Background: Historically, all black persons, regardless of ancestry or country of origin, have been categorized as one group for cancer research and control efforts. This practice likely masks variability in exposure to determinants of disease, as well as in risk of cancer incidence and mortality. The current study examines potential differences in knowledge of human papilloma virus (HPV) between Haitian women living in Little Haiti, Miami, Florida, and a national sample of predominately African American women.Methods: Data for Haitian women were collected in 2007 as part of an ongoing community-based participatory research initiative in Little Haiti. For purposes of comparison, we used data from a largely African American subsample of the 2007 Health Information National Trends Survey (HINTS). These data sources used identical items to assess HPV knowledge, providing a unique opportunity to examine how this outcome may vary between two very distinct populations who are often grouped together for research and disease surveillance.Results: Relative to the HINTS sample, Haitian women were far less likely to have heard about HPV. Conclusions: Study data highlight important differences in Haitian and African American women's knowledge of HPV, a known determinant of cervical cancer risk. Such findings suggest that continuing to classify persons of similar phenotype but different cultural backgrounds and lifetime exposures as one group may preclude opportunity to understand, as well as attenuate, health disparity.

When compared to other racial/ethnic minorities and immigrants in Miami, Florida, Haitian women are more likely to be diagnosed with late-stage breast cancer when the prognosis for survival is poor. This disparity likely reflects mammography underutilization. Previous research has not examined the frequency of mammography use among Haitian women in Miami. Our study addresses this gap. In 2007, Community Health Workers (CHWs) recruited nearly 1,000 Haitian women from community venues across Little Haiti, the predominantly Haitian area in Miami, to participate in Rapid Assessment Surveys (RAS). RAS are a quick, cost-efficient method for assessing the prevalence of health behaviors in communities with high-rates of illiteracy and/or distrust of research. Our data indicate Haitian women are less likely than other women in Florida to report regular mammography. Such findings, though not surprising, suggest that grouping all black persons, regardless of ancestry, into one research category may mask variation in disease risk.
