Iron deficiency anaemia is a most common micronutrient deficiency affecting mostly the low socioeconomic populations of the developing world. The objective of this study was to evaluate the feasibility of iron fortification of household drinking water to prevent iron deficiency anaemia among members of the low socioeconomic families of Southern Brazil. A total of 21 low socioeconomic families representing 88 subjects including 1-6 years old children whose haemoglobin level was between 10 and 12 g/dl were selected to participate in this study. Nine families in the control group were supplied with placebo solution and 12 families in the experimental group were supplied iron solution with ascorbic acid to be added to their domestic drinking water over a period of 4 months. The feasibility and acceptability of iron fortified drinking water was assessed through home visits and questionnaires. Blood samples were collected at the beginning and after 4 months of the study for the determination of haemoglobin and serum ferritin levels. The results of this study indicated that iron fortified drinking water was well received by the low socioeconomic families and that it was effective in improving the haemoglobin and serum ferritin levels. It can be concluded from this study that iron fortification of household drinking water is a simple and effective alternative for developing countries along with other technological approaches to iron fortification of foods.
缺铁性贫血是一种最常见的微量营养素缺乏症，主要影响发展中世界社会经济地位较低的人群。本研究的目的是评估家庭饮用水铁强化对预防巴西南部社会经济地位较低家庭成员缺铁性贫血的可行性。总共选取了21个社会经济地位较低的家庭，代表88名受试者，包括血红蛋白水平在10至12 g/dl之间的1至6岁儿童，参与本研究。对照组的9个家庭供应安慰剂溶液，实验组的12个家庭供应添加了抗坏血酸的铁溶液，在4个月的时间里添加到他们的家庭饮用水中。通过家访和问卷调查评估铁强化饮用水的可行性和可接受性。在研究开始时和4个月后采集血样，以测定血红蛋白和血清铁蛋白水平。本研究结果表明，铁强化饮用水受到社会经济地位较低家庭的欢迎，并且在提高血红蛋白和血清铁蛋白水平方面是有效的。从这项研究可以得出结论，家庭饮用水铁强化是发展中国家一种简单有效的替代方法，与其他食品铁强化技术方法一样。
