某部新兵食用碘盐和无碘盐后尿碘及超敏促甲状腺素的比较研究

Changes of urine iodine and thyroid stimulating hormone after non-iodized salt supplement in recruits from Shanghai Armed Police Forces

目的研究无碘盐对碘营养状况及超敏促甲状腺素(sTSH)的影响。方法在同一伙食单位用餐、封闭式训练的新兵分为碘盐组、无碘盐组,比较两组尿碘变化及对sTSH的影响。结果 3个月训练结束后,碘盐组尿碘中位数(median of urinary iodine,MUI)较无碘盐组明显升高,随着MUI升高,碘盐组出现sTSH明显变化。结论在食用普通碘盐情况下,部队官兵可能成为高摄碘人群,应制定出符合部队特点的补碘标准。

Objective To study the effect of non-iodized salt on iodine nutrition and hypersensitive thyroid stimulating hormone（sTSH）.Methods Recruits who ate the same foods during intense-load training were divided into two groups.The first group consumed iodized salt while the second group non-iodized salt.Medians of urinary iodine（MUI） and sTSH were measured and inquired.Results Compared with non-iodized salt group,the median of urinary iodine（MUI） and sTSH greatly increased in iodized salt group after three months＇ training.The level of sTSH was increased with MUI.Conclusions The thyroid function of recruits changes at a high dose of iodine intake during excessive training.The iodine nutrition of the army men should taken into serious consideration.
