Abstract：
Dietary diversity among children is a crucial factor influencing their nutritional status; therefore, this paper uses data from four rounds of the Cambodia Demographic and Health Survey (CDHS) to examine the minimum dietary diversity among children aged 6-23 months. Multilevel binary regression is used to evaluate the variation in minimum dietary diversity at the cluster and province levels. The results show that nearly half of Cambodian children consistently lacked access to vitamin A-rich fruits and vegetables. Although the prevalence of inadequate minimum dietary diversity (MDD) among children significantly dropped from 76% in 2005 to 51% in 2021-2022, it is still high and needs attention. A decomposition analysis (Blinder-Oaxaca decomposition) was further used to understand the drivers of this temporal change in dietary diversity. The empirical results show that clusters represented the most significant source of geographic variation with respect to all eight food groups and MDD. Nutritional policy should improve education and awareness, reduce socio-economic disparities, leverage media, and promote full antenatal care to improve dietary diversity in Cambodia. Initiatives targeting the enhancement of insufficient minimum dietary diversity intake should encompass individual aspects and be customized to suit geographic and community settings.
摘要：
儿童的饮食多样性是影响其营养状况的关键因素；因此，本文使用四轮柬埔寨人口与健康调查（CDHS）的数据来检查6-23个月儿童的最低饮食多样性。多级二元回归用于评估集群和省一级的最小饮食多样性的变化。结果显示，近一半的柬埔寨儿童始终无法获得富含维生素A的水果和蔬菜。尽管儿童最低膳食多样性（MDD）不足的患病率从2005年的76％显着下降到2021-2022年的51％，但仍然很高，需要引起注意。进一步使用分解分析（Blinder-Oaxaca分解）来了解饮食多样性这种时间变化的驱动因素。实证结果表明，就所有八个食物类别和MDD而言，集群代表了最重要的地理差异来源。营养政策应提高教育和意识，缩小社会经济差距，利用媒体，并促进全面的产前保健，以改善柬埔寨的饮食多样性。旨在提高最低膳食多样性摄入量不足的举措应涵盖各个方面，并根据地理和社区环境进行定制。
