污灌区居民健康状况的调查研究

Investigation on the Health Among the Residents in the Sewage irrigated Area

为观察污灌区居民健康状况，抽样调查了一个自然村内长住５年以上居民１８４５人（男９０９人，女９３６人）。结果表明血液、唾液与尿液免疫球蛋白均低于非污灌对照区居民（Ｐ＜０．０１）。污灌区居民询问调查的患病率（４．５５３％）高于对照区居民（３．５２４％），Ｐ＜０．０１。污灌区居民年标化发病率（２．３６３％）、癌标化发病率（０．２１７％）高于对照区居民（分别为２．０９３％与０．１２１％）。污灌区居民年标化死亡率（０．６７２％）、标化癌症死亡率（０．１６３％）高于对照区居民（分别为０．５５１％与０．０６６％）。上述污灌区与对照区之间各率的统计学差异非常明显。

residents (male 909,female 936) who had been in a natural village for five years were collected with a cluster sampling for the investigation,of which the aim was to observe the human health in the area irrigated with sewage The results showed that:the levels of immunoglobulins (IgA,IgG and IgM) in the serum,saliva and urine among the residents in sewage irrigated area (SIA) were lower than those of the control in non sewage irrigated area(NSIA) respectively( P<0 01 ) The prevalence rate (4 553%) in SIA was higher than that (3 524%) in NSIA( P<0 01 ) In SIA,the annual standardized incidence rate (2 363%),SIR of cancer (0 217%),annual SMR(0 672%) and SMR of cancer (0 163%) were higher than those (2 093%,0 121%,0 551%,0 066%) of the controls All the health indexes mentioned above presented significant statistical differences between the residents in the SIA and NSIA
