【摘要】：目的 通过调查掌握浙江省居民碘营养水平状况,对居民家庭盐碘、水碘及居民尿碘进行检测,分析评估浙江省居民碘营养水平及相关的影响因素,为合理制定居民碘营养干预措施提供科学依据,进一步保障浙江省居民身体健康。 方法 按分层整群随机抽样法,抽取浙江省9个市22个县区居民,进行流行病学问卷调查及盐碘、水碘、尿碘检测。应用SPSS17.0软件包进行统计分析,采用描述性统计方法分析浙江省居民碘营养水平,采用单因素分析采用参数t检验和非参数Z检验(计量资料)或χ2检验(计数资料)及多因素Logistic逐步回归模型分析尿碘水平影响因素。 结果 共调查采集盐样7811份,水样品265份,共对19517人进行尿碘检测,其中男性8017人,女性11018人,哺乳期妇女172人,妊娠期妇女229人。 浙江省居民家庭食用盐盐碘中位数为28.80mg/kg,全省碘盐覆盖率为79.54%,合格碘盐食用率为76.65%；浙江省居民饮用水水碘中位数为2.42μg/L,87.92%的调查地区水碘低于10μg/L;浙江省居民尿碘中位数为160.74μg/L,100μg/L者占25.92%,=300μg/L者占15.30%。各年龄段人群尿碘中位数均处于(100-199)μg/L的适宜范围内,我省人群碘营养水平还是处于适宜水平的。 家庭食用盐碘浓度低于20mg/kg人群尿碘中位数为116.20,ug/L,(20-50)mg/kg人群为174.00μg/L,而大于50mg/kg人群尿碘中位数达到了206.19μg/L,三者间差异有统计学意义(x2=506.93,P0.05),提示随着盐碘浓度的升高,尿碘水平也随之升高。而水碘浓度小于10ug/L地区人群尿碘中位数为163.40μg/L,与水碘浓度大于10μg/L地区的169.00μg/L差别不大(Z=0.09,P0.05)。尿碘浓度随着年龄的增加而降低,文化程度越高人群尿碘浓度越低,常吃腌制食品人群尿碘浓度较高,年龄、文化程度以及饮食习惯也是尿碘含量的相关因素。 结论 浙江省居民碘营养水平总体处于适宜水平,不存在碘过量问题；居民家庭食用盐盐碘中位数浓度与我国现行的合格碘盐浓度相近；我省不存在水碘过高现象,其中大部分地区水碘含量都较低。
[Abstract]:Objective to investigate the status of iodine nutrition in residents of Zhejiang Province, to detect the iodine in salt, water and urine, and to analyze and evaluate the iodine nutrition level of residents in Zhejiang Province and its related influencing factors. To provide scientific basis for rational formulation of iodine nutrition intervention measures and to further protect the health of residents in Zhejiang Province. Methods according to stratified cluster random sampling, the residents of 22 counties in 9 cities of Zhejiang province were selected and tested with epidemiological questionnaire and salt iodine, water iodine and urine iodine. SPSS17.0 software package was used for statistical analysis and descriptive statistical method was used to analyze the iodine nutrition level of residents in Zhejiang Province. Single factor analysis was used to analyze the influencing factors of urinary iodine level by using parameter t test, nonparametric Z test or 蠂 2 test (count data) and multivariate Logistic stepwise regression model. Results A total of 7811 salt samples and 265 water samples were collected. A total of 19517 people were tested for urinary iodine. Among them, 8017 were male, 11018 were female, 172 were lactating women and 229 were pregnant women. The median of salt iodine was 28.80 mg / kg, the coverage rate of iodized salt was 79.54 and the consumption rate of qualified iodized salt was 76.65 mg / kg. The median of iodine in drinking water in Zhejiang Province was 2.42 渭 g / L ~ (-1) 87.92%, and in Zhejiang Province, the median of urine iodine was 160.74 渭 g / L ~ (100 渭 g / L) and 25.92 渭 g / L ~ (300 渭 g / L), 15.30%, respectively. The median of urinary iodine in all age groups was in the range of (100-199) 渭 g / L, and the level of iodine nutrition was still in the appropriate level. The concentration of salt iodine in family was lower than that in 20mg/kg group (116.20 渭 g / L), (20-50) in mg/kg group was 174.00 渭 g / L, but higher than that in 50mg/kg group (206.19 渭 g / L). The difference among the three groups was statistically significant (x20.506.93), which suggested that the level of urinary iodine increased with the increase of salt iodine concentration. However, the median of urinary iodine in 10ug/L was 163.40 渭 g / L, which was not different from that in 169.00 渭 g / L of water over 10 渭 g / L (P 0.05). The urinary iodine concentration decreased with the increase of age, the higher the education level, the lower the urinary iodine concentration, the higher the urinary iodine concentration was in the people who often ate pickled food. Age, education level and dietary habits were also the related factors of urinary iodine content. Conclusion the iodine nutrition level of residents in Zhejiang Province is generally at the appropriate level, and there is no problem of iodine excess, the median iodine concentration of salt in residents is close to the current qualified iodized salt concentration in China, and there is no phenomenon of excessive iodine in water in our province. In most of these areas, the iodine content in water is low.
