Objectives: This study aims to survey the prevalence and risk factors of hypertension (HTN) among nurses. Methods: Data was collected from 528 nurses of 23 hospitals in Ulaanbaatar (UB) and local hospitals in other regions. We randomly selected day-shift only nurses (264) and shift nurses (264), collected blood samples, administered a health survey questionnaire, and processed data with SPSS 19.0 statistic software. Results: Overall, 8% of participants who work for shift and 7.2% of day working nurses are smokers (p<0.0001). 3.2% of shift working nurses and 3.8% day working nurses use overuse alcohol (p<0.0001). The day working nurses and the shift working nurses and compared their BMI to measured normal (42.1% and 36.4%) overweight (39.7% and 43.9%), obesity (18.2% and 19.7%) (p<0.02), central obesity normal (39.4% and 34.5%), and central obesity≥ 80 (60.6% and 65.5%), body fat percentages are normal (29.2% and 16.1%) and increase (70.8% and 73.9%), visceral obesity are normal (65.9% and 63.3%) and increase (34.1% and 36.7%). Nurses (day-work and shift-work) who have arterial HTN are detected by normal (72.3% and 59.1%), prodromal period (14.4% and 16.7%), 1st stage (12.1% and 19.7%), 2nd stage (1.2% and 4.5%) (p<0.002). Working time of nurses detected that shift working nurses’ arterial hypertension amount is higher than day time working nurses. Conclusion: 24.2% of shift working nurses have HTN is showed that higher than day time working nurses. Hypertension is directly related to overweight, obesity, visceral obesity and high blood glucose level. (p<0.0001).
