Objectives: To evaluate total salt intake in the adult population through an analysis of sodium in 24-h urine samples in two regions of Belgium. Methods: Urine samples were collected over 24 h from participants and they had to complete a specific questionnaire about salt intake afterwards. Sodium and creatinine concentrations were analysed in these samples. Subjects: The target population comprised adults aged 45-65 years in the region of Ghent and Liege. A total of 123 and 157 volunteers from Ghent and Liege, respectively, were included in the study. Results: The mean creatinine level in Flanders (n = 114) amounted to 0.173 +/- 0.035 mmol/kg/day, whereas in the Walloon region (n = 135) it amounted to 0.161 +/- 0.036 mmol/kg/day, after the exclusion of subjects with incomplete urine collection. Intake of sodium in Flanders (n = 114) was 4.29 +/- 1.29 g/day, whereas in the Walloon region (n = 135) it was 3.94 +/- 1.44 g/day. In both regions, sodium intake in men was higher than in women. Conclusion: Salt intake was more or less twice as high as the recommended intake. Salt intake as estimated from 24-h urine collections is substantially higher than that previously calculated on the basis of food consumption data. A salt reduction programme for Belgium is primordial. European Journal of Clinical Nutrition (2010) 64, 1260-1265; doi: 10.1038/ejcn.2010.148; published online 18 August 2010
