Crime and safety are often cited as potential hurdles to park use and park-based physical activity. Using comprehensive data sources including both objective and subjective measurements at the park level and the individual level, this study aimed to assess the association between crime rates and use of local parks in low-income urban neighborhoods.
The authors observed 48 parks and conducted local resident surveys in low-income neighborhoods in Los Angeles during a 2-year study period (2013-2015). Crime data were geocoded within a 1-mile radius of parks' addresses and longitudinal models were fitted to estimate the association between crime rates and park use outcomes in 2017.
One gun-related violent crime per 10,000 people during the 6-month period prior to data collection was associated with an average of 13.5%-15.8% reduction in observed park use and park-based moderate to vigorous physical activity (p<0.05) in the 6-month observation period. The relationship was significant in seniors (33%-40% reduction) and adults (13%-18%), but insignificant for teenagers (2%-4%) and children (10%-12%). Homicide rates were also significantly related to lower self-reported park use (p<0.05).
Gun-related violent crimes have relatively long-term negative associations with population health by reducing utilization of outdoor park space. There can be additional population health benefits from controlling and reducing gun-related violent crimes beyond immediate impacts on public safety and mortality.
犯罪和安全问题常被认为是人们使用公园和进行公园内身体活动的潜在障碍。本研究使用综合数据源,包括公园层面和个体层面的客观和主观测量数据,旨在评估犯罪率与低收入城市社区中人们使用当地公园之间的关系。
作者在 2013-2015 年为期 2 年的研究期间,观察了洛杉矶低收入社区的 48 个公园并进行了当地居民调查。将犯罪数据在公园地址 1 英里半径范围内进行地理编码,并拟合纵向模型以估计 2017 年犯罪率与公园使用结果之间的关系。
在数据收集前 6 个月,每 10000 人发生 1 起与枪支有关的暴力犯罪,与观察到的公园使用量和基于公园的中等到剧烈身体活动减少 13.5%-15.8%有关(p<0.05)。在 6 个月的观察期内,老年人(减少 33%-40%)和成年人(减少 13%-18%)的相关性显著,但青少年(减少 2%-4%)和儿童(减少 10%-12%)的相关性不显著。凶杀率也与自我报告的公园使用量减少显著相关(p<0.05)。
与枪支有关的暴力犯罪通过减少对户外公园空间的利用,对人口健康产生了相对长期的负面影响。除了对公共安全和死亡率的直接影响外,控制和减少与枪支有关的暴力犯罪还可能带来额外的人口健康益处。
