Increasing numbers of epidemiological studies are investigating the association between outdoor greenery and various health outcomes. However, in the case of indoor plants, although experimental studies seem relatively abundant, epidemiological studies remain scarce, and research considering the mental health effects is even more limited. Thus, we aim to identify and summarise the relevant epidemiological studies on indoor plant exposure and mental health via this scoping review, thereby presenting the current state of knowledge and research niches.
PubMed and PsycINFO were systematically searched for epidemiological studies on indoor plant exposure and mental health, including mental and behavioural disorders, quality of life, and cognitive function. The publication period was from the inception of these two databases to 22nd June 2022. We extracted information on exposure to indoor plants and mental health-related outcomes from the relevant studies.
The systematic search yielded 1186 unique results. Six studies met the inclusion criteria and were finally included in this scoping review. All included studies were Europe-based cross-sectional studies on mental and behavioural disorders. One study was conducted in 2015 and investigated the office environment, whereas the other five were conducted during the COVID-19 pandemic and focused on the home environment. Despite considerable heterogeneity in outcome assessments and indoor plant exposure metrics, all six studies generally reported beneficial associations between having indoor plants and mental health, such as reducing stress, depressive symptoms, and negative emotions.
Epidemiological evidence on exposure to indoor plants and mental health is currently limited. In general, favourable effects of indoor plants are supported, although most relevant studies were conducted in the context of COVID-19. Before conducting more studies to explore the associations, data collection methods must be refined with more elaborate designs that allow for the measurement of more comprehensive metrics of indoor plants.

越来越多的流行病学研究调查了户外绿化与各种健康结果之间的关系。然而，就室内植物而言，尽管实验研究似乎相对丰富，但流行病学研究仍然很少，考虑心理健康影响的研究更是有限。因此，我们旨在通过这篇范围综述来确定和总结有关室内植物暴露与心理健康的相关流行病学研究，从而呈现当前的知识状态和研究重点。
系统地检索了 PubMed 和 PsycINFO 中有关室内植物暴露与心理健康的流行病学研究，包括精神和行为障碍、生活质量和认知功能。检索的时间范围为这两个数据库建立之初至 2022 年 6 月 22 日。我们从相关研究中提取了有关室内植物暴露与心理健康相关结果的信息。
系统检索产生了 1186 条独特的结果。有 6 项研究符合纳入标准，最终被纳入本范围综述。所有纳入的研究都是基于欧洲的关于精神和行为障碍的横断面研究。其中一项研究于 2015 年进行，调查了办公环境，而其他五项研究则在 COVID-19 大流行期间进行，重点关注家庭环境。尽管在结果评估和室内植物暴露指标方面存在很大的异质性，但所有六项研究通常都报告了室内植物与心理健康之间存在有益的关联，例如减轻压力、抑郁症状和负面情绪。
目前有关室内植物暴露与心理健康的流行病学证据有限。一般来说，室内植物的有利影响得到了支持，尽管大多数相关研究都是在 COVID-19 背景下进行的。在进行更多研究来探索关联之前，必须改进数据收集方法，采用更精细的设计，以便更全面地测量室内植物的各项指标。
