Inference On Overlapping Coefficients In Two Exponential Populations, Mohammad F. Al-Saleh, Hani M. Samawi

Biostatistics Faculty Publications

Three measures of overlap, namely Matusita’s measureρ , Morisita’s measure λ and Weitzman’s measure Δ are investigated in this article for two exponential populations with different means. It is well that the estimators of those measures of overlap are biased. The bias is of these estimators depends on the unknown overlap parameters. There are no closed-form, exact formulas, for those estimators variances or their exact sampling distributions. Monte Carlo evaluations are used to study the bias and precision of the proposed overlap measures. Bootstrap method and Taylor series approximation are used to construct confidence intervals for the overlap measures.

Infant Mortality Trends Among Georgia Residents, 1995-2003: Targeting Healthy People’S 2010 Goals, Diana Sturges, Laura Gunn, Padmini Shankar, Shrikrishna Shroff

Journal of the Georgia Public Health Association

Population-based trends in infant mortality among Georgia Residents between 1995 and 2003 were assessed on characteristics such as race, birth weight, neonatal and post-neonatal periods, and cause of death. A statistical analysis was conducted to show that the Georgia infant mortality rate (IMR) remained constant throughout the study period and averaged 8.67 per 1,000 live births. The analysis revealed racial disparities, with an IMR ranging from 6.03 in white infants to 13.76 in black infants, with less than one percent (0.86%) change, on average, among the differences between black and white mortality rates across the nine-year period. The disparities were …

Risk Factors For Hiv Transmission Among Hispanic Men Who Have Sex With Men In Atlanta, Valerie A. Hepburn, Denyse N. Nanan

Journal of the Georgia Public Health Association

This study assessed and compared demographic factors, psychosocial factors, health seeking behavior, and sexual practices of two convenience samples of Hispanic/Latino gay men and men who have sex with men (MSM) in the metropolitan Atlanta region. The aim was to obtain data on emerging HIV/AIDS patterns in this group. Bilingual surveys were conducted in 2000 and 2006 at local gay bars. Discrepancies observed between HIV/AIDS knowledge and sexual behaviors in 2000 were replicated in 2006. Contrary to expected improvements due to enhanced HIV/AIDS education and awareness, risk behavior for HIV/STDs increased significantly between 2000 and 2006. These findings should inform …

Health Literacy Levels Among Adult Support Group Members And The General Adult Public : A Focus Group Approach, Daniel R. Czech, June Alberto, A. Barry Joyner

Journal of the Georgia Public Health Association

Health literacy has been identified as lacking in 47% of Americans (The National Academies, 2004). While health literacy reports of studies conducted in the southern section of the United States are available (DeWalt et al., 2004; Kennen et al. 2005), this research team found limited research that provides health literacy levels of the southeast, rural Georgia population. The purpose of this exploratory study was to examine and compare health literacy of health-related support group members and non group members in southeast Georgia utilizing a focus group methodology developed by Kreuger (1994). After Institutional Review Board approval at a local university, …

Alien Crustacean Decapods From The Aegean Coast Of Turkey, M. Baki Yokes, S. Ünsal Karhan, Erdogan Okus, Ahsen Yüksek, Asli Aslan, I. Noyan Yilmaz, Nazli Demirel, Volkan Demir, Bella S. Galil

Asli Aslan

Thirty of the 33 alien decapod crustacean species that have been reported off the Turkish Mediterranean coast are believed to have invaded the region via the Suez Canal, but only three of the species have been recorded along the Turkish Aegean coast. The marine biota of Gökova Bay, Datça Peninsula and Gulf of Fethiye, on the southern Aegean coast of Turkey, was studied by diving between 2002 and 2006. Of the eight Erythrean alien decapod species collected there, five constitute new records for the Aegean Sea and three are newly recorded from the Turkish coast of the Aegean Sea.

Yelena N. Tarasenko

Objective: The purpose of this research was to examine the content of physicians’ colorectal cancer screening recommendations. More specifically, using the framework of informed decision making synthesized by Braddock and colleagues, we conducted a qualitative study of the content of recommendations to describe how physicians are currently presenting this information to patients.

Methods: We conducted semi-structured interviews with 65 primary care physicians. We analyzed responses to a question designed to elicit how the physicians typically communicate their recommendation.

Results: Almost all of the physicians (98.5%) addressed the “nature of decision” element. A majority of physicians discussed “uncertainties …

Clinicians’ Perception Of Inmates’ Satisfaction With Mental Health Services, Jerry B. Daniel, Wynne S. Korr

Journal of the Georgia Public Health Association

A growing body of literature addresses the mental health needs of prison inmates; however, very little research has examined mental health services among this population. Based on the Behavioral Model of Health Services Use (Andersen Model), the current study examined clinicians’ perception of inmates’ satisfaction with mental health services. The study’s main objective was to identify the effect of three major groups of predictor variables (predisposing, enabling, and need) on clinicians’ perception with inmates’ satisfaction with mental health services. The study utilized an exploratory, survey methodology. Although only a few variables were found to be statistically significant in the multivariate …

Modifying And Validating A Quality Of Life Measure To Fit Your Patient Population, Michelle R. Johnson, J Ross Maclean, Rebecca L. Rogers, Donna M. Fick, Andre Kallab

Journal of the Georgia Public Health Association

Introduction: A well-developed quality of life (QoL) instrument is valuable in identifying the burden of illness. We were interested in exploring whether existing QoL instruments were suitable for patients in our medical setting and, if not, whether this could be rectified by adapting an existing valid and reliable instrument to meet the specific needs of our patient population. For the purposes of this study, we chose to evaluate the quality of life of patients with breast cancer. Specifically, we were interested in two aspects of QoL in women with breast cancer. The first was whether existing instruments were pertinent to …

Multi-Level Evaluation Of A Perinatal Health Program In Rural Southeast Georgia, Swati Raychowdhury, Stuart H. Tedders, Greta O'Steen, Sarah Jones

Journal of the Georgia Public Health Association

Problem: Infant mortality has declined steadily in the past decade, however, significant disparities associate with lack of adequate perinatal health services and barriers to access disproportionately impact women residing in rural areas. In Georgia, data suggest significant challenges with respect to birth outcomes, and this problem seems to be exacerbated in rural regions of state. The objective of this presentation is to report on the impact of a regional perinatal health care collaborative implemented in rural southeast Georgia.

Method: Analysis of pre-intervention and post-intervention birth outcomes (gestational age, birth weight and infant mortality) served as the focal point programmatic evaluation. …

The Breast And Cervical Cancer Prevention And Treatment Act (Bccpta) In Georgia: Women Covered And Medicaid Costs In 2003, E. Kathleen Adams, Sarah C. Blake, Cheryl Raskind-Hood, Linien Chien, Mei Zhou, Jonathan Liff, William Eley

Journal of the Georgia Public Health Association

The Breast and Cervical Cancer Prevention and Treatment Act (BCCPTA) provided states with an optional Medicaid eligibility category for uninsured women with breast and/or cervical cancers. The BCCPTA is the first and only such effort to use a population-based public health screening program, the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to provide a pathway to publicly funded health insurance for otherwise uninsured low-income women. Georgia was one of the first states to adopt the BCCPTA and was one of only twelve states that provided Medicaid eligibility to women screened by non-NBCCEDP providers. We use 2003 Georgia Medicaid …

Relationship Of Fruit And Vegetable Servings And Self-Reported Diabetics In The Southeast And Northeast, Marylen Rimando, Faye Lopez, Haritha Battula

Journal of the Georgia Public Health Association

According to the American Diabetes Association, most diabetic patients are not consuming the recommended 3-5 servings of vegetables and 2-4 servings of fruits a day. This study examined fruit and vegetable servings of self-reported diabetics (N=35,407) in select southeastern and northeastern states using Behavioral Risk Factor Surveillance System (BRFSS) 2005 data. The estimate for both fruit and vegetable servings and self-reported diabetes was determined using multivariate logistic regression, adjusting for sociodemographics and geographic region. The results indicated a significant difference between fruit and vegetable servings for diabetics and non-diabetics (p<0.0001). A higher percentage of diabetics in the northeast consumed more than three servings of fruit and vegetables when compared to diabetics in the southeast. Respondents in the northeast were 21% more likely to consume five or more servings of fruit and vegetables and 16% less likely to be diabetic than those in the southeast after adjusting for age, race, sex, and geographic region. In conclusion, diabetics in the northeast consumed more servings of fruit and vegetables than did those in the southeast. Multiple factors influence fruit and vegetable consumption and diabetes and should be considered when developing targeted nutritional interventions. Diabetes educators, nurses, and physicians can encourage diabetic patients to consume more fruit and vegetables and motivate them to continue eating fruit and vegetables.

Individual Differences In Well-Being In Older Breast Cancer Survivors, Elizabeth A. Perkins, Brent J. Small, Lodovico Balducci, Martine Extermann, Claire Robb, William E. Haley

Epidemiology Faculty Publications

Older women who survive breast cancer may differ significantly in their long-term well-being. Using a risk and protective factors model, we studied predictors of well-being in 127 women age 70 and above with a history of at least one year's survival of breast cancer. Mean post-cancer survivorship was 5.1 years. Using life satisfaction, depression and general health perceptions as outcome variables, we assessed whether demographic variables, cancer-related variables, health status and psychosocial resources predicted variability in well-being using correlational and hierarchical regression analyses. Higher age predicted increased depression but was not associated with life satisfaction or general health perceptions. Cancer-related …
