking, alcohol consumption, insufficient physical activity, and poor dietary habits contribute to an increased risk of noncommunicable diseases among employees.

Background: Researchers have identified that occupational exposures related to mining operations-such as dust, noise, and vibration—can increase the risk of developing occupational diseases, including pneumoconiosis, hearing loss, and spinal injuries, as well as noncommunicable conditions such as hypertension and cardiovascular diseases. Work-related stress, living away from family, reliance on portable food services, and shift work systems also contribute to weight gain and negatively affect endocrine function. Aim: To investigate the prevalence of metabolic syndrome and noncommunicable diseases among employees of Erdenet Mining Corporation Materials and methods: A total of 303 employees from 15 divisions of Erdenet Mining Corporation participated in the study. Participants included employees with 10–20 years or more of service; 15% were female, and 75% were technical workers. Employees belonging to high-risk groups for noncommunicable diseases were selected using a purposive sampling method. Results: When analyzing body mass index (BMI) by occupation, overweight or obesity was found among 79.2% of service workers, 65% of electricians, 100% of fuel distributors, 77.8% of decorators, 75.5% of mechanics, 94.7% of specialists, 86.4% of professional workers, 75.7% of operators and engineers, and 88.9% of administrative staff. Central obesity was also analyzed by job position, revealing that 79.2% of service workers, 60% of laboratory staff, 35% of electricians, 64.9% of operators and engineers, and 66.7% of administrative employees had central obesity. Among all participants, 20.7% had a previous history of cardiovascular disease, of whom 71.4% were male and 28.6% were female. The mean blood glucose level among participants was 6.0 mmol/L, with a median of 5.6 mmol/L, a minimum of 3.9 mmol/L, and a maximum of 18.3 mmol/L. The median glucose level was 0.2 mmol/L lower than the national average. No statistically significant difference in blood glucose levels was found between males and females (p = 0.135). By job position, elevated blood glucose levels (prediabetic range) were found in 62.5% of service workers, 40% of laboratory staff, 35% of electricians, 71.4% of managers, and 55.6% of administrative employees. Conclusion The findings indicate an increasing trend in metabolic and cardiovascular risk factors among employees of Erdenet Mining Corporation SOE.
