Abstract

Objective To investigate the incidence of iron deficiency anemia (IDA) and its influence on intellectual development among the Han nationality and the Dongxiang nationality school-aged children in Lanzhou city and Dongxiang county. Methods A total of 396 children aged 6～12 were selected from two schools in Lanzhou City and Dongxiang County by random stratified sampling. The physical development indicators were measured and the blood was collected and questionnaires were investigated. The blood routineand serum iron and other indicators were analyzed. Children conformed to the diagnostic criteria were enrolled in the IDA group,healthy children with similar background were enrolled in the control group. China-Webster Children′s Intelligence Scale (C-WISC) was used to assess the intelligence of children in both groups. Results IDA prevalence rate was 8.6% in this study. The language IQ and total IQ of IDA group were lower than that of the control group,mainly in the C factor; Operating IQ of children in rural areas (Dongxiang county) was lower than that in urban areas (Lanzhou City); In IDA group,the scores of children′s jigsaw puzzles and memorize numbers in Dongxiang County were lower than those in Lanzhou city,and the difference was statistically significant. Conclusions The prevalence of IDA in children is still high in Lanzhou. IDA has a certain influence on children′s intellectual development. And there are some differences on intellectual development between children from urban and rural areas.
