摘要
目的了解河南省适碘地区成人碘营养状况,为采取针对性防治措施提供依据。方法2022年3—10月,采用横断面调查方法,在河南省适碘行政村≥5个的县(市、区)(共计60个)开展适碘地区成人碘营养监测工作。每个县(市、区)将水碘中位数在40~100μg/L的行政村按水碘值分为40~<50、50~<60、60~<70、70~<80、80~<90、90~100μg/L共6个水碘层,每个水碘层随机抽取1个行政村,每个行政村抽取20~60岁成人20人。采集成人随机1次尿样,检测尿碘含量;并检查甲状腺结节。结果2022年河南省适碘地区共采集20~60岁成人尿样6214份,尿碘中位数为257.0μg/L;安阳市、南阳市、周口市成人尿碘>300μg/L,处于过量水平,其他10个省辖市适碘地区成人碘营养均处于基本适宜水平。共进行5877名成人的甲状腺结节筛查,983名检出甲状腺结节,检出率为16.7%。按照水碘值分组(40~<60、60~<80、80~100μg/L),成人尿碘中位数分别为247.0、260.1、269.6μg/L,组间比较差异有统计学意义(H=11.885,P<0.05);甲状腺结节检出率分别是18.4%、15.0%、16.4%,组间比较差异无统计学意义(χ^(2)=4.471,P>0.05)。结论河南省适碘地区成人碘营养总体处于适宜水平,建议在维持目前防治措施基础上加强监测,根据人群碘营养变化情况及时调整防治措施。
Objective To assess the iodine nutritional status among adults in iodine adequate areas in Henan Province,so as to provide a basis for the development of targeted public hearlth interventions.Methods Conducted from March to October 2022,the study utilized a cross-sectional design,surveying 60 iodine adequate counties with≥5 iodine suitable administrative villages of Henan Province.Villages with median water iodine values ranging from 40 to 100μg/L in each county were categorized into six strata:40-<50,50-<60,60-<70,70-<80,80-<90,90-100μg/L.Within each stratum,one village was randomly selected,and 20 adults aged 20-60 years were sampled.A urine sample was collected for each participant to measure urinary iodine concentration,and thyroid nodules examination were performed.Results A total of 6214 urine samples were analyzed,reavealing a median urine iodine concentration of 257.0μg/L.Urine samples from Anyang,Nanyang,and Zhoukou Cities exhibited urinary iodine levels above 300μg/L,indicating excessive iodine intake.In contrast,samples from other regions showed basic adequate iodine levels.Out of 5877 adults screened for thyroid nodules,983 were diagnosed,yielding a detection rate of 16.7%.The median urinary iodine concentrations varied significantly across the water iodine starta(247.0,260.1,and269.6μg/L for strata of 40-<60,60-<80,and 80-100μg/L,respectively;H=11.885,P<0.05).However,the detection rates of thyroid nodules across stata did not show significant differences(18.4%,15.0%,and 16.4%,respectively,χ^(2)=4.471,P>0.05).Conclusions The iodine intake of adults in iodine adequate areas in Henan Province is in sufficient.It is recommended to strengthen monitoring in addition of ongoing prevention and control measures.Intervention measures should be adjusted dynamically in response to shifts in to changes of the population′s iodine nutrition status.
