Abstract: Objective To understand the distribution of anemia among 6~24 months young infants in 3 counties of Guangxi where the incidence of anemia were high,and analyse the influence of different intervention methods on the 6~24 months young infants. Methods The survey was conducted according to stratified cluster sampling method in regions with a high incidence of anemia in Guangxi.Finally,504 aged 6~24 months infants with their parents were extracted from 3 counties and 8 townships and divided into A,B,C,D 4 groups to carry out a questionnaire survey and different intervention trials.Also,comparative analysis anemia and outcomes were carried out before and after the intervention. Results The 4 groups had no statistically significant differences (χ²=0.56,P=0.905) in gender but had statistically significant differences in prevalence of anemia(χ²=13.81,P=0.003);Order of prevalence of anemia showed B>A>D>C.The prevalence of anemia was decreased after intervention trials(P<0.001).Later order changed as C>D>A>B.Before and after intervention,there was also with statistical significance (χ²=26.64,P<0.001)in the outcomes of anemia. Conclusion Supplementary nutrient for 6~24 months young infants is conducive to improving the status of anemia and reduce the prevalence of anemia.
