description: This study focuses on computer workers with repetitive strain injury (RSI) that lead to chronic pain, interference with daily activities (work and leisure), getting a night's sleep, and pain-related mental health issues (e.g., anxiety and depression). People take their hands for granted, and when they suddenly lose the use of them and are unable to perform basic daily activities (bathing, dressing, feeding ourselves), may develop anxiety and depression. This research examines how physical pain caused by RSI affects computer workers as a whole, and how workers use exercise/physical activity participation and health professionals use exercise/physical activity prescription to alleviate the accompanying pain, anxiety and depression, interviews were conducted with eight RSI-injured computer workers from the public service and eight health professionals who treat this type of injury. The results show that regular exercise/physical activity is seen to be a weapon in combating pain and pain-related mental health issues in RSI-injured computer workers. An improved understanding of the benefits of exercise/physical activity for RSI-injured computer workers living with chronic pain and pain-related mental health issues will provide them with more effective coping strategies, ameliorate their emotional/psychological recovery, facilitate their active return to the workforce, and enhance their overall quality of life.

description: Videoconferencing is becoming attractive for geographically distributed team collaboration. A 3D videoconference provides immersive telepresence and natural representation of all participants in a shared virtual meeting space to enhance quality of human-centered communication. In this thesis, an initial effort towards a 3D immersive teleconferencing system is presented, where the most advanced hardware and software technologies are applied, such as scene acquisition, modeling, rendering, tracking and stereo projective display. Especially the Exact Polyhedral Visual Hull algorithm has been used and proven to be robust for real-time 3D reconstruction. Customer--built polarization-multiplexed displays can provide a significant immersive impression. The Real-time Transport Protocol is employed for real-time communication. Performance analysis demonstrates that the implementation is a feasible framework towards the ultimate goal of 3D collaborative telepresence.
An empirical study of the effect of dogmatism and tenure status on educational innovativeness.
Creators: name: Fish, James C.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1975
Subjects: subject: Education, Educational Psychology.

description: The purpose of the thesis was to determine whether or not relationships exist among belief systems and tenure status of junior high school teachers in a metropolitan school system, and their attitudes toward educational innovation. On the basis of previous theory and research it was anticipated that closed and open personalities should differ in their receptivity toward educational innovation. It was also assumed that tenured and non-tenured teachers should differ in receptivity toward educational innovation. Specifically, the thesis was designed to investigate this question: Do dogmatism and tenure status of junior high school teachers influence their attitudes towards educational innovation? The following three statistical null hypotheses were developed to investigate the above question: (1) There are no statistically significant differences on resistance to educational innovation scores between open-minded teachers and closed-minded teachers. (2) There are no statistically significant tenure status differences related to resistance to educational innovation scores. (3) There is no statistically significant interaction effect between tenure status and dogmatism when the criterion is resistance to educational innovation. The sample for the study consists of 302 junior high school teachers in a large eastern metropolitan school system in the United States. The measuring instruments include the Educational Innovation Attitude Scale, the twenty-item Dogmatism Scale, and a Personal Data Form. The data were analyzed by analysis of variance techniques. Conclusions drawn from the data reveal that there were significant positive relationships between tenure status and resistance to educational innovation, and between closed-mindedness and resistance to educational innovation. It is also revealed that dogmatism-tenure status interactions were not significant on the resistance to educational innovation measure. The findings tend to support the independent nature of dogmatism and tenure status as significant predictors of resistance toward educational innovation. Furthermore, this study shows that tenure status and Rokeach's theory of dogmatism can be empirically defined and their effects on innovative behavior investigated. As a result of this study, the following are suggestions for further research: (1) That replicative studies with samples of teachers other than junior high school teachers be chosen from different school systems; (2) That further investigations of dogmatism and tenure status dimensions in relation to operative innovations be conducted; (3) That further examinations of the interaction of personality factors and environmental conditions in relation to innovativeness be made.

description: Objective: To evaluate the impact of using network meta-analysis (NMA) versus pair wise meta-analyses (PMA) for evidence synthesis on key outputs of cost-effectiveness analysis (CEA). Methods: We conducted Bayesian NMA of randomized clinical trials providing head-to-head and placebo comparisons of the effect of pharmacotherapies on the exacerbation rate in chronic obstructive pulmonary disease (COPD). Separately, the subset of placebo–comparison trials was used in a Bayesian PMA. The pooled rate ratios (RR) were used to populate a decision-analytic model of COPD treatment to predict 10-year outcomes. Results: Efficacy estimates from the NMA and PMA were similar, but the NMA provided estimates with higher precision. This resulted in similar incremental cost-effectiveness ratios (ICER). Probabilities of being cost-effective at willingness-to-pay thresholds (WTPs) between $25,000 and $100,000 per quality adjusted life year (QALY) varied considerably between the PMA- and NMA-based approaches. The largest difference in the probabilities of being cost-effective was observed at a WTP of approximately $40,000/QALY. At this threshold, with the PMA-based analysis, ICS, LAMA and placebo had a 43%, 30, and 18% probability of being the most cost-effective. By contrast, with the NMA based approach, ICS, LAMA, and placebo had a 56%, 19%, and 21% probability of being cost-effective. For larger WTP thresholds the probability of LAMA being the most cost-effective became higher than that of ICS. Under the PMA-based analyses the cross-over occurred at a WTP threshold between $60,000/QALY-$65,000/QALY, whereas under the NMA-based approach, the cross-over occurred between $85,000/QALY-$90,000/QALY. Conclusion: Use of NMAs in CEAs is feasible and, as our case study showed, can decrease uncertainty around key cost-effectiveness measures compared with the use of PMAs. The approval process of health technologies in many jurisdictions requires estimates of comparative efficacy and cost-effectiveness. NMAs play an increasingly important role in providing estimates of comparative efficacy. Their use in the CEAs therefore results in methodological consistency and reduced uncertainty.

description: Flood inundation mapping is a critical task for responding to the increasing risk of flooding linked to global warming. Significant advancements of deep learning in recent years have triggered its extensive applications, including flood inundation mapping. To cope with the time-consuming and labor-intensive data labeling process in supervised learning, deep active learning strategies are one of the feasible approaches. However, there remains limited exploration into the interpretability of how deep active learning strategies operate, with a specific focus on flood inundation mapping in the field of remote sensing. In this study, we introduce a novel framework of Interpretable Deep Active Learning for Flood inundation Mapping (IDAL-FIM), specifically in terms of class ambiguity of multi-spectral satellite images. In the experiments, we utilize Sen1Floods11 dataset, and adopt U-Net with MC-dropout. In addition, we employ five acquisition functions, which are the random, K-means, BALD, entropy, and margin acquisition functions. Based on the experimental results, we demonstrate that two proposed class ambiguity indices are effective variables to interpret the deep active learning by establishing statistically significant correlation with the predictive uncertainty of the deep learning model at the tile level. Then, we illustrate the behaviors of deep active learning through visualizing two-dimensional density plots and providing interpretations regarding the operation of deep active learning, in flood inundation mapping.

description: PLUMED is a plugin that can be used in tandem with a number of different molecular dynamics codes. The original paper on PLUMED was published 10 years ago and the code has had a success that we could not possibly have envisioned when we started writing it all those years ago. In this webinar I will discuss the sorts of calculations that can be done using PLUMED as well as how PLUMED came about and why we chose to write it the way that we did. I will then finish by discussing the recently formed PLUMED consortium and how we hope that PLUMED will evolve in the future.

description: Starting from a general transformation for spherically symmetric metrics where g\_11=-1/g\_00, we analyze coordinates with the common property of conformal flatness at constant solid angle element. Three general possibilities arise: one where tortoise coordinate appears as the unique solution, other that includes Kruskal-Szekeres coordinates as a very specific case, but that also allows other similar transformations, and finally a new set of coordinates with very different properties than the other two. In particular, this represents any causal patch of the spherically symmetric metrics in a compactified form. We analyze some relations, taking the Schwarzschild case as prototype, but also contrasting the cosmological de-Sitter and Anti-de-Sitter solutions for the new proposed pulsating coordinates.

Review of Next Generation Air Monitors for Air Pollution

description: Traditional air quality monitoring networks are the foundation for air quality management, policy and regulations, population exposure assessments and health effects research. With increasing awareness of spatial variability in air pollution concentrations within cities and the importance of pollution gradients from traffic and neighborhood sources, such as residential wood combustion, there is an increasing need to also evaluate air pollution variability at local or neighborhood scales. While passive sampler networks, mobile monitoring campaigns and the application of land use regression and dispersion models have provided useful information on air pollution spatial variability, none of the approaches can fully characterize both short-term temporal and spatial gradients in pollutant concentrations. Recently, there has been a proliferation of low-cost, low power, miniaturized, autonomous (and typically wireless) air quality monitoring units that have the potential to be applied in dynamic dispersed high resolution air quality monitoring networks and to be used in "Citizen Science" applications. In this report we review new air quality monitoring technologies and discuss their use in the context of conventional monitoring and new applications. We summarize information on sensor performance and provide recommendations regarding future applications.

Three-dimensional modeling based on disparity estimation for image-based virtual environments
Creators: name: Huang, Xiaodong
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis addresses the challenging problem of obtaining 3D models for real environments from stereo images and translational video sequences. The problem is partitioned into two main parts: matching and disparity estimations to obtain depth maps and separate 3D models for different image locations, and the combining of these separate 3D models into one 3D model for the whole environment. Solutions are proposed dealing with these two main issues respectively, and the results from implementing these solutions are also presented. The novelty for the solution of the first part -- which deals with the matching problem -- lies in the fact that it combines the pixel-based approach and region-based approach. A hybrid algorithm is developed for disparity estimation between stereo images and translational video sequences, so that some intrinsic problems in the pixel-based and region-based approaches (like the detection of sky) can be solved in a combined way while keeping the object boundaries sharp and crisp, and hence give disparity and depth maps which are qualitatively better than traditional methods. The novelty for the solution of the second part -- which deals with the integration of separate 3D models from different image locations -- comes from the usage of region information obtained from the disparity estimation process, the estimation of ego-motion parameters, as well as to the integration of the object surfaces from different 3D models. For the ego-motion estimation, instead of using the bundle adjustment or iterative closest points (ICP) which perform the estimation in 3D space, our algorithm uses large regions with correspondence information in each image to determine the homogeneous transformations in image space. For the integration of separate 3D models, these large regions from different models are also used to adjust and expand the shape of regions which belong to the same surfaces, so that even the occluded surfaces in one image location can be filled by integration of surfaces from other images. The results are shown with the image rendering at novel viewpoints as well as with PSNR values measured between the rendered images and existing images at real image locations.
Identification of heme- and hemoglobin-binding proteins in Trichomonas vaginalis

description: Trichomonas vaginalis is the cause of human trichomoniasis. Although acquisition of iron by binding to host hemoglobin through distinct receptor(s) has been described in this parasite, no specific hemoglobin-binding site has been reported. Our hypotheses were: (1) hemolytic activity of T. vaginalis isolates correlates with the virulence, and (2) T. vaginalis binds hemoglobin through a specific surface receptor. The in vitro hemolytic activities of four T. vaginalis strains were examined. No correlation between hemolytic activity and virulence in different isolates was found. Using hemoglobin-affinity chromatography, two protein bands of approximately 48 and 63 kDa were detected, the former binds preferentially to heme. Mass spectral analysis indicated that the 48- and 63-kDa proteins had significant homology with the subunits of two T. vaginalis adhesins: AP51 and AP65, respectively. This study confirms the existence of multifunctional proteins in T. vaginalis, which enable the parasite to survive in a constantly changing environment like human vagina.

description: This paper applies a panel structural VAR model to uncover both the dynamics and inter-product/market differences in responses of product quality to real exchange rate (RER) shocks with complete data of China’s monthly agricultural exports. It finds that RER appreciations promote the quality of China’s agricultural exports on average in contrast to discouraging exports, but the effect is mostly short-run—the average response peaks in the immediate month after the shock and phases out in three months. Following domestic price and quality itself, RER shocks account for 3% on average in quality variations as the third contributor. The quality response to RER shocks, however, substantially differs across both products and markets.
Physiological causes and consequences of social status in rainbow trout (Oncorhynchus mykiss)

description: A number of social and behavioural traits inherent to the individual are known to influence the outcome of social interactions in salmonid fish. In addition, recent work has raised the possibility that the prior physiological condition of a fish may predetermine its social status. Therefore, the hypothesis that elevated plasma cortisol levels influence social rank was tested, with the prediction that rainbow trout (Oncorhynchus mykiss) treated with cortisol would be relegated to subordinate social status in pairwise contests with an untreated conspecific. Experimental elevation of plasma cortisol significantly increased the probability that the treated fish within each pair became subordinate, an effect later identified as cortisol specific, as it was abolished by simultaneous treatment with the glucocorticoid receptor antagonist, RU486. One possible mechanism through which cortisol could exert this effect was subsequently investigated, namely that cortisol influenced social status through behavioural modifications mediated by changes in brain monoaminergic activity.

description: A high temporal resolution pollen diagram from a lake in the middle-Arctic region of the Boothia Peninsula, Nunavut, Canada, documents the history of the regional vegetation and climate for the past 7200 years. A diatom sequence had been previously prepared from this core. Major tundra pollen taxa in the core include Cyperaceae and Salix, with Cyperaceae comprising over 50% of the pollen in the early and late Holocene. Tree pollen, transported from far to the south, comprised a large percentage of the pollen sum, with Pinus accounting for 30% of the pollen in some levels of the core. Pollen percentages and concentrations of taxa typical of the middle-Arctic were highest in the mid-Holocene, corresponding to warm conditions. Decreasing pollen concentrations indicate cooling temperatures, with more rapid decreases occurring around 4200, 3800-3400, and 2500 cal yr BP. Pollen percentages of Salix, Cyperaceae, and Artemisia increased in the past 35 years in response to global warming. Reconstructions of July temperature using the modern analog technique showed the mid-Holocene (5800-2800 cal yr BP) was approximately 1°C higher than during the past 1000 years.
Young pregnant women's discursive constructions of the body and health

description: The purpose of this thesis was to explore young pregnant women's discursive constructions of the pregnant body and health in the context of the dominant obesity discourse. Conversations with 15 young pregnant women from the Ottawa area were tape-recorded, transcribed, and then analyzed using a thematic and feminist poststructuralist discourse analysis. The results were divided into two articles, the first discussing the women's constructions of health during pregnancy and the second, their constructions of the pregnant body. The narratives reveal that overall the women constitute themselves as neoliberal subjects reproducing dominant patriarchal discourses (e.g., obesity, personal and moral responsibility for health, femininity). Paradoxically, many of these women also show awareness of the contradictions between dominant health and bodily discourses and personal experience, thus leading to alternative and more disruptive subject positions. Impacts, implications, and future research directions are discussed.

description: We statistically evaluate and compare four orbital similarity criteria within five-dimensional parameter space ($D_{SH}$, $D_D$, $D_H$, and $\varrho_2$) to study dynamical associations using the already classified meteors (manually by a human) in CAMS database as a benchmark. In addition, we assess various distance metrics typically used in Machine Learning with two different vectors: ORBIT, grounded in heliocentric orbital elements, and GEO, predicated on geocentric observational parameters. Additionally, we compute the optimal cut-offs for all methods for distinguishing sporadic background events. Our findings demonstrate the superior performance of the sEuclidean metric in conjunction with the GEO vector. Within the scope of D-criteria, $D_{SH}$ emerged as the preeminent metric, closely followed by $\varrho_2$. $\varrho_2$ stands out as the most equivalence to the distance metrics when utilizing the GEO vector and the most compatible with GEO and ORBIT simultaneously, whereas $D_D$ aligns more closely when using the ORBIT vector. The stark contrast in $D_D$'s behavior compared to other D-criteria highlights potential inequivalence. Geocentric features provide a more robust basis than orbital elements for meteor dynamical association. Most distance metrics associated with the GEO vector surpass the D-criteria when differentiating the meteoroid background. Accuracy displayed a dependence on solar longitude with a pronounced decrease around 180$^\circ$ matching an apparent increase in the meteoroid background activity, tentatively associated with the transition from the Perseids to the Orionids. Considering lately identified meteor showers, $\sim$27\% of meteors in CAMS would have different associations. This work unveils that Machine Learning distance metrics can rival or even exceed the performance of tailored orbital similarity criteria for meteor dynamical association.

Structured lighting stereoscopy with marching pseudo-random patterns

Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis discusses the development of a 3D reconstruction system based on active stereoscopy with structured lighting. The proposed system accomplishes 3D reconstruction of objects using a combination of spatial-neighboring and time-multiplexing structured light patterns encoded with pseudo-random codes. This combination builds upon the concept of marching patterns that can adaptively increase the reconstruction resolution on demand. Original techniques are introduced to recover and validate pseudo-random codes from images using a combination of image processing algorithms. The validation of codes is performed such that potential outliers are minimized and the density of 3D point clouds remains fairly high in the models. Finally, the system simultaneously provides models with color and texture mapping using linear interpolation between vertices which enables a more accurate and intuitive representation of 3D objects. Experimental results presented demonstrate the various reconstruction densities possible with the proposed approach, its performance on objects with different surface properties, and the quality of the colored 3D models achieved.

description: In this thesis, I focus on Southern African peer educators' experiences in facilitating HIV/AIDS education activities within the Kicking AIDS Out network. By utilizing Foucault's (1975) conception of "subjugated knowledges," I work towards four main objectives. In chapter one, I aim to surface a sample of young people's subjugated knowledges pertaining to the "lack of evidence" discourse of sport for development. In chapter two, my objective was to understand better what tools peer educators need to be more effective in their HIV/AIDS education efforts in a sport environment. Chapter three suggests steps to encourage knowledge exchange on sport for development across geographical and cultural boundaries to further national HIV/AIDS education and health goals with Aboriginal communities. I meet my fourth objective, to provide recommendations to the Kicking AIDS Out network regarding the training and support needs of peer educators in a field report, which is not contained in this thesis.

description: The thesis investigates the design, fabrication, and experimental demonstration of a photodetector integrated into a thin metal stripe waveguide of finite width, operating at optical infrared wavelengths. The metallic stripe, which is clad by lightly doped silicon at the bottom and air on the top, supports the propagation of bound optical modes having very high loss (∼ 1dB/mum) and submicron field confinement in the axis perpendicular to the stripe width. The metal/silicon interface also has electrically rectifying characteristics, formally described as a Schottky diode. The theoretical model for the electrical performance of the photodiode is combined with a numerical study of the optical modes supported by the waveguide, and used to present theoretical performance predictions. A few designs are fabricated on a silicon wafer and tested experimentally, with successful demonstration of photodetection. The device has promise for applications in short-range optical interconnects, integrated optics, and silicon based photonic circuits.

description: Background Despite the growing prevalence of illicit stimulant drug use internationally, and the widespread involvement of people who inject drugs (IDU) within street-based drug markets, little is known about the impact of different types of street-based income generation activities on the cessation of stimulant use among IDU. Methods Data were derived from an open prospective cohort of IDU in Vancouver, Canada. We used Kaplan-Meier methods and Cox proportional hazards regression to examine the effect of different types of street-based income generation activities (e.g., sex work, drug dealing, and scavenging) on time to cessation of stimulant use. Results Between December, 2005 and November, 2012, 887 IDU who use stimulant drugs (cocaine, crack cocaine, or crystal methamphetamine) were prospectively followed-up for a median duration of 47 months. In Kaplan-Meier analyses, compared to those who did not engage in street-based income generation activities, participants who reported sex work, drug dealing, scavenging, or more than one of these activities were significantly less likely to report stimulant drug use cessation (all p<0.001). When considered as time-updated variables and adjusted for potential confounders in a multivariable model, each type of street-based income generation activity remained significantly associated with a slower time to stimulant drug cessation (all p<0.005). Conclusions Our findings highlight the urgent need for strategies to address stimulant dependence, including novel pharmacotherapies. Also important, structural interventions, such as low-threshold employment opportunities, availability of supportive housing, legal reforms regarding drug use, and evidence-based approaches that reduce harm among IDU are urgently required.

description: Recent events including deliberate attacks and accidental explosions have highlighted the need for greater research in structural response to blast loading. One of the primary research focuses has been on the prevention of progressive collapse of structures. The response of vertical load transferring members, such as columns, is of particular importance to progressive collapse prevention. In order to understand and predict the behaviour of the global structure during and after a blast loading event, a greater understanding of column behaviour must be developed. Currently there is a limited amount of experimental test data available on the response of reinforced concrete columns exposed to blast loads. This thesis presents the results of experimental research involving tests of scaled reinforced concrete columns exposed to shock wave induced impulsive loads using the University of Ottawa Shock Tube. A total of 14 half scale reinforced concrete columns were constructed and tested under blast pressures. The columns were designed according to Canadian Standard Association (CSA) Standard A23.3 for the "Design of Concrete Structures" (2006) standard as first story columns for both seismic and non-seismic regions. Axial load was applied to levels similar to what can be expected in actual structures. The columns were exposed to various pressure-impulse combinations which resulted in a range of column response. Comparisons are made between seismically designed and detailed columns and those that represent non-seismic gravity load columns in terms of displacement under similar shockwave loading. In addition, numerical analyses were conducted using single degree of freedom dynamic analysis. The numerical analysis accounts for the loss of axial load observed with horizontal displacement, strain rate effects on material strengths, the formation of plastic hinges in the column near the supports and at mid-height and the corresponding change in resistance and the response mode shape. The numerical analysis is validated with the experimental results and proven to accurately predict displacement of reinforced concrete columns under shock wave loading. The results indicate that an equivalent single degree of freedom model may be used to determine the response of a column under air blast induced shock loading if proper displacement-resistance models that account for material strength increase factors and change in axial load are used.

description: Entre 1914 et 1919, pres de 2500 infirmières militaires ont servi outre-mer au sein du Service de santé de l'armée canadienne. Ces femmes ont cotoyé la mort au quotidien. Elles ont soigné les soldats criblés de blessures, les ont réconfortés, les ont supportés moralement. Actrices essentielles des hopitaux généraux et fixes, l'expérience et le vécu des infirmières militaires canadiennes de la Grande Guerre ont récemment fait l'objet de recherches approfondies. En revanche, très peu d'études ont exploré les trajectoires d'après-guerre de ces infirmières. Notre thèse comble cette lacune et révèle que les infirmières militaires de la Grande Guerre ont apporté une contribution significative non seulement à l'effort de guerre, mais aussi à la société civile de l'entre-deux-guerres. Pour le démontrer, nous avons reconstruit la trajectoire d'après-guerre de 422 infirmières militaires canadiennes diplomées des écoles de formation en soins infirmiers de Toronto et de Montréal. Munies d'un statut particulier, d'un réseau de contacts établis outre-mer, de savoirs et de compétences qui les démarquent de leurs collègues civiles et profitant d'opportunités éducatives sans précédent, plusieurs infirmières vétérans se bâtissent de fructueuses carrières. Dans l'entre-deux-guerres, 42 d'entre elles occupent les postes limités de responsabilité dans des hopitaux et des écoles de formation en soins infirmiers du Canada, des États-Unis et d'ailleurs. D'autres, qui se sont spécialisées dans les soins infirmiers chirurgicaux, la diététique, la radiologie et l'anesthésie durant la guerre, transfèrent ces connaissances et ces habiletés dans les établissements de santé civils. L'accès privilégié aux formations supérieures en hygiénisme et en travail social permet aussi à des infirmières vétérans de contribuer pleinement à l'essor des soins infirmiers hygiénistes et du service social en santé. Même celles qui optent pour le mariage et la maternité trouvent des façons de s'engager socialement, généralement à travers l'action bénévole. En examinant les trajectoires d'après-guerre de 422 infirmières vétérans, nous usons d'un angle novateur pour dévoiler une partie de l'héritage légué par ces actrices de la Grande Guerre.

description: The present study aims to analyze the environmental certification process in the context of the Agro Industrial System (SAG) of beef production in Brazil through mapping and promulgations. This research become relevant as environmental certifications attest to the implantation of a practical process of environmental management in participating organizations that vision the philosophy of Sustainable Development. Approaches to this qualitative analysis were: Sustainable Development, Environmental Management, Environmental Certification, The Stakeholders Theory and SAG. Semi structured interviews were conducted with those responsible for certification processes in organizations related to agribusiness. Findings show that, in each of these organizations, environmental management was well structured which facilitated the process of certification as most of the requisites had been met economically, environmentally, and socially. It was observed that, in Brazil, the certification process is advancing in the SAG of the beef cattle culture.

description: Objective Despite emerging evidence of a significant adverse relationship between food insecurity and sexual risk-taking, data have been primarily derived from resource-constrained settings and HIV-negative populations. To our knowledge, this study is the first to longitudinally evaluate the relationship between food insecurity and unprotected sex among HIV-seropositive people who inject drugs [injection drug users (IDUs)] both on and not on HAART. Design Longitudinal analyses were restricted to HIV-positive IDUs who completed baseline and at least one follow-up visit in a prospective cohort (AIDS Care Cohort to evaluate Exposure to Survival Services, 2005–2009). Methods We constructed a multivariate logistic model using generalized estimating equations (GEEs) to assess an independent relationship between severe food insecurity (e.g., hunger due to lack of access or means to acquire food) and unprotected vaginal/anal sex. Results Among 470 HIV-positive IDUs, the median age was 42 years (interquartile range 36–47) with 61% men and 39% women. The prevalence of severe food insecurity was 71%, with no differences by HAART use. Severe food insecure IDUs were marginally less likely to have a suppressed HIV-1 RNA viral load (31 vs. 39%, p=0.099). In multivariate GEE analyses, severe food insecurity [adjusted odds ratio=2.68, 95% confidence interval 1.49–4.82] remained independently correlated with unprotected sex among HIV-positive IDUs, controlling for age, sex/gender, married/cohabitating partner, binge drug use, homelessness, and HAART use. Conclusion These findings highlight a crucial need for structural HIV interventions that incorporate targeted food assistance strategies for IDUs. Given recent evidence of poor virological response among food insecure individuals on HAART, innovative HIV care models should integrate targeted food security programs and early access to HAART.
