Abstract
BACKGROUND: As women with HIV live longer, the need for age-appropriate breast cancer screening will increase. We compared rates of screening mammography among women with and without HIV. METHODS: We used administrative health databases to identify all women in Ontario, Canada, who were eligible for screening mammography (aged 50 to 74 yr and no history of breast cancer) as of Apr. 1, 2011. We used multivariable log-binomial regression to compare the 2-year period prevalence of screening mammography in 2011 to 2013 among women with and without HIV and to examine the correlates of screening among women with HIV. RESULTS: We identified 1 447 015 screen-eligible women, among whom 623 (0.04%) were women with HIV. Women with HIV were less likely to undergo screening than women without HIV (50.1% v. 63.4%, p < 0.001). Following multivariable adjustment, HIV-positive status was associated with significantly lower odds of undergoing mammography (adjusted prevalence ratio [PR] 0.83, 95% confidence interval [CI] 0.77-0.89). Compared with women with HIV receiving regular care from both a family physician and an HIV specialist, women with HIV receiving neither kind of care (adjusted PR 0.64, 95% CI 0.50-0.83) or predominantly specialist care (adjusted PR 0.77; 95% CI 0.60 to 0.97) were less likely to undergo screening mammography. INTERPRETATION: Women with HIV are less likely to undergo breast cancer screening mammography than women without HIV. Addressing this disparity requires optimizing care delivery to ensure adequate provision of comprehensive primary care to people with HIV. Copyright 2017, Joule Inc. or its licensors.
