    Perspective on the "African American participation in Alzheimer disease research: Effective strategies" workshop, 2018
    (Wiley, 2020-12) Denny, Andrea; Streitz, Marissa; Stock, Kristin; Balls-Berry, Joyce E.; Barnes, Lisa L.; Byrd, Goldie S.; Croff, Raina; Gao, Sujuan; Glover, Crystal M.; Hendrie, Hugh C.; Hu, William T.; Manly, Jennifer J.; Moulder, Krista L.; Stark, Susan; Thomas, Stephen B.; Whitmer, Rachel; Wong, Roger; Morris, John C.; Lingler, Jennifer H.; Psychiatry, School of Medicine
    The Washington University School of Medicine Knight Alzheimer Disease Research Center's "African American Participation in Alzheimer Disease Research: Effective Strategies" Workshop convened to address a major limitation of the ongoing scientific progress regarding Alzheimer's disease and related dementias (ADRD): participants in most ADRD research programs overwhelmingly have been limited to non-Hispanic white persons, thus precluding knowledge as to how ADRD may be represented in non-white individuals. Factors that may contribute to successful recruitment and retention of African Americans into ADRD research were discussed and organized into actionable next steps as described within this report.

    Race-specific associations of 25-hydroxyvitamin D and parathyroid hormone with cardiometabolic biomarkers among US white and black postmenopausal women
    (Elsevier, 2020-08-01) Xia, Jin; Tu, Wanzhu; Manson, JoAnn E.; Nan, Hongmei; Shadyab, Aladdin H.; Bea, Jennifer W.; Cheng, Ting-Yuan D.; Hou, Lifang; Song, Yiqing; Epidemiology, School of Public Health
    Background: Concentrations of 25-hydroxyvitamin D [25(OH)D] tend to be lower in African Americans than in non-Hispanic whites, but whether adding information on parathyroid hormone (PTH) can help explain the higher cardiometabolic risk among African Americans is unknown. Objectives: This study examined race (black/white)-specific independent and joint associations of 25(OH)D and PTH with cardiometabolic biomarkers including high-sensitivity C-reactive protein (hs-CRP), estimated glomerular filtration rate (eGFR), and homeostasis model assessment of insulin resistance (HOMA-IR) and β-cell function (HOMA-B). Methods: Among 1500 white and 1300 black postmenopausal women without cardiovascular disease from the Women's Health Initiative Observational Study, a weighted linear regression analysis and a novel penalized spline-based semiparametric model with contour plots, accounting for possible nonlinear relations and interactions simultaneously, were used to investigate the race-specific independent and joint associations of 25(OH)D and PTH with each biomarker. Results: Black women had lower concentrations of 25(OH)D and higher PTH, HOMA-IR, HOMA-B, hs-CRP, and eGFR than white women (all P values < 0.0001). Lower 25(OH)D and higher PTH were each independently and jointly associated with higher HOMA-IR in both white and black women, whereas a similar joint relation with HOMA-B was observed in white women only. In contrast, PTH was nonlinearly associated with HOMA-B in black women and positively associated with hs-CRP in white women, independently of 25(OH)D. Whereas there was an inverse linear relation between PTH and eGFR in white women after accounting for 25(OH)D, PTH and 25(OH)D were jointly and nonlinearly associated with eGFR in black women. Conclusions: We found that the joint association of 25(OH)D and PTH with β-cell function, systemic inflammation, and kidney function apparently differed between white and black women. Further studies are needed to determine whether differences in the vitamin D-PTH endocrine system contribute to racial disparities in cardiovascular health.

    Racial Differences in Retention in a Community-based Addiction Reduction Program Implemented by Peer Recovery Coaches for Women of Reproductive Age
    (Sage, 2023) Yakovlyeva, Anastasiya; Griffin, Wilma; Worden, Allison; Roth, Sarah; DeChant, Paige; Butler, Dawn; Tang, Qing; Litzelman, Debra K.; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public Health
    To identify program characteristics that influence the retention of women of reproductive age in the Community-based Addiction Reduction program (CARE), mixed-method analyses of CARE survey data and CARE Peer Recovery Coach (PRC) narrative entries of participant encounters were performed. About 251 women were enrolled in this prospective community-based implementation science intervention. We compared survey responses by race for treatment status, treatment motivation scales, and retention in the program at intake, 2-, 6-, 9-, and 12-month follow ups using Chi-square/T-tests. Qualitative analysis of PRC narrative entries was conducted following thematic analysis and crystallization immersion analytic methods. White compared with Black women in CARE were significantly more likely to be in treatment at intake (P < .001) and more motivated to engage in recovery treatment (P < .001). However, Black women were retained longer in CARE at 2- (P < .006), 6- (P < .011), and 9- (P < .004) months. PRC narrative entries were coded, and emergent themes mapped well to the 4 types of supports provided by PRC as outlined by the Substance Abuse and Mental Health Services Administration: emotional, instrumental, informational, and affiliational. Analysis of narrative entries by race revealed that Black women were given more detailed information, communications with PRC were more encouraging and proactive in identifying and meeting needs, and PRC took a more hands-on approach when assisting and linking to resources. The inclusion of PRC as integral members of SUD recovery programs may preferentially provide Black women with SUD the opportunity to build more trusting relationships with these peer coaches, thereby increasing their participation and retention.
