Abstract 11809: Sodium Intake is Correlated to Total Calorie Intake and Potassium
Background: Selecting lower-sodium diets are not successful to reduce sodium intake in general population. If systemic approach is considered lowering sodium intake because of the culinary tendencies, we need to aware of the quantitative relationship between nutrients and sodium in daily usual food of the general population.
Hypothesis: We assessed the hypotheses that are the positive correlation between total calorie intake, potassium and sodium intake; the cutoff values for sodium recommendation (≤2300 mg per day).
Method: We studied 55,544 individuals who completed health examination and nutrition survey in 168,157 randomly selected participants that could represent the country from the 1998-2013 Korea National Health and Nutrition Examination Survey (KNHANES). The nutrition survey was 24 hours recall method to estimate the amount of standardized Korean food. We analyzed the quantitative relationship, and estimated the cutoff value of the total calories and potassium at the recommendation of the sodium intake.
Result: The mean values were total calorie 1922±834 Kcal, sodium 4904±3218 mg, potassium 2935±1563 mg, protein 70±41 g (15% in total calorie), fat 37±31 (18%), and carbohydrate 312±123 (67%) in mean value. The standardized coefficients were potassium 0.309, protein 0.226, fat 0.070, carbohydrate 0.097 in model 1 (R2=0.402); total calorie 0.271 and potassium 0.368 in model 2 (R2=0.384) with cardiovascular risk factors in multiple linear regression analysis (table). The optical cutoff value of the total calorie for sodium 2300mg is 1520 Kcal (74% sensitivity, 74% specificity, 93% positive predictive value, 38% negative predictive value, area under the curve: 0.826, 95% CI: 0.82 to 0.83 ; p < 0.001) and the potassium is 1956 mg (82% sensitivity, 69% specificity, 92% PPV, 44% NPV, AUC: 0.825, 95% CI: 0.82 to 0.83 ; p <0.001).
Conclusion: In conclusion, the cutoff values for the sodium 2300 mg are the total calorie 1520 Kcal and potassium 1956 mg.
