ObjectiveTo report the prevalence of lower airway dysfunction in athletes and highlight risk factors and susceptible groups.DesignSystematic review and meta-analysis.Data sourcesPubMed, EBSCOhost and Web of Science (1 January 1990 to 31 July 2020).Eligibility criteriaOriginal full-text studies, including male or female athletes/physically active individuals/military personnel (aged 15–65 years) who had a prior asthma diagnosis and/or underwent screening for lower airway dysfunction via self-report (ie, patient recall or questionnaires) or objective testing (ie, direct or indirect bronchial provocation challenge).ResultsIn total, 1284 studies were identified. Of these, 64 studies (n=37 643 athletes) from over 21 countries (81.3% European and North America) were included. The prevalence of lower airway dysfunction was 21.8% (95% CI 18.8% to 25.0%) and has remained stable over the past 30 years. The highest prevalence was observed in elite endurance athletes at 25.1% (95% CI 20.0% to 30.5%) (Q=293, I2=91%), those participating in aquatic (39.9%) (95% CI 23.4% to 57.1%) and winter-based sports (29.5%) (95% CI 22.5% to 36.8%). In studies that employed objective testing, the highest prevalence was observed in studies using direct bronchial provocation (32.8%) (95% CI 19.3% to 47.2%). A high degree of heterogeneity was observed between studies (I2=98%).ConclusionLower airway dysfunction affects approximately one in five athletes, with the highest prevalence observed in those participating in elite endurance, aquatic and winter-based sporting disciplines. Further longitudinal, multicentre studies addressing causality (ie, training status/dose–response relationship) and evaluating preventative strategies to mitigate against the development of lower airway dysfunction remain an important priority for future research.

We report the results of a systematic review and meta-analysis investigating the relationship between perceptual anchoring and dyslexia. Our goal was to assess the direction and degree of effect between perceptual anchoring and reading ability in typical and atypical (dyslexic) readers. We performed a literature search of experiments explicitly assessing perceptual anchoring and reading ability using PsycInfo (Ovid, 1860 to 2020), MEDLINE (Ovid, 1860 to 2019), EMBASE (Ovid, 1883 to 2019), and PubMed for all available years up to June (2020). Our eligibility criteria consisted of English-language articles and, at minimum, one experimental group identified as dyslexic - either by reading assessment at the time, or by previous diagnosis. We assessed for risk of bias using an adapted version of the Newcastle-Ottawa scale. Six studies were included in this review, but only five (n = 280 participants) were included in the meta-analysis (we were unable to access the necessary data for one study).The overall effect was negative, large and statistically significant; g = -0.87, 95% CI [-1.47, 0.27]: a negative effect size indicating less perceptual anchoring in dyslexic versus non-dyslexic groups. Visual assessment of funnel plot and Egger’s test suggest minimal bias but with significant heterogeneity; Q (4) = 9.70, PI (prediction interval) [-2.32, -0.58]. The primary limitation of the current review is the small number of included studies. We discuss methodological limitations, such as limited power, and how future research may redress these concerns. The variability of effect sizes appears consistent with the inherent variability within subtypes of dyslexia. This level of dispersion seems indicative of the how we define cut-off thresholds between typical reading and dyslexia populations, but also the methodological tools we use to investigate individual performance.

ObjectiveTo identify and quantify determinants of anxiety symptoms and disorders experienced by elite athletes.DesignSystematic review and meta-analysis.Data sourcesFive online databases (PubMed, SportDiscus, PsycINFO, Scopus and Cochrane) were searched up to November 2018 to identify eligible citations.Eligibility criteria for selecting studiesArticles were included if they were published in English, were quantitative studies and measured a symptom-level anxiety outcome in competing or retired athletes at the professional (including professional youth), Olympic or collegiate/university levels.Results and summaryWe screened 1163 articles; 61 studies were included in the systematic review and 27 of them were suitable for meta-analysis. Overall risk of bias for included studies was low. Athletes and non-athletes had no differences in anxiety profiles (d=−0.11, p=0.28). Pooled effect sizes, demonstrating moderate effects, were identified for (1) career dissatisfaction (d=0.45; higher anxiety in dissatisfied athletes), (2) gender (d=0.38; higher anxiety in female athletes), (3) age (d=−0.34; higher anxiety for younger athletes) and (4) musculoskeletal injury (d=0.31; higher anxiety for injured athletes). A small pooled effect was found for recent adverse life events (d=0.26)—higher anxiety in athletes who had experienced one or more recent adverse life events.ConclusionDeterminants of anxiety in elite populations broadly reflect those experienced by the general population. Clinicians should be aware of these general and athlete-specific determinants of anxiety among elite athletes.

ObjectiveTo investigate the efficacy of interventions designed to train and develop mental toughness (MT) in sport.DesignSystematic review and meta-analysis.Data sourcesJournal articles, conference papers and doctoral theses indexed in Embase, Scopus, PubMed and SPORTDiscus from inception to 22 November 2019.Eligibility criteria for selecting studiesObservational and pre–post experimental designs on the efficacy of physical and/or psychological interventions designed to promote MT in athletes.ResultsA total of 12 studies, published between 2005 and 2019, were included in the review. A majority of the studies included a sample comprised exclusively of male athletes (54.55%), MT interventions were primarily psychological (83.33%) and most studies measured MT via self-report (75%). The Psychological Performance Inventory (25%), the Mental Toughness Questionnaire-48 (16.67%), and the Mental, Emotional and Bodily Toughness Inventory (16.67%) were the most popular inventories used to measure MT. Methodological quality assessments for controlled intervention studies (k=7), single group pre-test–post-test designs (k=4) and single-subject designs (k=1) indicated that the risk of bias was high in most (75%) of the studies. The meta-analysis involving k=10 studies revealed a large effect (d=0.80, 95% CI 0.30 to 1.28), with variability across studies estimated at 0.56.ConclusionAlthough the findings of this review suggest there are effective, empirically based interventions designed to train MT in sport, practitioners should be aware of the level of validity of intervention research before adopting any of the MT training programmes reported in the applied sport psychology literature.

In 5 of the 12 studies, and among female athletes in 1 study, FMS score ≤14 out of 21 points was associated with subsequent injuries. The overall OR of the selected studies in the meta-analysis was 1.86 (95% CI 1.32 to 2.61) and showed substantial heterogeneity (I2=70%).Summary/ConclusionWhether or not a low FMS score ≤14 out of 21 points is associated with increased risk of injury is unclear. The heterogeneity of the study populations (type of athletes, age and sport exposure) and the definition of injury used in the studies make it difficult to synthesise the evidence and draw definitive conclusions.Trial registration numberCRD42015015579.

Effect Of Age

Abstract This systematic review and meta-analysis quantifies the magnitude and breadth of age-related differences in trust. Thirty-eight independent data sets met criteria for inclusion. Overall, there was a moderate effect of age group on trust (g = 0.22), whereby older adults were more trusting than young adults. Three additional meta-analyses assessed age-related differences in trust in response to varying degrees of trustworthiness. This revealed that older adults were more trusting than young adults in response to neutral (g = 0.31) and negative (g = 0.33), but not positive (g = 0.15), indicators of trustworthiness. The effect of age group on trust in response to positive and neutral cues was moderated by type of trust (financial vs. non-financial) and type of responding (self-report vs. behavioral). Older adults were more trusting than young adults in response to positive and neutral indicators of trustworthiness when trust was expressed non-financially, but not financially. There was also an age-related increase in self-reported, but not behavioral, trust in response to neutral cues. Older adults were more trusting than young adults in response to negative indicators of trustworthiness regardless of the type of trust or type of responding. The reliability of information about trustworthiness (superficial vs. genuine cues) did not moderate any effects of age on trust. Implications of these findings and directions for future research are discussed.

The Impact

Abstract Background: Research suggests that childhood psychological maltreatment (i.e., emotional abuse and emotional neglect) is associated with mental and physical health problems that persist into adulthood, for example anxiety, depression, post-traumatic stress disorder (PTSD), suicidal ideation, and aggression; however, a systematic review and meta-analysis of the existing literature would help clarify the magnitude and moderators of these associations, and the extent to which they may be affected by publication bias, as well as the methodological strengths and weakness of studies in this area.Method: Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline will be employed to structure the review. Several searches will be carried out via databases including Web of Science, Medline, PubMed, PsycINFO, Applied Social Science Index and Abstract, ERIC and EMBASE. Empirical peer reviewed research articles that fit pre-specified eligibility criteria will be included in the review. This review will include literature written in either English or Chinese. Two independent reviewers will screen and assess studies for inclusion in the review as well as extract the data, with consensus reached through discussion in cases of discrepancy. A third reviewer will be consulted to resolve any discrepancies that cannot be resolved through discussion between the original reviewers. The relevant Newcastle-Ottawa scales will be used for assessing the quality of studies. If a sufficient number of comparable studies are retrieved, a meta-analysis will be conducted using a random effects model. Discussion: This systematic review will provide an understanding of the long-term effects of childhood psychological maltreatment on adult mental health, which adds to previous reviews focusing primarily on the effects of physical and sexual abuse. The results of the review will help inform clinical practice in approaches to treating those with a history of psychological maltreatment in childhood. The gaps and weaknesses in the evidence identified will also inform recommendations for future research.

BackgroundPregnancy is an opportunity for health providers to support women to stop smoking.ObjectivesIdentify the pooled prevalence for health providers in providing components of smoking cessation care to women who smoke during pregnancy.DesignA systematic review synthesising original articles that reported on (1) prevalence of health providers’ performing the 5As (‘Ask’, ‘Advise’, ‘Assess’, ‘Assist’, ‘Arrange’), prescribing nicotine replacement therapy (NRT) and (2) factors associated with smoking cessation care.Data sourcesMEDLINE, EMBASE, CINAHL and PsycINFO databases searched using ‘smoking’, ‘pregnancy’ and ‘health provider practices’.Eligibility criteria for selecting studiesStudies included any design except interventions (self-report, audit, observed consultations and women’s reports), in English, with no date restriction, up to June 2017.ParticipantsHealth providers of any profession.Data extraction, appraisal and analysisData were extracted, then appraised with the Hawker tool. Meta-analyses pooled percentages for performing each of the 5As and prescribing NRT, using, for example, ‘often/always’ and ‘always/all’. Meta-regressions were performed of 5As for ‘often/always’.ResultsOf 3933 papers, 54 were included (n=29 225 participants): 33 for meta-analysis. Health providers included general practitioners, obstetricians, midwives and others from 10 countries. Pooled percentages of studies reporting practices ‘often/always’ were: ‘Ask’ (n=9) 91.6% (95% CI 88.2% to 95%); ‘Advise’ (n=7) 90% (95% CI 72.5% to 99.3%), ‘Assess’ (n=3) 79.2% (95% CI 76.5% to 81.8%), ‘Assist (cessation support)’ (n=5) 59.1% (95% CI 56% to 62.2%), ‘Arrange (referral)’ (n=6) 33.3% (95% CI 20.4% to 46.2%) and ‘prescribing NRT’ (n=6) 25.4% (95% CI 12.8% to 38%). Heterogeneity (I2) was 95.9%–99.1%. Meta-regressions for ‘Arrange’ were significant for year (p=0.013) and country (p=0.037).ConclusionsHealth providers ‘Ask’, ‘Advise’ and ‘Assess’ most pregnant women about smoking. ‘Assist’, ‘Arrange’ and ‘prescribing NRT’ are reported at lower rates: strategies to improve these should be considered.PROSPERO registration numberCRD42015029989.

Diagnostic Modalities

Syndesmotic sprains or high ankle sprains are reported to be associated with increasing morbidity and time loss. The aim of this study was to critically appraise literature on epidemiology of syndesmotic sprains through systematic review of published literatures. A systematic review was conducted online for literature published in English using PubMed and Google Scholar, as per PRISMA guidelines up to April 30, 2019. Predefined eligibility criteria were applied, and the data thus compiled were analyzed. A total of 26 studies were found to be eligible, of which three-fourths involved sporting population. Considerable inconsistency in assessment procedure reporting, injury and injury severity definition with variable unit measures used to describe incidence or injury rate was observed. Meta-analysis and intra- and intersports comparison could not be performed owing to the study heterogeneity and methodological variability. There is a need for standardization in future research, specifically with regard to injury assessment and reporting, demanding heightened awareness and improved diagnostic modalities, as injury epidemiology is integral to the overall injury-prevention conundrum.

The Relationship

Adolescent aggression is a global public health with long-lasting and costly emotional, social, and economic consequences, and it is of vital importance to identify those variables that can reduce these behaviors in this population. Therefore, there is a need to establish the protective factors of aggressive behavior in adolescence. While some research has demonstrated the relationship between emotional intelligence (EI) and various aggressive responses in adolescence, indicating that EI—or the ability to perceive, use, understand, and regulate emotions—could be considered a protective factor for the development of aggressive behavior in adolescence, the strength of this effect is not clear. The aim of the present study was to conduct a systematic review of the literature concerning the relationship between aggressive behavior and EI in adolescents and provide a reliable estimate of the relationship between both constructs through a meta-analysis. For this purpose, we searched for relevant articles in English and Spanish in Medline, PsycINFO, and Scopus, obtaining 17 selectable articles based on the search terms used in research in the adolescent population. These studies provide scientific evidence of the relationship between the level of EI assessed from the three theoretical models of EI (performance-based ability model, self-report ability model, and self-report mixed model) and various aggressive responses, showing that adolescents with higher levels of EI show less aggressive behavior. Implications for interventions and guidelines for future research are discussed.

Abstract Background: Concussion is a form of mild traumatic brain injury (mTBI) that disrupts brain function. Although symptoms are mostly transient, recovery can be delayed and result in post-concussive syndrome (PCS). Vestibular and oculomotor deficits are among the most debilitating impairments associated with PCS. Non-pharmacological interventions provide treatment with limited side effects in comparison to pharmacological interventions. The aim of this review is to synthesise and evaluate the effectiveness of non-pharmacological interventions that have been used to target vestibular and oculomotor deficits in PCS.Methods: Advanced searches will be conducted in electronic databases to identify articles eligible for inclusion. Studies employing non-pharmacological treatments for vestibular and/or oculomotor dysfunction in PCS will be included if they meet the eligibility criteria. Outcomes will be those pertaining to measures of oculomotor and vestibular function, in addition to adverse events. Meta-analysis will be undertaken using a random effects model followed by an assessment of clinical significance for each outcome as published in literature. Discussion: While non-pharmacological interventions are used commonly to treat vestibular and oculomotor deficits in PCS, the effectiveness of these treatments is yet to be completely elucidated. The present review will explore the effectiveness of non-pharmacological treatments for vestibular and oculomotor deficits in PCS to inform practice and future research.Systematic review registration: PROSPERO CRD42021254720
