Nutrition education programs necessary for social welfare facilities for persons with disabilities: a cross-sectional study: Jinkyung Kim, Min-Sun Jeon; Korean J Community Nutr 2024;29(1):1-15. Published online February 29, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.1.1

Abstract PDF: Objectives
This study investigated the need for nutrition education aimed at improving the health of residents and users of social welfare facilities for persons with disability and aimed to provide basic information for developing a nutrition education program that meets the needs of the field.
Methods
Altogether, 249 employees working in social welfare facilities for people with disabilities were included in the study. Data on the health status of residents/users, meal management, nutritional education, nutritional education needs, and awareness of nutritional education were obtained through online surveys. A descriptive analysis was conducted to analyze the demographic characteristics, needs, and perceptions of the respondents, and independent t-tests and χ² tests were performed to analyze and compare the differences between residential and daycare facilities.
Results
The majority of residents/users of social welfare facilities for persons with disabilities have developmental disabilities. When educating residents with residents/users of social welfare facilities, ‘personal hygiene’ was the most necessary topic, followed by ‘obesity management’ education. Regarding the methods of providing education, face-toface lectures demonstrated a high demand. They responded that when nutrition education experts provide nutrition education to people with disabilities, they must understand ‘the physical characteristics of persons with disabilities’ and have the ability to determine appropriate nutrition for such people. The most appropriate nutrition program training would be twice a year, lasting 30 min to 1 h per training session.
Conclusions
It will present a direction for operating a nutrition education program for persons with disabilities that meets their needs of social welfare facilities and ultimately contribute to the establishment and activation of nutrition education tailored to welfare facilities for such individuals in Korea.

Knowledge on complementary foods of mothers with young children and their perception of convenience complementary foods: Yoojeong Joo, Jihyun Yoon, Linxi Huang, Youngmin Nam; Korean J Community Nutr 2024;29(1):16-33. Published online February 29, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.1.16

Objectives
The purpose of this study was to examine mothers’ knowledge levels on complementary foods and their perception of convenience complementary foods.
Methods
An online survey was conducted with mothers aged 20–49 years who had purchased convenience complementary foods and had a preschool child aged 4 months or older. The respondents were categorized into 3 groups based on their knowledge scores: low- (0–50 points), mid- (55–65 points), and high- (70–100 points) knowledge groups.
Results
The average score of mothers’ knowledge on complementary foods was 58.8 out of 100 points. Working mothers were found to have lower levels of knowledge compared to mothers who were housewives. Only 1/4 of responding mothers had educational experience on complementary foods. Mothers expressed a desire for information on the types of complementary foods (72.2%) and the intake amounts (60.3%) corresponding to each phase of their child’s development. Multivariate analysis of variance revealed significant differences in health (P = 0.002), variety (P = 0.039), and hygiene (P = 0.041) among the factors taken into consideration when purchasing convenience complementary foods according to the mothers’ knowledge levels. Mothers in the high-knowledge group placed a greater importance on ‘balanced nutrition’ (P = 0.022) and ‘hygienic cooking’ (P = 0.010) compared to mothers in the low-knowledge group. The results of the modified importance-performance analysis, which compared the importance and performance of the factors taken into consideration when purchasing convenience complementary foods, highlighted the need for efforts in ‘health,’‘hygiene,’ and ‘price,’ while also indicating an excessive effort in ‘convenience.’ Conclusions: This study suggests expanding relevant education programs to enhance mothers’ knowledge on complementary foods, especially for working mothers. In the industry, marketing strategies for complementary food products could be developed that align with the needs of mothers, focusing on health, hygiene, and price.

Sustainable diets: a scoping review and descriptive study of concept, measurement, and suggested methods for the development of Korean version: Sukyoung Jung; Korean J Community Nutr 2024;29(1):34-50. Published online February 29, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.1.34

Abstract PDF: Objectives
Transformation through a sustainable food system to provide healthy diets is essential for enhancing both human and planetary health. This study aimed to explain about sustainable diets and illustrate appropriate measurement of adherence to sustainable diets using a pre-existing index.
Methods
For literature review, we used PubMed and Google Scholar databases by combining the search terms “development,” “validation,” “sustainable diet,” “sustainable diet index,” “planetary healthy diet,” “EAT-Lancet diet,” and “EAT-Lancet reference diet.” For data presentation, we used data from National Health and Nutrition Examination Survey, 2017–2018, among adults aged 20 years and older (n = 3,920). Sustainable Diet Index-US (SDI-US), comprising four sub-indices corresponding to four dimensions of sustainable diets (nutritional quality, environmental impacts, affordability, and sociocultural practices), was calculated using data from 24-hour dietary recall interview, food expenditures, and food choices. A higher SDI-US score indicated greater adherence to sustainable diets (range: 4–20). This study also presented SDI-US scores according to the sociodemographic status. All analyses accounted for a complex survey design.
Results
Of 148 papers, 16 were reviewed. Adherence to sustainable diets fell into 3 categories: EAT-Lancet reference diet-based (n = 8), Food and Agriculture Organization (FAO) definitionbased (n = 4), and no specific guidelines but including the sustainability concept (n = 4). Importantly, FAO definition emphasizes on equal importance of four dimensions of diet (nutrition and health, economic, social and cultural, and environmental). The mean SDI-US score was 13 out of 20 points, and was higher in older, female, and highly educated adults than in their counterparts.
Conclusions
This study highlighted that sustainable diets should be assessed using a multidimensional approach because of their complex nature. Currently, SDI can be a good option for operationalizing multidimensional sustainable diets. It is necessary to develop a Korean version of SDI through additional data collection, including environmental impact of food, food price, food budget, and use of ready-made products.

Association of ultra-processed food with diabetes and impaired fasting glucose in elderly populations (urban and rural): a cross-sectional study: Seung Jae Lee, Mi Sook Cho; Korean J Community Nutr 2024;29(1):51-64. Published online February 29, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.1.51

Abstract PDF: Objectives
This study examined the association between ultra-processed food (UPF) consumption and chronic diseases in elderly Koreans.
Methods
Data from the 2019–2021 Korea National Health and Nutrition Examination Survey were analyzed. Dietary intake and UPF consumption were assessed using the NOVA food classification based on 24-hour recall data from 3,790 participants (aged 65+ years). Participants were divided into 4 groups based on the quartile of energy intake from UPFs. Regions were classified as urban or rural. Multivariable logistic regression was employed to estimate the adjusted odds ratios (AORs) with 95% confidence intervals (CIs) after controlling for potential confounders.
Results
Among the participants, 71.3% resided in urban and 28.7% in rural areas. Compared to the urban elderly, rural participants tended to be older, have lower education and income levels, be more likely to live in single-person households, and have a higher smoking rate (P < 0.05). Urban elderly consumed more UPFs daily (146.1 g) compared to rural residents (126.6 g; P < 0.05). “Sugar-sweetened beverages” were the most consumed category in both regions. “Sweetened milk and its products” and “traditional sauces” were prominent in urban areas, while rural elderly consumed more “traditional sauces” and “distilled alcoholic beverages.” Rural areas also had a higher carbohydrate-to-calorie ratio than urban areas. Compared to the lowest quartile of UPF intake, the highest quartile was significantly associated with impaired fasting glucose only in rural areas (AOR, 1.48; 95% CI, 1.00–2.19; P for trend = 0.0014). No significant associations were observed for diabetes in either urban or rural areas.
Conclusions
This study suggests that high intake of UPFs is associated with increased odds of impaired fasting glucose in rural elderly. Further research is needed to elucidate the specific negative health effects of UPFs in different populations, and targeted efforts should promote healthy diets in both urban and rural areas.

Comparative study on the health and dietary habits of Korean male and female adults before and after the coronavirus disease 2019 pandemic: utilizing data from the 8 th Korea National Health and Nutrition Examination Survey (2019–2021): Chaemin Kim, Eunjung Kim; Korean J Community Nutr 2024;29(1):65-80. Published online February 29, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.1.65

Abstract PDF

Objectives
This study aims to compare changes in physical factors, health behaviors, eating habits, and nutritional intake among Korean male and female adults over a period of three years (2019–2021) before and after the outbreak of coronavirus disease 2019 (COVID-19).
Methods
This study utilized raw data from the 8^th Korea National Health and Nutrition Examination Survey (2019–2021). The participants in this study included 6,235 individuals in 2019, 5,865 individuals in 2020, and 5,635 individuals in 2021. Individuals whose daily energy intake was less than 500 kcal or exceeded 5,000 kcal were excluded from the study.
Results
In comparison to 2019, overweight/obesity rates, weight, waist circumference, weekend sleep hours, and resistance exercise days/week increased in both male and female during the COVID-19 pandemic. Regarding eating habits, the proportions of people skipping breakfast, not eating out, consuming health supplements, and recognizing nutritional labels increased in 2020 and 2021, whereas the rate of skipping dinner decreased. Total energy intake has continued to decrease for the two years since 2019. A comparison of nutrient intake per 1,000 kcal before and after the outbreak of COVID-19 revealed that intake of nutrients, including protein, phosphorus, iron, vitamin A, riboflavin, and niacin increased, while folic acid intake decreased. In male, calcium, phosphorus, riboflavin, and niacin intakes increased, whereas iron, vitamin C, and folic acid intakes decreased. In female, phosphorus, iron, vitamin A, and riboflavin intake increased significantly, while protein and niacin intake decreased significantly.
Conclusions
After COVID-19, the obesity rate, breakfast skipping rate, health supplement intake, and nutritional label use increased, while the frequency of eating out, dinner skipping rate, and total energy intake decreased. These environmental changes and social factors highlight the need for nutritional education and management to ensure proper nutritional intake and reduce obesity rates in the post-COVID-19 era.
