Objective To analyse of the Tibet autonomous region children under the age of five malnutrition and anemia status and its influencing factors in Changdou people's Hospital,and to provide scientific evidence for children nutrition related policy and strategy. Methods Totally 1 208 hospitalized children were extracted using cluster random sample method,child nutrition and anemia condition by the Z score method and hemoglobin value evaluation were analyzed by Logistic regression analysis of possible influence factors,SPSS13.0 was used to software for statistical analysis. Results The growth of children hospitalized delay rate of 12.2%,low weight at a rate of 8.2%,angular rate of 6.8%,anaemia of 20.2%,children's growth delay rate,low rate of weight,angular rate and anaemia in various months between group differences were statistically significant (P<0.01),of which 24~36 months of age group delay rate,the highest growth rate of low weight,angular rate and the peak of the disease by anaemia in 6~12 months of age,gender differences between every months of age group were no statistical significance (P>0.05).Multi-factor analysis results showed that the influence factors of children's growth retardation was birth weight (OR=1.001),the influence factors of low birth weight had months of age (OR=1.018),birth weight (OR=1.001),the influence factors of thin have months of age (OR=1.052) and birth weight (OR=1.001),the influence factors of anemia for months (OR=1.028). Conclusion The Tibet autonomous region to prosperous city people's hospital of malnutrition in hospitalized children under five years old,and still more severe anemia condition,should be for all ages child malnutrition status characteristic formulation corresponding intervention measures,so as to improve the nutrition and health condition of local children.
