Lower serum 25(OH)D levels associated with higher risk of COVID-19 infection in U.S. Black women.

OBJECTIVE: Limited evidence suggests that higher levels of serum vitamin D (25(OH)D) protect against SARS-CoV-2 virus (COVID-19) infection. Black women commonly experience 25(OH)D insufficiency and are overrepresented among COVID-19 cases. We conducted a prospective analysis of serum 25(OH)D levels in relation to COVID-19 infection among participants in the Black Women's Health Study. METHODS: Since 1995, the Black Women's Health Study has followed 59,000 U.S. Black women through biennial mailed or online questionnaires. Over 13,000 study participants provided a blood sample in 2013-2017. 25(OH)D assays were performed in a certified national laboratory shortly after collection of the samples. In 2020, participants who had completed the online version of the 2019 biennial health questionnaire were invited to complete a supplemental online questionnaire assessing their experiences related to the COVID-19 pandemic, including whether they had been tested for COVID-19 infection and the result of the test. We used logistic regression analysis to estimate odds ratios (OR) and 95% confidence intervals (CI) for the association of 25(OH)D level with COVID-19 positivity, adjusting for age, number of people living in the household, neighborhood socioeconomic status, and other potential confounders. RESULTS: Among 5,081 eligible participants whose blood sample had been assayed for 25(OH)D, 1,974 reported having had a COVID-19 test in 2020. Relative to women with 25(OH)D levels of 30 ng/mL (75 nmol/l) or more, multivariable-adjusted ORs for COVID-19 infection in women with levels of 20-29 ng/mL (50-72.5 nmol/l) and <20 ng/mL (<50 nmol/l) were, respectively, 1.48 (95% CI 0.95-2.30) and 1.69 (95% CI 1.04-2.72) (p trend 0.02). CONCLUSION: The present results suggest that U.S. Black women with lower levels of 25(OH)D are at increased risk of infection with COVID-19. Further work is needed to confirm these findings and determine the optimal level of 25(OH)D for a beneficial effect.

The Retail Food Environment, Store Foods, and Diet and Health among Indigenous Populations: a Scoping Review.

PURPOSE OF THE REVIEW: Describe the state of knowledge on how the retail food environment contributes to diet-related health and obesity among Indigenous populations, and assess how the literature incorporates Indigenous perspectives, methodologies and engagement throughout the research process. Outcomes included dietary behaviour (purchasing, intakes and diet quality) and diet-related health outcomes (weight-related outcomes, non-communicable diseases and holistic health or definitions of health as defined by Indigenous populations involved in the study). RECENT FINDINGS: Of fifty included articles (1996-2019), the largest proportions described Indigenous communities in Canada (20 studies, 40%), the USA (16, 32%) and Australia (9, 18%). Among articles that specified the Indigenous population of focus (42 studies, 84%), the largest proportion (11 studies, 26%) took place in Inuit communities, followed by Aboriginal and Torres Strait Islander communities (8 studies, 19%). The included literature encompassed four main study designs: type A, dietary intakes of store foods (14 studies, 28%), and type B, store food environments (16, 32%), comprised the greatest proportion of articles; the remainder were type C, store food environments and diet (7, 14%), and type D, store food environment interventions (13, 26%). Of the studies that assessed diet or health outcomes (36, 72%), 22 (61%) assessed dietary intakes; 16 (44%) sales/purchasing; and 8 (22%) weight-related outcomes. Store foods tended to contribute the greatest amount of dietary energy to the diets of Indigenous peoples and increased non-communicable disease risk as compared to traditional foods. Multi-pronged interventions appeared to have positive impacts on dietary behaviours, food purchasing and nutrition knowledge; promotion and nutrition education alone had more mixed effects. Of the nine studies which were found to have strong engagement with Indigenous populations, eight had moderate or high methodological quality. Eighteen studies (36%) did not mention any engagement with Indigenous populations. The literature confirmed the importance of store foods to the total energy intake of the contemporary diets of Indigenous people, the gaps in accessing both retail food environments and traditional foods and the potential for both new dietary assessment research and retail food environment intervention strategies to better align with and privilege Indigenous Ways of Knowing.

Incidence of Combat Sport-Related Mild Traumatic Brain Injuries Presenting to the Emergency Department From 2012 to 2016.

OBJECTIVES: We sought to investigate the incidence and characteristics of traumatic brain injuries [mild traumatic brain injury (MTBI)] presenting to the emergency department as a result of boxing, wrestling, and martial arts (MA). DESIGN: Retrospective cross-sectional study of MTBI in combat sport athletes who were evaluated in emergency departments in the United States. SETTING: Patient data were taken from the National Electronic Injury Surveillance System. PARTICIPANTS: All patients with MTBI from 2012 to 2016, which occurred during participation in boxing, MA, or wrestling. INTERVENTIONS: None. MAIN OUTCOME MEASURES: The incidence of combat sport-related MTBI presenting to emergency departments in the United States. RESULTS: The mean annual incidence of MTBI due to wrestling was significantly larger (269.3 per 100 000 person-years) than boxing (85.6 per 100 000 person-years) and MA (61.0 per 100 000 person-years) (P < 0.01). The average age at injury was significantly lower for wrestling compared with boxing and MA (15.0 years [SD ± 3.9] vs 21.7 years [SD ± 8.2] vs 19.9 years [SD ± 10.5]; P < 0.01). A significantly larger proportion of MTBIs (95.3%; P < 0.01) in patients younger than 20 years were related to wrestling, compared with boxing (55.8%) and MA (54.1%). Most patients with combat sport-related MTBIs were treated and discharged (96.3%), with only 1.7% of patients being admitted and 0.6% of patients being held for observation. CONCLUSION: Combat sports athletes are at high risk of sustaining an MTBI. Such athletes presenting to the emergency department for combat sport-related MTBI were more likely to be male and younger than 20 years. Of these athletes, wrestlers experience the highest incidence of MTBI-related emergency department visits.

The Not Underrepresented Minorities: Asian Americans, Diversity, and Admissions.

Several lawsuits have recently been filed against U.S. universities; the plaintiffs contend that considerations of race and ethnicity in admissions decisions discriminate against Asian Americans. In prior cases brought by non-Latino whites, the U.S. Supreme Court has upheld these considerations, arguing that they are crucial to a compelling interest to increase diversity. The dissenting opinion, however, concerns the possibility that such policies disadvantage Asian Americans, who are considered overrepresented in higher education. Here, the authors explain how a decision favoring the plaintiffs would affect U.S. medical schools. First, eliminating race and ethnicity in holistic review would undermine efforts to diversify the physician workforce. Second, the restrictions on considering race/ethnicity in admissions decisions would not remedy potential discrimination against Asian Americans that arise from implicit biases. Third, such restrictions would exacerbate the difficulty of addressing the diversity of experiences within Asian American subgroups, including recognizing those who are underrepresented in medicine. The authors propose that medical schools engage Asian Americans in diversity and inclusion efforts and recommend the following strategies: incorporate health equity into the institutional mission and admissions policies, disaggregate data to identify underrepresented Asian subgroups, include Asian Americans in diversity committees and support faculty who make diversity work part of their academic portfolio, and enhance the Asian American faculty pipeline through support and mentorship of students. Asian Americans will soon comprise one-fifth of the U.S. physician workforce and should be welcomed as part of the solution to advancing diversity and inclusion in medicine, not cast as the problem.

Lyme Disease and the Epistemic Tensions of "Medically Unexplained Illnesses".

In the US, disagreement over the biological basis of "chronic Lyme disease" has resulted in the institutionalization of two standards of care: "mainstream" and "Lyme-literate." For mainstream physicians, chronic Lyme disease is a "medically unexplained illness" that presents with an abundance of "symptoms" in the absence of diagnostic "signs." For Lyme-literate physicians, and complementary and alternative medicine practitioners more generally, symptoms alone provide sufficient evidence for medical explanation. Drawing upon ethnographic research among mainstream and Lyme-literate physicians, I suggest that medically unexplained illness is not a biomedical anomaly but an intrinsic feature of biomedicine.

Tea consumption and breast cancer risk in a cohort of women with family history of breast cancer.

Laboratory studies have observed chemopreventive effects of black and green tea on breast cancer development, but few epidemiologic studies have identified such effects. We investigated the association between tea consumption and breast cancer risk using data from 45,744 U.S. and Puerto Rican women participating in the Sister Study. Frequency and serving size of black and green tea consumption were measured at cohort enrollment. Breast cancer diagnoses were reported during follow-up and confirmed by medical record review. Multivariable Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI). We further investigated potential variation according to estrogen receptor (ER) status, menopausal status and body mass index (BMI). Overall, 81.6 and 56.0% of women drank black or green tea, respectively. A total of 2,809 breast cancer cases were identified in the cohort. The multivariable model suggested an inverse association between black (≥5 vs. 0 cups/week: HR = 0.88, 95% CI 0.78, 1.00, p-trend = 0.08) and green tea (≥5 vs. 0 cups/week: HR = 0.82, 95% CI 0.70, 0.95, p-trend < 0.01) consumption and breast cancer risk. We did not observe differences by ER characteristics, menopausal status or BMI. In conclusion, our study suggests drinking at least five cups of green or black tea per week may be associated with decreased breast cancer risk.

Diet Quality of Pregnant American Indian Women in the Northern Plains.

INTRODUCTION: We examined diet quality and intake of pregnancy-specific micronutrients among pregnant American Indian women in the Northern Plains. METHODS: We conducted an analysis of nutrition data from the Prenatal Alcohol and SIDS and Stillbirth (PASS) Network Safe Passage Study and the PASS Diet Screener study (N = 170). Diet intake, including dietary supplementation, was assessed by using three 24-hour recalls conducted on randomly selected, nonconsecutive days. Diet intake data were averaged across the participant's recalls and scored for 2 dietary indices: the Healthy Eating Index 2010 (HEI-2010) and the Alternate Healthy Eating Index for Pregnancy (AHEI-P). We also assessed nutrient adequacy with Dietary Reference Intakes for pregnancy. RESULTS: On average, participants were aged 26.9 (standard deviation [SD], 5.5) years with a pre-pregnancy body mass index of 29.8 (SD, 7.5) kg/m2. Mean AHEI-P and HEI-2010 scores (52.0 [SD, 9.0] and 49.2 [SD, 11.1], respectively) indicated inadequate adherence to dietary recommendations. Micronutrient intake for vitamins D and K, choline, calcium, and potassium were lower than recommended, and sodium intake was higher than recommended. CONCLUSION: Our findings that pregnant American Indian women are not adhering to dietary recommendations is consistent with studies in other US populations. Identifying opportunities to partner with American Indian communities is necessary to ensure effective and sustainable interventions to promote access to and consumption of foods and beverages that support the adherence to recommended dietary guidelines during pregnancy.

Employing Evidence in Evaluating Complementary Therapies: Findings from an Ethnography of Integrative Pain Management at a Large Urban Pediatric Hospital.

BACKGROUND: Complementary and Integrative Medicine (CIM) shows positive clinical benefit with minimal side effects, yet, challenges to effective integration of CIM providers in biomedical health care settings remain. This study aimed to better understand the role evidence played in the process of integration of complementary therapies into a large urban pediatric hospital from the perspective of patients, caregivers, providers, and administrators through applied medical ethnography. METHODS: An ethnography was conducted over the course of 6 months in a large urban pediatric hospital in the Southern United States. At the time, the hospital was piloting an integrative medicine (IM) pain consult service. Purposive sampling was used to select providers, patients, administrators, and caregivers to follow as they engaged with both the preexisting pain service and pilot IM pain services. Field observation and interviews were conducted with 34 participants. Thematic content analysis was used to analyze field notes, interview transcripts, and documents collected. FINDINGS: Analysis of the data revealed five themes regarding the role of evidence in the process of integration: Anecdotal Evidence and Personal Experience Effecting CIM Use, Open to Trying Whatever Works, Resistance to the Unfamiliar, Patients and Parents Trusting Doctors as Experts, and Importance of Scientific Evidence to Biomedicine. All themes address the role of evidence in relationship to acceptance of complementary therapies and correspond with three thought processes: critical thinking, relying on others for evidence, and reactionary thinking. CONCLUSION: Both scientific and anecdotal evidence informed CIM use in this context. Biomedical environments seeking to integrate CIM into pain treatment regimens will need to engage all relevant stakeholders in building education, clinical training, and research programs that are critically informed about the context and evidence for CIM.

A biocultural approach to psychiatric illnesses.

RATIONALE: As a species, humans are vulnerable to numerous mental disorders, including depression and schizophrenia. This susceptibility may be due to the evolution of our large, complex brains, or perhaps because these illnesses counterintuitively confer some adaptive advantage. Additionally, cultural and biological factors may contribute to susceptibility and variation in mental illness experience and expression. Taking a holistic perspective could strengthen our understanding of these illnesses in diverse cultural contexts. OBJECTIVES: This paper reviews some of these potential factors and contextualizes mental disorders within a biocultural framework. RESULTS: There is growing evidence that suggests cultural norms may influence inflammation, neurotransmitters, and neurobiology, as well as the illness experience. Specific examples include variation in schizophrenia delusions between countries, differences in links between inflammation and emotion between the United States and Japan, and differences in brain activity between Caucasian and Asian participants indicating that cultural values may moderate cognitive processes related to social cognition and interoception. CONCLUSIONS: Research agendas that are grounded in an appreciation of biocultural diversity as it relates to psychiatric illness represent key areas for truly interdisciplinary research that can result in culturally sensitive treatments and highlight possible biological variation affecting medical treatment.

Mental health care treatment seeking among African Americans and Caribbean Blacks: what is the role of religiosity/spirituality?

OBJECTIVES: As adults increase in age, the likelihood for using mental health care services decrease. Underutilization, expecially among racial/ethnic minorities such as African American and Caribbean Blacks, can result in a decrease in quality of life, as well as significant costs to families, employers, and health systems. METHODS: The study explored the differences in relationships between mental health care usage and strength of religious/spiritual beliefs between African American and Caribbean Black older adults (54 years or older) and adults (18-53 years) using data from the National Survey of American Life (NSAL). Descriptive statistics and logistic regression analyses were conducted using Stata version 13.1. RESULTS: Subjective ratings about the strength of religious/spiritual beliefs (OR = 1.26; 95 CI: 0.99, 1.61), age (OR = 0.62; 95 CI: 0.48, 0.81), and sex (OR = 1.59; 95 CI: 1.25, 2.02) were significantly associated with the odds of seeking mental health care. Additionally, persons living in the South were less likely to seek mental health care services (OR = 0.47; 95 CI: 0.37, 0.60). CONCLUSION: Strong religious/spiritual beliefs may promote mental health care usage. Future studies should examine the strength of religious/spiritual beliefs on mental health care usage among different demographic groups.

Examining Demographics, Prior Academic Performance, and United States Medical Licensing Examination Scores.

PURPOSE: To examine whether demographic differences exist in United States Medical Licensing Examination (USMLE) scores and the extent to which any differences are explained by students' prior academic achievement. METHOD: The authors completed hierarchical linear modeling of data for U.S. and Canadian allopathic and osteopathic medical graduates testing on USMLE Step 1 during or after 2010, and completing USMLE Step 3 by 2015. Main outcome measures were computer-based USMLE examinations: Step 1, Step 2 Clinical Knowledge, and Step 3. Test-taker characteristics included sex, self-identified race, U.S. citizenship status, English as a second language, and age at first Step 1 attempt. Covariates included composite Medical College Admission Test (MCAT) scores, undergraduate grade point average (GPA), and previous USMLE scores. RESULTS: A total of 45,154 examinees from 172 medical schools met the inclusion criteria. The sample was 67% white and 48% female; 3.7% non-U.S. citizens; and 7.4% with English as a second language. Hierarchical linear models examined demographic variables with and without covariates including MCAT scores and GPA. All Step examinations showed significant differences by gender after adding covariates, varying by Step. Racial differences were observed for each Step, attenuated by the addition of covariates. CONCLUSIONS: Demographic differences in USMLE performance were tempered by previous examination performance and undergraduate performance. Additional research is required to identify factors that contribute to demographic differences, can aid educators' identification of students who would benefit from assistance preparing for USMLE, and can assist residency program directors in assessing performance measures while meeting diversity goals.

The Association Between a Holistic Review in Admissions Workshop and the Diversity of Accepted Applicants and Students Matriculating to Medical School.

PURPOSE: The authors tested for an association between the Association of American Medical Colleges' holistic review in admissions (HRA) workshop and the compositional diversity of medical school accepted applicants and matriculants in schools that held workshops compared with those that did not. METHOD: The authors examined school-level data from 134 medical schools accredited by the Liaison Committee on Medical Education for the years 2006-2016 using information from the American Medical College Application Service. They used a fixed-effects regression to examine the within-school association between an HRA workshop and four measures of diversity: percent first-generation college student, percent black/African American, percent Hispanic, and overall level of racial/ethnic diversity as measured by a diversity index. RESULTS: For schools that held an HRA workshop, descriptive statistics showed higher mean values across all four measures of diversity for the post-HRA workshop period (the HRA implementation period) compared with the preworkshop period (accepted applicants: d = 0.34-0.79; matriculants: d = 0.29-0.73). Analyzing data for all schools, including those that did not hold a workshop, regression models showed that the HRA implementation period was associated with a significant and sustained increase in all four measures of diversity. These findings were consistent for both accepted applicants (P < .01) and matriculants (P < .01). CONCLUSIONS: The significant increases in all four measures of diversity following an HRA workshop support the conclusion that this workshop was associated with increased compositional diversity at the participating medical schools.

HIV and religion in HIV-infected Asians and their families: A qualitative study.

AIM: This paper examines HIV-infected Asian Americans' experiences with religion throughout the course of their illness and their family relationships. BACKGROUND: As the number of Asians in the United States continues to grow, health professionals are beginning notice obvious gaps of knowledge in caring for this population, including HIV-infected individuals. Little is known about the impact of religion and faith on Asian Americans with HIV and their families. The study focuses on the participants' reported experiences to understand the variety of roles religion can play in the progression of a highly stigmatized chronic disease. METHODS: An in-depth interview was conducted in San Francisco and New York City with 30 HIV-infected Asians. Narrative samples and summarized responses was used to highlight themes that emerged from the participants' anecdotes. Interpretive content analysis was employed. RESULTS: These groups were categorized as (a) those who did not adhere to any religion, (b) those of tenuous religious faith with conflicted feelings, and (c) those of strong religious faith with congruent beliefs. Within these three groups, various themes were synthesized from the members' perceptions and past experiences with religion. Within each group, participants displayed various stages of reconciliation with their current faith-related beliefs and escape the family stress from their religion practices. Each participant's story shown the vast range of human understanding and faith experiences including self-actualization, acculturation, and depression. CONCLUSIONS: This research provides new insight on the challenge of managing HIV-infected patients in a culturally and religiously appropriate manner.

Cultural factors associated with physical activity among U.S. adults: An integrative review.

AIM: The purpose of this integrative review is to identify the cultural factors associated with physical activity (PA) among United States (U.S.) adults. BACKGROUND: Physical inactivity is a significant public health problem that requires comprehensive community-based efforts. Cultural factors influence behavior and attitudes towards PA. Therefore, identifying the cultural factors is a key requirement for the planning of specific measures to enhance the level of PA and are more promising than campaigns aimed at the general population. This integrative review examined existing research on cultural factors influencing adult PA to inform the development of culturally adapted PA interventions in adults. METHODS: Literature searches were conducted in key scientific databases (PubMed, Cumulative Index to Nursing and Allied Health, and PsycINFO) using several key words related to both culture and PA. Fifteen peer-reviewed articles were identified, reviewed, synthesized, and critically analyzed. RESULTS: Eight major categories of cultural factors were identified: 1) collectivism and cultural identity; 2) religiosity; 3) cultural attitudes and gender norms in regards to PA; 4) cultural perspectives on health in regards to PA; 5) cultural expectations of familism and lack of time; 6) lack of role models and lack of motivation; 7) lack of culturally appropriate exercise facilities; and 8) cultural expectations of body image and physical appearance. CONCLUSIONS: Review findings emphasize the need for health promotion targeted toward improving cultural barriers to PA among U.S. Adults.

Rest Among African American Women: The Current State of the Science.

Effective health promotion among African American women requires knowledge and understanding of cultural influences and practices. This scoping review focused on rest, related concepts, and cultural perspectives and practices. We found a lack of conceptual distinction between fatigue and sleep and limited research on cultural meanings and practices of rest.

I Am an African American: Distinguishing Between African American and African Applicants in Medical School Admissions Matters.

Ignoring the diverse and rich cultures and histories of Africa and the African diaspora by applying the term African American to anyone of sub-Saharan African ancestry in medical school admissions does a disservice to applicants, medical schools, and the communities they serve. To determine how applicants can contribute to a diverse educational environment, admissions decisions must go beyond racial and ethnic self-reporting and recognize the diversity that applicants bring to their medical school. Using a holistic approach, institutions can fairly evaluate applicants and strategically fill their incoming classes. What each medical school is looking for based on its mission and how each student reflects that mission and enhances the educational environment should be revisited as each application is considered. Medical schools must adopt practices that strategically enroll applicants who help achieve their mission and better the communities they serve. The benefits of diversity are not achieved in a linear fashion but require a critical mass for each diverse group. Different strategies are needed to enhance the educational environment, address underrepresentation in medicine, and eliminate health disparities. If racial justice and health equity are to be realized, diversity policies need to recognize the differences between African and Afro Caribbean immigrants and African Americans.In this Perspective, the author argues for distinguishing between these groups in medical school admissions. He explores the differences in their history, culture, and experiences and demonstrates their uniqueness. He concludes by discussing diversity in medicine and offering suggestions for considering diversity in medical school admissions.

Humanizing folk devils using ethnography.

The sociological concepts of the "moral panic" and the deviant "folk devil" apply to the drug panics in the United States over methamphetamine, heroin, and crack cocaine. Mothers or pregnant women who smoke crack cocaine, and their babies, are assigned exaggerated "demonic" attributes that result in stigma and societal rejection. Otherwise, ethnographic studies of drug users demonstrate realities that are other than what might be considered were one to merely look at their use and the consequences. These considerations are examined with respect to the image of folk devils, methadone program attendees, smokers of "blunts," opium den habitués, and others grouped together as negative influences as a result of their drug habits.

Claim More™: Empowering African American Women to Make Healthy Choices.

Diabetes is a serious issue for African American women. The purpose of this project was to develop and test the feasibility of a culturally appropriate and faith-based healthy eating program for African American women at risk for developing diabetes. At total of 30 women from two churches completed a 12-week, faith-based program using a community-based approach with lay health educators in the church setting. Participants set healthy eating goals, attended weekly education classes, and received daily text messaging reminders related to their goals. Outcomes included high levels of social support, frequent engagement with the program, and improved healthy eating. This program demonstrated the ability to target African American women at risk for diabetes and engage them in a health-related program.

Longitudinal effects of religious involvement on religious coping and health behaviors in a national sample of African Americans.

Many studies have examined associations between religious involvement and health, linking various dimensions of religion with a range of physical health outcomes and often hypothesizing influences on health behaviors. However, far fewer studies have examined explanatory mechanisms of the religion-health connection, and most have overwhelmingly relied on cross-sectional analyses. Given the relatively high levels of religious involvement among African Americans and the important role that religious coping styles may play in health, the present study tested a longitudinal model of religious coping as a potential mediator of a multidimensional religious involvement construct (beliefs; behaviors) on multiple health behaviors (e.g., diet, physical activity, alcohol use, cancer screening). A national probability sample of African Americans was enrolled in the RHIAA (Religion and Health In African Americans) study and three waves of telephone interviews were conducted over a 5-year period (N = 565). Measurement models were fit followed by longitudinal structural models. Positive religious coping decreased modestly over time in the sample, but these reductions were attenuated for participants with stronger religious beliefs and behaviors. Decreases in negative religious coping were negligible and were not associated with either religious beliefs or religious behaviors. Religious coping was not associated with change in any of the health behaviors over time, precluding the possibility of a longitudinal mediational effect. Thus, mediation observed in previous cross-sectional analyses was not confirmed in this more rigorous longitudinal model over a 5-year period. However, findings do point to the role that religious beliefs have in protecting against declines in positive religious coping over time, which may have implications for pastoral counseling and other faith-based interventions.

Patterns of Regional Lymphadenectomy for Clinically Node-negative Patients With Penile Carcinoma: Analysis From the National Cancer Database From 1998 to 2012.

PURPOSE: Evidence supports upfront regional lymphadenectomy (rND) when primary penile tumors exhibit high-risk features and negative inguinal adenopathy (cN0). We sought to analyze trends in the utilization of early rND as well as assess factors associated with its use and survival outcomes using a nationwide cancer registry database. PATIENT AND METHODS: The National Cancer Database was queried for patients with clinically nonmetastatic penile carcinoma and available nodal status who underwent rND from 1998 to 2012. Temporal trends in the utilization of early rND for those with cN0 disease were analyzed, and a multivariable logistic regression model was used to identify predictors for receiving rND. Survival analysis based on rND status was performed using the Kaplan-Meier method and Cox proportional hazard regression. RESULTS: From 1919 patients with available clinicopathologic variables, performance of early rND was documented in 377 (19.6%) patients with an increase in utilization over time (P = .001). The increase was driven by academic and comprehensive cancer programs compared with community programs (P < .001). Positive predictors were treatment facility, clinical tumor stage, and grade (all P < .05). African American patients (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.33-0.86; P = .01) and those aged > 75 years (OR, 0.42; 95% CI, 0.26-0.68; P < .001) were significantly less likely to receive rND. Early rND was associated with improved overall survival (hazard ratio [HR], 0.67; 95% CI, 0.52-0.87; P = .003). CONCLUSION: There was increased use of early lymphadenectomy for patients with cN0 penile cancer driven by comprehensive and academic cancer programs. The study demonstrated demographic and socioeconomic differences that can help identify barriers to care for patients with penile cancer in the United States.
