Can Dining Alone Lead to Healthier Menu Item Decisions than Dining with Others? The Roles of Consumption Orientation and Menu Nutrition Information: EunSol Her, Carl Behnke, Barbara Almanza; Korean J Community Nutr 2021;26(3):155-166. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.155

Abstract PDF: Objectives
Driven by a growth of single-person households and individualized lifestyles, solo dining in restaurants is an increasingly recognizable trend. However, a research gap exists in the comparison of solo and group diners’ menu-decision making processes. Based on the self-control dilemma and the temporal construal theory as a theoretical framework, this study compared the ordering intentions of solo vs. group diners with healthy vs. indulgent (less healthy) entrées. The mediating role of consumption orientation and the moderating role of amount of menu nutrition information were further explored to understand the mechanism and a boundary condition.
Methods
A scenario-based online survey was developed using a 2 (dining social context: solo vs. with others) × 3 (amount of menu nutrition information: no nutrition information vs. calories vs. calories/fat/sodium), between-subjects, experimental design. Consumers’ level of nutrition involvement was controlled. A nationwide survey data (n = 224) were collected from a crowdsourcing platform in the U.S. Data were analyzed using multivariate analysis of covariance, independent t-test, univariate analysis of covariance, and moderated mediation analyses.
Results
Findings reveal that solo (vs. group) diners have less (vs. more) intentions to order indulgent menu items due to a more utilitarian (vs. more hedonic) consumption orientation in restaurant dining. Findings also show that solo (vs. group) diners have more (vs. less) intentions to order healthy menu items when the restaurant menu presented nutrition information including calories, fat, and sodium.
Conclusions
The findings contribute to the literature of foodservice management, healthy eating, and consumer behavior by revealing a mechanism and an external stimuli of solo vs. group diners’ healthy menu-decision making process in restaurants. Furthermore, the findings provide restauranteurs and health professionals with insights into the positive and negative impacts of menu nutrition labelling on consumers’ menu-decisions.

Awareness and Practice of Sugar Reduction in School Foodservice and the Practice of Nutrition Education in Daegu: Suhyang Jang, Kilye Kim, Yeon-Kyung Lee; Korean J Community Nutr 2021;26(3):167-176. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.167

Objectives
This study was conducted to identify the awareness and practice of reducing sugar in school meals and the status of nutrition education regarding sugar reduction.
Methods
An online survey was conducted on 101 nutrition teachers (dietitians) working at elementary, middle, and high schools in Daegu.
Results
School nutrition teachers in Daegu recognized the need for efforts to reduce the sugar intake in the Korean diet, and it was found that elementary nutrition teachers were more aware of the implementation of the sugar reduction policy at the national level than middle and high school nutrition teachers (P = 0.002). Among the policies to reduce sugar intake at the national level, there was a high need for the promotion of self-control and limiting the sales of food with high sugar content in schools and their vicinity. The degree of practice for reducing sugar in school meals was found to be higher in the preparation, purchase, and cooking stage compared to the serving stage (P < 0.05). There was a high need for changing the preferences of the subjects for a sweet taste as a means of reducing the sugar in school meals. Thirty-six percent of nutrition teachers conducted sugar reduction education, and sending out school newsletters was the highest type of nutrition education at 80.6%.
Conclusions
To effectively promote reduced sugar intake in school meals, it is necessary to change the preference of the subjects for sweetness and to conduct continuous education that can improve the awareness of people for reducing their sugar intake. For this, it is necessary to set aside time for nutrition education and to prepare an institutional framework for providing this education.

Do American Consumers Perceive Corporate Social Responsibility Actions and Exhibit Loyalty Intentions Differently according to the Reputation of Fast Food Restaurants?: Kiwon Lee, Youngmi Lee; Korean J Community Nutr 2021;26(3):177-187. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.177

Abstract PDF: Objectives
This study investigated the different perceptions of customers toward traditional and non-traditional fast-food restaurants regarding restaurant healthfulness, corporate reputation, and the impact of corporate reputation on loyalty intentions through corporate social responsibility (CSR) motive.
Methods
An online survey was conducted on U.S. residents who were aware of fast food restaurants’ CSR activities. Participants selected one fast food restaurant participating in CSR activities, coded as either traditional (n = 117) or non-traditional (n = 48), and answered questions about the selected restaurant’s healthfulness, reputation, CSR motives, and loyalty intentions. The participants’ perceptions of healthfulness and corporate reputation of the two types of fast-food restaurants were compared. A mediation path of corporate reputation – CSR motive – loyalty intention was analyzed.
Results
Non-traditional fast-food restaurants (5.02 ± 1.26) were perceived to be more healthful than traditional ones (3.93 ± 1.72). The participants perceived that compared to traditional fastfood restaurants, non-traditional ones had a better overall corporate reputation (P = 0.037), were more concerned about their customers (P = 0.029), better workplaces (P = 0.007), more environmentally and socially responsible (P < 0.001), and offered higher quality products and services (P = 0.042). Significant positive correlations were shown between restaurant healthfulness and corporate reputation (P < 0.001 for all reputation items). The suggested mediation path was supported with 95% CIs excluding zero, implying that when fast-food restaurants had a better reputation overall, were customer oriented, good employers, strong companies with a good product and service quality, social and environmental responsibility, the participants were more likely to perceive their CSR activities to be sincere and were hence loyal to that restaurant.
Conclusions
Overall, participants were more favorable towards non-traditional fast-food restaurants which had a healthier image and better reputation than traditional ones. Therefore, fast food restaurants need to consider offering healthy food and enhance their image, which would maximize the return on their investment in CSR.

Analysis of Surveys to Determine the Real Prices of Ingredients used in School Foodservice: Seo-Hyun Lee, Min A Lee, Jae-Yoon Ryoo, Sanghyo Kim, Soo-Youn Kim, Hojin Lee; Korean J Community Nutr 2021;26(3):188-199. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.188

Abstract PDF: Objectives
The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice.
Methods
A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis.
Results
The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education.
Conclusions
Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.

Analysis of Awareness, Knowledge, and Behavior about Food Hygiene·Safety Among the elderly: Mi Sook Lee, Sim-Yeol Lee; Korean J Community Nutr 2021;26(3):200-210. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.200

Abstract PDF: Objectives
This study was conducted to investigate the awareness, knowledge, and behavior about food hygiene·safety among the elderly, and to provide basic data on this for their healthy dietary life.
Methods
The study was conducted through a survey using a self-administered questionnaire on 473 elderly people over 60 years old living in Seoul and Gyeonggido. The questionnaire was designed to examine general characteristics, meal preparation status, the relation between awareness, knowledge, food hygiene behavior, and safety.
Results
Among the particpants, 44.2% of the total people surveyed were elderly married couples, and 14.0% were single-person households. For men, most of the meals were prepared by the spouse (74.1%), and among women, 93.8% prepared their meals themselves (P < 0.001). 61.3% of the total subjects answered that they were very interested in food hygiene and safety. Men (32.4%) thought it was more difficult to collect food hygiene·safety information compared to women (14.0%, P < 0.001). The knowledge score about food hygiene·safety was 0.60 (P < 0.05) and the behavior score was 3.70 (P < 0.001). The correlation coefficient between knowledge and behavior according to food hygiene·safety was 0.371 (P < 0.001).
Conclusions
The food hygiene·safety behavior of the elderly was associated with knowledge (P < 0.001). Therefore, food hygiene·safety education is necessary to ensure information availability and promote the health of the elderly.

Association between Relative Preference for Vegetables and Meat and Cancer Incidence in Korean Adults: A Nationwide Population-based Retrospective Cohort Study: Ga-Eun Yie, An Na Kim, Hyun Jeong Cho, Minji Kang, Sungji Moon, Inah Kim, Kwang-Pil Ko, Jung Eun Lee, Sue K. Park; Korean J Community Nutr 2021;26(3):211-227. Published online June 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.3.211

Abstract PDF: Objectives
We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea.
Methods
We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sexspecific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level.
Results
During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women.
Conclusions
Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.
