摘要
本文采用整群抽样法,随机抽取静安区三所学校,研究对象为873名10～17岁青少年。缺铁和贫血的患病率分别为13.17％和9.84％,配对病例对照研究表明蛋白质供给量低于1.2g/kg,蛋白质占总热量的比例低于12％是缺铁和贫血的重要危险因素,比数比分别为1.8和1.7(P<0.05),此外尚发现月经过多和慢性失血也是缺铁和贫血重要危险因素,比数比分别为2.7和4.3P<0.05)。缺铁和贫血可影响青少年的生长发育。
Using cluster sampling method, 3 schools were randomly selected out of all the schools in Jingan District. 873 adolescents aged 10-17 years were available for the study of their iron nutritional status. The prevalences of iron deficiency (ID) and anemia were 13.17% and 9.84% respectively. The matched case-control study showed that low protein intake of less than 1.2g/kg and protein calories less than 12% of total caloric intake were the important contributing factors. The ORs were 1.8 and 1.7 respectively (P<0.05).Heavy menstruation and chronic blood loss were also important contributing factors with ORs 2.7 and 4.3 respectively (P<0.05). The growth of adolescents could be influenced by the ID and anemia.
