Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

Objectives: This study evaluated the association between osteoarthritis (OA) and health-related quality of life (HRQoL) in elderly Korean women. Methods: We selected participants (n=2,597) aged 50 years or older from Korea National Health and Nutrition Examination Survey [KNHANES] 2005-2008. Demographic and personal characteristics, medical history of OA, and EQ-5D were extracted from the KNHANES data. Results: We found that demographic variables, including age, education level, income, and personal characteristics, were important covariates associated with the prevalence of OA and with HRQoL. In this study, OA was an important factor affecting HRQoL in women. The adjusted odds ratio for HRQoL in participants with OA was 2.92 [(95% confidence interval (CI)=2.43-3.51, p<.001)] in mobility, 2.60 (95% CI=2.17-3.10, p<.001) in pain/discomfort, 2.17 (95% CI=1.78-2.65, p<.001) in usual activities, 1.65 (95% CI=1.22-2.24, p=.001) in self care, and 1.47 (95% CI=1.22-1.77, p<.001) in anxiety/depression. After adjustment of covariates, HRQoL was significantly decreased in participants with OA. Conclusions: Our findings reveal that there is a strong association between OA and HRQoL. Preventing and controlling OA may significantly improve the quality of life for elderly Korean women.

This study investigated anthropometric and biochemical characteristics, food and nutrient intakes, and changes in body mass index (BMI) of Korean middle age men (40~49 yrs). Data on BMI, anthropometric (height, weight, waist circumference, body mass index, blood pressure), and biochemical (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, hemoglobin, GOT, GPT) characteristics, food and nutrients intakes, nutrient density, and index of nutrient quality were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2001, 2005, 2011). Subjects were divided into three groups by year. Weight, BMI, and hemoglobin increased significantly by year. All anthropometric factors except height showed a positive relation with BMI by year. Consumption of barley, chinese noodle, confections, soybean milk, egg, ice cream, pizza, fried foods, banana, coffee, and raw rice wine increased significantly by year. Intake ratios of nutrients except water and fiber were over 100% of KDRI generally. INQ according to intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, and niacin per 1,000 kcal increased significantly by year. Distribution of BMI status of subjects showed a significant difference by exercise. The findings of the present study show that BMI of subjects increased by year, and intakes of all nutrients except calcium and riboflavin showed aspects of overnutrition by year. Intakes of fruits decreased while intakes of raw rice wine and coffee increased by year. Therefore, practical and systematic nutrition programs are required to maintain optimum BMI and appropriate intakes of nutrients to maintain a desirable lifestyle and improve dietary life.

This study was conducted to investigate nutrient consumption by Korean adults in various places. To accomplish this, we used the 1998-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects of this investigation were over 19 years and the study included 37,160 people. The meals were categorized as breakfast, lunch, dinner, and snacks consumed at home, or while eating-out. Investigation of the rate of consumption at serving places based on daily meals and years showed that eating-out generally increased with time. The consumption of meals prepared at home was higher than that of meals consumed anyplace else in 1998, 2001, 2005, and 2007-2009. However, the rate of consumption of home meals decreased from 1998 to 2007-2009, while the rate of eating-out increased during this period. Annual nutrient intake according to serving places with respect to meals, energy, fat, and sodium were significantly lower in home meals than those consumed elsewhere in 2007-2009 relative to 1998. The sodium intake and energy distribution ratio of fat in meals consumed while eating-out increased significantly from 1998 to 2007-2009. The energy, fat and sodium intake and energy contribution ratio of fat consumed in meals at institutions was significantly higher in 2007-2009 than in 1998. Based on these results, additional research is required to develop guidelines for dietary life improvement at each serving place and to address education and policies for balanced nutrition intake.

The purpose of this study was to assess the level of quality of life and related factors among the elderly in Korea. In particular, we focused on factors affecting the quality of life of the elderly in long term care. We used the third Korean National Health and Nutrition Examination Surveys (KNHANES) from 2005. We sampled a total of 3,571 (10.5%) elderly from the national survey. We compared the mean of quality of life to socioeconomic status, Activities of Daily Living (ADL), health behavior, and disease variables. We used EuroQol-5D among KNHANES to assess the quality of life. In this study, the mean score of the quality of life among the elderly was 2.57. Logistic regression showed that the elderly who were male, with spouses, with health insurance, and with good ADL levels enjoyed higher quality of life scores and odds ratios than those who were female, divorced, uninsured, and with low ADL levels (p<.05). The quality of life of the elderly was affected by socioeconomic, ADL, health behavior and disease variables. To improve long term care and the quality of life among the elderly, we need detailed research to clarify the effects of these factors.

The principal objectives of this study were to identify diet problems associated with dining out, and to suggest dining out strategies for groups with diet problems. The data collected from adults(all over 20 years old) from the third Korea National Health and Nutrition Examination Survey III(KNHANES III), conducted in 2005, were used in this study. A total of 6,497 data were included in our statistical analyses, using SPSS 14.0. The results of this study demonstrated that there were significant differences in dining out frequency between different genders(p<0.001), ages(p<0.001), and economic status (p<0.001). With the crosstabulation analysis using the Chi-square statistics, the middle class males aged $20{\sim}29$(p<0.05), and lower class females aged 65 and over evidenced different degrees of compliance with the following guidelines. 'Eat a variety of foods' varied by frequency of dining out. In addition, the degree of compliance with the guidelines 'Increase activity and eat an adequate amount of foods for weight control', 'Enjoy the Korean traditional diet', and 'Control consumption of alcohol' also differed by dining out frequency in certain populations. With these results, dining out strategies were suggested for the groups with diet problems associated with dining out.

This study was to identify factors influencing drug compliance based on the subjects' interview regarding community pharmacy utilization for 2 weeks, in 2005 KNHANES. Good compliance was regarded as important factors in improving the effectiveness and minimizing adverse drug reaction, resulting in reducing the medical costs. 83% of total 11,208 pharmacy visits in 7,066 subjects showed good compliance. Good satisfaction for pharmacist's medication counseling (OR=2.23, 95% CI 1.92-2.58), higher out-of-pocket money (OR=1.32, 95% CI 1.14-1.54), and users of prescription drugs than non-prescription (OR=2.21, 95% CI 1.91-2.57) drugs were significant factors for better compliance. Disease of nervous system and mental and behavioral disorders showed lower drug compliance.

The purpose of the present study was to evaluate the characteristics of nutrient intakes of adults aged 20-64 years in Daegu and Gyeongbuk areas in comparison with Seoul and the whole nation. Data from the 1st (1998) to 3rd (2005) Korean National Health and Nutrition Examination Survey (KNHANES) were used. Total numbers of subjects were 296-369 from Daegu and 307-447 from Gyeongbuk while 1076-1244 from Seoul and 5436-6852 from the whole nation. Average energy intakes (men; 2,386, 2,581, 2,305 Kcal, women; 1,937, 1,981, 1,804 Kcal in 1998, 2001, 2005, respectively) of the subjects from Daegu were higher than those from Gyeongbuk (men; 2309, 2267, 2487 Kcal, women; 1,851, 1,845, 1,901 Kcal) and those from Seoul in 1998 and 2001 but not different from those in 2005. Energy from carbohydrate was consistently higher in the subjects from Daegu and Gyeongbuk than in those from Seoul from 1998 to 2005, when the subjects whose carbohydrate energy was over 70% comprised 34 to 58% of the total in the two regions. In 2005, the average intakes of calcium of women and men from Daegu were 512 and 573 mg, iron, 12.8 and 16.6 mg, sodium, 4,650 and 5,951 mg, potassium, 2,585 and 3,152 mg, vitamin A, 823 and 1,038 ${\mu}$gRE, thiamin, 1.10 and 1.43 mg, riboflavin, 1.08 and 1.33 mg, and niacin. 15.4 and 19.3 mg, and vitamin C, 94 and 105 mg and these intakes were not very different from those from Gyeongbuk except higher sodium intake of the Gyeongbuk subjects. Nutrients of which the intakes were over 50% lower than EAR were calcium and riboflavin and those about 30% lower than EAR were iron in women, vitamins A and C in men and women from Daegu and Gyeongbuk. From the present results, it is concluded that high dependence on carbohydrate as energy source and low calcium intake in adults of Daegu and Gyeongbuk are serious and that low intakes of riboflavin, iron and vitamins A and C need to be improved. But changes in the intakes of total energy and other micronutrients from 1998 to 2005 were not reliable enough to judge the regional nutrition due to large variations during this period. The present study also provides the adults' nutrient intakes separated by sex and age groups in the three regions which could be readily used for setting up the nutrition policy for the adults in the regions.

Objective: The purpose of this study was to analysis the determinants and trend of suicidal ideation the elderly in Korea. Methods: This study participants were selected the elderly over the age of 55 from the Korea National Health and Nutrition Examination Survey in 2001(n=1,122), 2005(n=2,098), and 2010(n=2,402). Statistical analysis methods used in this study were $x^2$-test, logistic regression analysis and other basic statistics such frequency, percentage using SPSS version 21.0. Results: In 2001, the influencing factors of suicidal ideation was spouses, subjective health status and stress recognition. In 2005, the influencing factors of suicidal ideation were spouses, subjective health status, chronic disease amount, activity limitation, depression experience and stress recognition. In 2010, the influencing factors of suicidal ideation were elderly, education level, subjective health status, activity limitation, depression experience and stress recognition. Conclusions: The health education considering the characteristics of each elderly group should be developed and applied to prevent adults' suicidal ideation because the factors influencing suicidal ideation were revealed differently between the elderly group.

The purpose of this study was to examine the association between resting heart rate (RHR) and the prevalence of colorectal cancer in Korean adults. A cross sectional analysis was performed using the Korea National Health and Nutrition Examination Survey (2005 to 2014). Total number of subjects were 10,564 adults aged over 19 years. The results showed that individuals in the highest quartile of RHR had a significantly higher prevalence of colorectal cancer (Odds ratio (OR) 2.27, 95% confidence interval (CI): 1.34-3.85 to OR 3.00, 95%CI: 1.30-6.92) compared to those in the lowest quartile. Futhermore, every 10 beat per minutes (bpm) increase in RHR was associated with 27% (95%CI: 1.03-1.58) increased prevalence of colorectal cancer. In addition, after stratification by age and gender, the result showed that older people (>65 years) in the highest quartile of RHR had a significantly higher prevalence of colorectal cancer compared to those who were in the lowest quartile of RHR. (male OR 3.19, 95%CI: 1.10-9.24 to OR 3.38, 95%CI: 1.18-9.73; female OR 2.90, 95%CI: 1.13-7.42 to OR 5.59, 95%CI: 1.20-25.99). In this study, we examined the feasibility of RHR as a predictive factor of colorectal cancer prevalence. Moreover, we found that RHR was closely related to the prevalence of colorectal cancer in the age of over 65 years.
