缺乏体育活动和过度消费高能量食物与超重和肥胖有关。邻里环境可能促进或阻碍健康生活方式的发展和/或维持。为了提高对邻里环境致肥胖性的研究，需要可靠、有效、方便的邻里环境潜在致肥胖特征的评估方法。本研究探讨SPOTLIGHT虚拟审计工具（S-VAT）的可靠性和有效性，它使用遥感技术（街景功能在谷歌地球）为基础的桌面环境致肥胖性评估。共128个街道段在四个荷兰城市街区-异质的社会经济地位和住宅密度-进行了评估，使用S-VAT。环境特征被分类为步行相关项目，骑自行车相关项目，公共交通，美学，土地使用组合，杂货店，食品店和体育活动设施。为了评估Google Earth中街景功能的观察者间和观察者内可靠性的一致性，以及与真实的生活审计的有效性评分，计算一致性百分比和Cohen's Kappa（k）。观察者内可靠性较高，范围为91.7%一致率（k = 0.654）至100%一致率（k = 1.000），总体一致率为96.4%（k = 0.848）。观察者间可靠性结果的范围从基本一致性78.6%（k = 0.440）到高度一致性99.2%（k = 0.579），总体一致性为91.5%（k = 0.595）。对于大多数类别，标准有效性为实质性至高，范围为87.3%一致率（k = 0.539）至99.9%一致率（k = 0.887），总体评分为95.6%一致率（k = 0.747）。这些研究结果表明，S-VAT是一个高度可靠和有效的遥感工具，以评估潜在的致肥胖的环境特征。本文的在线版本（doi：10.1186/1476 - 072X-13 - 52）包含补充材料，可供授权用户使用。
A lack of physical activity and overconsumption of energy dense food is associated with overweight and obesity. The neighbourhood environment may stimulate or hinder the development and/or maintenance of a healthy lifestyle. To improve research on the obesogenicity of neighbourhood environments, reliable, valid and convenient assessment methods of potential obesogenic characteristics of neighbourhood environments are needed. This study examines the reliability and validity of the SPOTLIGHT-Virtual Audit Tool (S-VAT), which uses remote sensing techniques (Street View feature in Google Earth) for desk-based assessment of environmental obesogenicity. A total of 128 street segments in four Dutch urban neighbourhoods – heterogeneous in socio-economic status and residential density – were assessed using the S-VAT. Environmental characteristics were categorised as walking related items, cycling related items, public transport, aesthetics, land use-mix, grocery stores, food outlets and physical activity facilities. To assess concordance of inter- and intra-observer reliability of the Street View feature in Google Earth, and validity scores with real life audits, percentage agreement and Cohen's Kappa (k) were calculated. Intra-observer reliability was high and ranged from 91.7% agreement (k = 0.654) to 100% agreement (k = 1.000) with an overall agreement of 96.4% (k = 0.848). Inter-observer reliability results ranged from substantial agreement 78.6% (k = 0.440) to high agreement, 99.2% (k = 0.579), with an overall agreement of 91.5% (k = 0.595). Criterion validity was substantial to high for most of the categories ranging from 87.3% agreement (k = 0.539) to 99.9% agreement (k = 0.887) with an overall score of 95.6% agreement (k = 0.747). These study results suggest that the S-VAT is a highly reliable and valid remote sensing tool to assess potential obesogenic environmental characteristics.
