摘要
目的了解浙江省嘉兴市2018—2022年孕妇盐碘和尿碘水平,为指导孕妇科学补碘提供参考依据。方法2018—2022年,分别在嘉兴市7个县(市、区)随机抽取5个乡镇(街道),每个乡镇(街道)抽取21名孕妇,采集其家中食用盐样和随机尿样,分别进行尿碘和盐碘的定量检测。结果2018—2022年嘉兴市共采集孕妇盐样4249份,盐碘中位数为23.3 mg/kg,碘盐覆盖率为88.1%,合格碘盐食用率为83.9%;不同年份和地区孕妇盐碘中位数差异均具有统计学意义(P<0.05)。共检测孕妇尿样4249份,尿碘中位数为129.9μg/L,碘缺乏占59.6%,碘营养适宜占26.3%,碘营养超适宜占12.1%,碘营养过量占2%。仅2022年孕妇碘盐覆盖率和合格碘盐食用率均高于90%,孕妇尿碘中位数达到碘营养适宜水平。不同地区、年龄、孕期和食盐类型的孕妇尿碘均低于碘营养适宜水平,各组间孕妇尿碘中位数差异均具有统计学意义(P<0.05)。结论2018—2022年嘉兴市孕妇碘营养总体未达到适宜水平,存在碘摄入不足的风险,需加强对孕妇科学补碘宣教,持续开展孕妇碘营养监测,制定合理有效的补碘防控策略,提高孕妇碘营养水平。
Objective To understand the salt iodine and urine iodine levels of pregnant women in Jiaxing City from 2018 to 2022,so as to provide reference for guiding pregnant women to supplement iodine scientifically.Methods From 2018 to 2022,21 pregnant women were randomly selected from 5 townships(streets)in 7 counties(cities and districts)of Jiaxing City,and salt samples and random urine samples were collected from their homes for quantitative detection of urine iodine and iodized salt.Results A total of 4249 salt samples were collected from pregnant women in Jiaxing City from 2018 to 2022.The median iodized salt was 23.3 mg/kg,the iodized salt coverage rate was 88.1%,and the qualified iodized salt consumption rate was 83.9%.The median salt iodine of pregnant women in different years and regions had statistical significance(P<0.05).A total of 4249 urine samples from pregnant women were detected.The median urine iodine was 129.9μg/L,59.6%were iodine deficient,26.3%were suitable for iodine nutrition,12.1%were super suitable for iodine nutrition,and 2%were excessive.In 2022 alone,the coverage rate of iodized salt and the consumption rate of qualified iodized salt in pregnant women were both higher than 90%,and the median urine iodine of pregnant women reached the appropriate level of iodine nutrition.The urinary iodine of pregnant women in different regions,age,pregnancy and salt type was lower than the appropriate level of iodine nutrition,and there were statistically significant differences in the median urinary iodine of pregnant women among all groups(P<0.05).Conclusion The overall iodine nutrition of pregnant women in Jiaxing City from 2018 to 2022 had not reached the appropriate level,and there was a risk of insufficient iodine intake.It is necessary to strengthen scientific iodine supplement education for pregnant women,continue to carry out iodine nutrition monitoring for pregnant women,and formulate reasonable and effective iodine supplement prevention and control strategies to improve the iodine nutrition level of pregnant women.
