目的探讨碘营养补充预防脑发育关键期婴幼儿碘缺乏所致智能发育障碍的效果。方法随机选取成都缺碘地区孕妇、哺乳期妇女及3岁以内断奶婴幼儿各30例为对照组,同时选取该地区孕妇、哺乳期妇女及3岁以内断奶婴幼儿各30例为观察组。观察组服用碘油进行碘营养补充,对照组不服用碘油,不补充碘营养。1年后,检测孕妇、哺乳期妇女、3岁内断奶婴幼儿的尿液尿碘含量及3岁内断奶婴幼儿的发育商。结果 1年后,观察组孕妇、哺乳期妇女、3岁内断奶婴幼儿的尿碘含量均明显高于对照组,观察组3岁内断奶婴幼儿的发育商评分为明显高于对照组,差异有统计学意义(P<0.05)。结论碘缺乏会导致脑发育关键期婴幼儿出现致智能发育障碍的情况,及时给予其碘营养补充,可有效改善碘缺乏所致智能发育障碍的程度。
Objective To investigate the effect of iodine nutrition supplementation on the prevention of mental retardation caused by iodine deficiency in infants and young children at critical stages of brain development. Methods Thirty pregnant women, lactating women and weaned infants under 3 years old were randomly selected as the control group, and 30 pregnant women, lactating women and infants under 3 years old in this area were selected as the observation group. The observation group took iodized oil for iodine nutrition supplementation, the control group did not take iodized oil, did not add iodine nutrition. One year later, urine iodine levels in pregnant women, lactating women, infants under 3 years of age, and infants under 3 years of weaning were tested. Results One year later, urinary iodine contents of pregnant women, lactating women and weaning infants in observation group were significantly higher than those in control group. The developmental score of infants in observation group was significantly higher than that of control group There was statistical significance (P <0.05). Conclusion Iodine deficiency can lead to mental retardation of infants and young children in the critical period of brain development. The timely administration of iodine nutrition supplement can effectively improve the degree of mental retardation caused by iodine deficiency.
