Psychometric Properties of the Korean Version of the Smoking Media Literacy Scale for Adolescents

Smoking media literacy has proven to be an effective competency for reducing adolescents' smoking. This study aimed to cross-culturally modify the smoking media literacy scale and evaluate the validity and reliability of the Korean version of the revised Smoking Media Literacy Scale for Adolescents (K-SMLS). The translation of the K-SMLS was conducted according to the World Health Organization's guidelines. After the translation process, an online survey was conducted with convenience samples of 215 total adolescents from five high schools in the capital city of Korea. Construct validity was examined by exploratory factor analysis and confirmatory factor analysis. Internal consistency reliability was examined with Cronbach's alpha. The final version of the K-SMLS consisted of 15 items. The goodness of fit, determined through a confirmatory factor analysis of the three domains, was acceptable [χ2 = 237.85 (p < 0.001), CFI = 0.93, TLI = 0.92, RMSEA = 0.09, SRMR = 0.09]. The reliability of the K-SMLS was satisfactory (Cronbach's alpha = 0.79). The findings provide evidence for a valid and reliable tool that can be used to assess smoking media literacy in Korean adolescents. Further studies with a probability sampling design are suggested as the use of convenience samples limits the generalizability of the results to other populations

Variation simulation and diagnosis considering in-plane/out-of-plane welding distortion

Geometric variation including welding distortion accumulates as many parts are joined together, ultimately affecting the final product. This variation is then subjected to correction, which requires considerable effort, time, and cost. This variation can be categorized as in-plane/out-of-plane variation. To date, studies on variation simulation have largely focused on the out-of-plane variation, however the variation generated in the in-plane direction requires more time and efforts to correct afterwards. This research aims to construct a variation simulation model considering both the in-plane and out-of-plane variations. A geometric analysis was performed to derive an equation that reflects the coupling effect of the out-of-plane variation on the in-plane variation. The proposed model is validated with case study analysis and the results shows that good fidelity in predicting and diagnosing the in-plane variation during the block assembly process considering welding distortion.

Factors Affecting Secondhand Smoke Avoidance Behavior of Vietnamese Adolescents

The purpose of this study was to examine the stage of secondhand smoke avoidance behavior of adolescents in rural areas of Vietnam and the related factors affecting such behavior. The participants were recruited from two middle schools located in Hai Thuong and Trieu Trach commune, Vietnam. Data were collected in January 2016 by distributing and collecting a self-administrated questionnaire. The collected data were analyzed (n = 166) using SPSS 21.0 for frequency, percentage, and ordinal logistic regression. The largest proportion of secondhand smoke avoidance behavior was classified in maintenance (41.6%), followed by action (19.9%), preparation (15.1%), pre-contemplation (13.3%), and contemplation (10.2%) stages. The factors related to higher secondhand smoke avoidance behavior were higher self-efficacy (p = 0.003) and more frequent discussion with parents about dangers of smoking (p = 0.001). The findings indicated that self-efficacy of avoiding secondhand smoke and discussion with parents were associated with secondhand smoke avoidance behavior of adolescents. These findings can be used for developing education programs to prevent secondhand smoke for adolescents in Vietnam

Influence of social responsibility and pandemic awareness of nursing students on COVID-19 preventive behaviours: a cross-sectional online survey in South Korea

Objectives Factors influencing COVID-19 preventive behaviour require exploration to strengthen the response competencies of prehealthcare professionals and reduce the pandemic’s impact. This study aimed to identify the level of COVID-19 preventive behaviour among Korean nursing students and to determine the influence of social responsibility and pandemic awareness to present educational strategies for reducing disaster impact.Methods and analysis As a cross-sectional descriptive survey study using an online questionnaire, the participants were convenience sampled from one online community for nursing students and three nursing colleges located in Seoul, South Korea. The data from 590 participants were analysed by t-test, analysis of variance, Pearson’s correlation and linear multiple regression using SPSS.Results The factors influencing COVID-19 preventive behaviour were identified to be social responsibility (linear regression coefficient 0.354, 95% CI 0.243 to 0.464), pandemic awareness (linear regression coefficient 0.131, 95% CI 0.025 to 0.237), impact of COVID-19 on daily life (linear regression coefficient 0.085, 95% CI 0.019 to 0.152) and living in Daegu/Gyeong-buk area (linear regression coefficient 0.134, 95% CI 0.024 to 0.244).Conclusion Based on the findings that social responsibility and pandemic awareness are key predictors of COVID-19 preventive behaviour, customised educational programmes and additional studies are recommended for raising social responsibility and pandemic awareness among prehealthcare professionals as a part of disaster response

Effect of a Pedometer-Based, 24-Week Walking Intervention on Depression and Acculturative Stress among Migrant Women Workers

Little research has examined exercise-based interventions meant to alleviate depressive symptoms among Korean-Chinese migrant women workers living in Korea. Thus, this study evaluated the effectiveness of a 24-week walking program on reducing depressive symptoms and acculturative stress levels in this population. This quasi-experimental sequential walking program was conducted with 132 Korean-Chinese women over a period of 24 weeks. Participants were divided into either a standard treatment group (n = 69) or enhanced treatment group (n = 63). All participants were instructed to walk using a pedometer. The enhanced treatment group also received mobile text messages designed to encourage walking adherence and improve acculturation. Participants were asked to complete two structured questionnaires, the Centre for Epidemiologic Studies Depression Scale and the Acculturative Stress Scale, to evaluate the intervention programs. At the end of the program, both groups exhibited decreased depression scores, but the decrease in the enhanced treatment group was more significant both at weeks 12 and 24. Acculturative stress was also found to have decreased at weeks 12 and 24. Our findings show the walking program reduced the depressive symptoms and acculturative stress levels among the Korean-Chinese women in this study. Further studies will be needed to analyze the relationship between walking step count and mental health considering exercise intensity

The Determinants of Adherence to Public Health and Social Measures Against COVID-19 Among the General Population in South Korea: National Survey Study

BackgroundThe COVID-19 pandemic has created devastating health, social, economic, and political effects that will have long-lasting impacts. Public health efforts to reduce the spread of COVID-19 are the priority of national policies for responding to the pandemic globally. Public health and social measures (PHSMs) have been shown to be effective when used alone or in combination with other measures, reducing the risk of spreading COVID-19. However, there is insufficient evidence on the status of compliance with PHSMs in the general population for the prevention of COVID-19 in public areas, including Korea. ObjectiveThe aim of this study was to assess levels of compliance with the recommended PHSMs against SARS-CoV-2 infection and their predictors among the general population by using national data. MethodsThis study was a secondary data analysis of the National Survey of Infectious Disease Preventive Behaviors in Community, which was conducted by the Korea Centers for Disease Control and Prevention Agency (KDCA) between October 12 and October 30, 2020. The primary study was cross-sectional, using stratified sampling via an adjusted proportional allocation method to select representative samples and ensure the stability of samples. The data were collected through phone interviews conducted by trained enumerators using a structured questionnaire. PHSM adherence was measured using a 10-item comprehensive infectious disease prevention behavior (CIDPB) scale, and each sociocognitive factor, including perceived susceptibility to SARS-CoV-2 infection, perceived severity of SARS-CoV-2 infection, perceived confidence in performing preventive behaviors related to COVID-19, information comprehension ability, and trust in information from the KDCA, was measured. A total of 4003 participants were included in the final analysis. Tobit regression and a decision tree analysis were performed to identify the predictors of preventive measures and the target groups for intervention. ResultsWe discovered that women scored 1.34 points higher on the CIDPB scale than men (P<.001). Compared to the group aged 19 to 29 years, those aged 50 to 59 years and those older than 60 years scored 1.89 and 2.48 points higher on the CIDPB scale (P<.001), respectively. The perceived severity of infection, confidence in preventive behaviors, information comprehension ability, and trust in information from the KDCA were significant positive determinants of CIDPBs (P<.001). The perceived susceptibility to infection showed a significant negative relationship with CIDPBs (P<.001). ConclusionsFemale sex, older age, lower income, and sociocognitive factors were found to be significant determinants of adhering to PHSMs. The findings suggest the need for tailored interventions for target groups; specifically, the age group that was the most active at work indicated the highest potential to spread infection. Adequate public health education and health communication for promoting adherence to PHSMs should be emphasized, and behavior change strategies for those with low perceived confidence in performing PHSMs should be prioritized

Factors Associated with the Health Literacy on Social Determinants of Health: A Focus on Socioeconomic Position and Work Environment

Though impressive progress has been made in healthcare worldwide, many people still experience disproportionate health burdens and inequities in healthcare services. For establishing sustainable development goals, health literacy on social determinants of health (HL-SDH) has been recognized as a key to creating better social and physical environments. In particular, low levels of health literacy among industrial workers are considered as a major barrier to benefitting from the progress made in healthcare. This study aimed to describe levels of HL-SDH and to examine the relationships among socioeconomic status, working environment, and HL-SDH among workers in Korea. A total of 660 workers from an online panel participated in Korea from 30 May to 7 June 2018. The Korean version of HL-SDH instrument consisted of 33 items and four dimensions: access, understand, appraise, and apply. Descriptive statistics, a t-test, ANOVA, and multiple regression analysis were conducted. The mean score of HL-SDH was 2.48. Perceived mental health status, annual income, and the number of employees per worksite were found to be statistically significant factors related to HL-SDH (F = 3.64, p = &lt;0.001). The HL-SDH score was considerably higher, indicating that nursing interventions to enhance HL-SDH are required for health promotion, especially among workers in poor social and working environments

Correlates of Physical Activity in Urban Midwestern Latinas

Background: Latinas (Latino women) are at higher risk than non-Latina white women of cardiovascular disease and stroke, primarily because of higher rates of obesity and type-2 diabetes mellitus. Increases in physical activity help control these cardiovascular risk factors, but a higher percentage of Latinas than white women are inactive. The study goals were to identify personal, social environmental, and physical environmental correlates of physical activity of urban-dwelling, Midwestern Latinas and to obtain their recommendations for increasing exercise in their communities. Methods: A face-to-face interview (Women and Physical Activity Survey) that covered personal, social environmental, and physical environmental correlates of physical activity was performed with 300 volunteer Latinas (242 in Spanish, 58 in English), aged 20 to 50 years, living in Chicago. Physical activity was measured with questions on lifestyle and planned leisure activity (exercise) from the Behavioral Risk Factor Surveillance System survey. Results: The sample consisted of urban-dwelling Latinas who were primarily from Mexico and who spoke predominantly Spanish. The breakdown was as follows: 36% met current recommendations for moderate or vigorous physical activity, 52.3% were insufficiently active, and 11.7% were inactive. Physical activity was higher among younger women, married women, and women with the following characteristics: had some confidence about becoming more active, saw people exercising in the neighborhood, attended religious services, or lived in areas with heavy traffic. Conclusions: Interventions need to focus on encouraging Latinas, especially those who are older, to reach the level of physical activity recommended to benefit health. The church may be a suitable community setting for initiating programs that provide women with the knowledge, skills, and motivation to become more active so that they can bring back to the larger Latina community.https://www.ajpmonline.org/article/S0749-3797(03)00167-3/abstrac

The Sequential Mediating Effects of Dietary Behavior and Perceived Stress on the Relationship between Subjective Socioeconomic Status and Multicultural Adolescent Health

Studies have examined the impact of social determinants of health on the health behaviors and health statuses of ethnic minority adolescents. This study examines the subjective health of this population by examining the direct effects of multicultural adolescents’ subjective socioeconomic status (SES) and the sequential mediating effects of their dietary behaviors and perceived stress. We utilized secondary data of 500 middle school students from multicultural families who participated in the 15th Korean Youth Health Behavior Survey, 2019. Information about SES, perceived stress, subjective health status, and dietary behavior (measured by the breakfast intake frequency during the prior week) were utilized. For the relationship between the SES and the subjective health status, we confirmed the sequential mediating effects of breakfast frequency and perceived stress using SPSS 25.0 and PROCESS macro with bootstrapping. The results showed that SES had a direct effect on subjective health status and indirectly influenced subjective health status through the sequential mediating effect of breakfast frequency and perceived stress. However, SES had no direct effects on perceived stress. These findings emphasize that broadening the community-health lens to consider the upstream factor of SES when preparing health promotion interventions is essential to achieving health equity for vulnerable populations
