High prevalence of anemia among children has been an important public health concern globally. In Zambia, the prevalence of anemia among children aged 6-59 months was 58%. Previous studies have suggested that feeding a variety of food prevents anemia. However, it is not yet determined if out of several food groups available locally, some foods have played crucial roles in anemia among young children. The objective of this study was to find out the food groups that were associated with childhood anemia among Zambian children aged 6-59 months. We have obtained the individual- level data related to health and nutrition of the Zambia Demographic Health Survey (ZDHS) 2018 with permission. Children's feeding, demographic, and household information were analyzed using logistic regression models. Children who consumed food made from grains (AOR:1.2; 95%CI: 1.01-1.46; p=0.044) and cheese or food made from milk (AOR:2.7; 95%CI: 1.19-6.00; p=0.018) showed relatively higher prevalence of anemia than those who did not. Additionally, malnutrition, mother's anemia and education, and area of living were also significantly associated with prevalence of anemia. Most common food in Zambia is food made from grain. Grain consists of phytic acids which can prevent iron absorption. This is a potential reason for the highlevel anemia among children. Dephytinization strategies should be considered through further studies.
儿童贫血的高患病率一直是全球重要的公共卫生问题。在赞比亚,6至59个月大儿童的贫血患病率为58%。先前的研究表明,多样化饮食可预防贫血。然而,在当地可得的几种食物类别中,尚不确定某些食物是否在幼儿贫血中起关键作用。本研究的目的是找出与赞比亚6至59个月大儿童贫血相关的食物类别。我们已获许可获取了与2018年赞比亚人口与健康调查(ZDHS)相关的个人层面的健康和营养数据。使用逻辑回归模型分析了儿童的饮食、人口统计学和家庭信息。食用谷物制成的食物(调整后比值比:1.2;95%置信区间:1.01 - 1.46;p = 0.044)以及奶酪或奶制品(调整后比值比:2.7;95%置信区间:1.19 - 6.00;p = 0.018)的儿童比未食用者的贫血患病率相对更高。此外,营养不良、母亲的贫血状况和教育程度以及居住地区也与贫血患病率显著相关。赞比亚最常见的食物是谷物制成的食物。谷物含有植酸,会阻碍铁的吸收。这可能是儿童贫血率高的一个原因。应通过进一步研究考虑去植酸策略。
