从理论上讲，P>；Greenspace是一种宝贵的体育活动资源，因此有潜力为减少肥胖和改善健康做出贡献。本文报告了一项系统的定量研究综述，考察了客观测量的获得绿地与(I)体力活动、(Ii)体重状况和(Iii)与超重相关的健康状况之间的关系。文献检索在Scope us、Medline、Embase和PYSCHINFO上进行。60项研究符合纳入标准，并对证据的方法学质量和强度进行了评估。大多数(68%)的论文发现绿地与肥胖相关的健康指标之间存在积极或微弱的联系，但研究结果并不一致，而且喜忧参半。几项研究发现，这种关系因年龄、社会经济地位和绿地衡量标准等因素而异。制定一个考虑不同类型绿地与健康之间的相互关系和相互作用的理论框架，将有助于研究设计和解释已报告的调查结果，以及改进绿地准入措施的质量和一致性。未来研究的关键领域包括调查人们是否以及如何实际使用绿地，以及增进对绿地改善健康的机制的理解，特别是身体活动是否是这样一种机制。
P>Greenspace is theoretically a valuable resource for physical activity and hence has potential to contribute to reducing obesity and improving health. This paper reports on a systematic review of quantitative research examining the association between objectively measured access to greenspace and (i) Physical activity, (ii) Weight status and (iii) Health conditions related to elevated weight. Literature searches were conducted in SCOPUS, Medline, Embase and PYSCHINFO. Sixty studies met the inclusion criteria and were assessed for methodological quality and strength of the evidence. The majority (68%) of papers found a positive or weak association between greenspace and obesity-related health indicators, but findings were inconsistent and mixed across studies. Several studies found the relationship varied by factors such as age, socioeconomic status and greenspace measure. Developing a theoretical framework which considers the correlates and interactions between different types of greenspace and health would help study design and interpretation of reported findings, as would improvement in quality and consistency of greenspace access measures. Key areas for future research include investigating if and how people actually use greenspace and improving understanding of the mechanisms through which greenspace can improve health and, in particular, if physical activity is one such mechanism.
