Local parks are an important community resource that may influence levels of physical activity among youth. However, few population-based studies have investigated park-based physical activity among youth.
This study examines sociodemographic, family, and neighborhood characteristics associated with park-based physical activity among adolescents.
Data were from the 2007 California Health Interview Survey (CHIS), a population-based survey of California households, and were analyzed in 2012-2013 and 2015. This study examined individual (age, gender, race/ethnicity, and nativity), family (household income, parental education, and nativity), and neighborhood characteristics (urbanicity, perceived park availability, perceived park safety, neighborhood income, and racial composition) associated with engaging in park-based physical activity among adolescents.
In California, 71% of adolescents reported being physically active the last time they visited a park. In adjusted multinomial logistic regression analyses, older adolescents and females were less likely to be physically active in parks. Adolescents with a park within walking distance of home and those with a safe park nearby were more likely to be physically active during a park visit.
Park availability and perceptions of park safety are important predictors of engaging in park-based physical activity among adolescents. These findings provide information that can help inform interventions intended to increase physical activity among youth. Strategies that increase availability and safety of parks and other recreation spaces may be particularly effective.
城市公园是一项重要的社区资源，可能会影响青少年的身体活动水平。然而，很少有基于人群的研究调查青少年在公园内的身体活动情况。
本研究探讨与青少年在公园内进行身体活动相关的社会人口学、家庭和邻里特征。
数据来自2007年加利福尼亚健康访谈调查（CHIS），这是一项对加利福尼亚家庭进行的基于人群的调查，并在2012 - 2013年和2015年进行了分析。本研究考察了与青少年在公园内进行身体活动相关的个体特征（年龄、性别、种族/民族和出生地）、家庭特征（家庭收入、父母教育程度和出生地）以及邻里特征（城市化程度、感知到的公园可及性、感知到的公园安全性、邻里收入和种族构成）。
在加利福尼亚州，71%的青少年报告称他们上次去公园时进行了身体活动。在调整后的多项逻辑回归分析中，年龄较大的青少年和女性在公园内进行身体活动的可能性较小。家附近有公园且附近有安全公园的青少年在公园游玩期间进行身体活动的可能性更大。
公园的可及性和对公园安全性的感知是青少年在公园内进行身体活动的重要预测因素。这些发现提供了有助于为旨在增加青少年身体活动的干预措施提供信息的内容。提高公园和其他休闲空间的可及性和安全性的策略可能特别有效。
