Recreational and transportation infrastructure can promote physical activity among children and adolescents. The Play Across Boston community-based research project sought to estimate and compare playground renovation rates across Boston areas before and after a playground quality assessment, to describe changes in playground quality among a subset of parks, and to document features of local transportation infrastructure around parks.
We used an observational pretest-posttest design to estimate playground renovation rates among 103 city-operated parks. Renovation rates were calculated on the basis of annual city Parks Department capital budgets from fiscal years 1996 through 2007. We used the same design to describe changes between a 2000 to 2001 baseline assessment of playground quality and a 2007 follow-up measured via observation of a subsample of 18 low-scoring parks in disadvantaged areas. We used
Overall playground renovation rates before (29%) and after (34%) baseline assessment were similar. Parks scoring low on playground quality at baseline were renovated after baseline at a higher rate than high-scoring playgrounds. After accounting for baseline playground quality, parks in disadvantaged areas were renovated at a rate similar to those in other areas. Playground quality scores improved between baseline (mean, 38.3; 95% confidence interval, 35.3-41.3) and 2007 in a subsample of previously low-scoring parks in disadvantaged areas.
The findings of the 2007 follow-up assessment indicate an equitable rate of playground renovation across city areas according to need.
Physical activity among children and adolescents can provide lifelong health benefits. Compared with their inactive peers, physically active children and youths have better cardiorespiratory endurance and muscular strength, less body fat, better cardiovascular and metabolic risk factor profiles, stronger bones, and better mental health (
Features of the built environment can promote physical activity and improve health (
Transportation infrastructure is also associated with physical activity among youths (
Since 1999, the Play Across Boston (PAB) project has worked with community partners to document youth sports and physical activity resources in Boston and to monitor ongoing citywide efforts in reducing documented disparities in access to physical activity facilities and increasing program participation. PAB is a project of the Harvard Prevention Research Center at the Harvard School of Public Health undertaken in collaboration with Northeastern University's Center for the Study of Sport in Society and a broad-based community advisory board. The background of PAB and that of the community process facilitating project development and implementation are described in detail elsewhere (
Beginning in the summer of 2001, assessment findings were disseminated to community leaders to facilitate data-driven action for reducing observed disparities in opportunities for physical activity among youths in disadvantaged neighborhoods (
This study used an observational pretest-posttest design with no control arm: 1) to estimate citywide playground renovation rates from fiscal year (FY) 1996 to FY 2007 and 2) to describe changes in playground quality among a subsample of public parks in an area of socioeconomically disadvantaged neighborhoods between a 2000 to 2001 baseline assessment and an August 2007 follow-up. This study also used a cross-sectional design to describe features of local bicycle and pedestrian transportation infrastructure surrounding the parks in the subsample.
The setting for this study was Boston, Massachusetts. In the 2000 US Census, Boston had 589,141 residents, 116,559 (20%) of whom were younger than 18 years. Among these youths, 37% were black, 25% white, 24% Hispanic, 7% Asian, and 6% of another race/ethnicity. Twenty-three percent of families with children younger than 18 years had household incomes below the poverty level (
All 103 public parks operated by the Boston Parks and Recreation Department (Parks Department) that were assessed for playground quality at the PAB baseline were eligible for this study. Forty-two parks that were assessed for playground quality at the PAB baseline were not eligible because they were operated by other city or state agencies.
The city public health agency and community partners have worked with 7 of Boston's 16 neighborhoods to address health promotion around chronic disease risk factors, including physical activity, through the Boston Steps program, funded by the Centers for Disease Control and Prevention, and the Boston Collaborative for Food and Fitness, funded by the W.K. Kellogg Foundation. These 7 neighborhoods are collectively referred to as the "disadvantaged area" in this study. More than two-thirds (69%) of Boston youths live in this disadvantaged area (
Of the 103 eligible parks, 59 were in the disadvantaged area. For follow-up assessment of playground quality we selected all parks located in the disadvantaged area that had a baseline playground quality score lower than 50 (n = 19). We considered playgrounds scoring below 50 (n = 24 citywide) to be low-scoring playgrounds in need of repairs or renovations. Of the 19 parks selected for the subsample, 1 park was not assessed in 2007 because of ongoing renovations, resulting in a subsample total of 18 parks for analysis.
We reviewed Parks Department capital budgets from FY 1996 through FY 2007 to estimate citywide playground renovation rates among the park sample. We obtained annual capital budgets from the city of Boston website (
After identifying playground renovations, we calculated renovation rates for the 6-year periods before (FY 1996-FY 2001) and after (FY 2002-FY 2007) the PAB baseline assessment. The renovation rate in each period equaled the total number of parks renovated in the period divided by the total number of parks in the sample. We used 6-year rates instead of annual rates because some renovation projects spanned multiple budget years.
Researchers conducted a follow-up assessment of parks to assess improvement in playground quality from baseline to follow-up. A research assistant (J.L.B.) visited a subsample of parks during August 2007 and assessed playground quality by using the same playground quality instrument used in the baseline assessment. This instrument (
During the assessment of playground quality in August 2007, the same research assistant also assessed bicycle and pedestrian access around the subsample of parks. The purpose of this assessment was to pilot-test a tool for assessing infrastructure features around parks and to investigate features potentially influencing access to public parks. Using an instrument adapted from existing tools (
We used the McNemar test to compare overall renovation rates before and after baseline among the parks sampled and
We performed a new analysis of baseline playground quality scores to calculate the mean score in the follow-up park sample and to compare scores by city area using a
Parks Department capital budgets documented that 62 of the 103 Parks Department-operated playgrounds assessed in the PAB baseline assessment were renovated in the 12-year period from FY 1996 through FY 2007 (
Parks in the disadvantaged area had lower overall baseline playground quality scores compared with parks in other city areas (
Bicycle and pedestrian access scores suggest that, on average, these parks met standards for approximately half of the items assessed (mean, 52.3; 95% confidence interval, 47.7-56.9) (
In previous findings from the 2000 to 2001 baseline assessment, neighborhoods with lower playground quality scores also tended to have fewer playgrounds in proportion to youth population (
Results from the follow-up observational assessment corroborate findings regarding playground renovations. Many of the playground quality items that improved between the baseline and follow-up assessments were related to playground equipment construction, suggesting that newer installations are meeting more stringent safety standards. The playground quality items that continued to have low compliance were largely related to maintenance issues, such as upkeep of safety surfacing and attention to broken or missing equipment.
Findings regarding bicycle and pedestrian access offer a starting point for further dialogue and collaboration to provide and improve local bicycle and pedestrian access to these playgrounds and parks, which are destinations for children and adults alike. Overall, pedestrian access appeared better than bicycle access around the parks assessed. Road lighting and sidewalks, basic infrastructure associated with reductions in pedestrian injuries (
Several limitations to this study should be noted. The study was conducted in 1 city by using an observational design without a comparison community. Therefore, we cannot account for natural history, particularly with respect to the overall economic climate and the lifespan of playgrounds. We did not know the age of each playground at baseline, which would likely influence observed playground quality and renovation scheduling, because we lacked detailed capital budget data before FY 1996. Analyses of playground renovations after baseline were limited by small sample size and produced wide confidence intervals; point estimates should be interpreted with caution. The measure used to determine playground renovation rates was not assessed for reliability or validity. We lacked detailed project descriptions and did not confirm project construction dates through discussion with city officials or through direct observation, except among the subsample of parks observed. We also did not examine other funding sources for playground renovations, which could vary by park location. Future studies could compare playground renovation history across communities, validate the method for identifying playground renovations by using city Parks Department capital budgets, and investigate other sources of park renovation funding.
For observational assessments, results are representative only of playgrounds in the disadvantaged area that had low observed playground quality at baseline. Because of resource limitations, we were not able to observe playground quality or bicycle and pedestrian access citywide or make comparisons by city area or baseline quality with sufficient power. A comprehensive assessment of all Boston playgrounds is needed to describe citywide changes in playground quality. In the playground quality instrument used, items contribute equally to the playground score, so the same score for 2 different parks or for the same park at baseline and follow-up may not reflect equivalent injury hazard. At follow-up, 1 researcher (J.L.B.) completed all playground quality assessments, whereas at baseline 5 researchers (including C.H. and A.L.C.) assessed quality. However, 1 researcher (A.L.C.) assessed 64% of parks at baseline, and the instrument demonstrated good interrater reliability (
One of many ways to promote physical activity and health among children and youths is through provision of accessible, quality recreational infrastructure, including playgrounds. In this study, data from Parks Department capital budgets indicate an equitable rate of playground renovation across city areas according to need, as observed and communicated through the PAB community-based research project.

Source of all data is Boston Parks and Recreation Department capital budgets, fiscal year 1996 through fiscal year 2007. A baseline playground assessment was performed by Play Across Boston in 2000 to 2001; not all city parks included in the assessment were included in this study.
The playground renovation rate is the number of parks renovated at any point during 1996-2001 or during 2002-2007 divided by the total number of parks.
Total playgrounds renovated during 1996-2001 and during 2002-2007 do not sum to total playgrounds renovated during 1996-2007 (n = 62) because 3 parks were renovated during both time periods.
Disadvantaged areas were 7 neighborhoods targeted by the city public health agency. Other city areas were all other neighborhoods.
The baseline playground quality score is the proportion of items that complied with safety standards for climbing equipment, swings, sandboxes, and spray pools and ease of supervision of children in play areas.
