Item Open Access Adherence to Adjuvant Endocrine Therapy in Insured Black and White Breast Cancer Survivors: Exploring Adherence Measures in Patient Data.(Journal of managed care & specialty pharmacy, 2019-05) Sheppard, Vanessa B; He, Jun; Sutton, Arnethea; Cromwell, Lee; Adunlin, Georges; Salgado, Teresa M; Tolsma, Dennis; Trout, Martha; Robinson, Brandi E; Edmonds, Megan C; Bosworth, Hayden B; Tadesse, Mahlet GBackground
Adjuvant endocrine therapy (AET) is a critical therapy in that it improves survival in women with hormone receptor-positive (HR+) breast cancer (BC), but adherence to AET is suboptimal. The purpose of this study was to fill scientific gaps about predictors of adherence to AET among black and white women diagnosed with BC.Objective
To assess AET adherence in black and white insured women using multiple measures, including one that uses an innovative statistical approach.Methods
Black and white women newly diagnosed with HR+ BC were identified from 2 health maintenance organizations. Pharmacy records captured the type of oral AET prescriptions and all fill dates. Multivariable logistic regression was used to identify predictors of adherence defined in terms of proportion of days covered (PDC; ≥ 80%) and medication gap of ≤ 10 days. A zero-inflated negative binomial (ZINB) regression model was used to identify variables associated with the total number of days of medication gaps.Results
1,925 women met inclusion criteria. 80% were PDC adherent (> 80%); 44% had a medication gap of ≤ 10 days; and 24% had no medication gap days. Race and age were significant in all multivariable models. Black women were less likely to be adherent based on PDC than white women (OR = 0.72, 95% CI = 0.57-0.90, P < 0.01), and they were less likely to have a medication gap of ≤ 10 days (OR = 0.65, 95% CI = 0.54-0.79, P < 0.001). Women aged 25-49 years were less likely to be PDC adherent than women aged 65-93 years (OR = 0.65, 95% CI = 0.48-0.87, P < 0.001). In the ZINB model, women were without their medication for an average of 37 days (SD = 50.5).Conclusions
Racial disparities in adherence to AET in the study highlight a need for interventions among insured women. Using various measures of adherence may help better understand this multidimensional concept. There might be benefits from using both more common dichotomous measures (e.g., PDC) and integrating novel statistical approaches to allow tailoring adherence to patterns within a specific sample.Disclosures

We compared barriers to urinary incontinence (UI) healthcare seeking between white, black, and Latina women.Methods
This is a cross-sectional study using a convenience sample of white, black, and Latina women. Women completed the Barriers to Incontinence Care Seeking Questionnaire (BICS-Q), the Incontinence Quality of Life Instrument (I-QOL), the Questionnaire for Urinary Incontinence Diagnosis, and the Incontinence Severity Index (ISI). The primary objective was to assess barriers to UI care seeking among groups, as measured by the BICS-Q. Secondary objectives were to assess factors associated with barriers to incontinence care and to compare specific barriers using BICS-Q subscale scores. Regression analyses were used to further assess for differences among groups while adjusting for potential confounding variables.Results
We included a total of 93 subjects, including 30 white, 33 black, and 30 Latina women. Mean I-QOL, Questionnaire for Urinary Incontinence Diagnosis, and ISI scores were not significantly different among our 3 groups. Barriers, based on BICS-Q scores, were lowest in white women and higher in blacks and Latinas (2.9 vs 7.3 vs 10.9, respectively; P < 0.001). When adjusting for potential confounders such as age, income, education, presence of UI, ISI score, and I-QOL score, Latinas continued to demonstrate higher barriers compared with white or black women (β = 7.4; 95% CI, 2.2-12.7; P = 0.006). There were no significant differences between black women compared with other groups in the adjusted analyses.Conclusions
Latinas experience more barriers to UI healthcare seeking compared with white and black women.Item Open Access Differences in osteoarthritis self-management support intervention outcomes according to race and health literacy.(Health education research, 2013-06) Sperber, Nina R; Bosworth, Hayden B; Coffman, Cynthia J; Lindquist, Jennifer H; Oddone, Eugene Z; Weinberger, Morris; Allen, Kelli DWe explored whether the effects of a telephone-based osteoarthritis (OA) self-management support intervention differed by race and health literacy. Participants included 515 veterans with hip and/or knee OA. Linear mixed models assessed differential effects of the intervention compared with health education (HE) and usual care (UC) on pain (Arthritis Impact Measurement Scales-2 [AIMS2] and Visual Analogue Scale), function (AIMS2 mobility and walking/bending), affect (AIMS2) and arthritis self-efficacy by: (i) race (white/non-white), (ii) health literacy (high/low) and (iii) race by health literacy. AIMS2 mobility improved more among non-whites than whites in the intervention compared with HE and UC (P = 0.02 and 0.008). AIMS2 pain improved more among participants with low than high literacy in the intervention compared with HE (P = 0.05). However, we found a differential effect of the intervention on AIMS2 pain compared with UC according to the combination of race and health literacy (P = 0.05); non-whites with low literacy in the intervention had the greatest improvement in pain. This telephone-based OA intervention may be particularly beneficial for patients with OA who are racial/ethnic minorities and have low health literacy. These results warrant further research designed specifically to assess whether this type of intervention can reduce OA disparities.Item Open Access Follow-up of patients with new cardiovascular implantable electronic devices: are experts' recommendations implemented in routine clinical practice?(Circulation. Arrhythmia and electrophysiology, 2013-02) Al-Khatib, Sana M; Mi, Xiaojuan; Wilkoff, Bruce L; Qualls, Laura G; Frazier-Mills, Camille; Setoguchi, Soko; Hess, Paul L; Curtis, Lesley HBackground
A 2008 expert consensus statement outlined the minimum frequency of follow-up of patients with cardiovascular implantable electronic devices (CIEDs).Methods and results
We studied 38 055 Medicare beneficiaries who received a new CIED between January 1, 2005, and June 30, 2009. The main outcome measure was variation of follow-up by patient factors and year of device implantation. We determined the number of patients who were eligible for and attended an in-person CIED follow-up visit within 2 to 12 weeks, 0 to 16 weeks, and 1 year after implantation. Among eligible patients, 42.4% had an initial in-person visit within 2 to 12 weeks. This visit was significantly more common among white patients than black patients and patients of other races (43.0% versus 36.8% versus 40.5%; P<0.001). Follow-up within 2 to 12 weeks improved from 40.3% in 2005 to 55.1% in 2009 (P<0.001 for trend). The rate of follow-up within 0 to 16 weeks was 65.1% and improved considerably from 2005 to 2009 (62.3%-79.6%; P<0.001 for trend). Within 1 year, 78.0% of the overall population had at least 1 in-person CIED follow-up visit.Conclusions
Although most Medicare beneficiaries who received a new CIED between 2005 and 2009 did not have an initial in-person CIED follow-up visit within 2 to 12 weeks after device implantation, the rate of initial follow-up improved appreciably over time. This CIED follow-up visit was significantly more common in white patients than in patients of other races.Item Open Access Heart matters: Gender and racial differences cardiovascular disease risk factor control among veterans.(Women's health issues : official publication of the Jacobs Institute of Women's Health, 2014-09) Goldstein, Karen M; Melnyk, S Dee; Zullig, Leah L; Stechuchak, Karen M; Oddone, Eugene; Bastian, Lori A; Rakley, Susan; Olsen, Maren K; Bosworth, Hayden BBackground
Cardiovascular disease (CVD) is the leading cause of mortality for U.S. women. Racial minorities are a particularly vulnerable population. The increasing female veteran population has an higher prevalence of certain cardiovascular risk factors compared with non-veteran women; however, little is known about gender and racial differences in cardiovascular risk factor control among veterans.Methods
We used analysis of variance, adjusting for age, to compare gender and racial differences in three risk factors that predispose to CVD (diabetes, hypertension, and hyperlipidemia) in a cohort of high-risk veterans eligible for enrollment in a clinical trial, including 23,955 men and 1,010 women.Findings
Low-density lipoprotein (LDL) values were higher in women veterans than men with age-adjusted estimated mean values of 111.7 versus 97.6 mg/dL (p < .01). Blood pressures (BPs) were higher among African-American than White female veterans with age-adjusted estimated mean systolic BPs of 136.3 versus 133.5 mmHg, respectively (p < .01), and diastolic BPs of 82.4 versus 78.9 mmHg (p < .01). African-American veterans with diabetes had worse BP, LDL values, and hemoglobin A1c levels, although the differences were only significant among men.Conclusions
Female veterans have higher LDL cholesterol levels than male veterans and African-American veterans have higher BP, LDL cholesterol, and A1c levels than Whites after adjusting for age. Further examination of CVD gender and racial disparities in this population may help to develop targeted treatments and strategies applicable to the general population.Item Open Access Home blood pressure management and improved blood pressure control: results from a randomized controlled trial.(Archives of internal medicine, 2011-07) Bosworth, Hayden B; Powers, Benjamin J; Olsen, Maren K; McCant, Felicia; Grubber, Janet; Smith, Valerie; Gentry, Pamela W; Rose, Cynthia; Van Houtven, Courtney; Wang, Virginia; Goldstein, Mary K; Oddone, Eugene ZBackground
To determine which of 3 interventions was most effective in improving blood pressure (BP) control, we performed a 4-arm randomized trial with 18-month follow-up at the primary care clinics at a Veterans Affairs Medical Center.Methods
Eligible patients were randomized to either usual care or 1 of 3 telephone-based intervention groups: (1) nurse-administered behavioral management, (2) nurse- and physician-administered medication management, or (3) a combination of both. Of the 1551 eligible patients, 593 individuals were randomized; 48% were African American. The intervention telephone calls were triggered based on home BP values transmitted via telemonitoring devices. Behavioral management involved promotion of health behaviors. Medication management involved adjustment of medications by a study physician and nurse based on hypertension treatment guidelines.Results
The primary outcome was change in BP control measured at 6-month intervals over 18 months. Both the behavioral management and medication management alone showed significant improvements at 12 months-12.8% (95% confidence interval [CI], 1.6%-24.1%) and 12.5% (95% CI, 1.3%-23.6%), respectively-but not at 18 months. In subgroup analyses, among those with poor baseline BP control, systolic BP decreased in the combined intervention group by 14.8 mm Hg (95% CI, -21.8 to -7.8 mm Hg) at 12 months and 8.0 mm Hg (95% CI, -15.5 to -0.5 mm Hg) at 18 months, relative to usual care.Conclusions
Overall intervention effects were moderate, but among individuals with poor BP control at baseline, the effects were larger. This study indicates the importance of identifying individuals most likely to benefit from potentially resource intensive programs.Trial registration
clinicaltrials.gov Identifier: NCT00237692.Item Open Access HPV genotypes and cervical intraepithelial neoplasia in a multiethnic cohort in the southeastern USA.(Cancer causes & control : CCC, 2014-08) Vidal, Adriana C; Smith, Jennifer S; Valea, Fidel; Bentley, Rex; Gradison, Maggie; Yarnall, Kimberly SH; Ford, Anne; Overcash, Francine; Grant, Kathy; Murphy, Susan K; Hoyo, CathrinePurpose
For poorly understood reasons, invasive cervical cancer (ICC) incidence and mortality rates are higher in women of African descent. Oncogenic human papillomavirus (HPV) genotypes distribution may vary between European American (EA) and African-American (AA) women and may contribute to differences in ICC incidence. The current study aimed at disentangling differences in HPV distribution among AA and EA women.Methods
Five-hundred and seventy-two women were enrolled at the time of colposcopic evaluation following an abnormal liquid-based cytology screen. HPV infections were detected using HPV linear array, and chi-squared tests and linear regression models were used to compare HPV genotypes across racial/ethnic groups by CIN status.Results
Of the 572 participants, 494 (86 %) had detectable HPV; 245 (43 %) had no CIN lesion, 239 (42 %) had CIN1, and 88 (15 %) had CIN2/3. Seventy-three percent of all women were infected with multiple HPV genotypes. After adjusting for race, age, parity, income, oral contraception use, and current smoking, AAs were two times less likely to harbor HPV 16/18 (OR 0.48, 95 % CI 0.21-0.94, p = 0.03) when all women were considered. This association remained unchanged when only women with CIN2/3 lesions were examined (OR 0.22, 95 % CI 0.05-0.95, p = 0.04). The most frequent high-risk HPV genotypes detected among EAs were 16, 18, 56, 39, and 66, while HPV genotypes 33, 35, 45, 58, and 68 were the most frequent ones detected in AAs.Conclusions
Our data suggest that while HPV 16/18 are the most common genotypes among EA women with CIN, AAs may harbor different genotypes.Item Open Access Immigration and health among non-Hispanic whites: The impact of arrival cohort and region of birth.(Social science & medicine (1982), 2020-02) Read, Jen'nan Ghazal; West, Jessica S; Kamis, ChristinaImmigration is central to our understanding of U.S. racial and ethnic health disparities, yet relatively little is known about the health of white immigrants - a group whose ethnic origins have become increasingly diverse. To the extent that whites are included in social stratification research, they are typically used as the reference category for gauging health inequities, with little attention to diversity among them. This study addresses this question using nationally representative data from the American Community Survey (2008-2017). We disaggregate non-Hispanic whites by nativity, region of birth, and period of arrival in the U.S. and examine differences in physical disability among adults aged 40 and older (n = 12, 075, 638). The analysis finds that foreign-born whites have a slightly lower prevalence of disability than U.S.-born whites, and this varies by arrival cohort. Immigrants who arrived in the 1981-1990 and 1991-2000 cohorts have a smaller advantage over U.S.-born whites than immigrants in the earlier and later cohorts. Compositional changes in the region of birth of white immigrants, especially the influx of eastern Europeans and Middle Easterners during the 1980s and 1990s, explained this variation. These findings challenge the oft-assumed notion that whites are a monolithic group and highlight growing intra-ethnic heterogeneity that is obscured by the aggregate category. Our findings also suggest that the standard practice of using whites as the reference for benchmarking health inequities may mask health inequities not only among them, but also between whites and other racial and ethnic populations.Item Open Access Impact of inflammatory biomarkers on relation of high density lipoprotein-cholesterol with incident coronary heart disease: cardiovascular Health Study.(Atherosclerosis, 2013-12) Tehrani, David M; Gardin, Julius M; Yanez, David; Hirsch, Calvin H; Lloyd-Jones, Donald M; Stein, Phyllis K; Wong, Nathan DBackground
Inflammatory factors and low HDL-C relate to CHD risk, but whether inflammation attenuates any protective association of high HDL-C is unknown.Objective
Investigate inflammatory markers' individual and collective impact on the association of HDL-C with incident coronary heart disease (CHD).Methods
In 3888 older adults without known cardiovascular disease (CVD), we examined if the inflammatory markers C-reactive protein (CRP), interleukin-6 (IL-6), and lipoprotein-associated phospholipase A2 (Lp-PLA₂) modify the relation of HDL-C with CHD. HDL-C, CRP, IL-6, and Lp-PLA₂ values were grouped as using gender-specific tertiles. Also, an inflammation index of z-score sums for CRP, IL-6, and Lp-PLA₂ was categorized into tertiles. We calculated CHD incidence for each HDL-C/inflammation group and performed Cox regression, adjusted for standard CVD risk factors and triglycerides to examine the relationship of combined HDL-C-inflammation groups with incident events.Results
CHD incidence (per 1000 person years) was higher for higher levels of CRP, IL-6, and the index, and lower for higher levels of HDL-C. Compared to high HDL-C/low-inflammation categories (referent), adjusted HRs for incident CHD were increased for those with high HDL-C and high CRP (HR = 1.50, p < 0.01) or highest IL-6 tertile (HR = 1.40, p < 0.05), but not with highest Lp-PLA₂ tertile. Higher CHD incidence was similarly seen for those with intermediate or low HDL-C accompanied by high CRP, high IL-6, or a high inflammatory index.Conclusion
The protective relation of high HDL-C for incident CHD appears to be attenuated by greater inflammation.Item Open Access International meta-analysis of PTSD genome-wide association studies identifies sex- and ancestry-specific genetic risk loci.(Nature communications, 2019-10) Nievergelt, Caroline M; Maihofer, Adam X; Klengel, Torsten; Atkinson, Elizabeth G; Chen, Chia-Yen; Choi, Karmel W; Coleman, Jonathan RI; Dalvie, Shareefa; Duncan, Laramie E; Gelernter, Joel; Levey, Daniel F; Logue, Mark W; Polimanti, Renato; Provost, Allison C; Ratanatharathorn, Andrew; Stein, Murray B; Torres, Katy; Aiello, Allison E; Almli, Lynn M; Amstadter, Ananda B; Andersen, Søren B; Andreassen, Ole A; Arbisi, Paul A; Ashley-Koch, Allison E; Austin, S Bryn; Avdibegovic, Esmina; Babić, Dragan; Bækvad-Hansen, Marie; Baker, Dewleen G; Beckham, Jean C; Bierut, Laura J; Bisson, Jonathan I; Boks, Marco P; Bolger, Elizabeth A; Børglum, Anders D; Bradley, Bekh; Brashear, Megan; Breen, Gerome; Bryant, Richard A; Bustamante, Angela C; Bybjerg-Grauholm, Jonas; Calabrese, Joseph R; Caldas-de-Almeida, José M; Dale, Anders M; Daly, Mark J; Daskalakis, Nikolaos P; Deckert, Jürgen; Delahanty, Douglas L; Dennis, Michelle F; Disner, Seth G; Domschke, Katharina; Dzubur-Kulenovic, Alma; Erbes, Christopher R; Evans, Alexandra; Farrer, Lindsay A; Feeny, Norah C; Flory, Janine D; Forbes, David; Franz, Carol E; Galea, Sandro; Garrett, Melanie E; Gelaye, Bizu; Geuze, Elbert; Gillespie, Charles; Uka, Aferdita Goci; Gordon, Scott D; Guffanti, Guia; Hammamieh, Rasha; Harnal, Supriya; Hauser, Michael A; Heath, Andrew C; Hemmings, Sian MJ; Hougaard, David Michael; Jakovljevic, Miro; Jett, Marti; Johnson, Eric Otto; Jones, Ian; Jovanovic, Tanja; Qin, Xue-Jun; Junglen, Angela G; Karstoft, Karen-Inge; Kaufman, Milissa L; Kessler, Ronald C; Khan, Alaptagin; Kimbrel, Nathan A; King, Anthony P; Koen, Nastassja; Kranzler, Henry R; Kremen, William S; Lawford, Bruce R; Lebois, Lauren AM; Lewis, Catrin E; Linnstaedt, Sarah D; Lori, Adriana; Lugonja, Bozo; Luykx, Jurjen J; Lyons, Michael J; Maples-Keller, Jessica; Marmar, Charles; Martin, Alicia R; Martin, Nicholas G; Maurer, Douglas; Mavissakalian, Matig R; McFarlane, Alexander; McGlinchey, Regina E; McLaughlin, Katie A; McLean, Samuel A; McLeay, Sarah; Mehta, Divya; Milberg, William P; Miller, Mark W; Morey, Rajendra A; Morris, Charles Phillip; Mors, Ole; Mortensen, Preben B; Neale, Benjamin M; Nelson, Elliot C; Nordentoft, Merete; Norman, Sonya B; O'Donnell, Meaghan; Orcutt, Holly K; Panizzon, Matthew S; Peters, Edward S; Peterson, Alan L; Peverill, Matthew; Pietrzak, Robert H; Polusny, Melissa A; Rice, John P; Ripke, Stephan; Risbrough, Victoria B; Roberts, Andrea L; Rothbaum, Alex O; Rothbaum, Barbara O; Roy-Byrne, Peter; Ruggiero, Ken; Rung, Ariane; Rutten, Bart PF; Saccone, Nancy L; Sanchez, Sixto E; Schijven, Dick; Seedat, Soraya; Seligowski, Antonia V; Seng, Julia S; Sheerin, Christina M; Silove, Derrick; Smith, Alicia K; Smoller, Jordan W; Sponheim, Scott R; Stein, Dan J; Stevens, Jennifer S; Sumner, Jennifer A; Teicher, Martin H; Thompson, Wesley K; Trapido, Edward; Uddin, Monica; Ursano, Robert J; van den Heuvel, Leigh Luella; Van Hooff, Miranda; Vermetten, Eric; Vinkers, Christiaan H; Voisey, Joanne; Wang, Yunpeng; Wang, Zhewu; Werge, Thomas; Williams, Michelle A; Williamson, Douglas E; Winternitz, Sherry; Wolf, Christiane; Wolf, Erika J; Wolff, Jonathan D; Yehuda, Rachel; Young, Ross McD; Young, Keith A; Zhao, Hongyu; Zoellner, Lori A; Liberzon, Israel; Ressler, Kerry J; Haas, Magali; Koenen, Karestan CThe risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5-20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men. Along with other novel genes and non-coding RNAs, a Parkinson's disease gene involved in dopamine regulation, PARK2, is associated with PTSD. Finally, we demonstrate that polygenic risk for PTSD is significantly predictive of re-experiencing symptoms in the Million Veteran Program dataset, although specific loci did not replicate. These results demonstrate the role of genetic variation in the biology of risk for PTSD and highlight the necessity of conducting sex-stratified analyses and expanding GWAS beyond European ancestry populations.Item Open Access Medication rebates and health disparities: Mind the gap.(Research in social & administrative pharmacy : RSAP, 2020-03) Zullig, Leah L; Granger, Bradi B; Vilme, Helene; Oakes, Megan M; Bosworth, Hayden BCompared to white patients in the United States, people of racial and ethnic minority groups face higher rates of chronic disease including diabetes, obesity, stroke, cardiovascular disease and cancer. Minority groups are also less likely to receive medication therapy to manage complications of chronic disease as well as be adherent to these therapies. A recently announced proposed rule by the Department of Health and Human Services Office of the Inspector General (HHS OIG), which would discourage rebates between manufacturers and payers in favor of discounts directly provided to patients, has received significant attention for its anticipated impact on prescription drug pricing and reimbursement in Medicare. This commentary describes the proposed rule and how it may impact adherence among patients of racial minority groups through an illustrative case study and discussion.Item Open Access Race and ethnicity: Risk factors for fungal infections?(PLoS pathogens, 2023-01) Jenks, Jeffrey D; Aneke, Chioma Inyang; Al-Obaidi, Mohanad M; Egger, Matthias; Garcia, Lorena; Gaines, Tommi; Hoenigl, Martin; Thompson, George RRacial and ethnic identities, largely understood as social rather than biologic constructs, may impact risk for acquiring infectious diseases, including fungal infections. Risk factors may include genetic and immunologic differences such as aberrations in host immune response, host polymorphisms, and epigenomic factors stemming from environmental exposures and underlying social determinants of health. In addition, certain racial and ethnic groups may be predisposed to diseases that increase risk for fungal infections, as well as disparities in healthcare access and health insurance. In this review, we analyzed racial and ethnic identities as risk factors for acquiring fungal infections, as well as race and ethnicity as they relate to risk for severe disease from fungal infections. Risk factors for invasive mold infections such as aspergillosis largely appear related to environmental differences and underlying social determinants of health, although immunologic aberrations and genetic polymorphisms may contribute in some circumstances. Although black and African American individuals appear to be at high risk for superficial and invasive Candida infections and cryptococcosis, the reasons for this are unclear and may be related to underling social determinants of health, disparities in access to healthcare, and other socioeconomic disparities. Risk factors for all the endemic fungi are likely largely related to underlying social determinants of health, socioeconomic, and health disparities, although immunologic mechanisms likely play a role as well, particularly in disseminated coccidioidomycosis.Item Open Access Racial differences in nocturnal dipping status in diabetic kidney disease: Results from the STOP-DKD (Simultaneous Risk Factor Control Using Telehealth to Slow Progression of Diabetic Kidney Disease) study.(Journal of clinical hypertension (Greenwich, Conn.), 2017-12) Zullig, Leah L; Diamantidis, Clarissa J; Bosworth, Hayden B; Bhapkar, Manjushri V; Barnhart, Huiman; Oakes, Megan M; Pendergast, Jane F; Miller, Julie J; Patel, Uptal DWhile racial variation in ambulatory blood pressure (BP) is known, patterns of diurnal dipping in the context of diabetic kidney disease have not been well defined. The authors sought to determine the association of race with nocturnal dipping status among participants with diabetic kidney disease enrolled in the STOP-DKD (Simultaneous Risk Factor Control Using Telehealth to Slow Progression of Diabetic Kidney Disease) trial. The primary outcome was nocturnal dipping-percent decrease in average systolic BP from wake to sleep-with categories defined as reverse dippers (decrease <0%), nondippers (0%-<10%), and dippers (≥10%). Twenty-four-hour ambulatory BP monitoring was completed by 108 participants (54% were nondippers, 24% were dippers, and 22% were reverse dippers). In adjusted models, the common odds of reverse dippers vs nondippers/dippers and reverse dippers/nondippers vs dippers was 2.6 (95% confidence interval, 1.2-5.8) times higher in blacks than in whites. Without ambulatory BP monitoring data, interventions that target BP in black patients may be unable to improve outcomes in this high-risk group.Item Open Access Racial Differences in the Effect of a Telephone-Delivered Hypertension Disease Management Program.(Journal of general internal medicine, 2012-08) Jackson, GL; Oddone, EZ; Olsen, MK; Powers, BJ; Grubber, JM; McCant, F; Bosworth, HBBACKGROUND: African Americans are significantly more likely than whites to have uncontrolled hypertension, contributing to significant disparities in cardiovascular disease and events. OBJECTIVE: The goal of this study was to examine whether there were differences in change in blood pressure (BP) for African American and non-Hispanic white patients in response to a medication management and tailored nurse-delivered telephone behavioral program. PARTICIPANTS: Five hundred and seventy-three patients (284 African American and 289 non-Hispanic white) primary care patients who participated in the Hypertension Intervention Nurse Telemedicine Study (HINTS) clinical trial. INTERVENTIONS: Study arms included: 1) nurse-administered, physician-directed medication management intervention, utilizing a validated clinical decision support system; 2) nurse-administered, behavioral management intervention; 3) combined behavioral management and medication management intervention; and 4) usual care. All interventions were activated based on poorly controlled home BP values. MAIN MEASURES: Post-hoc analysis of change in systolic and diastolic blood pressure. General linear models (PROC MIXED in SAS, version 9.2) were used to estimate predicted means at 6-month, 12-month, and 18-month time points, by intervention arm and race subgroups (separate models for systolic and diastolic blood pressure). KEY RESULTS: Improvement in mean systolic blood pressure post-baseline was greater for African American patients in the combined intervention, compared to African American patients in usual care, at 12 months (6.6 mmHg; 95 % CI: -12.5, -0.7; p = 0.03) and at 18 months (9.7 mmHg; -16.0, -3.4; p = 0.003). At 18 months, mean diastolic BP was 4.8 mmHg lower (95 % CI: -8.5, -1.0; p = 0.01) among African American patients in the combined intervention arm, compared to African American patients in usual care. There were no analogous differences for non-Hispanic white patients. CONCLUSIONS: The combination of home BP monitoring, remote medication management, and telephone tailored behavioral self-management appears to be particularly effective for improving BP among African Americans. The effect was not seen among non-Hispanic white patients.Item Open Access Racial Differences in the Effectiveness of a Multifactorial Telehealth Intervention to Slow Diabetic Kidney Disease.(Medical care, 2020-11) Kobe, Elizabeth A; Diamantidis, Clarissa J; Bosworth, Hayden B; Davenport, Clemontina A; Oakes, Megan; Alexopoulos, Anastasia-Stefania; Pendergast, Jane; Patel, Uptal D; Crowley, Matthew JBackground
African Americans are significantly more likely than non-African Americans to have diabetes, chronic kidney disease, and uncontrolled hypertension, increasing their risk for kidney function decline.Objective
The objective of this study was to compare how African Americans and non-African Americans with diabetes responded to a multifactorial telehealth intervention designed to slow kidney function decline.Research design
Secondary analysis of a randomized trial. Primary care patients (N=281, 56% African American) were allocated to either: (1) a multifactorial, pharmacist-delivered phone-based telehealth intervention focused on behavioral and medication management of diabetic kidney disease; or (2) an education control.Measures
The primary study outcome was change in estimated glomerular filtration rate (eGFR). Linear mixed models were used to explore the moderating effect of race on the relationship between study arm and eGFR decline over time; the mean annual rate of eGFR decline was estimated by race and study arm.Results
Findings demonstrated a differential intervention effect on kidney function over time by race (Pinteraction=0.005). Among African Americans, the intervention arm had significantly greater preservation of eGFR over time than the control arm (difference in the annual rate of eGFR decline=1.5 mL/min/1.73 m; 95% confidence interval: 0.04, 3.02). For non-African Americans, the intervention arm had a faster decline in eGFR over time than the control arm (difference in the annual rate of eGFR decline=-1.7 mL/min/1.73 m; 95% confidence interval: -3.3, -0.02).Conclusion
A multifactorial, pharmacist-delivered telehealth intervention for diabetic kidney disease may be more effective for slowing eGFR decline among African Americans than non-African Americans.Item Open Access Track: A randomized controlled trial of a digital health obesity treatment intervention for medically vulnerable primary care patients.(Contemporary clinical trials, 2016-05) Foley, Perry; Steinberg, Dori; Levine, Erica; Askew, Sandy; Batch, Bryan C; Puleo, Elaine M; Svetkey, Laura P; Bosworth, Hayden B; DeVries, Abigail; Miranda, Heather; Bennett, Gary GIntroduction
Obesity continues to disproportionately affect medically vulnerable populations. Digital health interventions may be effective for delivering obesity treatment in low-resource primary care settings.Methods
Track is a 12-month randomized controlled trial of a digital health weight loss intervention in a community health center system. Participants are 351 obese men and women aged 21 to 65years with an obesity-related comorbidity. Track participants are randomized to usual primary care or to a 12-month intervention consisting of algorithm-generated tailored behavior change goals, self-monitoring via mobile technologies, daily self-weighing using a network-connected scale, skills training materials, 18 counseling phone calls with a Track coach, and primary care provider counseling. Participants are followed over 12months, with study visits at baseline, 6, and 12months. Anthropometric data, blood pressure, fasting lipids, glucose and HbA1C and self-administered surveys are collected. Follow-up data will be collected from the medical record at 24months.Results
Participants are 68% female and on average 50.7years old with a mean BMI of 35.9kg/m(2). Participants are mainly black (54%) or white (33%); 12.5% are Hispanic. Participants are mostly employed and low-income. Over 20% of the sample has hypertension, diabetes and hyperlipidemia. Almost 27% of participants currently smoke and almost 20% score above the clinical threshold for depression.Conclusions
Track utilizes an innovative, digital health approach to reduce obesity and chronic disease risk among medically vulnerable adults in the primary care setting. Baseline characteristics reflect a socioeconomically disadvantaged, high-risk patient population in need of evidence-based obesity treatment.Item Open Access Urinary Incontinence and Health-Seeking Behavior Among White, Black, and Latina Women.(Female pelvic medicine & reconstructive surgery, 2016-09) Siddiqui, Nazema Y; Ammarell, Natalie; Wu, Jennifer M; Wu, Jennifer M; Sandoval, Juan S; Bosworth, Hayden BObjective
Fewer than half of women with urinary incontinence (UI) seek care for their condition. Our objective was to qualitatively assess the themes surrounding treatment-seeking behaviors.Methods
We conducted 12 focus groups with women and, using purposive sampling, we stratified by racial or ethnic group (white, black, Latina) and by UI frequency. All sessions were transcribed and coded for common themes. Comparative thematic analysis was used to describe similarities and differences among groups.Results
In total, 113 (39 white, 41 black, and 33 Latina) community-dwelling women participated in focus groups. There were no differences in treatment-seeking themes between groups with different UI frequency. However, certain themes emerged when comparing racial/ethnic groups. Women from all groups shared experiences of embarrassment and isolation because of UI, which were impediments to care seeking. White and black women described discussions with close friends or family that led to normalization of symptoms and prevented care seeking. Latina women maintained more secrecy about UI and reported the longest delays in seeking care. Women articulated a higher likelihood of seeking care if they had knowledge of treatment options, but white women were more likely to seek UI-related knowledge compared with black or Latina women. Physician communication barriers were identified in all groups.Conclusions
Despite similar experiences, there are different perceptions about care seeking among white, black, and Latina women. Culturally relevant educational resources that focus on a range of treatment options may improve knowledge and thus improve care-seeking behaviors in women with UI.Item Open Access Use of health care utilization as a metric of intervention success may perpetuate racial disparities: An outcome evaluation of a homeless transitional care program.(Public health nursing (Boston, Mass.), 2022-11) Nohria, Raman; Biederman, Donna J; Sloane, Richard; Thibault, AlysonObjective
This study explored race-based differences in disease burden, health care utilization, and mortality for Black and White persons experiencing homelessness (PEH) who were referred to a transitional care program, and health care utilization and program outcomes for program participants.Design
This was a quantitative program evaluation.Sample
Black and White PEH referred to a transitional care program (n = 450). We also analyzed data from the subgroup of program participants (N = 122). Of the 450 referrals, 122 participants enrolled in the program.Measures
We included chronic disease burden, mental illness, substance use, health care utilization, and mortality rates for all PEH referred. For program participants, we added 6-month pre/post health care utilization and program outcomes. All results were dichotomized by race.Results
Black PEH who were referred to the program had higher rates of hypertension, diabetes, renal failure, and HIV and similar post-referral mortality rates compared to White PEH. Black and White PEH exhibited similar program outcomes; however, Black PEH revisited the emergency department (ED) less frequently than White PEH at 30 and 90 days after participating in the program.Conclusions
Health care utilization may be a misleading indicator of medical complexity and morbidity among Black PEH. Interventions that rely on health care utilization as an outcome measure may unintentionally contribute to racial disparities.
