This study examined the use of the household dietary diversity score (HDDS) to assess household nutrient adequacy in Ethiopia. It also examined the correlates of HDDS following the food systems framework. Results show that the average nutrient consumption in Ethiopia varies by place of residence and by income profile, where households in urban areas and those in the higher income quintiles rank favorably. Among 13 nutrients under study, we found nutrient inadequacy for fat, calcium, zinc, riboflavin, niacin, folate, vitamin C and vitamin A ranging between 46% and 89%, and the prevalence of inadequacy for vitamin B12 to be up to 100%. Econometric results showed that HDDS is a strong predictor of a household’s mean probability of nutrient adequacy (MPA), and that an HDDS of 10 is the minimum threshold at which HDDS can improve household MPA. We found suggestive evidence within the food systems that improving household-incomes, access to health and transport services are beneficial to improve HDDS and nutrient consumption in Ethiopia.

家庭饮食多样性能否告知营养充足情况？埃塞俄比亚粮食系统分析的经验教训

本研究检查了使用家庭膳食多样性评分 (HDDS) 来评估埃塞俄比亚家庭营养充足性的情况。它还按照食品系统框架检查了 HDDS 的相关性。结果表明，埃塞俄比亚的平均营养消耗因居住地和收入状况而异，其中城市地区的家庭和收入较高的五分之一的家庭排名靠前。在研究的 13 种营养素中，我们发现脂肪、钙、锌、核黄素、烟酸、叶酸、维生素 C 和维生素 A 的营养素不足率介于 46% 至 89% 之间，维生素 B12 不足的发生率高达 100% . 计量经济学结果表明，HDDS 是家庭营养充足率 (MPA) 平均概率的强预测因子，HDDS 为 10 是 HDDS 可以改善家庭 MPA 的最低阈值。
