Purpose: This study aimed to examine the current status and key challenges of pediatric nursing clinical education in South Korea and to provide strategic directions for quality improvement based on competency-based learning outcomes. Methods: A cross-sectional survey was conducted among 89 pediatric nursing faculty members working at various universities nationwide between February and July 2024. Quantitative data were analyzed using descriptive statistics, and qualitative responses were analyzed using inductive content analysis. Results: Practicum objectives primarily focused on inpatient care (98.9%) and core nursing skills (83.1%), while communication and problem-solving (22.4%) and ethics (21.3%) were underrepresented. Although high-fidelity simulation use reached 33.7%, interactive tools such as virtual reality (17.9%) and nursing process evaluations (7.8%) remained underutilized. Six themes emerged from the analysis of faculty perspectives on enhancing clinical practicum education: structural barriers in securing sites, inconsistent learning environments, overcrowding, limitations of observation-only learning, regulatory constraints, and excessive faculty burden. Conclusion This study proposes establishing standardized clinical protocols, expanding hybrid simulation-based models to compensate for shrinking clinical sites, and institutionalizing industry-academic cooperative frameworks to ensure the quality and equity of pediatric nursing education. These approaches are essential to enhancing the quality and equity of pediatric clinical nursing education in Korea.

Purpose: To investigate the factors contributing to child maltreatment in Indonesia during the COVID-19 (coronavirus disease 2019) pandemic, highlighting the overlooked impact of parenting practices on various maltreatment forms during this unprecedented period. Methods: Using a cross-sectional design, the research used the ICAST-C (Indonesian version of Child Abuse Screening Tools for Children) tool to assess instances of child maltreatment. The study consisted of 219 high school students from Bekasi and Bandung City in West Java, Indonesia, selected through a stratified proportionate random sampling approach, followed by recruitment and consent procedures. An online questionnaire facilitated data collection, which was analyzed using multivariate logistic regression. Results: Children experiencing parental rejection were significantly more likely to face violence (adjusted odds ratio [AOR], 2.99; p<.001). Rejection-based parenting was identified as a significant causal factor contributing to psychological maltreatment (AOR, 3.59; p<.001), whereas higher parental education levels directly contributed to increased psychological maltreatment (AOR, 1.99; p=.024). Additionally, rejection significantly influenced physical maltreatment (AOR, 5.17; p<.001) and neglect (AOR, 3.29; p<.001). Interestingly, emotional warmth is also linked to heightened neglect (AOR, 2.29; p=.017). These findings highlight rejection as a critical factor influencing overall child maltreatment (AOR, 6.99; p<.001). Conclusion This study establishes a significant causal relationship between parental rejection and various forms of child maltreatment, excluding sexual violence. It emphasizes the need for targeted interventions, such as parenting education and community support, to address parental rejection and promote healthier parenting practices. Longitudinal studies are essential for further exploring these dynamics.

Purpose: This study aimed to analyze the characteristics and trends of domestic research on electronic cigarettes published in Korean academic journals between 2017 and September 2025, with a comparative focus on studies involving adults and adolescents. Methods: The study employed a descriptive literature analysis design. A total of 87 articles were identified through searches of major Korean academic databases (RISS, ScienceON, and DBpia) and selected based on predefined inclusion and exclusion criteria. The studies were classified by research population (adults vs. adolescents) and analyzed according to publication year, study design, data sources, and research themes. Results: A greater number of studies focused on adults than on adolescents, and quantitative research predominated in both groups. Most quantitative studies relied on secondary data; notably, 88.0% of adolescent studies used data from the Korea Youth Risk Behavior Survey (KYRBS). Among adult studies, the most common research themes were health effects and associated factors, whereas adolescent studies most frequently addressed smoking cessation and health effects. Conclusion Although domestic research on electronic cigarettes has steadily increased, it remains concentrated mainly on cross-sectional quantitative designs, with limited use of longitudinal or qualitative approaches. In particular, the excessive reliance on secondary data in adolescent research limits the ability to capture emerging patterns of e-cigarette use and evolving risk perceptions. Therefore, future studies should apply diverse research designs to gain an in-depth understanding of the social and psychological contexts of adolescent e-cigarette use.

Purpose: Adolescents with same-sex or both-sex sexual experience face disproportionate health risks, yet research has predominantly examined single health problems rather than their multidimensional patterns. This study employed latent class analysis (LCA) to identify distinct health typological classes among Korean adolescents and characterize the distribution of sexual behavior patterns across these classes. Methods: We analyzed 278,066 middle- and high-school students in the 2013–2016 Korea Youth Risk Behavior Survey. The LCA used 17 indicators encompassing sexual behavior patterns, health behaviors, health perceptions, and mental health. Complex-sample weighted analyses examined associations between latent classes and sociodemographic characteristics, sexual behaviors, and diseases. Results: Four distinct classes were identified: mental health high-risk group (10.1%), substance use high-risk group (6.5%), average group (36.3%), and healthy group (47.1%). Adolescents with same-sex or both-sex sexual experience were disproportionately concentrated in the two high-risk classes, comprising 3.3% of the mental health high-risk group and 4.1% of the substance use high-risk group, compared with only 0.3% and 0.5% of the average group and the healthy group. The mental health high-risk group exhibited extremely elevated prevalence rates of suicidal ideation (96.2%), depressive symptoms (88.5%), and suicide attempts (27.5%), while the substance use high-risk group showed high rates of smoking (82.4%) and alcohol use (84.6%) but better mental health. Conclusion Adolescents with same-sex or both-sex sexual experience demonstrate health inequality through disproportionate classification in the mental health high-risk group and the substance use high-risk group. The findings underscore the need for integrated interventions combining mental health support and substance use prevention.

Purpose: Digital health literacy is essential for health management among children and adolescents, with multicultural youth being particularly vulnerable to challenges in accessing, appraising, and using digital health information. This study aimed to develop a digital health literacy improvement program (DHL-Up) tailored to multicultural children and adolescents and evaluate its effectiveness. Methods: Guided by the Transactional Model of eHealth Literacy and the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, a five-session program was developed to strengthen functional, communicative, critical, and translational digital health literacy. A non-equivalent control group pretest–posttest design was used. The participants included 31 multicultural children and adolescents aged 10–15 years (experimental group: 14; control group: 17). The experimental group participated in a 5-week online program (60 minutes per session) delivered to small groups via Zoom. Data were collected before and after the intervention and analyzed using descriptive statistics, independent t-tests, Mann-Whitney U tests, chi-square tests, and Fisher’s exact tests. Results: The experimental group showed significantly greater improvements in digital health literacy (t=2.73, p=.011) and the usefulness of Internet health information (t=3.11, p=.004) than the control group. No significant difference was found for information overload (t=-0.17, p=.854). Conclusion This study developed and validated a tailored digital health literacy intervention for multicultural children and adolescents, demonstrating its applicability in schools, public health centers, and community settings. These findings provide foundational evidence to support the institutionalization of digital health literacy education and highlight its potential to mitigate digital health information disparities among vulnerable populations.

Purpose: Weight loss behaviors are common among Korean female adolescents and are often influenced by distorted body image and sociocultural pressures, leading some to unhealthy practices. This study examined biological, psychological, and social factors associated with weight loss behaviors using Engel’s biopsychosocial model. Methods: This secondary analysis utilized data from the 19th Korea Youth Risk Behavior Survey (2023), focusing on 21,632 female middle and high school students. Logistic regression was conducted to analyze associations between weight loss behaviors and biopsychosocial variables such as body mass index (BMI), grade level, stress, anxiety, body image distortion, smoking, and nutrition education experience. Results: Among female adolescents, 46.5% reported having attempted weight loss. In logistic regression analysis, biological factors (grade level and BMI percentile), psychological factors (perceived stress, distorted body image, generalized anxiety disorder risk, and smoking), and social factors (nutrition education) were significantly associated with weight loss behaviors. Key predictors included being in middle school (odds ratio [OR], 1.22), higher BMI, elevated stress, distorted body image (OR, 1.90), generalized anxiety, smoking (OR, 1.53), and lack of nutrition education (OR, 1.10). Psychological factors, especially body image distortion and emotional distress, emerged as major contributors to weight loss behaviors. Conclusion Weight loss behaviors among Korean female adolescents are influenced by complex biopsychosocial factors beyond physical health concerns. Nursing interventions should incorporate emotional regulation, body image education, and school-based health literacy programs. Early identification through multidimensional assessment is crucial for effective prevention.

Purpose: This study is a descriptive survey examining the effects of stress, loneliness, and emotional dysregulation on adolescents’ potential for drug use. Methods: Data were collected through face-to-face surveys conducted between August 28 and September 11, 2023, with a sample of 118 second-year students from a middle school in South Korea. The survey questionnaire included items on general characteristics, substance-related characteristics, adolescent stress, loneliness, emotional dysregulation, and drug use potential. Results: The analysis revealed significant differences in drug use potential based on academic achievement, school satisfaction, family relationship satisfaction, economic status, smoking experience, and substance use history. Furthermore, drug use potential showed a significant positive correlation with stress, loneliness, and emotional dysregulation. The key predictors of drug use potential were loneliness in family relationships, emotional dysregulation, and school satisfaction with a total explanatory power of 33.8%. Conclusion To prevent adolescent drug use potential, it is essential to develop and implement nursing intervention programs that reduce family-related loneliness, provide support for emotional regulation difficulties, and promote smoking prevention.

Purpose: Although pertussis is a vaccine-preventable disease, its incidence increased rapidly in Guro-gu, Seoul, since May 2024. This study aimed to investigate the epidemiological characteristics of pertussis cases and outbreaks during this period. Methods: Data from epidemiologic investigations of 355 laboratory-confirmed pertussis cases reported in 2024 in Guro-gu, Seoul, were analyzed using national surveillance records. Demographics, vaccination status, outbreak-associated educational settings, and symptom-to-test intervals were analyzed using descriptive statistics and non-parametric tests. Results: Between May and December 2024, 355 cases were reported, 85.4% of which occurred among school-aged children and adolescents, representing a marked increase compared with previous years. Outbreaks were identified in two elementary schools, three middle schools, and four private academies, indicating clustered transmission in educational settings, with school-based attack rates ranging from 3.2% to 6.3%. Among 146 outbreak-associated school cases, 95.4% had completed age-appropriate vaccination on time. The symptom-to-test interval showed a right-skewed distribution (median, 6 days; interquartile range, 3–11), with longer delays observed in high school students. Conclusion The sharp increase in pertussis cases among school-aged children underscores the need for strengthened surveillance in educational settings and improved timeliness of testing to reduce transmission. Delays in symptom-to-test intervals and the occurrence of cases despite age-appropriate vaccination suggest possible waning immunity, highlighting the importance of evaluating booster vaccination strategies and targeted age-specific public health interventions.

Purpose: This study examined the effects of upright nesting compared with swaddling on physiological status, sleep duration, and feeding tolerance in preterm infants in the neonatal intensive care unit. Methods: A total of 48 preterm infants, 24 per group, with gestational ages of 31 to 36 weeks, were enrolled. During the study, all infants were fed every 2 hours and did not receive sedation. Those requiring respiratory support or presenting with congenital abnormalities were excluded. At the unit level, participants were assigned to the “upright nesting” or the “swaddling” group. Physiological parameters, such as body temperature, oxygen saturation, heart rate, and respiratory rate, as well as sleep duration and feeding tolerance, were measured over 3 consecutive days. To examine group effects, time effects, and group-by-time interactions, linear mixed models were applied. Results: Baseline characteristics, including sex, birth weight, and gestational age, were comparable between groups. Infants receiving upright nesting showed higher mean body temperature and oxygen saturation, lower heart rate, longer sleep duration, and improved feeding tolerance. Linear mixed models presented significant main effects of time for temperature, oxygen saturation, and heart rate, while significant group effects were presented for sleep duration and feeding tolerance. Group by time interactions were not statistically significant, suggesting favorable trends without differential change over time. Conclusion Upright nesting supports physiological stability, promotes longer sleep duration, and enhances feeding tolerance in preterm infants. Furthermore, it is a promising supportive strategy in neonatal intensive care, but larger studies are needed to confirm the results.

Purpose: Early adolescence is a pivotal developmental stage characterized by rapid physical, emotional, and social changes. Happiness during this period is crucial as it influences later life outcomes. This study examined 4-year changes in happiness and identified predictors among Korean early adolescents. Methods: A secondary analysis of longitudinal panel data was conducted using latent growth modeling to assess changes in happiness over 4 years, utilizing data from the Panel Study on Korean Children (11th–14th waves) with a total of 1,177 participants. Descriptive statistics were computed using IBM SPSS ver. 29.0, and latent growth modeling, including unconditional and conditional models with associated factors variables, was conducted using IBM AMOS ver. 29.0. Results: A nonlinear trajectory was identified with a sharp decline in happiness, particularly between the ages of 11 and 12 years. Self-esteem, peer attachment, and a creative school environment emerged as protective factors mitigating this decline, whereas parental attachment influenced baseline happiness but not its trajectory. Higher self-esteem, stronger peer attachment, and supportive school environments were associated with a slower decline in happiness. Conclusions Our findings highlight the importance of early interventions beginning around the age of 11 years, a critical period when happiness decreases more steeply. Practical implications include developing school-based and psychosocial programs that strengthen self-esteem and positive peer relationships, and fostering autonomy-supportive, creative educational environments. Coordinated efforts between schools and families are essential to promote adolescents’ emotional well-being and ensure balanced development in academic and socio-emotional domains.
