Problems Encountered in Analyzing the Market Size, Purchase, and Consumption of HMR in the Republic of Korea: Sung Ok Kwon, Injoo Choi, Yoojeong Joo, Jihyun Yoon; Korean J Community Nutr 2022;27(6):480-491. Published online December 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.6.480

Objectives
This study examined the problems encountered when analyzing the market size, purchase, and consumption of HMR (home meal replacements) in the Republic of Korea.
Methods
The macro data relevant to the market size and purchase status of HMR were critically summarized. The micro data retrieved from the 2019 & 2020 Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed to understand the consumption of HMR.
Results
The Korea Agro-Fisheries & Food Trade Corporation and the Ministry of Food and Drug Administration reported the market size of HMR, whereas the Korean Rural Economic Institute and the Rural Development Administration reported the purchase expense and frequencies of HMR. Since the values on the market size and purchase status were calculated or surveyed using different scopes of HMR, there have been reliability issues for the data presented. Additionally, lack of consensus on the use of Korean terms corresponding to HMR was found to be a problem. To examine the consumption of HMR, analysis of the food intake data from KNHANES presented results with very low validity due to the inappropriate survey and coding scheme not reflecting the inclusion of new food types.
Conclusions
Several problematic discrepancies were encountered in the statistics on HMR. The fundamental cause of these problems was the absence of agreement on the scope of HMR and the Korean terms corresponding to it. Considering the increasing importance of HMR in Korean diets, urgent cooperative efforts are required between the government and academia to derive an agreed Korean term and establish the scope of HMR.

Dietary Life of Chinese International Students according to the Frequency of University Foodservice Use in Korea: Yan Cui, Hye-Jong Yoo, Injoo Choi, Jihyun Yoon; Korean J Community Nutr 2020;25(4):291-302. Published online August 31, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.4.291

Abstract PDF

Objective
This study investigated the current use of university foodservice among Chinese international students in Korea, focusing on the relationship between the frequency of university foodservice use and their dietary life.
Methods
An online survey was conducted on 452 Chinese international students from February 6 to 12, 2020. The respondents were classified into “the Low-frequency group” (< one time/week; n=144), “the Mid-frequency group” (one-two times/week; n=133), and “the High-frequency group” (≥three times/week; n=175) according to their frequency of using university foodservice. The dietary life was compared among the three groups. Binominal logistic regression models were constructed to determine the associations between the frequency of university foodservice use and the changes in dietary life.
Results
More than 2/3 (68.1%) of the respondents used the university foodservice at least once per week. Chinese international students who were males and Han Chinese people, lived on campus, had stayed longer in Korea, and had no cooking facilities tended to use the university foodservice more often. The level of satisfaction with the university foodservice was not high (3.52 out of 5-points). Only 20% ate meals three times per day, and only 22% ate breakfast almost every day. The frequencies of overeating and skipping meals increased after studying in Korea. The frequency of university foodservice use, along with the length of residence in Korea, was associated with these negative changes in dietary life. Overeating (OR=2.11) and skipping meals (OR=1.79) were more likely to increase after studying in Korea in the Mid-frequency group than in the High-frequency group.
Conclusions
The frequency of university foodservice use was associated with the dietary life of Chinese international students in Korea. A high frequency (i.e. ≥three times/week) of using university foodservice may positively affect the dietary life of Chinese international students in Korea.

Current Status of Parents' Monitoring of and Level of Trust in School Lunch Programs: Boyoung Hur, Injoo Choi, Meeyoung Kim, Jinwook Kwon, Jiyoung Lee, Jihyun Yoon; Korean J Community Nutr 2017;22(5):401-412. Published online October 31, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.5.401

OBJECTIVES
The purpose of this study was to investigate the current status of parents' monitoring of school lunch programs and to examine the relationship of parents' school lunch monitoring with their level of trust in school lunch programs.
METHODS
During November 2016, a web survey was conducted with 1,283 parents who had participated in monitoring of school lunch programs. A total of 621 parents completed the questionnaires (48.4% response rate) and the responses from 442 parents were analyzed (34.5% analysis rate) for elementary (n=196) and middle/high school parents (n=246), respectively.
RESULTS
Both the elementary and middle/high school parents most wanted to participate in monitoring 1~2 times per month, which was less frequent than their current practice. They showed the highest experience rate in â€˜food sanitationâ€™ area in both the prior training and actual practice of school lunch monitoring. They most responded â€˜increasing trust in school lunch programsâ€™ as a merit and â€˜lack of parents participating in monitoringâ€™ as a problem of school lunch monitoring. The average levels of trust did not differ between elementary and middle/high school parents. Multiple regression analyses showed that elementary school parents' level of satisfaction in the monitored school lunch programs was positively associated with the parents' level of trust in general school lunch programs. Monitoring frequency and parents' age, in addition to level of satisfaction in the monitored school lunch program, were associated with level of trust in general school lunch programs among middle/high school parents.
CONCLUSIONS
There was room for change in parents' school lunch monitoring programs to meet parents' needs better. Well-managed school lunch monitoring programs contributing to parents' satisfaction with school lunch programs could increase parents' level of trust in school lunch programs.

Effect of a Worksite-based Dietary Intervention Program for the Management of Metabolic Syndrome: Hye Jin Kim, Injoo Choi, Won Gyoung Kim, Kana Asano, Jeongmin Hong, Young Min Cho, Jihyun Yoon; Korean J Community Nutr 2016;21(3):237-246.

OBJECTIVES
To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees.
METHODS
A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests.
RESULTS
Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.
CONCLUSIONS
The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.
