摘要
定群观察了食盐加碘对地方性克汀病流行的影响。在我县低碘的三岔、土门两乡30个村38321人中,分别用食盐加碘和不加碘进行了10年定群研究观察,结果对照组与食盐加碘组人年发病率出现显著性差异(p<0.05),RR=5.89,AR％:83％。此后,两组皆食盐加碘观察6年,对照组人年发病率降至0.91/10万,两组的地方性克汀病流行均基本控制。
The effect of iodized table salt on the prevalence of endemic cretinism is studied among the same crowd of people. Observations have been made for 10 years among the 38 321 persons from the 2 townships of Sancha and Tumen who absorb low iodine. One group is with iodized table salt and the other one with table salt not iodized. As a result, between the incidences of the control group and the group with iodized table salt, there is significant difference (p<0.05), RR is 5.89 and AR% is 83%. After that, the two groups are observed for 6 years,being given iodized table salt. The incidence of the control group reduces to 0.91/100 000.The prevalence of endemic cretinism of the two groups can be controlled.
