摘要
本文从流行病学角度着手研究了永寿县大骨节病30～90年代初患病情况,结果表明病情在70年代处于高峰,80年代逐年大幅度下降。1990年4月调查患病总人数比1981年明显减少,临床患病率已由26.9％降至1.4％,X线阳性率由44.3％降至3.7％,活跃指数由50.4降至4.3,下降程度比国家病情基本控制标准要求还低。分析认为:以硒为主的综合防治措施对全县病情下降起了主导作用。主食小麦增多、副食条件改善、施用磷肥、脱贫致富等社会因素显著变化对控制病情有重要意义。
Retrospective studies of Kaschin-Beck disease prevalence in Yongshou County, Shaanxi Province from 30s to 90s were carried out. Results showed that the prevalence reached a peak in 70s, however it decreased apparently year by year in 80s. Our study also indicated that total number of patients in 1990 was far less than that in 1981. Meanwhile clincal prevalence rate uecreased from 26.9% down to 1.4%, X-ray positive rate from 44.3% down to 3.7% and active index of the disease from 50.4 down to 4.3, when above mentioned indices in 1981 were compared with those in 1990. It was worth noting that decreased levels of these indices were even lower than those of national primary control standard for the disease. By analyzing our data, we thought that comprehensive method in which selenium was a main factor played a key role in the prevalence decrease of the disease. In addition, more proportion of wheat consumption, diversified foods, use of phosphate fertilizer and the improvement of living condition of endemic population were also responsibe for the prevalence decrease.
