| 目的 观察黑龙江省林区与非林区居民碘营养水平及相应甲状腺超声表现。方法 采用随机抽样方法，按男∶女1∶1抽取黑龙江省林区13个、非林区17个调研点3 645名居民，按年龄段分为A组（20~30岁）、B组（31~40岁）、C组（41~50岁）、D组（51~60岁）及E组（61~70岁），进行甲状腺超声检查及尿碘测定。结果 ①林区居民尿碘中位数低于非林区（P<0.05）；B、C、D及E组林区居民尿碘中位数均低于非林区（P均<0.05）；②随年龄增长，林区与非林区居民甲状腺结构异常率均呈增加趋势（P均<0.05）；林区居民甲状腺结构异常率高于与非林区居民（P<0.05），林区与非林区之间，甲状腺存在各种异常超声表现人数差异无统计学意义（P>0.05），D组与E组林区居民甲状腺结构异常率均高于非林区（P均<0.05）；③林区居民甲状腺异常者尿碘中位数低于非林区（P<0.05），D组及E组林区居民尿碘中位数均低于非林区居民（P均<0.05）。结论 随年龄增长，黑龙江省林区与非林区居民甲状腺结构异常率均增加，林区中老年人群甲状腺结构异常率高于、尿碘中位数低于非林区。林区与非林区20~29岁居民碘营养状态均处于超足量水平，其余各年龄段碘营养适宜，且林区居民尿碘含量均低于非林区。 |

| Objective To observe the iodine nutrition level and ultrasonic manifestations of thyroid in forest and non-forest land residents of Heilongjiang province. Methods Using random sampling method, 3 645 residents form 13 forests and 17 non-forests sites were selected and divided into 5 groups according to ages, i.e. group A (20-30 years), B (31-40 years), C (41-50 years), D (51-60 years) and E (61-70 years), and the ratio of male and female in each group was 1:1. Then all objects underwent thyroid ultrasound and urinary iodine. Results ①The median urinary iodine of forest residents was lower than non-forest residents (P<0.05). In group B, C, D and E, the median urinary iodine of forest residents were all lower than non-forest (all P<0.05). ②Along with the age growth, thyroid structure abnormal rate increased in both forest and non-forest residents (all P<0.05). The abnormal thyroid structure rate of forest residents was higher than that of non-forest residents (P<0.05). There was no statistical difference of the number of residents with abnormal ultrasonic manifestations between forest and non-forest residents (P>0.05). Thyroid structure abnormal rate of group D and E in forest residents were both higher than those in non-forest (both P<0.05). ③The urine iodine median in forest residents with ultrasonic abnormal thyroid was lower than in non-forest (P<0.05), while in forest residents in group D and E were both lower than non-forest (both P<0.05). Conclusion The rate of thyroid structure abnormality increased with aging in both forest and non-forest residents of Heilongjiang province, the thyroid structure abnormal rate in middle-aged and elderly forest residents was higher, whereas the urine iodine median was lower than non-forest. Iodine nutritional status were at adequate levels in forest and non-forest 20-29 years old residents, while at appropriate levels in all other ages. The urine iodine content in forest residents were lower than that in non-forest of the same ages. |
