This research was conducted to grasp the characteristics of excessive sodium intake and its related factors in Korean middle-aged workers to help prevent and manage cardio-cerebrovascular disease. Study subjects were 40-59-year-old workers (n=1,438) who took part in the 2010 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into: 1) a group that ingested more than 4,000 mg of sodium per day and 2) a group that ingested less than 4,000mg of sodium/day. We analyzed the relationship between general characteristics, sodium-related disease, health behaviors, and frequency of eating out with excessive sodium intake. The proportion of subjects with sodium intake of more than 4,000 mg/day was high in men, smokers, and drinkers. As educational level and frequency of eating out went up, so did the proportion of subjects with sodium intake more than 4,000 mg/day. It's necessary to educate the public and create policies regarding sodium reduction in middle-aged men for the prevention and management of cardio-cerebrovascular disease, and various approaches are necessary to reduce overall sodium intake in the restaurant environment.
