The objective of this study was to determine whether places of consumption are associated with types of eating occasions. Data on dietary behaviors of 226 adults in five U.S. cities were collected in food diaries for one week. Types of eating occasions and places of consumption were recorded. Eating occasions were defined as occurrences of meal, snack, beverage, and non-fruit dessert consumption. Nearly one-third of eating occasions occurred at non-designated eating places. Repeated measure generalized linear models were used to assess the associations between types of eating occasions and places where food was consumed. Snacking on low-nutrient foods were more likely to occur in non-designated eating places. Snacking was more likely at work than at home, and sugar sweetened beverage consumption was more likely at food service outlets than at home. The finding that places of consumption were associated with different types of eating occasions suggests that contextual characteristics of a place are important in individual eating behaviors. Policies and programs aiming to promote healthy eating should leverage contextual characteristics of eating environments.
本研究的目的是确定消费场所是否与饮食场合的类型相关。通过食物日记收集了美国五个城市226名成年人一周的饮食行为数据。记录了饮食场合的类型和消费场所。饮食场合被定义为用餐、吃零食、喝饮料和食用非水果甜点的情况。近三分之一的饮食场合发生在非指定的就餐场所。使用重复测量广义线性模型来评估饮食场合类型与食物消费场所之间的关联。在非指定就餐场所更有可能吃低营养的零食。在工作时吃零食的可能性比在家中更大,而在食品服务场所饮用含糖饮料的可能性比在家中更大。消费场所与不同类型的饮食场合相关这一发现表明,场所的背景特征对个人饮食行为很重要。旨在促进健康饮食的政策和计划应利用饮食环境的背景特征。
