Associations of urinary sodium levels with overweight and central obesity in a population with a sodium intake.

ABSTRACT: Background:Previous studies have reported an association between dietary sodium intake and overweight/central obesity. However, dietary survey methods were prone to underestimate sodium intake. Therefore, this study investigated the associations of calculated 24-h urinary sodium excretion, an index of dietary sodium intake, with various obesity parameters including body mass index (BMI) and waist circumference (WC) in a population with a relatively high sodium intake. Methods:A total of 16,250 adults (aged ?19 years) and 1476 adolescents (aged 10-18 years), with available information on spot urine sodium levels and anthropometric measurements from the Korea National Health and Nutrition Examination Survey (KNHANES) were included in this study. We calculated 24-h urine sodium excretion levels from spot urine sodium levels using the Tanaka formula. Results:In adults, those with high sodium excretion levels (? 3200 mg) showed increased odds of overweight and central obesity compared to those with low urinary sodium excretion level (
