Background
It is widely accepted that physical activity (PA) is beneficial for children’s health [1‐5]. Regular PA lowers risk of chronic diseases such as obesity, coronary heart disease, Type II diabetes, and socio-psychological problems such as anxiety and depression [6‐8]. Despite the known benefits of PA, few Canadian children achieve Canada’s recommended PA guidelines of at least 60 min of moderate-to-vigorous physical activity (MVPA) daily [9]. A focus on active school travel (AST) is appropriate knowing that adequate participation in PA during childhood and adolescence could be critical to the prevention of chronic disease later in life [10].
AST can be defined as any form of human-powered transportation, such as walking, biking, and skateboarding [11]. Children who actively commute to school often attain a higher daily average of MVPA [12, 13]. Furthermore, children who use AST tend to be more physically active and are more likely to meet daily recommendations of MVPA [10, 14, 15] and receive as much as 45 additional minutes of MVPA per day [14]. Despite the known benefits of AST on children’s health, AST behaviour continues to decline [16, 17]. Reversing these trends is possible if researchers can identify the barriers preventing children from walking or biking to school [18]. Previous research suggests that individual’s perceptions of their environments have a stronger and more direct relationship with children’s AST, compared to objectively measured factors [19]. Research investigating children’s independent mobility as a way to promote AST and PA has been suggested [20‐22], which can be accomplished by better understanding the perceptions of barriers encountered on the journey to and from school. In the AST literature perceived barriers are defined as a person’s estimated level of challenges related to intrapersonal, interpersonal, environmental, and policy obstacles to AST [18, 23].

Studies examining children’s perceptions of their environments reveal that they possess meaningful and insightful contributions [24, 25]. Other research has shown that children are extremely cognizant of the links between health, PA, and AST [26‐28]; however, few studies have examined children’s perspectives on AST [28] and fewer studies have assessed the importance and comparison among both child and parent perceptions [29‐32] and the influence these perceptions have on children’s AST [33, 34].
The literature identified distance and safety as the most important barriers to AST. Children are more likely to use AST if their school is nearby and the route is safe [14, 35, 36]. Parents also play an important role in children’s AST decisions, with children whose parents use active transportation are more likely to do so [12, 37]. It has been suggested that future work should also examine the impact varying socioeconomic status (SES) and different types of urbanicity (urban, suburban, rural) have on children’s AST [10], along with a wide range of personal, family, and social factors [38, 39].
A socio-ecological approach that combines individual, interpersonal, and community factors may be the most beneficial form of research in this field [40]. AST is a complex behaviour and using a socio-ecological framework can help to explain how varying levels of features from intrapersonal, interpersonal, environmental, and policy levels influence children’s perceptions of features on their journey to and from school [41, 42]. Currently, there are inconsistencies in methodological approaches within AST research and it remains equivocal to further understand the factors influencing children’s AST [43]. It has also been suggested that future studies should examine parental perceptions and characteristics of the route to school [44]. A growing body of research conducted over the last decade, assesses the relationship between perceived barriers and rates of children’s AST. This research is vital for the development of strategies to improve the overall health and well-being of students, simply by increasing rates of PA.
This study aims to fill gaps in the current literature with the inclusion of both parent and children perceptions of barriers to AST and examining how these perceptions of barriers differ, while accounting for factors at the intrapersonal, interpersonal, and physical environment level. The two objectives of this study, include (1) to evaluate how perceptions of barriers to AST differ between children and their parents, and (2) to analyze how child and parent perceptions of barriers to AST influence how children get to school, while controlling for age, gender, distance between home and school, family composition, and neighbourhood SES.

Methods
This study draws from two projects: Active and Safe Routes to School (ASRTS) and Spatial Temporal Environment and Activity Monitoring (STEAM) project. ASRTS is an ongoing four-year community collaborative research project within 26 schools in Southwestern Ontario, Canada examining AST of elementary school children (activesaferoutes.ca). This program aims to increase student’s AST participation through location specific targeted interventions and schools are selected based on their interest in the program. Presentations are given in every classroom in participating schools and children are sent home with a letter of information and parent survey. Older children in grades 4 to 8 are also given the opportunity to complete a child survey if they receive parental consent and provide their own assent. The final sample includes 3748 children (recruitment rate: 41.7%), with 1660 completed child surveys and 3613 completed parent surveys.
The STEAM project (steamproject.ca) is a study conducted between 2010 and 2013 within 33 schools across Southwestern Ontario examining environmental influences on children’s health and well-being. Further details of this mixed methods project are available elsewhere [45]. Schools were randomly selected from stratified groups based on neighborhood income, with 33 of the 63 schools (52.4%) that were contacted agreeing to participate. Presentations were given in grade 5 to 7 classrooms at participating schools, and letters of information, parent surveys, and parental consent forms were distributed to students. All students with consent were asked to provide assent and complete the child survey. The final sample includes 932 children (recruitment rate 66.9%), with 876 completed child surveys and 758 completed parent surveys.
Data provided by these two studies are collected from parent and child surveys that ask identical questions about AST. The parent survey includes questions about family SES, postal code, the journey to and from school, and perceptions of barriers to AST. The child survey includes questions about child and family demographics and perceptions of barriers to AST. These surveys includes previously-validated questions assessing AST and children’s perceptions of their local environments from other widely-used surveys, including Neighborhood Quality of Life Study and the Neighbourhood Environment Walkability Scale [46‐49].
Sample
The sample used in this study will combine data from the baseline survey of the two projects (N = 4680) from 48 elementary schools across Southwestern Ontario, Canada (i.e., City of London, Middlesex County, City of St. Thomas, Elgin County, Oxford County, Chatham-Kent, City of Sarnia, Lambton County, and Essex County). There are two exclusion criteria for this study. Observations without a parent and child survey completed were removed from the sample, resulting in 2501 children removed from the sample. All children who are bus eligible, defined as living more than 1.6 km from school [44], were excluded from the sample, resulting in 883 more children removed from the sample. Applying the exclusion criteria results in a final sample of 1296 paired parent and child who live within 1.6 km of their school. The characteristics of the final sample can be found in Table 1.
Measures
Dependent variable
There is variation within the literature on consistency of definitions and measurements of AST used in research. A systematic review conducted by Lu and collegues [18] on AST states that although there is currently no “golden rule” for defining AST, it is necessary for researchers to provide a valid rationale for how AST is defined in their research. The dependent variable for this analysis is parent-reported rates of AST from the parent surveys, with students classified as an active traveler if they identified their mode of travel as active more than 50% of their total trips. A 50% cut-off is used for this study, as the results are being used in the development of an intervention that has the goal of getting every child who lives within walking distance to walk on a regular basis. Modes considered active for the purposes of this study include walking, bicycling, scootering, skateboarding, and rollerblading. Inactive modes included car or personal vehicle, with children who take a bus being excluded from this study. From this definition of AST, two dependent variables were developed: (a) AST to school more than 50% of the total trips; (b) AST from school for more than 50% of the total trips.
Independent variables
Following the socio-ecological framework, this study uses three levels of independent variables that will be used as control variables: intrapersonal, interpersonal, and physical environment [41, 50]. Policy is controlled for by excluding all children who live outside of the walk zone of each school.
Intrapersonal variables were collected on both the parent and child surveys. Answers primarily come from the child surveys, with answers from the parent surveys being used when responses were missing. The variables used in this study are measured for each child: gender (i.e., child self-identifying as a girl [0] or boy [1]); and age (i.e., continuous measure of age in years).
Interpersonal variables were collected from parent or child surveys and measured for each child:
-
Parent Education: Parents (mother and father) self-identified no high school diploma (0), high school diploma (1), or post-secondary education (2). Completing any education past high school is considered post-secondary education.
-
Employment Status: Parents (mother and father) self-identified as being unemployed (0) or employed (1). Being employed includes employed full-time, employed part-time, while unemployed includes at home with children, unemployed, or student.
-
Siblings: Child self-identified the number of children living in their household, with one child represents no siblings (0) and many children represents siblings (1).
-
Number of Vehicles: parent self-identified the number of motor vehicles in their household, including not owning a vehicle (0), owning one vehicle (1), and owning 2 or more vehicles (2).
-
Median Family Income: Neighbourhood level median family income from the 2011 National Household Survey [51], measured by the census dissemination area in which a child’s home is located (i.e., home postal code).
The Physical Environment are measured in two ways:
-
Distance from home to school: the network distance in kilometres between home (i.e., home postal code) and school (i.e., point at centre of building footprint) were measured using the Network Analyst tool in ArcGIS 10.3 [52].
-
Level of urbanicity: Urbanicity refers to the urban form in which each child’s home is located, including suburban (0), urban (1), and rural (2). Urban is defined as the City of London boundary in 1961 (i.e., year suburbanization started). Suburban is defined as the remaining area within London. Rural includes all small towns and townships with a population under 100,000 (including agricultural land).
The rest of the independent variables used in this study are parent and child perceptions of barriers to AST. The questions, shown in Table 2, ask respondents to specify their level of agreement or disagreement on a four-point Likert-scale and responses were converted into binary variables for analysis: completely no and mostly no (0) and mostly yes and completely yes (1). Barriers are categorized into 4 themes: physical environment, safety, social, and individual/family preferences.

Statistical analysis
Two analyses were completed as part of this study to achieve the study objectives: chi-square tests and logistic regression. To achieve objective 1, chi-square tests for independence were completed in IBM SPSS Statistics 24 [53] to explore the relationship between parent and child responses to questions about perceptions of barriers. A chi-square test is applied when there are two categorical variables from a single population (parent and child perception of individual barriers) and is used to determine if there is a significant association between the two variables.
To achieve objective 2, a series of logistic regression models were computed in STATA SE 13 64bit [54]. Logistic regression has been chosen as it is more robust and does not have the assumptions (e.g., normal distribution, equal variance) many other binary type analyses include (e.g., logit, probit) [55]. Further, logistic regression parameter estimates can be converted into odds ratios, which are interpreted as the odds of success of the outcome variable over its failure [56]. All logistic regression models in this study included estimates for robust standard errors to account for clustering at the school level [57]. Logistic regression models were computed for both (a) to school AST and (b) from school AST using the following step-wise process: (1) Intrapersonal, interpersonal, and physical environment; (2) Model 1 + univariate barriers; (3) Model 2 + All significant univariate barriers for parents; (4) Model 3 + all significant univariate barriers for children. Statistical significance is reported based on critical value cut-offs of 0.05 and 0.01.
Results
Chi-Square analysis
The chi-square analysis comparing parent and child perceptions found a statistically significant difference in the distribution of every barrier (Table 3). This shows that parents and children have varying perceptions of barriers influencing a child’s journey to and from school, although it should be noted that there is still a high percentage of matching agreement or disagreement between parents and children (i.e., average of 77.3% of parents and children have matching agreement/disagreement). Trends of these varying perceptions can be seen within the four barrier themes, including physical environment, safety, social, and individual/family preferences.
Within the theme of physical environment perceptions of the barriers not enough bike paths and not enough trees on children’s routes to school have the largest differences of responses between parent and child. Most parents and children believe there are enough bike racks at the school and do not perceive this to be a barrier to AST. The remaining three themes saw larger discrepancies between child and parent perceptions of barriers. Parents perceived all safety related questions as barriers to their children’s AST, while children did not. The exception being the barrier unsafe for a child to walk with a friend, where parents and children held opposite responses compared to all other safety related barriers. Within the theme of social barriers, the largest variation of responses between parent and child was seen in bullying. Children did not see being bullied or teased as a barrier, while parents did. Finally, within the theme of individual/ family preferences children perceived more of these as barriers to AST than their parents. The exception being too much stuff to carry, with parents perceiving this as more of a barrier than children. These results demonstrate significant differences between parent and child perceptions of barriers, although, it is still unknown whether these perceived barriers influence the decision of children to use AST.

Intrapersonal, interpersonal, and physical environment factors
Following the social-ecological framework, a logistic regression model was conducted to understand how the intrapersonal, interpersonal, and physical environment factors influence AST for this sample (Table 4). Across all levels of the social-ecological framework, there is little difference between significant factors that influence the journey to school and from school. Age was found to be significantly related to an increase in the chances of children using AST. Multiple interpersonal factors found significantly related to a decrease in the odds of using AST both to and from school, including having siblings and more vehicles, while a mother being employed significantly increases the odds of using AST. Distance is related to AST both to and from school, with children living farther away decreasing the odds of choosing AST. The only variable that has different results between to and from school is urbanicity, where children living in urban areas have significantly lower odds of using AST when traveling to school than children living in suburban areas.
Univariate models
The univariate logistic regression models estimate the relationship between AST to and from school and each of the parent and child perceptions of the 19 barriers independently, while controlling for factors at the intrapersonal, interpersonal, and physical environment (Table 5). On the journey to school, parent’s perceptions of barriers explained AST more than children’s perceptions of barriers, particularly when examining safety and social influences. Parent’s perceptions of all safety and social barriers included in this univariate model are found to significantly impact children’s AST. Perceptions of barriers on the journey home from school showed opposite outcomes, with children’s perceptions of barriers explaining AST more than parent’s perceptions of barriers. Children’s perceptions of all barriers included in the univariate model except not enough trees and route is boring showed statistical significance. Similar to parent’s perceptions, results show that children’s perceiving barriers are less likely to use AST. Perceptions of safety have the greatest impact on AST behaviour to and from school for both children and parents.
Multivariate models
All barriers statistically significant in the univariate analysis were included in the final multivariate models, while controlling for intrapersonal, interpersonal, and physical environment factors. Results for the four final models are shown in Table 6, including AST to and from school for both parent and child perceptions.
There is variation between parent and child perceptions of barriers on the journey to school and the impact they have on AST. From the physical environment barriers parents perceive too far/ takes too much time as a barrier that negatively impacts children’s use of AST on their journey to school. Children perceive the physical environment barrier there are not a lot of trees along the streets in my neighbourhood to have a negative impact on their AST behaviours. Parent’s perceptions of safety barriers are explaining AST more than children’s perceptions of safety barriers on the journey to school. The safety barrier drivers speeding on the streets positively impacts children’s use of AST. From the social barriers, parents perceive the barrier of their children having no one to walk with to negatively impact children’s AST. Finally, both parents and children see the individual/ preference barrier more difficult to walk than drive as having a negative impact on AST a preference relating to their journey to school. In general, parent’s perceptions of barriers on the journey to school explain AST behaviours more than children’s perceptions of barriers.

Within this final model, parents and children did not perceive any physical environment barriers to impact children’s AST on the journey home from school. It feels unsafe because of crime is a safety barrier that children believe to negatively impact use of AST. From the social barriers, similar to the journey to school, parents perceive the barrier no one to walk with to negatively impact children’s AST. Finally, from the individual/ family preference barriers, parents perceive not fun to walk and too much stuff to carry to impact children’s use of AST on the journey home from school. As well, both parents and children see the barrier, more difficult to walk than drive to have a negative impact on AST. Parents and children’s perceptions of barriers share similarities between the journey to and from school however, more barriers are perceived to have an impact on AST on the journey home from school.
Discussion
This study compared parent and child perceptions of barriers and how they influenced children’s AST, while controlling for intrapersonal, interpersonal, and physical environment variables. Age, siblings, mothers occupational status, vehicle ownership, distance between home and school, and urbanicity were control variables found to impact children’s use of AST. In general, parents perceive more barriers to AST than children, although both parents and children perceptions have an impact on AST behaviour. There are also differences in the impact barriers have between the journey to school and home from school.
The intrapersonal, interpersonal, and physical environment variables are mostly consistent with previous research. At the intrapersonal level, age is found related to an increase in AST behaviour on the journey to and from school [58‐61] and there is no significant difference between boys and girls [10, 62]. There are multiple variables significant at the interpersonal level, as children are known to be largely influenced by the context of their family [63]. Children’s independent mobility, including AST, is associated with having siblings in both previous research and this study [64]. When children have employed mothers they have higher rates of AST, as children rely heavily on their mothers for transportation [11]. Having no car in the household is also related to an increase in AST, as these children really have few other options [11]. Interventions need to focus on getting children out of the car and into active modes, as congestion and vehicle emissions around the schools are the primary concerns for planning and transportation decisions [65].
There are also physical environment factors significantly related to AST, including distance and urbanicity. As in past research, distance between home and school is the strongest predictor of children’s AST [11, 39, 44, 66, 67], even when only examining those who live within walking distance of the school. Urbanicity is also found to significantly influence AST on the way to school, with children living in urban environments significantly less likely to use AST on the way to school compared to children living in suburban environments.

Findings show us that there is variation between parent and child perceptions of barriers on the journey to and from school and the impact they have on AST. The univariate analysis finds that parents perceptions of barriers explain AST more than children’s perceptions on the journey to school, while children’s perceptions of barriers are explaining AST more than parent’s perceptions for the journey home from school. A simple explanation of this finding can be that parents influence children’s travel modes in order to coordinate with parent’s work schedules [68]. Often parents are more involved with their child’s journey to school before or on their way to work, with dropping their child off at school as a part of their own getting to work route [69]. Children’s barriers are then more likely to impact behaviour on the journey home from school when its not part of a trip chain.
Physical environment barriers were found significant for the journey to school. Parents perceive the barrier too far/ takes too much time as significantly influential on decreasing children’s use of AST on the journey to school. Many parents go to work in the morning, so it is reasonable to assume that if they perceive their children’s journey as time consuming or too long, they see the time savings of driving a benefit compared to the extra time it takes to walk [68]. Children perceived not having enough trees as a physical environment barrier on the journey to school that negatively impacts their AST. Although previous finding in the literature about tree densities have mixed findings, the majority of research suggests that trees are positively associate with an increase in walking and that the presence of street trees are positively associated with children’s AST [8, 19, 44].
Barriers relating to safety had the most significant variables during the univariate analysis, but few have significant influence on children’s AST. The only safety barrier parent’s perceived as significantly influencing children’s journey to school was drivers speed on streets, which positively influence children’s use of AST. Drivers speeding related to an increase in AST is opposite to what was expected [70], meaning future research should examine the reason for this reverse perception. Although, past research examining barriers to active transportation has found those being active also perceive more safety barriers [71].
Children’s perceptions of social barriers to AST were not related to the journey to or from school; social barriers were only significant when perceived by parents. Parents perceive their child having no one to walk with as a barrier to AST on both the journey to and from school. Zhu and Lee [72] state that supportive peer influences have been found to increase children’s AST. Parents may feel uncomfortable allowing their child to walk alone; therefore, if they do not believe there is anyone for their child to walk with (e.g., friends, peers) they might not allow their child to walk to school. Multiple studies have found that girls who reported having friends in their neighbourhood were more likely to use AST [73, 74]. Although this study classifies no one to walk with as a social barrier, parents may perceive this as a way to mitigate safety barriers.
Individual/ Family Preferences is the last theme of barriers examined in this research. Parents perceive the barrier too much stuff to carry to negatively influence children’s use of AST on the journey home from school. This finding is intuitive in that children have the addition of homework, as well as other things collected throughout the school day to carry home. Parents should be aware of backpack recommendations and encourage their children to wear straps on both shoulders to avoid long-term risks associated with back pain [75]. Finally, findings were consistent for both parent and child perceptions that more difficult to walk than drive negatively impacts children’s use of AST to and from school. This is an important perception to target when designing interventions aiming to increase rates of AST. Children who do not use AST when they are able (i.e., live within walking distance) are missing out on the many benefits that come with this action. The PA that children are able to achieve while using AST can provide them with numerous physical, psychological, emotional, and behavioral health benefits [76].
Policy and practice
Findings from this study can be used to make recommendations for policy makers and practitioners. This research supports previous literature with results demonstrating that distance from home to school significantly influences children’s AST [77], even for student’s living within walking distance (1.6 km). This reiterates the importance of school siting decisions made by school boards, city planners, and developers [17, 44]. Shorter distance is a key influence on the mode children use to travel to and from school and should be considered by all those who have an input in deciding school locations and boundaries.
This research expands on the literature acknowledging the role children play in making decisions related to AST. Children and their parents often have varying perceptions of safety and their environments [33, 78]. Children’s positive perceptions are often associated with an increase in PA [79], and this research demonstrates the same with respect to perceptions of barriers and AST. How children’s perceive features they experience on their journey to and from school affects their decisions to use AST [78].
Successful interventions targeting levels of AST should consider influencers from all levels of the socio-ecological framework [80]. Research with a sole focus on the built environment as an intervention strategy will be insufficient in increasing AST since there is a wide range of factors that influence children’s decisions about AST. Integrating AST as a part of children’s daily routines is likely the most efficient intervention to raise children’s level of PA. Along with the involvement of children and parents, interventions should engage community partners across multiple stakeholder levels, as suggested within the socio-ecological framework [42]. The use of school travel planning (STP) is a preeminent intervention being used to promote children’s AST through collaborative public health strategies [16, 81‐83]. STP is a location specific, multi-sector intervention linking together key stakeholders with school communities to create safe environments in which more children can engage in AST [84]. Findings from this research provide key barriers that STP interventions should consider to increase the successfulness of the intervention. This research demonstrates that neighbourhood environments and the perceptions parents and children have of them, matter within the context of AST. Healthy, pedestrian friendly environments and how they are perceived are an important part of supporting and increasing children’s AST [85, 86]. Our study contributes to the growing body of literature on how perceptions of barriers within local environments can influence children’s AST.
Limitations and future work
One limitation of this study is AST is measured using data from a self-reported survey, which needs to be taken at face value despite potential biases (e.g., selective memory or exaggeration) [87, 88]. While objective measures, such as GPS tracking, would be preferred over self-report, the sample size of our study makes surveys a much more feasible way to collect AST outcome data. Another limitation of this study is the use of postal codes instead of exact home locations. This may cause slight variation within the estimations of the distance children travel from their home to school; however, previous studies indicate that postal codes are a reasonable proxy for home address in this region [89]. In the future, studies should use actual home locations, as well as GPS tracking to evaluate findings based on the actual routes children travel to and from school. Another limitation of this study is the use of self-reported measures of AST and inability to verify response accuracy. The inclusion of matched parent and child surveys allows for some validity checks, however a supplementary objective measure to avoid bias would be beneficial.
Future research should move beyond barriers and include perceptions of enablers experienced by children during AST to understand more features and the influence they may have on children’s journeys to and from school. As well, further research on perceptions of barriers to children’s AST needs to be completed using qualitative research methods. Although this study provides us with a deeper understanding of both parent and child perceptions of AST, a key finding is that that there is a difference between these perceptions. The decision to use AST is a complex one and can be influenced by multiple factors. It is possible that children may have other perceived barriers not asked on the survey, thus providing justification for the need of individualized qualitative research to design effective interventions at schools.
Conclusions
This study makes multiple contributions to the literature on children’s AST. We found that a combination of perceptions on environmental, safety, social, and preference barriers influence children AST. Our findings suggest that interventions used to promote AST should focus on safety, as well as perceptions of distance to break through habits of routinely getting driven to school. Interventions aiming to increase AST should include both parent and children in the process. Results from this study highlight that the relationships between PA levels and transport modes may vary within and across different populations and that AST initiatives should be tailored accordingly [10, 90]. This study contributes to the growing body of research of how local environments can influence children’s AST. Results show the importance in acquiring children’s perspectives when researching a topic involving them, as varying opinions can be seen between parents and their children. The importance of children’s perceptions and opinions should be valued because creating a safe and accessible environment for children is creating a healthy environment for all.
