对7个自然屯大骨节病家庭聚集性做了二项分布配合适度 X~2检验,结果看到,当 X 线患病率处于10%至90%时,均具有统计学上明显或非常明显的家庭聚集性倾向。家庭聚集性研究病因、传播途径及其防制对策,具有重要的流行病学意义。家庭聚集性表明同一家庭成员接触致病因素的机遇或条件相同。由于本文所选各自然屯分别饮用同一水源水,因此首先可以排除饮水作为病因载体的可能,其可能的原因和条件有待进一步研究。
The results of binomial distribution of familial aggregation of seven Kashin-Beck disease patients in seven natural villages showed that the prevalence of X-ray was statistically significant or significant when the prevalence of X-ray ranged from 10% to 90% Family aggregation tendency. Family aggregation research causes, transmission routes and prevention measures, has an important epidemiological significance. Family aggregation indicates the same opportunities or conditions for exposure of the same family member to the causative agent. Since the natural water sources selected in this paper are respectively used for the same source water, it is possible to exclude the possibility of drinking water as the carrier of etiology at first. The possible causes and conditions are for further study.
