Are park proximity and park features related to park use and park-based physical activity among adults? Variations by multiple socio-demographic characteristics.

BACKGROUND: Parks are valuable resources for physical activity (PA) given their widespread availability and low cost to maintain and use. Both proximity to parks and the availability of particular features are important correlates of PA. However, few studies have explored multiple measures of proximity simultaneously or the specific facilities associated with park use and park-based PA among adults, let alone differences across socio-demographic characteristics. The purpose of this study was to examine associations between park proximity and park facilities and adults' park use and park-based PA, while also exploring differences by gender, age, race, and income. METHODS: Data on monthly park use and weekly amount of PA undertaken in parks were collected via a mail survey of adults from randomly-selected households (n = 893) in Kansas City, Missouri (KCMO) in 2010-2011. Three measures of park proximity were calculated within 1 mile of participating households: distance to the closest park, number of parks, and total park area. All parks in KCMO were audited using the Community Park Audit Tool to determine the availability of 14 park facilities within 1 mile of each participant (e.g., trail, playground, tennis court). Multilevel logistic regression was used to examine the relationship between each of park use and park-based PA and 1) three measures of park proximity, and 2) the availability of 14 park facilities within 1 mile of participants. Separate analyses were conducted by gender, age, race, and income, while controlling for all socio-demographic characteristics and BMI. RESULTS: Across all sub-samples, distance to the closest park was not significantly related to either park use or park-based PA. However, numerous significant associations were found for the relationship of number of parks and amount of park space within 1 mile with both outcomes. As well, diverse facilities were associated with park use and park-based PA. For both park proximity and facilities, the significant relationships varied widely across gender, age, race, and income groups. CONCLUSIONS: Both park proximity and park facilities are related to park use and park-based PA. Understanding how such associations vary across demographic groups is important in planning for activity-friendly parks that are responsive to the needs of neighborhood residents.

Association of park size, distance, and features with physical activity in neighborhood parks.

OBJECTIVES: We studied whether park size, number of features in the park, and distance to a park from participants' homes were related to a park being used for physical activity. METHODS: We collected observational data on 28 specific features from 33 parks. Adult residents in surrounding areas (n=380) completed 7-day physical activity logs that included the location of their activities. We used logistic regression to examine the relative importance of park size, features, and distance to participants' homes in predicting whether a park was used for physical activity, with control for perceived neighborhood safety and aesthetics. RESULTS: Parks with more features were more likely to be used for physical activity; size and distance were not significant predictors. Park facilities were more important than were park amenities. Of the park facilities, trails had the strongest relationship with park use for physical activity. CONCLUSIONS: Specific park features may have significant implications for park-based physical activity. Future research should explore these factors in diverse neighborhoods and diverse parks among both younger and older populations.

Places to play: association of park space and facilities with healthy weight status among children.

The purpose of this study was to examine how healthy weight status among youth was related to (i) three proximity-based park variables: number of parks within 1 km of home, total area of parkland within 1 km, and distance to the closest park from home, and (ii) the availability of 13 specific park facilities within 1 km of the home. Data were collected from parents of children living in four neighborhoods of a medium-sized Canadian city. Logistic regression analyses revealed that none of the three proximity-based park variables was significantly associated with healthy weight status among children in the sample. However, when availability of the 13 park facilities was examined, children with a park playground within 1 km were almost five times more likely to be classified as being of a healthy weight rather then at risk or overweight compared to those children without playgrounds in nearby parks. Results suggest that availability of certain park facilities may play a more important role in promoting physical activity and healthy weight status among children than availability of park space in general. Implications for park design are discussed.
