In this study, we explore how to use household expenditures and income surveys (HEIS) to provide replicable and comparable measures of nutrients availability at the population level. Our method formalizes the common practice in the literature and consists of three steps: identification of relevant food categories, pairing of food contents food groups in HEIS data, and calculation of the typical amount of nutrients by food group. We illustrate the usage of the method with Mexican data and provide a publicly available data set to readily convert food purchases into six nutrients: calories, proteins, vitamins A and C, iron, and zinc. We perform a descriptive analysis of the evolution of nutrients intake among Mexican households between 2008 and 2020, considering differences by income level. Our results reflect the effect of the COVID-19 pandemic on nutrient availability in Mexican households, mainly driven by a substantial reduction in the expenditure in food consumed away from home, although for most nutrients the trend was stable over most of the period.
在本研究中，我们探讨了如何利用家庭支出和收入调查（HEIS）来提供可重复和可比的人群水平营养物质可得性衡量标准。我们的方法形式化了文献中的常见做法，包括三个步骤：确定相关食品类别、将 HEIS 数据中的食品内容与食物组配对，以及计算每个食物组的典型营养物质含量。我们使用墨西哥数据来说明该方法的使用，并提供了一个公开可用的数据集，可将食品购买量转换为六种营养物质：卡路里、蛋白质、维生素 A 和 C、铁和锌。我们考虑了不同收入水平的差异，对 2008 年至 2020 年期间墨西哥家庭营养物质摄入量的演变进行了描述性分析。我们的结果反映了 COVID-19 大流行对墨西哥家庭营养物质可得性的影响，主要是由于外出就餐的食品支出大幅减少，但对于大多数营养物质来说，在大部分时间内趋势是稳定的。
