Abstract


Background: Salt is directly related to hypertension and cardiovascular disease associated with it. As obesity facilitates the effect of salt, a quantification of obese salt intake is necessary.

Methods: Our patients numbering 56 have been recruited in the consultation of the obesity unit. Patients were given a questionnaire about their knowledge concerning salt. Natriuresis of 24 h was quantified. The average amount of sodium consumed per day from foods was determined (SAL), the average amount of sodium consumed per day from table salt added to cooking and seasoning (SAC) and the average total amount of sodium consumed per day (STOQ).

Results: The mean age of our patients was 44.31 ± 12.8 years. The average BMI of our patients was 37.12 ± 5.9 kg/m2. The average systolic blood pressure was 123.8 ± 14 mmHg and mean diastolic blood pressure was 76.45 ± 10.7 mmHg. The average amount of sodium consumed per day from food (SAL) was 1 915 ± 1038 mg. The average amount of sodium consumed per day from cooking salt (SAC) was 2487 ± 1663 mg. The total amount of sodium consumed per day (STOQ) was 4402 ± 1831 mg. This addition is equivalent to 11 ± 4.6 g of salt per day. The total sodium intake exceeded 2000 mg/day in 89.2% of patients. More than half (57%) of spontaneous sodium intake comes from salt added. The average natriuresis in our population is 158 ± 68 mmol/24 h, higher than the norm in 18% of cases. The majority (85%) of our patients have claimed that excess salt is bad to very bad for health.

Conclusion: Our study showed the importance of salt consumption in obeses and especially table salt and yet the majority of our patients consider it to be harmful to health.

It will be necessary to take into account the sodium intake when prescribing the diet.
