Mcglashan, Robert L. Stout, Donna S. Bender, Andrew E. Skodol, Charles A. Sanislow, Leslie C. Morey, John G. Gunderson

Charles A. Sanislow, Ph.D.

This cross-sectional study examined the associations between neighborhood-level socioeconomic-status (NSES), and psychosocial functioning and personality pathology among 335 adults drawn from the Collaborative Longitudinal Personality Disorders Study. Participants belonged to four personality disorder (PD) diagnostic groups: Avoidant, Borderline, Schizotypal, and Obsessive Compulsive. Global functioning, social adjustment, and PD symptoms were assessed following a minimum two-year period of residential stability. Residence in higher-risk neighborhoods was associated with more PD symptoms and lower levels of functioning and social adjustment. These relationships were consistent after controlling for individual-level socioeconomic-status and ethnicity; however, the positive association between neighborhood-level socio-economic risk and PD symptoms was …


Risk Of Kidney Stones In Living Kidney Donors: A Matched Cohort Study, Sonia Thomas Dec 2013

Risk Of Kidney Stones In Living Kidney Donors: A Matched Cohort Study, Sonia Thomas

Electronic Thesis and Dissertation Repository

A kidney stone in a person with one kidney requires urgent attention which may result in surgical and/or hospital attention. We conducted a matched retrospective cohort study to determine if living kidney donors compared to healthy non-donors have a higher risk of: 1) kidney stones with surgical intervention, and 2) hospital encounters for kidney stones. We reviewed and linked information from pre-donation charts to Ontario healthcare databases. We selected healthy non-donors from the general population, matching ten non-donors to every donor, to generate a cohort of 2,019 donors and 20,190 non-donors. There was no difference in the rate of 1) …


Who Done It? Rurality Vs. Ses As Critical Factors In Evaluating The Prevalence Of Child Psychosocial Concerns In Primary Care, Robert M. Tolliver Dec 2013

Who Done It? Rurality Vs. Ses As Critical Factors In Evaluating The Prevalence Of Child Psychosocial Concerns In Primary Care, Robert M. Tolliver

Electronic Theses and Dissertations

The purpose of this study was to evaluate the prevalence of child psychosocial concerns in rural primary care, hypothesized to be greater than national averages due to lacking mental health services in rural areas. This study was an examination of the role of SES, various definitions of “rural,” and the interaction of SES and rurality, in predicting parent-reported child psychosocial concerns in Appalachian primary care clinics. Caregivers presenting with their child at one of 8 pediatric primary care sites (n=2,672) were recruited to complete a measure assessing demographics and the Pediatric Symptom Checklist (PSC). Results showed that while rural status …

Local Tobacco Control: Application Of The Essential Public Health Services Model In A County Health Department’S Efforts To Put It Out Rockland, Lisa D. Lieberman, Una Diffley, Sandy King, Shelley Chanler, Maryanne Ferrera, Oscar Alleyne, Joan Facelle

Department of Public Health Scholarship and Creative Works

In 2000, Rockland County, a small suburban county north of New York City, dedicated $1 million of its Master Settlement Agreement funds to a comprehensive tobacco control program, Put It Out Rockland. Developed and implemented by the county health department, this program used an essential public health services model and an ongoing financial investment, within the context of strong statewide tobacco control efforts, to lower adult smoking rates to 9.7% and to reduce both smoking among youths and exposure to secondhand smoke over the ensuing decade. By combining state funds and local dollars for a total of $6.75 cost per …

Short- And Long-Term Associations Between Widowhood And Mortality In The United States: Longitudinal Analyses, J. Robin Moon, M. Maria Glamour, Anusha M. Vable, Sze Yan Liu, S.V. Subramanian

Department of Public Health Scholarship and Creative Works

Background

Past research shows that spousal death results in elevated mortality risk for the surviving spouse. However, most prior studies have inadequately controlled for socioeconomic status (SES), and it is unclear whether this ‘widowhood effect’ persists over time.

Methods

Health and Retirement Study participants aged 50+ years and married in 1998 (n = 12 316) were followed through 2008 for widowhood status and mortality (2912 deaths). Discrete-time survival analysis was used to compare mortality for the widowed versus the married.

Results

Odds of mortality during the first 3 months post-widowhood were significantly higher than in the continuously married (odds ratio …


Structural Approaches To Health Promotion: What Do We Need To Know About Policy And Environmental Change?, Lisa D. Lieberman, Shelley D. Golden, Jo Anne L. Earp Oct 2013

Structural Approaches To Health Promotion: What Do We Need To Know About Policy And Environmental Change?, Lisa D. Lieberman, Shelley D. Golden, Jo Anne L. Earp

Department of Public Health Scholarship and Creative Works

Although the public health literature has increasingly called on practitioners to implement changes to social, environmental, and political structures as a means of improving population health, recent research suggests that articles evaluating organization, community, or policy changes are more limited than those focused on programs with individuals or their social networks. Even when these approaches appear promising, we do not fully understand whether they will benefit all population groups or can be successful in the absence of accompanying individually oriented programs. The role of this broad category of approaches, including both policy and environmental changes, in decreasing health disparities is …

Net Reclassification Index: A Misleading Measure Of Prediction Improvement, Margaret Sullivan Pepe, Holly Janes, Kathleen F. Kerr, Bruce M. Psaty Sep 2013

Net Reclassification Index: A Misleading Measure Of Prediction Improvement, Margaret Sullivan Pepe, Holly Janes, Kathleen F. Kerr, Bruce M. Psaty

UW Biostatistics Working Paper Series

The evaluation of biomarkers to improve risk prediction is a common theme in modern research. Since its introduction in 2008, the net reclassification index (NRI) (Pencina et al. 2008, Pencina et al. 2011) has gained widespread use as a measure of prediction performance with over 1,200 citations as of June 30, 2013. The NRI is considered by some to be more sensitive to clinically important changes in risk than the traditional change in the AUC (Delta AUC) statistic (Hlatky et al. 2009). Recent statistical research has raised questions, however, about the validity of conclusions based on the NRI. (Hilden and …


Net Reclassification Indices For Evaluating Risk Prediction Instruments: A Critical Review, Kathleen F. Kerr, Zheyu Wang, Holly Janes, Robyn Mcclelland, Bruce M. Psaty, Margaret S. Pepe Aug 2013

Net Reclassification Indices For Evaluating Risk Prediction Instruments: A Critical Review, Kathleen F. Kerr, Zheyu Wang, Holly Janes, Robyn Mcclelland, Bruce M. Psaty, Margaret S. Pepe

UW Biostatistics Working Paper Series

Background Net Reclassification Indices (NRI) have recently become popular statistics for measuring the prediction increment of new biomarkers.

Methods In this review, we examine the various types of NRI statistics and their correct interpretations. We evaluate the advantages and disadvantages of the NRI approach. For pre-defined risk categories, we relate NRI to existing measures of the prediction increment. We also consider statistical methodology for constructing confidence intervals for NRI statistics and evaluate the merits of NRI-based hypothesis testing.

Conclusions Investigators using NRI statistics should report them separately for events (cases) and nonevents (controls). When there are two risk categories, the …


Atypical Antipsychotic Drugs And The Risk Of Acute Kidney Injury: A Population-Based Cohort Study, Yoseob Joseph Hwang Jul 2013

Atypical Antipsychotic Drugs And The Risk Of Acute Kidney Injury: A Population-Based Cohort Study, Yoseob Joseph Hwang

Electronic Thesis and Dissertation Repository

Older adults are frequently prescribed atypical antipsychotic drugs and may be at a risk for kidney-related adverse events. This population-based retrospective cohort study examined the 90-day risk of acute kidney injury (AKI) and the potential reasons for AKI in 96,471 matched pairs of older adults who received and who did not receive a new atypical antipsychotic drug prescription from 2003 to 2011 in Ontario. Atypical antipsychotic drug use was associated with a higher risk of hospitalization with AKI (relative risk (RR) 2.06 [95% confidence interval (CI) 1.85–2.29]). The drug use was also associated with potential reasons for AKI including hypotension …


Patency And Complication Rates Of The Arteriovenous Fistula: A Systematic Review, Ahmed A. Al-Jaishi Jul 2013

Patency And Complication Rates Of The Arteriovenous Fistula: A Systematic Review, Ahmed A. Al-Jaishi

Electronic Thesis and Dissertation Repository

Advantages of fistulas, which include long patency and low complication rates, were ascertained over two decades ago and may not apply to the contemporary dialysis population. We conducted a systematic review to summarize the patency and complication rates of fistulas from literature published after 1999. We screened 7,008 citations and 62 articles met our criteria. The risk of primary failure was 27% (95% confidence interval (CI): 23–32%). When primary failures were included, the primary and secondary patency rates were 59% (CI 53–64%) and 66% (CI 58–74%) at one year, respectively. The median rates of infection, ischemic steal syndrome, and thrombosis …


Violence Among Young Adults Receiving Housing Assistance: Vouchers, Race, And Transitions Into Adulthood, Tamara Leech Jul 2013

Violence Among Young Adults Receiving Housing Assistance: Vouchers, Race, And Transitions Into Adulthood, Tamara Leech

Department of Public Health Scholarship and Creative Works

Scholarly literature has been very attentive to violence among adolescents whose families receive vouchers. Yet, it provides little information about violence among the more than 400,000 very young adults who head households that receive vouchers. This article explores this relationship, paying particular attention to life course considerations and racial context. Data on 18–22-year-olds, numbering 208, who received housing assistance and participated in the National Longitudinal Survey of Youth 1997 in 2002 indicate that normative theoretical models may not accurately capture the relationship between the transition to adulthood and violence within this group. Results also suggest that among those who experience …


Maribel Gamon - Multidrug-Resistant Tuberculosis In India: Solving A Problem By Reconstructing The Public Health Infrastructure, Maribel Gamon Jul 2013

Maribel Gamon - Multidrug-Resistant Tuberculosis In India: Solving A Problem By Reconstructing The Public Health Infrastructure, Maribel Gamon

Ronald E. McNair Scholars Program 2013

Mycobacterium tuberculosis, commonly referred to as TB, is responsible for causing about 630,000 cases per year of infectious diseases worldwide. Recently, multidrug resistant tuberculosis (MDR-TB) has become an alarming public health concern. In addition, many developing countries lack effective treatment programs. India is one of those countries with a high prevalence of TB, seemingly affected by disconnectedness in their public health infrastructure. India, although a developing country, is still burdened with both chronic and infectious diseases, and there is a reactive public health system that must place focus on long-term effects of emerging resistant strains of TB. It is important …

Jorge L. Yarzebski

BACKGROUND: Heart failure is a highly prevalent, morbid, and costly disease with a poor long-term prognosis. Evidence-based therapies utilized over the past 2 decades hold the promise of improved outcomes, yet few contemporary studies have examined survival trends in patients with acute heart failure. The primary objective of this population-based study was to describe trends in short- and long-term survival in patients hospitalized with acute decompensated heart failure (ADHF). A secondary objective was to examine patient characteristics associated with decreased long-term survival.

METHODS AND RESULTS: We reviewed the medical records of 9748 patients hospitalized with ADHF at all 11 medical …


Empowerment-Based Positive Youth Development: A New Understanding Of Healthy Development For African American Youth, Raphael Travis Jr., Tamara Leech Jun 2013

Empowerment-Based Positive Youth Development: A New Understanding Of Healthy Development For African American Youth, Raphael Travis Jr., Tamara Leech

Department of Public Health Scholarship and Creative Works

A shift occurred in research about adolescents in the general population. Research is moving away from deficits toward a resilience paradigm and understanding trajectories of positive youth development. This shift has been less consistent in research and practice with African American youth. A gap also exists in understanding whether individual youth development dimensions generate potential in other dimensions. This study presents an empowerment-based positive youth development model. It builds upon existing research to present a new vision of healthy development for African American youth that is strengths-based, developmental, culture-bound, and action-oriented. It emphasizes the relationship between person and environment, the …

Factors Associated With The Risk Of Adenoma Recurrence In Distal And Proximal Colon, Adeyinka Laiyemo, Chyke Doubeni, Paul Pinsky, V. Paul Doria-Rose, Pamela Marcus, Robert Schoen, Elaine Lanza, Amanda Cross

Chyke A. Doubeni

Background/Aims: Colonoscopy may be less effective in preventing cancer in the proximal colon. We evaluated whether risk factors for adenoma recurrence exhibit differential effect on adenoma recurrence by colon subsite.

Methods: We examined the association of age, sex, body mass index, smoking status and use of nonsteroidal anti-inflammatory drugs (NSAIDs) on proximal and distal adenoma recurrence among 1,864 participants in the Polyp Prevention Trial. We used multinomial logistic regression models to calculate the relative risk ratios (RRR) and 95% CI.

Results: 733 (39.3%) participants had adenoma recurrence (228 distal only, 369 proximal only and 136 synchronous proximal and distal adenoma). …

Chyke A. Doubeni

BACKGROUND: It is unclear whether the higher burden from colorectal cancer among blacks is due to an increased biological susceptibility. OBJECTIVE: To determine whether non-Hispanic blacks (blacks) have a higher risk of adenoma recurrence than non-Hispanic whites (whites) after removal of colorectal adenoma. DESIGN: Secondary analysis of the Polyp Prevention Trial (PPT) data. SETTING: United States. PATIENTS: Patients were 1668 self-identified whites and 153 blacks who completed the 4-year trial. Of these, 688 whites and 55 blacks enrolled in a posttrial, passive Polyp Prevention Trial Continued Follow-up Study (PPT-CFS) and underwent another colonoscopy. MAIN OUTCOME MEASUREMENTS: Recurrence and location of …


Associations Between Alcohol Consumption And Fasting Blood Glucose In Young Adults, Julie Ann Lucca Jun 2013

Associations Between Alcohol Consumption And Fasting Blood Glucose In Young Adults, Julie Ann Lucca

Master's Theses

Current research shows moderate alcohol consumption is associated with decreased risk of diabetes and excessive consumption or binge drinking can cause insulin resistance and diabetes. In 2010, diabetes was the seventh leading cause of death in the United Statesand was responsible for significant health complications: blindness, kidney failure, and limb amputations, and is a large national economic burden. Fasting blood glucose (FBG) is a tool used to help diagnose diabetes. Abnormally high FBG, ≥100 mg/dl, is indicative of diabetes and pre-diabetes. Few studies have observed diabetic prevalence among young adults or college students. Studying young adults can help provide added …

Publications from Provost Junius J. Gonzales

BACKGROUND

Depression is prevalent in primary care (PC) practices and poses a considerable public health burden in the United States. Despite nearly four decades of efforts to improve depression care quality in PC practices, a gap remains between desired treatment outcomes and the reality of how depression care is delivered.

OBJECTIVE

This article presents a real-world PC practice model of depression care, elucidating the processes and their influencing conditions.

DESIGN

Grounded theory methodology was used for the data collection and analysis to develop a depression care model. Data were collected from 70 individual interviews (60 to 70 min each), three …

Type Of High-School Credentials And Older Age Adl And Iadl Limitations: Is The Ged Credential Equivalent To A Diploma?, Sze Yan Liu, Niraj R. Chavan, M. Maria Glymour

Department of Public Health Scholarship and Creative Works

Purpose: Educational attainment is a robust predictor of disability in elderly Americans: older adults with high-school (HS) diplomas have a substantially lower disability than individuals who did not complete HS. General Educational Development (GED) diplomas now comprise almost 20% of new HS credentials issued annually in the United States but it is unknown whether the apparent health advantages of HS diplomas extend to GED credentials. This study examines whether adults older than 50 years with GEDs have higher odds of incident instrumental or basic activities of daily living (IADLs) limitations compared with HS degree holders. Methods: We compared odds of …

Sybil L. Crawford

Purpose: Spirituality has been associated with better cardiac autonomic balance, but its association with cardiovascular risk is not well studied. We examined whether more frequent private spiritual activity was associated with reduced cardiovascular risk in postmenopausal women enrolled in the Women’s Health Initiative Observational Study. Methods: Frequency of private spiritual activity (prayer, Bible reading, and meditation) was selfreported at year 5 of follow-up. Cardiovascular outcomes were centrally adjudicated, and cardiovascular risk was estimated from proportional hazards models. Results: Final models included 43,708 women (mean age: 68.9±7.3; median follow-up: 7.0 years) free of cardiac disease through year 5 of follow-up. In …


The Net Reclassification Index (Nri): A Misleading Measure Of Prediction Improvement With Miscalibrated Or Overfit Models, Margaret Pepe, Jin Fang, Ziding Feng, Thomas Gerds, Jorgen Hilden Mar 2013

The Net Reclassification Index (Nri): A Misleading Measure Of Prediction Improvement With Miscalibrated Or Overfit Models, Margaret Pepe, Jin Fang, Ziding Feng, Thomas Gerds, Jorgen Hilden

UW Biostatistics Working Paper Series

The Net Reclassification Index (NRI) is a very popular measure for evaluating the improvement in prediction performance gained by adding a marker to a set of baseline predictors. However, the statistical properties of this novel measure have not been explored in depth. We demonstrate the alarming result that the NRI statistic calculated on a large test dataset using risk models derived from a training set is likely to be positive even when the new marker has no predictive information. A related theoretical example is provided in which a miscalibrated risk model that includes an uninformative marker is proven to erroneously …


Area Specific Self-Esteem, Values, And Adolescent Sexual Behavior, Michael Young, Joseph Donnelly, George Denny Feb 2013

Area Specific Self-Esteem, Values, And Adolescent Sexual Behavior, Michael Young, Joseph Donnelly, George Denny

Department of Public Health Scholarship and Creative Works

This study examined area-specific self-esteem scores by sexual behavior relative to adolescents' values concerning participation in sexual intercourse as an unmarried teenager. The sample consisted of 332 students in grades 7–12 from a Southern rural school district. Students were asked if they had ever had sexual intercourse (yes/no) and if they had participated in sexual intercourse in the last month (yes/no). Respondents also indicated on a 4-point scale their response to the statement “It is against my values to have sex as an unmarried teenager.” Data were analyzed using a 2 × 4 (behavior x values) analysis of variance for …


Comparing Two-Year Community College And Four-Year University Student Social And Behavioral Sexually Transmitted Infection Risk Factors, Oswald M. Attin Jan 2013

Comparing Two-Year Community College And Four-Year University Student Social And Behavioral Sexually Transmitted Infection Risk Factors, Oswald M. Attin

Faculty Dissertations

Sexually transmitted infections (STIs) could cause ectopic, cervical cancer, infertility, and organ damage to the heart, kidneys, and brain. This study compared several behavioral risk factors of STIs (condom use, number of sexual partners, type of sex (anal or vaginal) and drinking habits) between two distinct educational settings and their association with socioeconomic risk factors such as low income and parent’s lower level of education that are known to increase the incidence of STIs among college-aged students. This study was based on the precautionary-health-behavior model, where individuals act regardless of consequences, and the health-behavior-change model, where individual behaviors either increase …

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd Dec 2012

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd

Margaret S Pepe PhD

This chapter describes and critiques methods for evaluating the performance of markers to predict risk of a current or future clinical outcome. We consider three criteria that are important for evaluating a risk model: calibration, benefit for decision making and accurate classification. We also describe and discuss a variety of summary measures in common use for quantifying predictive information such as the area under the ROC curve and R-squared. The roles and problems with recently proposed risk reclassification approaches are discussed in detail.
