Title: Disparities in Breast Cancer Screening Between Caucasian and Asian American Women

Country: United States

Age: Adult Only

Sex: Female

Population: Asian

Care Setting: Outpatient Ambulatory and Primary Care

Clinical Setting: Breast Cancer Screening

Data Level: National

Data Type: Government Survey

Data Source: National Health Interview Survey

Mitigation: No

Free Text Conclusion: Asians were less likely to have had a mammogram within the past 2 years after controlling for education, insurance, family income, marital status, and country of birth. There was no difference between Asians and non-Hispanic Whites in terms of the rate of follow-up diagnostic studies (ultrasound, MRI, and biopsy) after an abnormal mammogram, and the rates of cancer diagnoses were comparable between the two groups.

Abstract: INTRODUCTION: Asian American women have lower breast cancer incidence and mortality than their non-Hispanic White (NHW) counterparts. We sought to determine whether differences in screening practices could explain, in part, the variation in breast cancer detection rate. METHODS: The 2015 National Health Interview Survey, an annual survey that is representative of the civilian, noninstitutionalized American population, was used to determine whether mammography usage was different between Asian and NHW women. Women 40 y of age who identified as either Asian or NHW were included. RESULTS: A total of 7990 women 40 y of age (6.12% Asian, 93.88% NHW), representing 53,275,420 women in the population, were included in our cohort of interest; 71.49% of Asian and 74.46% of NHW women reported having had a mammogram within the past 2 y (P = 0.324). Controlling for education, insurance, family income, marital status, and whether they were born in the United States, Asians were less likely to have had a mammogram within the past 2 y than their NHW counterparts (odds ratio = 0.68; 95% confidence interval: 0.46-0.99, P = 0.047). Of patients who had an abnormal mammogram, there was no difference in the biopsy rate (20.35% versus 25.97%, P = 0.4935) nor in the rate of cancer diagnosis among those who had a biopsy (7.70% versus 12.86%, P = 0.211) between Asian and NHW women, respectively. CONCLUSIONS: Our findings suggest that the lower breast cancer incidence among the Asian population may, in part, be explained by a lower screening mammography rate in this population.
