摘要
目的了解奉化市居民碘营养状况,为制定和完善科学补碘策略提供依据。方法根据不同地理类型选取3个村(居委会)841名居民作为调查对象,共采集841份尿样、300份盐样和16份水样分别进行尿碘、盐碘和水碘浓度检测,并对大于等于6周岁的调查对象开展甲状腺B超检查。结果盐碘和尿碘浓度中位数分别为28.45mg/kg和171.26μg/L,不同地区人群尿碘水平差异有统计学意义(χ2=57.972,P=0.000),经常食用海产品的人群尿碘水平高于不经常食用海产品的人群(Z=-2.595,P=0.009)。结论奉化市属于环境碘缺乏地区,居民碘营养水平总体上处于较适宜水平,但山区居民尿碘水平处于超过适宜量。
Objective To understand the iodine status of residents in Fenghua and provide references for developing and improving scientific strategy of iodine supplementation.Methods 841 local permanent residents in 3 villages（communities） were sampled depending on the type of geography.841 urine samples,300 iodized salt samples and 16 water samples were tested respectively to measure their concentrations.Objects older than and equal to 6 years underwent the thyroid B ultrasonic examination.Results The median level of salt iodine and urinary iodine were 28.45 mg/kg and 171.26 μg/L,respectively.Urinary iodine among different area population was significant difference（χ2=57.972,P=0.000） and urinary iodine among population who regularly consumed seafood was higher than who did not regularly consume seafood.Conclusions Fenghua appeared to be an area where the environment was iodine deficient.The iodine status among the general population seemed to be safe and suitable,but median level of the urinary iodine among mountain area population was higher than 200 μg/L.
