Anaemic women (Hg concentration less than 120 g/l) who participated in a population study of women in Göteborg, Sweden were compared to the women in the population sample as a whole. Due to the way of sampling and a high participation rate the sample was representative of women in Göteborg in the ages studied (age strata between 38 and 60). In the same way the anaemic women were representative of anaemic women in the same general population. Iron deficiency was found to be the main reason for the anaemia in the ages of 38-50 years. Except for big menstrual blood losses in anaemic women no reason for iron deficiency could be found. History of infectious diseases was about as common in anaemic women as in women in the total population sample. Sleeping habits, time off work and physical activity at work and during leisure time were similar in anaemic women and in women in the general population. The proportion of women who reported subjective feeling of tiredness was also similar.
参与瑞典哥德堡一项女性群体研究的贫血女性（血红蛋白浓度低于120 g/l）与总体人群样本中的女性进行了比较。由于抽样方式和高参与率，该样本在研究年龄（38至60岁年龄层）上代表了哥德堡的女性。同样，贫血女性也代表了同一总体人群中的贫血女性。研究发现，缺铁是38至50岁年龄段贫血的主要原因。除了贫血女性月经量过多外，未发现缺铁的其他原因。贫血女性中传染病史与总体人群样本中的女性大致相同。贫血女性与总体人群中的女性在睡眠习惯、工作休假时间以及工作和休闲时间的身体活动方面相似。报告有主观疲劳感的女性比例也相似。
