Promoting physical activity in high-poverty neighborhood parks: A cluster randomized controlled trial.

ABSTRACT: Although physical activity can help mitigate or prevent multiple chronic diseases, most people in the U.S., especially high-poverty minority groups, engage in insufficient levels of physical activity. To test ways to promote more physical activity in high-poverty area public parks we conducted a randomized controlled intervention trial. After completing baseline measures of park-based physical activity using systematic direct observation three times/day each month for six months and assessing preferences for park programming among 1445 residents living within 1 mile of study parks, we randomized 48 parks in high poverty neighborhoods in the City of Los Angeles, California during 2013-2014 to four study arms: 1) free physical activity classes over a 6-month period, 2) a frequent user program where participants could win prizes based upon the number of visits they made to the park, 3) both the programs, and 4) neither one (control condition). We re-measured park use in 2014-2015 using the same methods during the six months the intervention programs were in operation. A total of 2047 free park classes were offered attracting 16,718 participants. The frequent user programs enrolled 1452 individuals and prizes were awarded to 830. Residents in the two study arms with free classes were more likely to report being aware of and participating in park-based physical activity programs; however, overall observed park-based physical activity increased similarly across all study arms. The process evaluation uncovered several barriers to program implementation, including inconsistent scheduling of classes, partly due to safety concerns among instructors. Multiple social factors interfere with leisure time physical activity among low-income populations, suggesting modest interventions may be insufficient to overcome these issues. Although new park programs can attract users, new programs alone may be insufficient to increase overall park use in low-income neighborhoods at times when the programs are not taking place.

Project description:BACKGROUND:Physical activity (PA) has demonstrated a decreased risk in various cancers and other chronic diseases; however, rural residents are less likely to attain recommended levels of PA compared to urban and suburban counterparts. Given rural residents make up 15% of the United States population, there is a need for novel approaches to increase PA among this population. The goal of the present study is to investigate the effectiveness of a multilevel intervention to increase PA rates among rural residents. METHODS/DESIGN:Guided by an ecological framework, a group-randomized design will be used to evaluate the effects of a three-level intervention for increasing PA among adult residents residing in 6 rural communities (n = 600) along with 6 control communities (n = 600). The intervention includes components at the individual (short message service [SMS] text messages), interpersonal (social support in walking groups), and community levels (events at existing trails). Innovative methods to encourage participation will be employed as well as a focus on life priorities (family, recreation, hobbies) other than health. Aim 1 includes a literature review and key informant interviews to determine the local contexts for intervention adaptation. Aim 2 will employ a set of interventions at the individual, interpersonal, and community-levels to evaluate their impact on moderate-to-vigorous PA as measured by self-reported (telephone survey) and objectively assessed (accelerometry) measures. These data are supplemented by location based on Global Positioning System and community audits, which provide information on recreational amenities, programs/policies, and street segments. DISCUSSION:This study is among the first of its kind to test a multilevel intervention in a rural setting, address life priorities that compliment health outcomes, and examine moderation between behavioral interventions and the natural environments where people are physically active. Our results will influence the field by enhancing the ability to scale-up innovative, PA interventions with the potential to reach high-risk, rural populations.

Project description:IntroductionUrban neighborhood parks are designed to provide easy access to recreation and physical activity. We analyzed data from the first National Study of Neighborhood Parks, which assessed the characteristics and use of a representative sample of U.S. urban neighborhood parks. This article compares factors associated with active commuting (e.g., walking) to parks among men and women and park characteristics associated with observed moderate-to-vigorous physical activity (MVPA) within neighborhood parks.MethodsWe used systematic direct observation to quantify parks visitors of all ages in 162 U.S. neighborhood parks in 25 cities in 2016 and surveyed a sample of adult visitors (877 women and 793 men). We used descriptive statistics to identify park facilities, amenities, and park management practices associated with park use. We also conducted multivariate regressions to identify factors most closely associated with observed park-based MVPA among all age groups and with self-reported levels of active commuting to parks among adults.ResultsReasons to visit parks varied by gender, with women more likely than men to bring children (59% vs 42% for men; p < .001), and men more likely than women to go to parks to relax (38% vs 29%; p = .01). Bringing children to parks was associated with more motorized transport among women, but not among men. Active commuting to parks was associated with living closer to parks (β = -0.92; p < .0001), a greater frequency of park use (β = 0.99; p < .0001), and the park having a working drinking fountain (β = 0.62; p = .01), with no significant differences between men and women. Men and boys used park facilities very differently than women and girls. Men and boys engaged in the most MVPA in soccer fields, gyms, and skate parks, whereas for women and girls the top three sites were pools, playgrounds, and walking paths.ConclusionsSignificant gender differences in why men and women visit parks and how parks are used likely reflect cultural determinants of gender roles. Our findings suggest that park management practices should be adjusted to mitigate the lower use of parks and lower levels of park-based MVPA among women and girls compared with men and boys.

Project description:BackgroundPhysical activity is beneficial for cardiovascular rehabilitation. Digitalization suggests using technology in the promotion of physical activity and lifestyle changes. The effectiveness of distance technology interventions has previously been found to be similar to that of conventional treatment, but the added value of the technology has not been frequently studied.ObjectiveThe aim of this pilot study was to investigate whether additional distance technology intervention is more effective in promoting physical activity than non-technology-based treatment in 12 months of cardiac rehabilitation.MethodsThe cardiovascular disease rehabilitation intervention consisted of three 5-day inpatient periods in a rehabilitation center and two 6-month self-exercise periods at home in between. Participants were recruited from among cardiac patients who attended the rehabilitation program and were cluster-randomized into unblinded groups: conventional rehabilitation control clusters (n=3) and similar rehabilitation with additional distance technology experimental group clusters (n=3). Experimental groups used Fitbit Charge HR for self-monitoring, and they set goals and reported their activity using Movendos mCoach, through which they received monthly automated and in-person feedback. Physical activity outcomes for all participants were measured using the Fitbit Zip accelerometer and the International Physical Activity Questionnaire.ResultsDuring the first 6 months, the experimental group (n=29) engaged in light physical activity more often than the control group (n=30; mean difference [MD] 324.2 minutes per week, 95% CI 77.4 to 571.0; P=.01). There were no group differences in the duration of moderate to vigorous physical activity (MD 12.6 minutes per week, 95% CI -90.5 to 115.7; P=.82) or steps per day (MD 1084.0, 95% CI -585.0 to 2752.9; P=.20). During the following 6 months, no differences between the groups were observed in light physical activity (MD -87.9 minutes per week, 95% CI -379.2 to 203.3; P=.54), moderate to vigorous physical activity (MD 70.9 minutes per week, 95% CI -75.7 to 217.6; P=.33), or steps per day (MD 867.1, 95% CI -2099.6 to 3833.9; P=.55).ConclusionsThe use of additional distance technology increased the duration of light physical activity at the beginning of cardiac rehabilitation (for the first 6 months), but statistically significant differences were not observed between the two groups for moderate or vigorous physical activity or steps per day for both 6-month self-exercise periods.Trial registrationISRCTN Registry ISRCTN61225589; https://doi.org/10.1186/ISRCTN61225589.

Project description:BACKGROUND:Programs promoting population health through physical activity (PA) and exposure to nature are popular, but few have been evaluated in randomized-controlled trials (RCTs). OBJECTIVE:To investigate the effectiveness of a park prescription intervention (PPI) for improving total moderate-to-vigorous PA (MVPA), other PA related behaviors, quality of life (QoL) and cardio-metabolic health among adults. METHODS:Healthy individuals aged 40 to 65?years were recruited through community health screenings and randomly assigned to 1) PPI: face-to-face Park Prescription + invitation to weekly exercise sessions in parks, or 2) control: standard PA materials. After the six-month intervention, participants completed accelerometer assessments, questionnaires on health behaviors and QoL, and health screenings. Independent sample t-tests were used to compare outcomes between groups, with secondary analysis adjusted for co-variates via multiple linear regression. A p-value <0.05 was considered statistically significant. RESULTS:Eighty participants were allocated to each group. Participants with mean age of 51.1 (Standard Deviation: 6.3) years were predominantly female (79%) and of Chinese ethnicity (81%). Participation in the group exercise started at 48% and declined to 24% by week 26. At six-months, 145 (91%) participants attended health screenings for outcome measure collection, and 126 (79%) provided valid accelerometer data. Time spent in MVPA favored the PPI group but this difference was not statistically significant (4.4 (-?43.8, 52.7) minutes/week; when removing 2 extreme outliers 26.8 (-?9.7, 63.4) minutes/week). Time spent in parks (147.5 (2.1, 292.9) minutes/month), PA in parks (192.5 (59.5, 325.5) minutes/month), and recreational PA (48.7 (1.4, 96.0) minutes/week) were significantly greater in the PPI group. PPI also significantly improved psychological QoL (4.0 (0.0, 8.0). DISCUSSION:PPI improved park use, PA in parks, recreational PA, and psychological QoL but not total MVPA. Future RCTs' are warranted to investigate PPI in different target populations and to provide further evidence for improvements in health outcomes.
