Socioeconomic Determinants Of Health Disparities By Race And Ethnicity: The Mediating Role Of Social, Psychological And Behavioral Factors, Amanuel Zimam Melekin

Dissertations and Theses

Socioeconomic status (SES) is inversely related to health status. Disparities in health status among races and ethnic groups are partly attributable to differences in SES, but the indirect pathways by which SES may influence health status are not widely studied.

Using the Health and Retirement Study (HRS) data, this dissertation examined the pathways by which SES, via social, psychological, and behavioral factors predicted physical impairment and overnight hospitalization, and asked whether these indirect relationships differed by race/ethnicity. The HRS is a nationally representative multistage area probability sample administered biennially to respondents over the age of 51 and their spouses. Data …

C-Safe: A Computer-Delivered Sexual Health Promotion Program For Latinas, Charles H. Klein, Tamara Kuhn, Midori Altamirano, Carmela Lomonaco

Anthropology Faculty Publications and Presentations

This article describes the development and evaluation of C-SAFE (Sexual Awareness for Everyone), a computer-delivered sexual health promotion program for Latinas. We first describe the process of adapting an evidence-based, group-level intervention into an individually administered computer-delivered program. We then present the methods and results of a randomized control trial with 321 Latinas in California and Florida to test C-SAFE's preliminary efficacy in reducing sexual health risk. We found no statistically significant differences between the two conditions at a six-month follow-up in terms of sexual behaviors or attitudes toward sexually transmitted infections and condoms, although C-SAFE women reported fewer days …

An Item-Response Theory Approach To Safety Climate Measurement: The Liberty Mutual Safety Climate Short Scales, Yueng-Hsiang Huanga, Jin Lee, Zhuo Chen, Mackenna Laine Perry, Janelle H. Chung, Mo Wang

Psychology Faculty Publications and Presentations

Zohar and Luria’s (2005) safety climate (SC) scale, measuring organization- and group- level SC each with 16 items, is widely used in research and practice. To improve the utility of the SC scale, we shortened the original full-length SC scales. Item response theory (IRT) analysis was conducted using a sample of 29,179 frontline workers from various industries. Based on graded response models, we shortened the original scales in two ways: (1) selecting items with above-average discriminating ability (i.e. offering more than 6.25% of the original total scale information), resulting in 8-item organization-level and 11-item group-level SC scales; and (2) selecting …

Brief Report: Medication Sharing Is Rare Among African Hiv-1 Serodiscordant Couples Enrolled In An Efficacy Trial Of Oral Pre-Exposure Prophylaxis (Prep) For Hiv-1 Prevention, Kerry A. Thomson, Jessica Haberer, Mark A. Marzinke, Andrew Mujugira, Craig Hendrix, Connie Celum, Patrick Ndase, Alan Ronald, David Bangsberg, Jared Baeten

OHSU-PSU School of Public Health Faculty Publications and Presentations

Sharing of pre-exposure prophylaxis (PrEP) medications is a concern for PrEP implementation. For HIV-1 serodiscordant couples, sharing may undermine the HIV-1 prevention benefit and also cause antiretroviral resistance if taken by HIV-1 infected partners. Within a PrEP efficacy trial among HIV-1 serodiscordant couples, we assessed the occurrence of PrEP sharing by self-report and plasma tenofovir concentrations in HIV-1 infected partners. PrEP sharing was self-reported at < 0.01% of visits, and 0% -1.6% of randomly selected and 0% of purposively selected specimens from HIV-1 infected participants had detectable tenofovir concentrations (median: 66.5 ng/mL, range: 1.3-292 ng/mL). PrEP sharing within HIV-1 serodiscordant couples was extremely rare.

Foundational Knowledge And Other Predictors Of Commitment To Trauma-Informed Care, Stephanie Anne Sundborg

Dissertations and Theses

Trauma-informed care (TIC) is an approach to service delivery based on the understanding of the prevalence of psychological trauma among service users, knowledge about the impact trauma has on engagement to services, and recognition that service settings can be re-traumatizing. For more than a decade, momentum has been building on this topic. Practitioners are pursuing the knowledge and skills needed to implement trauma-informed service delivery, while organizations are building infrastructure and processes aimed at supporting this approach. Disciplines across many human service sectors are eager to incorporate TIC into policy and practice. Despite this enthusiasm, implementation efforts are slow. Acquiring …

Evaluating Knowledge Of Developmental Disabilities Among Wic Participants, Carolina Regalado Murillo, Katharine Zuckerman, Alison Chavez, Julie A. Reeder

Student Research Symposium

OHSU-PSU School of Public Health Faculty Publications and Presentations

Aims—Among older American Indian women with type 2 diabetes (T2DM), we examined the association between mental health and T2DM control and if social support modifies the association.

Methods—Survey data were linked to T2DM medical record information. Mental health measures were the Center for Epidemiologic Studies – Depression Scale and the National Anxiety Disorders Screening Day instrument. T2DM control was all HbA1c values taken post mental health measures.

Results—There was not a significant association between depressive symptomatology and higher HbA1c although increased depressive symptomatology was associated with higher HbA1c values among participants with low social support. There was a significant association …

Each Medium Tells A Different Story: The Effect Of Message Channel On Narrative Persuasion, Nathan Walter, Sheila T. Murphy, Lauren B. Frank, Lourdes Baezconde-Garbanati

Communication Faculty Publications and Presentations

Limited attention has been given to the medium of story presentation in this process of narrative persuasion. The present study (N = 243) fills this gap by directly comparing narrative involvement across print and audiovisual versions of the same cervical cancer-related story. The mediation analysis revealed that exposure to an audiovisual narrative was associated with higher levels of cognitive and emotional involvement than exposure to the exact same narrative in its printed form. Yet the higher levels of transportation in the audiovisual condition came at a price of enhancing psychological reactance, eliminating the relative advantage of the film narrative.

Associations Between Prescribed Chinese Herbal Medicine And Risk Of Hepatocellular Carcinoma In Patients With Chronic Hepatitis B: A Nationwide Population-Based Cohort Study, Tzung-Yi Tsai, Hanoch Livneh, Tsung-Hsing Hung, I-Hsin Lin, Ming-Chi Lu, Chia-Chou Yeh

Counselor Education Faculty Publications and Presentations

Objective: Patients with chronic hepatitis B (CHB) are reported to exhibit higher risk of subsequent hepatocellular carcinoma (HCC). However, it remains unclear if Chinese herbal medicine (CHM), an important category of traditional Chinese medicine (TCM), may lower HCC risk in this population. So this study aimed to investigate the effects of CHM on HCC risk among patients with CHB.

Methods: This cohort study used the Taiwanese National Health Insurance Research Database to identify 21,020 newly diagnosed patients with CHB from 1998 to 2007. Among them, 8640 received CHM products after CHB onset (CHM users), and the remaining 12,380 patients were …

The Effects Of Frequency Of Social Interaction, Social Cohesion, Age, And The Built Environment On Walking, Gretchen Allison Luhr

Dissertations and Theses

The purpose of this dissertation was to explore, through a social ecological framework, the multifaceted effects of the neighborhood environment by investigating how dimensions of both the built environment and the neighborhood social context may interact to influence walking. Aesthetics, land use mix, crime, and pedestrian infrastructure were considered with respect to built environment walkability, and the neighborhood social context was conceptualized using measures of both social cohesion and social interaction with neighbors. This research used data from an Environmental Protection Agency (EPA)-funded study of 748 adults (18 years of age and older) residing in the Lents neighborhood in Portland, …

Phillips, Valentina Cambiano, Fumiyo Nakagawa, Loveleen Bansi-Matharu, Papa Salif Sow, Peter Ehrenkranz, Deborah Ford, Owen Mugurungi, Tsitsi Apollo, Joseph Murungu, David R. Bangsberg, Paul Revill

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background -Interventions based around objective measurement of adherence to antiretroviral drugs for HIV have potential to improve adherence and to enable differentiation of care such that clinical visits are reduced in those with high adherence. It would be useful to understand the approximate upper limit of cost that could be considered for such interventions of a given effectiveness in order to be cost effective. Such information can guide whether to implement an intervention in the light of a trial showing a certain effectiveness and cost.

Methods - An individual-based model, calibrated to Zimbabwe, which incorporates effects of adherence and resistance …

Real Talk: Developing A Computer-Delivered Sexual Health Program For Black Men Who Have Sex With Men, Charles H. Klein, Carmela Lomonaco

Anthropology Faculty Publications and Presentations

HIV disproportionately affects Black men who have sex with men (MSM), yet there are few evidence-based programs that respond to the diverse realities of Black MSM communities. This article examines the development of Real Talk, a new harm reduction-based, sexual health intervention for Black MSM. We first analyze the key themes from our formative research: (1) stigma, discrimination, and intersectionalities in the lives of Black MSM, (2) the importance of safe spaces and community provided by health promotion programs, and (3) moving beyond condoms in sexual health messaging. We then describe our agile design product development process and present an …

A Framework To Address Challenges In Communicating The Developmental Origins Of Health And Disease, Liana Winett, Lawrence Wallack, Dawn M. Richardson, Janne Boone-Heinonen, Lynne C. Messer

OHSU-PSU School of Public Health Faculty Publications and Presentations

Findings from the field of Developmental Origins of Health and Disease (DOHaD) suggest that some of the most pressing public health problems facing communities today may begin much earlier than previously understood. In particular, this body of work provides evidence that social, physical, chemical, environmental, and behavioral influences in early life play a significant role in establishing vulnerabilities for chronic disease later in life. Further, because this work points to the importance of adverse environmental exposures that cluster in population groups, it suggests that existing opportunities to intervene at a population level may need to refocus their efforts “upstream” to …

A Livelihood Intervention To Improve Economic And Psychosocial Well-Being In Rural Uganda: Longitudinal Pilot Study, Bernard Kakuhikire, Diego Suquillo, Elly Atuhumuza, Rumbidzai Mushavi, Jessica M. Perkins, Atheendar S. Venkataramani, Sheri D. Weiser, David Bangsberg, Alexander C. Tsai

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV and poverty are inextricably intertwined in sub-Saharan Africa. Economic and livelihood intervention strategies have been suggested to help mitigate the adverse economic effects of HIV, but few intervention studies have focused specifically on HIV positive persons. We conducted three pilot studies to assess a livelihood intervention consisting of an initial orientation and loan package of chickens and associated implements to create poultry microenterprises. We enrolled 15 HIV-positive and 22 HIV-negative participants and followed them for up to 18 months. Over the course of follow-up, participants achieved high chicken survival and loan repayment rates. Median monthly income increased, and severe …

Gauci, Elli Leontsini, Robert H. Gilman

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible.

Methods: We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T. solium infection in a region of highly endemic disease in Peru. In phase 1, we assessed the effectiveness and feasibility of six intervention …

Food-Related Practices And Beliefs Of Rural Us Elementary And Middle School Teachers, Nancy Findholt, Betty T. Izumi, Jackilen Shannon, Thuan Nguyen

Community Health Faculty Publications and Presentations

INTRODUCTION:

Childhood obesity disproportionately affects rural populations; therefore, promoting healthy eating among rural children is essential. Teachers are important role models for children and can influence children's eating behaviors through their own behaviors and beliefs about food. This study examined the food-related practices and beliefs of rural elementary and middle school teachers.

METHODS:

Data were used from the SNACZ study, a school- and community-based trial conducted in rural Oregon. Kindergarten through eighth-grade teachers (n=87), teaching students usually aged 5-14 years, from eight rural school districts completed a baseline survey in November 2012 concerning their classroom food practices, eating behaviors at …

Wolf, J. Z. Metcalfe, P. Isaakidis, J. L. Davis, J. R. Zelnick, J.C.M. Brust, N. Naidu, M. Garretson, David Bangsberg, N. Padayatchi, G. Friedland

OHSU-PSU School of Public Health Faculty Publications and Presentations

BACKGROUND—Despite renewed focus on molecular tuberculosis (TB) diagnostics and new antimycobacterial agents, treatment outcomes for patients co-infected with drug-resistant TB and human immunodeficiency virus (HIV) remain dismal, in part due to lack of focus on medication adherence as part of a patient-centered continuum of care.

OBJECTIVE—To review current barriers to drug-resistant TB-HIV treatment and propose an alternative model to conventional approaches to treatment support.

DISCUSSION—Current national TB control programs rely heavily on directly observed therapy (DOT) as the centerpiece of treatment delivery and adherence support. Medication adherence and care for drug-resistant TB-HIV could be improved by fully implementing team-based patient-centered …

Racial And Ethnic Disparities In Desire For Reversal Of Sterilization Among U.S. Women, Ginny Garcia-Alexander, Kelly Gonzales, Elizabeth Carol Hauck

Sociology Faculty Publications and Presentations

Purpose: Female sterilization rates and subsequent desire for reversal of the procedure are substantially higher in minorities, low-income women, and those who use public insurance. Despite the disproportionate distribution of these outcomes, few studies in this area have considered the extent to which such disparities are attributable to a restricted set of contraceptive options among medically underserved populations, which may in turn explain higher rates of desire for reversal. Methods: We use the most recent wave of NSFG data (2011-2013) to estimate odds ratios for race/ethnicity on the likelihood of desire for reversal of sterilization, while controlling for an array …
