目的 了解母乳喂养婴儿及其乳母碘营养水平 ;动态观察从 1个月月龄至 6个月月龄转乳期时不同喂养方式对婴儿碘营养的影响。方法 对 97名 1个月月龄母乳喂养婴儿尿碘水平进行测定 ,同时检测其乳母乳碘、尿碘水平 ,比较二者关系 ;动态观察 97名婴儿从出生至 6个月月龄 ,按喂养方式分为母乳、混合、人工喂养三组 ,分别检测比较其尿碘水平 ,与 1个月月龄时尿碘水平进行自身对照比较。结果 1个月月龄母乳喂养婴儿尿碘中位数为 183μg L ,提示碘营养状态良好 ,乳母尿碘、乳碘中位数分别为 12 2 μg L、2 0 1μg L ,前者明显低于后者 (P <0 .0 0 1) ;6个月月龄尿碘水平与 1个月月龄比较 ,母乳喂养组较前升高 ,人工喂养组下降 (P均 <0 .0 0 1) ,混合喂养组无明显变化 (P >0 0 5 ) ,3组间差异有显著意义 (P <0 .0 0 5 ) ,母乳及混合喂养组明显高于人工喂养 (P均 <0 .0 0 1) ,母乳喂养组婴儿尿碘中位数最高。结论 母乳喂养儿碘营养状态良好 ,乳母碘营养不足 ;转乳期婴儿碘营养呈下降趋势 ,部分人工喂养婴儿存在碘营养不良
Objective To understand the iodine nutrition of breastfed infants and their lactating mothers. To observe dynamically the effects of different feeding modes on iodine nutrition in infants during one-month-old to six-month-old lactation. Methods Ninety-nine month-old infants were tested for urinary iodine levels and milk iodine and urinary iodine levels. The relationship between the two groups was also observed. From the birth to 6 months of age, Methods were divided into breast milk, mixed, fed three groups were detected and compared the level of urinary iodine, with 1 month old urine iodine levels compared with their own control. Results The urinary iodine median of 1 month old breastfed infants was 183 μg L, which indicated that the iodine nutrition status was good. The urinary iodine and milk iodine median of lactation were 12 2 μg and 210 μg L, respectively, the former was significantly lower than the latter (P <0.01). Urinary iodine level at 6 months of age was higher than that at 1 month of age in breastfeeding group and decreased in artificial feeding group (all P <0.01) There was no significant change in the mixed feeding group (P> 0.05). The differences among the three groups were significant (P <0.05), and the levels in breast milk and mixed feeding group were significantly higher than those in artificial feeding group (P <0.05) ), Breastfed infants had the highest urinary iodine median. Conclusion The status of iodine nutrition in breastfeeding children is good and the iodine nutrition of lactation mother is deficient. The iodine nutrition of infants in transferring milk shows a declining trend. Some artificial feeding babies have iodine malnutrition
