Adkins (2004)16 52 F B USA 8- to 10-years CS, P There are playgrounds, parks and gyms nearby, it is safe to play outside (parent and child report) Objectively measured (accelerometer) physical activity No associations were identified between environmental attributes and physical activity.
Baranowski (1993)41 191 M/F B/W/H USA 3 and 4 years CS, O Month of the year (weather) Directly observed physical activity. Children were least active outdoors during the hottest months.
Boarnet (2005)39 62 M/F W/B/H/A USA Parents of children in 3rd – 5th grade (8–10 years) CS, O Installation of sidewalks, crossing signals, traffic control as part of a Safe Routes to School (SR2S) program. Parents' perceived change in child walking/biking to school Greater increases in perceived rates of children walking/riding to school for children who passed a completed SR2S zone compared to those who did not pass a zone.
Braza (2004)30 105 students from 34 schools M/F W/B/H/A USA 5th grade (ages 9 to 11 years)
Unit of analysis: schools
CS, O School size; population density; number of intersections per street mile in .5 mile buffer around school site. Data were obtained using Geographic Information Systems. Rates of walking and biking to school among students surveyed in each school Higher population density and a greater number of intersections per street mile were associated with higher rates of walking and biking to school in bivariate models.
Brodersen (2005)17 4320 M/F W/B/A England 11 to 12 years CS, O Area deprivation; number of sport pitches in borough; public spending on leisure facilities and open spaces; weather conditions. Self-reported days during past week child performed hard exercise that made him/her breathe heavily and sweat. Area deprivation (F) and total rainfall (F) were associated with lower physical activity. Colder temperatures (M) and number of sport pitches (F) were associated with higher physical activity.
Burdette (2005)48 3141 M/F W/B/H USA 3 years old CS, P Mothers' ratings of perceived neighborhood safety Mothers' reports of the average time per day their child played outdoors No associations between mothers' perception of neighborhood safety and their reports of the time their child spent playing outdoors
Carver (2005)18 347 M/F U Australia 12–13 years CS, P Parents' perceptions of good sports facilities for child, safe for child to walk/ride, good places for child to be active, traffic makes it difficult to walk. Child perceptions of ease to get around by bike, safety while walking/riding, roads safe, unattended dogs, strangers, fast food and convenience stores near home. Child self-reported frequency and duration of walking or cycling in the neighborhood (for recreation, transport, exercise, get to school). Adolescents walked or cycled more frequently when there were fewer unattended dogs (M, F), there were good places to be active (F), traffic was less problematic (M, F), there was lower perceived ease to cycle (M), there were more sport facilities in the area (M), the roads were perceived as safe(F), and convenience stores were further from home (F).

Cohen (2006)38 1554 F W/H/B/A USA 6th grade 12–13 years CS, O Distance to school along the shortest street network Objectively measured (accelerometer) physical activity A shorter distance to school was associated with greater MVPA during weekdays but not during the weekend
Dunton (2003)19 87 G W/H/A USA 14–17 years CS, P Perceived activity-related equipment in the home and activity-related resources in the community (e.g., park, gym, biking trail) Self-reported vigorous physical activity, total energy expenditure, and leisure time activity No associations were identified between activity-related resources in the home or the community and girls' self-reported physical activity.
Ewing (2004)33 726 people and 709 school trips surveyed U (gender) U(ethnicity) USA Students K-12th grade CS, O Estimated walk/bike time between destinations; proportion of street miles with street trees, bike lanes or paved shoulders, or sidewalks; sidewalk width; accessibility of attractions; neighborhood population density; school size Likelihood of walking or biking to school Students with shorter walk or bike times to school, and students traveling through areas with sidewalks on main roads were more likely to walk or bike to school. School size was not related to the likelihood of walking/biking to school.
Fein (2004)20 610 M/F W Canada Grades 9–12 Mean age 15.5 years CS, P Home environment; convenient facilities (park, bike trails, gym, skating rink); School environment (gym space, availability of exercise equipment, athletic facilities accessible). The perceived importance of each resource was also assessed. Self-reported physical activity Perceived convenience of facilities and perceived home, neighborhood, and school environment were significantly correlated with self-reported physical activity. The perceived importance of each of these constructs was also associated with higher physical activity.
Felton (2002)42 1668 F W/B USA 8th grade (approx age 13 years) CS, O Urban/rural residence Self-reported moderate and vigorous physical activity White girls living in urban areas and black girls in rural areas reported higher vigorous activity than their respective counterparts.

Self-reported moderate to vigorous physical activity Lower reported crime was associated with higher moderate to vigorous activity.
Hume (2005)34 127 M, F U Australia 10 year olds CS, P Children drew maps of their home and neighborhood environments. The frequency with which particular objects and locations were represented was coded including green space and outdoor areas and opportunities for physical activity in the neighborhood (e.g., playgrounds and facilities). Objectively measured (accelerometer) physical activity. Girls who drew a greater number of opportunities for physical activity in their neighborhood (e.g., the availability gyms, recreation and swimming centers, playgrounds) exhibited higher physical activity (specifically, low intensity physical activity).
Jago (2005)40 210 M W/B/H USA 10–14 years CS, O Ease of walking/cycling; tidiness of neighborhood; sidewalk characteristics; street access and conditions Objectively measured (accelerometer) physical activity. Sidewalk characteristics that foster walking (e.g., distance to curb, presence of trees as a buffer) were positively associated with light-intensity physical activity.
Molnar (2004)44 1378 M/F W/B/H USA 11 to 16 years CS, P, O Residents' perceived neighborhood safety and opportunities for children to play (P); social and physical disorder (O). Hours/week participated in recreational physical activity (parent report). More safe areas for children to play and lower social and physical disorder were associated with higher recreational activity.

Directly observed physical activity of students in each play area. Higher levels of activity were noted when equipment was available in outdoor play areas (F) when more permanent activity structures were available (M), and when such structures were available in combination with adult supervision (F).
Sallis (2002)28 781 M/F W (75%) USA Grades 1–12 (ages 6–18) CS, P Safe to play outdoors; access to parks/playgrounds; distance to park; safety of nearest park. Parents' reports of children's physical activity and objectively measured (accelerometer) physical activity (N = sub sample of 200) Among girls in grades 10–12, parents' perception of neighborhood safety was associated with higher physical activity. Among girls in grades 7–9, parents' perception of park safety was negatively associated with children's physical activity.
Sirard (2005)47 Unit of analysis = school (N = 8) USA Elementary schools CS, O School urbanization and weather conditions. Rates of walking and cycling to school for each school. No associations between environmental variables and active commuting were identified.
Stratton (2005)29 99 M/F U Wales and England 4–11 years I, O Intervention in which school playgrounds were painted with murals, hopscotch, fun trails, snakes and ladders, and court markings (e.g., lines for basketball). Heart rate telemeters were used to assess heart rate during physical activity and converted to represent MVPA and VPA. In comparison to control schools, time spent in MVPA and VPA increased significantly in intervention schools as a result of playground painting.
Stucky-Ropp (1993)31 240 M/F W USA 5th and 6th grade Mean age: 11.2 ± .7 CS, P Number of exercise-related items at home Self reported physical activity A greater number of exercise-related items in the home was associated with higher physical activity among girls but not boys.

Timperio (2004)24 1200 M/F U Australia 5–6 years and 10–12 years. CS, P Traffic density, road safety, strangers, sporting facilities, and public transportation (parent report). Children 10–12 years also reported on perceived traffic, road safety, strangers, and sport facilities. Walking/riding to particular destinations (e.g., friend's house, park, school) 3 or more times/week (parent report) Among 5–6 year olds, parents' perception of heavy traffic (M), and limited public transportation (F) were associated with lower walking/cycling among children. Among 10–12 year olds, youth who perceived no parks nearby (M, F) and whose parents believed that they had to cross many roads to get to play areas (M, F), that there were no lights or crossings (M), that there were few sporting arenas (F), and that there was limited public transportation (F) were less likely to bicycle/walk.
Timperio (2006)36 912 M/F U Australia 5–6 years and 10–12 years CS, O Distance to school, busy-road barrier, route along busy road, pedestrian route directness (connectivity), steep incline Walking or riding to school (parent report) In both age groups, children were less likely to actively commute to school if their route as >800 m and a busy route barrier was present en route. Children with a steep incline (5–6 year olds) and a direct route to school (10–12 year olds) were less likely to actively commute
