Extensive research has shown that spending time in natural greenspaces has a positive impact on health. However, there is limited evidence regarding potential factors that may influence these effects. This review aimed to assess the strength of the evidence and potential impact of exposure to green and bluespaces on dietary outcomes in adults. Inclusion criteria for the review were based on the PICO criteria. Following PRISMA guidelines, an initial search of five databases was conducted: CINAHL, GreenFILE, AMED, Medline, and PubMed, accessed on 14th June 2021 and augmented by an updated rerun in January 2024. All studies used the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Analytical Cross-Sectional Studies for quality assessment. Due to heterogeneity, a narrative synthesis was conducted to evaluate the relationships between the included studies. Four observational studies that reported diet-related outcomes were included in the review, and participants within the studies ranged from 554 to >350,000 participants. Other health outcomes, including physical activity and obesity, were also reported. Two studies found that dietary patterns were not correlated with exposure to greenspace. Due to the small number of articles retrieved and the paucity of evidence, the findings must be interpreted cautiously. In conclusion, further research is essential to clarify the intricate mechanisms involved in greenspace-related health benefits. Additionally, investigating the specific greenspace attributes influencing adult dietary intake and food choices is warranted. When devising public health interventions, it is crucial to account for the substantial health advantages associated with various socioeconomic groups.
广泛的研究表明，置身于自然绿地对健康有积极影响。然而，关于可能影响这些效果的潜在因素的证据有限。本综述旨在评估接触绿色和蓝色空间对成年人饮食结果的证据强度和潜在影响。该综述的纳入标准基于PICO标准。按照PRISMA指南，对五个数据库进行了初步检索：CINAHL、GreenFILE、AMED、Medline和PubMed，于2021年6月14日进行访问，并在2024年1月进行了更新检索。所有研究均使用乔安娜·布里格斯研究所（JBI）分析性横断面研究的批判性评估清单进行质量评估。由于存在异质性，进行了叙述性综合分析以评估纳入研究之间的关系。该综述纳入了四项报告饮食相关结果的观察性研究，研究中的参与者人数从554人到超过35万人不等。还报告了包括身体活动和肥胖在内的其他健康结果。两项研究发现饮食模式与接触绿地无关。由于检索到的文章数量较少且证据不足，这些发现必须谨慎解读。总之，进一步的研究对于阐明与绿地相关的健康益处所涉及的复杂机制至关重要。此外，有必要调查影响成年人饮食摄入量和食物选择的特定绿地属性。在制定公共卫生干预措施时，考虑与不同社会经济群体相关的重大健康益处至关重要。
