Hypertension is a major risk factor for cardiovascular disease and a prevalent chronic condition among Korean adults. Dietary management, particularly sodium reduction, plays an important role in controlling hypertension. Nutrition labels may help individuals make healthier food choices, but their actual use and relationship with dietary intake among Korean adults with hypertension remain insufficiently understood.This study examined the awareness and the use of nutrition labels and assessed their association with the nutrient intake, with a focus on checking sodium information on nutrition labels among Korean adults with hypertension. The participants were 4,692 adults aged 35 years or older with hypertension selected from the 2022~2024 Korea National Health and Nutrition Examination Survey. Awareness, use, and the self-reported influence of nutrition labels on food choice were assessed. The nutrient intake was estimated from 24-hour dietary recall data. All analyses accounted for the complex survey design and were adjusted for age, sex, education level, income, and total energy intake. Overall, 66.5% of participants were aware of the nutrition labels, but only 32.8% used the labels. Among label users, 78.1% reported that labels influenced food choices. The nutrients most frequently checked were energy (23.1%) and sugar (22.7%), whereas sodium received relatively less attention (11.6%). No significant differences were observed in the sodium intake or most other nutrient intakes depending on whether sodium information on nutrition labels was checked. These findings suggest that nutrition label use remains limited, and policy-level strategies and targeted nutrition education interventions are needed to promote sodium reduction among adults with hypertension.

Objective: In South Korea, there is a significant gap in systematic, evidence-based research on intensive case management (ICM) for individuals with severe mental illness (SMI). This study aims to evaluate the effectiveness of ICM through a randomized controlled trial (RCT) comparing ICM with standard case management (non-ICM). Methods: An RCT was conducted to assess the effectiveness of Seoul-intensive case management (S-ICM) vs. non-ICM in individuals with SMI in Seoul. A total of 78 participants were randomly assigned to either the S-ICM group (n=41) or the control group (n=37). Various clinical assessments, including the Brief Psychiatric Rating Scale (BPRS), Montgomery–Åsberg Depression Rating Scale, Health of the Nation Outcome Scale, and Clinical Global Impression-Improvement (CGI-I), along with quality-of-life measures such as the WHO Disability Assessment Schedule, WHO Quality of Life scale, and Multidimensional Scale of Perceived Social Support (MSPSS) were evaluated over a 3-month period. Statistical analyses, including analysis of covariance and logistic regression, were used to determine the effectiveness of S-ICM. Results: The S-ICM group had significantly lower odds of self-harm or suicidal attempts compared to the control group (adjusted odds ratio [aOR]=0.30, 95% confidence interval [CI]: 0.21–1.38). Psychiatric symptoms measured by the BPRS and perceived social support measured by the MSPSS significantly improved in the S-ICM group. The S-ICM group also had significantly higher odds of CGI-I compared to the control group (aOR=8.20, 95% CI: 2.66–25.32). Conclusion This study provides inaugural evidence on the effectiveness of S-ICM services, supporting their standardization and potential nationwide expansion.

This study examined the KHEI (Korean Healthy Eating Index) in elderly men and women according to their income level using the National Health and Nutrition Survey (2020∼2021) data. The income level was classified into lower, lower middle, upper middle, and upper groups according to the household income quartiles. The significant differences between the KHEI score and three subcategories (adequacy, moderation, energy balance) scores according to the income level showed the same pattern in the elderly total, men and women. Regarding the individual item, the score for the intake of meat, fish, eggs, legumes, total fruit, fresh fruit, total vegetables, and vegetables excluding kimchi and pickled vegetables were significantly lower in the lower income group in total elderly, men and women than in the other groups (P＜0.001). Among the items that showed differences between elderly men and women, the ‘regular breakfast’ score was lowest in the upper-income group of elderly men and the ‘mixed grains intake’ score was lowest in the lower-income group of elderly men. These results can be used to help develop nutrition policies and national nutritional interventions for the elderly population according to the income level.

This study presents the nutrition survey methods and the updated food composition database for the Korean Genome and Epidemiology Study (KoGES). The KoGES, which is the largest and longest cohort study in Korea, aims to identify genetic and environmental factors associated with chronic diseases. This study has collected dietary data using a validated semi-quantitative food frequency questionnaire and/or the 24-hour recall method. However, these dietary survey methods use different food composition databases, and their nutritional values are out of date. Therefore, it became necessary to update the food composition database by revising nutrient analysis values to reflect improvements in the performance of food ingredient analysis equipment, revising international values to analysis values of Korean agricultural products, adjusting nutrient units, and adding newly reported nutrients related to chronic diseases. For this purpose, we integrated the different food composition databases used in each nutrition survey, updated 23 nutrients, and expanded 48 new nutrients for 3,648 food items using the latest reliable food composition databases published by national and international institutions. This revised food composition database may help to clarify the relationship between various nutrients and chronic diseases. It could serve as a valuable resource for nutritional, epidemiological, and genomic research and provide a basis for determining public health policies.
