Increasing rates of childhood obesity worldwide has focused attention on the obesogenic food environment. This paper reports an analysis of children's interactions with food in convenience stores. Kids'Cam was a cross-sectional study conducted from July 2014 to June 2015 in New Zealand in which 168 randomly selected children aged 11-14 years old wore a wearable camera for a 4-day period. In this ancillary study, images from children who visited a convenience store were manually coded for food and drink availability. Twenty-two percent of children ( = 37) visited convenience stores on 62 occasions during the 4-day data collection period. Noncore items dominated the food and drinks available to children at a rate of 8.3 to 1 (means were 300 noncore and 36 core, respectively). The food and drinks marketed in-store were overwhelmingly noncore and promoted using accessible placement, price offers, product packaging, and signage. Most of the 70 items purchased by children were noncore foods or drinks (94.6%), and all of the purchased food or drink subsequently consumed was noncore. This research highlights convenience stores as a key source of unhealthy food and drink for children, and policies are needed to reduce the role of convenience stores in the obesogenic food environment.
全球儿童肥胖率不断上升，促使人们关注肥胖相关的食物环境。本文报告了一项关于儿童在便利店与食物互动的分析。Kids'Cam 是一项在新西兰进行的横断面研究，于 2014 年 7 月至 2015 年 6 月期间，随机选择了 168 名年龄在 11-14 岁的儿童佩戴可穿戴摄像机进行为期 4 天的拍摄。在这项辅助研究中，对孩子们在便利店的图像进行手动编码，以获取食物和饮料的供应情况。在 4 天的数据收集期间，有 22%的孩子（37 人）在 62 次访问便利店。非核心项目占据了便利店提供给儿童的食物和饮料的主导地位，比例为 8.3 比 1（平均值分别为 300 份非核心项目和 36 份核心项目）。店内销售的食品和饮料绝大多数是非核心项目，通过易接近的位置、价格优惠、产品包装和标识进行推广。孩子们购买的 70 种商品中，有 94.6%是非核心食品或饮料，随后消费的所有食物或饮料均为非核心项目。这项研究强调了便利店是儿童获取不健康食品和饮料的主要来源，需要制定政策来减少便利店在肥胖相关食物环境中的作用。
