The availability of places to engage in physical activity may influence physical activity levels. This study examined whether the relationship between physical activity and access to parks differs depending on adolescents' sociodemographic, housing, and neighborhood characteristics.
Data were analyzed from 4010 adolescents who responded to the 2003 California Health Interview Survey (CHIS). Analyses were conducted in 2005-2006. Five sets of logistic regressions were conducted to examine the relationship between physical activity and access to a safe park among adolescents living in (1) urban versus rural areas; (2) apartment buildings versus houses, (3) neighborhoods perceived as unsafe versus safe; (4) lower- versus higher-income families; and (5) adolescents who were Latino, African American, Asian, or white. Analyses also examined interactions between park access and these factors.
Access to a safe park was positively associated with regular physical activity and negatively associated with inactivity for adolescents in urban areas, but not rural areas. Additionally, adolescents with access to a safe park were less likely to be inactive than those without access among those living in (1) apartment buildings, (2) unsafe neighborhoods, and (3) lower-income families. Park access was not associated with regular physical activity for these groups. The association between park access and physical activity varied by race/ethnicity.
These findings suggest that the relationship between physical activity and access to parks differs depending on adolescents' sociodemographic, housing, and neighborhood characteristics, and that parks may be particularly important for promoting physical activity among urban adolescents.
进行体育活动场所的可及性可能会影响体育活动水平。本研究探讨了体育活动与公园可及性之间的关系是否因青少年的社会人口统计学特征、住房情况及邻里特征而异。
对4010名回应2003年加利福尼亚健康访谈调查（CHIS）的青少年的数据进行分析。分析于2005 - 2006年进行。进行了五组逻辑回归分析，以研究居住在以下情况的青少年中体育活动与安全公园可及性之间的关系：（1）城市与农村地区；（2）公寓楼与房屋；（3）被认为不安全与安全的邻里；（4）低收入与高收入家庭；以及（5）拉丁裔、非裔美国人、亚裔或白人青少年。分析还研究了公园可及性与这些因素之间的相互作用。
对于城市地区而非农村地区的青少年，安全公园的可及性与定期体育活动呈正相关，与不活动呈负相关。此外，在居住于（1）公寓楼、（2）不安全邻里和（3）低收入家庭中的青少年中，有安全公园可及性的青少年比没有的青少年更不易不活动。公园可及性与这些群体的定期体育活动无关。公园可及性与体育活动之间的关联因种族/族裔而异。
这些发现表明，体育活动与公园可及性之间的关系因青少年的社会人口统计学特征、住房情况及邻里特征而异，并且公园对于促进城市青少年的体育活动可能特别重要。
