目的了解销售工业盐的临夏回族自治州碘缺乏病病情。方法在临夏回族自治州的临夏、和政和康乐3个县共选8～10岁小学生1258名,孕妇、乳母121人,用便携式B超机检测甲状腺大小;采集孕妇、乳母尿样及当地饮用水水样,采用砷铈催化分光光度法检测尿碘,硫酸铈催化分光光度法检测水碘。结果8～10岁儿童甲状腺肿大率(甲肿率)为17.6%;乳母、孕妇甲肿率为8.3%;孕妇尿碘中位数为76.8μg/L,乳母尿碘中位数为70.9μg/L,二者均<100μg/L;3个县水碘平均为0.22μg/L。结论目前临夏州地方性甲状腺肿病情严重,应在甲肿率>20%的学校投服碘油丸,同时加大健康教育的力度及在这些地区实施碘油与碘盐并重的策略。
Objective To understand the status of iodine deficiency disorders in Linxia Hui Autonomous Prefecture which sells industrial salt. Methods A total of 1258 primary school students aged 8-10 years old, 121 pregnant women and nursing mothers were enrolled in the three counties of Linxia, Hezheng and Kanglai in Linxia Hui Autonomous Prefecture. The size of the thyroid gland was detected with a portable B ultrasound machine. Urine samples from pregnant women, lactating women and local drinking water were collected Urinary iodine was detected by catalytic spectrophotometry with arsenic and cerium and cerium sulfate catalytic spectrophotometry. Results The goiter rate was 17.6% in children aged 8-10 years. The rate of goiter and pregnant women was 8.3%. The median urinary iodine of pregnant women was 76.8μg / L, and the median urinary iodine of pregnant women was 70.9μg / L, both <100μg / L; the average iodine in three counties was 0.22μg / L. Conclusions At present, endemic goitre in Linxia prefecture is in serious condition. She should administer iodized oil in a school with a goiter rate> 20%. At the same time, he should intensify efforts in health education and implement the strategy of equal emphasis on iodized oil and iodized salt in these areas.
