The Youthful Ties That Bind

LAST month, hundreds of African and Chinese youth leaders descended on Beijing. Xhey had already met once before in Windhoek, Namibia＇s capital. One year later, they convened again to discuss new issues at the Second Africa-China Young Leaders Forum, which ran between June 18 and 19.

Numerical simulation of landscape evolution and mountain uplift history constrain——A case study from the youthful stage mountains around the central Hexi Corridor,NE Tibetan Plateau

Landscape evolution models(LEMs)are essential tools for analyzing tectonic-climate interactions and reproducing landform-shaping processes.In this study we used a LEM to simulate the evolution of the mountains from the central Hexi Corridor in the northeastern Tibetan Plateau,where the climate is arid and the surface processes are relatively uniform.However,there are pronounced differences in the topography between the mountains around the central Hexi Corridor.The East Jintanan Shan,West Jintanan Shan and Heli Shan are located in the northern part of the corridor;and the Yumu Shan in the southern part.Firstly,several representative areas were selected from these mountains to analyze the topographic characteristics,including the uniform valley spacing,local relief,and the outlet number.Secondly,a LEM for these areas was constructed using the Landlab platform,and the landscape evolution was simulated.With uniform valley spacing and other topographic characteristics as the criteria,we compared the realistic and simulated terrain for different model ages.Finally,based on the similarity of the simulated and realistic terrain,we estimated the timing of the initial uplift and the uplift rate of the four mountain ranges.The results are consistent with previous geological and geomorphological records from these youthful stage mountains that have not yet reached a steady state.Our findings demonstrate that LEMs combined with topographic characteristics are a reliable means of constraining the timing of the initial uplift and the uplift rate of the youthful stage mountain.Our approach can potentially be applied to other youthful stage mountains and it may become a valuable tool in tectonic geomorphology research.

Global prevalence and gender inequalities in at least 60 min of self-reported moderate-to-vigorous physical activity 1 or more days per week:An analysis with 707,616 adolescents

Background:Guidelines recommend that adolescents should accumulate an average of 60 min per day of moderate-to-vigorous physical activity(MVPA).However,using only this cut-off could hide important information.For instance,from a population-level point of view,increasing physical activity for those with no or low physical activity could provide more health benefits than increasing physical activity for those with intermediate levels.Also,including a more sensitive cut-point of≥1 days per week could be an additional strategy for identifying those with low access/opportunities for physical activity practice.Thus,the current study aims to estimate the prevalence of≥60 min of MVPA≥1 days per week among adolescents globally,and to describe any relevant gender inequalities.Methods:We used representative datasets from 146 countries/territories collected between 2003 and 2019.MVPA was self-reported.Participants were grouped into younger(≤14 years old)and older(>14 years old)adolescents.Crude Poisson regression models were used to identify the relative differences in≥60 min of MVPA≥1 days per week between boys and girls,and random-effects meta-analysis models were used to identify the pooled estimates.Analyses were stratified by country and region.Results:Approximately 80%of both younger and older adolescents reported≥60 min of MVPA≥1 days per week.This prevalence was≥94%in Europe and Central Asia and North America,while the estimates for the other regions were<77%.The prevalence of≥60 min of MVPA≥1 days per week was higher among boys than girls,with the largest differences occurring among the oldest adolescents(Prevalence ratio_(≤14y)=1.04(95%confidence interval(95%CI)):1.03-1.04)vs.Prevalence ratio_(>14y)=1.09(95%CI:1.08-1.10)).Conclusion:Approximately 8 out of 10 adolescents reported accumulating≥60 min of MVPA≥1 days per week,with notable differences between regions.Gender differences were observed in several countries,especially among the oldest adolescents.Priorities for physical activity promotion among adolescents should include increasing access/opportunities for physical activity among those who do not achieve≥60 min of MVPA≥1 days per week and reducing gender inequalities.

Exploring the Reasons for Selfie-Taking and Selfie-Posting on Social Media with Its Effect on Psychological and Social Lives:A Study among Indian Youths

‘Selfie’taking was introduced to the common people by smartphones and has become a common practice across the globe in no time.With technological advancement and the popularity of smartphones,selfie-taking has grown rapidly within a short time.In light of the new trend set by the generation,this study aimed to explore reasons for selfie-taking and selfie-posting on social media and their effects on the social and psychological lives of young adults.A purposive sampling method was adopted to select 20 Indian citizens,between 18 and 24 years.The data were collected through semi-structured interviews and analysed using thematic analysis.Selfie-taking and posting on social media give positive feelings,and it acts as a mood modifier dependent mostly on the favourability and feedback about the post which in turn affects emotions and self-satisfaction.

Determinants of Modern Contraceptive Uptake among the Youth in Akuse Township in the Lower Manya Krobo Municipality, Ghana

Background: Access to safe and effective contraception is crucial for sexual and reproductive health to be at its best. This allows improved pregnancy results and the avoidance of unintended births. Teenagers’ views on using contraceptives are influenced by the information available at their disposal. The study assessed the influential factors affecting the utilization of modern contraceptives among the youth in Akuse in the Eastern Region of Ghana. Methods: The data for the study were gathered from 378 consented youth aged 15 - 24 years using a quantitative cross-sectional study design and a well-structured questionnaire. Person’s Chi-Square test was adopted to measure the association between the outcome variable and selected independent variables. Logistic regression models were utilized to measure the odds of the factors influencing modern contraceptive use among the respondents. Results: The results of the study suggested a high knowledge level of contraceptives;however, the prevalence of utilization was low. The level of education and age were factors found to influence the uptake of contraceptives. A bivariate analysis to examine the association between selected socio-demographic variables revealed that educational level (p = 0.044), religious affiliation (p = 0.002), and ethnicity (p = 0.016) were statistically associated with modern contraceptive use among the respondents. All other tested demographic variables including the age groups, gender, marital status, and residential status proved otherwise at the observed p-values greater than the 0.05 threshold. Respondents who indicated staying with partners were 6.79 times more likely to use contraceptives compared to their counterparts staying with a parent, after controlling for all other covariates. Conclusions: Based on the findings of this study, it was concluded that high contraceptive knowledge influences the choice of contraceptive preferred by the youth, and contraceptive use is also influenced by the advancement in age and educational level of the youth. It is however recommended that parents, guidance, and teachers be entreated to offer relevant and timely sexual information or education as these will most likely improve the uptake of modern contraceptives among the targeted population.

Muscle Mass Is Associated with Depression in Adolescents and Young Adults

Background and Aims: The study aims to explore the association between body composition and depression in adolescents and young adults. Methods: A random cluster sampling method was used to select 41 age-matched indi-viduals (aged 11 - 30) as a non-depressive control group. The Department of Psychology at the Affiliated Hospital of Youjiang Medical University for Na-tionalities recruited 27 depressive patients within the same age range. Bioelec-trical impedance analysis measured body composition, while SCL-90, SAS, and SDS were employed for depression diagnosis. Logistic regression analysis was conducted to assess the relationship between body composition and de-pression scores. Results: The Depression Group exhibited higher levels of fat mass (p Conclusion: Depression is associated with age, gender, and muscle mass in adolescents and young people. Proper exercise and a healthy diet can increase muscle mass, thereby reducing fat mass and, as a result, reducing the prevalence of depression.

The Youth’s View of Marriage in Chinese Mainstream Media Discourse-A Corpus-assisted Three-dimensional Discourse Analysis

The rising of aging and the declining of birth rates have forced the public to focus on the youth’s view on marriage.Based on critical discourse analysis and combined with Fairclough’s three-dimensional discourse analysis model,this paper builds a“Chinese media News Report Corpus on the topic of‘marriage’”whose news are collected from China Daily.It is found that the discourses are neutral and objective with regard to the advantages and disadvantages of marriage,but in general,it is still a traditional view of marriage that is inevitable and closely related to fertility.Although this is controlled by the policies and the social reasons including declining fertility rate,it deviates from the current view of the youth towards marriage,resulting in many serious consequences such as young people’s rejection.In addition,this research found that male and female have great differences in their views on marriage,and men’s resistance to marriage is far greater than that of women,which is departure from the public’s cognition.The reasons behind this need to be explored in order to solve the marriage and love problems of young people in today’s era and realize the healthy development of young marriage.

Cultivating Youth Interest in Badminton

Conducting an investigation and analysis using literature review methods,the current state of interest cultivation among young badminton players was examined.The findings indicate a less optimistic situation regarding interest development among these young athletes:the initial interest motivation of young badminton players is significantly influenced by parents,with parental focus more on sporting achievements than the child’s happiness,neglecting the emotional well-being of children;coaches prioritize fundamental technical skills over interest cultivation,and the methods used to stimulate interest still exhibit traditional tendencies,overlooking the application of game-based and competitive approaches;there is a lack of practical implementation in interest cultivation;the majority of coaches create an unfavorable classroom atmosphere,easily overlooking students’emotional experiences.Understanding the current development status and trends in interest cultivation for youth badminton,this study analyzed data on interest cultivation methods.It was found that the majority of badminton teaching tends to focus on scientific technical training and physical fitness for young players.While many coaches and parents express affirmation for interest cultivation methods,they are not widely applied in practice at present.Incorporating game-based teaching into badminton instruction has the potential to enhance students’interest in badminton learning,especially for novice young players,facilitating the early establishment of a love for badminton.

Challenges and Countermeasures of Youth Moral Education in the Era of Big Data

Youth moral education is an extremely important work,which is related to the inheritance of traditional virtues of the Chinese nation,the fundamental plan of“successor,”and the construction of modern Chinese spiritual civilization.In the era of big data,the moral education of youth is facing new challenges and opportunities.The wide application of big data technology has brought about an information explosion,exposing young people to more diverse and complex social information.It not only brings opportunities for positive moral education but also many challenges.The main problems of youth moral education in the era of big data are neglected youth subjectivity,insufficient youth moral practice,and utilitarian youth value orientation.We should develop personalized moral education programs,strengthen the integration of moral knowledge and action,and pay more attention to moral practice to improve the pertinence and effectiveness of moral education for young people in the era of big data.

The moderating effect of physical activity on the relationship between bullying and mental health among sexual and gender minority youth

Background:Sexual and gender minority youth frequently experience bullying,which often contributes to higher depressive symptoms and lower self-esteem.Given that physical activity(PA)can mitigate depressive symptoms and improve self-esteem,we examined the moderating effect of PA on the relationship between bullying and mental health among sexual and gender minority youth.Methods:Data from the Lesbian,Gay,Bisexual,Transgender,and Queer National Teen Survey(n=9890)were analyzed.Hierarchical regression analyses examined the influence of history and frequency of being bullied,PA,and the interaction of these variables on depressive symptoms and self-esteem.Simple slopes analyses were used to probe significant interactions.Results:Results indicated the importance of accounting for bullying history when examining effects of PA on mental health.PA was negatively related to depression(t=-4.18,p<0.001)and positively related to self-esteem(t=12.11,p<0.001).Bullying frequency was positively related to depression(t=19.35,p<0.001)and negatively related to self-esteem(t=-12.46,p<0.001).There was a significant interaction between bullying frequency and PA for depression(t=4.45,p<0.001)and self-esteem(t=-4.69,p<0.001).Post hoc analyses suggested that the positive effects of PA on mental health may be limited to those not bullied because it had a negligible effect on those who were bullied.Conclusion:Results suggest that sexual and gender minority youth exercise interventions aiming to improve mental health should first address bullying history;otherwise,their effectiveness may be limited to those who have been bullied.

Physical fitness before and during the COVID-19 pandemic:Results of annual national physical fitness surveillance among 16,647,699 Japanese children and adolescents between 2013 and 2021

Background:Limited nationally representative evidence is available on temporal trends in physical fitness(PF)for children and adolescents during the coronavirus disease 2019(COVID-19)pandemic.The primary aim was to examine the temporal trends in PF for Japanese children and adolescents before and during the COVID-19 pandemic.The secondary aim was to estimate the concurrent trends in body size(measured as body mass and height)and movement behaviors(exercise,screen,and sleep time).Methods:Census PF data for children in Grade 5(aged 10-11 years)and adolescents in Grade 8(aged 13-14 years)were obtained for the years 2013-2021 from the National Survey of Physical Fitness,Athletic Performance,and Exercise Habits in Japan(n=16,647,699).PF and body size were objectively measured,and movement behaviors were self-reported.Using sample-weighted linear regression,temporal trends in mean PF were calculated before the pandemic(2013-2019)and during the pandemic(2019-2021)with adjustments for age,sex,body size,and exercise time.Results:When adjusted for age,sex,body size,and exercise time,there were significant declines in PF during the pandemic,with the largest declines observed in 20-m shuttle run(standardized(Cohen’s)effect size(ES)=-0.109 per annum(p.a.))and sit-ups performance(ES=-0.133p.a.).The magnitude of the declines in 20-m shuttle run and sit-ups performances were 18-and 15-fold larger,respectively,than the improvements seen before the pandemic(2013-2019),after adjusting for age,sex,body size,and exercise time.During the pandemic,both body mass and screen time significantly increased,and exercise time decreased.Conclusion:Declines in 20-m shuttle run and sit-ups performances suggest corresponding declines in population health during the COVID-19pandemic.

Lacrosse-related injuries in boys and girls treated in U.S.emergency departments,2000-2016

Background:Lacrosse is one of the fastest-growing sports in the United States.Its rules regarding permitted contact differ by sex and age.There are no known studies using a nationally representative data set to analyze lacrosse injury patterns over several years by sex and age in the youth population.Methods:A retrospective analysis was performed using data from the National Electronic Injury Surveillance System for youth aged 11-18 years who were treated for lacrosse-related injuries in U.S.emergency departments from 2000 to 2016.Based on our review of the case narratives,we created and coded a new injury-mechanism variable.We generated national estimates from 6406 cases.Results:An estimated 206,274 lacrosse-related injuries to youths aged 11-18 years were treated in U.S.emergency departments from 2000 to 2016.The rate of injuries per 10,000 significantly increased from 1.9 in 2000 to a peak of 5.3 in 2012(p<0.0001),followed by a significant decrease to 3.4 in 2016(p=0.020).Injury mechanism,body part injured,and diagnosis differed by sex.Boys were 1.62 times(95%confidence interval(95%CI):1.25-2.09)more likely than girls to be injured by player-to-player contact.Girls were 2.21 times(95%CI:1.96-2.49)more likely than boys to have non-contact injuries.Overall,as age increased,the percentage of injuries from lacrosse sticks decreased and player-toplayer contact increased.Conclusion:Despite additional protective regulations in the sport,lacrosse is an important source of injury where we continue to see differences by sex and age.This study supports the continuation,modification,and addition of rules aimed at reducing lacrosse injury risk.
