초록	Salt intake is estimated from the amount of sodium excreted by 24-hour urine collection, the ratio of sodium to creatinine levels in urine at any given time, and the frequency of food intake. However, it can be said that it is not fully used due to its usability and insufficient consideration of the accuracy of the estimates. Therefore, we developed a self-administered salt questionnaire (Table.1) and examined the accuracy of the salt questionnaire based on its correlation with the estimated salt intake by 24-hour urine collection. We also developed a mobile phone response method using Microsoft Forms. A total of 112 patients with CKD were subjected to a self-administered salt intake questionnaire and 24-hour urine collection. Considering that the "intake per serving" is different even if the same dish is eaten, the "salt intake per serving" was corrected by body weight by partial correlation analysis. (1) The correlation between the self-administered salt questionnaire and the estimated salt intake by 24-hour urine storage after weight correction was shown in Fig.1 (r=0.60, p<0.01). (2) We were able to obtain a correlation coefficient equivalent to that of comparing the estimated salt intake from the urine at any time according to Tanaka's formula, which is currently used in many clinical settings in Japan, with the estimated salt intake from our self-administered salt questionnaire. If we can know our salt intake and its source, such as measuring your blood pressure and weight, or taking a blood test, it is expected to increase your motivation to reduce salt and contribute to the realization of salt reduction. In addition, we would like to spread the method of answering questions using Microsoft Forms, which allows you to estimate salt intake at home without having to come to a hospital or clinic.
