Physical Activity and School Engagement in Youth: A Systematic Review and Meta-Analysis

Abstract: Physical activity is associated with numerous health benefits in youth; however, these benefits could extend further than health, into education. Our aim was to systematically review and combine in meta-analyses evidence concerning the association between physical activity and the dimensions of school engagement, including behavior (e.g., time-on-task), emotions (e.g., lesson enjoyment), and cognition (e.g., self-regulated learning). We conducted meta-analyses using structural equation modeling on results from 38 studies. Overall, physical activity had a small, positive association with school engagement (d = .28, I2 = .86), 95% confidence interval [.12, .46]. This association was moderated by study design, with significant associations shown in randomized controlled trials but not in studies employing other designs. Risk of bias was also a significant effect moderator, as studies with a low risk of bias showed significant associations but not high risk of bias studies. Altogether, these results suggest t...

Interrupting prolonged sitting with brief bouts of light walking or simple resistance activities reduces resting blood pressure and plasma noradrenaline in type 2 diabetes

Abstract: Objective: Prolonged sitting is increasingly recognized as a ubiquitous cardiometabolic risk factor, possibly distinct from lack of physical exercise. We examined whether interrupting prolonged sitting with brief bouts of lightintensity activity reduced blood pressure (BP) and plasma noradrenaline in type 2 diabetes (T2D). Methods: In a randomized crossover trial, 24 inactive overweight/obese adults with T2D (14 men; mean±SD; 62±6 years) consumed standardized meals during 3-8h conditions: uninterrupted sitting (SIT); sittingRhalf-hourly bouts of walking (3.2 km/h for 3-min) (light-intensity walking); and sittingRhalf-hourly bouts of simple resistance activities for 3 min (SRAs), each separated by 6- 14 days washout. Resting seated BP was measured hourly (mean of three recordings, >20-min postactivity). Plasma noradrenaline was measured at 30-min intervals for the first hour after meals and hourly thereafter. Results: Compared with SIT, mean resting SBP and DBP were significantly reduced (P<0.001) for both lightintensity walking (mean±SEM; -14±1/-8±1mmHg) and SRA (-16±1/-10±1mmHg), with a more pronounced effect for SRA (P<0.05 versus light-intensity walking). Similarly, mean plasma noradrenaline was significantly reduced for both light-intensity walking (-0.3±0.1 nmol/l) and SRA (-0.6±0.1 nmol/l) versus SIT, with SRA lower than light-intensity walking (P<0.05). Mean resting heart rate was lowered by light-intensity walking (-3±1 bpm; P<0.05), but not SRA (-1±1bpm). Conclusion: Interrupting prolonged sitting with brief bouts of light-intensity walking or SRA reduces resting BP and plasma noradrenaline in adults with T2D, with SRA being more effective. Given the ubiquity of sedentary behaviors and poor adherence to structured exercise, this approach may have important implications for BP management in patients with T2D.

The extension of Colaizzi’s method of phenomenological enquiry

Abstract: Aim: Originating from unfunded research undertaken in 2007, this paper offers an overview of Colaizzi’s method of phenomenological analysis and proposes an extension to the original seven step approach enhancing rigour and, expanding information sources to enhance in-depth descriptions of phenomena for study. Background: The focus on human experience emanates from the human sciences in which the everyday lived world of humans constitutes the ontological and epistemological focus of enquiry – understanding of human experiences. Since the emergence of phenomenology as a method of enquiry, advances in phenomenological thought and research methods have emerged. Method: Colaizzi’s phenomenological method of enquiry was used as the basis of enquiry in this study. Findings: The extension to Colaizzi’s method of analysis emanated from recent research conducted by the authors to allow participants to express their experiences through everyday language. These ‘expressions of life’ included – art, music, poetry, metaphor as symbolic representations – as a vehicle for participants’ to explicate their experiences. Conclusion: The additional step proposed as an extension to Colaizzi’s seven step analysis offers researchers using Colaizzi’s method greater access to implicit and explicit meanings embedded in participant descriptions by utilising ‘expressions of life’ – art, music, poetry, metaphor as symbolic representations – as articulated by the participants in explicating their experience of the phenomenon.

Parental ethnic-racial socialization practices and children of color's psychosocial and behavioral adjustment: A systematic review and meta-analysis.

Abstract: Despite increasing empirical research documenting the association between parental ethnic-racial socialization and youth of color's psychosocial well-being, evidence on the extent to which ethnic-racial socialization practices are linked to youth outcomes and potential variation in these relations remains equivocal. In the current study, a meta-analysis of 102 studies with 803 effect sizes and 27,221 participants reveals that overall ethnic-racial socialization was positively, albeit modestly, associated with self-perceptions, interpersonal relationship quality, and internalizing behavior. Ethnic-racial socialization's overall association with externalizing behavior was nonsignificant. Moreover, ethnic-racial socialization's connection to psychosocial outcomes varied by the subtype that parents used, the developmental stage and race/ethnicity of the target child, and the reporter of ethnic-racial socialization. In particular, cultural socialization was positively associated with self-perceptions and interpersonal relationship quality and negatively associated with externalizing behaviors. In addition, ethnic-racial socialization's positive association with self-perceptions was strongest in early adolescence and among African American youth. These findings underscore the complexity of parental ethnic-racial socialization practices and the need for a nuanced perspective on it. Implications for parenting practices and future research are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
