Close economic ties encourage production and trade of meat between Canada, Mexico, and the US. Understanding the patterns of red and processed meat consumption in North America may inform policies designed to reduce meat consumption and bolster environmental and public health efforts across the continent. We used nationally-representative cross-sectional survey data to analyze consumption of unprocessed red meat; processed meat; and total red and processed meat. Generalized linear models were used to separately estimate probability of consumption and adjusted mean intake. Prevalence of total meat consumers was higher in the US (73.6, 95% CI: 72.3-74.8%) than in Canada (65.6, 63.9-67.2%) or Mexico (62.7, 58.1-67.2%). Men were more likely to consume unprocessed red, processed, and total meat, and had larger estimated intakes. In Mexico, high wealth individuals were more likely to consume all three categories of meat. In the US and Canada, those with high education were less likely to consume total and processed meat. Estimated mean intake of unprocessed red, processed, and total meat did not differ across sociodemographic strata. Overall consumption of red and processed meat remains high in North America. Policies to reduce meat consumption are appropriate for all three countries.
紧密的经济联系促进了加拿大、墨西哥和美国之间的肉类生产和贸易。了解北美地区红肉类和加工肉类消费模式可以为旨在减少肉类消费、加强整个地区环境和公共卫生工作的政策提供信息。我们使用全国代表性的横断面调查数据来分析未加工的红肉类、加工肉类以及总红肉类和加工肉类的消费情况。使用广义线性模型分别估计消费的可能性和调整后的平均摄入量。总肉类消费者的患病率在美国(73.6%,95%置信区间:72.3%-74.8%)高于加拿大(65.6%,63.9%-67.2%)或墨西哥(62.7%,58.1%-67.2%)。男性更有可能消费未加工的红肉类、加工肉类和总肉类,且估计摄入量更大。在墨西哥,高财富人群更有可能消费所有三种肉类。在美国和加拿大,受教育程度较高的人消费总肉类和加工肉类的可能性较小。未加工的红肉类、加工肉类和总肉类的估计平均摄入量在社会人口统计学阶层之间没有差异。总体而言,北美地区的红肉类和加工肉类消费仍然很高。减少肉类消费的政策适用于所有三个国家。
