The Effects of Park-Based Interventions on Health-Related Outcomes Among Youth: A Systematic Review

Abstract

Objective The purpose of the study is to present a comprehensive systematic review of the effects of park-based interventions on health outcomes among youth, defined as children and adolescents. Data Source Web of Science, MEDLINE, and Scopus databases searched through November 2020. Study Inclusion and Exclusion Criteria Interventions conducted in publicly accessible parks that evaluated health outcomes (i.e., physical, mental, and emotional); focused on children and adolescents (up to 18 years old, or up to 22 years old for individuals with developmental needs); and was published in English, Spanish, and Chinese. Data Extraction Two independent reviewers extracted data and assessed the quality of the 15 included studies using the Guide to Community Preventive Services tool. Data Synthesis Descriptive summary of study characteristics and summarized methodological quality of the studies. Results Twelve studies were person-based interventions involving the evaluation of health outcome changes in cohorts, and the remaining studies were park-based, focused on changing the park environment and observing changes in youth participation in parks. All identified interventions were positively associated with individual-level and park-level outcomes ranging from body weight, moderate-to-vigorous-intensity physical activity, park utilization, and health behavior knowledge. Conclusions This systematic review demonstrated that parks as sites of interventions can provide an environment that promotes health and wellbeing for youth. Nevertheless, the number of relevant studies were limited, thus it is important to leverage and expand on existing knowledge of the utility of parks as sites of intervention to address health concerns at this critical juncture of the life course.

Greenspaces and Health: Scoping Review of studies in Europe

“…Behaviors explored included first and foremost users and uses (such as the number of park visitors, types of activities and when greenspaces are used), as well as physical activity and the use of park and mobility infrastructure. With regards to behaviour change, public parks can serve as effective settings for interventions targeting youth to improve physical, mental, and emotional health outcomes [ 53 ]. Playground use and physical activity levels of youth in deprived neighbourhoods can be increased by promoting larger numbers of children to play through tailoring the design of playgrounds to include innovative designs, lendable sports material, and sports guidance in a safe environment [ 14 , 85 , 86 ].…”
