OBJECTIVES
To compare changes in food-purchasing knowledge, self-efficacy, and behavior after viewing nutrition education videos among Los Angeles, California Latinas responsible for household grocery shopping.
METHODS
From February to May 2015, a convenience sample of 113 Latinas watched 1 video (El Carrito Saludable) featuring MyPlate guidelines applied to grocery shopping (1-video intervention) and another convenience sample of 105 Latinas watched 2 videos (El Carrito Saludable and Ser Consciente), the latter featuring mindfulness to support attention and overcome distractions while grocery shopping (2-video intervention). We administered questionnaires before and after intervention. A preselected sample in each intervention condition (n = 72) completed questionnaires at 2-months after intervention and provided grocery receipts (before and 2-months after intervention).
RESULTS
Knowledge improved in both intervention groups (P < .001). The 2-video group improved more in self-efficacy and use of a shopping list (both P < .05) and purchased more healthy foods (d = 0.60; P < .05) at 2 months than did the 1-video group.
CONCLUSIONS
Culturally tailored videos that model food-purchasing behavior and mindfulness show promise for improving the quality of foods that Latinas bring into the home.
目的
比较观看营养教育视频后，负责家庭食品采购的加利福尼亚州洛杉矶拉丁裔女性在食品采购知识、自我效能感和行为方面的变化。
方法
2015年2月至5月，113名拉丁裔女性的便利样本观看了1个视频（《健康购物车》），该视频展示了应用于食品采购的“我的餐盘”指南（单视频干预）；另一个由105名拉丁裔女性组成的便利样本观看了2个视频（《健康购物车》和《保持清醒》），后者展示了在食品采购时保持正念以集中注意力并克服干扰（双视频干预）。我们在干预前后进行了问卷调查。每个干预组中预先选定的样本（n = 72）在干预后2个月完成问卷调查，并提供食品采购收据（干预前和干预后2个月）。
结果
两个干预组的知识水平均有所提高（P < 0.001）。双视频组在自我效能感和使用购物清单方面的改善更为明显（P均< 0.05），并且在2个月时比单视频组购买了更多健康食品（d = 0.60；P < 0.05）。
结论
对文化进行了针对性调整、展示食品采购行为和正念的视频有望提高拉丁裔女性带回家的食品质量。
