本文运用环境流行病学的调查方法,以75年—84年的十年罹患率为指标,分析了商丘地区尿石症发病与饮水水质中总硬度、永久硬度、钙、镁等因素的关系。结果,饮用水的永久硬度高(平均值19.72度),人群发病水平高(标化罹患率241/10万);饮用水的永久硬度低(平均值7.62度),人群发病水平低(标化罹患率89/10万)。经卡方检验(p<0.05)差异显著。R·R=2.71。饮水水质中其它因素与尿石症的关系均无显著性意义。
In this paper, the environmental epidemiological survey method, taking 75 years of 84 years of the 10-year attack rate as an indicator, the Shangqiu area urolithiasis analysis and total water hardness, permanent hardness, calcium, magnesium and other factors. As a result, drinking water had a high permanent hardness (average 19.72 degrees) and a high prevalence in the population (normalized incidence of 241/10 million); low permanent hardness of drinking water (average 7.62 degrees), low incidence in the population Attack rate 89/10 million). The chi-square test (p <0.05) significant difference. R · R = 2.71. Other factors in drinking water quality and urolithiasis no significant significance.
