Sažetak
Objective: Our aim was to analyze sodium and potassium intake in obese normotensive and hypertensive subjects from rural area. Design and method: Out of 1582 subjects (random rural sample) enrolled in ENAH study conducted in 2008–2010, 739 were invited for the second visit in 2015 and 377 subjects with reliable both urine samples (urine creatinine in normal ranges) were included in further analyses s (80m 297w ; average age 52 ± 13.5). Blood pressure was measured three times (Omron M6) and mean values were calculated. Fasting blood and first morning (spot) urine samples were collected. Sodium and potassium were determined using Tanaka, Kawasaki and Intersalt equations. Potassium intake was further adjusted for intestinal intake (77%) and renal excretion (92%). Optimal, normal, high normal BP, untreated and treated hypertension (HT) were diagnosed in 20.9%, 15.3%, 12.9%, 19.1% and 31.5%, respectively. There were 21.2%, 35.3% and 42.8% subjects in the BMI 1 (<25), BMI 2 (25–30) and in BMI 3 group (>30) group, respectively. Results: Significant differences in HT prevalence were observed among the BMI groups (46.9%, 63.6%, 80 %, respectively ; p = 0.001). Sodium excretion were significantly lower in BMI1 vs BMI3 groups (BMI < 0.0001). More than 10 g/day of salt intake was most seldom present in BMI1 and more frequently in BMI3 group (41.9%, 54.5%, 63.1%, respectively ; p < 0.05). Compared to normotensive in hypertensive subjects salt intake >10 g/day was significantly more frequently presented in overweight (X2 = 12.68 ; p = 0.0003) but not in obese subjects. Potassium intake was significantly higher in BMI3 than in BMI1 group (p < 0.001). No differences in Na/K ratio were observed among BMI groups. Conclusions: Higher salt intake contributes to high prevalence of hypertension and according to our results is more closely associated with hypertension in overweight than in obese subjects. No difference in Na/K ratio among BMI groups reflects high sodium and poor potassium intake in all subjects.
