本文报告了乾安县平原类型大骨节病重病点次字井(深井改水实验点)和造字井(对照点)的流行病学特点,并提出了对病因载体的初步看法。两村都是历史发病点,从五十年代起,病情有加重。目前相当于相对活跃病区水平。发病年龄以4～14岁组为最高,30岁以后最少。性别无明显差异。次字井患病有家庭聚集性,造字井不明显。病户多系当地居住5年甚至15年以上的住户。发病的年度波动不明显,但有季节性波动,即春夏高于秋冬季。由于深井改水取得了较好的防病效果,结合本次调查研究,认为水和粮都可能是病因的载体。探讨病因时,应把注意力集中到当地原生自然地理环境,老户的生产特点和生活习惯。
This paper reports the epidemiological characteristics of the Kashin-Beck disease line in Qian’an plain (water diversion experiment point) and the well (reference point), and gives a preliminary view on the cause vector. Both villages are historical points of incidence, from the fifties onwards, the condition worsened. The current equivalent of relatively active ward level. The age of onset was the highest in the group of 4 to 14 years and the least after 30 years of age. No significant gender differences. Sick ill family aggregation, not well-known word. Sick families more than the local residents living 5 years or even 15 years of households. The incidence of annual fluctuations is not obvious, but seasonal fluctuations, that is, spring and summer is higher than the autumn and winter. As a result of deep well water improvement has made a good disease prevention effect, combined with the investigation, that water and food may be the carrier of the cause. When discussing the etiology, attention should be focused on the local natural and geographical environment, the production characteristics and living habits of the elderly.
