Purpose: We aimed to analyze pediatric drowning cases to study age group-related clinical characteristics, such as causes, location, and outcomes, in an under-researched area in South Korea. Methods: From January 1, 2020 through July 20, 2025, we retrospectively analyzed medical records of patients aged 19 years or younger who had experienced drowning and visited Kangwon National University Hospital located in the northern Yeongseo region of Gangwon Province. Their clinical characteristics were compared between those with worse outcomes, defined as hospitalization to the intensive care unit or in-hospital mortality, and those with better outcomes. Results: During the period, 27 patients having undergone drowning accidents visited the hospital. The most frequent location was the bathtub at home in the patients younger than 1 year (all 4 patients), commercial swimming pools in those aged 1-14 years (12 of the 16 patients), and rivers in those aged 15-19 years (all 7 patients). Of the 27 cases, 11 had worse outcomes including 4 mortalities. Patients with worse outcomes had higher percentages of guardian’s negligence, altered mental status, pool or river as the location, implementation of oxygen therapy or positive pressure ventilation, and lower mean initial Korean Triage and Acuity Scale (i.e., higher acuity), as well as higher mean concentrations of glucose, urea nitrogen, aspartate aminotransferase, and base deficit. Conclusion This study on pediatric drowning patients in the under-researched area showed age-related differences in the primary causes of drowning and clinical features related to the worse outcomes. These findings need to be considered for prompting increased parental vigilance and more comprehensive societal preventive measures.

Objective: We evaluated prognostic factors for pediatric drowning patients. The association between functional outcomes and clinical factors was investigated. Methods: A retrospective cohort study was conducted using data for pediatric drowning patients from the Korean Community-based Severe Trauma Survey from 2016 to 2020. The primary outcome was a good prognosis at discharge, defined as a Glasgow Outcome Scale score of 5. A multivariable logistic regression analysis was performed to evaluate independent factors associated with the primary outcome. Results: From 237,616 patients, we identified 406 drowning patients aged ≤19 years (mean age, 8.8 years). At discharge, 41.0% of those patients had a good recovery. The absence of prehospital cardiac arrest (adjusted odds ratio [aOR], 98.7; 95% confidence interval [CI], 32.9–295.8), indoor location (aOR, 4.0; 95% CI, 1.7–9.3), and transfer to a high-volume hospital (aOR, 2.5; 95% CI, 1.1–5.8) were significant independent factors associated with a good outcome. Age, sex, the intent of injury, and prehospital time were not associated with the outcome. Conclusion Our study identified independent prognostic factors for drowning patients, highlighting the importance of prehospital conditions and hospital care settings in determining outcomes. These findings could be useful in developing clinical strategies for managing such patients.

Objectives: Poor oral hygiene is known to be associated with gastric cancer, but this remains controversial. In this study, we investigated the association between oral health and gastric cancer in Korean adults using data from the Korea National Health and Nutrition Examination Survey. Methods: We analyzed data of 79501 patients with gastric cancer and 41856805 individuals without gastric cancer (control group) using the 7th and 8th Korea National Health and Nutrition Examination Survey (2016–2019) records. Layer and colony variables and weights were used for the complex sample design. We performed logistic regression analysis of complex samples to analyze factors that affect gastric cancer development. Results: Patients with gastric cancer were older and had a higher prevalence of hypertension, hyperlipidemia, and diabetes and a higher rate of current smoking and alcohol consumption than individuals without gastric cancer (p<0.001). Regarding oral health-related factors, the prevalence of very uncomfortable chewing difficulty was significantly higher in patients with gastric cancer (14.4% vs. 3.6%, p<0.001). On multivariate analysis of factors associated with gastric cancer, chewing difficulty showed the highest odds ratio (5.351, 95% confidence interval 2.128–8.982). Patients with very uncomfortable chewing difficulty had high rates of previous dental nerve treatment, gum disease treatment, tooth extraction or intraoral surgery, and prosthetic repair (p<0.001). Conclusions Oral health-related chewing difficulties were associated with gastric cancer, which may be attributable to poor oral hygiene and degradation of oral microbiota. Patients at risk of gastric cancer warrant timely medical interventions to address their oral health and chewing difficulties.

Purpose: This study explored the factors influencing the health-related life satisfaction of people with disabilities who engaged in physical activity, by age and gender. Methods: A secondary analysis was conducted of the 2020 Third Disability and Life Dynamics Panel (2021). The participants were 2,796 people who performed regular physical activity at least once a week. The variables selected were disability-related factors (degree of disability, multiple disabilities, and type of disability), sociodemographic factors (age, gender, living alone, and mean monthly family income), and health-related factors (amount of physical activity, self-esteem, depression, chronic disease, subjective health, and health-related life satisfaction). Descriptive statistics, the chi-square test, the t-test, two-way analysis of variance, and multiple regression analysis were conducted. Results: In total, 58.0% of participants were male, and 42.0% were female. For age groups, 14.4% were children/adolescents (0–19 years), 42.6% were adults (20–59 years), and 43.0% were seniors (≥60 years). The mean score for health-related life satisfaction was 5.0±2.15 out of 10. Adults and seniors whose level of physical activity met or exceeded recommendations had higher subjective health. Moreover, men had better subjective health than women in seniors. Health-related life satisfaction was higher among those who had higher self-esteem, were not depressed, did not have chronic diseases, and had better subjective health. Conclusion Gender significantly influenced health-related life satisfaction in children/ adolescents and seniors. Disability-related factors were significant in adults, and health-related factors were significant in all age groups. Therefore, these factors should be considered when designing interventions to promote subjective health and health-related life satisfaction of people with disabilities.
