Social Policy

The Impact of the Oregon Health Plan on TANF Leavers Ability to Care for their Families' Health
• Karen Seccombe, Heather Hartley, Jason Newsom
• Funding from The Agency for Healthcare Research and Quality 9/1/01-8/31/04

This project will examine the effects of welfare reform on access to health insurance and use of health services among former welfare recipients and their children in Oregon. The study will determine how families leaving welfare for employment plan for and cope with the expiration of their one-year transitional Oregon Health Plan/Medicaid coverage, and what happens to them after losing their eligibility for the single year of transitional coverage. Preliminary research findings suggest that former welfare recipients are not necessarily gaining coverage from their employers, while at the same time they are losing their Medicaid benefits. The objective of the project is to contribute to sound public policy by providing an empirical basis for understanding the health needs of families transitioning off welfare.

Robert Wood Johnson Foundation Innovator Award
• Lawrence Wallack
• Funding by Robert Wood Johnson Foundation


In 2000, Dr. Wallack was selected by the Robert Wood Johnson Foundation as an Innovator Combating Substance Abuse. This was the inaugural year of what will be an annual award recognizing the outstanding contributions of five people to the field of substance abuse. Dr. Wallack received his award for his work relating to research regarding prevention, media advocacy, and social policy. The $300,000 award runs from January 2001 through December 2003. Dr. Wallack is using a portion of this research award to conduct a study of the Million Mom March, which is an organization attempting to mobilize grassroots efforts to develop sensible and responsible gun laws (see below).

Million Mom March: Building blocks of a New Movement for a New Century
• Lawrence Wallack, Liana Winett, and Linda Nettekoven
• Funding from Robert Wood Johnson Foundation

Researchers in this study conducted key informant interviews, analyzed procedural documentation, and reviewed national print news coverage of the May 2000 Million Mom March. The goal of this project was to gather the lessons learned in setting a gun policy agenda, making use of the Internet as an organizing tool, engaging the mass media, and promoting widespread mobilization of private citizens. The study further discusses the implications of the strategies used in the formation and advancement of the Million Mom March for the prevention of violence and promotion of sensible gun laws.

The California Wellness Foundation Violence Prevention Initiative: Policy and Public Education Program Evaluation
• Lawrence Wallack, Liana Winett, Karen Seccombe, Yvonne Michael
• Funding from California Wellness Foundation

This project evaluates the development and use of social capital among grantees (current and former) of The California Wellness Foundation Violence Prevention Initiative (VPI). Measures of social capital are used as indicators of enhanced capacity to effect social change and to document accomplishments of VPI grantees. The project will construct case studies of various VPI-sponsored policy efforts to prevent violence in California using a combination of media and document analysis, and semi-structured interviews with grantees, policy makers, and other key people from the violence prevention arena. In addition to evaluating the policy grantees, this project will develop an evaluation model to gauge a wide range of community and policy oriented projects.

Media Analysis


Frame Analysis of News About Juvenile Substance Abuse: A Project of the Northwest Communication Research Group
• Regina Lawrence
• Funding from Reclaiming Futures and the Robert Wood Johnson Foundation

This project analyzed national print media coverage of juvenile substance abuse in order to identify the ways that issue is commonly framed in the news. Key findiings include the fact that news coverage of juvenile substance abuse generally lacks depth and context and that the predominant angle on substance abuse in the news is prevention: How to keep "good" kids from going "bad". Intervention to help young people who have already developed a drug or alcohol problem is a less prominent topic, and delinquent youth with substance abuse problems are largely absent from newspaper coverage.

Starting a New Conversation: Environment, Health, and Interconnectedness, A Project of the Northwest Communication Research Group
• Lawrence Wallack, Regina Lawrence
• Funding from Nathan Cummings Foundation

This analysis for the Nathan Cummings Foundation explored the basis in news, public opinion, and academic research for expanding public discourse about the interconnectedness among human, animal, and environmental health. The study noted that substantive coverage of the interconnections between health and the environment were infrequently seen in news contexts. The study concluded that the issue of antibiotic resistance promised fertile ground for the efforts of the Nathan Cummings Foundation and other groups to enrich public discourse about human-animal-environment interconnectedness.

An Analysis of Recent News Coverage of Antibiotic Resistance, A Project of the Northwest Communication Research Group
• Regina Lawrence

This study offered a summary of news coverage of antibiotic resistance (ABR) in selected newspapers. The study concluded that ABR entered the news mainly through four kinds of news events: governmental activities; academic research; the release of new drugs; and the efforts of nongovernmental groups such as the Union of Concerned Scientists. While the problem of antibiotic overuse in livestock did receive some media attention, certain facts about the nature and scope of the problem were not clearly conveyed in the news, and news coverage focused more on the problem of antibiotics and livestock than on potential solutions.

Breast Cancer in the News/Media Advocacy in Cancer Prevention and Control, A Project of the Northwest Communication Research Group
• Lawrence Wallack, Liana Winett, Ralph Catalano

This three-year project assesses many aspects of cancer coverage in the news. The project is currently examining portrayals of breast and cervical cancer in five nationally recognized newspapers and on evening network television news. It has completed an analysis of data from a survey of journalists who report on breast and cervical cancer to determine decision making processes, selection of sources, audience response, and social utility of topic. The survey was conducted by the University of Missouri School of Journalism. The objective of this project is to assess the range and content of coverage of these diseases, as well as to provide information that will serve as the basis for improving the ways these cancers are covered in the future. Findings have implications for health reporters as well as those working to prevent, or provide services for people with breast and cervical cancer. Public health professionals, by understanding how news media cover health issues, can communicate more effectively with journalists and can respond to concerns the general public might have as a result of this coverage. A separate part of the research developed a model for assessing the impact of large scale campaigns to increase mammograms. Using time series analysis the study assessed rates of in-situ breast cancer in the months following a national breast cancer awareness campaign.

Reclaiming Futures: Building Community Solutions to Substance Abuse and Delinquency, A Project of the Northwest Communication Research Group
• Regina Lawrence, Liana Winett

This project provides an objective and comprehensive assessment of how substance abuse and treatment among juvenile offenders is covered in national print news. Research determined how prominently the problem of substance abuse and treatment among juveniles is covered in the news media and assessed prominence of news stories with measures of their length and placement. The study first analyzed whether the issue of juvenile offender substance abuse and treatment is primarily defined in the news as a criminal justice problem or a health problem. The study also analyzed the sources that journalists call on to explain and comment on the problem. Finally, the study examined how responsibility for addressing the problem is apportioned in the news.

Reading Between the Lines on Measure 7, A Project of the Northwest Communication Research Group
• Liana Winett, Regina Lawrence, Gerald Sussman

This project identified a range of arguments that were made for and against Oregon's Measure 7 in The Oregonian newspaper from August 2000 through February 2001. After identifying the breadth of arguments presented, the project folded them into categories according to the themes they emphasize, such as economic costs, quality of life, of the relationship between rights and public obligation. This project examines the underlying values that propel proponents' and opponents' arguments, the different methods the two sides employ in making their respective cases, and the types of appeals and information each side could provide in order to speak more directly to each other, and to the public.

Cancer Research


Determinants of the Spatial Distribution of Leukemia in Oregon
• Jan Semenza
• Funding by Medical Research Foundation of Oregon

This project aims to determine the spatio-temporal distribution of leukemia in Oregon and correlate the occurrence of leukemia to environmental exposures such as motor vehicle exhaust, tobacco smoke, and industrial emissions. Geographic Information System (GIS) will be used to map out leukemia cases along with other potential risk factors for leukemia such as demographic, occupational, and societal factors. This method is designed to reveal potential leukemia clusters in the state, but also highlight associations with specific risk factors that could have contributed to unusual clustering of leukemia cases. The Oregon State Cancer Registry (OSCaR) has collected cancer surveillance data since 1996 and this project will utilize these data for a novel and promising approach to cancer prevention and control in Oregon.

Estrogen and Breast Cancer Susceptibility
• Jan Semenza
• Funding by Oregon Cancer Center

This study aims to determine genetic susceptibility to breast cancer by analyzing genetic polymorphisms influencing estrogen metabolism, an important risk factor for breast cancer. Cumulative lifetime exposure to estrogen has been identified as a risk factor for breast cancer, and is known to play a role in the carcinogenic process. The means by which estrogen could increase the risk of breast cancer in some individuals but not in others remains to be determined. This research explores the possibility that genetic variability in genes coding for enzymes that metabolize estrogen alters the risk for breast cancer.

Genetic Susceptibility to Kidney Cancer
• Jan Semenza
• Funding by National Kidney Foundation and American Cancer Society, Oregon Chapter

This study attempts to elucidate the role that certain environmental exposures, such as smoking, medications, and dietary factors play in the development of kidney cancer. This research investigates the genetic underpinning of increased environmental susceptibility by assessing genetic alterations in genes that are involved in the metabolism of toxic substances. Kidney cancer patients and cancer-free subjects from the Portland Metropolitan Area will complete a detailed epidemiologic risk factor questionnaire.

The Oregon Health Survey
• Jan Semenza
• Funding by Northwest Health Foundation

This project aims to build an infrastructure in Oregon for establishing research on cancer prevention and etiology. Although cancer affects every segment of the population, certain individuals are more at risk than others. Individuals with certain environmental exposures such as smoking, UV irradiation, and dietary carcinogens are also at increased risk for cancer. It is likely that genetic risk factors modify the cancer risk in response to environmental factors. The project is designed to complement the recently initiated Oregon State Cancer Registry (OSCaR) and to enhance its usefulness by identifying and characterizing a complementary cancer-free control population.

Aging

Depression and Health Behavior in Late Life
• Mark Kaplan, Jason Newsom
• Funding by National Institute for Mental Health

The overall purpose of this study is to expand the health behavior-health status model to include depressive symptoms and related psychosocial factors as factors in the health of older adults. An understanding of these interactive and dynamic relationships between psychosocial resources, depression, and health behavior may lay the foundation for developing more effective public health interventions. The specific goals of this research are: (1 ) to assess the effects of depression and psychological distress on health behaiors among older adults, (2) to examine the role of depression and depressive symptoms (including their psychosocial antecedents) among older men and women who engage in behaviors which are harmful to their health, and (3) to initiate a longitudinal study to identify and assess the directionality of the causal relationships between general risk factors (including deficits in psychological and social resources and life event-related stress), depression, and health behaviors. The proposed study will utilize cross-sectional and panel data derived from the Canadian National Population Health Survey (NPHS).

Impact of Negative Social Exchanges in Later Life, A Project of the Institute on Aging
• Jason Newsom, Karen Rook
• Funding by National Institute on Aging

This project investigates the psychological and health consequences of positive social support and negative social interactions. Evidence has accumulated in recent years that indicates that older adult's negative exchanges with members of the social networks may be more consequential for well-being than their positive exchanges with network members. This project will interview 800 noninstitutionalized older adults every six months for 30 months. The study aims to compare the prevalence and impact of positive versus negative social exchanges, using an assessment strategy designed to produce comprehensive and maximally comparable measures of these two kinds of exchanges. The study will also investigate the role of social network characteristics, stressful life events, and personality characteristics as predictors of older adults' exposure and reactivity to negative social exchanges.

Longitudinal Study of Alcohol Use and Medical Care Utilization Among Older Adults, A Project of the Institute on Aging
• Jason Newsom, Mark Kaplan
• Funding by Alcoholic Beverage Medical Research Foundation

This longitudinal study will examine relationships between alcohol consumption and utilization of health care services. The study takes advantage of the Canadian National Population Health Survey involving some 17,626 individuals surveyed at baseline in 1994 and every other year thereafter. The study aims to examine the cross-sectional relationships between alcohol use and medical care utilization in the baseline survey; determine relationships between baseline alcohol use and subsequent medical care utilization in the longitudinal study; to describe changes in alcohol use patterns; to examine relationships between changes in alcohol consumption patterns and utilization of medical care over time; and compare result from the Canadian project with analogous information from the ongoing Health And Retirement Study in the United States. Results of this study will be of interest to health care managers and providers looking for ways to improve health status while minimizing utilization of scarce medical care resources.

Women and Youth

The Push for a "Female Viagra": An Analysis of the Role of the Pharmaceutical Industry
• Heather Hartley

This project examines the current medicalization of female sexual dysfunction (FSD). Largely defined and understood as a physiologically-based disease, researchers and pharmaceutical companies are more recently turning attention to developing medical treatments for FSD. Using a qualitative case study design, this study answers the question: Are evolving relationships between the pharmaceutical industry and researchers studying FSD promoting the medicalization of FSD? In so doing, the project assesses who is studying FSD, what they think they are studying (i.e., how they understand the phenomenon), what methods they are using, why they are studying it, and what sources of funding they have for the research.

Preventing Noise-induced Hearing Loss for School-age Youth
Judy Sobel

Dr. Sobel is working with Dr. Mary Meikle at the Oregon Hearing Research Center and the Department of Otolaryngology at OHSU on a large campaign to prevent noise-induced hearing loss in school age youth. Project components include, generating public awareness of the issue; targeting youth in school to alter risk-reducing behaviors; and developing resources for school teachers. Hearing loss prevention is an underrepresented content area in the health literature, and as such, there are many opportunities for
multidisciplinary scholarship.
