The primary purpose of this study was to assess whether Sydney, Industrial Cape Breton County excluding Sydney (ICBxS) and Cape Breton County (CBCo) residents were at increased risk for cancer compared to Nova Scotia (NS) residents over five-year periods during 1979 through 1997. Gender-stratified, age-standardized cancer incidence rates were calculated following the direct method. All-cause rates were higher for female and male residents of Sydney, ICBxS and CBCo compared to NS based upon both municipality and postal code methods of residence classification. A sensitivity analysis of residential coding yielded a high degree of consistency for all geographies except Sydney, limiting comparisons of Sydney rates with other local geographies except where consistencies were observed. The results of this ecological study support the need for further analysis of factors contributing to the increased risk for cancer in CBCo.
本研究的主要目的是评估在1979年至1997年的五年期间，悉尼、不包括悉尼的布雷顿角岛工业区县（ICBxS）和布雷顿角县（CBCo）的居民与新斯科舍省（NS）居民相比，患癌风险是否增加。采用直接法计算了按性别分层、年龄标准化的癌症发病率。根据市政和邮政编码两种居住地分类方法，悉尼、ICBxS和CBCo的女性和男性居民的全因死亡率均高于NS。除悉尼外，对居住地编码的敏感性分析在所有地区都产生了高度一致性，这限制了悉尼与其他当地地区的发病率比较，除非观察到一致性。这项生态学研究的结果支持进一步分析导致CBCo患癌风险增加的因素。
