Introduction: Despite the fact that excessive salt consumption is a risk factor in the development of a number of diseases. There is no doubt that dietary intake of sodium chloride remains well above recommended levels. The aim of our study was to evaluate the effectiveness of the Exsel Test in detecting excessive salt consumption in type 2 diabetic patients.

Methods: This was a cross-sectional study of 106 type 2 diabetic patients hospitalised in department A of the National Institute of Nutrition and Food Technology in Tunis. Each patient benefited from a physical examination, a biological check-up and an Exsel Test.

Results: The mean age was 55.46 ± 7.51 years. The majority of patients were women (57). The mean BMI was 29.68 ± 5.92 kg/m.2 We noted a significant difference (P=0.001) in BMI between patients with a positive Exsel Test and those with a negative test. In our study, the Exsel test was associated with the frequency of consumption of salted cheese (P=0.001), tinned food (P=0.005), dried fruit (P=0.01), variants (P=0.005) and sauces (P=0.03). The mean 24 h natriuresis was reported as 106.45 ± 63.82 mmol/24 h and the mean salt intake predicted by natriuresis as 6.22 ± 3.73 g/. The kappa test for comparing the relationship between the exsel test and predicted salt intake was 0.9 and the chi-square was 0.7. The sensitivity of the self-questionnaire was 25%, specificity 74%, PPV 4% and NPV 96%. The area under the curve was equal to 0.577, which is a very low value for a threshold of positivity for the Exsel Test self-questionnaire.

Conclusions: We suggest improving the Exsel test to adapt it to people’s culinary habits.
