在沧州地区选30个村庄进行了甲状腺肿患病率的调查,对尿碘、血清T_3、T_4、TSH、甲状腺吸~(131)碘率和水、土壤、蔬菜及粮食中的含碘量进行了测定。结果表明,水碘含量最高的地区(350μg/L以上)多集中在靠近渤海湾的盐山、黄骅和海兴三个县。在这些地区,甲状腺肿患病率为4.39％(716/16324),10～15岁为发病高峰期,女性高于男性。统计学分析,水碘含量与甲状腺肿患病率及甲状腺肿大率呈明显的正相关(r_1=0.8969,r_2=0.7135)。
The prevalence of goiter in 30 villages in Cangzhou was surveyed and the iodine contents of urinary iodine, serum T_3, T_4, TSH, thyroid uptake of iodine (131) and iodine in water, soil, vegetables and grain were measured The determination. The results showed that the areas with the highest iodine content (over 350μg / L) were mostly concentrated in the three counties of Yanshan, Huanghua and Haixing close to the Bohai Bay. In these areas, the prevalence of goiter was 4.39% (716/16324), 10 to 15 years of age was the peak incidence, women than men. Statistical analysis, water iodine content and the prevalence of goiter and goiter rate was significantly positive (r_1 = 0.8969, r_2 = 0.7135).
