RESUMO
OBJECTIVE: Physical activity (PA) interventions are part of many interdisciplinary programs for the management of children and adolescents with or without physical or psychological conditions or disabilities. Aiming to summarize the available evidence, we conducted an umbrella review of meta-analyses of PA interventions that included psychosocial outcomes in populations of children and adolescents. METHOD: Literature searches were conducted in PubMed, Cochrane Central, Web of Science, Medline, SPORTDiscus, and PsychInfo from January 1, 2010, to May 6, 2022. Meta-analyses of randomized and quasi-randomized studies investigating the efficacy of PA interventions for psychosocial outcomes in children and adolescents were included. Summary effects were recalculated using common metric and random-effects models. We assessed between-study heterogeneity, predictive intervals, publication bias, small study effects, and whether the results of the observed positive studies were greater than expected due to chance. On the basis of these calculations, strength of associations was assessed using quantitative umbrella review criteria, and credibility of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Quality was assessed using the AMSTAR 2 tool. This study is registered with the Open Science Framework, https://osf.io/ap8qu. RESULTS: A total of 112 studies from 18 meta-analyses generating 12 new meta-analyses comprising 21,232 children and adolescents in population groups including attention-deficit/hyperactivity disorder, cancer, cerebral palsy, chronic respiratory diseases, depression, neuromotor impairment, and obesity and in general populations were included. PA interventions were efficacious in reducing psychological symptoms in all meta-analyses across the different population groups using random-effects models. However, umbrella review criteria suggested a weak strength of association for this outcome, and GRADE credibility of evidence ranged from moderate to very low. For psychological well-being, 3 out of 5 meta-analyses identified significant effects, but the strength of these associations was weak, and GRADE credibility of evidence ranged from moderate to very low. Similarly, for social outcomes, meta-analyses reported a significant summary effect, but the strength of association was weak, and GRADE credibility of evidence ranged from moderate to very low. For self-esteem, one meta-analysis in children with obesity failed to show any effect. CONCLUSION: Even though existing meta-analyses suggested a beneficial effect of PA interventions on psychosocial outcomes across different population groups, the strength of associations was weak, and the credibility of evidence was variable depending on the target population, outcome, and condition or disability. Randomized studies of PA interventions in children and adolescents with and without different physical and psychological conditions or disabilities should always include psychosocial outcomes as an important dimension of social and mental health.

BACKGROUND: Implementation science seeks to systematically identify determinants, strategies, and outcomes within a causal pathway to help explain successful implementation. This process is applied to evidence-based interventions (EBIs) to improve their adoption, implementation, and sustainment. However, this method has not been applied to exercise oncology services, meaning we lack knowledge about implementing exercise EBIs in routine practice. This study aimed to develop causal pathways from the determinants, strategies (including mechanism of change), and implementation outcomes to explain exercise EBIs implementation in routine cancer care. METHODS: A multiple-case study was conducted across three healthcare sites in Australia. Sites selected had implemented exercise within routine care for people diagnosed with cancer and sustained the delivery of services for at least 12 months. Four data sources informed the study: semi-structured interviews with staff, document reviews, observations, and the Program Sustainability Assessment Tool (survey). Framework analysis was applied to understand the findings. The Implementation Research Logic Model was used to identify commonalities in implementation across sites and develop causal pathways. RESULTS: Two hundred and eighteen data points informed our findings. Across sites, 18 determinants and 22 implementation strategies were consistent. Sixteen determinants and 24 implementation strategies differed across sites and results of implementation outcomes varied. We identified 11 common pathways that when combined, help explain implementation processes. The mechanisms of implementation strategies operating within the pathways included (1) knowledge, (2) skills, (3) secure resources, (4) optimism, and (5) simplified decision-making processes associated with exercise; (6) relationships (social and professional) and support for the workforce; (7) reinforcing positive outcomes; (8) capability to action plan through evaluations and (9) interactive learning; (10) aligned goals between the organisation and the EBI; and (11) consumer-responsiveness. CONCLUSION: This study developed causal pathways that explain the how and why of successful implementation of exercise EBIs in cancer care. These findings can support future planning and optimisation activities by creating more opportunities for people with cancer to access evidence-based exercise oncology services. IMPLICATIONS FOR CANCER SURVIVORS: Understanding how to implement exercise within routine cancer care successfully is important so cancer survivors can experience the benefits of exercise.

AIM: To describe clinical characteristics of pulmonary hypertension (PH) associated with moderate to severe BPD (MSBPD) in premature infants born ≤32 weeks gestation. METHODS: This was a single centre retrospective cohort study, with reanalysis of echocardiographic studies for PH of infants born ≤32 weeks gestation with MSBPD admitted to a tertiary surgical neonatal service. RESULTS: In total, 268 babies with MSBPD were included in the study. Incidence of BPD-associated PH (BPD-PH) was 12.6% (34), of which 41% infants were observed to have severe PH. On multivariate analysis, need for positive pressure respiratory support at 36 weeks post menstrual age (PMA) was independently associated with PH (p = 0.001; 95% CI 2-13.5) Presence of PH and severity of PH were associated with increased mortality. Of babies with MSBPD-PH, 32% died before discharge from the neonatal unit. CONCLUSION: Babies with MSBPD and PH are more likely to die before discharge from the neonatal unit. Need for positive pressure respiratory support at 36 weeks PMA is independently associated with PH. Babies with MSBPD with less than severe PH are also associated with increased mortality when compared to babies with MSBPD with no PH.

Objectives: Fibrinogen depletion may occur at higher levels than historically referenced. We evaluated hypofibrinogenemia and associated mortality and multiple organ failure (MOF) after severe injury. Methods: Retrospective investigation including 417 adult patients with Injury Severity Score (ISS) >15. Demographics and injury characteristics were collected. Fibrinogen within 30 minutes of admission was described: <150 mg/dL, 150 mg/dL to 200 mg/dL and >200 mg/dL. Primary outcome: 28-day mortality. Secondary outcomes: 28-day MOF and blood product transfusion. Multivariable logistic regression model evaluated association of fibrinogen categories on risk of death, after controlling for confounding variables. Results presented as OR and 95% CIs. Results: Fibrinogen <150 mg/dL: 4.8%, 150 mg/dL to 200 mg/dL: 18.2%, >200 mg/dL: 77.0%. 28-day mortality: 15.6%. Patients with <150 mg/dL fibrinogen had over fourfold increased 28-day mortality risk (OR: 4.9, 95% CI 1.53 to 15.7) after adjusting for age, ISS and admission Glasgow Coma Scale. Patients with lower fibrinogen were more likely to develop MOF (p=0.04) and receive larger red blood cell transfusion volumes at 3 hours and 24 hours (p<0.01). Conclusions: Fibrinogen <150 mg/dL is significantly associated with increased 28-day mortality. Patients with fibrinogen <150 mg/dL were more likely to develop MOF and required increased administration of blood products. The optimal threshold for critically low fibrinogen, the association with MOF and subsequent fibrinogen replacement requires further investigation. Level of evidence: Level III.
RESUMO
BACKGROUND: Implementation science frameworks explore, interpret, and evaluate different components of the implementation process. By using a program logic approach, implementation frameworks with different purposes can be combined to detail complex interactions. The Implementation Research Logic Model (IRLM) facilitates the development of causal pathways and mechanisms that enable implementation. Critical elements of the IRLM vary across different study designs, and its applicability to synthesizing findings across settings is also under-explored. The dual purpose of this study is to develop an IRLM from an implementation research study that used case study methodology and to demonstrate the utility of the IRLM to synthesize findings across case sites. METHOD: The method used in the exemplar project and the alignment of the IRLM to case study methodology are described. Cases were purposely selected using replication logic and represent organizations that have embedded exercise in routine care for people with cancer or mental illness. Four data sources were selected: semi-structured interviews with purposely selected staff, organizational document review, observations, and a survey using the Program Sustainability Assessment Tool (PSAT). Framework analysis was used, and an IRLM was produced at each case site. Similar elements within the individual IRLM were identified, extracted, and re-produced to synthesize findings across sites and represent the generalized, cross-case findings. RESULTS: The IRLM was embedded within multiple stages of the study, including data collection, analysis, and reporting transparency. Between 33-44 determinants and 36-44 implementation strategies were identified at sites that informed individual IRLMs. An example of generalized findings describing "intervention adaptability" demonstrated similarities in determinant detail and mechanisms of implementation strategies across sites. However, different strategies were applied to address similar determinants. Dependent and bi-directional relationships operated along the causal pathway that influenced implementation outcomes. CONCLUSIONS: Case study methods help address implementation research priorities, including developing causal pathways and mechanisms. Embedding the IRLM within the case study approach provided structure and added to the transparency and replicability of the study. Identifying the similar elements across sites helped synthesize findings and give a general explanation of the implementation process. Detailing the methods provides an example for replication that can build generalizable knowledge in implementation research.
RESUMO
Diameter of the patent ductus arteriosus (PDA) on transthoracic echocardiography (TTE) is used as a marker of haemodynamic significance. We aimed to assess the intra- and inter-observer variability in PDA diameter in babies born at ≤ 30 weeks' gestation. TTEs for 56 infants were performed by a single neonatologist. Cineloops were stored without measurement annotations. PDAs were measured on 2-dimensional (2D) and Colour Doppler. A second, blinded neonatologist repeated measurements on the same cineloops. The scanning neonatologist repeated measurements at a later date, blinded to original measurements. Inter-observer results showed repeatability coefficients of 1.57 (2D) and 2.18 (Colour), and repeatability index of 73% (2D) and 91% (Colour). Intra-observer results showed repeatability coefficients of 0.99 (2D) and 1.32 (Colour), and repeatability index of 43% (2D) and 49% (Colour).Conclusion: There is significant inter- and intra-observer variability in measurements of PDA diameter, even on the same cineloops. We advise caution when using diameter alone as a marker of haemodynamic significance, and recommend using multiple parameters to determine haemodynamic significance of PDA. What is Known: ⢠PDA is associated with numerous comorbidities such as bronchopulmonary dysplasia, necrotising enterocolitis, intraventricular haemorrhage and mortality. ⢠PDA diameter is commonly measured on transthoracic echocardiography and used as a marker of haemodynamic significance. ⢠A previous, smaller study has shown there may be poor repeatability of PDA diameter measurements in serial echocardiograms. What is New: ⢠There is significant inter-observer variability in 2D and Colour Doppler measurements of PDA internal diameter on TTE in preterm infants. ⢠There is moderate intra-observer correlation of repeated measurements on the same imaging in both 2D and Colour Doppler imaging.

Effective physical activity messaging plays an important role in the pathway towards changing physical activity behaviour at a population level. The Physical Activity Messaging Framework (PAMF) and Checklist (PAMC) are outputs from a recent modified Delphi study. This sought consensus from an international expert panel on how to aid the creation and evaluation of physical activity messages. In this paper, we (1) present an overview of the various concepts within the PAMF and PAMC, (2) discuss in detail how the PAMF and PAMC can be used to create physical activity messages, plan evaluation of messages, and aid understanding and categorisation of existing messages, and (3) highlight areas for future development and research. If adopted, we propose that the PAMF and PAMC could improve physical activity messaging practice by encouraging evidence-based and target population-focused messages with clearly stated aims and consideration of potential working pathways. They could also enhance the physical activity messaging research base by harmonising key messaging terminologies, improving quality of reporting, and aiding collation and synthesis of the evidence.

INTRODUCTION: Physical activity messaging is an important step in the pathway towards improving population physical activity levels, but best practice is not yet understood. A gap in the literature exists for a physical activity messaging framework to help guide creation and evaluation of messages. This study aimed to further develop and improve, and gain international expert consensus on, a standardised Physical Activity Messaging Framework and Checklist. METHODS: A modified Delphi study consisting of three online survey rounds was conducted. Each survey gathered feedback from an international expert panel using quantitative and qualitative methods. The framework and checklist were amended between each round based on survey results until consensus (defined a priori as 80% agreement) was reached. RESULTS: The final expert panel (n = 40, 55% female) came from nine countries and comprised academics (55%), healthcare and other professionals (22.5%) and government officials or policymakers (22.5%). Consensus was reached in survey 3 with 85 and 87.5% agreement on the framework and checklist, respectively. CONCLUSION: This study presents an expert- and evidence-informed framework and checklist for physical activity messaging. If used consistently, the Physical Activity Messaging Framework and Checklist may improve practice by encouraging evidence-based and target audience-focused messages, as well as enhance the research base on physical activity messaging by harmonising key terminologies and improving quality of reporting. Key next steps include further refining the Physical Activity Messaging Framework and Checklist based on their use in real-world settings.

OBJECTIVES: To evaluate the association of admission blood glucose ≥200 mg/dL and surgical site infection in orthopaedic trauma surgery. DESIGN: Retrospective, case control study. SETTING: Academic trauma center. PATIENTS: Four hundred sixty-five nondiabetic, noncritically ill orthopaedic trauma patients with an extremity, pelvic, or acetabular fracture and requiring open reduction and internal fixation or intramedullary nailing. INTERVENTION: None. MAIN OUTCOME MEASUREMENTS: Ninety-day deep surgical site infection. RESULTS: Admission blood glucose ≥200 mg/dL was significantly associated with the primary outcome (8/128, 6.3% vs. 35/337, 1.8%; P = 0.01). Multivariable logistic regression modeling demonstrated that admission blood glucose ≥200 mg/dL was a significant risk factor for deep surgical site infections [odds ratio (OR): 4.7, 95% confidence interval (CI) 1.4-15.7], after controlling for male gender (OR: 1.8, 95% CI: 1.1-3.1), prior drug or alcohol abuse (OR: 1.9, 95% CI 0.9-4.0), open fracture (OR: 6.4, 95% CI 3.7-11.0), and fracture region (upper extremity OR: reference; pelvis/hip OR: 3.9, 95% CI 1.6-9.7; femur OR: 2.0, 95% CI 0.88-4.8; tibia/ankle OR: 3.3, 95% CI 1.7-6.2; and foot OR: 2.7, 95% CI 1.2-6.3). CONCLUSIONS: Admission glucose ≥200 mg/dL was a significant independent risk factor for 90-day deep surgical site infections in orthopaedic trauma patients and may serve as an important marker for infection risk. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: Exercise is efficacious for people living after a cancer diagnosis. However, implementation of exercise interventions in real-world settings is challenging. Implementation outcomes are defined as 'the effects of deliberate and purposive actions to implement new treatments, practices, and services'. Measuring implementation outcomes is a practical way of evaluating implementation success. This systematic review explores the implementation outcomes of exercise interventions evaluated under real-world conditions for cancer care. METHODS: Using PRISMA guidelines, an electronic database search of Medline, PsycInfo, CINAHL, Web of Science, SportsDiscus, Scopus and Cochrane Central Registry of Controlled Trials was conducted for studies published between January 2000 and February 2020. The Moving through Cancer registry was hand searched. The Implementation Outcomes Framework guided data extraction. Inclusion criteria were adult populations with a cancer diagnosis. Efficacy studies were excluded. RESULTS: Thirty-seven articles that described 31 unique programs met the inclusion criteria. Implementation outcomes commonly evaluated were feasibility (unique programs n = 17, 54.8%) and adoption (unique programs n = 14, 45.2%). Interventions were typically delivered in the community (unique programs n = 17, 58.6%), in groups (unique programs n = 14, 48.3%) and supervised by a qualified health professional (unique programs n = 14, 48.3%). Implementation outcomes infrequently evaluated were penetration (unique programs n = 1, 3.2%) and sustainability (unique programs n = 1, 3.2%). CONCLUSIONS: Exercise studies need to measure and evaluate implementation outcomes under real-world conditions. Robust measurement and reporting of implementation outcomes can help to identify what strategies are essential for successful implementation of exercise interventions. IMPLICATIONS FOR CANCER SURVIVORS: Understanding how exercise interventions can be successful implemented is important so that people living after a cancer diagnosis can derive the benefits of exercise.

BACKGROUND: Disease and mortality burdens of unhealthy lifestyle behaviours are often reported. In contrast, the positive narrative around the burdens that an existing behaviour have averted is rarely acknowledged. We aimed to estimate the prevented fraction for the population (PFP) for premature mortality averted by physical activity on a global scale. METHODS: In this descriptive study, we obtained previously published data on physical activity prevalence (2001-16) and relative risks of all-cause mortality for 168 countries. We combined the data in Monte-Carlo simulations to estimate country-specific, mean PFP values, corresponding to percentage of mortality averted, and their 95% CIs. High prevented fractions indicated an increased proportion of deaths averted due to physical activity. Using mortality data for all people in a country aged 40-74 years, we estimated the number of premature deaths averted for all adults and by gender. We present the median and range of the prevented fractions globally, by WHO region, and by World Bank income classification. FINDINGS: The global median PFP was 15·0% (range 6·6-20·5), conservatively equating to 3·9 million (95% CI 2·5-5·6) premature deaths averted annually. The African region had the highest median prevented fraction (16·6% [range 12·1-20·5]) and the Americas had the lowest (13·1% [10·8-16·6]). Low-income countries tended to have higher prevented fractions (group median 17·9% [12·3-20·5]) than high-income countries (14·1% [6·6-17·8]). Globally, the median prevented fraction was higher for men (16·0% [7·8-20·7] than women (14·1% [5·0-20·4]). INTERPRETATION: Existing physical activity prevalence has contributed to averting premature mortality across all countries. PFP has utility as an advocacy tool to promote healthy lifestyle behaviours. By making the case of what has been achieved, the prevented fraction can show the value of current investment and services, which might be conducive to political support.

Adults in Samoa have the third highest obesity prevalence in the world, and the prevalence is higher in women than men. The nutritional status of a household in most low- and middle-income countries is positively influenced by the level of control women have over financial resources. Our analysis examined how consumption of specific dietary groups was associated with different sociodemographic and individual health risk factor groups for women who participated in the 2014 Samoa Demographic and Health Survey. Our research question was explored through multivariate analysis of the 2014 Samoa Demographic and Health Survey dataset. The sociodemographic and health behaviour groups included in our analysis were: urban vs. rural residence, wealth quintile, education level, participation in physical activity program, lives with husband/partner, household size, parity, age, smoking, and alcohol consumption. The following diet variables were included: fruit, vegetables, seafood, high-fat food, sugary drinks, high-salt food, and high-sugar food consumption. There was a high prevalence of unhealthy food consumption and unhealthy dietary patterns among a) a large proportion of the population, and b) across sociodemographic and health behaviour groups, with a higher prevalence of particular at-risk patterns in some specific groups including women of younger age and women of higher wealth. Our analysis highlighted some specific opportunities for policy action, including the need to create an enabling environment for healthier food consumption for Samoan women.

INTRODUCTION: Surgical site infection (SSI) is a key performance indicator to assess the quality of surgical care. Incidence and risk factors for SSI in neonatal surgery are lacking in the literature. AIM: To define the incidence of SSI and possible risk factors in a tertiary neonatal surgery centre. MATERIALS AND METHODS: This is a prospective cohort study of all the neonates who underwent abdominal and thoracic surgery between March 2012 and October 2016. The variables analyzed were gender, gestational age, birth weight, age at surgery, preoperative stay in neonatal intensive care unit, type of surgery, length of stay, and microorganisms isolated from the wounds. Statistical analysis was done with chi-square, Student's t- or Mann-Whitney U-tests. A logistic regression model was used to evaluate determinants of risk for SSI; variables were analyzed both with univariate and multivariate models. For the length of hospital stay, a logistic regression model was performed with independent variables. RESULTS: A total of 244 neonates underwent 319 surgical procedures. The overall incidence of SSIs was 43/319 (13.5%). The only statistical differences between neonates with and without SSI were preoperative stay (<4 days vs. ≥4 days, p < 0.01) and length of hospital stay (<30 days vs. ≥30 days, p < 0.01). A pre-operative stay longer than 4 days was associated with almost three times increased risk of SSI (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.05-8.34, p = 0.0407). Gastrointestinal procedures were associated with more than ten times the risk of SSI compared with other procedures (OR 10.17, 95% CI 3.82-27.10, p < 0.0001). Gastroschisis closure and necrotizing enterocolitis (NEC) laparotomies had the highest incidence SSI (54% and 62%, respectively). The risk of longer length of hospital stay after SSI was more than three times higher (OR = 3.36, 95%CI 1.63-6.94, p = 0.001). CONCLUSION: This is the first article benchmarking the incidence of SSI in neonatal surgery in the United Kingdom. A preoperative stay ≥4 days and gastrointestinal procedures were independent risk factors for SSI. More research is needed to develop strategies to reduce SSI in selected neonatal procedures.

BACKGROUND: Red blood cell (RBC) transfusion can be life-saving; however, the risks of RBC transfusion have been increasingly recognized, and current guidelines recommend restrictive transfusion in most patients. We hypothesized that RBC transfusions are decreasing in surgical patients. STUDY DESIGN AND METHODS: A retrospective review of the National Surgical Quality Improvement Program database was performed from 2011 to 2015. Index cases in five surgical specialties were studied: neurosurgery, thoracic surgery, gynecologic surgery, orthopedic surgery, and vascular surgery. Patient characteristics, preoperative laboratory values, and surgery details were compared between years. The study's primary outcome was perioperative RBC transfusion, which was compared over the 5-year period for each specialty. Secondary outcomes were myocardial infarction and renal failure after surgery. In addition, trends in RBC transfusion between low-risk and high-risk patients and between emergency and elective surgery were examined. RESULTS: RBC transfusion decreased in all surgical specialties except for thoracic and gynecologic surgery. RBC transfusion decreased substantially in orthopedic surgery, falling from 22.4% in 2011 to 6.3% in 2015 (p ≤ 0.0001). High-risk patients had greater reductions in the receipt of RBC transfusion than low-risk patients, and there were no increases in myocardial infarction or renal failure after surgery in any specialty. CONCLUSION: RBC transfusion appears to be decreasing across multiple surgical specialties, with no apparent increase in myocardial infarctions or renal failure. This likely represents an important improvement in patient care. Continued efforts are needed to develop patient blood management programs and further reduce RBC transfusion.

BACKGROUND: There are no nationally representative population-based studies investigating the relationship between physical activity, chronic conditions and multimorbidity (i.e., two or more chronic conditions) in low- and middle-income countries (LMICs), and studies on a multi-national level are lacking. This is an important research gap, given the rapid increase in the prevalence of chronic diseases associated with lifestyle changes in these countries. This cross-sectional study aimed to assess the association between chronic conditions, multimorbidity and low physical activity (PA) among community-dwelling adults in 46 LMICs, and explore the mediators of these relationships. METHODS: World Health Survey data included 228,024 adults aged ≥18 years from 46 LMICs. PA was assessed by the International Physical Activity Questionnaire (IPAQ). Nine chronic physical conditions (chronic back pain, angina, arthritis, asthma, diabetes, hearing problems, tuberculosis, visual impairment and edentulism) were assessed. Multivariable logistic regression and mediation analyses were used to assess the association between chronic conditions or multimorbidity and low PA. RESULTS: Overall, in the multivariable analysis, arthritis (OR = 1.12), asthma (1.19), diabetes (OR = 1.33), edentulism (OR = 1.46), hearing problems (OR = 1.90), tuberculosis (OR = 1.24), visual impairment (OR = 2.29), multimorbidity (OR = 1.31; 95% CI = 1.21-1.42) were significantly associated with low PA. More significant associations were observed in individuals aged ≥50 years. In older adults, depression mediated between 5.1% (visual impairment) to 23.5% (angina) of the association between a chronic condition and low PA. Mobility difficulties explained more than 25% of the association for seven of the eight chronic conditions. Pain was a strong mediator for angina (65.9%) and arthritis (64.9%), while sleep problems mediated up to 43.7% (angina) of the association. CONCLUSIONS: In LMICs, those with chronic conditions and multimorbidity are significantly less physically active (especially older adults). Research on the efficacy and effectiveness of PA in the management of chronic diseases in LMICs is urgently needed. Targeted promotion of physical activity to populations in LMICs experiencing chronic conditions may ameliorate associated depression, mobility difficulties and pain that are themselves important barriers for initiating or adopting an active lifestyle.

Objective: To evaluate the antidepressant effects of exercise in older adults, using randomized controlled trial (RCT) data. Methods: We conducted a meta-analysis of exercise in older adults, addressing limitations of previous works. RCTs of exercise interventions in older people with depression (≥ 60 years) comparing exercise vs. control were eligible. A random-effects meta-analysis calculating the standardized mean difference (SMD) (95% confidence interval [95%CI]), meta-regressions, and trim, fill, and fail-safe number analyses were conducted. Results: Eight RCTs were included, representing 138 participants in exercise arms and 129 controls. Exercise had a large and significant effect on depression (SMD = -0.90 [95%CI -0.29 to -1.51]), with a fail-safe number of 71 studies. Significant effects were found for 1) mixed aerobic and anaerobic interventions, 2) at moderate intensity, 3) that were group-based, 4) that utilized mixed supervised and unsupervised formats, and 5) in people without other clinical comorbidities. Conclusion: Adjusting for publication bias increased the beneficial effects of exercise in three subgroup analysis, suggesting that previous meta-analyses have underestimated the benefits of exercise due to publication bias. We advocate that exercise be considered as a routine component of the management of depression in older adults.
