In 2020, Mexico implemented innovative front-of-package nutrition warning labels (FoPWLs) for packaged foods to increase the salience and understanding of nutrition information. This study evaluated Mexican Americans' self-reported exposure to Mexican FoPWLs and self-reported effects of FoPWLs on purchasing behavior.
The 2021 International Food Policy Study surveyed online panels of adult Mexican Americans in the US (n = 3361) to self-report on buying food at Mexican-oriented stores, noticing Mexican FoPWLs, and being influenced by FoPWLs to purchase less of eight different unhealthy foods (each assessed separately). After recoding the frequency of buying foods in Mexican stores and noticing FoPWLs (i.e., "often" or "very often" vs. less often), logistic models regressed these outcomes on sociodemographics, adjusting for post-stratification weights.
Most participants (88.0%) purchased foods in Mexican stores. Of these, 64.1% reported noticing FoPWLs, among whom many reported that FoPWLs influenced them to buy fewer unhealthy foods (range = 32% [snacks like chips] - 44% [colas]). Participants were more likely to buy foods in Mexican stores and notice FoPWLs if they were younger, had ≥two children at home vs no children (AOR = 1.40, 95%CI = 1.15-1.71; AOR = 1.37, 95%CI = 1.03-1.80, respectively), and more frequently used Spanish (AOR = 1.91, 95%CI = 1.77-2.07; AOR = 1.87, 95%CI = 1.69-2.07). Also, high vs. low education (AOR = 1.51, 95%CI = 1.17-1.94) and higher income adequacy (AOR = 1.37, 95%CI = 1.25-1.51) were positively associated with noticing FoPWLs. Being female and more frequent Spanish use were consistently associated with reporting purchase of fewer unhealthy foods because of FoPWLs.
Many Mexican Americans report both exposure to Mexican FOPWLs and reducing purchases of unhealthy foods because of them.
2020 年，墨西哥为包装食品实施了具有创新性的包装正面营养警示标签（FoPWL），以提高营养信息的显著性和理解度。本研究评估了墨西哥裔美国人对墨西哥 FoPWL 的自我报告暴露情况以及 FoPWL 对购买行为的自我报告影响。
2021 年国际粮食政策研究在美墨西哥裔成年人在线群体中进行了调查（n=3361），以自我报告在面向墨西哥人的商店购买食物、注意到墨西哥 FoPWL 以及受到 FoPWL 影响而购买八种不同不健康食品（每种食品分别评估）的情况。在对在墨西哥商店购买食品和注意到 FoPWL 的频率进行重新编码（即“经常”或“非常经常”与不经常）后，使用逻辑回归模型，根据事后分层权重，调整这些结果的社会人口统计学因素。
大多数参与者（88.0%）在墨西哥商店购买食品。其中，64.1%报告注意到 FoPWL，其中许多人表示 FoPWL 影响他们购买较少的不健康食品（范围为 32%[如薯片等零食]至 44%[可乐]）。如果参与者年龄较小、家中有≥2 个孩子而不是没有孩子（AOR=1.40，95%CI=1.15-1.71；AOR=1.37，95%CI=1.03-1.80），并且更频繁地使用西班牙语（AOR=1.91，95%CI=1.77-2.07；AOR=1.87，95%CI=1.69-2.07），则他们更有可能在墨西哥商店购买食品并注意到 FoPWL。此外，与低教育程度相比，高教育程度（AOR=1.51，95%CI=1.17-1.94）和更高的收入充足度（AOR=1.37，95%CI=1.25-1.51）与注意到 FoPWL 呈正相关。女性和更频繁地使用西班牙语与报告因 FoPWL 而减少购买不健康食品的情况始终相关。
许多墨西哥裔美国人既报告了对墨西哥 FoPWL 的接触，也报告了因为 FoPWL 而减少购买不健康食品。
