Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

The aim of this study was to explore the relationship between demographic characteristics and atopic dermatitis, along with adolescents' body mass index. Also, this study explored the association between dietary intakes (fruits, soda, caffeinated beverages, instant food, cracker, vegetables, and milk) of adolescents and atopic dermatitis. Korea Youth Risk Behavior Web-based Survey for 2014 was used for data analysis, in which a total of 3,532,149 middle and high school students participated. Data were analyzed by descriptive analysis and logistic regression based on the complex sample design using SPSS ver.20.0 statistics. The results showed that males had a higher prevalence rate of atopic dermatitis than females. The significant association between body mass index and atopic dermatitis was found (F=46.625, P<0.001). Students who have higher levels of body mass index showed a higher prevalence rate of atopic dermatitis. Finally, the findings showed that the intake of vegetable and milk had associations with atopic dermatitis (F=6.795, P<0.001). Greater vegetable intake was associated with less atopic dermatitis whereas greater milk intake was associated with more atopic dermatitis prevalence. Based on the above results, we found that demographic characteristics, body mass index, and some dietary food intakes of adolescents had influences on prevalence rate of atopic dermatitis.

This study was performed to show change of fat-free mass(FFM), representing mostly the muscle mass change, and muscle strength with increasing age, and relationship between dietary, exercise behaviors and FFM in healthy middle-and old aged women who are of age over 55 years. The FFM and correspondingly hand grip strength showed significant positive correlation with age. But concentration of serum albumin showed no significant relationship with age. The subjects were categorized into groups according to FFM tertile. The anthropometry such as weight, BMI, fat mass, circumferences of waist and hip, WHR, and hand grip strength decreased significantly in the lowest FFM group. But the albumin level showed no change according to FFM level. The FFM showed significant correlation with nutrient intakes such as energy, carbohydrate, protein, Fe, P, Ca. No association, however, was shown with exercise behavior probably because of no case with resistance exercise habits. The variance of FFM was explained 55.2% by height and carbohydrate intake. The variance of height-adjusted FFM could be explained only 16.2% by intake amount of carbohydrate. In conclusion, the decrease of FFM may cause to reduce muscle strength in female elderly. The increasing nutrient intakes were associated with the increased FFM and may protect from risk of sarcopenia. However, only the carbohydrate intake could influence independently the FFM in middle- and old-aged women. The FFM has no association with endurance exercise habits.

The purpose of this study was to categorize dietary lifestyles and analyze intake behavior regarding beverages according to lifestyles of 276 university students in Yeungnam region. Frequency analysis, factor analysis, cluster analysis, reliability analysis, one-way analysis of variance, and ${\chi}^2$ tests were conducted using SPSS V.21.0. In the factor analysis, dietary lifestyles were categorized into one of five factors: health-seeking type, popularity-seeking type, safety-seeking type, economy-seeking type and convenience-seeking type. According to cluster analysis, respondents were divided into four groups: convenience-seeking group, wellbeing-seeking group, popularity-seeking group, and indifference group. Chi-square tests showed that there were significant differences in gender, grade, dwelling status, and monthly allowance according to the four dietary lifestyle groups. The level of dietary habits and percentage of correct answers related to beverages of the wellbeing-seeking group were highest among the four groups. The frequency of beverage intake was significantly different for carbonated drinks, milk and dairy products, and sport drinks according to dietary lifestyle groups. In addition, for beverage preference, there were significant differences in carbonated drinks, sport drinks, tea and functional drinks according to dietary lifestyle groups.

To examine the eating attitudes, weight concerns, dietary intake, and menstrual function of Korean female elite athletes, 109 subjects in seven sports disciplines (rhythmic gymnastics, synchronized swimming, badminton, volleyball, Taekwondo, field hockey, and soccer) responded to a questionnaire consisted of three parts; eating attitudes and behavior(Eating Attitude Test-26; EAT26), body weight perception (Body Dissatisfaction Index: BDI) and weight control behavior, and menstrual history and status. They also recorded three-day dietary intake. Body weight (43.6$\pm$4.3 kg) and body mass index (16.7$\pm$1.4 kg/$m^2$) in rhythmic gymnasts were lower than those in other athletes (P<0.05). EAT26 scores were not different among sport events (12.3$\pm$6.5 total), however, eating disturbances (EAT26 score$\geq$20) were highly prevalent in aesthetic athletes ($30\%$) than in others ($5\%$). More than half of the athletes perceived themselves overweight and four fifth of the athletes desired to reduce weight about 4.4 kg. The gymnasts consumed the lowest caloric intake (1028:t371) while the volleyball players did the highest (2995$\pm$342 kcal/d) (P<0.05). The BDI score was not different among sport events. Three fourth of the athletes experienced weight control, and the most frequently used weight reduction method was exercise followed by using robber suits, diet, and sauna. About $40\%$ of the subjects reported irregular menstrual cycles, but menstrual dysfunction ($\leq$6 menses/yr) was only $5\%$. Generally, the Korean female elite athletes desired to reduce weight from their current body weight. No differences in eating attitude and body dissatisfaction were noticed among athletic disciplines. However, eating disturbances were highly prevalent in aesthetic athletes who also reported much less energy intake than the recommend daily energy intake. It appeared that weight reduction methods were not properly practiced in these population. Menstrual dysfunction was minimally reported.

This study was performed to understand recognition and behaviors related to sodium intake of Korean adults. The data were collected from subjects including 267 male and 285 female adults in nationwide and compared by gender and by age. We found that the male group showed significantly higher smoking, alcohol drinking, and exercise does the female group. The older group (40 to 59 years) revealed significantly higher exercise and lower alcohol drinking; however general disease and hypertension prevalence, diet therapy practice, and meditation for hypertension were higher. Recognizing sodium levels of foods containing high-sodium, and sodium-nutriture labels when purchasing foods, and knowing differences between salt and sodium of the male group or recognizing sodium levels of foods containing high-sodium of the older group was worse than the other. Among the 32 food behaviors, only 12 were identified as significantly correlated to sodium intake levels including behaviors of preferring Chinese and Japanese foods to Western foods, preferring kimchi to raw vegetables, completely consuming soup, stew, noodle liquid, liking of dried fish and salted mackerel, frequent eat-outs or delivered foods, and so forth. There were significant differences between gender or age groups in terms of sodium intake-increasing behaviors; the male group showed higher behaviors of preferring salty taste and eating all broths. And the older group revealed higher behavior of adding table salt as well as the previous two, however, the younger group showed more behaviors of eat-outs or delivered foods and not the liquid of kimchi.

This study examined the difference of dietary intake behavior between groups of adults aged >20 years with or without dyslipidemia, and comparing the various types of dyslipidemia, based on the Seventh (2016) KNHANES. Men showed higher rate for triglyceridemia and LDL-cholesterolemia than women and subjects in the age group 50-59 years exhibited the highest incidence of triglyceridemia, total cholesterolemia and HDL-cholesterolemia. The ratio of obese people was higher in most types of dyslipidemias. The top five foods in each group of cereal & grain, meat, vegetable, and fruit were selected for analysis, based on the food frequency. The dyslipidemia group showed higher intake frequencies for mixed grains, cabbage kimchi and leafy vegetable than the no-dyslipidemia group, and the group with high blood total cholesterol for mixed grains, apple, and cutlassfish-croaker. Group with high blood triglyceride showed higher intake frequencies of rice and mackerel-mackerel pike than the other groups of high blood triglyceride. No food showed significant difference in the frequencies between groups of LDL-cholesterol. Group with high blood HDL-cholesterol showed higher intake frequency of bibim-fried rice, deep fried chicken, stir fried chicken, apple, tangerine, banana and butter-margarine. These results indicate that people with high levels of blood total cholesterol are more concerned with food having health benefits than those with abnormal levels of other blood lipid. More information on dietary benefits need to be provided to patients having high levels of triglyceride, LDL-cholesterol and HDL-cholesterol.

This study was performed to examine the food behavior and dietary fiber intakes of high school girls using questionnaires and 24-hr recall method. Collected sample were 263 girls from 4 different high schools. The dietary intakes were analyzed by the DS24 WIN program. The average height and weight of the respondents were $161.0{\pm}5.0$ cm and $51.8{\pm}6.3$ kg. The average BMI was $20.2{\pm}2.2$ which was within the normal range. The breakfast skipping rate was 39.2% and the reason of breakfast skipping were lack of time(50.0%), irregular meal time due to eating between meals(17.0%) and poor appetite(13.7%). The average daily energy intake of the respondents was 1741kcal. Beside protein, phosphorus, iron, niacin, vitamin A, and B1, all other nutrients intake level were below the recommended intake(RI). Average calcium and folate intakes were below the EAR as of $59.5{\sim}89.7%$ and $63{\sim}83%$ respectively. The average dietary fiber intake of the subjects was $15.6{\pm}5.2$ g, between 3.4g-35.2 g, and the respondents coumed $9.2{\pm}2.6$ g/kcal of dietary fiber. The main sources of dietary fiber were rice and kimchi which supplied 14.75% and 13.66% of total dietary fiber respectively. Also the major food groups supplying dietary fiber were vegetables and cereals, 36.90% and 31.06% of total dietary fiber respectively.

The purpose of this study was to evaluate a nutrition education program designed to reduce sugar intake in preschool children. The nutritional knowledge, dietary attitude, dietary behavior, and food intake with a sweet taste in preschool children were tested before and after 4 weeks of nutrition education from March 8 to April 1, 2016. The preschool children were recruited in Dobong-gu, Seoul. The subjects were divided into two groups; educated (N=59) and non-educated group (N=40). Statistical analyseis were performed using SPSS 22. The nutritional knowledge about sweet tasting food was significantly increased (P<0.01) in the educated group and significantly decreased (P<0.01) in the non-educated group. The dietary attitude toward sweet tasting food was significantly decreased (P<0.05) in the educated group but not significantly changed in the non-educated group. The dietary behavior toward sweet tasting food was significantly decreased (P<0.05) in the educated group and significantly decreased (P<0.01) in the non-educated group. The major food sources of sugar intake were not significantly changed in either groups. The major food sources of sugar intake in the 5 years old children were yogurt products>sweetened breads>cookies/biscuits>chocolate>cereals>beverages>sweetened milk>sweet spicy chicken>Tteokbokki. Although there are some limitations in this study, due to the short length of the nutrition education and lack of active participation by the parents, the results suggest that effective nutrition education on sweet tasting food can bring about changes in nutritional knowledge as well as dietary attitude.

The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.
