Project description:PurposeUnderage drinking is strictly prohibited by law, nevertheless, adolescents report having access through social supply from family, friends and other members of the society. The aim of this study was to determine the primary suppliers of alcohol to Korean teenagers.DesignCross-sectional study.SettingData were collected from 21 high schools in geographically diverse regions in South Korea from June to July 2012 as part of the International Alcohol Control Study.ParticipantsData were analysed from 247 high schoolers aged 16-18 years old as part of the International Alcohol Control Study.Primary and secondary outcome measuresSocial supply to high school students.ResultsMore than 56% of high schoolers who participated in the International Alcohol Control Survey had been supplied alcohol at least once. Of this number, approximately 59% were males. Parents (especially fathers) and friends were the main suppliers, with friends contributing greater volumes (205 g) of alcohol. Of the number of students provided by mothers, 52% of them were females while 73% of respondents provided by friends were males. The most significant place for alcohol supply was at special events. Males were at higher odds for risky drinking.ConclusionsThese results support previous findings about the role of parents and friends in underage drinking in South Korean high school drinkers.

Project description:IntroductionExtant studies have examined the effect of psychological characteristics on clinical features that define behavior problems. The purpose of this study was to analyze the effects of temperament and character as both individual factors and complex profiles on behavior problems in a community sample of adolescents.MethodsBehavior problems and personality of 670 Korean high school students were measured with the Youth Self-Report (YSR) and Junior version of the Temperament and Character Inventory (JTCI). Stepwise regression analysis analyzed the effects of JTCI character and temperament traits on YSR Total, Internalizing and Externalizing subscale scores, and Profile Analysis examined differences of JTCI personality profiles among three latent YSR subscale profiles acquired from Latent Profile Analysis.ResultsSeven subscales of the JTCI explained 38% of the YSR total degree of behavior problems, and JTCI Novelty-Seeking and Harm-Avoidance were found to account for vulnerability while JTCI Reward-Dependence and Self-Directedness explained resilience to behavior problems. There were three distinct latent YSR profile groups based on nine YSR subscales, and low behavior problem group showed a resilient personality profile characterized by low Novelty-Seeking and Harm-Avoidance and high Reward-Dependence, Persistence, Self-Directedness and Cooperativeness while high behavior problem group exhibited a vulnerable personality profile of the opposite tendency.DiscussionTemperament and character explained behavior problems of Korean high school students as both individual personality traits and a complex personality profile. The results and implications of this study were examined in regard to mental health of adolescents, and the importance of education in the development of mature personality are discussed.

Project description:AbstractChronic diarrhea and constipation are common in adolescents and are associated with depression and anxiety. However, the association was not reported in adolescents adjusted for other psychological factors (resilience, personality traits, perceived stress, and suicidal ideation). Therefore, we investigated the significant psychological factors predicting chronic diarrhea and constipation in adjusted individuals for co-variables.A total of 819 Korean high school students who completed bowel health and psychological questionnaires were enrolled in this study. Depression and anxiety were assessed using validated questionnaires. We used multivariate analyses, controlling for demographic, dietary, lifestyle, and psychological variables to predict chronic diarrhea and constipation.Chronic diarrhea and constipation were more common in individuals with depression (22.3% and 18.6%, respectively) than in individuals with no depression (7.0% and 10.9%, respectively). In addition, they were more prevalent in individuals with anxiety (24.5% and 18.6%, respectively) than in individuals with no anxiety (9.1% and 12.7%, respectively). Multivariate analyses showed that resilience (adjusted risk ratio [aRR] = 0.98, adjusted 95% confidence interval [CI] = 0.97-0.99), moderate (aRR = 6.77, adjusted 95% CI = 3.55-12.91), and severe depression (aRR = 7.42, adjusted 95% CI = 3.61-15.27) were associated with chronic diarrhea. Only mild depression was associated with chronic constipation (aRR = 2.14, adjusted 95% CI = 1.36-3.38). However, anxiety was not significantly associated with chronic diarrhea or constipation.Among the psychological factors predicting disordered bowel habits, resilience and moderate and severe depression were significant predictors of chronic diarrhea, but not anxiety. Furthermore, only mild depression was an independent predictor of chronic constipation.

Project description:Objective: This study aimed to contribute to understanding the mechanisms underlying the association between empowering motivational climate in physical education and social responsibility among high school students, and have important implications for interventions aimed at improving social responsibility among high school students. Methods: Through the quota sampling, 802 students (average age = 17 years, SD = 0.97 years) that complied with the requirements were surveyed from Anhui Province in China. Empowering motivational climate in physical education, social responsibility, interpersonal disturbance, and general self-efficacy were assessed using standard scales. For data analysis, Pearson's correlation analysis, structural equation model test, and bias-corrected percentile Bootstrap method were carried out in turn. Results: (1) Common method biases can be accepted in this study, and the correlation among empowering motivational climate in physical education, social responsibility, interpersonal disturbance, and general self-efficacy are all significant; (2)Empowering motivational climate in physical education, interpersonal disturbance and general self-efficacy can all predict social responsibility significantly; (3) Structural equation modeling indicates good fit: χ2/df = 2.86, RMESA = 0.068, CFI = 0.92, NNFI = 0.91, NFI = 0.90, GFI = 0.93. It indicates that interpersonal disturbance and general self-efficacy can play mediating roles between empowering motivational climate in physical education and social responsibility, respectively. After that, interpersonal disturbance as well as general self-efficacy in turn plays the chain mediating effect in the relationship between empowering motivational climate in physical education and social responsibility. The effect size of the mediating effect of interpersonal disturbance and general self-efficacy in the relationship between empowering motivational climate in physical education and social responsibility is 0.048 and 0.148, respectively, and the effect size of the chain mediating effect is 0.031. Conclusion: Empowering motivational climate in physical education not only has a direct effect on social responsibility among high school students, but also influences social responsibility by the chain mediating effect of interpersonal disturbance and general self-efficacy.

Project description:Treating social problem-solving as a construct comprised of a number of components enables us to examine patterns formed by the components. However, variable-centered research has paid little attention to exploring these patterns to date. A person-centered approach may enable us to identify distinct profiles for groups. Our study aimed to investigate whether it is possible to establish homogeneous profiles for groups based on social problem-solving factors (positive and negative orientation, rationality, impulsivity, and avoidance). Furthermore, the study sought to explore whether there is any difference among these groups regarding self-efficacy, a fundamental component of social problem-solving. We used cluster analysis to examine social problem-solving and self-efficacy among 543 Hungarian secondary school students and 277 Hungarian university students. We identified three homogeneous groups that had shared characteristics in the two age samples (optimistic–hasty; optimistic–reflective; resigned–procrastinator). Four further groups were identified among adolescents (resigned–distancer; insecure–reflective; insecure–hasty; resigned–brooder); and an additional three among young adults (optimistic–modest; tense–hasty; tense–reflective). The relationships among the social problem-solving factors and self-efficacy differed among the profiles. Taking into account the profiles explored in this study may help identify groups that need improvement, and contribute to interventions being better suited to the needs of a particular group.

Project description:The prevalence of latnet Mycobacterium tuberculosis infection (LTBI) in the first-grade high school students in South Korea was 2.1%, which was the lowest level at congregated settings in 2017. For LTBI cases refusing anti-tuberculosis (TB) medication or having poor compliance, additional support should be considered. Eight systematic reviews concluded that vitamin D (VD) deficiency is a risk factor for TB. While three of four South Korean adolescents were VD deficiency, VD supplementation could be a practical remedy to protect LTBI students of refusing anti-TB medication or having poor compliance.

Project description:ObjectiveTo investigate whether later high school start time is associated with lower migraine frequency in high school students with migraine.BackgroundAdequate sleep is thought to be important in managing adolescent migraine. The American Academy of Sleep Medicine recommends teenagers sleep ≥8 hours/night. Adolescents have a physiologically delayed sleep phase, going to bed, and waking later than children and adults. The American Academy of Pediatrics (AAP) accordingly recommends high schools start no earlier than 8:30 AM.MethodsCross-sectional observational study of U.S. high schoolers with migraine. Participants were recruited nationally using social media. Respondents attending high schools starting at 8:30 AM or later were compared to those attending earlier start time schools. The primary outcome was headache days/month.ResultsTwo hundred and fifty-six subjects constituted the analysis set: 115 later group vs 141 earlier group. Age and sex did not differ. Mean (SD) self-reported headache days/month were 7 (5) vs 8 (7), respectively, (P = .985); mean difference (95% CI for the difference) was -0.8 (-2.3-0.7) days. Median (IQR) self-reported total hours of sleep/school night were: 5.6 (5.0-6.6) vs 5.6 (4.5-6.4), P = .058. Students attending later start time schools woke later (median [IQR] 6:38 AM [55 minutes] vs 6:09 AM [59 minutes], P < .0001) and left home later (median [IQR] 7:28 AM [28 minutes] vs 7:02 AM [60 minutes], P < .0001). Average commute time was also longer: 41 (21) minutes vs 28 (16), P < .0001. The vast majority in both groups reported missing breakfast at least once/week: 103/114 (90.4%) vs 128/141 (90.8%), P = .907. Hours of sleep did not correlate with headache days per month.ConclusionHigh school start time does not have a large effect on headache frequency in high schoolers with migraine. Given the high variance in headache days/month observed in this study, a larger study would be needed to determine whether there might still be a small effect of starting high school at/after 8:30 AM. More research is needed to establish evidence-based recommendations about lifestyle factors in adolescent migraine management.

Project description:Face-to-face contacts between individuals contribute to shape social networks and play an important role in determining how infectious diseases can spread within a population. It is thus important to obtain accurate and reliable descriptions of human contact patterns occurring in various day-to-day life contexts. Recent technological advances and the development of wearable sensors able to sense proximity patterns have made it possible to gather data giving access to time-varying contact networks of individuals in specific environments. Here we present and analyze two such data sets describing with high temporal resolution the contact patterns of students in a high school. We define contact matrices describing the contact patterns between students of different classes and show the importance of the class structure. We take advantage of the fact that the two data sets were collected in the same setting during several days in two successive years to perform a longitudinal analysis on two very different timescales. We show the high stability of the contact patterns across days and across years: the statistical distributions of numbers and durations of contacts are the same in different periods, and we observe a very high similarity of the contact matrices measured in different days or different years. The rate of change of the contacts of each individual from one day to the next is also similar in different years. We discuss the interest of the present analysis and data sets for various fields, including in social sciences in order to better understand and model human behavior and interactions in different contexts, and in epidemiology in order to inform models describing the spread of infectious diseases and design targeted containment strategies.

Project description:We present a laboratory experiment that introduces high school chemistry students to microfluidics while teaching fundamental properties of acid-base chemistry. The procedure enables students to create microfluidic systems using nonspecialized equipment that is available in high school classrooms and reagents that are safe, inexpensive, and commercially available. The experiment is designed to ignite creativity and confidence about experimental design in a high school chemistry class. This experiment requires a computer program (e.g., PowerPoint), Shrinky Dink film, a readily available silicone polymer, weak acids, bases, and a colorimetric pH indicator. Over the span of five 45-min class periods, teams of students design and prepare devices in which two different pH solutions mix in a predictable way to create five different pH solutions. Initial device designs are instructive but rarely optimal. During two additional half-class periods, students have the opportunity to use their initial observations to redesign their microfluidic systems to optimize the outcome. The experiment exposes students to cutting-edge science and the design process, and solidifies introductory chemistry concepts including laminar flow, neutralization of weak acids-bases, and polymers.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) vaccination is expected to end the pandemic; a high coverage rate is required to meet this end. This study aimed to investigate the prevalence of behavioral intention of free/self-paid COVID-19 vaccination and its associations with prosociality and social responsibility among university students in China.MethodsAn anonymous online cross-sectional survey was conducted among 6922 university students in five provinces in China during November 1-28, 2020. With informed consent, participants filled out an online survey link distributed to them via WeChat study groups. The response rate was 72.3%.ResultsThe prevalence of behavioral intentions of free COVID-19 vaccination was 78.1%, but it dropped to 57.7% if the COVID-19 vaccination involved self-payment (400 RMB; around 42 USD). After adjusting for background factors, prosociality (free vaccination: adjusted odds ratio [ORa] = 1.10, 95% CI: 1.09-1.12; self-paid vaccination: ORa = 1.08, 95% CI: 1.07-1.09) and social responsibility (free vaccination: ORa = 1.17, 95% CI: 1.14-1.19; self-paid vaccination: ORa = 1.13, 95% CI: 1.11-1.14) were positively associated with the two variables of COVID-19 vaccination intention.ConclusionThe present study demonstrated the positive effects of prosociality and social responsibility on the intention of COVID-19 vaccination. Accordingly, modification of prosociality and social responsibility can potentially improve COVID-19 vaccination. Future longitudinal and intervention studies are warranted to confirm such associations across populations and countries.
