Distribution of iron status among urban Chinese women

背景与目的：评估不同年龄和贫血状况女孩和成年女性的血清铁蛋白、血清转铁蛋白受体和铁储量的分布情况。方法与研究设计：2010年中国居民营养与健康状况监测中，对1625名普通女性和1372名贫血女性分别测定其血清铁蛋白、血清转铁蛋白受体和高敏C反应蛋白浓度。结果：6-11、12-17、18-44、45-59和≥60岁不同年龄组女性之间血清铁蛋白、血清转铁蛋白受体和铁储量的分布显著不同。在普通女性组和贫血女性组中，18-44岁年龄组的女性铁营养状况均为最差，其次为12-17岁年龄组。在12-17、18-44、45-59和≥60岁年龄组中，贫血女性的铁营养状况显著低于普通女性组。结论：不同年龄组及贫血状况女性的铁营养状况分布不同，贫血组女性的铁营养状况较普通女性组差。本研究观察到的中国大城市女性铁营养状况的数据，支持开展针对女性的铁营养改善的项目规划，也需要调查男性铁营养状况，并探究可能与铁摄入或损失的发病机制。

Background and Objectives: To assess the distribution of serum ferritin, serum soluble transferrin receptor and body iron among girls and women by age and anaemia. Methods and Study Design: Serum ferritin, serum soluble transferrin receptor and high sensitive C-reactive protein of 1625 and 1372 women in general and anaemic were measured in the National Health and Nutrition Survey commenced in 2010. Results: The distributions of serum ferritin, serum soluble transferrin receptor and body iron for 6-11-y, 12-17-y, 18-44-y, 45-59-y and ≥60-y subgroups were significantly different. Both in population-representative women and those anaemic, the iron status of 18-44-y women was the lowest and that of 12-17-y girls the second lowest. The iron status of anaemic women was lower than that in representative women at ages 12-17 y, 18-44 y, 45-59 y and ≥60 y. Conclusion: Iron status in women of different ages and anaemic had different distributions, but consistently lower than that of population-representative women. The observed iron status of Chinese urban women supports program planning for iron nutrition promotion in women. Iron status information is also needed for men and to understand the pathogenesis which may be related to intake or loss.
