**Abstract:** Three key health behaviors, physical activity (PA), sedentary behavior (SB) and sleep (SLP), have been identified by the 24-h framework as movement behaviors. School-based interventions targeting these multiple health behaviors among children have the potential to increase health outcomes. Despite this, the efficacy and sustainability of school-based movement behavior interventions among children has not been evaluated yet. To fill this gap in literature, this systematic review will aim to: (1) Summarize and classify movement behavior strategies used in literature to improve PA, SB and SLP in/from school in children; and (2) measure the effect of movement behavior strategies used in literature to improve PA, SB and SLP in children. The review protocol was registered in PROSPERO (CRD42020199154). A systematic search will be conducted between 2010 to 2020 in five databases: Pubmed, Scopus, SPORTDiscuss, The Cochrane Library and Web of Science. Risk of bias and quality assessment will be evaluated and measured according to the recommended tools. This systematic review will provide information about which kind of school-based movement behavior interventions are effective, sustainable and the best to implement in children.

**Keywords:** 24-h guidelines; movement behaviors; physical activity; sedentary behavior; sleep; school; children; intervention program

## 1. Introduction

Public health concern has increased over the past decade due to the rise of non-communicable diseases as the first cause of death worldwide [1]. It is known that insufficient physical activity (PA) is one of the most important health behavioral risks for non-communicable diseases in children, youths, and especially in adults [1–3]. Sedentary behaviors (SB) such as sedentary screen-time behaviors (i.e., TV viewing, computer use, playing video-games, or smartphone use), and sitting time (i.e., leisure and occupational sedentary time) are behaviors closely related to physical inactivity in children, but must be considered separately [4,5]. Related to sleep (SLP) behavior, some studies have shown that unhealthy SLP (i.e., irregular sleep patterns, poor sleep quality and short sleep duration) is associated with a higher risk of obesity and a lack of health outcomes (e.g., good physical shape, physical and psychological well-being, healthy dietary patterns, and cognitive performance) among children and adolescents worldwide [6–8]. For convenience only the acronyms PA, SB and SLP instead of their full expressions will be used throughout the manuscript.

Some research studies indicated that the adoption of a healthy lifestyle during childhood can have protective effects against the onset of chronic disease [9], and health-related behaviors acquired at this age usually tend to persist into adulthood [10], so it can influence sustainable long term health behaviors. PA, SB and SLP, separately and combined, can influence and increase health benefits in children [11,12]. These three health behaviors are correlated [13–16] and can interact among them to increase healthy outcomes (e.g., high PA/low SB/improve SLP) in children and youths [17]. Traditionally, school health research has been mainly focused on promoting PA and reducing SB in children [11], but SLP research has usually been treated independently and separately [18]. Although this approach has been very important to the field so far, emerging evidence indicates that today another integrated approach is necessary to understand and promote school health behaviors in children [17,19]. PA is an important health behavior, but only accounts for a small part of daily time, however SB and SLP make up the majority of a 24-hour period [20]. As a consequence, a new paradigm was developed in 2016, called the 24-hour Movement Guidelines [17,21]. This framework recognizes and integrates the importance of correctly combining PA, SB and SLP to reach and improve health outcomes in children [12]. According to the recommendations provided by the 24-h Movement Guidelines [17] and the WHO [22], children aged 5–12 years should accumulate >60 min of daily moderate-to-vigorous physical activity (MVPA), spend several hours in a day doing Light Physical Activity (LPA), sleep more than 9 h per night and dedicate less than 2 h each day to sedentary screen-time behaviors.

Previous studies suggested that combinations of behaviors (e.g., increase PA, reduce SB and improve SLP quality) can impact health in a different way that would not be explained by the effect of individual behaviors studied separately [23,24]. Interventions targeting a combination of multiple health behaviors are a promising method to improve several health outcomes [25]. This approach evidences that changing one health behavior could affect or improve others [25,26]. However, interventions that simultaneously address several health behaviors are usually difficult to implement at schools [26], especially due to various barriers and limitations (e.g., lack of teacher's formation in health promotion, a limited school timetable, the school curricula organization, etc.). On the other hand, interventions that combine PA (e.g., MVPA, LPA), SB (e.g., short sitting time, low screen-time) and SLP (e.g., high sleep quality, high sleep duration) have shown more beneficial outcomes compared with interventions that do not combine these behaviors [12,20]. School is an ideal setting for health promotion behaviors in children, because the majority of the population stay there for a long period of their lifetime, and children spend approximately 50% of their daily waking time at school [27]. Today, school children spend approximately 6–8 h per day at school, being sedentary [28,29], so it is even more important to target school interventions that can increase PA (i.e., MVPA and LPA) and reduce SB (i.e., sitting time and screen time). Considering the 24-h movement guidelines framework, SLP should also be considered.

There are multiple reviews targeting PA [30–34], SB [27,35–38] and SLP [18,39–41] interventions separately, but there is a lack of reviews about multiple health behavior (i.e., 3 or more health behaviors) interventions. We have only found some reviews that target combined health behavior interventions (e.g., PA and SB, PA and SLP) in children that address issues such as obesity prevention [42–45], weight gain prevention [46], energy-balance [47], and preschoolers aged 0–4 years [48]. Other reviews related to multiple health behavior interventions (e.g., PA and SB, PA and SLP) have mainly focused on adolescents [26,49–53] and suggested that although they were effective in terms of PA outcomes, more evidence and high quality studies are required to determine their effectiveness related to other health behaviors such as SB or SLP.

Some recent reviews have focused on examining effective PA and SB strategies [45,54] and a recent umbrella review about school-based interventions to prevent weight gain in children has been published [46]. However, to the authors' knowledge, none of the previously published systematic reviews have exclusively dealt with the effectiveness of strategies related to movement behaviors (i.e., PA, SB and SLP) from multiple health behavior interventions in school children. As a consequence, to fill this gap in literature, this systematic review will aim to: (1) Summarize and classify movement behavior
strategies used in literature to improve PA, SB and SLP in/from school in children; and (2) measure the
effect of movement behavior strategies used in literature to improve PA, SB and SLP in children.

## 2. Materials and Methods

The protocol for this systematic review was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines [55], and it is available in Supplementary Material 1. This systematic review protocol was registered in PROSPERO (CRD42020199154), International Prospective Register of Systematic Reviews, and the report of this systematic review will be informed by PRISMA guidance [56]. Relevant modifications to this protocol will be indicated and published in the corresponding final systematic review.

### 2.1. Eligibility Criteria

To be eligible for the current systematic review, studies will be selected based on the following criteria. Studies must be published in a peer-reviewed English language journal, and target healthy school-children aged 5–12 years (i.e., primary school) without mental disabilities. Study participants are required to have a mean age of 5–11.99 years with at least two exposure measurement points, although follow-up measures of movement behaviors could happen past this age limit. The proposed systematic review will include interventional designs (i.e., randomized controlled trials, cluster randomized controlled trials and non-randomized studies [e.g., quasi-experimental studies, pilot studies and single group]) examining the influence of school-based interventions on movement behaviors. To be included in this systematic review, studies will be required to incorporate at least two movement behaviors from the three 24h movement behaviors (i.e., PA and SB and SLP; PA and SB; PA and SLP; SB and SLP). These behaviors could be assessed by self-report (e.g., questionnaires) or device-based measures (e.g., accelerometer data, pedometers, etc.). According to the eligibility criteria of the recent SB review and meta-analysis conducted by Blackburn et al., [57], all outcomes relating to SB (i.e., leisure or occupational sitting time and sedentary screen-time behaviors) will be included. Furthermore, in line with another review protocol [58] and meta-analysis [26], studies addressing other health behaviors (e.g., dietary patterns, healthy nutrition, well-being, etc.), in addition to our movement behaviors of interest, will not be excluded for the review. Thus, in Figure 1, we show the logic model, as recommended in literature [59,60] to map, inform, make more transparent, and ultimately describe the conceptualization of the protocol review. Finally, according to these recommendations [61], grey literature (e.g., book chapters, editorials, pre-prints, abstracts, congress communications, etc.) will not be included in the search strategy because grey literature is typically not published in peer-reviewed scholarly resources (i.e., journals), and could result in a large increase in the number of records to screen, with little added value for those that have already been identified.

### 2.2. Search Strategy

This systematic search will be conducted using the following electronic databases of peer-reviewed journal articles and online research registers: Pubmed, Scopus, SPORTDiscuss, The Cochrane Library and Web of Science, following the recommendations to conduct academic search systems for systematic reviews and meta-analyses [62]. The expected school-based strategies to be found in the intervention studies extracted across these databases search, will belong to specific theoretical frameworks (i.e., Socio-ecological Model, Theory of Planned Behavior, Self-determination Theory, Social Cognitive Theory, Theory of Reasoned Action, Coordinated School Health Model, Intervention Mapping, Preceed-Proceed Model and Behavior Change Methodology) according to what is shown in Figure 1. Searches will be conducted for studies published between 2010 and October 2020, coinciding with the last decade. Eligible papers will be reviewed to identify other relevant potential studies that could be selected. Similarly, recent related systematic reviews will be consulted to identify any additional studies. The Population, Interventions, Comparisons, Outcomes and Study design (PICOS) framework [63] was followed to conduct the literature search (see Table 1). This strategy allows to
identify key study concepts in the research question, like the logic model presented previously in Figure 1, and facilitate the search process [64]. Described search keywords are related to the following topics: target population (i.e., children), intervention (i.e., different strategies, techniques and health programs), and movement behaviors outcomes (i.e., PA, SB and SLP) in/from school. Search keywords will be combined with different Boolean operators (e.g., "AND", "OR", "NOT"). Selected keywords are based on previous systematic reviews that include some movement behaviors [12,47,50,54,65]. More detailed information about search strategy is available in Supplementary material 2.

## 2.3. Study Selection

All identified studies from the literature search will be selected by two review authors in three steps as recommended in literature [61]. First, the titles and abstracts of the articles returned from the initial search will be screened and selected based on previous broken-down eligibility criteria. Second, full-text articles will be analyzed in detail and selected for eligibility. Third, the bibliographic references of all articles considered will be manually searched to identify relevant articles lost in the initial search strategy. If necessary, disagreements between the authors will be resolved by face-to-face discussion with the rest of authors to reach a consensus. Mendeley Citation Manager software will be used to store search results as well as to remove duplicate studies.

## 2.4. Data Extraction

Two review authors will independently and systematically extract data from included studies. The PRISMA guidance [56] will be used as a reference framework. Authors will identify the required information (i.e., publication details [i.e., authors, year], study characteristics [i.e., design, country, sample size, socio-economic status (SES), age and gender], movement behaviors targeted [i.e., PA, SB and SLP], theoretical framework [e.g., socio-ecological model, theory of planned behavior, etc.], intervention characteristics [i.e., delivery method, content and components], intervention frequency and duration [e.g., 3 intervention sessions/week during 14 weeks], stakeholders involved [i.e., teachers, families, community members, etc.], measurement tools [i.e., questionnaires, accelerometer data], main findings [related to outcomes measured] and follow-up if available). Possible future discrepancies between the authors will be solved by a consensus-based decision, or if necessary, a discussion with a third reviewer. If data clarifications are needed, authors of the original studies will be contacted. If necessary, authors from this protocol will make a maximum of two attempts of contact. All the extracted data will be synthesized using tables created with Microsoft Excel.

## 2.5. Risk of Bias and Quality Assessment

Some reviews [61,66] indicated that literature generally failed to correctly identify and differentiate risk of bias from quality assessment. Thus, risk of bias refers to potential systematic errors that produce bias in final results. Quality assessment is the rigor and quality control in the research methodology and findings, which gives confidence in the results [67]. In that sense, two authors will independently assess the risk of bias of the selected studies using the "The Cochrane Risk of Bias Tool 2" (RoB-2) [68] for randomized studies, and "ROBINS-I" [69] for non-randomized studies. These tools cover a range of domains of potential bias, and any discrepancies between the raters will be resolved by a third reviewer. Scores will be summed across the domains evaluated to give a final total score of the risk of bias for each study. According to the aforementioned risk of bias tools [68,69], studies will be classified as "high risk" (i.e., if most items are rated with "some concerns", or at least one item is rated with "high risk"); as "some concerns" (i.e., if at least one item is rated with "some concerns"), and finally, as "low risk" (i.e., if all the items are rated as "low risk"). Related to quality assessment, the "Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group" will be used to evaluate intervention studies without control group, and the "Quality Assessment of Controlled Intervention Studies" will be used [61] to evaluate intervention studies with control group. The "Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group" integrates 12 items (NIH: https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools) having the option to obtain a maximum score of 12 points. The "Quality Assessment Tool of Controlled Intervention Studies" integrates 14 items (NIH: https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools) having the option to obtain a maximum score of 14 points. Each item will be rated as "1" when the information is reported or moderately reported, or "0" when the information is unclear or not reported. Intervention studies with no control group will be classified into "high quality" (>8 points), "medium quality" (4-7 points), and "low quality" (<3 points). Intervention studies with control group
will be classified into “high quality” (>10 points), “medium quality” (5–9 points), and “low quality” (<4 points). Two authors will independently assess each study, and discrepancies will be resolved by a third reviewer. We will not exclude studies based on findings from the quality assessment.

## 2.6. *Data Synthesis*

A narrative synthesis on all available data will be conducted. Depending on the results, authors will decide to conduct a meta-analysis or simply a qualitative synthesis. If only a qualitative synthesis is finally carried out, summary tables describing studies will be performed. Qualitative analysis will answer our first goal referenced in the background: "to summarize and classify movement behavior strategies used in the literature to improve PA, SB and SLP in/from school in children". These tables will include the general details of the studies, the intervention content (i.e., movement behaviors targeted and theoretical framework), the delivery method (i.e., school, family, teacher or children strategies and stakeholders involved), and the socio-ecological level stage (i.e., individual, interpersonal, organizational, community or policy). A second table will include methodological quality of studies (i.e., risk of bias and quality of assessment). If possible, a quantitative analysis (i.e., meta-analysis) of all defined movement behavior effects (i.e., pre-post, follow-up), where enough data is available, will also be conducted. Quantitative analysis will answer our second goal referenced in the background: "to measure the effect of movement behavior strategies used in literature to improve PA, SB and SLP in children". We anticipate a high degree of heterogeneity with respect to intervention types/lengths, reporting of outcomes and outcome measurements.

## 3. Discussion

The proposed systematic review will be the first to evaluate the school-based movement behavior interventions designed to promote healthy outcomes among children and their efficacy: Increase PA (i.e., MVPA, LPA), reduce SB (e.g., sitting and screen-time) and improve SLP (i.e., sleep patterns, duration and quality). This systematic review of recent and older studies will also allow us to obtain information about the degree of development and sustainability of interventions addressing movement behaviors among primary school students. Although there are some recent systematic reviews, which have examined health behavior interventions in children and adolescents, these were focused on preventing diseases or unhealthy behaviors (e.g., overweight, obesity, physical inactivity, alcohol and smoke consumption, etc.), instead of promoting health behaviors [26,45,46,54]. Consequently, there is a lack of reviews focused on targeting movement behavior interventions in children. Thus, this protocol provides a description of the future systematic review to be carried out, exploring this literature gap. According to our task to find multiple health behavior intervention studies, previous reviews [26,45] found that studies usually do not detail their strategies or methods of intervention, and further high quality research is needed. In order to do that, an important number of methodological unclear studies is expected to be found in our future search. In addition, a review and meta-analysis carried by Champion et al., [26] found that school-based multiple health behavior interventions were beneficial in increasing PA, and reducing screen time (i.e., SB), but concluded that effects were small and the overall quality of evidence was low (measured by GRADE [Grading of Recommendations Assessment, Development and Evaluation] framework). As mentioned in the introduction, combinations of health behaviors can impact health in a different way, which would be not explained by the effect of individual behaviors separately [23,24]. However, recent reviews have found that benefits of single health behavior interventions versus multiple health behavior interventions remained unclear [45,70]. Nevertheless, although there is no consensus in this regard, the present review will only include school interventions targeting at least two movement behaviors simultaneously to further study this topic.

Strengths of this review protocol come firstly from the detailed research guide (i.e., eligibility criteria and search strategy exposed) that will help future researchers to conduct other valid and reliable systematic reviews related to movement behavior interventions. Another methodological strength that should be highlighted in the current review is the detailed quality assessment and risk of bias procedure,
according to recent recommendations to conduct systematic reviews [61]. Related to the limitations of this review, language restriction of published English written studies could limit the generalization of future results. Another limitation is that authors could be ignoring other databases [62] and do not identify more studies in the present systematic review.

## 4. Conclusions

The systematic review to be carried out will provide information about existing studies that have implemented school-based intervention programs targeting movement behaviors to increase health outcomes in children. It is expected that data extracted will be able to identify the most effective strategies and measure the intervention program effect according to our aim. Moreover, results of the present study will show a deeper understanding of which are the most effective and sustainable intervention programs to improve movement behaviors (i.e., PA, SB and SLP) in school-aged children. Finally, reviewing a broad range of adequate intervention programs to improve movement behaviors in/from school will provide information to researchers and practitioners of our field about which kind of interventions and strategies are the best to implement, related to each study design and program objectives.
