Researchers are increasingly interested in understanding how food environments influence eating behavior and weight-related health outcomes. Little is known about the dose-response relationship between foodscapes and behavior or weight, with measures of food exposure having mainly focused on fixed anchor points including residential neighborhoods, schools, or workplaces. Recent calls have been made to extend the consideration of environmental influences beyond local neighborhoods and also to shift away from place-based, to people-based, measures of exposure. This report presents analyses of novel activity-space measures of exposure to foodscapes, combining travel survey data with food store locations in Montreal and Quebec City, Canada. The resulting individual activity-space experienced foodscape exposure measures differ from traditional residential-based measures, and show variations by age and income levels. Furthermore, these activity-space exposure measures once modeled, can be used as predictors of health outcomes. Hence, travel surveys can be used to estimate environmental exposure for health survey participants.
研究人员越来越关注了解食物环境如何影响饮食行为和与体重相关的健康结果。对于食物景观与行为或体重之间的剂量反应关系知之甚少,食物暴露的衡量标准主要集中在固定的锚点上,包括居住社区、学校或工作场所。最近有人呼吁将环境影响的考虑范围扩大到当地社区之外,并从基于地点的措施转向基于人的暴露措施。本报告介绍了对食物景观暴露的新型活动空间衡量标准的分析,该分析结合了旅行调查数据和加拿大蒙特利尔和魁北克市的食品店位置。由此产生的个体活动空间所经历的食物景观暴露衡量标准与传统的基于居住地的衡量标准不同,并且按年龄和收入水平有所不同。此外,一旦对这些活动空间暴露措施进行建模,就可以将其用作健康结果的预测指标。因此,旅行调查可用于估计健康调查参与者的环境暴露情况。
