Title: Cancer screening among Native Americans in California.

Journal: Ethn Dis 21(2):202-9

Date: 2011 Spring

Abstract: OBJECTIVE: To determine the factors associated with cancer screening adherence among Native Americans living in California. PARTICIPANTS: 2,266 Native Americans identified from the California Health Interview Surveys during 2001, 2003, and 2005 eligible for cervical, breast, or colorectal cancer screening. METHODS: We fit multivariable logistic regression models to identify demographic and healthcare access predictors of adherence to cancer screening. RESULTS: The presence of a recent physician visit was significantly associated with cervical (odds ratio [OR] 7.34, 95% confidence interval [CI] 4.27, 12.6), breast (OR 3.29, 95% CI 2.0, 5.42), and colorectal (OR 3.02, 95% Cl 1.74, 5.23) cancer screening adherence. The report of a usual source of care was similarly positively associated with cervical, breast, and colorectal cancer screening adherence. Additional predictors for colorectal cancer screening included higher educational attainment (OR 1.56, 95% Cl 1.07, 2.28), and the presence of a comorbid condition (OR 1.54, 95% CI 1.16, 2.05). Experiencing discrimination (OR .42, 95% Cl .20, .89) and never being married (OR .49, 95% CI .27, .89) were negative predictors of breast cancer screening, while having insurance (OR 2.00, 95% CI 1.27, 3.15) was a positive predictor. Cervical cancer screening was positively associated with living at or above 300% of the federal poverty level (OR 2.69, 95% CI 1.50, 4.85). CONCLUSIONS: Regular access to health care and a physician are the most consistent predictors of cancer screening adherence among Native Americans and should represent a focus of activities to improve screening rates in these communities.
