Estudos de coeficiente de partição mostram que o valor de Kp do metal pode variar ordens de grandeza conforme as características físico-químicas do solo. Portanto, o Kp é um parâmetro sensível no modelo de avaliação de risco à saúde humana, e normalmente é um valor nominal adotado por agências ambientais que pode não representar adequadamente o solo em estudo e implicar erros no cálculo do risco. Este trabalho tem como objetivos: avaliar a contaminação do solo adjacente à usina termoelétrica de Figueira por metais tóxicos; determinar o Kp dos metais As, Cd, Co, Cr, Cu, Mo, Ni, Pb e Zn no solo pela razão entre a concentração do metal obtida por digestão com HNO3 concentrado e a concentração do metal obtida por extração com EDTA 0,05 mol L-1 (KpEDTA) ou Ca(NO3)2 0,1 mol L-1 (KpCa(NO3)2); e avaliar a influência do uso dos diferentes valores de Kp no modelo de avaliação de risco à saúde humana C-Soil no cálculo do risco. As principais conclusões foram: os metais contaminantes do solo de Figueira foram As, Cd, Mo, Pb e Zn, e o As foi o elemento mais crítico; tanto o valor de KpCa(NO3)2 quanto o de KpEDTA poderiam ser utilizados no cálculo do risco à saúde humana, no caso de Figueira, exceto para o Pb...

Nos primeiros anos de 2000, as áreas contaminadas emergiram como motivo de preocupação para a sociedade paulista, configurando-se como problema de ordem ambiental, sanitária e urbanística. Para além do factual, as áreas contaminadas se mostram fenômenos representativos e simbólicos de um modo histórico de produção e reprodução do capital de bases urbanas e fabris. Elas são expressão tardia de um modelo de desenvolvimento extremamente agressivo, cujas manifestações mais agudas se dão nas cidades. Nas tensões e contradições que marcam as paisagens urbanas contemporâneas, apresentam-se perturbadas as condições de se promover saúde. Uma das razões do negar saúde nas cidades é o modo como nelas se fez uso da química para produzir mercadorias de toda ordem, entendendo-se que, por muito tempo, a confiança na química foi extensão direta da confiança no progresso. A Região Metropolitana de São Paulo (RMSP), onde historicamente ocorreram processos acelerados de urbanização e concentração de população, é emblemática da distribuição desigual dos proveitos e dos rejeitos da grande maquinaria de produção que caracteriza a sociedade racional moderna. Nela se fomentam riscos e angústias derivadas da espoliação social e da exposição humana a toda sorte de rejeitos da civilização moderna. Na RMSP estão atualmente cadastradas 1254 áreas contaminadas...

A contaminação dos solos por elementos potencialmente tóxicos (EPTs) provoca alterações na estrutura e no funcionamento dos ecossistemas, além de oferecer riscos à saúde pública. Os EPTs estão presentes naturalmente no ambiente, sendo constituintes de rochas e sedimentos. Entretanto, atividades antropogênicas como emissões industriais, uso de efluentes urbanos, dejetos de animais, biossólidos, fertilizantes e defensivos agrícolas podem contribuir para aumento da concentração dos EPTs. O solo é um dos principais meios de exposição dos EPTs aos seres humanos. Logo, é importante quantificar os teores dos EPTs nos solos e sua distribuição na microbacia para poder avaliar o risco a saúde humana. Os efeitos dos elementos tóxicos que chegam ao solo sobre a diversidade e funcionalidade da biota podem ser avaliados por meio de testes ecotoxicológicos. Alguns organismos são bons indicadores ambientais por participarem de processos biológicos importantes do solo. Os principais organismos utilizados são os colêmbolos, artrópodes terrestres com alta diversidade e abundância, sendo encontrado em todos os biomas. Nesse estudo, quantificaram-se os teores de Arsênio (As), Cádmio (Cd), Cobalto (Co), Cobre (Cu), Cromo (Cr)...

Aadversidade durante a infância tem sido um dos temas alvo de numerosos estudos no âmbito da Psicologia, devido à sua prevalência e ao forte impacto no desenvolvimento do indivíduo. Os resultados mais prevalentes vão de encontro ao facto das experiências adversas durante a infância aumentarem o risco de perturbações físicas e psicológicas na idade adulta. Utilizando o Questionário Sócio-demográfico e História de Vida e o Brief Symptons Inventory procuramos caracterizar as experiências adversas durante a infância e relacionar a adversidade com comportamentos de risco para a saúde e com sintomas de psicopatologia, em 42 mulheres reclusas num estabelecimento prisional do norte do país. A maioria das mulheres relata um quadro complexo de diversas experiências adversas durante a sua infância. Num total possível de dez categorias de adversidade, verificamos uma média de adversidade total de 5.05 (DP=2.63), assim como uma elevada prevalência de comportamentos de risco para a saúde e de sintomatologia psicopatológica. Os resultados indicam uma forte relação entre adversidade e sintomas psicopatológicos, e várias relações entre adversidade e comportamentos de risco para a saúde.As mulheres detidas viveram um elevado número de experiências adversas durante a infância e...

BACKGROUND—A factory fire in Tranmere, Merseyside, England, deposited asbestos containing fallout in an urban area. There was considerable community anxiety for months after the incident. Therefore an assessment of the long term health risks of this acute environmental incident were requested by the local health authority.
METHODS—The facts of the incident were gathered and appraised from unpublished and press reports, involved personnel, and further analysis of material collected at the time of the incident. The literature on the long term health risks of asbestos was reviewed, and combined with evidence on asbestos exposure to estimate community health risk.
RESULTS—Risk was almost entirely from exposure to fire fallout of chrysotile in asbestos bitumen paper covering the factory roof. Amosite was only detected in a few samples and in trace amounts. The number of people who lived in the area of fallout was 16 000 to 48 000. From a non-threshold model with assumptions likely to overestimate risk, the lung cancer risk is estimated to be undetectably small. Risk of mesothelioma from chrysotile exposure, and risks of lung cancer and mesothelioma from amosite exposure were based on observational studies and were estimated to be even lower than that of lung cancer risk from chrysotile exposure. Academically...

Thesis (Ph.D.)--University of Rochester. School of Nursing. Dept. of Nursing, 2010.; Currently, few structured self-report instruments that may be used for collecting data from adolescents who are deaf exist for the purposes of public health surveillance or research. The development of structured self-report instruments that allow adolescents who are deaf to communicate health-related information in a manner that protects their identity or provides them with anonymity is critical to the success of conducting health-related research with this population. In order to conduct research that is essential to identifying and addressing the health needs and risks of persons deaf since childhood, investigative studies to address this critical barrier to progress in the field of Public Health Research are necessary. Quantitative health-related research (HRR) can be used to systematically identify and measure the health-related issues of early-deafened persons (EDPs) that are deemed to exist based on qualitative health research and anecdotal clinician reports. However, conducting quantitative HRR with EDPs is challenging because there are issues related to communication and language that threaten the rigor and control required of sound systematic research. To conduct sound quantitative investigations with EDPs...

Non-communicable diseases (NCDs) represent an important and growing burden to the health and economies of the Latin America and the Caribbean (LAC) region. However, some of this burden can be prevented or controlled through targeted clinical services and multi-sectoral activities aimed at improving diet, promoting physical activity, and reducing tobacco use and alcohol abuse. This study focuses on population-wide, multi-sectoral interventions to prevent risk factors for NCDs. This study seeks to answer the following questions: what is the health and economic burden of NCDs in the region?; what are countries doing to promote healthy living and prevent risk factors for NCDs?; what are the main governance challenges countries face in developing and implementing population-wide NCD prevention interventions and which are the success stories?; and what else can the region do to reduce health risk factors and prevent the onset of NCDs? This study documents governance challenges in the design and implementation of promising or successful population-wide interventions intended to prevent health risk factors in LAC. It focuses on the process whereby public officials develop and implement primary-prevention policies and programs. It is composed of five commissioned case studies on multi-sectoral interventions to promote healthy living in the region. These case studies examine which stakeholders participated directly or indirectly in the decision-making process; what positions they held; which incentives they faced; which strategies they pursued; how did existing institutional arrangements affect the decision-making process; what lessons can be drawn from these processes; and what were the successes and setbacks? This report provides a glimpse into the types of opposing interests and power games involved in proposing...

Adolescents engage in a range of risk behaviors during their transition from childhood to adulthood. Identifying and understanding interpersonal and socio-environmental factors that may influence risk-taking is imperative in order to meet the Healthy People 2020 goals of reducing the incidence of unintended pregnancies, HIV, and other sexually transmitted infections among youth. The purpose of this study was to investigate gender differences in the predictors of HIV risk behaviors among South Florida youth. More specifically, this study examined how protective factors, risk factors, and health risk behaviors, derived from a guiding framework using the Theory of Problem Behavior and Theory of Gender and Power, were associated with HIV risk behavior. ^ A secondary analysis of 2009 Youth Risk Behavior Survey data sets from Miami-Dade, Broward, and Palm Beach school districts tested hypotheses for factors associated with HIV risk behaviors. The sample consisted of 5,869 high school students (mean age 16.1 years), with 69% identifying as Black or Hispanic. Logistic regression analyses revealed gender differences in the predictors of HIV risk behavior. An increase in the health risk behaviors was related to an increase in the odds that a student would engage in HIV risk behavior. An increase in risk factors was also found to significantly predict an increase in the odds of HIV risk behavior...

BACKGROUND: Social and environmental changes have accompanied the ongoing rapid urbanisation in a number of countries during recent decades. Understanding of its role in the health-risk transition is important for health policy development at national and local level. Thailand is one country facing many of the health challenges of urbanisation. OBJECTIVE: To identify potential associations between individual migration between rural and urban areas and exposure to specific social, economic, environmental and behavioural health determinants. DESIGN: Baseline data from a cohort of 87,134 Thai open university students surveyed in 2005 (mean age 31 years). Four urbanisation status groups were defined according to self-reported location of residence (rural: R or urban: U) in 2005 and when the respondent was 10 12 years old (yo). RESULTS: Fourty-four percent were living in rural areas in 2005 and when they were 10 12yo (Group RR: ruralites); 20% always lived in urban areas (UU: urbanites); 32% moved from rural to urban areas (RU: urbanisers); 4% moved in the other direction (UR: de-urbanisers). The ruralites and urbanites often were the two extremes, with the urbanisers maintaining some of the determinants patterns from ruralites and the deurbanisers maintaining patterns from urbanites. There was a strong relationship between urbanisation status...

Background: Accurate monitoring of health conditions and behaviours, and health service usage in the population, using an effective and economical method is important for planning and evaluation. This study examines the reliability of questions asked in a telephone survey by conducting a test/retest analysis of a range of questions covering demographic variables, health risk factors and self-reported chronic conditions among people aged 16 years and over. Methods: A Computer Assisted Telephone Interviewing (CATI) survey on health issues of South Australians was re-administered to a random sub-sample of 154 respondents between 13-35 days (mean 17) after the original survey. Reliability between questions was assessed using Cohen’s kappa and intraclass correlation coefficients. Results: Demographic questions (age, gender, number of adults and children in the household, country of birth) showed extremely high reliability (0.97 to 1.00). Health service use (ICC = 0.90 95% CI 0.86-0.93) and overall health status (Kappa = 0.60 95% CI 0.46-0.75) displayed moderate agreement. Questions relating to self-reported risk factors such as smoking (Kappa = 0.81 95% CI 0.72-0.89) and alcohol drinking (ICC 0.75 = 95% CI 0.63-0.83) behaviour showed good to excellent agreement...

Self-presentation has been identified as playing a key role in the perfonnance of various potentially hazardous health behaviours such as substance abuse, eating disorders and reckless behaviours (Leary, Tchividjian, & Kraxberger, 1994; Martin & Leary, 2001; Martin, Leary, & O'Brien, 2001). The present study investigated the role of selfpresentation on adolescent health-risk behaviours. Specifically, this study examined the prevalence of adolescent identified health-risk behaviours rooted in self-presentational motives in youths aged 13-18 years. The current study also identified the specific images associated with these behaviours desired by youth, and the targets of these behaviours. Also, the relationship between these behaviours, and several trait measures (social physique anxiety, public-self consciousness, fear of negative evaluations, selfpresentational efficacy) of self-presentation were examined. Finally, the gender differences in health risk behaviours and self-presentational concerns were examined. Participants in the present study were 96 adolescent students, 34 male and 62 female, recruited from various private schools across Southern Ontario. Students ranged in age from 13 to 18 years for both males (M age = 15.81 years...

Este artigo versa sobre contribuições da teoria social a um estudo sobre o risco à saúde humana e ao ambiente, desenvolvido entre 2003 e 2005 em área urbana contaminada, localizada no bairro Vila Carioca, no sudeste do município de São Paulo, Brasil. Resíduos perigosos provenientes de processo produtivo do setor químico, dispostos inadequadamente na localidade ao longo do tempo, resultaram em contaminação ambiental, cujos efeitos representam riscos à saúde da população local. A investigação foi realizada com o objetivo de identificar interpretações sociais sobre o conceito de situação de risco, condizentes com concepções incorporadoras da dimensão social do risco e voltadas à melhoria das condições de saúde ambiental. Utilizou-se metodologia qualitativa de pesquisa, alicerçada na teoria social, e instrumentos variados de coleta de dados. Os resultados apontaram interpretações sociais diferenciadas sobre o conceito de situação de risco, sugerindo diversidade de concepções entre a população pesquisada a respeito dos problemas ambientais e de saúde que os atingiam. Neste artigo, apresentam-se fundamentos do enfoque do risco, na teoria social e na obra de Ulrick Beck sobre sociedade de risco, a fim de conferir suporte teórico à interpretação dos dados coletados em campo.

Health impact assessment (HIA) and comparative risk assessment (CRA) are important tools with which governments and communities can compare and integrate different sources of information about various health impacts into a single framework for policy-makers and planners. Both tools have strengths that may be combined usefully when conducting comprehensive assessments of decisions that affect complex health issues, such as the health risks and impacts of transport policy and planning activities. As yet, however, HIA and CRA have not been applied widely to the area of transport. We draw on the limited experience of the application of these tools in the context of road transport to explore how comparative assessment of transport risks can contribute to HIA of transport policies.

Objective: To examine agreement between patients' self-report and general practitioners' perception of their patients' health risk status and screening history. Methods: Patients attending an Aboriginal Community Controlled Health Service self-reported via survey their health risk status and screening history, while waiting to see their general practitioner (GP). Following the consultation the GP completed a corresponding survey. Prevalence rates and rates of agreement using the kappa statistic were calculated for both self-reported and GP-reported risk status for smoking, at-risk alcohol consumption and physical inactivity; and screening history for blood pressure, cholesterol, diabetes and cervical cancer. Results: Prevalence rates of health risks were similar from self-report versus GP-reported, yet differed on screening history. Patients who identified themselves as being at risk were often not the same as those identified by GPs. Agreement between patient and doctor was substantial for smoking, yet poor for at-risk alcohol consumption and physical inactivity. Agreement was fair for cholesterol and cervical cancer screening, and slight for blood pressure and diabetes screening. Conclusions and implications: This study suggests that for effective preventive care...

Objective:- To compare the performance of two new approaches to risk adjustment that are free of the influence of observational intensity with methods that depend on diagnoses listed in administrative databases. Setting:- Administrative data from the US Medicare program for services provided in 2007 among 306 US hospital referral regions. Design:- Cross sectional analysis. Participants:- 20% sample of fee for service Medicare beneficiaries residing in one of 306 hospital referral regions in the United States in 2007 (n=5 153 877). Main outcome measures:- The effect of health risk adjustment on age, sex, and race adjusted mortality and spending rates among hospital referral regions using four indices: the standard Centers for Medicare and Medicaid Services—Hierarchical Condition Categories (HCC) index used by the US Medicare program (calculated from diagnoses listed in Medicare’s administrative database); a visit corrected HCC index (to reduce the effects of observational intensity on frequency of diagnoses); a poverty index (based on US census); and a population health index (calculated using data on incidence of hip fractures and strokes, and responses from a population based annual survey of health from the Centers for Disease Control and Prevention).

Benzene is a constituent of oil regarded as a potential carcinogen, and therefore a dangerous compound. Its risk increases when spills occur, added to the effect of gravity and high mobility, it's infiltrated into the ground, reaching the phreatic area until dissolved, contaminating the water. The objective of this research was to evaluate the health risk of environmental liabilities caused by the contamination with benzene in the "Ex-refinery March 18" in Mexico City. For twenty years were carried out remediation work -which started since 2008- and today this space has been converted into a recreational park. This environmental liability is divided into seven zones for purposes of remediation, although in this case only was considered the 7 zone. It also, took into account only the concentration of this hydrocarbon (average, percentil 75 and 95) present in the soil. The results, -from a total of 642 samples from 122 soil profiles-, before the remediation -biospray with vapor extraction-, showed a health risk by depth between 1.2 to 7.2 m, from 1.69E-07 to 1.2 1.25E-05 m to 4.8 m, which coincides with the phreatic level of aquitard, was the place where the highest level of health risk is present. After remediation, the measurements yielded 4.07E-07 to 1.2 m and 3.85E-07 to 4.8 m. These values indicate that the mass of benzene before decontamination exceeded the risk considered acceptable...

This pilot study was an approach to determine the health outcomes (nutritional status, cognitive status, mental health and educational status), and the presence of health risk behaviors (aggressive behavior/ delinquency, hazardous/harmful drinking, substance use/abuse and tobacco use) of adolescents who have been exposed all their lives to lead. Besides, we could identify individual, familial and social factors, such as lead exposure, that were related to them. The sample included 40 adolescents (25 females and 15 males), aged 12-19 years, who participated as children in the Childhood Lead Exposure Surveillance Program (CLESP), conducted in a metallurgical area of Mexico. The 100% of the participants were reported neurologically healthy by medical clinical examination. The 15% were below 70 points of the Full Scale Intelligence Quotient, higher than the expected percentage in the general Mexican population. Moreover, we detected the presence of health risk behaviors. The protective factors identified were mean cell volume, adolescent education, father education and living in an apartment. Risk factors identified were: sleep hours, mono-parental family, positive family history of substance use/abuse, residents by household, having social security...
