目的通过定点连续监测,掌握大骨节病的流行特征,为大骨节病防治提供依据。方法按照全国大骨节病监测方案要求,对监测点7～12岁儿童100名进行临床检查及X线拍片,并进行发硒含量测定。结果麟游、临潼7～12岁儿童临床I度以上检出率由1990年8.57%、22.86%至1998、1994年分别降为0,榆阳区7～12岁儿童I度以上检出率由2000年0.87%至2001年降为0;麟游、临潼7～12岁儿童X线检出率由1990年44.76%、54.29%至1999年分别降为11.27%、6.67%,榆阳区7～12岁儿童X线检出率由2000年34.96%降至2008年的1.82%;麟游、临潼、榆阳区儿童发硒分别由0.0932μg/g、0.1667μg/g、0.1178μg/g上升到0.2911μg/g、0.2464μg/g、0.3700μg/g。结论儿童大骨节病病情呈稳定下降态势,达到国家大骨节病控制区标准。食用合格硒盐及非病区粮食,群众经济收入增加,生活、卫生水平提高是病情下降的主要原因。
Objective To monitor the prevalence of Kashin-Beck disease by continuous site-specific monitoring and provide the basis for the prevention and treatment of Kashin-Beck disease. Methods According to the requirements of the monitoring program of Kaschin - Beck disease in the country, 100 children from 7 to 12 years old in the monitoring area were examined with X - ray film and selenium content was measured. Results Linyou, Lintong 7 ~ 12-year-old children clinical I degree above the detection rate from 8.57% in 1990, 22.86% to 1998,1994, respectively, down to 0, Yuyang District, 7 to 12-year-old children I degrees above the detection rate from 2000 0.87% to 2001 dropped to 0; Linyou, Lintong 7 to 12-year-old children X-ray detection rate from 44.76% in 1990, 54.29% to 1999 were reduced to 11.27%, 6.67%, Yuyang District 7 ~ The detection rate of X-ray in 12-year-old children decreased from 34.96% in 2000 to 1.82% in 2008, while that in Linyou, Lintong and Yuyang districts increased from 0.0932μg / g, 0.1667μg / g and 0.1178μg / g respectively 0.2911 μg / g, 0.2464 μg / g, 0.3700 μg / g. Conclusion The prevalence of KBD in children shows a steady decline, reaching the standard of KBD control area in China. Consumption of qualified selenium salt and non-ward food, people’s economic income increased, life, improve the level of health is the main reason for the decline.
