BACKGROUND
The Park Rx study is a prospective, randomized controlled trial implemented within a federally qualified health center serving a low-income population in Washington, DC.
DESIGN AND SETTING
The 5-year randomized controlled trial will recruit 500 children, ages 6-16 to be randomized to receive either a park prescription (Park Rx) during routine clinical visits (intervention arm) or care as usual (control arm).
INTERVENTION
Park prescriptions promote both physical activity and exposure to nature. The prescription includes a place (i.e., park), an activity, a frequency, and a duration. Compared to usual care, we expect children receiving a park prescription will have greater physical activity levels and improved physical and mental health outcomes.
IMPLICATIONS
The results of the Park Rx trial will demonstrate the efficacy of the intervention and whether it will increase time spent in nature-rich areas (i.e., parks); have any biological impacts on health, including reducing hypercholesterolemia, hypertriglyceridemia, HbA1c, body mass index (BMI), and impact mental health, including stress and cognitive functioning.
TRIAL REGISTRATION
ClinicalTrials.gov identifier: NCT04114734. Registered on October 3, 2019.
背景
Park Rx 研究是一项前瞻性、随机对照试验，在一家为华盛顿特区低收入人群提供服务的联邦合格医疗中心内实施。
设计和设置
这项为期 5 年的随机对照试验将招募 500 名年龄在 6-16 岁的儿童，随机分为在常规临床就诊时接受公园处方（Park Rx，干预组）或常规护理（对照组）。
干预措施
公园处方既促进身体活动，又促进接触自然。处方包括一个地点（即公园）、一项活动、一个频率和一个持续时间。与常规护理相比，我们预计接受公园处方的儿童将有更高的身体活动水平和改善的身心健康结果。
意义
Park Rx 试验的结果将证明干预措施的有效性，以及它是否会增加在富含自然的区域（即公园）的时间；对健康有任何生物学影响，包括降低高胆固醇血症、高三酰甘油血症、HbA1c、体重指数（BMI），并影响心理健康，包括减轻压力和认知功能。
