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.

Linking 24-h Movement Behavior Guidelines to Cognitive Difficulties,Internalizing and Externalizing Problems in Preterm Youth

Background:Given the heightened risk of developmental challenges associated with preterm birth,it is crucial to explore interventions that may ameliorate potential adverse outcomes.This study aimed to examine whether meeting the 24-h movement behavior(24-HMB)guidelines,which include recommendations on physical activity(PA),screen time(ST),and sleep(SL),is related to indicators of cognitive difficulties,internalizing problems(e.g.,depression and anxiety),and externalizing problems(e.g.,difficulties in making friends and arguing)in a sample of preterm youth(children and adolescents born preterm).Methods:In this cross-sectional study,data from 3410 preterm youth(aged 6 to 17 years)were included for data analyses.Multivariable logistic regression was used to investigate associations between meeting the 24-HMB guidelines and the above-mentioned health outcomes,while controlling for sociodemographic and health-related factors.Results:The prevalence of meeting 24-HMB guidelines varied across independent and integrated components of the 24-HMB guidelines.Meeting the ST guideline alone(p<0.05)and integrated guidelines(i.e.,ST+SL and ST+SL+PA)were associated with fewer cognitive difficulties and reduced internalizing and externalizing problems(p<0.05).Specifically,meeting the SL guideline alone and integrated guidelines(i.e.,SL+ST)were associated with lower odds of depression and anxiety(p<0.01).Additionally,meeting independent,and integrated(PA and/or ST)guidelines were associated with less pronounced difficulties in making friends and arguing(p<0.05).Meeting 24-HMB guidelines in an isolated and integrated manner are linked to better cognitive performance and fewer internalizing and externalizing problems in preterm youth.Conclusion:Results suggest that advocating for the implementation of the 24-HMB guidelines may reduce cognitive challenges and behavioral issues,which is of high relevance for improving public health.Future longitudinal studies in preterm youth should investigate how modifying specific 24-HMB behaviors,especially ST,influence cognitive difficulties,internalizing and externalizing problems in this vulnerable population.

The research improves the accuracy of logging interpretation and provides an effective basis for subsequent production development and potential horizons.

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.

不同初始螺类密度对沉水植物刺苦草Vallisneria spinulosa Yan及其附着藻类的影响

大型水生植物及其附着藻类是浅水湖泊中的重要初级生产者。淡水螺类作为重要的初级消费者,其密度对沉水植物及其附着藻类的影响存在争议。本研究设置4种初始螺类密度(0、40、80、240 ind·m-2),研究淡水螺类(椭圆萝卜螺Radix swinhoei H.Adams)对刺苦草(Vallisneria spinulosa Yan)及其附着藻类的直接牧食作用和螺类种群的变化。结果显示,在添加螺处理中,刺苦草和人工基质表面附着藻类的生物量显著降低,同时沉水植物的生长显著增加,在较高初始密度螺类处理中刺苦草产生更多的分株。到实验结束时,螺类的死亡率较高,但3个有螺处理间螺类鲜重无显著差异,而高初始密度螺类条件下的最终密度仍较高,同时个体重量(均重)也较小。在中富营养条件下淡水螺类可以直接牧食沉水植物叶片,但对植物生长的抑制作用不显著,有可能是因为沉水植物并不能作为唯一的食物来源维持螺类种群,同时螺类的种群结构受到水体营养水平等因素的制约。
