[Method] The data of Hb detection in primary and secondary school students in Liaoyuan City from 2005 to 2008 were analyzed.

The prevalence of anemia among primary school students, middle school students and high school students dropped year by year (P <0.01). The primary school girls showed a decreasing trend year by year (P <0.01), the junior middle school boys showed a decreasing trend (P <0.01) All in 2007 and 2008 decreased significantly compared with 2005 and 2006 (P <0.01).
