Nocturnal hypertension among treated hypertensive patients Pagmadulam sukhbaatar t, Burmaa Badrakh 2, Naranchimeg Sodovsuren, 2Tsolmon Unurjargal2 t Mongolia-Japan University Hospital of MNUMS 2 Mongolian National University of Medical Sciences Objectives of this study were to determine the prevalence of nocturnal hypertension in treated hypertensive patients and factors associated with its presence. Methods: This hospital based cross-sectional study included 160 hypertensive patients, who underwent 24-h ambulatory blood pressure monitoring. According to the national guideline for hypertension nocturnal hypertension was defined as mean night-time systolic blood pressur ≧ 120 mm Hg or mean night-time diastolic blood pressure ≧ 70 mm Hg. Cardiovascular risk factors (smoking, alcohol use, obesity, diabetes, lack of physical activity) were compared in hypertensive patients with and without nocturnal hypertension. Results: The mean age of the participants was 62.4 years and 42.5% were men. Approximately 15% and 16.2% of all patients were current smokers and alcohol over users. 61.2% and 75% had obesity and physical activity lacking and 11.2% had diabetes. All patients were on blood pressure lowering medications, but 43.7% of patients were taken only one medication for high blood pressure. Mean night-time systolic blood pressure and diastolic blood pressure were in men and women 140.6 ± 20.2 mm Hg and 86.5 ± 11.2 mm Hg and 145.6 ± 17.1 mm Hg and 79.8 ± 7.3 mm Hg respectively. The nocturnal hypertension was detected in 61.6% of patients (64% in male, 60% in female). Our study revealed that nocturnal hypertension was significantly higher in patients with diabetes and obesity than in patients without diabetes and obesity. Conclusion: The prevalence of nocturnal hypertension was high. Nocturnal hypertension among treated patients was associated with diabetes, obesity and mono therapy.
