Older adults living alone face challenges in managing diabetes, yet research on glycemic control in this group is limited. This study analyzed data from the Korean National Health and Nutrition Examination Survey (2016~2021) to identify factors associated with glycemic control in 453 older adults with diabetes living alone. Methods: Glycemic control was categorized as good (glycated hemoglobin [HbA1c]<7.0%) or poor (HbA1c≥7.0%). Complex sample logistic regression examined demographic, disease and health-related, behavioral, and psychological factors associated with glycemic control. Results: Older adults aged ≥80 years had better glycemic control than those aged 65~69 years, while a diabetes duration of ≥15 years and higher body mass index were linked to poorer control. Strength training 5~7 days per week was associated with better control, whereas non-adherence to a healthy diet was unexpectedly linked to better outcomes. Conclusion: These findings highlight the need for tailored interventions to improve diabetes self-management and support healthy aging among older adults living alone. They also offer practical insights into shaping community-based health programs and social support systems for this population.

This study examined sleep-related characteristics among university students and the associations between sleep quality, dietary habits, and diet quality.Three hundred and ninety-three university students (206 men and 187 women) enrolled at universities in the Chungcheong region of Korea participated in this study between November and December 2023. Data on the general characteristics, dietary habits, sleep status, and the Nutrition Quotient (NQ) for adults were collected using a structured questionnaire. The sleep quality was assessed using the Pittsburgh Sleep Quality Index– Korean version (PSQI-K). The participants were classified into a good sleeper group (PSQI-K≤5) and a poor sleeper group (PSQI-K≥6). The dietary habits and NQ scores were compared according to the sleep quality. Compared with good sleepers, poor sleepers had a significantly higher prevalence of eating alone at least once per day (P<0.01) and higher scores for unhealthy dietary behaviors, including overeating, eating quickly, a preference for salty food, skipping meals, and irregular meal timing (P<0.05). Although the total NQ scores and balance and practice domain scores did not differ according to sleep quality, the moderation domain scores were significantly lower among poor sleepers, particularly in men (P<0.05). In conclusion, poor sleep quality among university students was associated with unhealthy dietary habits and lower diet quality related to dietary restraint. These findings highlight the importance of improving sleep quality as a part of health education and dietary intervention programs for university students.

Chronic kidney disease (CKD) patients are hospitalized for various conditions. Hospitalization increases the readmission rate and mortality rate, seriously deteriorating patients’ quality of life. Consequently, it is crucial to analyze the reasons for hospitalization in CKD patients from a broader perspective according to CKD grade. Methods: This is a prospective cohort study of CKD patients entitled the KoreaN cohort study for Outcomes in patients With Chronic Kidney Disease (KNOW-CKD). A total of 2,238 patients were examined, and the reasons for hospitalization were classified into 16 disease categories. The incidence rate ratio (IRR) according to CKD stage was compared using negative bimodal regression analysis. Results: The all-cause hospitalization incidence was 184.96 per 1,000 person-years. The most common reason for hospitalization was circulatory system disease, followed by infection and digestive system disease. Among hospitalizations for acute kidney injury, endocrine-nutrition-metabolic–related illness, blood-related disease, and diseases of the nervous system and sensory organs, IRR increased as CKD grade advanced. The incidence of ophthalmologic surgery during hospitalization increased according to the CKD stage. The IRR of KNOW-CKD patients was 6.19 (95% confidence interval, 5.92–6.48; p < 0.001) compared with the general population. Conclusion: This in-depth analysis of hospitalizations among CKD patients confirmed that CKD patients were hospitalized for various reasons, such as metabolic, ophthalmic, and hematologic diseases. Early detection and intervention regarding causative diseases of CKD are important to reduce the hospitalization burden and improve patients’ quality of life.

We analyzed the manner and cause of death in 1,193 forensic autopsies from the Jungbu province (central part of South Korea) conducted by the National Forensic Service Daejeon Institute in 2022. Analysis of the manner of deaths revealed that 43.1% (514/1,193 cases) were natural deaths; 42.8% (511/1,193 cases) were unnatural deaths; and 14.1% (168/1,193 cases) were unknown. Among the unnatural deaths, the major manner of death was 44.6% (228/511 cases) by accidents, 34.1% (174/511 cases) by suicide, 13.5% (69/511 cases) undetermined, and 7.8% (40/511 cases) by homicide. Among the unnatural deaths, the major causes of death was 38.4% (196/511 cases) by trauma, 20.4% (104/511 cases) by poisoning, and 17.6% (90/511 cases) by asphyxia. Falling was the major cause of death by trauma (58.7%, 115/196 cases), and strangulation was the major cause of death by asphyxia (75.6%, 68/90 cases). Among the natural deaths, heart disease was the major cause (46.7%, 240/514 cases), followed by endocrine, nutritional and metabolic diseases (14.0%, 72/514 cases). A time-series statistical analysis and comparison of the manner and cause of deaths in this province may facilitate more advanced interpretations relating to both public safety and healthcare in the future.

The number of migrant workers is increasing worldwide every year, and their number and role in Korean society is also increasing. However, the poor conditions faced by migrant workers often become a social issue, and it is not uncommon for them to be the subject of forensic autopsies. This study aimed to investigate the current status of medicolegal autopsy on migrant workers in Korea. We collected data of medicolegal autopsies on migrant workers conducted in Korea from 2016 to 2020 by requesting data from the institutions performing medicolegal autopsy. We calculated the autopsy rate and analyzed manner of death and cause of death. The medicolegal autopsy rate for foreign deaths was 16.4%, which was more than five times higher than the autopsy rate for Korean deaths. By manner of death, 43.7% were natural death, 6.4% were homicides, 8.5% were suicides, 23.6% were accidental deaths, 2.7% were undetermined unnatural deaths and 15.0% were unknown. These results showed a high rate of homicide, accidental death, and unknown death compared to Korean. And the proportion of industrial accident deaths and sudden manhood death syndrome were high. Through this study, it was confirmed that medicolegal autopsies are performed at a relatively high frequency when migrant workers die, and the characteristics related to the deaths of migrant workers were identified.

Sudden death during or after percutaneous coronary intervention (PCI) could be led to potential medicolegal disputes. This study aimed to investigate the clinical and postmortem findings in PCI-related deaths-focusing on the current statusto inform preventive strategies against these fatalities. Forty-three cases were retrieved from the National Forensic Service's postmortem records between 2015 and 2021, and the corresponding postmortem findings and clinical information were analyzed. The analyses revealed a relatively consistent annual incidence of PCI-related deaths. Immediate deaths during or shortly after PCI occurred in 17 cases (39.5%), and delayed PCI-related deaths after discharge from the hospital occurred in 26 cases (60.5%). The causes of PCI-related deaths in the postmortem cases were categorized into four groups: PCI complications (11 cases, 26%), acute myocardial infarction (23 cases, 53%), ischemic heart disease (8 cases, 19%), and others (1 case, 2%). Postmortem examinations played a critical role in determining the cause of death and obtaining medical evidence, including pathological findings of the heart as well as those of coronary artery and stent insertion. Our findings suggest that a detailed examination of the heart, coronary arteries, stent status, and atherosclerosis in PCI-related deaths could help provide more accurate information as medical evidence and prevent/resolve potential medicolegal issues. Further, this could advance our understanding of PCI-related deaths and inform future preventive strategies.

We analyzed 1,079 forensic autopsies conducted in 2021 by the National Forensic Service Daejeon Institute from the Jungbu province in the central part of South Korea, for their manner and cause of death. Among the manner of death (n=1,079), 45.3% (n=489) were categorised as unnatural, 39.5% (n=426) as natural, and 15.2% (n=164) were unknown. Among the unnatural deaths (n=489), 40.7% (n=199) were accidents, 36.8% (n=180) were suicides, 14.1% (n=69) were undetermined, and 8.4% (n=41) were homicides. The major causes of unnatural deaths (n=489) were by trauma, causing 34.4% (n=168), poisoning causing 26.8% (n=131), and asphyxia causing 17.2% (n=84). The major cause of death by trauma (n=168) was falling at 46.4% (n=78), and by asphyxia (n=84) was strangulation at 76.2% (n=64). Among natural deaths (n=426), heart disease was the major cause at 49.8% (n=212) followed by vascular disease at 16.7% (n=71). In future, a time-series statistical analysis on the manner and causes of death in Jungbu province may provide insight and allow for more advanced interpretations about both healthcare and public safety.
