Abstract

Introduction: Most youth do not achieve recommended levels of physical activity (PA), so finding methods to increase PA would be beneficial to health. The objective of this study was to determine if clinician prescriptions for park visits would increase PA among youth.

Study design: This randomized clinical trial (RCT) was conducted from 2020-2023 with 12-months follow-up.

Setting/participants: This RCT was conducted in a Federally Qualified Health Center outpatient clinic in Washington, DC and focused on youth ages 6-16 with one or more diagnoses of chronic conditions that usually require two or more routine health care provider visits per year.

Intervention: Receiving park prescriptions from their health care provider during regular clinic visits, about every 3 months.

Main outcome measures: Accelerometry-measured minutes of moderate-to-vigorous physical activity (MVPA), BMI, blood pressure (BP) and self-report of park visit frequency and time spent in park were measured.

Results: Of the 514 randomized participants, the median age was 10.4 yrs (SD 2.7) and included 246 females (47.9%), 268 males, (52.1%) 451 Latinx (87.7%), and 52 African Americans (10.1%). Intent-to-treat analyses showed a significant change of daily MVPA, increasing 2.03.

公园rx随机对照试验（rct）：对青少年身体活动（pa）的影响。

大多数年轻人没有达到推荐的身体活动水平（PA），因此找到增加PA的方法将有利于健康。本研究的目的是确定临床医生处方公园参观是否会增加青少年的PA。研究设计：本随机临床试验（RCT）于2020-2023年进行，随访12个月。背景/参与者：该随机对照试验在华盛顿特区的一家联邦合格健康中心门诊诊所进行，主要针对6-16岁的青少年，他们被诊断患有一种或多种慢性疾病，通常每年需要两次或两次以上的常规医疗服务提供者就诊。干预措施：大约每3个月，在定期诊所就诊期间，从他们的卫生保健提供者那里获得公园处方。主要观察指标：测量受试者的中高强度体力活动时间（MVPA）、身体质量指数（BMI）、血压（BP）以及公园访问频率和公园停留时间的自我报告。结果：在514名随机参与者中，中位年龄为10.4岁（SD 2.7），包括246名女性（47.9%），268名男性（52.1%），451名拉丁裔（87.7%）和52名非洲裔美国人（10.1%）。意向治疗分析显示每日MVPA变化显著，增加2.03。

It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health. Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published.
