Cow milk is an important source of macro-and micronutrients. However, it has low iron content but high content of casein and calcium thus could negatively influence hemoglobin synthesis. On the other hand, camel milk contains higher iron concentration than cow milk. In addition, the majority of iron in camel milk is associated with the lower molecular fraction of casein suggesting better bioavailability. Furthermore, vitamin C concentration, a useful iron absorption enhancer, is more than three-fold greater in camel milk than cow milk. This study compared hemoglobin concentration among young children consuming consistently cow milk or camel milk.
Hemoglobin concentration of young children (aged 6-59 mo) from settled pastoralist communities of the Somali region, Ethiopia, consistently consuming cow milk (n = 166) or camel milk (n = 166) was determined. In addition, socio-demographic and water, sanitation, and hygienic (WASH) conditions of study participants' households were captured. Furthermore, dietary intake and anthropometric characteristics of participating children were assessed.
Among the participating children, 38.6% were underweight, 33.4% were stunted, and 34.5% were wasted. In addition, 77.4% of children were anemic. The present study households had poor WASH conditions. Only 0.6% of children had the minimum acceptable dietary diversity. There was small but significant mean hemoglobin difference among camel milk and cow milk consuming children (9.6±1.8 g/dl vs 9.1±2.2 g/dl; p = 0.012). In addition, the odds of low hemoglobin concentration was greater among cow milk consuming children than camel milk consuming children [AOR 2.17; 95 CI; 1.39, 3.37; p = 0.001]. However, the overall anemia prevalence among the two groups was similar.
Camel milk consumption is associated with better hemoglobin concentration but may not be sufficient to prevent anemia in populations from resource poor settings. The etiology of anemia is multifactorial thus further studies on the link between milk consumption and hemoglobin concentration are important.
牛奶是宏量和微量营养素的重要来源。然而,它的铁含量低,而酪蛋白和钙含量高,因此可能会对血红蛋白合成产生负面影响。另一方面,骆驼奶的铁含量高于牛奶。此外,骆驼奶中的大多数铁与较低的酪蛋白分子部分相关,提示生物利用度更好。此外,维生素 C 浓度(一种有用的铁吸收增强剂)是牛奶的三倍多,而骆驼奶的铁吸收增强剂是牛奶的三倍多。本研究比较了持续食用牛奶或骆驼奶的幼儿的血红蛋白浓度。
在埃塞俄比亚索马里地区定居牧民社区中,6-59 月龄的幼儿持续食用牛奶(n=166)或骆驼奶(n=166),测定其血红蛋白浓度。此外,还记录了研究参与者家庭的社会人口统计学和水、环境卫生和个人卫生(WASH)条件。此外,还评估了参与儿童的饮食摄入和人体测量特征。
在所参与的儿童中,38.6%体重不足,33.4%发育迟缓,34.5%消瘦。此外,77.4%的儿童贫血。本研究家庭的 WASH 条件较差。只有 0.6%的儿童具有最低可接受的饮食多样性。食用骆驼奶和牛奶的儿童之间的平均血红蛋白差异虽小但有统计学意义(9.6±1.8 g/dl 与 9.1±2.2 g/dl;p=0.012)。此外,与食用骆驼奶的儿童相比,食用牛奶的儿童低血红蛋白浓度的可能性更大[比值比 2.17;95%置信区间;1.39,3.37;p=0.001]。然而,两组的总体贫血患病率相似。
骆驼奶的消费与更好的血红蛋白浓度有关,但在资源匮乏的人群中,可能不足以预防贫血。贫血的病因是多因素的,因此进一步研究牛奶消费与血红蛋白浓度之间的关系很重要。
