目的了解蒙古族与汉族健康人群中甲状腺结节患病情况的差异。方法对进行健康查体的3544例(蒙古族828例,汉族2716例)既往无甲状腺疾病史的人员利用高频超声进行甲状腺检查并对结果进行统计分析。结果蒙古族828例,发现甲状腺结节342例,发病率41.30%;汉族2716例,发现结节1042例,发病率38.37%,蒙古族与汉族甲状腺结节发病率比较差异无统计学意义(P>0.05)。蒙古族男性460例,发现甲状腺结节174例,发病率37.83%;汉族男性1615例,发现甲状腺结节542例,发病率33.56%;蒙古族与汉族男性甲状腺结节发病率比较差异无统计学意义(P>0.05)。蒙古族女性368例,发现甲状腺结节168例,发病率45.65%;汉族女性1101例,发现甲状腺结节500例,发病率45.41%;蒙古族与汉族女性甲状腺结发病率比较差异无统计学意义(P>0.05)。结论呼伦贝尔地区蒙古族与汉族甲状腺结节总体发病率、男性间及女性间结节发病率无差异;蒙古族和汉族甲状腺结节发病率不论男女均随着年龄增长而呈增高趋势。
Objective To understand the prevalence of thyroid nodules among Mongolian and Han healthy people. Methods 3544 cases (828 cases of Mongolian nationality and 2716 cases of Han nationality) who had been in physical examination were examined by high-frequency ultrasonography for the past thyroid history and the results were statistically analyzed. Results There were 828 Mongolian patients with 342 thyroid nodules, the incidence rate was 41.30%. In Han nationality, there were 2716 cases with 1042 nodules, the incidence rate was 38.37%. There was no significant difference in the incidence of thyroid nodules between Mongolian and Han (P > 0.05). Among 460 Mongolian males, 174 cases of thyroid nodules were found, with a incidence rate of 37.83%. There were 1615 Han cases and 542 cases of thyroid nodules with a prevalence of 33.56%. There was no significant difference in the incidence of thyroid nodules between Mongolian and Han nationality Significance (P> 0.05). Mongolian women 368 cases, 168 cases of thyroid nodules were found, the incidence rate was 45.65%; 1101 cases of Han women, thyroid nodules were found in 500 cases, the incidence rate of 45.41%; Mongolian and Han women, the incidence of thyroid node was no significant difference (P> 0.05). Conclusion The overall morbidity of thyroid nodules between Mongolian and Han nationalities in Hulunbeir region is no different from that of male ones. The morbidity of thyroid nodules in Mongolian and Han nationality is increasing with age.
