To understand the role of iron fortified soy sauce( IFSS) on the decrease of anemia prevalence in Chinese population in 2004- 2013.
Meta analysis was used to analyze the effect of IFSS on anemia through published randomcontrol studies on the population intervention with IFSS. Integrated with other data from IFSS statistic on IFSS production and consumption, the recovered population from IFSS was identified and anemia decrease determined, therefore, IFSS contribution to anemia change could be estimated.
By Meta analysis, the anemia rate of the population consumed IFSS was 27% compared with the anemia rate of the population non-consumed IFSS. In the past 10 years, IFSS had covered more than 186 millions population with effect validity time. A total of 28. 49 millions anemic population recovered from anemia. To recover one anemic with IFSS, the cost was 0. 12 RMB.
IFSS has showed effect on the decline of anemia prevalence in last decade, 23. 2% of the decrease was estimated owe to IFSS project, but there are unidentified factors which may bring bias to the result.
了解2004 - 2013年铁强化酱油（IFSS）在中国人群中对降低贫血患病率的作用。
采用Meta分析，通过已发表的关于铁强化酱油人群干预的随机对照研究，分析铁强化酱油对贫血的影响。结合铁强化酱油生产和消费的统计数据，确定铁强化酱油覆盖人群，判断贫血减少情况，从而估算铁强化酱油对贫血变化的贡献。
通过Meta分析，食用铁强化酱油人群的贫血率为27%，而未食用铁强化酱油人群的贫血率为[此处原文缺失未食用人群贫血率数据]。在过去10年中，铁强化酱油有效覆盖人群超过1.86亿。共有2849万贫血人群恢复正常。用铁强化酱油使一人恢复正常的成本为0.12元人民币。
过去十年铁强化酱油对降低贫血患病率有作用，估计23.2%的患病率下降归因于铁强化酱油项目，但存在未明确因素可能给结果带来偏倚。
