调查使用可穿戴摄像头作为一种方法来捕捉年轻人在往返学校的常规旅程中遇到的食品和饮料购买/消费机会的可行性和可接受性。一项定性研究使用多种数据收集方法，包括可穿戴相机，全球定位系统单元，个人访谈，参与者在四天内完成的食品和饮料购买和消费日记，以及对位于每所学校周围800米欧几里得缓冲区内的食品店的审计。一个社区设置。从英格兰两个县的四所中学招募了22名13-15岁的学生（14名女孩和8名男孩）。可穿戴摄像头提供了一种可行且可接受的方法，用于收集少数青少年的食物购买和消费数据，同时使用传统的数据收集方法。我们发现有证据表明，参与者在旅途中故意选择是否购买/消费食物和饮料。这些选择受到金钱、朋友、旅程长度、旅行模式和容易获得购买/消费机会的优先事项的影响。大多数食物和饮料都是在学校周围800米的欧几里得缓冲区内购买/消费的，通常选择的食物是高能量，高脂肪和高糖的。可穿戴相机图像与采访相结合，有助于识别未报告的项目和误报错误。可穿戴摄像头的图像可以引发详细的讨论，并生成特定的上下文信息，这些信息可以提供关于饮食行为模式的新见解和理解。扩大使用这些方法的可行性需要进一步的实证工作。
To investigate the feasibility and acceptability of using wearable cameras as a method to capture the opportunities for food and drink purchasing/consumption that young people encounter on their regular journeys to and from school. A qualitative study using multiple data-collection methods including wearable cameras, global positioning system units, individual interviews, food and drink purchase and consumption diaries completed by participants over four days, and an audit of food outlets located within an 800 m Euclidean buffer zone around each school. A community setting. Twenty-two students (fourteen girls and eight boys) aged 13–15 years recruited from four secondary schools in two counties of England. Wearable cameras offered a feasible and acceptable method for collecting food purchase and consumption data when used alongside traditional methods of data collection in a small number of teenagers. We found evidence of participants making deliberate choices about whether or not to purchase/consume food and drink on their journeys. These choices were influenced by priorities over money, friends, journey length, travel mode and ease of access to opportunities for purchase/consumption. Most food and drink items were purchased/consumed within an 800 m Euclidean buffer around school, with items commonly selected being high in energy, fat and sugar. Wearable camera images combined with interviews helped identify unreported items and misreporting errors. Wearable camera images prompt detailed discussion and generate contextually specific information which could offer new insights and understanding around eating behaviour patterns. The feasibility of scaling up the use of these methods requires further empirical work.
