Background: Understanding cancer screening behaviors is important for cancer prevention among Asian Americans.

Objective: To examine the association between acculturation and receiving cancer screenings within two years (colon, pap smear, mammography, and prostate) among Asian Americans.

Methods: We used data from 851 Chinese, Korean and Vietnamese Americans in Maryland. Acculturation was measured using an abridged version of the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA), acculturation clusters, language preference, length of stay in the U.S., and age at arrival. Age, education, income, ethnicity, and marital status were used as control variables. Health insurance and having a regular physician were included as mediators.

Results: Multiple logistic regression analysis showed that acculturation was positively associated with the likelihood of having all cancer screenings. Those lived for more than 20 years in the U.S. were about 2 times [odds ratio (OR) and 95% confidence interval (CI): colon cancer: 2.4 (1.5-4.0); pap smear: 2.1 (1.2-3.7); mammogram: 2.1 (1.2-3.7); prostate cancer: 3.3 (1.5-7.6)] more likely than those who lived for 10 years or less to have had cancer screening. Mediating effects of health insurance and having a regular physician were found between most cancer screening outcomes and length of stay and age at arrival. The association between length of stay and mammography was greatly reduced and became no longer significant after incorporating mediation of having a regular physician (OR=1.4 (0.8-2.6) compared to OR=2.1 (1.2-3.7)).

Conclusion: Acculturation is associated with cancer screening among Asian Americans. This association is mediated by health insurance and having a regular physician.
