Associations Between Cadmium Exposure And Neurocognitive Test Scores In A Cross-Sectional Study Of Us Adults, Timothy Ciesielski, David C. Bellinger, Joel Schwartz, Russ Hauser, Robert O. Wright

Dartmouth Scholarship

Background: Low-level environmental cadmium exposure and neurotoxicity has not been well studied in adults. Our goal was to evaluate associations between neurocognitive exam scores and a biomarker of cumulative cadmium exposure among adults in the Third National Health and Nutrition Examination Survey (NHANES III).

Methods: NHANES III is a nationally representative cross-sectional survey of the U.S. population conducted between 1988 and 1994. We analyzed data from a subset of participants, age 20–59, who participated in a computer-based neurocognitive evaluation. There were four outcome measures: the Simple Reaction Time Test (SRTT: visual motor speed), the Symbol Digit Substitution Test (SDST: attention/perception), …

Development Of A Diagnostic Test Set To Assess Agreement In Breast Pathology: Practical Application Of The Guidelines For Reporting Reliability And Agreement Studies (Grras), Natalia V. Oster, Patricia A. Carney, Kimberly H. Allison, Donald L. Weaver, Lisa Reisch, Gary Longton, Tracy Onega

Dartmouth Scholarship

Diagnostic test sets are a valuable research tool that contributes importantly to the validity and reliability of studies that assess agreement in breast pathology. In order to fully understand the strengths and weaknesses of any agreement and reliability study, however, the methods should be fully reported. In this paper we provide a step-by-step description of the methods used to create four complex test sets for a study of diagnostic agreement among pathologists interpreting breast biopsy specimens. We use the newly developed Guidelines for Reporting Reliability and Agreement Studies (GRRAS) as a basis to report these methods.

Dissemination of prevention-focused evidence-based programs (EBPs) from research to community settings may improve population health and reduce health disparities, but such flow has been limited. Academic-community partnerships using community-based participatory research (CBPR) principles may support increased dissemination of EBPs to community-based organizations (CBOs). This qualitative study examined the EBP-related perceptions and needs of CBOs targeting underserved populations. As part of PLANET MassCONECT, a CBPR study, we conducted six key informant interviews with community leaders and four focus groups with CBO staff members in Boston, Worcester and Lawrence, Massachusetts, in 2008. Working definitions of EBPs among CBO staff members varied greatly …

Weight Stigma In Maternity Care: Women’S Experiences And Care Providers’ Attitudes, Kate Mulherin, Yvette D. Miller, Fiona Kate Barlow, Phillippa C. Diedrichs, Rachel Thompson

Dartmouth Scholarship

Weight stigma is pervasive in Western society and in healthcare settings, and has a negative impact on victims' psychological and physical health. In the context of an increasing focus on the management of overweight and obese women during and after pregnancy in research and clinical practice, the current studies aimed to examine the presence of weight stigma in maternity care. Addressing previous limitations in the weight stigma literature, this paper quantitatively explores the presence of weight stigma from both patient and care provider perspectives. Study One investigated associations between pre-pregnancy body mass index (BMI) and experiences of maternity care from …

Task-Based Noise Exposures For Farmers Involved In Grain Production, Michael J. Humann, Wayne T. Sanderson, Kelley J. Donham, Kevin M. Kelly

Epidemiology and Environmental Health Faculty Publications

Few studies have been done examining noise exposures associated with agricultural tasks. This study was conducted to address that research gap by calculating the noise exposures for tasks and equipment associated with grain production and assessing the variability in those exposures. An additional aim of this study was to identify tasks and equipment that could be targeted for intervention strategies as a means toward reducing the total noise exposures of farmers and farm workers. Through the use of personal noise dosimetry and direct observation, over 30,000 one-minute noise exposure measurements and corresponding task and equipment data were collected on 18 …

Cattle-Related Injuries And Farm Management Practices On Kentucky Beef Cattle Farms, Steven R. Browning, Susan C. Westneat, Wayne T. Sanderson, Deborah B. Reed

Epidemiology and Environmental Health Faculty Publications

While working on farms with livestock increases the risk of injury among farm workers in comparison to other commodity farms, few studies have examined the role offarm management practices in association with the risk of cattle-related injury. We examined the farm management practices of Kentucky beef cattle farms in association with self-reported rates of cattle-related injuries among workers. We conducted a mail survey of a random sample of 2,500 members of the Kentucky Cattlemen's Association. Results from 1,149 farm operators who were currently raising beef cattle and provided complete survey response are reported. During the busy season, the principal operator …

Journal Articles: Epidemiology

BACKGROUND: Since malaria is one of the foremost public health problems in Ethiopia, assessment of situation of the disease, and communities' knowledge and perceptions about malaria is necesary to institute appropriate preventive and control measures. Thus, the aim of this study was to assess malaria prevalence and knowledge, attitude and practice (KAP) about the disease among ShewaRobit Town community, northeastern Ethiopia.

METHODS: A community-based cross-sectional study was conducted in Shewa Robit Town from October to November 2011. A multi-stage random sampling technique was used to select the study participants. A total of 425 individuals were examined for malaria using thin …

Gaps In Survey Data On Cancer In American Indian And Alaska Native Populations: Examination Of Us Population Surveys, 1960-2010, Shinobu Watanabe-Galloway, Tinka Duran, Jim P. Stimpson, Corey Smith

Journal Articles: Epidemiology

INTRODUCTION: Population-based data are essential for quantifying the problems and measuring the progress made by comprehensive cancer control programs. However, cancer information specific to the American Indian/Alaska Native (AI/AN) population is not readily available. We identified major population-based surveys conducted in the United States that contain questions related to cancer, documented the AI/AN sample size in these surveys, and identified gaps in the types of cancer-related information these surveys collect.

METHODS: We conducted an Internet query of US Department of Health and Human Services agency websites and a Medline search to identify population-based surveys conducted in the United States from …

Determinants Of Negative Pathways To Care And Their Impact On Service Disengagement In First-Episode Psychosis., Kelly K. Anderson, Rebecca Fuhrer, Norbert Schmitz, Ashok K Malla

Epidemiology and Biostatistics Publications

PURPOSE: Although there have been numerous studies on pathways to care in first-episode psychosis (FEP), few have examined the determinants of the pathway to care and its impact on subsequent engagement with mental health services.

METHODS: Using a sample of 324 FEP patients from a catchment area-based early intervention (EI) program in Montréal, we estimated the association of several socio-demographic, clinical, and service-level factors with negative pathways to care and treatment delay. We also assessed the impact of the pathway to care on time to disengagement from EI services.

RESULTS: Few socio-demographic or clinical factors were predictive of negative pathways …

Tackling Overweight And Obesity: Does The Public Health Message Match The Science?, Katherine Hafekost, David Lawrence, Francis Mitrou, Therese O'Sullivan, Stephen Zubrick

Research outputs 2013

Background: Despite the increasing understanding of the mechanisms relating to weight loss and maintenance, there are currently no validated public health interventions that are able to achieve sustained long-term weight loss or to stem the increasing prevalence of obesity in the population. We aimed to examine the models of energy balance underpinning current research about weight-loss intervention from the field of public health, and to determine whether they are consistent with the model provided by basic science. EMBASE was searched for papers published in 2011 on weight-loss interventions. We extracted details of the population, nature of the intervention, and key …

Journal Articles: Epidemiology

The U.S. military represents a unique population within the human immunodeficiency virus 1 (HIV-1) pandemic. The last comprehensive study of HIV-1 in members of the U.S. Navy and Marine Corps (Sea Services) was completed in 2000, before large-scale combat operations were taking place. Here, we present molecular characterization of HIV-1 from 40 Sea Services personnel who were identified during their seroconversion window and initially classified as HIV-1 negative during screening. Protease/reverse transcriptase (pro/rt) and envelope (env) sequences were obtained from each member of the cohort. Phylogenetic analyses were carried out on these regions to determine relatedness within the cohort and …

Lead-Based Paint Awareness, Work Practices, And Compliance During Residential Construction And Renovation, James D. Blando, Nickita Antoine, Daniel Lefkowitz

Community & Environmental Health Faculty Publications

The U.S. Environmental Protection Agency recently implemented the Renovation, Repair and Painting (RRP) rule that applies to pre-1978 residences because of the potential presence of lead-based paint. Enforcement of this rule may be difficult and therefore it is crucial to understand the awareness and beliefs of contractors and the general public because these will likely be major determinants of exposures resulting from residential renovation work. The study described in this article utilized two mailed surveys: one directed to the general public and the other directed to contractors. The surveys were conducted in New Jersey and Virginia. Field observations were also …

Is The Reporting Timeliness Gap For Avian Flu And H1n1 Outbreaks In Global Health Surveillance Systems Associated With Country Transparency?, Feng-Jen Tsai, Eva Tseng, Chang-Chuan Chan, Hiko Tamashiro, Sandrine Motamed, André C Rougemont

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: This study aims to evaluate the length of time elapsed between reports of the same incidents related to avian flu and H1N1 outbreaks published by the WHO and ProMED-mail, the two major global health surveillance systems, before and after the amendment of the International Health Regulations in 2005 (IHR 2005) and to explore the association between country transparency and this timeliness gap.

METHODS: We recorded the initial release dates of each report related to avian flu or H1N1 listed on the WHO Disease Outbreak News site and the matching outbreak report from ProMED-mail, a non-governmental program for monitoring emerging …
