Racial/Ethnic Disparities In Survival Among Men Diagnosed With Prostate Cancer In Texas, Arica L. White, Ann L. Coker, Xianglin L. Du, Katherine S. Eggleston, Melanie Williams

CRVAW Faculty Journal Articles

BACKGROUND:

To the authors' knowledge, few studies to date have examined racial differences in prostate cancer survival while controlling for socioeconomic status (SES). No such studies have examined this association in Texas, a large state with significant ethnic and racial diversity. The objective of this analysis was to determine whether racial disparities in survival for men diagnosed with prostate cancer in Texas from 1995 through 2002 remained after adjusting for SES, rural residence, and stage of disease.

METHODS:

A cohort of 87,449 men who were diagnosed with prostate cancer was identified from the Texas Cancer Registry. The SES measure was …

Kriged And Modeled Ambient Air Levels Of Benzene In An Urban Environment: An Exposure Assessment Study, Kristina W. Whitworth, Elaine Symanski, Dejian Lai, Ann L. Coker

CRVAW Faculty Journal Articles

Background. There is increasing concern regarding the potential adverse health effects of air pollution, particularly hazardous air pollutants (HAPs). However, quantifying exposure to these pollutants is problematic. Objective. Our goal was to explore the utility of kriging, a spatial interpolation method, for exposure assessment in epidemiologic studies of HAPs. We used benzene as an example and compared census tract-level kriged predictions to estimates obtained from the 1999 U.S. EPA National Air Toxics Assessment (NATA), Assessment System for Population Exposure Nationwide (ASPEN) model. Methods. Kriged predictions were generated for 649 census tracts in Harris County, Texas using estimates of annual benzene …

Objective: We investigated whether Latina mothers who were and were not human papillomavirus (HPV) positive differed in their knowledge and acceptance of the HPV vaccine for their children.

Methods: We conducted a cross–sectional survey among women aged 18–64 years between April 2007 and April 2008. Data collectors conducted in-person interviews in community clinics with 215 HPV-negative women and 190 HPV-positive women (with respective response rates of 64% and 84%). Most (83%) HPV-positive women were recruited at dysplasia clinics. Although no HPV-negative women were recruited at dysplasia clinics, they were recruited at other low-income public and private clinics.

Results: After adjustment …

Violence Against Women Raises Risk Of Cervical Cancer, Ann L. Coker, Claudia Hopenhayn, Christopher P. Desimone, Heather M. Bush, Leslie Crofford

CRVAW Faculty Journal Articles

Background: An emerging literature suggests that violence against women (VAW), particularly sexual violence, may increase the risk of acquiring a sexually transmitted infection (STI) and, therefore, may be associated with cervical cancer development. The purpose of this cross-sectional analysis was to determine if women who had experienced violence had higher prevalence rates of invasive cervical cancer.

Methods: Women aged 18–88 who joined the Kentucky Women’s Health Registry (2006–2007) and completed a questionnaire were included in the sample. Multivariate logistic regression analyses were used to adjust odds ratio (OR) for confounders (e.g., age, education, current marital status, lifetime illegal drug use, …

Social Factors Affecting Treatment Of Cervical Cancer: Ethical Issues And Policy Implications, Shannon N. Westin, Dan Bustillos, Jacalyn B. Gano, Margaret M. Fields, Ann L. Coker, Charlotte C. Sun, Lois M. Ramondetta

CRVAW Faculty Journal Articles

Health care in the United States has become a privilege rather than a right. Patients who have the greatest need are the ones most likely to be denied this privilege. Despite recent advances in disease detection and treatment, many patients do not receive even the bare minimum of care. The high complexity of the health care system in the setting of patients with low levels of health literacy significantly affects the ability to seek and receive treatment in a timely fashion. In addition, lack of insurance, transportation, and social support further complicate access to care. To truly provide a standard …

Psychosocial Stress And Prostate Cancer: A Theoretical Model, Gary L. Ellison, Ann L. Coker, James R. Hebert, Maureen Sanderson, Charmaine D. Royal, Sally P. Weinrich

CRVAW Faculty Journal Articles

African-American men are more likely to develop and die from prostate cancer than are European-American men; yet, factors responsible for the racial disparity in incidence and mortality have not been elucidated. Socioeconomic disadvantage can lead to psychosocial stress and may be linked to negative lifestyle behaviors. Regardless of socioeconomic position, African-American men routinely experience racism-induced stress. We propose a theoretical framework for an association between psychosocial stress and prostate cancer. With the context of history and culture, we further propose that psychosocial stress may partially explain the variable incidence of prostate cancer between these diverse groups. Psychosocial stress may negatively …

CRVAW Faculty Journal Articles

Intimate partner violence (IPV) is associated with a range of adverse physical health outcomes, including chronic and infectious diseases. An emerging literature suggests that partner violence and specifically sexual violence may be associated with an increased risk of cervical neoplasia. To assess the risk of preinvasive and invasive cervical cancer in a cross-sectional study of women screened for IPV by type, frequency and duration, 1152 women ages 18–65 were recruited from family practice clinics in 1997–1998. They were screened for IPV during a brief in-clinic interview, and health history and current status were assessed in a follow-up interview. Of 1152 …

Street-Based Female Adolescent Puerto Rican Sex Workers: Contextual Issues And Health Needs, Margarita Burgos, Donna L. Richter, Belinda Reininger, Ann L. Coker, Ruth Saunders, Margarita Alegria, Mildred Vera

CRVAW Faculty Journal Articles

Adolescent sex workers potentially have many health needs but are included rarely in health assessments; therefore, little is known about their needs or how to reach them. This study examines the motivations, social context, and health needs of street-based adolescent sex workers. The results show these youths are more likely to experience negative health outcomes, such as unintended pregnancies and sexually transmitted infections, when they are using drugs or are depressed. These findings suggest the need for comprehensive programming to include individual, interpersonal, and greater environmental interventions. Examples for reaching adolescent sex workers are discussed.

Physical Violence During Pregnancy: Maternal Complications And Birth Outcomes, Vilma E. Cokkinides, Ann L. Coker, Maureen Sanderson, Cheryl Addy, Lesa Bethea

CRVAW Faculty Journal Articles

CRVAW Faculty Journal Articles

Violence during pregnancy directly impacts the mental and physical health of pregnant women. We assessed the prevalence and correlates of physical violence around the time of pregnancy in a representative sample of 6,718 women in South Carolina. Physical violence, defined as "being physically hurt by husband or partner" or "being involved in a physical fight" was reported by 10.9% of recently pregnant women. These were correlates of violence: experiencing increased numbers of stressful life events, being unmarried, having increased parity, being on Medicaid, and having an unwanted pregnancy. Screening to identify violence in pregnancy in health care settings is vital …

Violence Against Women In Sierra Leone: Frequency And Correlates Of Intimate Partner Violence And Forced Sexual Intercourse, Ann L. Coker, Donna L. Richter

CRVAW Faculty Journal Articles

Violence against women is a significant public health problem which impacts women, men, and children. Little is known about the frequency or correlates of violence against women in Africa. In this cross-sectional study, we found that 66.7% of 144 women surveyed in a study of AIDS knowledge, attitude, and behaviours, report being beaten by an intimate male partner and 50.7% report having ever been forced to have sexual intercourse; 76.6% of women report either forced sex or intimate partner violence. Circumcised women were most likely to report intimate partner violence and forced sexual intercourse. To improve the health of women …
