The authors designed an instrument to measure objectively aspects of the built and food environments in urban areas, the EURO-PREVOB Community Questionnaire, within the EU-funded project 'Tackling the social and economic determinants of nutrition and physical activity for the prevention of obesity across Europe' (EURO-PREVOB). This paper describes its development, reliability, validity, feasibility and relevance to public health and obesity research.
The Community Questionnaire is designed to measure key aspects of the food and built environments in urban areas of varying levels of affluence or deprivation, within different countries. The questionnaire assesses (1) the food environment and (2) the built environment.
Pilot tests of the EURO-PREVOB Community Questionnaire were conducted in five to 10 purposively sampled urban areas of different socio-economic status in each of Ankara, Brno, Marseille, Riga, and Sarajevo. Inter-rater reliability was compared between two pairs of fieldworkers in each city centre using three methods: inter-observer agreement (IOA), kappa statistics, and intraclass correlation coefficients (ICCs).
Data were collected successfully in all five cities. Overall reliability of the EURO-PREVOB Community Questionnaire was excellent (inter-observer agreement (IOA) > 0.87; intraclass correlation coefficients (ICC)s > 0.91 and kappa statistics > 0.7. However, assessment of certain aspects of the quality of the built environment yielded slightly lower IOA coefficients than the quantitative aspects.
The EURO-PREVOB Community Questionnaire was found to be a reliable and practical observational tool for measuring differences in community-level data on environmental factors that can impact on dietary intake and physical activity. The next step is to evaluate its predictive power by collecting behavioural and anthropometric data relevant to obesity and its determinants.
作者设计了一种工具来客观测量城市地区的建筑和食品环境方面，即欧盟资助的项目“解决欧洲营养和身体活动的社会和经济决定因素以预防肥胖”（EURO-PREVOB）中的 EURO-PREVOB 社区问卷。本文描述了其开发、可靠性、有效性、可行性以及与公共卫生和肥胖研究的相关性。
社区问卷旨在衡量不同富裕程度或贫困程度的不同国家城市地区的食品和建筑环境的关键方面。问卷评估（1）食品环境和（2）建筑环境。
在安卡拉、布尔诺、马赛、里加和萨拉热窝的每个城市中心，对 EURO-PREVOB 社区问卷进行了五到十次有针对性抽样的城市地区的试点测试。使用三种方法比较每个城市中心的两名实地工作者之间的评分者间可靠性：观察者间一致性（IOA）、kappa 统计和组内相关系数（ICC）。
所有五个城市都成功收集了数据。EURO-PREVOB 社区问卷的整体可靠性非常好（观察者间一致性（IOA）>0.87；组内相关系数（ICC）>0.91 和 kappa 统计>0.7。然而，对建筑环境质量某些方面的评估得出的 IOA 系数略低于定量方面。
EURO-PREVOB 社区问卷是一种可靠且实用的观察工具，可用于测量可能影响饮食摄入和身体活动的环境因素的社区水平数据差异。下一步是通过收集与肥胖及其决定因素相关的行为和人体测量数据来评估其预测能力。
