    "Does this Look Infected to You?" Social Network Predictors of Dental Help-Seeking Among Mexican Immigrants
    (Springer Nature, 2018-04) Pullen, Erin; Perry, Brea L.; Maupome, Gerardo; Periodontology, School of Dentistry
    Compared to U.S. born Latinos, Mexican immigrants (MAs) have diminished health care access and face substantial barriers to accessing needed dental health services. However, little research has examined how MAs social networks shape their use of dental health services. Using data from 332 Mexican immigrants to the Midwest, this research examines the significance of individual and egocentric network characteristics on two measures of dental health service utilization. Findings reveal that network size, network dental service utilization, and the frequency with which MAs discuss acute problems with network ties, positively correspond to use of oral health services. Conversely, embeddedness in networks where ties hassle egos about dental issues and have low levels of dental health knowledge correspond to lower odds of using these services. This research is among the first to use ego network data and methods to examine the ways network characteristics shape oral health behaviors among this underserved population.

    Talking about Teeth: Egocentric Networks and Oral Health Outcomes in a Mexican American Immigrant Community
    (Emerald Publishing Limited, 2019) Pullen, Erin; Perry, Brea L.; Maupome, Gerardo
    Latinos in the United States have poor outcomes for periodontal and dental health. However, a detailed description of the mechanisms driving these patterns has only recently started to be addressed in the literature. In the current study, we explore relationships between individual-level characteristics of Mexican immigrants, properties of their networks, and experiences of dental problems. Specifically, using data from an urban community of Mexican immigrants to the American Midwest (n = 332), this study examines how characteristics of oral health matters (OHM) discussion networks and individual-level sociodemographic characteristics are associated with four adverse oral health outcomes. The results provide strong support for relationships between immigrants' network characteristics and dental problems. We find that people with more dental problems talk about these issues more frequently with network ties. Conversely, stronger relationships with OHM discussion networks, as measured by mean closeness, are predictive of fewer dental problems. In addition, we identify a link between perceptions of alters' knowledge about teeth, mouth, and gums and egos reporting better oral health outcomes. The observed patterns are suggestive of mechanisms of social influence that are well replicated in the social, medical, and public health literatures, but that have seldom been empirically tested in the domain of oral health. Though preliminary, our findings suggest a potential explanatory role for social networks in some of the most important questions and problems in oral health disparities research. In all, our findings suggest that social network members are active participants in the management and response to oral health problems in this immigrant group and should be considered an important factor in the development and course of diseases.
