Health Care Access Among Asian American Subgroups: The Role of Residential Segregation.

Few studies have examined differences in health care access across Asian American ethnicities and none have considered the effects of residential segregation. The segregation of Asians by neighborhood has been steadily increasing over the past few decades due in part to the settlement patterns of immigrants. Data from the 2009 National Longitudinal Study of Adolescent Health (n = 746) were used. We examined differences in yearly medical checkups between Asian subgroups as well as among foreign-born and US-born Asians. Results showed that immigrant Filipinos and Vietnamese were less likely to get a checkup compared with foreign-born Chinese. The effect of Asian subgroup was modified by the percentage of Asians in a census tract (p < 0.01). Koreans and other Asians had a higher probability of getting a checkup when living in a predominately Asian neighborhood. For Chinese and Vietnamese residential concentration of Asians had a stronger inverse association with having a yearly checkup.

Neighborhood socio-economic disadvantage and race/ethnicity as predictors of breast cancer stage at diagnosis.

BACKGROUND: This study investigated the role of key individual- and community-level determinants to explore persisting racial/ethnic disparities in breast cancer stage at diagnosis in California during 1990 and 2000. METHODS: We examined socio-demographic determinants and changes in breast cancer stage at diagnosis in California during 1990 and 2000. In situ, local, regional, and distant diagnoses were examined by individual (age, race/ethnicity, and marital status) and community (income and education by zip code) characteristics. Community variables were constructed using the California Cancer Registry 1990-2000 and the 1990 and 2000 U.S. Census. RESULTS: From 1990 to 2000, there was an overall increase in the percent of in situ diagnoses and a significant decrease in regional and distant diagnoses. Among white and Asian/Pacific Islander women, a significant percent increase was observed for in situ diagnoses, and significant decreases in regional and distant diagnoses. Black women had a significant decrease in distant -stage diagnoses, and Hispanic women showed no significant changes in any diagnosis during this time period. The percent increase of in situ cases diagnosed between 1990 and 2000 was observed even among zip codes with low income and education levels. We also found a significant percent decrease in distant cases for the quartiles with the most poverty and least education. CONCLUSIONS: Hispanic women showed the least improvement in breast cancer stage at diagnosis from 1990 to 2000. Breast cancer screening and education programs that target under-served communities, such as the rapidly growing Hispanic population, are needed in California.

Comparison of extramural clinical rotation days: did the Pipeline program make a difference?

Extramural clinical rotations are implemented by dental schools for a combination of clinical and didactic or behavioral goals. In the United States, the Pipeline, Profession, and Practice: Community-Based Dental Education program was launched to increase the number of underrepresented minority students who are recruited and retained in dental education, to expand the dental curriculum in cultural competence, and to incorporate community-based extramural rotations into the dental schools' clinical curriculum. The objective of this study was to conduct an impact analysis regarding the change in number of extramural clinical rotation weeks for Pipeline and non-Pipeline program students over the time period of 2003 to 2007. National data from the American Dental Education Association's senior survey and other secondary sources were used to determine what student, school, and community characteristics are associated with a difference in the student report of the number of required weeks they expect to spend during their last year in dental school providing care at extramural clinic settings. Students reported a mean of 7.2 weeks for Pipeline students and 6.4 weeks for non-Pipeline students in 2003, increasing to 8.2 weeks for Pipeline students and 6.6 weeks for non-Pipeline students (p<0.05) in 2007. The multivariable model showed the Pipeline program increased significantly the number of rotational weeks reported by students. Three other variables significantly increased rotation weeks: 1) a lower baseline number of reported weeks in community rotations; 2) a lower level of debt student reported upon graduation; and 3) student reports of a higher orientation toward service to others as a reason to enter dentistry.

Who will serve? Assessing recruitment of underrepresented minority and low-income dental students to increase access to dental care.

This article uses data from the 2007 American Dental Education Association survey of dental school seniors to assess their intentions to serve underserved populations according to the students' underrepresented minority (URM) and income status. Dental school recruitment and retention programs that concentrate exclusively on URM students will not benefit most low-income students since 83 percent of them are not URM. Recruiting URM students leads to more graduating students with intentions to serve minorities. Whether the income of URM students was high or low, about half in each income group stated that more than 25 percent of their patients would be underserved minorities, compared to 28 percent of the low-income non-URM students and 17 percent of the higher income non-URM students. However, our multivariable results suggest that recruitment of both low-income groups (URM and non-URM) rather than high income regardless of ethnicity might be especially helpful in producing graduates who choose public service. URM/income status was not significantly related to serving special care or rural populations.

What enhances underrepresented minority recruitment to dental schools?

This study examined the factors influencing the proportion of underrepresented minority students (URM) in dental schools. Using a comprehensive recruitment model, it considered the relative importance of community characteristics (population demographics, oral health policies, dental care system, and university environment), dental school characteristics (Pipeline-supported, mission, and financing), and community-based dental education (CBDE) characteristics of the dental school on recruitment of URM students. Data come from a national survey of dental school seniors and a variety of publicly available sources. Three outcome variables measure URM recruitment: percent URM, percent Hispanic, and percent African American in the first year of dental school. Multivariable results revealed that the most important factors predicting a higher percent URM in first-year classes were a higher proportion of URM clinical faculty and graduating students' perceptions that their clinical rotation experience improved their ability to care for diverse groups. For percent Hispanic in the first year, a higher proportion of URM clinical faculty and students spending more time in clinical rotations predicted greater Hispanic recruitment. Graduating students' perceptions that they were less prepared to treat diverse groups were directly associated with the proportion of Hispanic students in the class. For a higher percent of African Americans in the first-year class, the most important factors were a higher proportion of blacks in the county, support from the national Pipeline program, and graduating students' perceptions of better preparedness to integrate cultural differences into treatment planning. Higher total financial aid awarded by the school was negatively associated with recruitment of African Americans. Results suggest some improved URM recruitment strategies for dental schools.

Effect of school environment on dental students' perceptions of cultural competency curricula and preparedness to care for diverse populations.

Reports of oral health disparities among racial, ethnic, and socioeconomic sectors of the U.S. population have hastened development of strategies to address this issue. Among these strategies is revising dental school curricula in order to develop more culturally competent graduates. The present study uses data from the 2003 American Dental Education Association (ADEA) survey of dental school seniors to assess students' perceptions of the adequacy of their cultural competency training. We hypothesize that these perceptions are influenced by multiple student characteristics and contextual factors, including a school's status with respect to the Pipeline, Professions, and Practice initiative of the Robert Wood Johnson Foundation and The California Endowment. Response data from ADEA survey items reflecting student perceptions of adequacy of curriculum time devoted to cultural competency and their preparedness to treat an ethnically and culturally diverse population were analyzed to assess the influence of selected student and contextual factors. Student gender, marital status, and level of educational debt were found to influence the curriculum time variable, and students at California schools reported higher perceived preparedness levels than students at dental schools nationwide. Dental school environments promoting acceptance and respect of diverse ethnicities/cultures and student race/ethnicity were significantly associated with students' perception of the adequacy of curriculum time for cultural competency and students' perception of their preparedness to provide oral health care for racially and culturally diverse groups. The findings provide insight for development of cultural competency curricula and direction for future study in this area.

What influences dental students to serve special care patients?

This study examines factors associated with graduating dental students' motivation to deliver services to special care patients. We investigated community context and student characteristics, which would influence potential behavior. Higher percentages of older adults and low-income residents in the community were positively correlated with interest in serving special care populations. Factors which correlated with individual student characteristics included having a father with at least a college education, a higher number of weeks spent in extramural clinical rotations, preparedness to provide care to disabled patients, and service orientation and socially conscious attitudes. Frail elderly and disabled persons have limited access to dental care, which is compounded by a shortage of skilled dental professionals who are willing to treat these populations. Our findings suggest that interest in special care dentistry is partly conditioned by the dental school's demographic and dental market context. This study is important to dental educators and policymakers because the challenge of providing care to the "special patient" will increase in the future.

Influence of contextual environment and community-based dental education on practice plans of graduating seniors.

This study investigated senior dental students' plans to provide care to underserved racial/ethnic minority populations. Three sets of determinants were analyzed: contextual environment, community-based dental education (CBDE), and student characteristics. We analyzed data from the ADEA Survey of Dental School Seniors and administrative data sources to construct contextual variables. Multivariable results show three contextual variables predicted practice plans: greater numbers of federally qualified health centers, higher percentages of underrepresented minorities, and attending a California Pipeline dental school. Regarding CBDE predictors, it was alarming to find seniors who viewed the cultural competency curriculum as inadequate and perceived themselves as less prepared to provide oral health care to diverse populations were also those most likely to serve minority patients. Significant student characteristics included racial/ethnic minority, female gender, older age, lower parent's income, and socially conscious orientation. The study provides evidence that contextual environment, CBDE, and student characteristics were significantly associated with plans to care for underserved patients. Findings suggest if the Pipeline initiative is successful in stimulating reform in U.S. dental schools, future students will develop greater awareness regarding critical access problems and the competencies required to effectively care for diverse populations. In the long term, addressing the problem of dental care access will require the creation of policy, financial, and structural interventions to motivate providers to care for the underserved.

Pipeline, profession, and practice program: evaluating change in dental education.

This article describes the conceptual and analytical framework that will be used to assess the effectiveness of the Pipeline, Profession, and Practice: Community-Based Dental Education Program. The evaluation will use a mixed method qualitative and quantitative data collection, analysis, and triangulation. Baseline measures are reported using data from the 2003 ADEA survey of dental school seniors. Baseline measures show the dental schools are confronting a major recruitment challenge that will require short and long pipeline efforts to attract and retain underrepresented and low-income (URM/LI) persons. Gaps were found between the perceptions of URM and non-URM students in the adequacy of the curricula. The majority of all seniors described the current extramural clinical rotations as positive experiences, but URMs were more likely to report the experience improved their ability to care for diverse groups.

Role of community risk factors and resources on breast carcinoma stage at diagnosis.

BACKGROUND: The current study investigated the individual and community determinants of breast carcinoma stage at diagnosis (BCSAD) using multiple data sources merged with cancer registry data. The literature review yielded 5 studies that analyzed cancer registry data merged with community-level variables (1995-2004). METHODS: Community variables constructed for the current study reflected social and economic risk factors, physician supply, and health maintenance organization penetration. Multivariate logistic regression was used to identify the significant predictors of increasingly progressive BCSAD. RESULTS: Disparities remained for black and Hispanic females in California, who were least likely to be diagnosed early compared with their white counterparts. Younger (< 40 years) and middle-aged (40-64 years) females were less likely to be diagnosed with early BCSAD, compared with older females (> or = 65 years). Utilizing services at hospitals serving a lower volume of patients with breast carcinoma was associated with later BCSAD. After controlling for individual-level factors, community-level variables constructed at the census block group and county level were tested. If a woman resided in a neighborhood with greater percentages of female-headed households, persons living below the poverty level, less educated people, and more recent immigrants, then her chances of being diagnosed at an earlier stage were diminished. If, conversely, she resided in a neighborhood with greater percentages of females > or = 65 years (a proxy for Medicare coverage), her access to medical care and the probability of earlier BCSAD increased. County-level insurance rates and residing in counties where greater percentages of women ever had a mammogram were associated with in situ and early-stage diagnosis. Similarly, the supply of primary care physicians and radiologists was associated positively with earlier BCSAD. CONCLUSIONS: Results confirmed community-level predictors of socioeconomic and delivery system context matter, although the individual-level predictors showed a stronger effect. Nevertheless, analysis of community variables is promising for guiding and evaluating the effects of health policy and developing community and delivery system interventions for earlier detection and treatment of breast carcinoma.
