The purpose of this study was to analyze a cohort, age, and time effects on sodium and sodium-calorie intake using the 2007~2017 Korea National Health and Nutrition Examination Survey (KNHANES). For analysis, we have constructed cohort panel data that combine KNHANES data in a time series. The age effect gradually increased from age 45~49 and then decreased afterwards. The time effect showed an increase in average sodium intake until 2010 followed by a subsequent decrease. The cohort effect showed that the sodium intake was the highest for the War of Liberation 1946~1953, and that the younger the latter, the lower the sodium intake. According to a cohort analysis, the younger the generation, the lower the sodium intake compared to the calorie intake, according to the baby boomers. Based on the results of this study, efforts should be made to educate and promote the dieting and providing low-salt meals to reduce sodium intake by generation. An analysis of the health hazards including sodium by generation and age is thought to enable the establishment relevant policies.
