Impact of U.S. Citizenship Status on Cancer Screening Among Immigrant Women

OBJECTIVES: We evaluated the relationship between U.S. citizenship status and the receipt of Pap smears and mammograms among immigrant women in California. DESIGN: Cross-sectional study using data from the 2001 California Health Interview Survey. PATIENTS/PARTICIPANTS: Noninstitutionalized, civilian women, aged 18 years and older living in California. MEASUREMENTS AND MAIN RESULTS: We analyzed data from the 2001 California Health Interview Survey and used logistic regression models to adjust for sociodemographic factors and for access and utilization of health services. After adjusting we found that U.S. citizen immigrants were significantly more likely to report receiving a Pap smear ever (adjusted prevalence ratio [aPR], 1.05; 95% confidence interval [CI], 1.01 to 1.08), a recent Pap smear (aPR, 1.07; 95% CI, 1.03 to 1.11), a mammogram ever (aPR, 1.17; 95% CI, 1.12 to 1.21), and a recent mammogram (aPR, 1.38; 95% CI, 1.26 to 1.49) as compared to immigrants who are not U.S. citizens. Also associated with receiving cancer screening were income, having a usual source of care, and having health insurance. Hispanic women were more likely to receive Pap smears as compared to whites and Asians. CONCLUSIONS: Not being a U.S. citizen is a barrier to receiving cervical and breast cancer screening. Additional research is needed to explore causal factors for differences in cancer screening rates between citizens and noncitizens

Disparities in Screening Mammography: Current Status, Interventions, and Implications

OBJECTIVE: This paper describes trends in screening mammography utilization over the past decade and assesses the remaining disparities in mammography use among medically underserved women. We also describe the barriers to mammography and report effective interventions to enhance utilization. DESIGN: We reviewed medline and other databases as well as relevant bibliographies. MAIN RESULTS: The United States has dramatically improved its use of screening mammography over the past decade, with increased rates observed in every demographic group. Disparities in screening mammography are decreasing among medically underserved populations but still persist among racial/ethnic minorities and low-income women. Additionally, uninsured women and those with no usual care have the lowest rates of reported mammogram use. However, despite apparent increases in mammogram utilization, there is growing evidence that limitations in the national survey databases lead to overestimations of mammogram use, particularly among low-income racial and ethnic minorities. CONCLUSIONS: The United States may be farther from its national goals of screening mammography, particularly among underserved women, than current data suggests. We should continue to support those interventions that increase mammography use among the medically underserved by addressing the barriers such as cost, language and acculturation limitations, deficits in knowledge and cultural beliefs, literacy and health system barriers such as insurance and having a source regular of medical care. Addressing disparities in the diagnostic and cancer treatment process should also be a priority in order to affect significant change in health outcomes among the underserved
