为了调查北京地区孕妇体内碘含量情况,采用温和消化—砷铈催化分光光度法,对1062例妊娠妇女分别做了尿碘含量测定。结果显示:①全民食盐加碘后,北京地区孕妇的尿碘含量90％以上基本在正常水平,中位数为216μg/L。②1062孕妇当中,重度碘缺乏者5例,中度13例,轻度47例,缺碘人数占总被检测人数的6.40％,高于800μg/L者有11例,约占1％。③碘缺乏在妊娠早期、晚期的尿碘含量均明显低于妊娠中期。④年龄在25岁以下和36岁以上组其尿碘含量低于26～30岁和31～35岁组。
In order to investigate the iodine content of pregnant women in Beijing, urinary iodine levels were determined on 1062 pregnant women using mild digestion-arsenic-cerium catalytic spectrophotometry. The results showed that: (1) After universal salt iodization, the urinary iodine content of pregnant women in Beijing area was basically above 90%, with a median level of 216 μg / L. Among 10262 pregnant women, there were 5 severe iodine deficiency patients, 13 moderate ones and 47 mild ones. The number of iodine deficiency accounted for 6.40% of the total number of detected ones. Eleven patients were higher than 800μg / L, accounting for 1%. ③ iodine deficiency in early pregnancy, late urinary iodine levels were significantly lower than in the second trimester. (4) The urinary iodine content of patients under 25 years old and over 36 years old was lower than that of 26-30 years old and 31-35 years old group.
