摘要
目的调查杭州市淳安县儿童碘营养状况,分析山区儿童甲状腺肿大率(甲肿率)回升的原因。方法采用随机整群抽样的方法抽取8～10岁儿童642名。用触诊法对每个儿童检查甲状腺,部分儿童检测尿碘、盐碘、智商、血清总蛋白及调查其膳食情况。结果山区学生甲肿率为10．28%,明显高于城镇学生(3．32%),两组比较差异有统计学意义(P＜0．05)；山区住校生甲肿率(13．81%)与山区未住校生(6．90%)差异有统计学意义(P＜0．05)；城镇学生与山区未住校生甲肿率差异无统计学意义(P＞0．05)；山区住校生的食物种类和每日碘摄入量平均分别为4．9种和26．01μg/d,均低于城镇学生(11．5种、38．05μg/d)。结论山区儿童特别是山区住校生碘摄入量低且不持续及食物中蛋白质较少是导致甲肿率回升的主要原因,应采取措施改善其营养状况。
Objective To investigate children＇s nutritional status of iodine in Chun＇an, a mountainous suburb of Hangzhou and analyze the cause of resurgent goiter rate of this county. Methods Cluster sampling method was used to sample 642 children from eight to ten years old, and palpation was applied to check the size of their thyroid gland. Their urinary iodine, iodized salt, intelligence quotient （IQ）, serum total protein were detected and their nutritional status was investigated as well. Results Goiter rate of countryside pupils was 10.28%, which was higher than of that of town pupils （3.32%）. The difference showed a statistical significance （P 〈 0.05）. Goiter rate of boarding pupils was 13.81%, which was higher than that of nonresident pupils （6.90%） with a statistical significance （P 〈 0.05）. There was no significance between town pupils and nonresident students of mountainous area in goiter rate （P 〉 0.05）. The average of kinds of food and iodine taken daily by boarding pupils was 4.9 and 26.01 μg/d, respectively, which was lower than that of town pupils （11.5 and 38.05 μg/d）. Conclusions Resurgent goiter rate is mainly resulted from low and intermittent of iodine and protein intake, and thus measures should be taken to improve their nutritional status.
