儿童与成年人甲状腺结节患病率对比研究
A comparative study of prevalence of thyroid nodules in children with that in adults
按人口容量比例抽样法(PPS),以某中心小学为调查点,以某村20~ 80岁居民为成人对照,采用横断面调查方法,B超检查儿童甲状腺容积与结节,砷铈催化分光光度测定方法检测尿碘,直接滴定法测定盐碘含量.共调查6~12岁儿童180人,甲状腺肿大2例,肿大率1.11%,发现甲状腺结节16例,患病率8.89%,男生3例,患病率3.45% (n=87),女生13例,患病率13.98% (n=93),女生患病率大于男生(x2=6.154,P=0.015).该村儿童期患病率低,成人甲状腺结节患病率24.51%,2组差异有统计学意义(x2=17.368,P=0.001),且随年龄增长,甲状腺结节患病率逐渐增高.
更多[Summary] With populational proportional sampling (PPS) method in Baiguo village,one central primary sehool was selected,and villagers aged 20-80 in nearly village were chosen as control.Cross-seetional survey methodology was employed,B-type ultrasonography was used to determine thyroid volume and nodule of ebildren.Arsenic cerium catalytic spectrophotonetric assay was employed to detect urinary iodine.A direct titration measurement was used to determinate iodine content in salt.180 children aged 6-12 were surveyed,2 cases of goiter were found (1.11%).16 cases of thyroid nodules were discovered(8.89%),including 3 boys(3.45%,n =87) and 13 girls(13.98%,n =93).Girls had a higher prevalence than boys (x2 =6.154,P =0.015).The prevalence of thyroid nodules in that village was 24.51%,being statistically significant between 2 groups (x2 =17.368,P =0.001),and increasing with the age.
