Objective To understand the prevalence of anemia in primary and secondary school students in Gansu Province and to provide evidence for the prevention and treatment of anemia in primary and secondary school students. Methods According to the principle of stratified cluster random sampling, 2 998 male and female primary and secondary school students in 5 age groups of 79, 1, 2, 14 and 17 years were collected from Lanzhou City, Tianshui City and Jiuquan City, Gansu Province for determination of hemoglobin. Results A total of 907 anemia students were detected, the detection rate was 30.25%. The detection rate of anemia in boys was 27.57% and that of girls was 32.93%, the difference was statistically significant (u = 3.19, P <0.01). The detection rate of anemia in urban students was 23.48% and that of rural students was 37.03%, the difference was statistically significant (u = 8.07, P <0.01). The detection rate of anemia in primary and secondary school students in Gansu Province in 2010 was significantly higher than that of primary and secondary school students in Gansu Province in 2005. Conclusions The prevalence of anemia among Han Chinese primary and secondary students in Gansu Province is high. Arousing the attention of education and health administrative departments at all levels, comprehensive measures should be taken to improve the anemia status of primary and secondary school students.
