The purpose of this study was to compare the nutrient intakes, blood pressure, and biochemical values and lipid profile in blood according to smoking status. Subjects were recruited from Korean adult men, which included non-smoker (n=47), smoker (n=58), and ex- smoker (n=44) . Anthropometrical measurement, blood pressure measurement, dietary intake assessment using 24-hour recall method, and blood collection and analysis were conducted. The average age, height, weight, and BMI of the subject were 54.7 years, 165.8 cm, 67.3 kg, and $24.5\;kg/m^2 $, respectively. There was no significant difference in general characteristics among three groups. The mean daily intakes of energy and protein were 1740.9 kcal and 69.6 g. The daily folate intake of the smoker was significantly lower than that of the non- smoker or ex-smoker. However, cholesterol intake of the smoker was significantly higher than two groups. The daily total food intake was 1250.0 g for non-smoker, 1180.1 g for smoker, and 1237.5 g for ex-smoker. The mushrooms intake in the smoker was significantly lower than that in the ex - smoker. However, eggs intake of the smoker was significantly higher than two groups. The RBC count and serum GOT/GPT of the subjects were $4598.2\times1000/mm^3$ and 27.3/27.3 U/L. The WBC count, hematocrit and hemoglobin of the smoker were significantly higher than those of the non-smoker and ex-smoker. Blood pressure and serum lipids of the subjects were 128.3/75.5 mmHg for SBP/DBP, 180.2 mg/dL for total cholesterol, 160.8 mg/dL for triglyceride, 41.5 mg/dL for HDL-cholesterol, 106.5 mg/dL for LDL-cholesterol, and 3.5 for atherogenic index. Especially serum triglyceride of smoker was significantly higher than that of non-smoker. The above results revealed that some nutrient intakes, such as folate and cholesterol, and hematological findings, and serum triglyceride of the smoker were different from non-smoker. However, these differences were recovered to non-smoking status by prohibition of smoking. Therefore, in order to stop smoking, the effect of smoking on nutritional and health status should be informed to smoker and more systematic study should be conducted.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Purpose: This study examined the association between the antioxidant vitamin intake and obesity in Korean women. Methods: Adult women aged ${\geq}19years$ who completed a health examination and nutrition survey from the Korea National Health and Nutrition Examination Survey between 2007 ~ 2016 were selected for the study (n = 30,425). A BMI ${\geq}25kg/m^2$ and waist circumference ${\geq}85cm$ were defined as obesity and abdominal obesity, respectively. The individual antioxidant vitamin intake was estimated by linking the antioxidant vitamin composition database of commonly consumed foods and the subjects' 24-hour recall food consumption data. Carotenoids, retinol, vitamin A (retinol activity equivalent), vitamin C, tocopherols, and vitamin E (${\alpha}$-tocopherol equivalent) were included in the analysis. Each vitamin intake was converted to the nutrient density per 1,000 kcal. Odds ratio (ORs) and 95% confidence interval (CI) for obesity according to each tertile of the nutrient density was obtained from multiple logistic regression adjusted for age, household income, education level, smoking, alcohol consumption, and physical activity. Results: The mean intake of ${\alpha}$-carotene, retinol, vitamin E, ${\alpha}$-tocopherol, and ${\gamma}$-tocopherol per 1,000 kcal was significantly lower in the obese group than in the normal group. A higher intake of lycopene was inversely associated with obesity (highest vs. lowest; OR = 0.89, 95% CI: 0.83-0.96) and abdominal obesity (highest vs. lowest; OR = 0.88, 95% CI: 0.81-0.95). Higher intakes of ${\alpha}$-carotene, total carotenoids, vitamin A, and ${\gamma}$-tocopherol also had a negative relationship with abdominal obesity. The antioxidant vitamin intakes from eggs, milk and dairy products, seasoning, and grains were significantly lower in the obese group than in the normal group. Conclusion: This study showed that the dietary intake of antioxidant vitamins was inversely associated with obesity and abdominal obesity among Korean women. Further study will be needed to examine the causal relationship between the antioxidant vitamin and obesity.

Purpose: The aim of this study was to estimate total sugar intake and sugar intake-related dietary habit and nutrient intake of elementary school students. Methods: Subjects included 701 elementary school students (351 boys and 350 girls) residing in Jeju. The research analyzed a sample and was carried out using the 24 hour recall method and one day consumption of total sugar. Results: The average daily total sugar intake was 55.3 g (male 53.1 g, female 57.6 g). Total sugar intake per meal was 6.3 g (11.4%) from breakfast, 6.9 g (12.5%) from lunch, and 7.2 g (13.0%) from dinner, 34.9 g (63.1%). Major food groups of total sugar were milks (17.04 g), grains and their products (12.79 g), fruits and their products (9.40 g), and sugars and sweets (7.30 g). In analysis of the amount of total sugar consumption from several recipes, much was taken in from dessert and snacks such as dairy products (15.08 g), bread and snacks (6.4 g), beverages (5.5 g), fruits (5.1 g), and ice cakes (4.8 g). Total sugar consumption was high for rices and side dishes such as noodles (5.1 g), stir-fried foods (2.3 g), fried foods (1.4 g), cooked rice with seasoning (1.4 g), and hard-boiled foods (1.1 g). In comparison of total sugar consumption for sugar sources, daily intake of natural sugar, added sugar, and natural and added sugar were 25.8 g, 23.3 g, and 6.2 g, respectively. High sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, and niacin than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of fifth graders of elementary schools on Jeju Island was 55.4 g/day, and it was usually intake from snacks. Therefore, elementary school students need nutritional education for proper selection of better snacks and for reduction of dietary sugar intake.

Purpose: The aim of this study was to estimate total sugar intake and sugar intake-related dietary habit and nutrient intake of middle school students. Methods: Subjects included 1,184 middle school students (476 males and 708 females) residing in Jeju. This research analyzed daily dietary intakes of subjects using the 24 hour recall method and surveyed the dietary habit related to total sugar intake using questionnaires. Descriptive analysis, chi-square test, t-test, and ANOVA, using the SAS program were used for analysis of data. Results: The average daily total sugar intake was 60.3 g (male 50.5 g, female 66.9 g). Total sugar intake per meal was 6.5 g (10.8%) from breakfast, 9.0 g (14.9%) from lunch, 11.8 g (19.6%) from dinner, and 33.0 g (54.7%) from snacks. Food groups that contribute to the majority of total sugar intake were grains and their products (23.0 g), milk (11.0 g), fruits and their products (7.3 g), sugars and sweets (6.1 g), and vegetables and their products (5.8 g). In terms of total sugar intakes by cooking methods, desserts showed a greater amount than main and side dishes, and indicated in order of amount as follows: bread and cookies (11.5 g), dairy products (7.5 g), ice cakes (6.2 g), beverages (5.3 g), and fruits (4.5 g). Total sugar consumption was high for rice and side dishes such as noodles (10.2 g), fried foods (2.9 g), stir-fried foods (2.0 g), and cooked rice with seasoning (1.7 g). The daily intake of natural sugar, added sugar, and natural and added sugar was 18.3 g, 35.8 g, and 6.2 g, respectively. The high sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, vitamin B6, niacin, and vitamin E than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of second graders of middle schools on Jeju Island was 60.3 g/day, mostly obtained from snacks (54.7%). Therefore, nutritional education for proper selection of better snacks and for reduction of dietary sugar intake is needed for middle school students.

To assess the food intake and diet quality of high school students who live in Chuncheon area, a dietary survey using 24-hour recall method was conducted with 318 subjects. $71.4\%$ of total food intake was in the form of plant foods and the rest on the form of animal food. Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When counting the major food groups consumed, $37.1\%$ of subjects had a DDS of 3 and $48.4\%$ of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only $14.5\%$ of subjects consumed foods from all five groups. On average, subjects habitually consumed 26.7 different foods daily, with the mean score of diet variety for males (27.3) being significantly higher than for females (25.8) . Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.39 for vitamin $B_2$ to r=0.61 for phosphorus. NAR also improved as the number or foods or rna groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food group and have various foods in their diet.

The purpose of this study was to estimate seasonal variation of nutritional intake and quality in adults in longevity areas. Dietary survey was given to 469 subjects over age 20 living Bukjeju-gun, Yecheon-gun, and Sunchang-gun of Korea, using 24-hour recall method every 4 seasons over one-year period. The mean daily intakes (%RDA) of 4 seasons were 1313.3 ㎉ (72.0%) for energy, 47.3 g (82.2%) for protein, 20.2 g for fat, 228.0 g for carbohydrate, 12.8 g for dietary fiber. The differences were hardly significant among the seasons. Mean daily intakes of most of the vitamins and minerals were lower than RDA except vitamin C and folate, especially %RDAs of Ca, vitamin D, vitamin B$_2$, vitamin E were less than 60% of RDA. In general, nutrient intake were high in spring compared to other seasons except vitamin C which was high in fall and winter. Mean daily intakes of cholesterol were 151.7 mg and 124.3 mg in males and females, respectively. The differences was significant between the two sexes but not among the seasons. PUFA : MUFA : SFA ratio of the subject was 1.0 : 1.3 : 1.2. Average CPF ratio of energy intake was 72.7 : 14.4 : 12.9, and energy intake ratio from carbohydrate was low in spring, in contrast energy intake ratios from protein was significantly high in spring. Mean adequacy ratio (MAR), an index of overall nutritional quality was 0.64 for female and 0.71 for male. The indices of nutritional quality (INQ) were over 1 for most of nutrients except 0.73 of Ca, 0.87 of vitamin A, 0.69 of vitamin B$_2$, and 0.65 of vitamin E. Both MAR and INQ were significantly different among sex and seasons, values were higher in males than in females and were higher in spring with the exception of vitamin C. In conclusion, subjects in longevity areas did not consume enough nutrients quantitatively as well as qualitatively, especially Ca, vitamin A, vitamin B$_2$, and vitamin E. Also mean daily intakes of most of vitamins and minerals were insufficient in females, and were significantly different among season. Therefore we must consider a counterplan to augment nutrition intake for them. In addition, it seems to be essential to micro nutrients to the food composition database to estimate dietary intakes more accurately.
