Recent evidence supports the hypothesis that aflatoxin exposure from maize can influence malnutrition rates among children. Therefore, in Guatemala we investigated two questions; which maize sources exposed households to higher risk of aflatoxin exposure symptoms and what the risk factors were for each maize source, pre- and post-maize harvest. Survey data and household maize samples were collected in October 2016 (pre-harvest) and February 2017 (post-harvest) in San Vicente, Guatemala. Structural equation modeling (SEM) and odds ratios were used to assess the data. The results suggested that households which purchased maize from the market had 3.64 higher odds of high levels of aflatoxin. The models identified that good market purchase habits were significant for market-based maize sources while improved post-harvest practices and improved types of maize storage were significant for subsistence-based maize sources. Cumulative results suggest multiple interventions may be effective but are dependent on time of year and source of maize.
近期证据支持这样一种假说，即玉米中的黄曲霉毒素暴露会影响儿童的营养不良率。因此，在危地马拉，我们调查了两个问题：哪些玉米来源使家庭面临更高的黄曲霉毒素暴露症状风险，以及每种玉米来源在玉米收获前和收获后的风险因素是什么。2016年10月（收获前）和2017年2月（收获后）在危地马拉的圣维森特收集了调查数据和家庭玉米样本。使用结构方程模型（SEM）和优势比来评估数据。结果表明，从市场购买玉米的家庭黄曲霉毒素含量高的几率高出3.64倍。模型确定，良好的市场购买习惯对基于市场的玉米来源很重要，而改进的收获后做法和改进的玉米储存类型对基于自给自足的玉米来源很重要。累积结果表明，多种干预措施可能有效，但取决于一年中的时间和玉米来源。
