Parents' Perceptions of Children's and Adolescents' Use of Electronic Devices to Promote Physical Activity: Systematic Review of Qualitative Evidence.

Background: The use of physical activity (PA) electronic devices offers a unique opportunity to engage children and adolescents in PA. For this age group (2-17 years), parents play a key role in promoting healthy lifestyles and regulating the use of electronic devices. Therefore, parents' perceptions of the use of electronic devices for PA in children and adolescents are critical for efficient intervention.

Intelligence quotient-genotype association in dystrophinopathies: A systematic review and meta-analysis.

Aims: Becker muscular dystrophy (BMD) and Duchenne muscular dystrophy (DMD) are associated with intelligence quotients (IQs) lower than the normative values, and it is suggested that IQ is negatively correlated with the number of affected isoforms (i.e., Dp427, Dp140 and Dp71).

Sex differences on the relation among gross motor competence, cognition, and academic achievement in children.

An association between gross motor competence (GMC) and academic achievement (AA) has been described, but the potential mechanisms behind this association are still unknown. It is not known either whether these mechanisms are similar for boys and girls. The aim of this study was to analyse whether the association between GMC and AA is mediated by executive functions (EFs), and to investigate whether this mediation differs by sex.

Mediators between physical activity and academic achievement: A systematic review.

Background: Research has suggested the beneficial effects of physical activity (PA) on academic achievement (AA). However, the mechanisms underlying this influence remain unclear. Some proposed mechanisms include physiological, cognitive, psychological, and behavioral paths.

Fitness and executive function as mediators between physical activity and academic achievement.

Physical activity is related with academic achievement in children. This cross-sectional study aimed to assess whether cardiorespiratory fitness (CRF) and executive function act as mediators of the association between moderate to vigorous physical activity (MVPA) and academic achievement. This study included 186 schoolchildren (9-11 years) from Cuenca, Spain.

Effect of retirement on cognitive function: a systematic review and meta-analysis.

The study aimed to determine the longitudinal association between retirement and cognitive function, including global cognition and memory-related skills. This is a systematic review of longitudinal studies on the association between retirement and cognitive function, using Medline (via PubMed), Scopus, Web of Science and PsycINFO databases from inception to April 2020 and longitudinal studies on the association between retirement and cognitive function. The Newcastle-Ottawa Scale was used to assess risk of bias of included studies.

Prevalence of Risk of Eating Disorders and its Association with Obesity and Fitness.

The university stage is a critical developmental period for young adults, where lifestyles can determine future health. A cross-sectional study including 481 college students was conducted, with the following objectives: 1) to examine the prevalence of risk of developing eating disorders in college students, 2) to assess differences in obesity and physical fitness in those with and without risk of eating disorders, and 3) to determine whether cardiorespiratory fitness, muscular fitness or fat mass were associated with the risk of eating disorders. We measured fat mass percentage (by densitometry), risk of feeding or eating disorders (by SCOFF questionnaire), cardiorespiratory fitness levels and a muscular fitness index.

Executive functions mediate the relationship between cardiorespiratory fitness and academic achievement in Spanish schoolchildren aged 8 to 11 years.

Objectives: Previous research has studied the influence of physical fitness on academic achievement through executive functions. However, the nature of this relationship remains unclear. This study aimed to analyze how cardiorespiratory fitness (CRF) and executive functions are associated with academic achievement and to examine whether the relationship between CRF and academic achievement is mediated by executive functions in schoolchildren.

Arterial Stiffness and Cognition Among Adults: A Systematic Review and Meta-Analysis of Observational and Longitudinal Studies.

Background To estimate the strength of the cross-sectional and longitudinal association between arterial stiffness, measured by pulse-wave velocity, and cognitive function, distinguishing between global cognition, executive functions, and memory and to examine the influence of demographic, clinical, and assessment characteristics on this relationship. Methods and Results Systematic review of MEDLINE (via PubMed), Scopus, and WOS databases from their inception to March 2019, to identify cross-sectional and longitudinal studies on the association between pulse-wave velocity and cognitive domains (ie, global cognition, executive functions, and memory) among adult population. A total of 29 cross-sectional and 9 longitudinal studies support the negative relationship between arterial stiffness and cognitive function, including global cognition, executive function, and memory.
