1.  Healthy Families Study: Design of a Childhood Obesity Prevention Trial for Hispanic Families 
Contemporary clinical trials  2013;35(2):108-121.
Background
The childhood obesity epidemic disproportionately affects Hispanics. This paper reports on the design of the ongoing Healthy Families Study, a randomized controlled trial testing the efficacy of a community-based, behavioral family intervention to prevent excessive weight gain in Hispanic children using a community-based participatory research approach.
Methods
The study will enroll 272 Hispanic families with children ages 5–7 residing in greater Nashville, Tennessee, United States. Families are randomized to the active weight gain prevention intervention or an alternative intervention focused on oral health. Lay community health promoters implement the interventions primarily in Spanish in a community center. The active intervention was adapted from the We Can! parent program to be culturally-targeted for Hispanic families and for younger children. This 12-month intervention promotes healthy eating behaviors, increased physical activity, and decreased sedentary behavior, with an emphasis on parental modeling and experiential learning for children. Families attend eight bi-monthly group sessions during four months then receive information and/or support by phone or mail each month for eight months. The primary outcome is change in children’s body mass index. Secondary outcomes are changes in children’s waist circumference, dietary behaviors, preferences for fruits and vegetables, physical activity, and screen time.
Results
Enrollment and data collection are in progress.
Conclusion
This study will contribute valuable evidence on efficacy of a childhood obesity prevention intervention targeting Hispanic families with implications for reducing disparities.

2.  Using a Participatory Research Process to Address Disproportionate Hispanic Cancer Burden 
Journal of health care for the poor and underserved  2010;21(1 0):10.1353/hpu.0.0271.
Community-based participatory research (CBPR) offers great potential for increasing the impact of research on reducing cancer health disparities. This article reports how the Community Outreach Core (COC) of the Meharry-Vanderbilt-Tennessee State University (TSU) Cancer Partnership has collaborated with community partners to develop and implement CBPR. The COC, Progreso Community Center, and Nashville Latino Health Coalition jointly developed and conducted the 2007 Hispanic Health in Nashville Survey as a participatory needs assessment to guide planning for subsequent CBPR projects and community health initiatives. Trained community and student interviewers surveyed 500 Hispanic adults in the Nashville area, using a convenience sampling method. In light of the survey results, NLHC decided to focus in the area of cancer on the primary prevention of cervical cancer. The survey led to a subsequent formative CBPR research project to develop an intervention, then to funding of a CBPR pilot intervention study to test the intervention.

3.  Race, Gender, and Age Differences in Heart Failure-Related Hospitalizations in a Southern State: Implications for Prevention 
Circulation. Heart failure  2010;4(2):161-169.
Background
Since heart failure (HF) is the final common pathway for most heart diseases, we examined its 10-year prevalence trend by race, gender, and age in Tennessee.
Methods and Results
HF hospitalization data from the Tennessee Hospital Discharge Data System were analyzed by race, gender and age. Rates were directly age-adjusted using the Year 2000 standard population. Adult (age 20+) in-patient hospitalization for primary diagnosis of HF (HFPD) increased from 4.2% in 1997 to 4.5% in 2006. Age-adjusted hospitalization for HF (per 10,000 population) rose by 11.3% (from 29.3 in 1997 to 32.6 in 2006). Parallel changes in secondary HF admissions were also noted. Age-adjusted rates were higher among blacks than whites and higher among men than women. The ratios of black to white by gender admitted with HFPD in 2006 were highest (9:1) among the youngest age categories (20-34 and 35-44 years). Furthermore, for each age category of black men below 65 years, there were higher HF admission rates than for white men in the immediate older age category. In 2006, the adjusted rate ratios for HFPD in black to white men aged 20-34 and 35-44 years were OR=4.75, CI (3.29-6.86) and OR 5.10, CI (4.15-6.25) respectively. Hypertension was the independent predictor of HF admissions in black men age 20-34 years.
Conclusions
The higher occurrence of HF among young adults in general, particularly among young black men, highlights the need for prevention by identifying modifiable biological and social determinants in order to reduce cardiovascular health disparities in this vulnerable group.

4.  Increased Black-White Disparities in Mortality After the Introduction of Lifesaving Innovations: A Possible Consequence of US Federal Laws 
American journal of public health  2010;100(11):2176-2184.
Objectives
We explored whether the introduction of 3 lifesaving innovations introduced between 1989 and 1996 increased, decreased, or had no effect on disparities in Black-White mortality in the United States through 2006.
Methods
Centers for Disease Control and Prevention data were used to assess disease-, age-, gender-, and race-specific changes in mortality after the introduction of highly active anti-retroviral therapy (HAART) for treatment of HIV, surfactants for neonatal respiratory distress syndrome, and Medicare reimbursement of mammography screening for breast cancer.
Results
Disparities in Black-White mortality from HIV significantly increased after the introduction of HAART, surfactant therapy, and reimbursement for screening mammography. Between 1989 and 2006, these circumstances may have accounted for an estimated 22441 potentially avoidable deaths among Blacks.
Conclusions
These descriptive data contribute to the formulation of the hypothesis that federal laws promote increased disparities in Black-White mortality by inadvertently favoring Whites with respect to access to lifesaving innovations. Failure of legislation to address known social factors is a plausible explanation, at least in part, for the observed findings. Further research is necessary to test this hypothesis, including analytic epidemiological studies designed a priori to do so.

5.  Diabetes, depression, and healthcare utilization among African Americans in primary care. 
PURPOSE: This study tested for an association between diabetes and depressive symptoms and assessed the effect of co-occurring diabetes and depressive symptoms on healthcare utilization outcomes among African-American patients. PROCEDURE: The sample consisted of 303 adult African-American patients age 40 and over from a primary care clinic serving the low-income population in Nashville, TN. Measures were based on self-reports during a structured interview. Multivariate analyses adjusted for age, gender, socioeconomic status, and comorbid chronic conditions. FINDINGS: African-American patients with and without diabetes did not differ on the presence or severity of depressive symptoms. However, the co-occurrence of major depressive symptoms with diabetes among African Americans was associated with nearly three times more reported emergency room visits and three times more inpatient days, but was only marginally associated with a lower number of physician visits. CONCLUSIONS: In contrast to previous studies with predominantly white samples that found a positive association between diabetes and depression, no association was found in this African-American sample. Nevertheless, the results did concur with research findings based on other samples, in that the co-occurrence of depression with diabetes was associated with more acute care utilization, such as emergency room visits and inpatient hospitalizations. This pattern of utilization may lead to higher healthcare costs among patients with diabetes who are depressed, regardless of race.
