Abstract:
In 2016, the median of 24-hour urinary sodium, sodium-to-potassium ratio, and sodium intake per capita of residents in Jiaodong area of Shandong Province were 161.7 ( IQR:120.5, 218.9) mmol/d, 3.4 ( IQR: 2.4, 5.0) and 9.5 ( IQR:7.1, 12.8) g/d, all were lower than that of 2011[193.3( IQR:149.2,243.3)mmol/d, 4.5( IQR:3.3,5.9), 11.3( IQR:8.7, 14.2)g/d] ( P<0.05); the median of 24-hour urinary potassium was 47.2 ( IQR:34.4, 66.5) mmol/d, higher than that of 2011[42.9( IQR:33.6,56.0)] ( P<0.05); the proportion of salt intake per capita per day exceeding 5 g (89.9%) was lower than that in 2011 (90.0%). The results of the generalized linear regression model showed that the 24-hour urinary sodium was positively correlated with systolic and diastolic blood pressure [β values were 0.04 (95% CI: 0.00, 0.07), 0.03 (95% CI 0.01, 0.05), respectively], and the sodium-to-potassium ratio was positively correlated with diastolic blood pressure [β(95% CI): 0.78 (0.09, 1.47)].
