燃煤污染型地方性氟中毒流行病学的初步研究

A preliminary study on the epidemiology of coal-pollution-burned endemic fluorosis in jianshih County,Hubei province

本文对八个生产组居民平均烧煤时间和烧煤数量与16岁以上当地居民的氟骨症患病率进行了相关与回归分析。结果表明:烧煤时间与氟骨症患病率呈明显相关关系,r=0.955,p<0.0005,Y=1.0811X-7.8109,全年烧煤数量与氟骨症患病率之间也呈明显相关关系(r=0.881)。此外,本文还结合相关与回归分析结果,讨论了烧煤时间和烧煤数量对氟骨症患病率的影响及根据烧煤时间的调查来估算氟骨症的患病率。

A correlation and regression analysis of the average time and amount ofburning coal in the eight groups and the prevalence rate of osteofluorosis of localinhabitants above the age of 16 was carried out The results showedthat there was a positive correlation between the time of burning coal and theprevalence rate of osteofluorosis.The correlation coefficient was 0.955(P<0.0005),its regression equation:Y=1.0811x-7.8109;there wcs also a positivecorrelation between the amount of burning coal of all the year round and theprevalence rate of osteofluorosis(r=0.881).In addition,in the light of theabove results,this paper dealed with effects of the time and amount of burningcoal on the prevalence rate of osteofluorosis and the method of calculating theprevalence rate of osteofluorosis according to the time of burning coal.
