Purpose: We aimed to evaluate effects of a school-based health education for cardiovascular disease (CVD) prevention among high school girls. Methods: Non-randomized cluster trial was conducted by recruiting two female high schools located in Seoul and allocating one school as a cluster to an experimental group and the other school as the other cluster to a control group. Participants were 169 first-year female high school students in two clusters. Of the participants, 84 were recruited in the experimental group and 85 in the control group. An intervention was an eight-week "School-based Health Education for CVD prevention". The experimental group received the intervention, while the control group received a CVD prevention handout. Measures were knowledge, self-efficacy, and health behaviors for CVD prevention. The pre-test and post-test were conducted. Results: The experimental group participating in "School-Based Health Education for CVD Prevention" had significantly higher changes in knowledge, self-efficacy scores to prevent CVD, and health behaviors than the control group over eight weeks. Conclusions The "School-based Health Education for CVD Prevention" program may improve high school students' knowledge and self-efficacy as determinants of health behaviors as well as health behaviors to prevent cardiovascular disease.

Background: Although the primary vaccine coverage rate for coronavirus disease 2019 (COVID-19) in South Korea has exceeded 80%, the coronavirus continues to spread, with reports of a rapid decline in vaccine effectiveness. South Korea is administering booster shots despite concerns about the effectiveness of the existing vaccine. Methods: Neutralizing antibody inhibition scores were evaluated in two cohorts after the booster dose. For the first cohort, neutralizing activity against the wild-type, delta, and omicron variants after the booster dose was evaluated. For the second cohort, we assessed the difference in neutralizing activity between the omicron infected and uninfected groups after booster vaccination. We also compared the effectiveness and adverse events (AEs) between homologous and heterologous booster doses for BNT162b2 or ChAdOx1 vaccines. Results: A total of 105 healthcare workers (HCWs) that were additionally vaccinated with BNT162b2 at Soonchunhyang University Bucheon Hospital were enrolled in this study.Significantly higher surrogate virus neutralization test (sVNT) inhibition (%) was observed for the wild-type and delta variants compared to sVNT (%) for the omicron after the booster dose (97%, 98% vs. 75%; P < 0.001). No significant difference in the neutralizing antibody inhibition score was found between variants in the BNT/BNT/BNT group (n = 48) and the ChA/ChA/BNT group (n = 57). Total AEs were not significantly different between the ChA/ ChA/BNT group (85.96%) and the BNT/BNT group (95.83%; P = 0.11). In the second cohort with 58 HCWs, markedly higher sVNT inhibition to omicron was observed in the omicroninfected group (95.13%) compared to the uninfected group (mean of 48.44%; P < 0.001) after four months of the booster dose. In 41 HCWs (39.0%) infected with the omicron variant, no difference in immunogenicity, AEs, or effectiveness between homogeneous and heterogeneous boosters was observed. Conclusion Booster vaccination with BNT162b2 was significantly less effective for the neutralizing antibody responses to omicron variant compared to the wild-type or delta variant in healthy population. Humoral immunogenicity was sustained significantly high after 4 months of booster vaccine in the infected population after booster vaccination.Further studies are needed to understand the characteristics of immunogenicity in these populations.

Background: Using path analysis, we aimed to examine whether parenting self-efficacy and parenting styles would be significant associates with parenting behavior, and the parenting behavior would be significantly associated with the obesity status of children from socioeconomically vulnerable families. Methods: A cross-sectional study was conducted with 61 parents and their children enrolled in public welfare systems in a community in Seoul, South Korea. Parenting behavior was defined as encouraging a child’s healthy eating habits and was measured using the Child Feeding Questionnaire. Results: In the path model, higher levels of parenting self-efficacy and lower levels of authoritarian parenting were significantly associated with a higher level of parenting behavior, which was significantly associated with lower child body mass index z-scores. Conclusions Community health nurses need to provide intervention strategies for increasing parenting self-efficacy and decreasing authoritarian parenting styles to promote parenting behaviors and childhood obesity prevention among socioeconomically vulnerable families.

Purpose: This study conducted a job analysis of visiting nurses in the process of change. Methods: Participants were the visiting nurses working for the Seoul Metropolitan city. On the basis of the Public Health Intervention Wheel model, two times of the focus group interview (FGI) with seven visiting nurses and one time of the Developing a Curriculum (DACUM) with 34 visiting nurses were performed. A questionnaire survey of 380 visiting nurses was conducted to examine the frequency, importance and difficulty levels of the tasks created by using the FGI and DACUM. Results: Visiting nurses’ job was derived as the theme of present versus transitional roles. The present role was categorized as ‘providing individual- and group-focused services’ and ‘conducting organization management’, while the transitional role was categorized as ‘providing district-focused services’ and ‘responding to new health issues’. The job generated 13 duties, 28 tasks, and 73task elements. The tasks showed the levels of frequency (3.65 scores), importance (4.27 scores), and difficulty (3.81 scores). All the tasks were determined as important, exceeding the average 4.00 scores. The group- and district-focused services of the tasks were recognized as more difficult but less frequent tasks. Conclusion The visiting nurses exert both present and transitional roles. The transitional roles identified in the present study should be recognized as an extended role of visiting nurses in accordance with the current changing healthcare needs in South Korea. Finally, the educational curriculum for visiting nurses that reflects the transitional roles from the present study is needed.

Background: The purpose of this study was to determine whether metabolic syndrome (MetS) and MetS management behaviors would be significantly associated with health-related quality of life (HRQOL) among patients with liver transplantation. Methods: Ninety-four patients who underwent liver transplantation were recruited at an outpatient clinic from a university hospital in Seoul. MetS was defined according to the National Cholesterol Education Program-Adult Treatment Panel III. MetS management behaviors were measured by using the Evaluation Tool of a Lifestyle Habit for MetS Modification. HRQOL was measured by using the Medical Outcomes Study Short-Form Health Survey-36 II and analyzed by categorizing physical and mental quality of life (QOL). Results: The means of physical and mental QOLs were 82.3 and 82.8 scores, respectively. MetS prevalence was 72.3% and a mean of MetS management behaviors was 97.0. MetS prevalence was not significantly associated with either physical or mental QOLs. A total score of the MetS management behaviors was significantly associated with physical (β=0.42, P=0.008) and mental QOLs (β=0.44, P=0.001). Of the MetS management behaviors, diet control and drinking & smoking control were significantly associated with physical QOL (P<0.05 for all). Physical activity, diet control, and drinking & smoking control were significantly associated with mental QOL (P<0.05 for all). Conclusions MetS prevalence may not associate with HRQOL directly but MetS management behaviors may associate with HRQOL among patients with liver transplantation. Therefore, nursing strategies for promoting MetS management behaviors should be enhanced to improve their HRQOL levels in outpatient clinics and community settings.

Purpose: Health behaviors for metabolic syndrome (MetS) prevention should be emphasized from early adulthood. There is little information on psychosocial factors associated with health behaviors for MetS prevention. The aim of this study was to determine whether there would be a mediating effect of perceived stress on the association between social support and health behaviors for MetS prevention among university students. Methods: This cross-sectional and correlation study was conducted with 502 university students in South Korea. Social support, perceived stress, and lifestyle evaluation for metabolic syndrome scales were used. Online questionnaire survey was conducted between November and December 2019. The mediating effect of social support on health behaviors for MetS prevention was analyzed using PROCESS macro program with bootstrapping method to test our hypotheses. Results: Social support directly influenced perceived stress (β=-.35, p<.001) and health behaviors for MetS prevention (β=.14, p=.002). Health behaviors for MetS prevention was indirectly influenced by perceived stress (β=-.25, p<.001). The size of indirect effect of social support on health behaviors for MetS prevention was 0.06. Conclusions The association of social support and health behaviors for MetS prevention was partially mediated by perceived stress among university students. Therefore, a university-based nursing intervention should comprise social support strategies with stress management to promote health behaviors for MetS prevention.
