Scientific research has widely examined the therapeutic and health benefits of being in contact with natural environments. Nature walk have been proposed as a cost-effective and inclusive method for successfully exploiting nature for the promotion of health and well-being. Depression and anxiety symptoms have been shown to benefit from nature walk. Despite recent empirical findings published in the scientific literature, a summary quantitative work on the effect of nature walk on depression and anxiety does not yet exist. The present systematic review and meta-analysis quantitatively analyze and qualitatively discuss the studies published on the effect of nature walk on depression and anxiety published during the past decade. A database search as well as snowballing methods were used to retrieve eligible articles. The research question and literature search were based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Based on screening and retrieval processes, seven studies met the eligibility criteria and were then included in the quantitative meta-analysis. Risk of bias (RoB) analysis was used to evaluate the quality of the included studies using the Newcastle-Ottawa Scale. After a qualitative evaluation of the studies, data from six experiments were included in the meta-analysis. The meta-analysis show that nature walk effectively improve mental health. The findings were confirmed for the experiments reporting the quantitative data within groups (pre- and post-test) and between groups (experimental vs. control group).
科学研究广泛探讨了接触自然环境的治疗作用和健康益处。自然漫步已被视为一种经济高效且具有包容性的方法，能够成功利用自然来促进健康和福祉。研究表明，自然漫步对抑郁和焦虑症状有益。尽管科学文献中已有近期的实证研究结果，但尚未有关于自然漫步对抑郁和焦虑影响的汇总定量研究。本系统综述和荟萃分析对过去十年间发表的有关自然漫步对抑郁和焦虑影响的研究进行了定量分析和定性讨论。通过数据库检索以及滚雪球法来检索符合条件的文章。研究问题和文献检索基于系统评价和荟萃分析的首选报告项目（PRISMA）声明。基于筛选和检索过程，七项研究符合纳入标准，随后被纳入定量荟萃分析。采用偏倚风险（RoB）分析，使用纽卡斯尔-渥太华量表评估纳入研究的质量。在对这些研究进行定性评估后，六项实验的数据被纳入荟萃分析。荟萃分析表明，自然漫步能有效改善心理健康。对于报告组内（前后测）和组间（实验组与对照组）定量数据的实验，这一结果得到了证实。
