The purpose of this study was to assess mammography utilization among Korean-American women and to identify their knowledge, attitudes and barriers related to screening. Face-to-face interviews were conducted in the Korean language with a convenience sample of 229 predominantly low-income Korean women 50 years and older residing in Los Angeles. Forty-nine percent had ever had a mammogram, 24% had had a screening mammogram in the past 12 months, and 36% had had one in the past two years. Variables positively related to "ever had a screening mammogram" included: having health insurance; income > or = $25,000; having received a physician's recommendation to obtain a mammogram; holding positive group norms; longer duration of residency in the U.S.; and greater acculturation. Variables negatively related to screening included: concerns about finding cancer; taking time to get a mammogram; transportation; embarrassment; and discomfort requesting the procedure from the physician. Strategies to increase mammography utilization among Korean-American women are discussed.
