Disparities in mammography rates have been documented for underserved populations, yet no data are available for women with mental illness in primary care settings. We analyzed data on mammography rates for 526 women age 40-70 who were new patients and completed the Primary Care Evaluation of Mental Disorders (PRIME-MD). There were no significant differences in mammography rates among women who screened negative and positive for any mental illness (56% and 53%, respectively). Screening for mental disorders in primary care does not appear to identify women at risk for nonreceipt of mammography.
