[Analysis of urine screening results for school-age children in Zhucheng City of Shandong Province of China in 2013].

Objective: To study the significance of urine screening for school-age children by analyzing urine screening results of school-age children from Zhucheng City, Shandong Province, China, in 2013.

Methods: A total of 37 344 school-age children were randomly selected from children 6 to 12 years of age in Zhucheng City. Morning urine was tested by routine screening test, and the children who tested positive were re-tested after two weeks.

Results: There were 2 388 children (6.39%) tested positive in the first screening, and 388 children (1.04%) tested positive again in the second screening. The positive rates in the first and second screening tests were 9.52% and 2.01%, respectively, in girls, which were significantly higher than those in boys (3.79% and 0.23%, respectively; P<0.05). Among the children who had positive test results in the second screening, 302 (0.81%) were diagnosed with urinary system diseases.

Conclusions: Urine screening is an effective way for the early detection of some occult kidney diseases, which provides great benefits for early prevention and treatment of kidney diseases in children.
