2019年菏泽市重点人群碘营养状况分析

Analysis on iodine nutrition status of key population,Heze city,2019

目的了解菏泽市改水后重点人群碘营养状况及儿童甲状腺肿病情,为制定防治措施提供科学依据。方法全市9个县区每个县区按东、南、西、北、中每个方位选取2个,共计10个集中供水的居民户水源,检测水碘含量;每个县区按东、南、西、北、中选取5所小学,每个小学选取40名8~10岁学生,男女各20名,检测尿碘含量和甲状腺容积;每个县区选取100名孕妇,检测尿碘含量。结果检测水碘90份,检测值为5.32~374μg/L,中位数为131μg/L,>100μg/L的57份、占比63.33%。检测8~10岁儿童尿碘1800份,尿碘中位数为312μg/L,<100μg/L的66份、占3.67%,100~199μg/L的248份、占13.78%,200~299μg/L的532份、占29.56%,≥300μg/L的954份、占53.00%;8~10岁组尿碘中位数,差异有统计学意义(P<0.01);不同性别尿碘中位数差异无统计学意义(P>0.05)。检测8~10岁儿童甲状腺1800人,肿大9人、占0.50%;8~10岁组甲状腺肿大率差异无统计学意义(P>0.05);不同性别甲状腺肿大率差异无统计学意义(P>0.05)。检测孕妇尿碘900份,尿碘中位数为232μg/L,<150μg/L的126份、占14.00%;150~249μg/L的392份、占43.56%;250~499μg/L的378份、占42.00%;≥500μg/L的4份、占0.44%。结论改水后,高碘水样占比有所下降;儿童甲状腺肿大率在<5%的标准范围内。

Objective To understand the iodine nutritional status of key populations and the condition of children’s goiter after the water reform in Heze city,so as to provide a scientific basis for iodine nutritional prevention and treatment.Methods 2 water sources from the east,south,west,north and middle directions were selected from each of the 9 counties,and a total of 10 households with centralized water supply were used to detect the iodine content of water;5 primary schools were selected from the east,south,west,north and middle of each of the 9 counties,and 40 students aged 8-10 years were selected from each primary school,including 20 boys and 20 girls,and urine iodine content and thyroid volume were tested 100 pregnant women were selected from each of 9 counties,and urine iodine content was detected.Results A total of 90 samples of water iodine were detected,with the detection value of 5.32-374μg/L,and the median of 131μg/L;57 samples(63.33%)contained>100μg/L.A total of 1800 urine iodine samples were tested for children aged 8-10 years old.The median urine iodine was 312μg/L,66 samples were<100μg/L,accounting for 3.67%,248 samples were100-199μg/L,accounting for 13.78%,532 samples were 200-299μg/L,accounting for 29.56%,and 954 samples were≥300μg/L,accounting for 53.00%.The median urinary iodine of the 8-10 year-old group was significantly different(P<0.01).There was no significant difference in the median urine iodine between the sexes(P>0.05).A total of 1800 children aged 8-10 years were tested for thyroid disease,and 9 children(0.50%)had enlarged thyroid.There was no significant difference in the goiter rate between the 8-10 years old group(P>0.05).There was no significant difference in the goiter rate between the sexes(P>0.05).A total of 900 urine iodine samples were collected from pregnant women.The median urine iodine was 232μg/L,and 126 samples were<150μg/L,accounting for 14.00%.392 samples were 150-249μg/L,accounting for 43.56%;378 samples of 250-499μg/L,accounting for 42.00%;4 samples were≥500μg/L,accounting for 0.44%.Conclusion After water improvement,the proportion of high iodine water samples decreased;The goiter rate of children is within the standard range of<5%.
