We examine the link between maternal nutrition knowledge and nutritional outcomes of children and adolescents (5-18 years) measured in terms of height-for-age Z-scores (HAZ). One particular focus is on the role of different types of nutrition knowledge. The analysis builds on household-level and individual-level data collected in urban Kenya in 2012 and 2015. Various regression models are developed and estimated. Results show that maternal nutrition knowledge - measured through an aggregate knowledge score - is positively associated with child HAZ, even after controlling for other influencing factors such as household living standard and general maternal education. However, disaggregation by type of knowledge reveals important differences. Maternal knowledge about food ingredients only has a weak positive association with child HAZ. For maternal knowledge about specific dietary recommendations, no significant association is detected. The strongest positive association with child HAZ is found for maternal knowledge about the health consequences of not following recommended dietary practices. These findings have direct relevance for nutrition and health policies, especially for designing the contents of educational campaigns and training programs.
我们研究了母亲营养知识与儿童和青少年（5-18 岁）身高年龄 Z 分数（HAZ）等营养结果之间的联系。特别关注的是不同类型的营养知识的作用。该分析基于 2012 年和 2015 年在肯尼亚城市收集的家庭层面和个人层面的数据。开发并估计了各种回归模型。结果表明，即使在控制了其他影响因素（如家庭生活水平和一般母亲教育）之后，通过综合知识得分衡量的母亲营养知识与儿童 HAZ 呈正相关。然而，按知识类型进行细分揭示了重要的差异。母亲对食物成分的知识仅与儿童 HAZ 呈微弱正相关。对于母亲对特定饮食建议的知识，未发现显著关联。与儿童 HAZ 呈最强正相关的是母亲对不遵循推荐饮食实践的健康后果的知识。这些发现对营养和健康政策具有直接意义，特别是在设计教育活动和培训计划的内容方面。
