Estimated age-adjusted incidence rates for cancer during 1971--77 among Kaiser Foundation Health Plan (KFHP) members living in a portion of the San Francisco Bay area (SFBA) characterized by a heavy concentration of petroleum and chemical industries were compared to estimated rates among KFHP members in the remainder of the SFBA. One hundred fifty-four comparisons were done for 41 selected cancer sites. The number of significant differences did not appear inconsistent with what might be expected by chance alone; furthermore, in most of these instances the so-called exposed area showed the lower rate. These findings provided some assurance that place of residence near petrochemical industries is not associated with increased cancer risk.
1971年至1977年期间，对居住在旧金山湾区（SFBA）一部分、以石油和化学工业高度集中为特征的凯撒基金会健康计划（KFHP）成员的癌症年龄调整发病率估计值，与SFBA其余地区KFHP成员的估计发病率进行了比较。对41个选定的癌症部位进行了154次比较。显著差异的数量似乎与仅由偶然因素预期的情况并无不一致；此外，在大多数这些情况下，所谓的暴露地区显示出较低的发病率。这些发现为居住在石化工业附近与癌症风险增加无关提供了一些保证。
