Investigation of 122 women early in the second trimester of pregnancy who complained of constant dizziness during pregnancy, and used traditional "black rings on their middle fingers" as a prophylactic measure, revealed that 59% were anaemic (haemoglobin less than 10 g/100 ml). None of them had blood pressure above 120/70 mmHg. After two months of treatment with ferrous gluconate 300 mg three times daily, folic acid, weekly antimalarial drug, and individual regular nutrition counselling, the incidence of anaemia was reduced to 22.7%. The mean haemoglobin levels before and after initiation of drug therapy were 8.5 and 10.8 g/100 ml respectively. There was a significant difference between the two means (P less than 0.05). There was also a marked difference between the mean haemoglobin levels of ring-wearers and non-ring-wearers in the less educated members of the two groups (P less than 0.001). It can be inferred from this study that the wearing of black rings indicates that the patients are likely to be anaemic, and that educated women seem less likely to rely on this type of traditional treatment of pregnancy anaemia.
对122名妊娠中期早期抱怨孕期持续头晕且使用传统“中指戴黑环”作为预防措施的女性进行调查发现，59%的女性贫血（血红蛋白低于10g/100ml）。她们中无人血压高于120/70mmHg。在用葡萄糖酸亚铁300mg每日三次、叶酸、每周一次抗疟药及个体化定期营养咨询治疗两个月后，贫血发生率降至22.7%。药物治疗开始前后的平均血红蛋白水平分别为8.5g/100ml和10.8g/100ml。这两个均值之间存在显著差异（P<0.05）。两组中受教育程度较低的成员中，戴环者和不戴环者的平均血红蛋白水平之间也存在显著差异（P<0.001）。从这项研究可以推断，戴黑环表明患者可能贫血，且受过教育的女性似乎不太可能依赖这种传统的孕期贫血治疗方法。
