Abstract
【Objective】 To assess current anemia prevalence and related factors of students aged 10～11 years in primary schools of Shanghai. 【Methods】 Using multi-stage cluster sampling, the sample was selected in accordance with the "District-School-Grade" line of the sampling technique in shanghai. A total of 10 primary schools from 10 districts were selected. In each primary school, all the students of Grade 5 were selected. Finally, 1 675 children aged 10～11 years were investigated by using health questionnaire survey and anemia screening according to WHO criteria. Logistic regression and correlate analysis were used to study the risk factors. 【Results】 The rate of anemia was 2.7％(2.5% in male, 3.0% in female). There was no significant difference between the prevalence of anemia in boys and that in girls(χ2=1.080,P=0.583). There was statistically significant difference between the prevalence rate of anemia in urban students and that in non-urban students, the prevalence of anemia in group of non-urban students was higher(χ2=4.969,P=0.026). There were statistically significant difference between the prevalence rate of anemia in students whose father often smoked and that of children whose father did not, the prevalence rate of anemia in students whose father often smoked was higher(χ2=5.359,P=0.021). It was revealed by Logistic regression analysis that the risk factors of anemia were poor appetite, students whose father often smoked and students from non-urban districts. 【Conclusions】 Anemia exist among students aged 10~11 years in Shanghai. It is necessary to provide healthy knowledge to children and their parents, providing good environment for the children.
