Estimating daily salt intake based on 24 h urinary sodium excretion in adults aged 18-69 years in Shandong, China.

ABSTRACT:

Objective

24 h urinary sodium extretion was used to estimate the daily salt intake of shandong residents aged from 18 to 69 years in China.

Setting

20 selected counties/districts in Shandong stratified by geographic region (Eastern, Central Southern and North Western) and residence type (urban vs rural).

Participants

Among 2184 randomly selected adults, 2061 provided usable 24 h urine samples. Urine volume <500 mL or male creatinine <3.81 (female creatinine <4.57) are not included in the analysis.

Results

The mean sodium level excreted over 24 h was 237.61 mmol (95% CI 224.77 to 250.44) mmol. Overall, the estimated mean salt intake was 13.90 g/day (95% CI 13.15 to 14.65). The mean salt intake among rural residents was higher than that among urban residents (14.
