本文对河南省地甲病流行地区不同劳动强度7—14岁健康青少年24小时尿肌酐排泄量进行了测定和分析。从1440份样品测定结果表明:7—14岁男、女各年龄组24小时尿肌酐排泄量为山区明显高于丘陵和平原(P>0.05);24小时尿肌酐排泄量随年龄、体重的增大而增多,相关分析均呈高度正相关,P<0.001,有非常显著性意义;在两性之间各年龄组肌酐均值均为男>女;7—12岁男、女24小时尿肌酐均值均低于成人,13—14岁男、女均值接近成人。因而我们建议:对7—14岁人群使用午后一次随机尿样在换算24小时总尿碘量时,肌酐系数应采用不同地形、不同性别、年龄的相应肌酐系数,13—14岁男、女青少年也可采用成人肌酐系数。
In this paper, endemic endemic to endemic areas of Henan Province, different labor intensity of 7-14 healthy adolescents with 24-hour urinary creatinine excretion was measured and analyzed. The results of 1440 samples showed that urinary creatinine excretion in 24 hours in each age group was significantly higher than that in hills and plains in mountainous areas (P> 0.05). Urinary creatinine excretion increased with age and body weight Large and increased, the correlation analysis showed a high degree of positive correlation, P <0.001, a very significant significance; in all age groups between the average creatinine were male> female; 7-12 years of age, male and female 24-hour urinary creatinine average Below adult, 13-14 year old male, the mean value is close to adult. Therefore, we suggest that the creatinine coefficient should be calculated according to different topography, gender and age, the corresponding creatinine coefficient, and the male and female adolescents aged 13 to 14 Adult creatinine coefficients can also be used.
