We assessed the prevalence of anemia among schoolchildren in western China as determined by seven cross-sectional surveys involving 12,768 children aged 8-12 years. Subjects were selected randomly from 283 primary schools in 41 economically disadvantaged counties of Ningxia, Qinghai, Shaanxi and Sichuan Provinces. Data were collected through questionnaires and hemoglobin levels were measured. The anemia prevalence was 34% using the WHO hemoglobin cutoff of < 120 g/l. Boarding students and girls were more likely to be anemic. The prevalence of anemia in schoolchildren was high. Iron deficiency is a significant nutrition issue in China.
我们通过对12768名8至12岁儿童进行的七项横断面调查，评估了中国西部学童的贫血患病率。研究对象是从宁夏、青海、陕西和四川省41个经济欠发达县的283所小学中随机选取的。通过问卷调查收集数据，并测量血红蛋白水平。按照世界卫生组织血红蛋白临界值<120 g/l计算，贫血患病率为34%。寄宿学生和女生更易患贫血。中国学童的贫血患病率较高。缺铁是中国一个重要的营养问题。
