Background: This study aimed to investigate the prevalence, management, and comorbidities of diabetes mellitus among Korean adults. Methods: Data from the Korea National Health and Nutrition Examination Survey (2019–2022) were analyzed to assess the prevalence, treatment, risk factors, and comorbidities of diabetes. Comparisons between young and older adults with diabetes were emphasized. Results: Among Korean adults aged ≥30 years, the prevalence of diabetes is 15.5% during 2021–2022. Of these, 74.7% were aware of their condition, 70.9% received antidiabetic treatment, and only 32.4% achieved glycosylated hemoglobin (HbA1c) <6.5%. Moreover, 15.9% met the integrated management targets, which included HbA1c <6.5%, blood pressure <140/85 mm Hg, and low-density lipoprotein cholesterol <100 mg/dL. In young adults aged 19 to 39 years, the prevalence of diabetes was 2.2%. Among them, 43.3% were aware of their condition, 34.6% received treatment, and 29.6% achieved HbA1c <6.5%. Obesity affected 87.1%, and 26.9% had both hypertension and hypercholesterolemia. Among adults aged ≥65 years, the prevalence of diabetes was 29.3%, with awareness, treatment, and control rates of 78.8%, 75.7%, and 31.2%, respectively. Integrated management targets (HbA1c <7.5%, hypertension, and lipids) were achieved by 40.1%. Conclusion Diabetes mellitus remains highly prevalent among Korean adults, with significant gaps in integrated glycemic, blood pressure, and lipid control. Older adults with diabetes show higher awareness and treatment rates but limited integrated management outcomes. Young adults with diabetes bear a significant burden of obesity and comorbidities, alongside low awareness and treatment rates. Therefore, early intervention programs, education, and strategies tailored to younger populations are urgently required.

Background and Objectives: The transformation of pulmonary arterial hypertension (PAH) treatment in Korea, ushered by targeted therapy’s advent, prompted our analysis of baseline attributes, treatment trends, and survival shifts within our single-center registry. Methods: We examined 230 patients (72.6% female, mean age 40.6±17.4 years) diagnosed and/or treated between 1980 and 2021 in our PAH clinic. Given targeted therapy’s introduction and active use since 2007, we compared diagnostic classification, demographics, and treatment patterns at that juncture. Survival analysis encompassed PAH types and the overall population. For historical survival comparison, 50 non-registry patients were retrospectively added, and age-sex matching enabled pooled analysis. Results: Congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) constituted the largest subset (43.0%), trailed by connective tissue disease-associated PAH (CTD-PAH, 29.6%) and idiopathic PAH (IPAH, 19.1%). Post-2007, CTD-PAH proportions surged, notably with an elevated initiation rate of targeted therapy (95.4%). Overall survival rates at 1, 5, and 10 years stood at 91.3%, 77.4%, and 65.8%, respectively, with CHD-PAH exhibiting superior survival to idiopathic or CTD-PAH. Age-sex matching analysis indicated survival disparities between those starting immediate targeted therapy vs. conservative treatment upon diagnosis, especially driven by IPAH. Conclusions In the post-introduction of the targeted therapy era, patients with PAH promptly started treatment right away, and higher survival rates of patients who started initial PAH-targeted therapy were demonstrated. The transition towards early treatment initiation might have likely contributed to the elevated survival rates observed in Korea’s PAH patient cohort.
