Interregional transfer was defined as discordance between the regions of residence and surgery across 6 administrative regions. Logistic regression and Cox proportional hazards models were used to assess associations of transfer with reoperation and visual disability registration, adjusting for demographic characteristics, comorbidities, and socioeconomic factors.Results: Overall, 5,224 patients (9.6%) underwent interregional transfer; 76.4% traveled to the Seoul metropolitan area, the only net recipient region (+12.2%). Jeju (-38.6%) and Gangwon (-28.8%) had the greatest outflow. Transfer was associated with a higher risk of visual disability (adjusted hazard ratio, 1.4; 95% confidence interval: 1.2-1.7; P < 0.001), but not with reoperation (P = 0.960). Surgical delay was more frequent among transferred patients (42.0% vs 33.6%; P < 0.001). Jeju's net outflow decreased from -69.8% in 2018 to -2.6% in 2023.Conclusion: Despite universal health insurance, regional disparities in access to retinal surgery persist in Korea, with services concentrated in the Seoul metropolitan area. Transfer was independently associated with visual disability but not reoperation. The underlying mechanism likely involves referral of complex cases, patient preference, and transfer-related delay, although claims data cannot distinguish their relative contributions. Jeju's rapid improvement in self-sufficiency illustrates the potential for targeted regional investment to reduce these disparities.","PeriodicalId":48543,"journal":{"name":"Epidemiology and Health","volume":" ","pages":"e2026053"},"PeriodicalIF":2.4,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149185352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined temporal changes in chronic kidney disease (CKD), proteinuria, and kidney function in a nationally representative Korean population.Methods: We analyzed serial cross-sectional data from the Korea National Health and Nutrition Examination Survey (2017-2024), including adults aged ≥19 years with serum creatinine and proteinuria measurements. We classified survey periods as pre-pandemic (2017-2019), pandemic (2020-2021), and post-pandemic (2022-2024). Survey-weighted logistic and linear regression models were used to examine associations of pandemic period with CKD, proteinuria, and estimated glomerular filtration rate (eGFR), adjusting for demographic, socioeconomic, metabolic, and lifestyle factors. We also conducted age-stratified analyses.Results: The analysis included 44,831 adults (mean age, 52.8 years; 44.5% men). CKD prevalence rose from 4.65% before the pandemic to 7.88% during and 7.49% after it; proteinuria prevalence nearly doubled (3.27%, 6.68%, and 6.18%, respectively). Relative to the pre-pandemic period, the adjusted odds of CKD were higher during (odds ratio [OR], 1.22; 95% confidence interval [CI]: 1.09-1.37) and after (OR, 1.24; 95% CI: 1.10-1.39) the pandemic. The corresponding associations were larger for proteinuria (OR, 1.34; 95% CI: 1.17-1.53 and OR, 1.33; 95% CI: 1.17-1.51, respectively). Changes in eGFR were minimal, with no significant temporal trend. Associations were strongest among middle-aged and older adults, particularly for proteinuria among adults aged ≥65 years.Conclusion: CKD prevalence increased during and after the COVID-19 pandemic, largely reflecting a sustained increase in proteinuria rather than a decline in eGFR. These findings support ongoing kidney surveillance and measures to reduce cardiometabolic risk, particularly among middle-aged and older adults.","PeriodicalId":48543,"journal":{"name":"Epidemiology and Health","volume":" ","pages":"e2026051"},"PeriodicalIF":2.4,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149026303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence on the nutritional status of North Korean refugee (NKR) and immigrant children in South Korea (SK) remains limited.

Separately, 336 NKR children and 597 immigrant children were recruited between 2021 and 2025.

To assess validity, FFQ estimates were compared with 4 seasonal sets of 3-day dietary records (3DRs). Reproducibility was assessed by administering the FFQ twice, as FFQ1 and FFQ2. Agreement was evaluated using quartile cross-classification, weighted kappa statistics, and crude and energy-adjusted Spearman correlation coefficients. Bland-Altman plots evaluated individual-level agreement. Nutrient and food-group intakes were compared between FFQ1 and FFQ2.Results: The FFQ demonstrated modest relative validity for ranking individuals. Compared with mean 3DR values, same-or-adjacent quartile agreement for energy and 10 nutrients ranged from 68.0% to 82.5%, and crude correlation coefficients ranged from 0.30 to 0.56. Averaging FFQ1 and FFQ2 improved validity metrics, including the energy-adjusted correlation for sugar intake (r=0.54). Bland-Altman plots showed relatively small mean differences for most nutrients, although the limits of agreement were wide and flavonoid intake was generally overestimated. Reproducibility was good, with same-or-adjacent quartile agreement of 81.4% to 90.7% between FFQ1 and FFQ2 and nutrient correlation coefficients of 0.50 to 0.69. Similar consistency was observed for food and dish categories.Conclusion: The tailored 129-item FFQ for Korean adults with obesity showed modest validity for ranking individuals and good reproducibility.

Adults without CVD enrolled in 1992-1995 were followed until 2005. Daily municipality-level NO2 concentrations were estimated using generalized random forests. The primary outcome was time to first incident CVD (stroke or myocardial infarction).

Diagnosed patient counts, claims-based annual prevalence, and expenditures were calculated for each condition. Exploratory segmented negative binomial regression assessed changes around 2020.Results: Diagnosed patient counts increased for diabetes (12,839 to 16,747), obesity (2,253 to 3,468), and precocious puberty (106,238 to 206,251); among males aged 5-9 years with precocious puberty, counts increased 5.5-fold. Claims-based annual prevalence increased for diabetes (0.13% to 0.21%) and precocious puberty (1.11% to 2.60%), whereas obesity peaked at 0.09% in 2021 before declining to 0.04% in 2023. All conditions showed significant pre-2020 upward trends. Diabetes showed no significant level or slope change; obesity showed no significant immediate level change but a significant downward slope change relative to the pre-2020 trend; and precocious puberty showed a significant level increase in 2020 without a significant subsequent slope change.
