Mediator Role

Background: The beneficial relationship between physical fitness and cognitive performance is affected and modulated by a wide diversity of factors that seem to be more sensitive during the development stage, particularly during early adolescence. This study aimed to examine the role of physical fitness considering the multivariate association between age, health-related quality of life (HRQOL), school vulnerability index (SVI), body mass index z-score (BMIz), physical activity, and sleep problems with the cognitive performance in boys and girls.Method: Participants were 1,196 adolescents aged 10–14 years (50.7% of boys) from Chile. Three physical fitness components and eight cognitive tasks were measured. BMIz was determined using growth references by age and sex, whereas questionaries were used to assess sleep problems, physical activity, and HRQOL. SVI was established according to the score given by the Chilean Government to educational establishments. We performed a structural equation model (SEM) to test multivariate associations among study' variables by sex.Results: Fitness was positively associated with boys' and girls' cognitive performance (β = 0.23 and β = 0.17; p = 0.001, respectively). Moreover, fitness presented a significant mediator role in the relationships between BMIz, SVI, and physical activity with cognitive performance (indirect effect). Additionally, SVI showed a negative association both direct and indirect effect in all three fitness components and all cognitive tasks, being this relationship stronger in girls than in boys.Conclusion: Our findings suggest that physical fitness and all its components play a crucial mediator role in the associations between several factors associated with adolescents' cognitive performance. Thereby, educational and health strategies should prioritise improving physical fitness through physical activity. They also should address other factors such as school vulnerability, obesity, and the early gender gap in a comprehensive approach boosting cognitive performance among early adolescents.Trial registration: Research Registry (ID: researchregistry5791).

Mediator Role

This study analyzed the relation between scientific research self-efficacy and metacognitive thinking skills of prospective teachers. Hence this study was executed in relational screening method. The findings of our study unveiled that a significant relation existed between Metacognition thinking subskill domains and scientific research self-efficacy. Accordingly thinking, problem solving, decision making and alternative evaluation skills explained approximately 27% of the score variance of scientific research self-efficacy. In this study three models devised on the principle of structural equation model were tested. It was concluded at the end of this study that decision-making skills played a mediator role between thinking skills and conclusion and discussion skills. Further to that it was identified that thinking skills played a mediator role between literature skills and problem-solving skills. Lastly it was identified that thinking skills played a mediator role between problem solving and conclusion and discussion skills. ÖzetBu çalışmada öğretmen adaylarının bilimsel araştırma öz-yeterlikleri ile üst biliş düşünme becerileri arasındaki ilişki araştırılmaktadır. Dolayısıyla araştırma ilişkisel tarama yöntemine göre yürütülmüştür. Araştırma sonucunda Üst biliş düşünme alt beceri alanlarıyla bilimsel araştırma özyeterliği arasında anlamlı bir ilişki olduğu belirlenmiştir. Buna göre düşünme, problem çözme,  karar verme ve alternatif değerlendirme becerileri bilimsel araştırma özyeterliğine yönelik puanlara ait varyansın yaklaşık %27’sini açıklamaktadır. Araştırmada yapısal eşitlik modeline göre kurulan üç model test edilmiştir. Araştırma sonucunda düşünme becerileri ve sonuç ve tartışma becerileri arasında karar verme becerilerinin aracılık etkisinin olduğu belirlenmiştir. Bunun yanında alanyazın becerileri ve problem çözme becerileri arasında düşünme becerilerinin aracılık etkisinin olduğu gözlenmiştir. Son olarak problem çözme ve sonuç tartışma becerileri arasında düşünme becerilerinin aracılık etkisinin olduğu saptanmıştır.

Background: Stroke is a non-communicable disease that ranks the second leading cause of death in the world. As many as 17 million patients who suffered a stroke, 6.5 million died from a stroke. This disease cannot be cured but can be controlled. The increasing number of cases of non-communicable diseases is related to risk factors. This study aimed to analyze the effect of social capital and factors related to stroke risk. Subjects and Method: A case-control study was conducted at the Ponorogo District Hospital, East Java, from February to March 2020. A sample of 200 patients was taken through fixed disease sampling. The dependent variable was a stroke. The independent variables were social capital, hypertension, residence, workplace, stress, income, dietary habit, education, physical activity. The data was collected using a questionnaire. Data were analyzed using the Structural Equation Model run on Stata 13. Results: The increase in stroke was directly affected by hypertension (b= 2.90; 95% CI= 2.09 to 3.71; p <0.001). The risk of stroke was affected indirectly by social capital, hypertension, workplace, stress, income, dietary habit, education, physical activity. Trust, bonding, bridging, and linking indirectly affected stroke risk on the contribution of social capital measurement. Conclusion: Increased stroke is directly affected by hypertension. Stroke is indirectly affected by social capital, hypertension, workplace, stress, income, dietary habits, education, and physical activity. Trust, bonding, bridging, and linking indirectly affect stroke risk on the contribution of social capital measurement. Keywords:stroke, social capital, risk factors Correspondence: LailatulRohmah.
