缺碘地区补碘后哺乳期妇女尿碘乳碘及甲状腺功能研究

The study on urine iodine,milk iodine and thyroid function of breast feeding women after iodine supplementation in iodine deficiency area

目的 了解缺碘地区食用合格碘盐的哺乳期妇女产后半年的碘代谢状况。方法 对乳母及婴儿进行随访观察 ,测定尿碘 ,乳碘及甲状腺激素。结果 产妇分娩时尿碘值为 115 .2 8～ 913.0 2μg/ L ,中位数 42 3.5 8μg/ L ;由于围产期低盐饮食 ,90 %产妇在产后半年内尿碘水平逐渐下降 ,婴儿尿碘随之变化 ;但绝大多数乳母和婴儿尿碘处于正常碘营养水平。乳碘始终处于较高水平 ;部分产妇的甲状腺激素 TT4水平偏高 ,提示 :产妇分娩前后甲状腺功能代偿性增强。结论 在食用合格碘盐的条件下 ,哺乳期妇女碘营养基本处于正常水平。但由于饮食、生活习惯等诸因素影响 ,约 2 0

Objective To investigate the metabolic states on iodine in breast feeding women taking qualified iodine salt in iodine deficiency area within half a year after delivery.Methods Determination of milk iodine,urine iodine and thyroid function.Results Urine iodine on delivery was 115.28~913.02μg/L.Median of urine iodine was 423.58μg/L.Urine iodine level of 90% of the mothers dropped gradually in half a year after delivery because of low iodine salt intake,and meanwhile the urine iodine level of infants changed correspondingly.The milk iodine level always kept in high level.The level of TT 4 in some parturients were a little high.It showed that the thyroid function of parturients increased compensatorily before and after delivery.Conclusions The iodine level of breast feeding women was basically normal by way of taking qualified iodine salt.But some factors (such as eating,living conditions) may cause that the urine iodine level about 20% of the mothers were a little low.
