The purpose of this study was to examine the barriers that Mexican migrant women and their families encounter when accessing oral health services in North San Diego County, California. Data were collected from six focus groups with 52 participants; three focus groups were with community members, while the other three with Lideres (community health workers). The Behavioral Model for Vulnerable Populations (BMVP) provided the theoretical framework for this study. Ages of participants ranged from 18 to 81 years old, and the average age was 36. With the exception of 2 participants, all women had lived in the United States over 9 years. Data were collected for a larger study, Engaging Communities to Reduce Oral Health Disparities among Mexican Migrant families in North San Diego. Using these data, qualitative analyses were performed, specifically using data involving barriers to oral health care. The BMVP's predisposing, enabling, and need for care themes were utilized to present data findings. Based on study findings, an additional theme reflective of suggestions for an oral health community education program was included. The four themes were applied to both the community member and Lideres focus groups and separated accordingly throughout the results and discussion sections. The themes with the most findings were the predisposing and enabling themes, as they provided insight into the most challenging barriers that women encountered. The most prominent predisposing barriers were immigration status, US health care beliefs and language. Frequent enabling barriers included insurance coverage, cost and discrimination. Participants mentioned that education was the primary reason for their need for care. Suggestions for an oral health community education program included a binational focus. Findings support BMVP constructs that vulnerable populations face when seeking health care, yet suggests new themes that are specific to Mexican migrant women in North San Diego County. Study findings showed participants desire for health policy changes, including affordable coverage for immigrants and their families. Further, this study provided insight into how policy, health providers and community clinics can improve oral health service access to migrant populations.
