Abstract
Mortality trends from 1950 to 1970 were studied for 473 cities in the United States with populations of 25,000 or more in 1950, according to fluoridation status of their water supplies. Findings showed no relationship between fluoridation and observed changes in general mortality over the 20-year period. Also, no relationship was found between fluoridation and heart or cancer death rate trends.
摘要
根据1950年人口在25000人及以上的美国473个城市的供水氟化状况，对这些城市1950年至1970年的死亡率趋势进行了研究。研究结果显示，在这20年期间，氟化与观察到的总体死亡率变化之间没有关系。此外，在氟化与心脏病或癌症死亡率趋势之间也没有发现关系。
