在印度尼西亚西爪哇的一个橡胶种植园，大约88%的成年男性工人患有钩虫感染，超过45%的人贫血，根据血红蛋白低于13 g/100 ml判断。采穗者和除草者的Hb值和哈佛台阶试验（HST）表现显著相关。橡胶割胶工人的工资是根据他们的工作产出计算的，他们的收入与血红蛋白水平相关。血红蛋白水平和Mortocell也相关。热量摄入与工作输出或HST表现无关。用100 mg元素铁治疗60天，导致贫血个体的血液学状态以及他们的HST表现、工作输出和发病率显著改善。治疗组和安慰剂组每天获得相当于最低日工资5-7%的奖励。这笔钱主要花在食物上，导致增加了3-5毫克有效铁和50毫克维生素C的摄入量。这可能解释了贫血安慰剂组Hb、HST表现、工作输出和发病率的显著但较小的改善。在未接受治疗的子样本中，没有支付任何费用，Hb，红细胞压积，工作表现，HST评分或疾病发病率没有变化。在停止收入补充后，安慰剂组的Hb和红细胞压积水平及相关变化在30天内恢复到初始水平，但在铁治疗组中没有变化。与提高生产力和降低发病率的经济效益相比，铁补充剂的成本很小。
Approximately 88% of adult male workers on a rubber plantation in West Java, Indonesia, had hookworm infection and over 45% were anemic as judged by a Hb below 13 g/100 ml. Hb values and Harvard Step Test (HST) performance for tappers and weeders were significantly correlated. The rubber tappers were paid by their work output, and their earnings correlated with Hb levels. Morbidity and Hb levels were also correlated. Caloric intakes were not correlated with work output or HST performance. Treatment with 100 mg of elemental Fe for 60 days resulted in a significant improvement in hematological status of the anemic individuals and in their HST performance, work output and morbidity. Treatment and placebo groups received a daily incentive payment equivalent to 5-7% of minimum daily wages. This sum, spent largely on food, resulted in added intakes of 3-5 mg of available Fe and 50 mg of vitamin C. This probably explains a significant but lesser improvement in Hb, HST performance, work output and morbidity in the anemic placebo group. In an untreated subsample to whom no payment was given, no change in Hb, hematocrit, work performance, HST score or disease morbidity occurred. After income supplementation was stopped, Hb and hematocrit levels and related changes reverted to initial levels within 30 days in the placebo groups, but were unchanged in the Fe-treated groups. The cost of the Fe supplementation was small compared with the economic benefits of increased productivity and lowered morbidity.
