This study describes the occurrence of anaemia (haemoglobin level below 12.5 g/dl) amongst National Service (NS) Registrants in Singapore. A total of 32,320 subjects were screened and the prevalence of anaemia was 0.51%. The Indians had the highest prevalence compared to the other races. The commonest cause of anaemia was haemoglobinopathy. Though alpha-thalassaemia is the commonest form of haemoglobinopathy in Singapore, we found that beta-thalassaemia was the commonest form of haemoglobinopathy in anaemic subjects. In the Chinese and Malay races, the commonest cause of anaemia was haemoglobinopathy. For the Indian and Other races, it was iron deficiency. Of all the subjects with haemoglobinopathy, 86.2% did not have a family history of anaemia. Iron deficiency occurred in about a third of the anaemic subjects. The prevalence was highest in the low income groups and the Indian and Other races. But with higher standards of living, blood loss may be a more important cause for iron deficiency than poor nutrition.
本研究描述了新加坡国民服役（NS）登记人员中贫血（血红蛋白水平低于12.5克/分升）的发生情况。总共筛查了32320名受试者，贫血患病率为0.51%。与其他种族相比，印度人的患病率最高。贫血最常见的原因是血红蛋白病。虽然α地中海贫血是新加坡最常见的血红蛋白病形式，但我们发现β地中海贫血是贫血受试者中最常见的血红蛋白病形式。在华族和马来族中，贫血最常见的原因是血红蛋白病。对于印度族和其他种族，贫血原因是缺铁。在所有患有血红蛋白病的受试者中，86.2%没有贫血家族史。约三分之一的贫血受试者存在缺铁情况。患病率在低收入群体以及印度族和其他种族中最高。但随着生活水平提高，失血可能比营养不良更是缺铁的一个重要原因。
