近年来青少年的铁缺乏已引起人们的高度重视。作者调查了爱尔兰西北部Sligo镇(全镇总人口2万人)的五所中学234名(男68名、女148名)四年级学生,占全部四年级学生439名的53%,年龄为14.5～18.4岁(平均15.9岁),调查项目为血红蛋白(Hb)和精确评价铁储备的血清铁蛋白浓度。结果:男生Hb平均为14.3g%(范围为10.3～16.6g%),女生为13.3g%(10.2～15.4g%)。有11名(13%)男生Hb<13.0g%,12名(7%)女生<12.0g%。男生血清铁蛋白浓度平均为17.3μg/L(范围为2.1～87.3μg/L),女生
In recent years, young people’s iron deficiency has caused people’s attention. The authors surveyed 234 fourth-year students (68 males and 148 females) from five secondary schools in Sligo, a town of 20000 in the northwestern part of Ireland, accounting for 53% of 439 students in all fourth graders and aged 14.5 - 18.4 years (mean, 15.9 years) with hemoglobin (Hb) and a precise estimate of serum ferritin concentration in iron reserves. Results: The average male Hb was 14.3 g% (range, 10.3-16.6 g%) and female students was 13.3 g% (10.2-15.4 g%). 11 (13%) boys Hb <13.0g%, 12 (7%) girls <12.0g%. The average concentration of serum ferritin in boys was 17.3μg / L (range 2.1 ~ 87.3μg / L)
