6. OMB Directive No. 15 Separate questions used for reporting race and ethnicity
Ethnicity (1st)- cultural identity
-- Hispanic or Latino
-- Not Hispanic or Latino
Race- physical characteristics/ geographic origin
-- American Indian or Alaska Native
-- Asian
-- Black or African American
-- Native Hawaiian or Other Pacific Islander
-- White
Respondents have the option of selecting one or more racial designations.
Reporting: Except when the collection involves a sample of such size that the data on the smaller categories would be unreliable, or when the collection effort focuses on a specific racial or ethnic group.
7. Combined format
Six minimum categories:
-- American Indian or Alaska Native
-- Asian
-- Black or African American
-- Hispanic or Latino
-- Native Hawaiian or Other Pacific Islander
-- White
Never use whites vs nonwhites
8. Definitions White. A person having origins in any of the original peoples of Europe, the Middle East, or North Africa
Black or African American. A person having origins in any of the black racial groups of Africa. Terms such as "Haitian" or "Negro" can be used in addition to "Black or African American."
West Indian, African
American Indian or Alaska Native. A person having origins in any of the original peoples of North and South America (including Central America), and who maintains tribal affiliation or community attachment.
-- Native Hawaiian or Other Pacific Islander. A person having origins in any of the original peoples of Hawaii, Guam, Samoa, or other Pacific Islands.
-- Asian. A person having origins in any of the original peoples of the Far East, Southeast Asia, or the Indian subcontinent including, for example, Cambodia, China, India, Japan, Korea, Malaysia, Pakistan, the Philippine Islands, Thailand, and Vietnam.
-- Hispanic or Latino. A person of Cuban, Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race. The term, "Spanish origin," can be used in addition to "Hispanic or Latino."
9. Olveen comment: never compare across races!!!
use a referent usually NHWS
Not chi square across groups
It is Hisp vs NHWs and Blacks vs NHWs
Can do Hisp vs Blacks if part of hypothesis

22 million age 55+ (18% pop)
13 million age 65+ (13% pop)
18. Birth rate: United States, 2000
20. Genetics Specific differences in genes are still under study
In the case of diabetes in Mexican-Americans, genetic admixture seems to have a clear role
American indigenous people have very high prevalences of diabetes compared to Whites
There is a paucity of data regarding genetic differences among Latino subgroups
22. Studying genetics in AAs Can trace certain ancestral alleles to Central Africa
Can follow single gene mutations that are Mendelian
Not very meaningful in genetically complex disorders
Hypertension in AAs
Htn in Africa ? Gene environment intercation
K channel
Related to higher salt diet
23. Why study Genetics in Latinos There is no Latino gene!!!!!!
Latinos as a genetic group not cw evolution
Latinos very genetically homogeneous
PRs very different from Mexicans
Mexican Spaniards very diff from Mayans
Good model of genetics overall
Large families
Close connections
Higher disease burden: Diabetes, Alzheimer’s
Can study gene environment interactions
Barrios
Native countries
25. More on DM Pima Indians in Mexico vs US Pimas
Why are poor whites genetically at risk for diabetes versus rich whites
26. What are disparities Differences in the health of racial or ethnic minorities versus non Hispanic whites
not due to known reasons such as income, location etc?
Differences in quality of health care received by racial or ethnic minorities versus non Hispanic whites
Not due to clinical needs or preferences ?
Not due to known reasons such as income ?
27. Why are disparities important? While great gains have occurred in improving overall health and reducing health disparities, the persistence of racial, ethnic, economic, or other social inequalities in health is unacceptable.

47. Latino paradox Many studies link poverty to poor health
Latinos are poorer than African Americans but have lower overall mortality rates, death from cancer and heart disease, infant mortality than AAs/ whites
But--acculturation leads to poorer health outcomes
48. Latino paradox What causes the paradox? Theories:
“Healthy immigrant”; “salmon” hypotheses
Strong social/family networks
Low tobacco and ETOH use especially in women
Religiosity
Traditional healing practices
Traditional diet

53. Forty-Four Million Uninsured
In 1998, 44 million Americans were uninsured, more than at any time since the passage of Medicare and Medicaid in the mid 1960's. While 44 million were uninsured at any one time during the year, about 55 million people lacked coverage for at least one month. Over the course of 28 months more than 67 million are uninsured for at least one month. Hence, about one quarter of the population has experienced a recent bout of "uninsurance.“
The situation is particularly bad for young people. About 11.1 million (15.0%) children under 18 are uninsured at any one time. Among young adults age 18-24, 30.1% are uninsured. During 1995-1996 23.1 million of the total of 70.8 million children in the U.S. went without health insurance for at least one month.
Poorer families have the highest uninsurance rates, but even the well-to-do are at risk. 25.2% of persons in households with annual incomes below $25,000 were uninsured in 1998, vs. 8.3% of those with household incomes greater than $75,000.
People with serious illnesses or disabilities depend predominantly on public programs. While 46% of health costs for persons without disability are paid by private insurance, private insurance accounts for only 27% of spending for those with disabilities; 18% is paid out-of-pocket, 30% by Medicare, 10% by Medicaid, 10% by other public programs, and 4% by other sources. More than half of all HIV positive Americans are covered by public insurance policies, while private insurance covers only 19%; 29% are uninsured.
Uninsurance rates are highest in the South and West. Texas had the highest rate, 24.5%. Arizona, California. Mississippi, Nevada, and New Mexico also had uninsurance rates of 20% or higher. Hawaii, Iowa, Minnesota, Nebraska, Rhode Island and Vermont had the lowest rates, 9.0% to 10.0%. Forty-Four Million Uninsured

62. Health Insurance: Summary Most important determinant of access to the health care system
Glaring, horrible racial/ethnic disparities
We need:
NATIONAL HEALTH INSURANCE
Does not explain all of disparities
64. Racial/Ethnic Disparities in access to Cardio-Vascular procedures CV disease is number one killer in America
Useful to look at because it addresses a continuum of care

CABG (.23-.68)
28 studies with detailed clinical data
Cath (.03-.85)
CABG (.22-.68)
14 studies examining why not done
Some due to pt refusal –education imp
Physician bias still caused a lot of variation
68. Implicit Bias among MDs Implicit Association Tests
Implicit stereotypes of blacks as less cooperative
58% offered TPA to whites versus 42% blacks
As pro-white bias increased disparity increased
Unconscious bias contributes to disparities
69. Sex and Racial Differences in the Management of Acute Myocardial Infarction, 1994 through 2002 Rates of reperfusion therapy, coronary angiography, and in-hospital death after myocardial infarction, vary according to race with no evidence that the differences have narrowed in recent years.

77. Separate and Unequal Health Care Systems Black and white patients to a large extent are treated by different physicians.
80% of visits by African-Americans were made to 22% of physicians.
Such doctors were less likely to be board certified and reported less access to specialists, diagnostic procedures, and non-emergency hospital admissions.
NEJM 2004;351:575-84
78. Separate and Unequal Health Care Systems 28,000 patients in New York State who underwent coronary artery bypass graft surgery in 1996-97
African Americans were treated by surgeons with risk-adjusted mortality rates 13.8 percent higher than surgeons who treated whites.
Hospital was the primary factor explaining the disparities, suggesting that physician referral patterns may be important determinants of where minorities receive treatment.
79. Nursing Homes Lower-tier facilities 85% or more residents covered by Medicaid, difficulty retaining staff members, have few financial resources and often restrain patients
40% of African-American nursing home residents nationwide reside in lower-tier homes, compared with 9% of white nursing home residents
Competition works only in markets where consumers have choices, and unfortunately, many of these nursing home residents don't have much choice

96. Crude and adjusted odds ratios (OR)* for diabetes by race/ethnicity among adults =18 years of age: NHIS 2000- 2003 After adjustment for selected covariates (Model 3), Hispanics, regardless of their race, were more likely to report having diabetes than non-Hispanic whites. Specifically, Hispanic whites and blacks were 1.56 and 2.64 times, respectively more likely to report having diabetes than non-Hispanic whites after adjusting for selected covariates. The odds ratio for non-Hispanic blacks was 1.45 (95% CI 1.29-1.64).
Non-Hispanic Black 1.46 (1.29-1.64)
All Hispanic 1.60 (1.38-1.87)
When Hispanic blacks were excluded:
Non-Hispanic Black 1.46 (1.29-1.64)
All Hispanic 1.57 (1.35-1.82)
White Hispanics 1.55 (1.31-1.82)

97. When compared to non-Hispanic Whites, Hispanic Whites were less likely to have hypertension before and after adjustment for selected covariates. However, Hispanic blacks were not different from non-Hispanic whites. We repeated the analyses by ethnicity and race:
The pattern for non-Hispanics and Hispanics was very similar. Specifically, blacks exhibited higher odds of hypertension than whites. Moreover, Hispanics whites had lower odds of hypertension than non-Hispanic whites. However, there was no difference between

105. A Systematic Review of Interventions to Improve Diabetes Care in Socially Disadvantaged Populations
7 databases searched for articles 1986- 2004, 17 studies found
Interventions that were consistently associated with the largest negative outcomes:
those that used mainly didactic teaching
focused only on diabetes knowledge.
106. What works? Features most consistent positive effects
cultural tailoring of the intervention
community educators or lay people leading the intervention
one-on-one interventions with individualized assessment and reassessment
incorporating treatment algorithms
focusing on behavior-related tasks
providing feedback
high-intensity interventions (>10 contact times) delivered over a long duration ( 6 months)
107. What works:Community Based Participatory Research
108. Why Should Investigators be Interested in Community Engagement
Need for recruitment and retention
Increasing Political Advocacy for Community Participation in Research: NIH Roadmap
Hispanic Community Health Study
Clinical Translation Science Award
Some areas will be mandated to have community input / collaboration
genomics
Increasing Community Sophistication
109. community-based research Research conducted in a community as a place or setting
Research primarily driven by the academic institution
May address areas of importance for community
Limited involvement of community members
Study subjects
Recruiters, community liaisons, RA’s
110. COMMUNTIY BASED PARTICIPATORY RESEARCH (CBPR) Collaborative approach to research that equitably involves all partners in the research process and recognizes the unique strengths that each brings
Begins with a research topic of importance to the community
Has the aim of combining knowledge with action and achieving social change to improve health outcomes [and eliminate health disparities]
111. Mandates Participatory models of research, in which communities are actively engaged in the research process through partnerships with academic institutions, have become central to the national prevention / disparities research agenda
Calls by IOM, NIH, CDC, AHRQ……
Increasing Evidence Base for CBPR
112. PRINCIPLES OF CBPR Facilitates collaborative, equitable involvement of all partners in all phases of the research.
collaborative partnership in which all parties participate as equal members
share control over all phases of the research process,
e.g., problem definition, data collection, interpretation of results, and application of the results to address community concerns
113. CBPR Involves a collaborative partnership in a cyclical, iterative process in which communities of identity play a lead role in
identifying community strengths and resources
selecting priority issues to address
collecting, interpreting, and translating research findings in ways that will benefit the community
Emphasizes the reciprocal transfer of knowledge, skills, capacity and power.
The focus of the partnership is driven by issues and concerns identified by members of the community of identity.
114. Challenges: Community Distrust of AHCs
Traditional mistrust of research
Guinea Pig phenomenon
Abandonment
“Not in loop”
Failure to carry out with policy / interventions
Not sharing $$$$$
115. Challenges Academic Distrust of Community
Public relations
Politics
Fiscal Integrity
Foreign Culture
Community Capacity to conduct Research
$$$$$$ / Indirect issues
Evaluation
117. Consists of Nine Cores Administrative Core
Research Training Core
Community Action Core
Health Disparities Core (Cultural Competency Core)
Five Research Cores (Access to Care, Cardio-vascular Disease, Mental Health, Injury Prevention, Diabetes)
118. Community Core Specific AIMS: Integrate CBPR into each of CHUM Research Cores/ work of investigators
Partial Success (depends on core leaders/ investigators)
Some cores already doing CBPR
Injury Prevention
Most were doing excellent Community Linkages and continue doing so
Access core, Diabetes Core
Most were not doing and will not do CBPR
Impractical to do CBPR in secondary data analysis
Multi site NIH type Clinical Research hard add CBPR
Highly Successful Investigators do not need to do CBPR
119. Develop Partnerships between CUMC Investigators and CBOs CBPR Clearing House / Match making
Partial success
Investigators present to planning council they decide to participate
Often approach for recruiting after study funded
Mothers using cocaine
Subjects for HIV at risk studies
Some success at investigators approach at start and share resources

CHUM 2 Research: Project Overview Project 1: A randomized controlled clinical trial (RCT) of 360 poorly controlled diabetic patients aged 35-70 to examine the effectiveness of a community based Community Health Worker (CHW) intervention in addressing the ABCs of diabetes care (HgA1c, Blood Pressure[BP], Cholesterol).
Project 2: A prospective study examining the impact of glycemic control on cognitive function among Latino elders with diabetes.
Project 3: An RCT to evaluate the effect of a community-based comprehensive therapeutic lifestyle intervention that includes group sessions and motivational interviewing on blood pressure among Latino elders.
128. Random Thoughts Remember why community wants more minority investigators
Issues not addressed by traditional researchers
New ideas, new approaches
Research to action/ advocacy
Must know much more than others
Not only your field but also demographics, other minority health/ disparities issues
Minority tax- must pay some of it
