Purpose: The nutrient intake status of the groups classified by smoking amount, drinking frequency, and obesity were compared using data from the Eighth (2019) Korea National Health and Nutrition Examination Survey to examine the relationship of nutrient intake status with heath behavior in adults. Methods: This study analyzed the nutritional intakes of 4,379 people over 19-years old and compared nutrient intake amount (NIA) and density (ND), and ratios of nutrient intake (%DRI) and subjects intaking less (< DRI) compared to the daily dietary reference of the groups divided by health behaviors including smoking amount, drinking frequency, and obesity status. Results: NIA of dietary fiber, vitamin A, folic acid and vitamin C was lower in smoker groups compared to non-smoker group and ND of those decreased with smoking amount.%DRI of dietary fiber and vitamin C was also lower and < DRI of those higher in smoker group. NIA and ND of dietary fiber and vitamin C, and %DRI also decreased with drinking frequency. NIA of energy, protein, saturated fatty acid, iron, thiamin, and niacin was the highest in overweight group by body mass index (BMI), NIA of fat and sodium increased with obesity by BMI, and only sodium was higher in obese group by waist circumference. Lower consumption of dietary fiber and vitamin C in the groups of higher smoking amount and drinking frequency, and higher consumption of fat and sodium in obese groups imply the dietary problem to be improved. Conclusion This result implies that the nutritional status of the groups of smoking, drinking, or obesity have been improved but more effort is required to sustain the health diet at the same time.

Purpose: The nutritional status of folate in Korean adults was evaluated using the newly established folate database (DB) and data from the 7th Korea National Health and Nutrition Examination Survey. Methods: This study analyzed the folate intake of 15,054 people (6,278 men and 8,776 women) and the relationship with serum folate concentration of 5,260 people (2,272 men and 2,988 women). Results: The average daily folate intake among Korean adults was lowest in the 19 to 29-year age group and highest in those in their 50s. Folate intake was higher in groups with higher education and household income, non-smokers, participants in aerobic physical activity, and dietary supplement users regardless of sex. Among men, office workers consumed more folate than physical workers. Vegetables and grains were the first and second most contributing food groups to folate intake. The serum folate levels were higher in women than men and lowest in the 19–29 year age group for both sexes. After adjusting for energy intake, age, income, smoking, physical activity, and dietary supplement intake, serum folate concentration increased significantly as intake increased (p < 0.001). The explanatory power (R2 ) of folate intake on the blood folate concentration was 0.183 and 0.141 in men and women, respectively. Conclusion The proportion of participants consuming less than the estimated average requirement was 48.1% and 65.3% in men and women, respectively. In particular, the folate intake and serum levels of young men aged 19–29 years were the lowest. Therefore, it is necessary to improve their folate nutritional status through a balanced diet. In addition, the newly established folate DB may be useful for evaluating the folate nutritional status of Koreans.
