Abstract PDF PubReader ePub: Objectives
This study was conducted to evaluate the effects of a nutrition education program on metabolic syndrome in middle-aged Korean adults.
Methods
A total of 411 Korean adults 30–59 years of age were allocated randomly into three groups: the nutrition education group for promoting Han-sik consumption (HG), the nutrition education group for eating balanced diet (EG), and the control group (CG). The HG and EG received four face-to-face nutrition education sessions over 16 weeks to improve nutritional problems based on the individual’ usual diet. Effectiveness of the program was evaluated with the differences of self-reported dietary behaviors, dietary intakes, anthropometric measurements and biochemical indices between the baseline and the end of the nutrition education program. The changes within groups were analyzed using paired t-test and McNemar test and effectiveness among three groups was analyzed by repeated analysis of variance.
Results
After the nutrition education, the percentages of participants who achieved the recommended food group consumption in the Korean Food Guidance Systems significantly increased in HG (P = 0.022). Body weight (P = 0.007), body mass index (P = 0.002), and triglycerides (P = 0.002) significantly decreased in HG. Waist circumference and diastolic blood pressure decreased in all three groups (P < 0.05).
Conclusions
This study found that tailored nutrition education program for middle aged Korean adults showed beneficial effects on improving dietary behaviors and metabolic syndrome risk factors. Further studies are needed to assess the long-term effects of the nutrition education programs on metabolic syndrome risks.

Use of Dietary Supplements and Determinants of Taking Dietary Supplements by Gender in the Korean Population: Using the 4(th) Korean National Health and Nutrition Examination Survey (2007-2009): Yun Jung Lee, Minji Kang, Hee Young Paik, YoonJu Song; Korean J Community Nutr 2017;22(4):347-355.

OBJECTIVES
Although dietary supplements use in Korea has been rapidly increasing and women are more likely to take dietary supplements more than men, only a few studies have been conducted to investigate factors contributing to gender differences in dietary supplement use in the Korean population. The aim of this study is to evaluate the prevalence of dietary supplement use and also identify gender-specific key factors that contribute to it using the data of the 4th KNHANES.
METHODS
Subjects were divided into user and non-user groups according to the answer given to the question that asked whether they had used any dietary supplement for more than 2 weeks on a regular basis during the previous year. Factors related to dietary supplement use were examined by general characteristics, health behavior and eating behavior.
RESULTS
Prevalence of dietary supplement use was 13.6% for men and 20.6% for women. Users were more likely to be middle-aged, have higher income and education, have a spouse, or reside in dong areas in both men and women. Regarding health behaviors, men with desirable lifestyle behavior were more likely to take dietary supplements, while men who smoked were less likely to take dietary supplements. Regarding disease history, both men and women with a current disease had higher odds of taking supplements. With regard to dietary behavior, frequent eating out and nutrition attitude were associated with higher odds of taking supplements in both men and in women.
CONCLUSIONS
Health or dietary behavior related factors that were associated with taking supplements differed by gender. These findings can be useful for planning gender-specific dietary education and health programs.

A Study on the Perception as HANSIK (Korean Food) for the Common Dishes in Korean Adults Residing in Seoul and Metropolitan Area: Young Hee Park, Minji Kang, Hyun Wook Baik, Sang Woo Oh, Su Jin Park, Hee Young Paik, Jeong Sook Choe, Jin Young Lee, Min Sook Kang, Hyojee Joung; Korean J Community Nutr 2012;17(5):555-578.

Abstract PDF PubReader

This study was conducted to investigate which food items are perceived as HANSIK (Korean food) in Korea. 562 males and females aged 20-70 were surveyed on 512 most frequently consumed dish items from 4th Korean National Health and Nutrition Survey if they perceive it as HANSIK. Dish items in kimchi, namul - sukchae (cooked and seasoned vegetable) and jeotgal (salt-fermented food) category showed high response rate to be perceived as HANSIK. The response rate of twigim (frying foods) as HANSIK was low showing less than 70%. The response rate as HANSIK for foreign origin foods such as ramen and jjajangmyeon (black bean paste noodle) were lower than 25%. In jang . yangnyum (seasoning) category, doenjang (soybean paste) and gochujang (red pepper paste) showed high response rate as HANSIK more than 90%. Females showed a higher response rate as HANSIK than males for most food items except several items of myen . mandu (noodle and dumpling). The younger age group had higher HANSIK perception on many items of recently consumed foods, especially budae-jjigae (spicy sausage stew) (p < 0.001) and jwipo-jorim (braised dried filefish) (p < 0.001), implying that they already accept the common foods as HANSIK regardless of the origin. These results provide an information on the foods perceived as HANSIK among currently consumed common foods in Korea and these results can be utilized for establishment of HANSIK concept reflecting transition of dietary life in Korea.

A Comparison of Cluster and Factor Analysis to Derive Dietary Patterns in Korean Adults Using Data from the 2005 Korea National Health and Nutrition Examination Survey: Yoon Ju Song, Hee Young Paik, Hyojee Joung; Korean J Community Nutr 2009;14(6):722-733. Published online December 31, 2009

Abstract PDF: The purpose of this study was to explore dietary patterns and compare dietary patterns using cluster and factor analysis in Korean adults. This study analyzed data of 4,182 adult populations who aged 30 and more and had all of socio-demographic, anthropometric, and dietary data from 2005 Korean Health and Nutrition Examination Survey. Socio-demographic data was assessed by questionnaire and dietary data from 24-hour recall method was used. For cluster analysis, the percent of energy intake from each food group was used and 4 patterns were identified: "traditional", "bread, fruit & vegetable, milk", "noodle & egg", and "meat, fish, alcohol". The "traditional" pattern group was more likely to be old, less educated, living in a rural area and had higher percentage of energy intake from carbohydrates than other pattern groups. "Meat, fish, alcohol" group was more likely to be male and higher percentage of energy intake from fat. For factor analysis, mean amount of each food group was used and also 4 patterns were identified; "traditional", "modified", "bread, fruit, milk", and "noodle, egg, mushroom". People who showed higher factor score of "traditional" pattern were more likely to be elderly, less educated, and living in a rural area and higher proportion of energy intake from carbohydrates. In conclusion, three dietary patterns defined by cluster and factor analysis separately were similar and all dietary patterns were affected by socio-demographic factors and nutrient profile.

Analysis of Dietary Factors of Chronic Disease Using a Neural Network: Sim Yeol Lee, Hee Young Paik, Song Min Yoo; Korean J Community Nutr 1999;4(3):421-430. Published online September 30, 1999

Abstract PDF: A neural network system was applied in order to analyze the nutritional and other factors influencing chronic diseases. Five different nutrition evaluation methods including SD Score, %RDA, NAR INQ and %RDA-SD Score were utilized to facilitate nutrient data for the system. Observing top three chronic disease prediction ratio, WHR using SD Score was the most frequently quoted factor revealing the highest predication rate as 62.0%. Other high prediction rates using other data processing methods are as follows. Prediction rate with %RDA, NAR, INQ and %RDA-SD Score were 58.5%(diabetes), 53.5%(hyperlipidemia), 51.6%(diabetes), and 58.0%(diabetes)respectively. Higher prediction rate was observed using either NAR or INQ for obesity as 51.7% and 50.9% compared to the previous result using SD Score. After reviewing appearance rate for all chronic disease and for various data processing method used, it was found that iron and vitamin C were the most frequently cited factors resulting in high prediction rate.
