Abstract: Objective To explore the status and the influencing factors of nutritional anemia and its association with vitamin A (VA) in migrant children aged 6 to 35 months in Beijing, in order to provide a scientific basis for the effective preventive measures for nutritional anemia in migrant children. Methods By using the convenient cluster sampling method, a cross-sectional survey on 308 children aged 6 to 35 months was conducted in 2017 from the migrant population settlement areas of Chaoyang, Haidian and Changping District in Beijing. Hemoglobin and VA levels were measured. Results The prevalence rate of anemia was 27.92% among migrant children aged 6 to 35 months in Beijing, with 29.19% in boys and 26.53% in girls. There were statistically significant differences among children at different age groups and different regions (P<0.001). And the prevalence rate of anemia was found highest in infants aged 6 to 11 months (52.63%). Children who had formula milk, lean meat, animal liver food had lower risk for anemia significantly (P＜0.05 or <0.01). VA level in children with anemia was significantly lower than that in the control group(P<0.001). Multivariate Logistic regression analysis showed that the residence area, age and VA level were the influencing factors of nutritional anemia(P<0.05 or <0.01). Conclusions The prevalence of nutritional anemia is high among the migrant children aged 6 to 35 months in Beijing, especially in infants aged 6 to 11 months. Children with anemia have significantly lower levels of VA. It is suggested to strengthen the popularization of scientific feeding knowledge and to adjust the dietary structure reasonably among parents of migrant children.
