Exploring the customer perceived value of online grocery shopping: a cross-sectional study of Korean and Chinese consumers using Means-End Chain theory: Xinyu Jiang, Hyo Bin Im, Min A Lee; Korean J Community Nutr 2024;29(4):318-335. Published online August 31, 2024; DOI: https://doi.org/10.5720/kjcn.2024.00007

Abstract PDF PubReader ePub: Objectives
Despite the growing market share of online grocery shopping, there is a need to understand customer perceived value due to the ongoing advancements in information technology. This study explores the connections between attributes, consequences, and values. Additionally, it conducts a cross-country comparison of consumers’ online grocery shopping behaviors to gain a deeper understanding of consumer market segments and any potential variations among them.
Methods
Data was collected through an online questionnaire survey conducted from May 1 to 15, 2024, targeting 400 consumers in Seoul, Korea, and Shanghai, China, who have experience with online grocery shopping. The survey utilized the Means-End Chain theory and association pattern technique hard laddering. Data collation and analysis were conducted using the IBM SPSS Statistics 28.0 program. The LadderUX software was employed to analyze the links between attributes, consequences, and values and create the consumer purchasing process’s implication matrix and hierarchical value map (HVM).
Results
The study identified key attributes that influence online grocery shopping decisions, including delivery service, price, freshness, and quality. Korean consumers demonstrated a higher sensitivity to price (19.0%) and delivery service (17.0%). In contrast, Chinese consumers prioritized delivery service (15.0%) and after-sales service (14.8%). Commonly cited consequences included time saving (12.6% for Koreans, 11.3% for Chinese), whereas prevalent values encompassed convenience (36.8% for Koreans, 19.6% for Chinese) and economic value (26.6% for Koreans, 14.7% for Chinese). The HVM underscored these insights, highlighting diverse consumer preferences and country-specific nuances.
Conclusions
The findings highlight the current state of online food consumption and consumers’ value systems, revealing variations among countries. These findings offer empirical insights that can be used to create customized global marketing strategies that resonate with various consumer preferences and market dynamics.

Nutritional status of Daejeon citizens and needs of community nutrition care services: a cross-sectional study: Dahye Lee, Minsun Jeon; Korean J Community Nutr 2023;28(1):11-23. Published online February 28, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.1.11

Abstract PDF: Objectives
This study aimed to determine the nutritional status of residents, to examine the perception and needs of community nutrition care service, and to compare and analyze the results of females and males living in Daejeon, Korea.
Methods
The subjects were 592 adults and elderly (278 men and 314 women) residents of Daejeon. The dietary quality was assessed using the nutrition quotient (NQ), and data of the perception and needs for community nutrition care service were obtained by a questionnaire survey. Descriptive analysis was applied to analyze the demographic characteristics, perception and needs of the respondents, and independent t-test and chi-square test were performed to analyze and compare the differences between female and male participants.
Results
A nutritional status that required monitoring was established in 78.9% of the respondents in this study. The balance factor (29.1 points) was much lower than the national average. In the diversity factor, the NQ score of the female group was 47.6 points, which was 8 points lower than that of males; the NQ grade was 43.9%, showing a significant difference between females and males (P < 0.001). The respondents answered that those who needed community nutrition care services were residents experiencing health care difficulties. Additionally, dietitians (35.6%) were pointed out as the most suitable service providers. The most important factor of community nutrition care service operation was securing the budget (47.0%).
Conclusions
The results of the present study show that Daejeon residents need overall nutrition support, and a demand for community nutrition care services exists. Our findings provide basic data and can serve as a foundation for the development and establishment of a community nutrition care service model.

Foodservice Status and Perception regarding Foodservice Management in Kindergartens attached to Elementary Schools in Seoul: Ranmi Jung, Gun-Hee Kim, Jieun Oh, Sunny Ham, Seungmin Lee; Korean J Community Nutr 2022;27(6):492-502. Published online December 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.6.492

Abstract PDF

Objectives
This study examines the foodservice status of kindergartens attached to elementary schools in Seoul. We further determine the perception of elementary school principals and kindergarten assistant principals on the foodservice management for kindergartens.
Methods
This survey was conducted from July 17 to 23, 2019, enrolling 207 kindergartens attached to elementary schools in Seoul. Questionnaires were sent to principals of elementary schools and assistant principals of kindergartens, and the data obtained from 89 kindergartens were included in the analysis. The questionnaire consisted of four parts: general information on subjects, foodservice management status, foodservice management status during elementary school vacations, and the perception of principals of elementary schools and assistant principals of kindergartens on foodservice management. Data are presented as frequency and percentage or mean and standard deviation. Statistical comparison between principals of elementary schools and assistant principals of kindergartens was conducted by paired t-test, chi-square test, and Pearson's correlation analysis.
Results
A separate menu (10.1%) or recipe (20.2%) that considers preschooler characteristics was rarely used for foodservice at kindergartens attached to elementary schools. Most kindergartens did not have a separate dining space (3.4%) or a dedicated cook (93.3%). Although most kindergartens (92.1%) had operational foodservice during elementary school vacations, non-professional staff and non-nutrition teacher were mainly in charge of organizing the menu and purchasing ingredients (34.1% and 41.5%, respectively). The rate of using a contract catering company (28.0%, 23.2%) was also high. Both elementary school principals and assistant principals of kindergartens showed a high perception of the necessity for providing responsibility allowances for nutrition teachers and improving the cooking environment for kindergartens during elementary school vacations.
Conclusions
There is a need for policies and administrative support measures to improve the quality of foodservices for kindergartens attached to elementary schools.

Investigation of Millennials' Perception of Vegan Trends and Future Needs: Eun-Hye Song, Bok-Mi Jung; Korean J Community Nutr 2022;27(5):373-386. Published online October 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.5.373

Abstract PDF

Objectives
This study examined the perception of the vegan trend of millennials and their future needs.
Methods
This study was conducted online from June 21, 2021, to July 15, 2021, targeting 425 adult men and women born between 1980 and 2000. The contents of the survey were divided into four categories: general information, awareness of vegetables, awareness of vegan trends, and future needs for vegan trends.
Results
Most respondents recognized the importance of eating vegetables and perceived vegetarianism and veganism as a lifestyle. Regarding the perception of the vegan trend, the highest response rate was ‘The vegan trend is to be satisfied with my life regardless of other people’, while the lowest response rate was ‘The vegan trend is only a temporary fad’. The reasons for purchasing vegan products with high response rates were ‘interest in the earth and environment’, ‘protection of animal rights’, and ‘thinking about health’. The type of vegan product wanted in the future was delicious food, and convenience level was in the order of ‘completely cooked’, ‘half-cooked’, and ‘pre-processed’. Among the sustainable vegetarian types that millennials responded, ‘semi-vegetarian’, which can consume most animal products excluding red meat, showed the highest response rate.
Conclusions
The positive perceptions about vegetables are expected to increase. Efforts should be made to develop convenient meals using vegetables and provide reasonable prices to expand vegetable intake.

Dietary Behaviors Associated with Health Perception of Korean Adolescents from Multicultural Families: based on data from the 2017 ~ 2019 Korea Youth Risk Behavior Surveys: YueRong Hu, SuJin Song; Korean J Community Nutr 2022;27(3):192-204. Published online June 30, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.3.192

Abstract PDF

Objectives
This study examined the association between dietary behaviors and perceived health status among Korean adolescents from multicultural families.
Methods
This cross-sectional study included 2,459 Korean adolescents from multicultural families (aged 13 ~ 18 years) who participated in the 2017 ~ 2019 Korea Youth Risk Behavior Surveys. Information on the sociodemographic variables, dietary behaviors, and lifestyle variables was selfreported using a web-based questionnaire. The dietary behaviors analyzed in this study were the breakfast and food intake frequencies, including fruit, vegetable, milk, fast food, carbonated drink, sweet drink, and high caffeine/energy drinks. The adolescents’ health perception was self-rated as healthy, average, or unhealthy. The dietary behaviors associated with health perception were examined using a multiple logistic regression after adjusting for the confounding variables.
Results
In this study population, 7.6% of adolescents perceived their health status as unhealthy, and 25.4% perceived it as average. The adolescents who were girls, middle school students, and in households with a low economic status showed significantly higher percentages of poor health perception (P-values < 0.001). Skipping breakfast was significantly associated with a negative health perception. Compared to the adolescents who consumed fruits every day, those who did not consume fruits during the previous week showed a higher odd ratio (OR) for a negative health perception [OR = 2.29, 95% confidence interval (CI) = 1.32–3.97]. The adolescents who frequently consumed carbonated drinks ( 5 times/week) perceived their health status as unhealthy relative to those who did not consume carbonated drinks (OR = 2.15, 95% CI = 1.25–3.71). Skipping breakfast was significantly associated with an increased OR for a negative health perception in girls but not in boys. Compared to adolescents with a normal weight, those with overweight/ obesity (OR = 1.75, 95% CI = 1.21–2.52) and underweight (OR = 2.19, 95% CI = 1.25–3.82) showed higher ORs for negative health perception. Positive associations of overweight/obesity and underweight with negative health perception were observed in boys but not in girls.
Conclusions
Dietary behaviors and weight status were associated with the health perception in Korean adolescents from multicultural families. These findings suggest that nutrition interventions on breakfast intake and healthy food choices for this population might effectively improve their weight and perceived health status.

Sugar Reduction Perception and Sugary Food Intake among High School Students in Incheon: Gyeong-Ja Bae, Mi-Kyeong Choi; Korean J Community Nutr 2021;26(2):111-121. Published online April 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.2.111

Abstract PDF

Objectives
This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively. For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions: The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

Use of Weight-control or Health Functional Foods, Associated Weight-control Behavior and Perception among University Students in Cheongju: Gayong Kim, Munkyong Pae; Korean J Community Nutr 2021;26(1):23-36. Published online February 28, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.1.23

Abstract PDF

Objectives
This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both X² and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weightcontrol. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weightcontrol foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning ‘slightly satisfied’ and ‘slightly dissatisfied’, respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.

Customers' Perceptions of Operational Status of and Needs for Sodium Reduction in the Industry Foodservice in Seoul: Na Young Yi; Korean J Community Nutr 2020;25(1):21-31. Published online February 29, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.1.21

Abstract PDF PubReader ePub: OBJECTIVES
This study aimed to compare customers' perceptions of the need for a low-sodium diet and sodium-reduced operations in the industry foodservice by age. The relationships between health concerns and perceptions of the need for sodium-reduced operations and low-sodium diets in the industry foodservice were analyzed.
METHODS
A survey was conducted among 340 industry foodservice customers aged 20â€“50 years and residing in Seoul, Korea. This study investigated the respondents' health concerns, their perception of the need for sodium-reduced foodservice operations, their perception of a sodium-reduced diet, and the general details of the foodservices they used. A cross-tabulation analysis and ANOVA were performed to identify differences in measurement items by age, and a simple regression analysis was performed to examine relationships between measurement items.
RESULTS
For the customers' perception of the need for a sodium-reduced foodservice operation, the item â€œit is necessary to provide separate spices and sauces to reduce sodium intakeâ€ achieved the highest score (3.88 points out of a possible 5 points). For the perception of a sodium-reduced diet, the item â€œI think it is helpful for one's healthâ€ obtained the highest score (4.13 points). Respondents' health concerns had a positive effect on increasing the level of perception of the need for sodium-reduced foodservice operations and that of a sodium-reduced diet.
CONCLUSIONS
Foodservice nutritionists could help enhance their customers' perceptions of the needs for sodium-reduced foodservice operations and sodium-reduced diets by frequently providing them with sodium-related health information.

Improving Perception and Satisfaction on Middle and High School Foodservice: The Role of Student Participation Program in Serving School Meals: Jeong Eun Park, Kyung Suk Choi; Korean J Community Nutr 2018;23(3):243-256. Published online June 30, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.3.243

Abstract PDF PubReader

OBJECTIVES
We evaluated the extent to which implementation of student participation programs in serving school meals impacts student perception and satisfaction with school foodservice in middle and high school settings.
METHODS
Students' perception of management and satisfaction with quality attributes of school foodservice were assessed by questionnaire methods and compared by the program implementation status of student participation in serving school meals. Correlation and multiple regression analyses were performed to identify factors affecting perception and satisfaction.
RESULTS
The overall mean score for perception regarding the management of school foodservice was low (3.53 out of 10 points) and middle school students showed a higher mean score than high school students (4.10 vs. 2.94 points). In both middle and high schools, student perception was significantly higher in schools implementing the program. The average score for student satisfaction with the quality of school foodservice was 3.50 out of 5 points. Similarly, we observed a significantly higher satisfaction among middle versus high school students (3.93 vs. 3.04 points) and in schools implementing the program versus those that were not. Overall, student participation in serving school meals resulted in increases in satisfaction with school foodservice of 0.269 and 0.466 points among middle and high school students, respectively.
CONCLUSIONS
Implementation of student participation in serving school meals could be used as a strategy to improve perception and satisfaction of students with their school foodservice. Establishment of guidelines of student serving participation programs encompassing different perspectives from students, dietitians and school faculties are warranted.

Gender Differences in Adolescents' Dietary Perceptions and Practices: Taejung Woo, Hye Jin Lee, Kyoung Ae Lee, Seung Min Lee, Kyung Hea Lee; Korean J Community Nutr 2016;21(2):165-177. Published online April 30, 2016; DOI: https://doi.org/10.5720/kjcn.2016.21.2.165

Abstract PDF PubReader

OBJECTIVES
This study attempted to compare adolescents' dietary behaviors and perceptions by gender in order to recommend useful strategies for nutrition interventions.
METHODS
Subjects were 2,363 middle school (MS) and high school (HS) students. They completed a self-administered questionnaire on their interest in diet and health, dietary perceptions, nutrition knowledge, dietary practices, and dietary environment at home. Data were analyzed using t-test, Ï‡2-test, and simple regression analysis by gender and by school groups.
RESULTS
Overall, girls obtained higher scores than boys did for "interest" (MS: p<0.001; HS: p<0.01), "dietary perceptions" (MS: p<0.001; HS: p<0.01), and "knowledge" (MS: p<0.01; HS: p<0.001). Regarding "dietary practices," no gender differences were observed among MS students, however, among HS students, boys obtained higher scores-reflecting good practices-than girls did (p<0.01). In all subjects, dietary environment at home was strongly associated with dietary practice than other variables (MS boys: Î²=0.435, p<0.001; MS girls: Î²=0.492, p<0.001, HS boys: Î²=0.271, p<0.001; HS girls: Î²=0.429, p<0.001).
CONCLUSIONS
We observed gender differences in some of the variables such as knowledge and perception among adolescent students. Educational programs and core strategies that consider these gender differences need to be developed. Specifically, for girls, educational programs should focus on facilitating dietary recommendation adherence, whereas for boys, the program could focus on improving dietary knowledge and perceptions.

Weight Control Behaviors, Health-related Quality of Life and Nutritional Status by Overestimation of Body Image among Young Korean Females: Data from the Fifth Korea National Health and Nutrition Examination Survey, 2010-2011: Seulki Park, Taisun Hyun, Hongmie Lee; Korean J Community Nutr 2015;20(5):362-374. Published online October 31, 2015; DOI: https://doi.org/10.5720/kjcn.2015.20.5.362

Abstract PDF PubReader

OBJECTIVES
This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females.
METHODS
A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group.
RESULTS
The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group.
CONCLUSIONS
The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

Abstract PDF PubReader

OBJECTIVES
The purpose of this study is to provide the basic data for efficient operation and management of the military foodservice by analyzing the satisfaction of the quality of the foodservice and the perception of the military foodservice which are provided according to the ranks of the soldiers.
METHODS
A total of 252 military personnel (48 Private, 87 Private first class, 74 Corporal and 43 Sergeant) participated in Gyeonggi area from November 1 to 30, 2013, and data were analyzed by the SPSS Win (ver 18.0).
RESULTS
The perception with foodservice, variety of menu (p < 0.001), importance (p < 0.01), problem (p < 0.05) and leftover reason (p < 0.05) significantly differed by the rank of the soldiers. With regard to the satisfaction with food, there were significant difference by rank for all items (p < 0.01). Satisfaction with facilities did not indicate significant differences by rank. Satisfaction with sanitation indicated significant difference by rank in the categories of table ware (p < 0.05), process of distribution (p < 0.05), employee's uniform (p < 0.001) and drinking water (p < 0.05). Satisfaction with service indicated significant difference by rank with regard to kindness of employees (p < 0.01), providing information on foodservice (p < 0.05) and fast distribution (p < 0.01).
CONCLUSIONS
In order to improve the satisfaction of all ranks, there is a need to offer a variety of nutritionally balanced menu and a proper amount of food provided through the voluntary food distribution services. The results also suggested the need to find a sustainable foodservice management plan to carry out satisfaction surveys regularly in the military foodservice.

Diet-related Behaviors, Perception and Food Preferences of Multicultural Families with Vietnamese Wives: Jisun So, Sung Nim Han; Korean J Community Nutr 2012;17(5):589-602. Published online October 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.5.589

Abstract PDF PubReader

The Korean society has gone through a dramatic change in its population, with rapidly increasing number of multicultural families through international marriages since 1990s. This study investigated the differences between multicultural families and Korean families in three areas related to dietary behaviors: diet-related behaviors and perception, and food preferences. A cross-sectional analysis was performed in 500 Koreans from Korean families and 104 couples from the multicultural families with Vietnamese wives. More subjects from multicultural families grew up in the countryside, received less education and also had lower income than the subjects from Korean families. Multicultural families ate traditional Korean meals more often at home and dined out less often than Korean families. The multicultural families focused more attention on nutritional aspects of their diets than Korean families. The Vietnamese wives in multicultural families favored Vietnamese foods but they rarely ate those foods in Korea despite an easy accessibility to Vietnamese ingredients. In conclusion, the multicultural families had more traditional Korean dietary patterns than Korean families, which could have been influenced by their socioeconomic factors. Further research with a quantitative analysis is needed in future studies to understand the effect of dietary patterns on nutritional status and quality of life in multicultural and Korean families.

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. Published online October 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.5.555

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.

Survey on Present Use and Future Demand for the Convenience Food in the Elderly Group: Ji Young Park, Ji Na Kim, Wan Soo Hong, Weon Sun Shin; Korean J Community Nutr 2012;17(1):81-90. Published online February 29, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.1.81

Abstract PDF PubReader

This study is to research the use and the demand of the elderly generation that pursue economic ability and active lifestyle. The composition of the meals were "homemade meals" 65.3%, "homemade & convenience meals" 26.7% overall. For the "never miss a meal" category, 70~74 years old was 48.3%, over 80 years old was 60.0%. The elderly under 70 years old showed a high frequency in the use of alternative meals (p < 0.05) and the elderly with higher education used the alternative meals more frequently (p < 0.01). The rice-cakes, bread, tuna cans, Korean side-dishes, beverages, meat, cup-noodles and seafood as alternative meals are in the order of most frequency. Also, 96.0%, 59.0% and 46.5% of the elderly had experience in using "Ready to eat (RTE)", "Ready to heat (RTH)" and "Ready to cook (RTC)". The oldest group surveyed, the elderly at the age of 80 years old and above showed lower preference for "completely cooked state" but showed highest results in the "half-cooked state". This shows the difference between people's perception and the behavior that showed high frequency of 96.0% in the experience with "RTE". This can be inferred that the elderly needs the development of convenience food that is moderately packaged according to the newer lifestyle where the elderly live independent from their children. Moreover, there is a higher demand in the healthy convenience food, which means that there is a need for development in the quality of the convenience food that will allow more faith in convenience food by the elderly.

The Difference of Perception about Nutritional Problems and Food intakes, Nutrition Knowledge Score and Realities of Nutrition Education between Parents and Preschool Teachers: Joo Hee Lee, Eun Jung Kang, Changim Kim; Korean J Community Nutr 2011;16(6):636-646. Published online December 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.6.636

Abstract PDF PubReader

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (chi2 = 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (chi2 = 8.892, p = 0.030), fish (chi2 = 32.241, p = 0.000), beans (chi2 = 14.770, p = 0.005), vegetables (chi2 = 12.706, p = 0.013), fruits (chi2 = 14.438, p = 0.006) and milk & dairy products (chi2 = 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

A Study on the Intakes and Perceptions of Convenient Breakfast: Yeon Seo Mun, Eun Kyung Jung, Nami Joo, Ji Young Yoon; Korean J Community Nutr 2011;16(5):559-568. Published online October 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.5.559

Abstract PDF PubReader

The purpose of this study was to investigate the intakes and perceptions of convenient breakfast related to age and family type. The survey included 545 men and women living in Seoul from June to July. Questionnaire items covered their age, gender, family types, breakfast intakes and preference for convenient breakfast menu. As a result, there were significant differences in the number of breakfast intakes per week according to family types; large families recorded the highest frequency in "I have breakfast everyday" and the couple-only families and nuclear families scored relatively high numbers. In terms of the type of breakfast, the first choice was "rice and side dishes" across all the age groups (69.3%). There were differences in the preference of convenient breakfast in "bread", "cereal", "rice cake", "sunsik", and "rice gruel" by different age. The teens exhibited the highest preference of bread (5.63), and cereal (5.53) for breakfast; those who were in their fifties for rice cake (5.42). Both forties and fifties showed the higher preference of sunsik (4.58, 4.76) and rice gruel (5.89, 5.77) than other age groups. As for the preference for convenient breakfast according to family types, single person families displayed the highest preference of bread (5.42) and cereal (5.75). Couple families showed higher preference of rice gruel (5.82) than other family groups. The preference level for "rice cake" was similar among all the family types. As a result, it is suggested that the development of various breakfast menus considering age groups and family types is needed so that modern people can enjoy breakfast in terms of quality and quantity in their busy daily life.

Perception and Use of Complementary and Alternative Medicine in Diabetic Patients in Busan Area: Hyeryung Kim, Eunjoo Son, Mikyung Kim, Eunsoon Lyu; Korean J Community Nutr 2011;16(4):488-496. Published online August 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.4.488

Abstract PDF PubReader

The purpose of this study was to investigate the perception and utilization of Complementary and Alternative Medicine (CAM) for diabetic patients in Busan. The subjects were 227 patients at two general hospitals (over 400 bed). This study was performed through the interviewing process using questionnaires conducted from January to April, 2010. Of a total of subjects, 109 patients (48.0%) had taken CAM at least one time. The patients used CAM recognized that they were 'auxiliary medicines' (39.4%), 'supplementary health foods' (32.1%) and 'medicines' (19.3%), but inexperienced patients perceived them as 'supplementary health foods' (29.6%), 'unscientific treatment' (22.6%) and 'medicines' (20.2%), It was significantly different between two groups of patients (p < 0.001). The number of CAM types used for the patients was 51. The CAM types were plant foods (64.3%), dietary supplement (23.6%) and animal diets (12.1%). The patients used an average of 5.9 different kinds of CAM and an average of 3.8 years them and paid \93,345 per month. The patients with diabetic complications and for longer morbidity periods used CAM for significantly (p < 0.05) longer periods. The mean effectiveness scores of the patients used CAM were 3.31/5.00 for efficacy satisfaction, 3.58/5.00 for fewer side effects compared to those of oral drugs, 3.60/5.00 for psychological stability, 3.81/5.00 for easiness to use, and 3.06/5.00 for economic satisfaction. Of the patients that used CAM, 55.9% did not consult with doctors about CAM. More than two-thirds of the patients (77.1%) did not feel the need to consult with doctors.

Association between Risk Factors for Health and Taste Perceptions of Middle-aged and Elderly People Living in Rural Areas: Mee Sook Lee, Se In Oh, Chung Shil Kwak; Korean J Community Nutr 2011;16(1):145-154. Published online February 28, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.1.145

Abstract PDF PubReader

The purpose of this study was to evaluate the relationship between taste perceptions and risk factors for health of Korean elderly living in rural areas. Recognition thresholds for four basic tastes, drug consumption, BMI, fasting blood glucose, serum total cholesterol, serum triglyceride, systolic blood pressure, and diastolic blood pressure were assessed in 176 males and 312 females aged between 50 and 88 years. For the recognition threshold of the four basic tastes, alcohol drinking did not influence their sensitivities, but the alcohol drinking group preferred a higher pleasant concentration of NaCl than did the non-alcohol drinking group. However, smoking significantly decreased sensitivities of the four basic tastes. For the pleasant concentration of NaCl, the smoking group tended to prefer a higher concentration than the non-smoking group. Drug consumption, fasting blood glucose, serum total cholesterol, and serum triglycerides did not have a significant correlation to the sensitivity of the four basic tastes and preference of salty solution. Systolic blood pressure and diastolic blood pressure may have been positively correlated with the pleasant concentration of NaCl but did not correlate with the recognition thresholds of NaCl and sucrose. Further, systolic blood pressure was negatively correlated with the recognition thresholds of caffeine, whereas diastolic blood pressure was negatively correlated with the recognition thresholds of caffeine and citric acid. The finding that the risk factors for health correlated with taste perception has diagnostic and practical implications for health promotion for the elderly.

Monitoring of Genetically Modified Bean Sprouts at Traditional Markets in Seoul and a Survey of Perception of Traditional Market Merchants and High School Students on Genetically Modified Organisms: Seul Ki Choi, Jung Hoon Lim, Jee Seong Shin, Jin An Jeong, Hyojee Joung; Korean J Community Nutr 2010;15(5):679-686. Published online October 31, 2010

Abstract PDF: The purpose of this study is to monitor genetically modified bean sprouts at traditional markets in Seoul and to investigate perception of traditional market merchants and high school students on genetically modified organisms (GMOs). We analyzed 30 bean sprouts that were selected at 11 traditional markets in Seoul using the method of polymerase chain reaction (PCR). Also, we compared perception of GMOs between merchants (n = 30) and students (n = 126). Knowledge test about GMOs was performed by students. The result of PCR, 16.7% of bean sprouts were confirmed as GM bean sprouts (n = 5). Students had significantly more exposure to information about GMOs than merchants (p < 0.05). Major information sources about GMOs were from mass media (television, newspaper and radio). About half of subjects were not aware that they eat GMOs and GMOs are sold to consumers. Only 17.3% of subjects had constant eating intent for GMOs after perceiving foods that he/she usually eats are GMOs. 51.3% of subjects had willingness to purchase GMOs if GMOs have same quality and lower cost than natural foods. 37.2% of subjects thought that GMOs would be harmful to humans. Students had more positive perception of GMOs' side effects than merchants (p < 0.01). There was no merchant who knew labeling of GMOs. 19.1% of students knew labeling of GMOs. Students' mean percentage of correct answers of six questions about GMOs was 45.2%. Therefore, providing adequate information about GMOs is needed for consumer's choice whether to purchase GMOs or not.

Perception on Nutrition Labeling of the Processed Food among Elementary School Teachers in Busan: Jeong Sook Lee; Korean J Community Nutr 2009;14(4):430-440. Published online August 31, 2009

Abstract PDF: This study was carried out to investigate the perception on nutrition labeling of the processed foods among elementary school teachers in Busan. The survey was conducted from November 1 to November 30, 2008 by questionnaires and data which were analyzed by SPSS program. The results are summarized as follows. Ninety five point seven percent of the male teachers and 98.2% of the female teachers recognized the nutrition labeling (NL). The necessity of a NL system and comprehension of NL were higher in the female group than the male group. NL was trusted by 22.9% of male teachers and 19.7% of female teachers. The main reason for checking NL of the teachers was for food safety. For the most important NL items at purchasing the food, the teachers replied 'trans fatty acid' and 'cholesterol'. Five point seven percent of male teachers and 17.0% of female teachers were educated for NL. Seventy two point nine percent of males and 91.0% of females recognized the necessity of NL teaching. It is necessary to prepare education programs for both teachers and students about accurate recognition of NL.

Abstract PDF: This study was performed in order to compare the differences in dietary self-efficacy and eating behaviors as well as the relationship of weight control attitudes according to eating disorder perception and obesity index for high school girls majoring in dance. Almost half (45.5%) of the subjects perceived eating disorders, and the rate of underweight group was 45.7%. Forty-four percent of the group that perceived eating disorders were in modern dance, while 55.0% of the group that did not perceived eating disorders were in Korean dance (P <0.05). For the obesity index, a similar rate was shown between the different types of dance for the underweight group, but in the normal group, 54.5% were in Korean dance (P <0.05). Most (82.0%) of the group that perceived eating disorders had fears on obesity, while only 53.3% of the non-perceiving group had fears on obesity (P <0.01). Over half (58.3%) of the underweight group had fears on obesity, while 77.2% of the normal group showed fear in that (P <0.05). For necessity of weight loss to do dance performances, 25.0% of the underweight group and 57.9% of the normal group need that (P <0.05). Most of the group that perceived eating disorders (92.0%) answered that they had experience in very low calorie diets, while only 40.0% of the non-perceiving group had experience (P <0.001). For necessity of calorie education, 42.0% of the group that perceived eating disorders and only 20.0% of the non-perceiving group answered is needed (P <0.05). For eating behavior , the group that perceived eating disorders had lower total scores compared to the non-perceiving group (P <0.001), The group that perceived eating disorders showed lower scores for restraint eating (P <0.01) and emotional factors (P <0.001) except by external eating. This study showed that high school girls majoring in dance have high interest in weight control and problems with wrongful body images and eating behaviors, as well as need for calorie education were suggested. Thus, it is necessary to develop and execute a proper weight control education program for the subjects.

Evaluation of Foodservice Managers' Perception on Safety Management in Childcare Centers and Kindergartens: Hyung Soo Park, Kyung Mi Lee, Hye Rin Seol, Ki Hwan Park, Kyung Ryu; Korean J Community Nutr 2009;14(1):87-99. Published online February 28, 2009

Abstract PDF: The purpose of this study was to investigate the perception of foodservice managers in childcare centers and kindergartens for identifying the vulnerable areas of safety management. The foodservice managers in 1,144 of nationwide childcare centers and kindergartens were surveyed from May to October 2007 to answer a total 72 questions in areas of general characteristics, actual practice of foodservice management and safety management perception. Meals were served in 97.7% of surveyed facilities and 91.0% among them were self-operated. The hiring rate (27.8%) of dietitians in childcare centers was significantly lower than the rate (82.0%) of kindergartens. The needs of dietitian employment between childcare centers and kindergartens differed as 44.9% and 87.5%, respectively. In knowledge on food-borne illnesses, they have the wrong information in the field of season for frequent outbreak, major pathogens and foods causing food-borne illnesses. The food-borne illnesses (36.2%) were indicated as the major problem in foodservice facilities and the degree of risk exposure was considered as safe (70.1%). More than 70% of both facilities answered as sanitary in the status of personal hygiene. Only 38.0% recognized the Facility and Equipment Standard in the Childcare Law and Early Childhood Education Law. In preparation of meals and management of cooking processes, kindergarten scored significantly high compared to childcare centers (p < 0.05 or p < 0.01) while the necessity of standards was not different in both facilities. Among managers surveyed, 28.8% had taken food safety education from professional institutions and more than 80% in both facilities indicated the need of professional educations. These results suggest that it is necessary for the systematic sanitary education of foodservice managers by developing the sanitary management standard as well as the amendment of laws related foodservice in childcare centers and kindergartens.

A Comparison Study on Perception of Body Image and Dietary Habits of High School Students between Urban and Rural Areas: You Kyung Kim, Weon Sun Shin; Korean J Community Nutr 2008;13(2):153-163. Published online April 30, 2008

Abstract PDF: The objective of this research was to study the differences between urban and rural areas high school students in body image and dietary habits. The number of subjects in Seoul and Kyungkido were 902. Based on self-reported height and weight, there was no significant difference between the urban and rural students. However, the rate of obesity was significantly higher in males, whereas the rate of underweight was significantly higher in females, especially for urban females (p < 0.05). Their ideal body image ratio as skinny or slender-type was 91.6% (urban) and 95.7% (rural) for male category while 100% (urban) and 99.4% (rural) for females. Urban females had a strong preference for a skinny body (p < 0.05). Rural students were more highly interested in weight control than urban students were, but they appeared not to care their health. In addition, they had significantly lower levels of weight control knowledge and dietary attitude score (p < 0.001). Subjective assessment of body weight appeared to be more important in terms of body satisfaction, weight control knowledge and dietary attitude than actual measurement of body mass index. Significant test revealed that weight control knowledge was related to dietary attitude (p < 0.01). (p < 0.01).

Weight-related Perceptions, Practices and Eating Behaviors of Middle School Students: Associations with BMI: Ji Eun Kim, Hye Sun Min; Korean J Community Nutr 2008;13(1):13-23. Published online February 29, 2008

Abstract PDF: This study investigated the association between the weight status of middle school students and the various weightrelated characteristics including desired weight, weight perception, weight-related practice, physical activity, and overeating behavior. Questionnaires were administered to 473 middle school students (178 boys and 295 girls) in Daejeon. Boys and girls were divided into three groups respectively; (1) underweight (BMI < 5th percentile) (2)normal weight (5th percentile < or = BMI < 85th percentile) (3) overweight (BMI > or = 85th percentile). Using BMI calculated from measured height and weight, 14.0% of boys and 6.8% of girls were underweight, and 16.3% of boys and 14.2% of girls were overweight. However, among this sample of students, 38.4% of boys and 13.6% of girls perceived themselves as underweight and 29.4% of boys and 44.9% of girls perceived themselves as overweight. We found that overweight students reported their body weights lower and their heights higher compared to nonoverweight students, resulting in an underestimation of BMI. Based on desired BMI, 79.9% of the girls desired to be underweight and 73.0% of the boys desired to be normal weight. Overweight or normal weight students were less satisfied with their body weights than underweight students. Girls had more weight control experience and concern compared to boys. Overweight girls spent longer times in watching TV compared to non-overweight girls (p < 0.001) and had more overeating behaviors (p < 0.05). Overweight students reported that they ate snacks less frequently than non-overweight students, which may be due to their tendency to report less eating. In conclusion, significant gender differences and weight status differences existed in weight perception, weight satisfaction, and weight control experience and concern. Because perception of overweight is likely to lead to unhealthy eating behaviors and weight control, efforts for adolescents to improve accuracy of weight perceptions and to understand the benefits of being healthier are needed.

Personal Maternal Body Image Perceptions Their Preschool Children: Wha Jin Hyun, Yi Joung Hong; Korean J Community Nutr 2005;10(6):930-942. Published online December 31, 2005

Abstract PDF: This study was performed to investigate body image perceptions of women about themselves and their preschool children and also to investigate the relationship between these perceptions. Subjects were 545 women and their children (279 boys and 268 girls) residing in Daejeon city. 67.7% of women were classified as normal group, 18.6% as overweight group, and 13.8% as underweight group by BMI. 68.5% and 78.7% of their boys and girls, respectively, were classified as normal group, 22.4% and 16.4% as overweight group, 9.1% and 4.9% as underweight group by WLI. Women made relatively accurate judgments on their current body sizes and selected their body images as the most desirable one. But they preferred plumper figures for their children and failed to perceive their overweight children as overweight. While 74.7% of women wished to be thinner, 81.1% of them wished their children to be fatter. Women spending less then 100 thousand won and more than 500 thousand won as monthly food expenses and having only one child perceived their children's current body sizes the lowest and the highest, respectively. Women wished boys to be fatter than girls. Their current body sizes were correlated positively with the children's current body size (p<.01), and their healthiest, attractive, and 'wish' figures were correlated positively with children's current, healthiest, attractive, and 'wish' figures (p<.05 - p<.01). Body size dissatisfaction (wish to be thinner) and BMI of women were correlated negatively with children's healthiest and attractive figures (p<.01). These findings suggest that in order to correct the women's body image misperceptions and to prevent childhood obesity, mother's perception about healthy body images for themselves and their children need to be included in nutrition education. Also, it is necessary to assist mothers to understand the relationship of body size and weight status with the risk of chronic disease which might appear later in their children's life.

A Study on Middle School Students' Recognition of Food and Nutrition Part in Home Economics: Sun Jeong Choi, Hee Sook Sohn, Youn Soo Cha, Sook Bae Kim; Korean J Community Nutr 2004;9(1):12-18. Published online February 29, 2004

Abstract PDF: The purpose of this study was to investigate the differences of middle school students' recognition of food and nutrition part in Home Economics by gender, school location and school type. The study was carried out through questionnaire about three category: perception (interests, practical usefulness, attitude change in food behavior), difficulty (nutrition and health in adolescence, balanced diet, principle of cooking and preparing food), necessity (nutrition and health in adolescence, balanced diet, principle of cooking and preparing food). The subjects were 1014 middle school students of 1st grade in Jeonbuk area; urban 334, suburban 339 and rural 341. The results of this study were as follows. 1) There was difference in 'interests' by gender (girls > boys), school location (urban, suburban > rural) and school type (coeducation > boys, girls). There were differences in 'practical usefulness' by school location (urban > rural) and in 'attitude change in food behavior' by school location (urban > suburban > rural) and school type (boys, girls > coeducation). 2) There was difference in difficulty in section of 'nutrition and health in adolescence' by school location (suburban > rural). There were no differences in section of 'balanced diet' by gender, school location and school type. But there were differences in section of 'principle of cooking and preparing food' by school location (urban, rural > suburban)and school type (coeducation > boys). 3) There were differences in necessity for 'balanced diet' and for 'principle of cooking and preparing food' by school location (urban, suburban > rural) and school type (coeducation > boys, girls). Characteristically, the boys had more necessity for 'nutrition and health in adolescence' and for 'balanced diet' than girls but girls had more necessity for 'principle of cooking and preparing food' than boys. It suggests that gender, school type and school location should be considered for an effective and practical curriculum of food and nutrition part in Home Economics.

The Dietary Behavior of Obese and Normal Weight Elementary School Children with Maternal Guidance for Their Dietary Behavior: Hye Sang Lee, Woon Seon Jeong, Ung Im Park; Korean J Community Nutr 2003;8(6):831-839. Published online December 31, 2003

Abstract PDF: This study was conducted to investigate whether there were any differences in the body image perception, dietary behavior and maternal dietary guidance between an obese group ("OG") and a normal weight group ("NWG"), and furthermore, to provide basic informations for comprehensive educational programs for obese children. For this purpose, the questionnaire method was used. The subjects were 1,501 elementary school children, in the 4th to the 6th grades in Seoul, Busan, Daegu, Gwangju, and Andong, and their mothers (1,459). The percentage of the children who misperceive their body image was higher among the girls (30.4%) than the boys (22.6%). The average scores for balanced dietary behavior as assessed by the children was higher in the OG than in NWG; the average scores for dietary control as assessed by their mothers was higher in the NWG than in the OG. The scores for dietary behavior as assessed by the children was different from those as assessed by their mothers. Assuming that the mothers would give more correct and balanced answers, the development of a reliable questionnaire for dietary behavior that could be more accurately answered by the children is necessary. Maternal dietary guidance for dietary control was more frequently given in the OG as compared with the NWG and more frequently in girls as compared with boys ; while that for balanced diet was more in the NWG as compared with the OG. The worse the mothers estimate of the dietary behavior for their children, the more they tried to guide their children in dietary behavior. It is recommended that the children should be taught to correctly recognize the degree of their obesity, and receive the appropriate educational program accordingly, including the maternal dietary guidance.

Nutrient Intake of the Rural Elderly Living in Kyungnam -Focusing on Health and Aging Status, and Life-Satisfaction: Kyung Hae Lee, Mi Young Park; Korean J Community Nutr 2001;6(5):773-788. Published online December 31, 2001

Abstract PDF: The purpose of this study was to investigate the difference in nutrient intake according to the level of self-perception of health status, aging status and life satisfaction of the rural elderly. The factors for the study were surveyed by interview method. The subjects were 270 people(71 male, 129 female) aged over 65 years(73.5 +/- 5.6ys) in the Ham-an area. The obtained results as follows : By evaluation of self-perception of health status, 57.5% of subjects answered they are in a bad health condition. The 91.5% of subjects had diseases(rheumatitis & arthritis 31.4%, cardiovascular disease 20.2%, gastric disease 10.2%). The women had more diseases than the men(p<0.01). The subjects took medical treatment in private hospital(40.5%) and public health centers(35.0%). The men showed better level of aging status(p<0.001) and life satisfaction index(p<0.01) than the worsen. Living with spouse influenced the aging status(p<0.05) and the more pocket money influenced life satisfaction(p<0.05) and aging status(p<0.05). The elderly who eat regularly 3 times a day(p<0.05) and have a good appetite(p<0.001) appeared to have positive effect on the self perception of health status and aging status. An increasing level of the self-perception of health status and regular exercise worked to improve aging status(p<0.001). The habits of smoking and alcohol drinking, however had no effect on any index. The self-perception of health status affected the nutrient intake, but only in female elderly. The aging status and the life satisfaction index related overall positively to the intake of nutrients. In conclusion, the study shows that gender did influence nutrient intake in the elderly. The women who live alone rated lowest in social resources and health condition therefore their nutrient intake was also extremely in deficit. For successful aging, a program for rural elderly is needed, i.e. actions to provide minimum economic life, food delivery and psychological/physical health care through regional public health centers.
