[Preliminary analysis of the hemoglobin levels of children under 6 years of age].

Among the 40 survey sites in the "China Food and Nutrition Surveillance Project", we picked six sites to estimate the Levels of preschool children and collected 2416 valid cases. Our analysis formed the following results: Children anemia prevalence level was 16.8%, which was higher than the figure from the "Third National Nutrition Survey in 1992", and was lower than that from the Nutrition Surveillance and Improvement Project in 101 poor countries". The situation where the anemia prevalence was above 20% existed not only in poor rural villages, but also in other rural areas in general as well as cities. Looking at different age structures, we found that the anemia prevalence level was the highest for children aged six to twelve months. The number was as high as 30.90%, consistent with results from many earlier research projects.
