使用采用基图巴语言的考夫曼儿童评估套组 (K-ABC) 对扎伊尔农村一所教会学校的 47 名一年级小学生进行了认知能力测试。在该测试的一天内，对每个孩子的血液血红蛋白 (Hgb) 水平和肠道寄生虫的存在进行了评估。一半的儿童接受为期 30 天的铁补充剂（20 毫克铁），而那些对强直虫或蛔虫肠道寄生虫呈阳性的儿童被随机选择接受驱虫治疗或安慰剂。治疗开始 4 周后，所有儿童再次接受医学和认知评估。通过判别分析，治疗后 1 个月 K-ABC 心理处理综合表现与血液 Hgb 增加相结合，成功分类了 74% 的儿童是否同时接受了铁补充剂和驱虫治疗 (p = .007)。关于我们对每个孩子的家庭评估，与家庭环境的营养和经济福祉相关的因素被证明是同步处理能力的可靠标志。然而，目前的研究结果还表明，在短期内，伴随驱虫剂和铁补充剂治疗的血液 Hgb 的变化可以改善认知能力的某些方面，也许是通过提高注意力能力来改善。
Tested 47 first-year primary school children at a mission school in rural Zaire for cognitive ability with the Kaufman Assessment Battery for Children (K-ABC) adopted to the language of Kituba. Within a day of this test, each child was evaluated for blood hemoglobin (Hgb) level and the presence of intestinal parasites. Half of the children received an iron supplement (20 mg Fe) for 30 days and those children positive for the intestinal parasites of ankylostome or ascaris were randomly selected to receive either a vermifuge treatment or placebo. All of the children were again evaluated medically and cognitively 4 weeks after the initiation of treatment. Using discriminant analysis, performance on the Mental Processing Composite of the K-ABC 1 month after treatment in combination with increases in blood Hgb resulted in the successful classification of 74% in terms whether a child had received both iron supplement and vermifuge treatment (p = .007). With respect to our home evaluation for each child, factors related to the nutritional and economic well-being of the home environment proved a reliable marker for Simultaneous Processing ability. However, the present findings also suggest that over the short-term, changes in blood Hgb that accompany both vermifuge and iron supplement treatment together can improve certain aspects of cognitive ability, perhaps by means of heightened attentional capacity.
