Center for Global Health Publications

[First paragraph] The 2001 World Trade Center and 2005 Hurricane disasters, and the 2014 Ebola outbreak were major events that tasked the United States’ public health emergency preparedness and response apparatus. The health and economic cost of these events is huge including over 4000 deaths and damages to infrastructure worth hundreds of billions of dollars. Unfortunately, the U.S. labor force was disproportionately affected (1–4). Similar public health impact of other disasters on workers has also been reported. In the immediate aftermath of the Gulf of Mexico oil spill, for instance, approximately 75% of those who developed acute health effects and …

Direct Measurement Of Bisphenol A (Bpa), Bpa Glucuronide And Bpa Sulfate In A Diverse And Low-Income Population Of Pregnant Women Reveals High Exposure, With Potential Implications For Previous Exposure Estimates: A Cross-Sectional Study., Roy R. Gerona, Janet Pan, Ami R. Zota, Jackie M. Schwartz, Matthew Friesen, Julia A. Taylor, Patricia A. Hunt, Tracey J. Woodruff

Environmental and Occupational Health Faculty Publications

BACKGROUND: Bisphenol A (BPA) is a ubiquitous, endocrine-disrupting environmental contaminant that increases risk of some adverse developmental effects. Thus, it is important to characterize BPA levels, metabolic fate and sources of exposure in pregnant women.

METHODS: We used an improved liquid chromatography-tandem mass spectrometry (LC-MS/MS) analytic method to directly and simultaneously measure unconjugated BPA (uBPA), BPA glucuronide and BPA sulfate in the urine of a population of ethnically and racially diverse, and predominately low-income pregnant women (n = 112) in their second trimester. We also administered a questionnaire on dietary and non-dietary sources of exposure to BPA.

An Analysis Of Water Collection Labor Among Women And Children In 24 Sub-Saharan African Countries., Jay Graham, Mitsuaki Hirai, Seung-Sup Kim

Environmental and Occupational Health Faculty Publications

BACKGROUND: It is estimated that more than two-thirds of the population in sub-Saharan Africa (SSA) must leave their home to collect water, putting them at risk for a variety of negative health outcomes. There is little research, however, quantifying who is most affected by long water collection times.

OBJECTIVES: This study aims to a) describe gender differences in water collection labor among both adults and children (< 15 years of age) in the households (HHs) that report spending more than 30 minutes collecting water, disaggregated by urban and rural residence; and b) estimate the absolute number of adults and children affected by water collection times greater than 30 minutes in 24 SSA countries.

METHODS: We analyzed data from the Demographic Health Survey (DHS) and the Multiple Indicator Cluster Survey (MICS) (2005-2012) to describe water collection labor in 24 SSA countries.

RESULTS: Among households spending more than …

Programme De Prise De Décision Entre L'Ergothérapeute Et Le Travailleur Ayant Une Incapacité Due À Un Trouble Musculosquelettique Persistant : Perspective Des Acteurs En Réadaptation, Marie-France Coutu, France Légaré, Marie-José Durand, Marc Corbière, Dawn Stacey, Lesley Bainbridge, Marie-Élise Labrecque

Rapports de recherche scientifique

Les travailleurs et les autres acteurs qui prennent des décisions en matière d’interventions de retour au travail ont souvent des intérêts et des buts différents. Le processus de prise de décision partagée (PDP) est une approche centrée sur la personne qui permet d’agir sur les écarts entre les travailleurs et les autres acteurs par rapport au but et au plan d’action à mettre de l’avant. À notre connaissance, un programme de PDP n'avait jamais été spécifiquement contextualisé en réadaptation au travail.

Ultimement, cette étude vise l’atteinte d’un but commun entre l’intervenant en santé et le travailleur dans le cadre de …

The “Burnout” Construct: An Inhibitor Of Public Health Action?, Bianchi Renzo, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

The prevention and treatment of the “burnout syndrome” within the critical care community is an important objective of the Moss et al. Burnout in the occupational area is based on the idea that burnout is especially common in individuals who care for critically ill patients. We think that the authors’ observations and recommendations are diminished by the fact that studies of burnout’s prevalence are methodologically problematic. The current definition and use of the burnout construct may in fact be detrimental to public health decision making.

Sécurité Des Machines : Expérimentation Pratique De Paramètres Et D’Outils D’Estimation Du Risque, François Gauthier, Yuvin Chinniah, Damien Burlet-Vienney, Barthélemy Aucourt, Stéphane Larouche

Rapports de recherche scientifique

Dans une démarche d’appréciation du risque telle que définie dans la norme internationale ISO 12100:2010, l’estimation du risque est une étape essentielle permettant aux concepteurs et aux utilisateurs de machines de déterminer le niveau de risque et les situations dangereuses les plus critiques. Deux études antérieures financées par l'Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) ont permis de révéler que les nombreux outils qui permettent de réaliser l’estimation du risque se présentent sous des formes très diverses, et que plusieurs de leurs caractéristiques (ex. : paramètres, architecture) pouvaient influencer de façon importante le …

Establishing Methodology For Occupational Injury Surveillance In Agriculture And Logging, Erika Elisabeth Scott

Legacy Theses & Dissertations (2009 - 2024)

Developing a low-cost surveillance system for occupational injury in agriculture and logging has long been a challenge. These data are needed to prioritize public health interventions in the agriculture and logging industries, and are crucial to evaluating changes in injury rates, as well as the effectiveness of safety interventions. Recently, the transition to electronic data reporting created new opportunities for the development of sustainable, low-cost surveillance systems. Pre-hospital care reports (PCR) and hospital data (emergency department, inpatient, and outpatient) are datasets of particular interest.

Workplace Violence, Organizational Culture, And Registered Nurses' Incident Reporting Patterns In Acute Hospitals In California, Feodora Jacobsen

Doctoral Dissertations

The purpose of this study was to increase understanding of the reporting patterns of WPV Type II in acute hospital settings. Although some patients are abusive toward nurses, that the abuse is underreported to hospital administrators. Qualitative studies identified common themes for underreporting including fear of being blamed, abuse considered part of the job, and not having sufficient time to fill out a formal report. This study is the first quantitative study to explore the changes in mean scores of organizational-culture factors under two mutually exclusive conditions: registered nurses (RNs) who do not report hospital incidents and RNs who do …

Développement D’Un Outil D’Analyse Du Risque Et De Catégorisation Des Interventions En Espace Clos, Yuvin Chinniah, Ali Bahloul, Damien Burlet-Vienney, Brigitte Roberge

Rapports de recherche scientifique

Au Québec, le Règlement sur la santé et la sécurité du travail (RSST) définit un espace clos à l’article 1 (ce projet a été mené avec la définition d’un espace clos applicable en 2016. Cette définition a été modifiée le 25 juillet 2023). Le travail en espace clos est une problématique qui concerne à la fois les secteurs municipal, manufacturier, chimique, militaire, agricole, de la construction et du transport. Les espaces clos parmi les plus courants en industrie sont les réservoirs, les silos, les cuves, les puits d’accès, les fosses, les égouts, les …

Évaluation De L’Efficacité D'Un Filtre N95 Contre Des Particules Ultrafines, Dont Les Nanoparticules, En Mode De Débits D'Air Constant Et Cyclique Simulant La Respiration Des Travailleurs, Ali Bahloul, Fariborz Haghighat, Reza Mostofi, Alireza Mahdavi, Claude Ostiguy

Rapports de recherche scientifique

On trouve des particules ultrafines (PUF), soit des particules dont le diamètre (D_p) est inférieur à 100 nm, dans de nombreux milieux de travail industriels, où leur inhalation peut, à long terme, causer de graves problèmes de santé. Dans certains contextes, les mesures d’ingénierie et les contrôles administratifs sont insuffisants pour protéger adéquatement les travailleurs contre l’exposition aux PUF. Un dispositif de protection personnel est alors requis, et les appareils de protection respiratoire à pièce faciale filtrante (APR) de type N95 sont ceux qu’utilisent le plus couramment les travailleurs de l’industrie et de la santé.

L'évaluation de l'exposition aux vibrations transmises au système main-bras et des lésions qui peuvent en résulter lors de l'utilisation d'outils portatifs motorisés repose actuellement sur les principes directeurs de la norme ISO 5349-1. Les dispositions de la norme ne tiennent pas compte, cependant, de l'effet des forces de couplage à l'interface main-poignée, alors que de nombreuses études ont démontré l'importance de ces forces dans la transmission des vibrations au système main-bras. Cela s'explique en partie par l'absence de méthodes pratiques pour mesurer ces forces sur le terrain, et en partie …

Conception Des Cordes D’Assurance Horizontales Pour La Protection Contre Les Chutes De Hauteur : Mise À Jour Du Guide Technique, Bertrand Galy, André Lan

Rapports de recherche scientifique

Les chutes de hauteur sont encore aujourd’hui une des causes majeures d’accidents du travail. Trop souvent, les travailleurs ne s’attachent pas, faute de point d’ancrage disponible, ou parce qu’ils trouvent que les points d’attache fixes restreignent trop leurs mouvements. Cette restriction peut toutefois être levée grâce aux systèmes de corde d’assurance horizontale (SCAH). Le présent rapport constitue la mise à jour du guide technique T-18 publié en 1991 et rend ce dernier caduc. Cette mise à jour était devenue nécessaire à la suite de l’introduction, en 2001, au Code de sécurité pour les travaux de construction (CSTC), de l’obligation d’équiper …

Solutions Visant L’Amélioration Des Conditions De Santé Et De Sécurité Des Poseurs De Revêtements De Sol, Monique Lortie, Sylvie Nadeau, Steve Vezeau

Rapports de recherche scientifique

La pose de revêtement de sol se divise en différentes spécialités : céramique, bois et revêtement souple. C’est ce dernier secteur qui nous intéresse, soit la pose de tapis (accrochés ou collés; en rouleau, en tuiles) ou de matériaux résilients (linoléum, vinyle, caoutchouc, gazon synthétique, etc.). Le métier de poseur de revêtement de sol est exigeant sur le plan physique (manutention de rouleaux très lourds, travail à genou prolongé, épandage de colle sur de grandes surfaces), mais aussi en matière de savoir-faire à développer. La pose exige de la précision, entre autres, pour ajuster les motifs et effectuer les raccords. …

Student Absenteeism And The Comparisons Of Two Sampling Procedures For Culturable Bioaerosol Measurement In Classrooms With And Without Upper Room Ultraviolet Germicidal Irradiation Devices, Chunxiao Su, Josephine Lau, Shawn G. Gibbs

Durham School of Architectural Engineering and Construction: Faculty Publications

Upper room ultraviolet germicidal irradiance (UVGI) has been shown to reduce the concentration of bioaerosols in controlled chambers. However, there is a lack of experimental results on the reduction of bioaerosol concentrations by UVGI devices in actual uncontrolled buildings. This study was carried out in an American elementary school in the Midwest. Two sampling procedures were carried out in six selected classrooms with similar dimensions that were separated into two groups: (1) UVGI exposure group and (2) non-UVGI control group. Two-stage Tisch culturable impactors were utilized to collect airborne culturable bacteria and fungi. Monthly samples were collected during unoccupied period …
