RESUMEN
Disproportionate exposure to adverse neighborhood conditions and greater discrimination may contribute to health disparities among African Americans (AAs). We examined whether adverse neighborhood conditions, alone or in conjunction with discrimination, associate with shorter leukocyte telomere length among a predominantly AA cohort. The sample included 200 residents from two low-income neighborhoods (96% AA; mean age = 67 years). Perceived neighborhood conditions and discrimination were surveyed in 2018, and objective neighborhood conditions (total crime rate, neighborhood walkability, ambient air pollution (PM2.5, black carbon)) were collected in 2017/2018. Relative telomere length (T/S; ratio of telomeric DNA to a single-gene copy) was assessed from blood samples. Linear regression models estimated the main effects of each neighborhood condition and discrimination and their interactions on the T/S ratio. Less walkable neighborhoods were associated with shorter telomeres. Higher air pollution (PM2.5) was associated with shorter telomeres among those experiencing greater discrimination. Findings highlight the importance of understanding the intersecting influences of historic and contemporary sources of systemic racism and how they contribute to accelerated aging among adults.

Homeless young adults are at risk for alcohol and other drug (AOD) use and risky sexual behavior. Interventions are needed to help these young people reduce their risky behavior, but this population is often difficult to engage and retain in services. We offered a four-session AOD and risky sex reduction program to 100 participants and examined if retention in the program was predicted by a number of factors: demographics, homelessness severity, other service use, AOD behaviors, mental health symptoms, sexual risk behaviors, and readiness to change AOD and condom use. Nearly half (48%) of participants completed all sessions. In bivariate analyses, participants were significantly less likely to be retained in the program if they had slept outdoors in the past month, engaged in more alcohol and marijuana use, experienced more alcohol-related consequences, and received the program in an urban drop-in center (as opposed to a drop-in center near the beach). When controlling for all significant bivariate relationships, only sleeping outdoors and receipt of the program in the urban setting predicted fewer sessions completed. The most endorsed reasons for program non-completion were being too busy to attend and inconvenient day/time of the program. Findings can help outreach staff and researchers better prepare methods to engage higher risk homeless youth and retain them in services. Finding unique ways to help youth overcome barriers related to location of services appears especially necessary, perhaps by bringing services to youth where they temporarily reside or offering meaningful incentives for program attendance.

BACKGROUND: Errors in reported height and weight raise concerns about body mass index (BMI) and obesity estimates obtained from self or proxy reports. Researchers have corrected BMI using linear statistical models, primarily with adult samples. We compared the accuracy of BMI correction in children for models that included child or parent reports versus both reports, and models that separately predicted height and weight compared to a single model for BMI. METHODS: Height and weight from child reports, parent reports, and objective measurements for 475 children participating in the Military Teenagers' Environment, Exercise and Nutrition Study were analyzed. Two approaches were evaluated: (1) separate linear correction models for height and weight versus (2) a single linear correction model for BMI. Each approach considered models for height, weight, or BMI with child reports, parent reports, or both reports, respectively, as predictors, stratified by gender. Prediction accuracy was computed using leave-one-out validation. Models were compared using root mean squared error for BMI, and sensitivity and specificity for overweight and obesity indicators. RESULTS: Models that included both reports provided the best fit relative to a model using either set of reports, with adjusted R(2) of height, weight, and BMI models ranging from 67.1 to 87.6 % in males, and 69.2 to 88.3 % in females. Estimates of BMI from separate models for height and weight had the least prediction error, relative to those derived from a single model for BMI or from uncorrected (child or parent) reports. Cross-validated Root Mean Squared Error (RMSEs) preferred a model that included only parent reports among males and females, compared to models with only child reports or both reports. When assessing sensitivity (true positive) for obesity and overweight/obesity, the results varied by gender and outcomes. Specificity (true negative) was similarly high for all models. CONCLUSION: Objective measurements are more accurate than self- or proxy-reports of BMI. In situations where objective measurement is infeasible, an approach that combines collecting a validation sub-sample including multiple reports of children's height and weight, with estimation of BMI correction models maybe a cost-effective and practical solution. Correction models generate BMI estimates that are closer to objective measurements than reports.
RESUMEN
HIV-related stigma and mistrust contribute to HIV disparities. Addressing stigma with faith partners may be effective, but few church-based stigma reduction interventions have been tested. We implemented a pilot intervention with 3 Latino and 2 African American churches (4 in matched pairs) in high HIV prevalence areas of Los Angeles County to reduce HIV stigma and mistrust and increase HIV testing. The intervention included HIV education and peer leader workshops, pastor-delivered sermons on HIV with imagined contact scenarios, and HIV testing events. We surveyed congregants at baseline and 6 month follow-up (n = 1235) and found statistically significant (p < 0.05) reductions in HIV stigma and mistrust in the Latino intervention churches but not in the African American intervention church nor overall across matched African American and Latino pairs. However, within matched pairs, intervention churches had much higher rates of HIV testing (p < 0.001). Stigma reduction and HIV testing may have synergistic effects in community settings.

Community-based human immunodeficiency virus (HIV) testing at religious congregations has been proposed as a potentially effective way to increase screening among disproportionately affected populations, such as those self-identifying as African American and Latino. Although congregations may provide reach into these communities, the extent to which church-based HIV testing alleviates access barriers, identifies new cases, and reaches people at increased risk for HIV is not well documented. We examined the results of an HIV testing program that was conducted as part of a larger intervention aimed at reducing HIV stigma at five churches in Los Angeles County, California, in 2011-2012. HIV screening identified one positive result in 323 tests but reached a substantial proportion of people who had not been tested before, including many who lacked health insurance. Although this approach may not be an efficient way to identify cases of previously unknown HIV infection, it could help achieve universal testing goals.

Substance use patterns among Latinos likely reflect changes in attitudes resulting from acculturation, but little is known about Latinos' attitudes regarding drug addiction. We surveyed a church-based sample of Latinos and African Americans (N = 1,235) about attitudes toward drug addiction and socio-demographics. Linear regression models compared Latino subgroups with African-Americans. In adjusted models, Latinos had significantly higher drug addiction stigma scores compared to African Americans across all subgroups (US-born Latinos, ß = 0.22, p < .05; foreign-born Latinos with high English proficiency, ß = 0.30, p < .05; and foreign-born Latinos with low English proficiency, ß = 0.49, p < .001). Additionally, Latinos with low English proficiency had significantly higher mean levels of drug use stigma compared Latinos with high proficiency (both foreign-born and US-born). In this church-affiliated sample, Latinos' drug addiction stigma decreases with acculturation, but remains higher among the most acculturated Latinos compared to African-Americans. These attitudes may pose a barrier to treatment for Latino drug users.

OBJECTIVE: Little smoking research in the past 20years includes persons 50 and older; herein we describe patterns of clinician cessation advice to US seniors, including variation by Medicare beneficiary characteristics. METHOD: In 2012-4, we analyzed 2010 Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey data from Medicare beneficiaries over age 64 (n=346,674). We estimated smoking rates and the proportion of smokers whose clinicians encouraged cessation. RESULTS: 12% of male and 8% of female respondents aged 65 and older smoke. The rate decreases with age (14% of 65-69, 3% of 85+) and education (12-15% with no high school degree, 5-6% with BA+). Rates are highest among American Indian/Alaskan Native (16%), multiracial (14%), and African-American (13%) seniors, and in the Southeast (14%). Only 51% of smokers say they receive cessation advice "always" or "usually" at doctor visits, with advice more often given to the young, those in low-smoking regions, Asians, and women. For all results cited p<0.05. CONCLUSIONS: Smoking cessation advice to seniors is variable. Providers may focus on groups or areas in which smoking is less common or when they are most comfortable giving advice. More consistent interventions are needed, including cessation advice from clinicians.

Faith-based organizations can be key settings in which to reach African Americans and Latinos for HIV prevention, but little is known regarding factors that predict congregants' HIV testing behaviors. We examined the extent to which sociodemographic factors, HIV-related cues to action (e.g., knowing someone who is HIV-positive), and the social climate surrounding HIV (stigma toward a hypothetical HIV-positive congregant, HIV-related discussions at church about abstinence, condoms, and testing) were associated with willingness to be tested in church and with ever having been tested among 1211 African American and Latino congregants. Multivariate analyses indicated that congregants were more open to church-based testing if they were younger and had discussed condoms at church. They were less open if they expressed stigmatizing attitudes toward a hypothetical congregant. Foreign-born Latinos with low English proficiency were more willing to be tested at church than were African Americans. Congregants were more likely to have ever been tested if they were younger, African American, female, or married; if they knew someone who was HIV-positive; and if they had discussed testing and condoms at church. They were less likely if they had discussed abstinence. Open dialogue around HIV may activate congregants to be more receptive to church-based prevention.

Sleep disturbances are a common reaction to stress and are linked to a host of physical and mental health problems. Given the unprecedented demands placed on U.S. military forces since 2001, there has been growing concern about the prevalence and consequences of sleep problems for servicemembers. Sleep problems often follow a chronic course, persisting long after servicemembers return home from combat deployments, with consequences for their reintegration and the readiness and resiliency of the force. Therefore, it is critical to understand the role of sleep problems in servicemembers' health and functioning and the policies and programs available to promote healthy sleep. This study provides the first comprehensive review of sleep-related policies and programs across the U.S. Department of Defense (DoD), along with a set of actionable recommendations for DoD, commanders, researchers, and medical professionals who treat U.S. servicemembers. The two-year multimethod study also examined the rates and correlates of sleep problems among post-deployed servicemembers, finding negative effects on mental health, daytime impairment, and perceived operational readiness. The research reviewed evidence-based interventions to treat sleep disturbances among servicemembers and veterans and exposed several individual- and system-level barriers to achieving healthy sleep. Implementing evidence-based treatments is just one step toward improving sleep across the force; as the research recommendations highlight, it is equally important that policies and programs also focus on preventing sleep problems and their consequences.
RESUMEN
This study evaluated how the Perfecting Patient Care (PPC) University, a quality improvement (QI) training program for health care leaders and clinicians, affected the ability of organizations to improve the health care they provide. This training program teaches improvement methods based on Lean concepts and principles of the Toyota Production System and is offered in several formats. A retrospective evaluation was performed that gathered data on training, other process factors, and outcomes after staff completed the PPC training. A majority of respondents reported gaining QI competencies and cultural achievements from the training. Organizations had high average scores for the success measures of "outcomes improved" and "sustainable monitoring" but lower scores for diffusion of QI efforts. Total training dosage was significantly associated with the measures of QI success. This evaluation provides evidence that organizations gained the PPC competencies and cultural achievements and that training dosage is a driver of QI success.

BACKGROUND: The lack of a standard measure of quality improvement (QI) success and the use of subjective or self-reported measures of QI success has constrained efforts to formally evaluate QI programs and to understand how the various contextual factors impact QI success. OBJECTIVES: The objective of this study was to assess how best to measure "QI success" by comparing self-reported and externally rated measures of QI success. RESEARCH DESIGN: We performed a retrospective evaluation that analyzed data on different measures of QI success for organizations after their staff completed the QI training. SUBJECTS: The sample included 30 organizations whose staff had received QI training during 2006-2008, and who had used this training to carry out at least some subsequent QI initiative in their organizations. MEASURES: We developed 2 measures of self-reported QI success based on survey responses and 4 externally rated measures of QI success based on outcome data provided by the participating organizations in addition to qualitative data generated from the interviews. RESULTS: We found some variation in the mean scores of the different QI success measures and only moderate to small correlations between the self-report and externally rated QI measures. CONCLUSIONS: This study confirms that there are important differences between self-reported and externally rated measures of QI success and provides researchers with a methodology and criteria to externally rate measures of QI success.
