2003,2004年甘肃省大骨节病监测结果分析

Analysis of Surveillance Results of Keschin-Beck Disease in Gansu Province in 2003 and 2004

目的掌握大骨节病病情动态,为防治研究提供资料。方法对38个监测点7～12岁儿童进行临床检查及拍右手X线片;各监测县每季度检测盐硒含量;隔年检测儿童发硒。结果2003,2004年临床检查7～12岁儿童数分别为3678人和4031人,I°以上检出率分别为1.09%,1.19%;拍X线手片分别为2162张和2205张,总检出率分别为8.33%和7.48%;检测硒盐577份和856份,硒盐合格率分别为80.95%与98.00%。2004年检测33个点儿童发硒246份,硒含量在0.117～0.38μg/g。结论甘肃省儿童临床患病率和X线检出率呈下降趋势,但局部病区病情仍有波动。加强补硒措施是控制大骨节病的重要手段。

Objective To master the prevalence state of Keschin - Beck disease （ KBD）, and provide academic data for prevention and treatment. Methods Clinical examination and plain X - ray of right hand were carried out in children of 7 - 12 years old in 38 monitoring sites. Selenium levels in salt were tested per month and hair selenium of children was also detected every two years. Results In 2003 and 2004, 3 678 and 4 031 children aged 7 - 12 were taken clinical examination with the positive rate over I° of 1.09% and 1.19% respectively; fight hand positive rate of X -ray of 8.33% and 7.48%. 577 and 856 salt samples were examined, with the detection rate of 80.95% and 98% respectively in 2003 and 2004. Hair selenium levels of 246 samples at 33 sites were between 0. 117 μg/g and 0.38 μg/g in 2004. Conclusions The KBD preva- lence state generally declined in Gansu Province in 2003 and 2004, but the prevalence rate has a tendency of fluctuation yearly in some sites. It is important measure for controlling KBD to ensure selenium salt supplement.
