This survey was conducted in Greater Buenos Aires to assess the iron nutritional status of non-pregnant women of child-bearing age. One hundred and eighty-four subjects aged 16-44 years were studied. The prevalence of anaemia (haemoglobin concentration less than 120 g/l) was 25.8 per cent. According to the multiple criteria approach, 21.6 per cent of women presented two or three abnormal values of iron status indicators (free erythrocyte protoporphyrin, serum ferritin and/or mean corpuscular volume). Prevalences of anaemia were 19.2 per cent, 51.8 per cent and 100 per cent in women with 0-1, 2 or 3 indicators in the abnormal range, respectively. The haemoglobin shift analysis showed a prevalence of anaemia of 19.5 per cent. Frequency distribution of iron stores was calculated as described by Cook & Finch, with slight modifications; median value of iron stores was estimated at 180 mg iron. Depletion of iron stores was significantly associated with the socio-economic status, prevalences being 5.3 per cent, 34.2 per cent and 43.2 per cent for the high, middle and low socioeconomic groups, respectively.
本次调查在大布宜诺斯艾利斯地区开展，旨在评估育龄非孕妇的铁营养状况。研究了184名年龄在16至44岁之间的受试者。贫血（血红蛋白浓度低于120 g/l）的患病率为25.8%。根据多标准方法，21.6%的女性出现两项或三项铁状态指标（游离红细胞原卟啉、血清铁蛋白和/或平均红细胞体积）异常。在异常范围内指标数为0至1项、2项或3项的女性中，贫血患病率分别为19.2%、51.8%和100%。血红蛋白变化分析显示贫血患病率为19.5%。铁储备的频率分布按照Cook和Finch所述方法计算，并略作修改；铁储备的中位数估计为180 mg铁。铁储备耗竭与社会经济地位显著相关，高、中、低社会经济群体的患病率分别为5.3%、34.2%和43.2%。
