目的掌握广州市萝岗区居民食用盐碘含量水平,为巩固碘缺乏病防治效果采取科学干预策略提供依据。方法按照《碘缺乏病监测方案》和《2013年广东省医改地方病防治项目实施方案》的要求,采用分层随机抽样方法,将萝岗区按东、西、南、北、中划分为5个片区,在每个片区各抽取1个镇(街),每个镇(街)随机抽取4个村(居委),每个村(居委)随机抽检15户居民食用盐,用定性和定量方法进行碘含量检测。结果共采集300份居民食用盐样品,合格碘盐295份,不合格碘盐5份,非碘盐5份。碘盐覆盖率为98.3%,碘盐合格率为100.0%,合格碘盐食用率为98.3%,非碘盐率为1.7%,5个镇(街)合格碘盐食用率之间差异有统计学意义(χ2=20.39,P<0.05)。结论萝岗区居民合格碘盐食用率远远高于国家标准(>90%),碘缺乏病防治效果良好,但非碘盐问题仍然存在,应继续巩固碘缺乏病的防治成果。
Objective To understand the level of iodine in the salt of residents in Luogang District of Guangzhou City and to provide scientific basis for consolidating the prevention and treatment of iodine deficiency disorders. Methods According to the requirements of “Iodine Deficiency Disease Surveillance Program” and “2013 Guangdong Provincial Plan for Prevention and Treatment of Endemic Diseases”, a stratified random sampling method was adopted to divide Luogang District into 5 counties according to east, west, south, north and middle In each area, one town (street) is drawn from each area, and four villages (neighborhood committees) are randomly selected from each town (street). Each village (neighborhood committee) randomly selects 15 households’ salt for food use, and uses qualitative and quantitative Methods for iodine content detection. Results A total of 300 samples of resident salt were collected, 295 qualified iodized salt, 5 unqualified iodized salt and 5 non-iodized salt. The coverage of iodized salt was 98.3%, the qualified rate of iodized salt was 100.0%, the acceptable iodine salt consumption rate was 98.3% and the non-iodized salt rate was 1.7%. There was a statistically significant difference among the five towns (street) Significance (χ2 = 20.39, P <0.05). Conclusion The eating rate of qualified iodized salt of residents in Luogang District is much higher than the national standard (> 90%). The control effect of iodine deficiency disorders is good, but the problem of non-iodized salt still exists. The prevention and cure of iodine deficiency disorders should be continued.
