Obesogenic environments promote excessive caloric and fat intake. A total of 23 low-income, African American adolescents digitally photographed their lunchtime food environment at a school buffet during summer camp. Depicted food was coded for nutritional content on the platescape (own plate or others’ plates) and the tablescape (open buffet). Students digitally depicted high-caloric and high-fat content, particularly students who had higher baseline waist-to-hip ratio. Students who included higher caloric and fat content in their digital diaries gained more weight over the 4-week program than those who did not. Digital photography connects adolescents’ perceived food environment with weight gain, revealing the environmental cues that promote excessive caloric and fat intake. Digital photography can also identify adolescents with problematic eating behaviors that increase risk for obesity.

 饮食数字日记


致肥胖的环境会促进热量和脂肪的过量摄入。夏令营期间，共有 23 名低收入非裔美国青少年在学校自助餐厅用数码照片拍摄了他们午餐时的食物环境。所描绘的食物在餐盘（自己的餐盘或其他人的餐盘）和餐桌（开放式自助餐）上根据营养成分进行编码。学生以数字方式描绘高热量和高脂肪内容，尤其是腰臀比基线较高的学生。在为期 4 周的计划中，在数字日记中包含较高热量和脂肪含量的学生比没有添加热量和脂肪含量的学生增加了更多体重。数码摄影将青少年感知的食物环境与体重增加联系起来，揭示了促进热量和脂肪摄入过多的环境线索。数码摄影还可以识别有问题饮食行为的青少年，这些行为会增加肥胖风险。
