The relationship between consumption of chlorinated drinking water in the home water supply and serum lipids was examined in 2070 elderly White women. Private springs, cisterns, and wells were considered nonchlorinated and public water sources, chlorinated. Mean serum lipids and lipoproteins were similar in the chlorinated and nonchlorinated groups. Stratification by years of exposure revealed little difference in lipid concentrations. Lifestyle factors--for example, smoking and alcohol consumption--differed by years of exposure. Hence, previous reports of an association between chlorinated drinking water and serum cholesterol levels may reflect inadequate control of other factors differentially distributed across chlorinated exposure groups.
在2070名老年白人女性中，研究了家庭供水系统中氯化饮用水的消耗量与血脂之间的关系。私人泉水、蓄水池和水井被视为非氯化水源，公共水源则为氯化水源。氯化组和非氯化组的平均血脂和脂蛋白水平相似。按暴露年限分层显示，脂质浓度差异不大。生活方式因素，如吸烟和饮酒，因暴露年限而异。因此，先前关于氯化饮用水与血清胆固醇水平之间关联的报告可能反映出对不同氯化暴露组中其他因素分布差异的控制不足。
