Abstract Background In 2018, the World Health Organisation (WHO) commenced a program of work to update the 2010 Global Recommendations on Physical Activity for Health, for the first-time providing population-based guidelines on sedentary behaviour. This paper briefly summarizes and highlights the scientific evidence behind the new sedentary behaviour guidelines for all adults and discusses its strengths and limitations, including evidence gaps/research needs and potential implications for public health practice. Methods An overview of the scope and methods used to update the evidence is provided, along with quality assessment and grading methods for the eligible new systematic reviews. The literature search update was conducted for WHO by an external team and reviewers used the AMSTAR 2 (Assessment of Multiple Systematic Reviews) tool for critical appraisal of the systematic reviews under consideration for inclusion. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) method was used to rate the certainty (i.e. very low to high) of the evidence. Results The updated systematic review identified 22 new reviews published from 2017 up to August 2019, 14 of which were incorporated into the final evidence profiles. Overall, there was moderate certainty evidence that higher amounts of sedentary behaviour increase the risk for all-cause, cardiovascular disease (CVD) and cancer mortality, as well as incidence of CVD, cancer, and type 2 diabetes. However, evidence was deemed insufficient at present to set quantified (time-based) recommendations for sedentary time. Moderate certainty evidence also showed that associations between sedentary behaviour and all-cause, CVD and cancer mortality vary by level of moderate-to-vigorous physical activity (MVPA), which underpinned additional guidance around MVPA in the context of high sedentary time. Finally, there was insufficient or low-certainty systematic review evidence on the type or domain of sedentary behaviour, or the frequency and/or duration of bouts or breaks in sedentary behaviour, to make specific recommendations for the health outcomes examined. Conclusions The WHO 2020 guidelines are based on the latest evidence on sedentary behaviour and health, along with interactions between sedentary behaviour and MVPA, and support implementing public health programmes and policies aimed at increasing MVPA and limiting sedentary behaviour. Important evidence gaps and research opportunities are identified.

Interest in analyzing physically active behaviors during school recesses has grown in recent years as the school environment has consolidated (recess, physical education classes, lunch-time, before and after school) as a crucial space to bring these levels towards those recommended through intervention programs and improvements in the school environment. Unfortunately, in most of these studies, children do not achieve the 60 min a day of moderate to vigorous physical activity (MVPA) recommended by the World Health Organization. The aim of this systematic review is to analyze the cross-sectional, longitudinal, and intervention studies objectively measured with accelerometers that have emerged in recent years to determine the amount of MVPA of children at recess. This systematic review followed the PRISMA guidelines. The extraction process for the studies included in this systematic review yielded a total of 43 articles. The studies were classified according to the methodological nature of the research: cross-sectional (n = 34), longitudinal (n = 3) and quasi-experimental (n = 6). The results of the studies confirm that during the recess period younger children are physically more active than older ones and that in general, boys are more physically active than girls. In addition, the data show that the school contributes to more than 40% of the total MVPA. The intervention programs led to an increase in MVPA of up to 5%. Providing schools with equipment and facilities shows that intervention programs are beneficial for raising children’s levels of physical activity.

Purpose: To determine how physical activity-related self-efficacy is associated with physical activity and sedentary behaviour time among ambulatory children with cerebral palsy (CP). Method: Children with CP, Gross Motor Function Classification System (GMFCS) Levels I-III ( N = 26; aged 9–18 y), completed the task self-efficacy component of a self-efficacy scale and wore Actigraph GT3X+ accelerometers for 5 days. Correlations (Pearson and Spearman’s rank-order; a = 0.050) were conducted to evaluate the relationships among age, GMFCS level, self-efficacy, and both daily moderate-to-vigorous physical activity (MVPA) and sedentary time. Linear regression models were used to determine the relationships among the independent variables and MVPA and sedentary time. Results: Self-efficacy was positively associated with MVPA time ( r = 0.428, p = 0.015) and negatively correlated with sedentary time ( r = –0.332, p = 0.049). In our linear regression models, gross motor function (β = –0.462, p = 0.006), age (β = –0.344, p = 0.033), and self-efficacy (β = 0.281, p = 0.080) were associated with MVPA time ( R2 = 0.508), while GMFCS level (β = 0.439, p = 0.003) and age (β = 0.605, p < 0.001) were associated with sedentary time ( R2 = 0.584). Conclusions: This research suggests that self-efficacy, age, and gross motor function are associated with MVPA in children with CP. Additional research is needed to confirm these findings and further explore the influence of self-efficacy on sedentary behaviour.

BACKGROUND The World Health Organisation (WHO) defines mHealth as medical and public health practice supported by mobile devices. A number of mHealth devices, primarily apps designed to support contact tracing, have been utilised as part of the public health response to the Covid-19 pandemic. The value of mHealth devices in augmenting public health practice is however yet to be defined. OBJECTIVE The study aims to address three research questions: (1) What digital technologies are being used to track the symptoms and spread of infectious disease outbreaks and what strategies do they use to do so? (2) How effective and cost-effective are digital technologies at tracking the spread of infectious disease outbreaks and what are their strengths and limitations? (3) What are the user perspectives on the usability and effectiveness of these technologies? METHODS The PICOS template and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) will be followed for this systematic review. The review will be composed of a literature search, article selection, data extraction, quality appraisal, data analysis, and a discussion of the implications of the data for the current COVID-19 pandemic. RESULTS N/A CONCLUSIONS This systematic review will summarise the available evidence for use of mHealth devices for tracking the spread of infectious disease outbreaks. These results are potentially valuable for informing public health policy during infectious disease outbreaks such as the current Covid-19 pandemic.

Physical inactivity and sedentary behaviour have been independently associated with a wide range of negative health indicators including obesity, poor cardio-metabolic health, and poor psychosocial health. The overarching objective of this research was to gain a better understanding as to why children are sedentary and where we need to focus public health messages and interventions to reduce sedentary behaviour. Specifically, I aimed to provide insight on current awareness of sedentary behaviour guidelines, determine important correlates of total sedentary time (SED) and screen time (ST) in Canadian children, and understand correlates of SED and ST in a global context. The primary dataset used for this project was the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE). Background work was completed to review current literature on knowledge and awareness of Canadian physical activity and sedentary behaviour guidelines (in all age groups) and to understand the representativeness of the ISCOLE dataset. In addition to the 2 background papers, this dissertation includes 3 manuscripts, all prepared for submission in scientific, peer-reviewed journals: Canadian physical activity and screen time guidelines: do children know?, Correlates of objectively measured sedentary time and self-reported screen time in Canadian children, and Correlates of total sedentary time and screen time in 9–11 year-old children around the world: The International Study of Childhood Obesity, Lifestyle and the Environment. Overall, this work showed the majority of children around the world are accumulating large amounts of sedentary time, and exceeded current screen time guidelines. We found that the large majority of Canadian children are not aware of screen time guidelines; however, a greater proportion of children could identify physical activity guidelines. We also identified a number of correlates of SED and ST in Canadian children and in children around the world. The most common correlates included weight status and access to electronics in the house. Taken together, this work suggests that public health messaging should focus on increasing awareness of screen time guidelines. While increasing awareness of the guidelines, messaging can be tailored to promoting healthy weight status and reducing (or removing) children’s access to electronic devices in hopes of reducing overall time spent sedentary.

Physical Activity Interventions

IntroductionIn Latin America, the number of children and adolescents who are overweight or obese has significantly increased in recent decades, and this situation has become a major public health concern. To address this problem, several intervention programmes, based on factors such as physical activity and nutrition, have been implemented, and body mass index (BMI) has been widely used as a means of measuring the impact of such interventions. Although some Latin America-based systematic reviews have been performed, there have been no previous meta-analyses of findings regarding the effect of physical activity interventions on BMI. Thus, the objective of the systematic review and meta-analysis will be to provide an up-to-date synthesis of the effects of physical activity interventions on BMI of Latin American children and adolescents aged 4–18 years.Methods and analysisThis systematic review and meta-analysis protocol is based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement. The literature search will involve MEDLINE, EMBASE, Cochrane Library, Web of Science and Scielo for articles published up to July 2019. This search will include randomised controlled trials (RCTs), non-randomised experimental studies and single-arm pre–post studies. Further, the Cochrane Collaboration’s tool for RCT studies and the Quality Assessment Tool for Quantitative Studies for non-randomised experimental and single-arm pre–post studies will be used to assess the risk of bias among the studies included in the systematic review. For the meta-analysis, the statistical program STATA V.14 will be used, and standardised mean differences are calculated as the primary outcomes. Subgroup analyses will then be performed based on the characteristics of the interventions and populations included in the studies examined.Ethics and disseminationThis systematic review protocol is designed to provide updated evidence regarding the effects of physical activity interventions on the Latin American population; such evidence may be useful for institutions responsible for the development of public health policies and for those tasked with implementing such interventions among children and adolescents in Latin America. The results should be disseminated through publication in a peer-reviewed journal. Since the data used in systematic reviews of this type will be extracted exclusively from published studies, approval from an ethics committee will not be required.PROSPERO registration numberCRD42019077702.

The Impact

Prolonged lockdown/restriction measures due to the COVID-19 pandemic have reportedly impacted opportunities to be physically active for a large proportion of the population in affected countries globally. The exact changes to physical activity and sedentary behaviours due to these measures have not been fully studied. Accordingly, the objective of this PROSPERO-registered systematic review is to evaluate the available evidence on physical activity and sedentary behaviours in the general population during COVID-19-related lockdown/restriction measures, compared to prior to restrictions being in place. Defined searches to identify eligible studies published in English, from November 2019 up to the date of submission, will be conducted using the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, SPORTDiscus, PSYCinfo, Coronavirus Research Database, Public Health Database, Publicly Available Content Database, SCOPUS, and Google Scholar. The applied inclusion criteria were selected to identify observational studies with no restrictions placed on participants, with outcomes regarding physical activity and/or sedentary behaviour during lockdown/restriction measures, and with comparisons for these outcomes to a time when no such measures were in place. Where appropriate, results from included studies will be pooled and effect estimates will be presented in random effects meta-analyses. To the best of our knowledge, this will be the first systematic review to evaluate one complete year of published data on the impact of COVID-19-related lockdown/restriction measures on physical activity and sedentary behaviour. Thus, this systematic review and meta-analysis will constitute the most up-to-date synthesis of published evidence on any such documented changes, and so will comprehensively inform clinical practitioners, public health agencies, researchers, policymakers and the general public regarding the effects of lockdown/restriction measures on both physical activity and sedentary behaviour.

The Impact

Background The COVID-19 pandemic has entailed a significant socio-economic impact on various layers of the population. In many countries, attempts to control viral dissemination involved lockdown measures that limited citizens' overall mobility and professional and leisure activities. Objective This systematic review investigates the impact of COVID-19-induced lockdowns on university student physical activity and sedentary behav-ior, as these relate to physical and mental well-being. Methods Data was collected through PubMed/MEDLINE, Embase, SCOPUS, and APA PsycInfo databases until January 2021. Results Seven studies conducted in five different countries (United States, Spain, Italy, China, and United Kingdom) were included in the final review. Overall, most studies reported a significant decrease in mild physical activity (i.e., walking) among undergraduate students but not among graduate students. Consistently, most studies reported a significant increase in sedentary time (i.e., sitting time on weekdays) in undergraduate students but not in graduate students. We observed that students who were more sedentary previous to lockdown, increased or did not change their moderate and/or vigorous physical activity. In contrast, those who were less sedentary previous to lockdown decreased their moderate and/or vigorous physical activity. Conclusions COVID 19 induced lockdowns appear to have negatively affected walking and sedentary behavior among undergraduate students but not among graduate students. Our results highlight the importance of promoting the World Health Organization recommendations for physical activity and sedentary behavior among university students to improve health outcomes.
