To examine the incidence of cancer among Chinese immigrants in Alberta and compare these rates to those of Canadian-born Alberta residents as well as to the Chinese in China. Methods. Cancer cases among Chinese immigrants and Canadian-born Alberta residents were identified from the Alberta Cancer Registry (1974-1993). Statistics Canada provided population counts by age group, sex, and birthplace for Alberta residents for each of the census years (1971, 1981, 1986, and 1991). Direct age-standardized incidence rates (ASIRs) were calculated using the 'world population' as standard. ASIRs for Chinese in China were acquired from 'Cancer Incidence in Five Continents', Vol IV-VII. Descriptive analysis and Poisson regression modeling were employed to obtain the rate ratios for certain cancer sites among the three populations. Age-period-cohort analysis was used to examine the secular effect on cancer development of certain cancer sites. Results. Chinese immigrants had lower ASIRs for all cancer (excl. 173) than Canadian-born Alberta residents and Chinese in China for both males and females. Chinese immigrants had significantly higher ASIRs for liver, stomach, esophagus, and kidney cancers than the Canadian-born population but lower than Chinese in China. Chinese immigrants had significantly lower ASIRs for breast and prostate cancer than the Canadian-born population but higher than Chinese in China. Conclusions. First generation migrants' risk for overall cancer incidence was intermediate between that for Chinese in China and Canadian-born populations. There also appeared to be transition in risk towards the Canadian-born pattern for liver, colon, stomach. These findings are generally in line with those from other studies of this kind and extend the work on cancer mortality rates in Chinese migrants in Ontario by Hanley.221 p.Biology, Biostatistics.Thesis
