Abstract

Objective To analyze the association between 24-hour urinary sodium excretion and obesity in a general Chinese population aged from 18 to 69 years old. Methods 2 400 from 18 to 69 year-old subjects were selected from four counties in Shandong Province and Jiangsu Province from 2013 to 2014 by using multi-stage stratified cluster random sampling method. Questionnaire survey, physical measurement and 24-hour urine collection were conducted. The relationship between urinary sodium and obesity was analyzed by multivariate linear regression and Logistic regression analysis. Results 2 275 subjects were finally included in the analysis. Obesity rate of the subjects was 19.1%(95% CI: 17.4%-20.6%)and 24-hour urinary sodium was (166.4±71.5) mmol/d. The urinary sodium in obese, and central obesity population calculated according to waist-to-height ratio (WHtR) were higher than the normal population, respectively (All P < 0.05). Multivariate linear regression analysis showed that after adjusting for relevant factors, 24-hour urinary sodium was positively correlated with body mass index (BMI), waist circumference (WC) and WHtR. Multivariate Logistic regression analysis showed that compared to population in the lowest quantile, population in highest quantile had an increased risk of being the obesity, abdominal obesity(calculated according to WC) and abdominal obesity(calculated according to WHtR) with OR(95% CI) of 1.61(1.18-2.20), 2.01(1.39-2.89) and 1.47(1.15-1.89), respectively, after adjusting for age, gender, education, smoking, alcohol consumption, physical activity, hypertension and diabetes. Conclusions High sodium is independently associated with obesity. Sodium intake is a potential and important risk factor for obesity.
