    Open AccessChris Gillette, Joachim Ostermann et al.ARTICLEMedical Education Online2026

    Optimizing the geographic allocation of health care providers has the potential to improve health care access and health outcomes for rural populations. To inform the design of a discrete choice experiment (DCE) survey to elicit health professions trainees' preferences for rural practice, this formative research aimed to: (1) elicit factors that influence job selection among health profession trainees, including medical residents physician assist…

  • Preferences of health professions learners

    Open AccessSarah O'Neal, Natalie Smith et al.ARTICLEMedical Education Online2026

    While discrete choice experiments (DCE), have increasingly been used in the medical literature, little is known about the use of these methods for eliciting preferences from and about students and trainees in health professions. The objectives of this scoping review are to (1) describe the extent to which DCEs have been used in health professions' education, (2) identify which health professionals have been studied, and (3) identify thematic area…

  • What drives advanced practice nurses to stay in rural America? Insights from the 2022 National Survey of Registered Nurses

    Open AccessEsita Patel, Chris Gillette et al.ARTICLEThe Journal of Rural Health2025

    PURPOSE: Recruiting and retaining a robust rural health care workforce is critical to advancing health outcomes in rural communities. Although increasing the rural provider workforce has been a policy focus for decades, rural access continues to worsen. Using a strengths-based approach, we identify factors that influence the decisions of advanced practice registered nurses (APRNs) to leave or stay in their jobs. METHODS: Secondary analysis of dat…

  • Rural‐urban disparities in human papillomavirus vaccination

    Open AccessLavanya Vasudevan, Yunfei Wang et al.ARTICLEThe Journal of Rural Health2025

    BACKGROUND: Rural adolescents in the United States lag behind their urban counterparts in the uptake of the human papillomavirus (HPV) vaccine. However, a systematic assessment of factors associated with rural-urban disparities in HPV vaccination coverage to inform potential vaccination promotion interventions is lacking in the literature. Prioritizing HPV vaccination for rural adolescents is necessary for increasing overall HPV vaccination cover…

  • A comparison of assessment tools for childcare centers in high vs. low resource settings

    Open AccessHy V Huynh, Eve S Puffer et al.ARTICLEFrontiers in Public Health2024

    Studies suggest issues may arise when using childcare setting assessment tools designed for high-resource settings in low-resource settings to assess and improve the quality of care, including placing disproportionate weight on features of the childcare environment that may not be available or culturally appropriate within the low-resource context. This study compares a novel assessment tool developed in and for low-income and low-resource settin…

  • Predictors of prior HIV testing and acceptance of a community-based HIV test offer among male bar patrons in northern Tanzania

    Open AccessDeng B Madut, Preeti Manavalan et al.ARTICLEPLOS Global Public Health2024

    Community-based HIV testing offers an alternative approach to encourage HIV testing among men in sub-Saharan Africa. In this study, we evaluated a community-based HIV testing strategy targeting male bar patrons in northern Tanzania to assess factors predictive of prior HIV testing and factors predictive of accepting a real-time HIV test offer. Participants completed a detailed survey and were offered HIV testing upon survey completion. Poisson re…

  • Stigmatizing clinical setting erodes physician-patient interaction quality for sexual minority men through perceived HIV stigma and HIV infection concerns in Zambia

    Abhishek Aggarwal, Ran Zhang et al.ARTICLEAIDS Care2024

    This study investigated whether perceived HIV stigma and HIV infection concerns among healthcare providers (HCPs) mediate the association between stigmatizing clinical setting and their interaction quality with sexual minority men (SMM) patients in Zambia. In 2021, a cross-sectional survey was conducted with 91 HCPs offering HIV-related services to SMM in Zambia. Path analysis was conducted to examine the potential mediation effect of “perceived …

  • Divergent preferences for enhanced HIV testing options among high-risk populations in northern Tanzania

    Joachim Ostermann, Bernard Njau et al.ARTICLEAIDS Care2023

    To achieve the UNAIDS target of diagnosing 95% of all persons living with HIV, enhanced HIV testing services with greater attractional value need to be developed and implemented. We conducted a discrete choice experiment (DCE) to quantify preferences for enhanced HIV testing features across two high-risk populations in the Kilimanjaro Region in northern Tanzania. We designed and fielded a survey with 12 choice tasks to systematically recruited fe…

  • Physician–Patient Interaction Quality Mediates the Association Between HIV-Related Stigma and HIV-Prevention Behaviors Among Sexual Minority Men in Zambia

    Open AccessAbhishek Aggarwal, Ran Zhang et al.ARTICLEAIDS and Behavior2023

  • Fraternity as Natural Being

    Open AccessJoachim OstermannARTICLEReligions2022Referencias: 1

    In a scientifically understood world, making sense of natural being is a challenge. This is particularly acute when knowledge of nature impinges on human autonomy. I present two examples: The legitimacy of opposing abortion on account of "potential life", and the legitimacy of mandatory vaccination during a pandemic. I then explore the concept of fraternity in the writings of St. Francis at the example of the Rule of 1221 and the Canticle of Crea…

  • Increasing the Uptake of HIV Testing among Men in Tanzania

    Open AccessDeng B Madut, Preeti Manavalan et al.ARTICLEAIDS and Behavior2021

    Open AccessSayward E Harrison, Valerie Yelverton et al.ARTICLEAmerican Journal of Health Behavior2021

    Objectives: Understanding the relationship between human papillomavirus (HPV) knowledge and vaccination behavior is important to inform public health interventions, yet few validated HPV knowledge scales exist. This study describes development of the Human Papillomavirus Knowledge Questionnaire (HPV-KQ) and its validation with parents residing in the southern United States (US). Methods: Drawing on previously published measures, we developed the …

  • Parental concerns and uptake of childhood vaccines in rural Tanzania – a mixed methods study

    Open AccessLavanya Vasudevan, Joy Noel Baumgartner et al.ARTICLEBMC Public Health2020

    Findings from our cross-sectional survey indicate the presence of vaccination delays and maternal concerns related to childhood vaccines in Tanzania. In FGDs, mothers raised issues related to convenience more often than issues related to vaccine confidence or complacency. Further research is necessary to understand how these issues may contribute to the emergence and persistence of vaccine hesitancy and to identify effective mitigation strategies

  • Civic engagement among orphans and non-orphans in five low- and middle-income countries

    Open AccessChristine L Gray, Brian W Pence et al.ARTICLEGlobalization and Health2016

    BACKGROUND: Communities and nations seeking to foster social responsibility in their youth are interested in understanding factors that predict and promote youth involvement in public activities. Orphans and separated children (OSC) are a vulnerable population whose numbers are increasing, particularly in resource-poor settings. Understanding whether and how OSC are engaged in civic activities is important for community and world leaders who need…

  • Potentially traumatic experiences and sexual health among orphaned and separated adolescents in five low- and middle-income countries

    Open AccessChristine L Gray, Kathryn Whetten et al.ARTICLEAIDS Care2016

    Orphans and separated children (OSC) are a vulnerable population whose numbers are increasing, particularly in sub-Saharan Africa and Asia. Over 153 million children worldwide have lost one or both parents, including 17 million orphaned by AIDS, and millions more have been separated from their parents. As younger orphans enter adolescence, their sexual health and HIV-related risk behaviors become key considerations for their overall health. Impor…

  • One size does not fit all

    Joachim Ostermann, Bernard Njau et al.ARTICLEAIDS Care2015

    In order to maximize the effectiveness of "Seek, Test, and Treat" strategies for curbing the HIV epidemic, new approaches are needed to increase the uptake of HIV testing services, particularly among high-risk groups. Low HIV testing rates among such groups suggest that current testing services may not align well with the testing preferences of these populations. Female bar workers and male mountain porters have been identified as two important h…

  • HIV serostatus disclosure in the treatment cascade

    Joachim Ostermann, Brian W Pence et al.ARTICLEAIDS Care2015

    HIV serostatus disclosure plays an important role in HIV transmission risk reduction and is positively associated with HIV medication adherence and treatment outcomes. However, to date, no study has quantified the role of disclosure across the HIV treatment cascade, particularly in Sub-Saharan Africa. We used data from a cohort of HIV-infected adults in Northern Tanzania to describe associations between disclosure and engagement and retention in …

  • Gender (in) differences in prevalence and incidence of traumatic experiences among orphaned and separated children living in five low- and middle-income countries

    Open AccessChristine L Gray, Brian W Pence et al.ARTICLECambridge Prisms Global Mental…2015

    Prevalence and annual incidence of PTEs were high among OSC in general, but gender-specific estimates were comparable. Although support services and prevention programs are essential for female OSC, programs for male OSC are equally important

  • Adverse childhood experiences, psychosocial well-being and cognitive development among orphans and abandoned children in five low income countries

    Open AccessThe Positive Outcomes for Orphans Research Team, Maya Escueta et al.ARTICLEBMC International Health and…2014

    BACKGROUND: Development policymakers and child-care service providers are committed to improving the educational opportunities of the 153 million orphans worldwide. Nevertheless, the relationship between orphanhood and education outcomes is not well understood. Varying factors associated with differential educational attainment leave policymakers uncertain where to intervene. This study examines the relationship between psychosocial well-being an…

  • Treatment retention and care transitions during and after the scale-up of HIV care and treatment in Northern Tanzania

    Joachim Ostermann, Aris Sukamto et al.ARTICLEAIDS Care2014

    Decentralization of HIV care is promoted to improve access to antiretroviral therapy in sub-Saharan Africa. This study describes care transitions among HIV-infected persons in Northern Tanzania during a period of rapid decentralization of HIV care and treatment centers (CTCs) from hospitals to local health centers. Between November 2008 and June 2009, 492 HIV-infected patients in established care at two referral hospitals in Moshi, Tanzania, and …

  • Low rates of child testing for HIV persist in a high-risk area of East Africa

    Kelsey O’donnell, Karen O’donnell et al.ARTICLEAIDS Care2014

    Children in low- and middle-income countries (LMIC) are the least touched by recent successes in the diagnosis and treatment of HIV/AIDS globally. Early treatment is essential for a child's longer and higher quality of life; however, by 2011, only a small proportion of HIV-seropositive children in LMIC countries were receiving treatment, in part because of persisting low rates of diagnosis. This study of the prevalence and characteristics of chil…

  • HIV testing preferences in Tanzania

    Open AccessBernard Njau, Joachim Ostermann et al.ARTICLEBMC Public Health2014

    Testing decisions appear to be influenced by an array of often inter-linked factors across multiple domains, including quality, confidentiality, and accessibility; perceptions of these factors varied greatly across participants and across available testing options. HCT interventions that jointly target barriers spanning the three domains have the potential to increase uptake of HIV testing and deserve further exploration

  • Child and caregiver concordance of potentially traumatic events experienced by orphaned and abandoned children

    Divya Guru Rajan, Kristen Shirey et al.ARTICLEVulnerable Children and Youth…2013Citada por: 1Referencias: 1

    Exposure to trauma is associated with significant emotional and behavioral difficulties among children (Perepletchikova & Kaufman, 2010). Overall, reports of trauma and violence experienced by children are discrepant from those of their caregivers (Lewis et al., 2012). Even less is known about the extent of concordance between orphans and their caregivers. This study examines the correlates of concordance in reported traumatic experiences between…

  • Perceived acceptability of home-based couples voluntary HIV counseling and testing in Northern Tanzania

    Bernard Njau, Melissa H Watts et al.ARTICLEAIDS Care2012

    It is estimated that 5.6% of the Tanzanian population ages 15-49 are infected with HIV, but only 30% of adults have ever had an HIV test. Couples' testing has proven to increase testing coverage and introduce HIV prevention, but barriers include access to testing services and unequal gender dynamics in relationships. Innovative approaches are needed to address barriers to couple's testing and increase uptake of HIV testing. Using qualitative data…

  • Changes in HIV risk behavior and seroincidence among clients presenting for repeat HIV counseling and testing in Moshi, Tanzania

    Suzanne P Fiorillo, Suzanne Fiorillo et al.ARTICLEAIDS Care2012

    While HIV counseling and testing (HCT) has been considered an HIV preventive measure in Africa, data are limited describing behavior changes following HCT. This study evaluated behavior changes and estimated HIV seroincidence rate among returning HCT clients. Repeat and one-time testing clients receiving HCT services in Moshi, Tanzania were identified. Information about sociodemographic characteristics, HIV-related behaviors and testing reasons w…
