【Objective】 To evaluate the growth situation and the prevalence of anemia of students in primary school for children of migrant workers in Minhang district, Shanghai and the dietary nutrients status of anemic students, to provide evidence for anemia prevention and intervention among migrant workers' children. 【Methods】 By random sampling, two primary schools for children of migrant workers including 2 513 students aged 6 to 13 were selected from Shanghai. Their height and weight were measured. 60% of students diagnosed with anemia were investigated on 24-hour dietary survey of three consecutive days. 【Results】 Girls were at higher risk for underweight(OR=1.49) and boys were at higher risk for overweight(OR=5.53). The prevalence of anemia was 10.3%. Height, BMI and age showed positive correlation with the value of Hb(r=0.204、0.346、0.440,P<0.05). The anemic children were at higher risk for stunting(OR=1.76) and underweight(OR=1.78). The proportion of the ratio of calcium, zinc, vitamin A, vitamin C intakes under the 60％AI or RNI for subjects were 72.1%, 48.3%, 45.6%and 32.7% respectively. 【Conclusions】 The anemia of migrant workers' children is a high prevalence, anemia can affect growth and development. For the anemic students, intakes of energy and nutrients are not enough and the dietary pattern is unreasonable.Improving nutritional status is the key to prevent anemia and promote growth.
