摘要

公园是促进青少年定期体育活动的建筑环境的一个组成部分。本研究调查了在种族或民族多元化社区中,基于人口统计学和公园特征的年轻人基于公园的PA的差异。2017-2018年,公园选择在北卡罗来纳州(n = 6)和纽约州(n = 6)的亚裔(n = 3)、拉丁裔(n = 5)和黑人(n = 4)社区。研究人员招募了5-10岁儿童的父母或看护人参与。儿童佩戴Actigraph GT3 +腰部加速度计和QStarz GPS装置,并被指示正常玩耍至少15分钟。Evenson分割点用于将PA水平分为久坐、轻度、中度和剧烈。使用卡方检验和非参数Kruskal-Wallis检验来检查不同研究地点和人口变量的PA强度分钟(久坐、轻度、中度至剧烈)的差异。来自纽约(n = 200)和NC (n = 157)的青年参与。总体而言,以公园为基础的PA以轻度强度为主(59.9%),其次是中度至剧烈强度(32.4%)。与男性参与者相比,女性花在久坐行为上的时间更多(9.0%,6.1%),而花在中度到剧烈运动上的时间更少(26.6%,38.1%)。被认为是黑人(32.9% MVPA)、拉丁裔(35.8%)和其他(39.8%)的参与者比亚洲(26.6%)和非西班牙裔白人(21.3%)的参与者花在中度到剧烈PA上的时间百分比更高。中等到剧烈的PA比例最高的地方是秋千架(46%)和篮球场(45%)。种族和民族、性别和活动区域的差异表明,不同的青少年对公园的使用方式不同;在设计适合不同年龄和背景的公园时,应该考虑这些因素。

Use of Accelerometry and Global Positioning System (GPS) to Describe Children's Park-Based Physical Activity Among Racial and Ethnic Minority Youth.

Parks are one component of the built environment to promote regular physical activity (PA) among youth. This study investigated differences in park-based PA among youth based on demographics and park features in racially or ethnically diverse communities. In 2017-2018, parks were selected in majority Asian (n = 3), Latino (n = 5), and Black (n = 4) neighborhoods in North Carolina (n = 6) and New York (n = 6). Researchers recruited parents/caregivers of 5-10-year-olds to participate. Children wore an Actigraph GT3 + waist accelerometer and a QStarz GPS unit and were instructed to play normally for at least 15 min. Evenson cut-points were used to classify PA levels as sedentary, light, moderate, and vigorous. Chi-squared tests and non-parametric Kruskal-Wallis tests were used to examine differences in PA intensity minutes (sedentary, light, moderate-to-vigorous) across study location and demographic variables. Youth participated from NY (n = 200) and NC (n = 157). Overall, most park-based PA was spent in light intensity (59.9%), followed by moderate-to-vigorous intensity (32.4%). Females, compared to male participants, spent more time in sedentary behavior (9.0%, 6.1%) and less time in moderate-to-vigorous PA (26.6%, 38.1%). Participants who identified as Black (32.9% MVPA), Latino (35.8%), and Other (39.8%) spent higher percentages of time in moderate-to-vigorous PA than Asian (26.6%) and non-Hispanic White (21.3%) participants. The highest proportion of moderate-to-vigorous PA occurred on swing sets (46%) and basketball courts (45%). Racial and ethnic, sex, and activity area differences in park-based PA indicate that diverse youth use parks uniquely; these factors should be considered in designing parks for various ages and backgrounds.

期刊介绍: The Journal of Urban Health is the premier and authoritative source of rigorous analyses to advance the health and well-being of people in cities. The Journal provides a platform for interdisciplinary exploration of the evidence base for the broader determinants of health and health inequities needed to strengthen policies, programs, and governance for urban health. The Journal publishes original data, case studies, commentaries, book reviews, executive summaries of selected reports, and proceedings from important global meetings. It welcomes submissions presenting new analytic methods, including systems science approaches to urban problem solving. Finally, the Journal provides a forum linking scholars, practitioners, civil society, and policy makers from the multiple sectors that can influence the health of urban populations.
