RESUMEN

Introduction: Physical inactivity and mental health disorders are emerging threats to public health in China. Previous research on links between exercise and mental wellbeing have focused on clinical populations, with little evidence from the general population, particularly younger adults. We aimed to investigate associations between physical fitness and mental health in Chinese college students. Methods: In this series, of cross-sectional observational studies, we enrolled 7,468 Chinese college students aged 16-24 years in 199 classes at Changzhou Vocational Institute of Engineering between Sept 1, 2017, and Jun 30, 2018. Exposures of interest were the students' physical fitness level, measured by the Chinese University Students Physique Test. The primary outcomes were mental health situations, measured by the University Personality Inventory (UPI). The multivariable linear regression models were used to assess the relationship between the levels of physical fitness and mental disorders symptoms. Results: Completed mental health and physical fitness data were available for 6,724 participants aged 16-24 years. Compared with the failed group, the corresponding levels of difference in overall UPI scores were - 1.45 scores (95% CI: -2.45, -0.46; p < 0.01) for the passed group and - 2.95 scores (95% CI: -4.13, -1.77; p < 0.01) for the good group. Similar results were observed in the four different aspects of psychotic disorder symptoms. Discussion: There was a significantly negative correlation between the level of physical fitness and phycological situations among Chinese college students. Our findings highlight the psychological situations of students with low physical fitness levels should be concerned.

RESUMEN

Objectives: Increasing dependence on smartphones results in the appearance of psychological problems, especially among young people. This study aims to determine the rates of alexithymia and its relationship with smartphone addiction and psychological distress in university students. Methods: A total of 2616 students (mean age = 22.5±3.5 years; 73.1% female) from universities in Egypt, Oman, and Pakistan were included in a cross-sectional and comparative study conducted through a web survey during the COVID-19 pandemic from October to December 2021. The following scales were used: Toronto Alexithymia Scale (TAS-20), Depression Anxiety Stress Scale (DASS-21), and Smartphone Addiction Scale-Short Version (SAS-SV). The survey also included questions related to sociodemographic and smartphone usage patterns.

RESUMEN

Background: Chinese youth are at high risk for depression with a significantly higher detection rate of depression risk than other age groups, which brings about a huge challenge to the mental health work of universities. Developing supportive resources that promote resilience against adverse environmental influences in high-risk groups is quite more urgent than medical treatment for firm diagnoses of mental issues that have developed into depression in the current background. Methods: A total of 665 university students in China completed self-reported questionnaires measuring psychological resilience, social support, and coping styles. The structural equation model testing on the goodness of fit of the theoretical framework was first performed. Descriptive statistics and Pearson's correlation analysis among social support, resilience, and coping styles were then conducted. At last, we tested the mediating role of coping styles. Results: Social support has a significant positive effect on the psychological resilience of the youth. Mixed coping and immature coping styles have significant negative impacts on both social support and resilience, while mature coping styles have a significant positive effect on social support and resilience. Mature and immature coping styles mediate the association between social support and resilience in youth. Conclusion: Based on stress theory, this study explores mechanisms that facilitate the development of resilience in young people with regard to social support and coping styles. The current research depicts an interventional perspective of building a social support network that guides the youth to adopt mature coping styles to enhance their resilience and facilitate their mental health.

RESUMEN

Objectives: This study aimed to describe the trends of the muscle-strengthening exercise (MSE) guidelines adherence in adolescents and factors associated with the adherence. Methods: Using the Youth Risk Behavioural Survey data, this study assessed the trends of adhering to the MSE guidelines in adolescents. The survey-year-based trends of MSE guidelines adherence was assessed with logistic regression. Binary logistic regression was used to identify the correlates (i.e., sex, grade, race/ethnicity) of the guidelines' adherence. Results: 73,074 study participants (female = 36,497, male = 36,108; mean age = 16.04 years) were included for analysis. An overall declining trend of the MSE guidelines in adolescents was found (55.6% in 2011 → 49.5% in 2019, p < 0.001), and similar trends were observed in both sexes. The declining trends varied by sociodemographic factors (e.g., grade). Boys and younger adolescents were more likely to adhere to the MSE guidelines. Conclusion: The declining trend of adhering to MSE guidelines in US adolescents would be a health concern in this population. Girls and older adolescents should be targeted as intervention priorities.

RESUMEN

Background: Previous studies have focused on the opposite relation between muscle strength, obesity, and depression in adults. Moreover, the evidence has indicated that obesity and depression in adults might be significantly decreased with Muscle Strength Exercise (MSE) albeit it might be insufficient. Therefore, the current study aimed to investigate the association between MSE, adiposity, and depression among United States adolescents. Materials and methods: This cross-sectional study used the Youth Risk Behavioral Survey (YRBS) data. In YRBS, a cluster sample was used, and the investigation was divided into three stages. The study surveyed 13,677 high school students and conducted self-reported questionnaires on sex, grade, race/ethnicity, MSE days, overweight, obesity, and depressive symptoms. The study got the nationally representative population of American students in Grade 9 to 12 (around 12-18 years). Results: A total of 13,677 participants (female = 6,885, male = 6641) were included in the final analysis. The participants meeting the guidelines' requirements seemed more likely to be obese than those not meeting (OR = 1.28, 95% CI = 1.06-1.55). There was no statistical significance in the relations between the MSE guidelines and overweight and depression (OR = 0.86, 95% CI = 0.73-1.01: OR = 0.94, 95% CI = 0.83-1.06). For all the participants, the prevalence of those conforming to MSE was 30.1%. One-fifth of the participants reported no MSE per week, 7.8% reported 3 days of MSE per week, and 7.7% reported 7 days. Conclusion: The main finding of this study indicated a positive relationship between the normative MSE required in guidelines and low-level obesity. Beyond that, the evidence was insufficient to confirm the positive links between MSE and depression among American adolescents. Our study could offer evidence for future MSE interventions in adolescents.

RESUMEN

The first wave of the COVID-19 pandemic has led to extreme global consequences. In this paper, changes in the basic segments of students' everyday life and their subjective perception are investigated. The research was conducted in Croatia, Serbia and Slovenia. The application of the mixed method was performed to provide breadth and depth of understanding of students' responses to lifestyle changes. The research was conducted in two phases: a quantitative, using an online survey (N = 1,053), from April 15th to April 28th 2020, and a qualitative, using semi-structured interviews (N = 30), from June 10th to July 27th 2020. Students showed similar responses to the measures, but it turned out that the response in that population was different when their gender and study program were taken into account. The results suggest that students of study programs that are not "health-related" were more sensitive to change in habits than students of "health-related" study programs, but generally changes are visible in sleep patterns (going to bed late and waking up 60 to 80 min earlier). At the same time, the time spent in front of screens increased, from M = 4.49 (SD = 2.72) hours to M= 8.27 (SD = 3.44) hours during Covid-19, not only due to the transition to e-learning, but also due to a "stay at home" measure. Furthermore, students were less physically active, there was a decrease in exercise by 20 min (SD = 86.52) and a decrease in walking (M = 54 min, SD = 103.62) per day, and what is positive is that they were able to maintain the recommended amount of physical activity. The research contributes to the understanding of social consequences of extraordinary measures in students as young, healthy and highly educated social actors, as well as deeper insight into everyday strategies they undertake to counter or adapt to the new situation.

RESUMEN

Objective: The purpose of this research was to investigate the prevalence of lifestyle behaviors and suicide-related behaviors and the association between them using a nationally representative sample of adolescents from the USA. Methods: 13,677 high school students aged 14-18 years were included in this cross-sectional study. The research data were retrieved from the Youth Risk Behavior Surveillance System Survey in 2019. All data on age, sex, grade, race, physical activity, television time, fruit intake, and suicide-related behavior were self-reported by students. Logistic regression models were adopted to examine the association between lifestyle behaviors and the suicide-related behaviors. Results: Students who played video/computer games for ≥2 h had higher risk of suicide attempt (OR = 1.55, 95%CI: 1.30-1.85). Daily sleep duration of ≤8 h was positively associated with considering a suicide attempt (OR = 1.99, 95%CI: 1.62-2.43). In addition, participants who did not engage in any sport team were more likely to report considering a suicide attempt (OR = 1.50, 95%CI: 1.24-1.81). Conclusion: This research suggests that some lifestyle behaviors (e.g., time for video or computer use, sleep duration, sports team participation, regular breakfast intake, and substance use) are associated with increased risk of suicidal behavior and ideation in high school students. To identify the specific effect of multiple lifestyle factors in influencing the risk of suicide-related behaviors in high school students, longitudinal studies are warranted in future.

RESUMEN

To address the need for a valid and reliable scale of youth leadership potential based on the development theory of leadership, the current study developed the Youth Leadership Potential Scale (YLPS) and investigated its factor structure and psychometric properties in a sample of 696 students (grades 7-9) in China. Exploratory structural equation modeling (ESEM) identified a five-factor solution comprising leadership information, leadership attitude, communication skills, decision-making skills, and stress management skills. ESEM within confirmatory factor analysis demonstrated an adequate fit for this structure. The scale showed good composite reliability and measurement invariance across different gender and grade/age groups. The scale also showed sufficient concurrent validity with the Coping Self-Efficacy Scale, the Chinese Roets Rating Scale for Leadership, and the Leadership Skills Inventory. Furthermore, criterion-related validity was supported by the relationship between YLPS scores and the length of student leadership positions. The results suggest that the YLPS is a valid and pragmatic measure for assessing youth leadership potential. The current study is the first to develop a youth leadership potential scale based on the development theory of leadership.

RESUMEN

BACKGROUND: Indian society is considered to have conservative attitudes regarding sex and is ambivalent about the concept of sex education. Previous reports suggest that a considerable proportion of Indian youth have inadequate sexual knowledge and hold a variety of sexual misconceptions. Methodological flaws limit the generalizability of some earlier studies. AIMS: This study assessed knowledge and attitude toward sexual health and common sexual practices among college students in Tamil Nadu. METHODOLOGY: A total of 952 students from seven randomly selected colleges in Vellore district of Tamil Nadu participated in the survey. The survey questionnaire contained 51 questions on knowledge and attitude toward sexual health and common sexual practices and incorporated items from standardized questionnaires and additional questions suggested by a multidisciplinary group who work in the field. RESULTS: Two hundred seventy-five students among those who completed the survey were women. Higher knowledge scores were associated with older age, male gender, being from a rural background, pursuing non-science streams, and being in postgraduate courses. Nonconservative attitudes were associated with older age, male gender, enrollment in non-science disciplines, discomfort with the family environment, and a religious family background. CONCLUSIONS: Sexual knowledge is inadequate and sexual misconceptions were widely prevalent in the population studied. School-based comprehensive sex education programs, which have been demonstrated to be effective in improving sexual health, could be used to deal with these lacunae in sexual health knowledge and attitudes.

RESUMEN

The sexually transmitted infections are an actual medical social problem of the youth that negatively impacts natality because of high proportion in the structure of causes of infertility and miscarriage. The questionnaire survey was carried out on the sampling of 938 pupils and students of natural science and humanitarian specialties. It is established that those of acquiring natural science education in the issues related to sexually transmitted diseases more often trust professional sources of information (physicians and scientific publications) while humanitarians prefer Internet and social advertising. The profile of education has no impact on self-evaluation of possible infection, readiness to screening examination and visiting the physician in case of corresponding problems occurrence.

RESUMEN

BACKGROUND: In general psychiatric services, cost-benefit screening instruments for psychopathic traits in adolescents are needed. The aim of the present study was to study the psychometric properties of the Finnish versions of the Youth Psychopathic traits Inventory (YPI) and the Antisocial Process Screening Device (APSD-SR) in community youth. As gender-specific differences exist in psychopathic traits, we analyzed the data separately in girls and boys. METHODS: The YPI and the APSD-SR were administered to 372 9th graders (174 boys and 198 girls) with a mean age of 15.06 years (SD 0.28). Cronbach's alphas were used to study internal consistency. The factor structures of the self-assessments were studied using both Confirmatory Factor Analysis (CFA) and Principal Component Analysis (PCA). RESULTS: In both self-assessments, boys scored significantly higher in the total scores, Interpersonal and Affective dimension scores as well as in most sub-dimensions. In the YPI, the alpha values for total and dimensional scores ranged from 0.55 to 0.91 in boys and from 0.74 to 0.89 in girls and, in the APSD-SR, respectively, from 0.38 to 0.78 and from 0.29 to 0.78. In CFA, the three-factor model produced poor fit for both self-assessments. For the ten sub-dimensions of the YPI, the PCA suggested two factors. Extending the model into three components showed sub-dimension loadings according to the original dimensions. For the APSD-SR, the PCA revealed a five-factor structure in the male sample and a six-factor one in the female group. When limiting the model to a three factor- model, we obtained a structure, which resembled the original dimensions. CONCLUSIONS: Both the YPI and the APSD-SR are promising tools of screening for psychopathic features in Finnish community youth. The YPI turned out to be slightly better than the APSD- SR in both reliability and factor structure. However, the original three-factor models did not find support. Both self-assessments were somewhat weak for tapping the callous-unemotional traits of the psychopathic character, but, again, the YPI worked better than the ASPD-SR. Both self-assessments revealed significant gender differences in psychopathic character traits.

RESUMEN

Objective To explore the variations and prognostic factors of hyperhomocysteinaemia in ischemic cerebral apoplexy for the youth who administrated vitamin B6,vitamin B12 and folic acid at pretherapy and post-treatment.Methods One hundred and twenty cases of young patients with ischemic cerebral apoplexy in the Pinggu Hospital of Capital University from January 2003 to December 2013 as case group(intervention group,60 cases and 60 cases of non-intervention group),while 120 youth volunteers with the same period and age without neurological diseases as a control group.Both groups patients were detected for hyperhomocysteinaemia,folic acid and vitamin B12.The non-intervention group was administrated basic treatment,while the intervention group administrated vitamin B6,vitamin B12 and folic acid on this basis.The hyperhomocysteinaemia,folic acid and vitamin B12 were detected repetitively after four weeks.Results Compared with control group,the hyperhomocysteinaemia in ischemic cerebral apoplexy group for the youth had increased significantly ((10.2 ± 3.1) μmmol/L vs.(21.3 ± 4.5) μmmol/L,P ＜ 0.05).The hyperhomocysteinaemia,folic acid and vitamin B12 had no significant differences between intervention group and non-intervention group (P ＞ 0.05).After replenished vitamin B6,vitamin B12 and folic acid,the hyperhomocysteinaemia had decreased significantly ((10.5 ± 3.0) μmnol/L) in intervention group.Folic acid ((6.5±2.8)μg/L) and vitamin B12(450.2±155.6) ng/L) had increased significantly(P＜0.05).Conclusion The hyperhomocysteinaemia increased in ischemic cerebral apoplexy for the youth.It is that hyperhomocysteinaemia decreased by replenished vitamin B6,vitamin B12 and folic acid which make for prognosis in ischemic cerebral apoplexy for the youth.

RESUMEN

The purpose of this study was to investigate risk factors that could promote HIV infection amongst adolescents and young adults living in tertiary educational institutional hostels in Namibia. Employing structured questionnaires and focus group discussions, we sought to answer questions pertaining to factors, beliefs systems, values, traditions and sexual relations that could promote HIV infection in the student hostels. The data on these issues were gathered from 306 male and 314 female students aged 18-35 years living in eight hostels. Amongst other results, the data revealed that sexual promiscuity in the hostels was treated as the norm in the majority of cases, unauthorized access to hostel rooms by non-hostel dwellers was rampant, sexual harassment of female students by men who were under the influence of alcohol was reported to be common and there was general lack of support for victims of sexual abuse in the hostels. In addition, there was a general sense of insecurity in the hostels where more than 50% of the participants were afraid of being sexually attacked, some female hostel residents engaged in sexual activities for monetary and material gain and there was a general practice of older men from the community having sexual relations with young female hostel dwellers. To mitigate these and other risks it is recommended that there be provision of more HIV/AIDS prevention services, enhanced security, non-toxic entertainment (e.g. participation in sport and social clubs) and the banning of the sale of alcohol in student residences and on tertiary institution campuses. These and other results are discussed in the article and ways of mitigating the risks are proposed.

RESUMEN

O estudo analisa aspectos macro e micro estruturais das parcerias mantidas pelas organizações do Consórcio Social da Juventude em Salvador - CSJ/RMS. A noção "redes sociais" é utilizada como ferramenta teórico-metodológica e como articulações para efetivar projetos sociais. O instrumento abrangeu questões de mapeamento da rede, recursos trocados e impactos para desempenho organizacional. Delinearam-se dois níveis de análise: Rede Geral, parcerias entre diversos setores, e Rede Consórcio, parcerias entre integrantes do CSJ. A Rede Geral apresentou-se totalmente interconectada e existem conectores centrais externos ao CSJ exercendo papel de suporte financeiro. A Rede Consórcio apresentou-se fragmentada; com baixa densidade nas relações; alta concentração de poder ou dependência em atores específicos; percepção de impacto no desempenho nas organizações com mais parcerias. Este trabalho evidencia a complexidade dos arranjos institucionais nas ações sociais, os impactos dos padrões de articulação no CSJ e nas organizações e o potencial investigativo da teoria de Redes Sociais.

The notion of social networks is used as a theoretical and methodological tool and associative arrangements to social projects. The survey covered questions about network mapping, exchanged resources and impact to the organizational performance. Two level of analysis were outlined: the General Network and the Youth Social Partnership Network . The General Network proved to be totally interconnected there being connectors external to CSJ performing financial support role. The Youth Social Partnership Network proved to be fragmented, with low density, high power concentration or dependence on actors, perception of the impact to the performance of the organizations with more connections. This work makes clear the complexity of the institutional arrangements in the social actions and the investigative potential of the theory Social Network.
