  1. Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage

    PubMed Central

    Norheim, Ole Frithjof

    2015-01-01

    This article discusses what ethicists have called "unacceptable trade-offs" in health policy choices related to universal health coverage (UHC). Since the fiscal space is constrained, trade-offs need to be made. But some trade-offs are unacceptable on the path to universal coverage. Unacceptable choices include, among other examples from low-income countries, to expand coverage for services with lower priority such as coronary bypass surgery before securing universal coverage for high-priority services such as skilled birth attendance and services for easily preventable or treatable fatal childhood diseases. Services of the latter kind include oral rehydration therapy for children with diarrhea and antibiotics for children with pneumonia. The article explains why such trade-offs are unfair and unacceptable even if political considerations may push in the opposite direction.

    The health risks associated with ozone depletion will principally be those due to increased ultraviolet B (UV-B) radiation in the environment, i.e., increased damage to the eyes, the immune system, and the skin. Some new risks may also be introduced with the increased use of alternatives to the ozone-depleting substances (ODSs). Quantitative risk estimates are available for some of the UV-B-associated effects, e.g., cataract and skin cancer; however, the data are insufficient to develop similar estimates for effects such as immunosuppression and the toxicity of alternatives. Ocular damage from UV exposures includes effects on the cornea, lens, iris, and associated epithelial and conjunctival tissues. The most common acute ocular effect of environmental ultraviolet radiation (UVR) is photokeratitis. Also known as snowblindness in skiers, this condition also occurs in other outdoor recreationists. Chronic eye conditions likely to increase with ozone depletion include cataract, squamous cell carcinoma, ocular melanoma, and a variety of corneal/conjunctival effects, e.g., pterygium and pinguecula. Suppression of local (at the site of UV exposure) and systemic (at a distant, unexposed site) immune responses to a variety of antigens has been demonstrated in both humans and animals exposed to UV-B. In experiments with animals these effects have been shown to worsen the course/outcome of some infectious diseases and cancers. There is reasonably good evidence that such immunosuppression plays a role in human carcinogenesis; however, the implications of such immunosuppression for human infectious diseases are still unknown. In light-skinned populations, exposure to solar UVR appears to be the most important environmental risk factor for basal and squamous cell carcinomas and cutaneous melanoma. Originally it was believed that total accumulated exposure to UVR was the most important environmental factor in determining risk for these tumors. Recent information now suggests that only squamous cell carcinoma risk is related to total exposure. In the cases of both basal cell carcinoma and melanoma, new information suggests that increases in risk are tied to early exposures (before about age 15), particularly those leading to severe sunburns. Testing of a number of the chlorofluorocarbon (CFC) alternatives indicates that most of these chemicals have low acute toxicity, and low to moderate chronic toxicity. Some chemicals that were originally proposed as alternatives have been dropped from consideration because these tests raised concerns about toxicity and/or manufacturing difficulties. In one instance, high accidental occupational exposure was associated with liver damage, underlining the need for care in the use of these substitutes. Recent quantitative risk estimates have been developed for cataract, melanoma, and all skin cancers combined. These estimates indicate that under the Montreal Adjustments, cataract and skin-cancer incidence will peak mid-century at additional incidences of just under 3 per 100,000 and about 7 per 100,000, respectively.

    Lanestosa is a chronically polluted site (derelict mine) where the soil (Lanestosa (LA) soil) exceeds screening values (SVs) of regulatory policies in force (Basque Country; Europe) for Zn, Pb and Cd. A scenario-targeted toxicity assessment was carried out on the basis of a multi-endpoint bioassay approach. Acute and chronic toxicity bioassays were conducted with selected test species (Vibrio fischeri, Dictyostelium discoideum, Lactuca sativa, Raphanus sativus and Eisenia fetida) in combination with chemical analysis of soils and elutriates and with bioaccumulation studies in earthworms. Besides, the toxicity profile was compared with that of the mine runoff (RO) soil and of a fresh artificially polluted soil (LAAPS) resembling LA soil pollutant profile. Extractability studies in LA soil revealed that Pb, Zn and Cd were highly available for exchange and/or release into the environment. Indeed, Pb and Zn were accumulated in earthworms and LA soil resulted to be toxic. Soil respiration, V. fischeri, vegetative and developmental cycles of D. discoideum and survival and juvenile production of E. fetida were severely affected. These results confirmed that LA soil had unacceptable environmental risk and demanded intervention. In contrast, although Pb and Zn concentrations in RO soil revealed also unacceptable risk, both metal extractability and toxicity were much lower than in LA soil. Thus, within the polluted site, the need for intervention varied between areas that posed dissimilar risk. Besides, since LAAPS, with a high exchangeable metal fraction, was the most toxic, ageing under in situ natural conditions seemingly contributed to attenuate LA soil risk. As a whole, combining multi-endpoint bioassays with scenario-targeted analysis (including leaching and ageing) provides reliable risk assessment in soils posing unacceptable environmental risk according to SVs, which is useful to optimise the required intervention measures.

    Adair, J. Kathleen

    This study explored science-specific strategies and materials that might be effective components in a Response to Intervention (RTI) science tutorial model for at-risk, academically unsuccessful students in grades 4 -- 8. Through an iterative Delphi process of responding to three rounds of questionnaires, a nationwide panel of 63 experts in the field of science education identified and came to consensus on 44 effective strategies and six instructional materials and types of equipment for supplemental instruction in science, resulting in a three tier RTI tutorial model. This model provides an initial guide for science educators in applicable practices for each tier of the RTI framework, and was developed to assist administrators, program managers, and science educators in developing effective, systemic RTI instructional programming for science education in grades 4 -- 8, and may provide an additional planning tool in determining evidence-based practices that may lead to achievement for at-risk, academically unsuccessful students in grades 4 -- 8. Future research on specific intervention strategies within science and their effects on science achievement are needed, as well as a further examination to test the efficacy of the model on rates of science achievement for at-risk, academically unsuccessful students.

  6. Brownfields and health risks--air dispersion modeling and health risk assessment at landfill redevelopment sites.

    2006-07-01

    Redevelopment of landfill sites in the New Jersey-New York metropolitan area for recreational (golf courses), commercial, and even residential purposes seems to be gaining acceptance among municipal planners and developers. Landfill gas generation, which includes methane and potentially toxic nonmethane compounds usually continues long after closure of the landfill exercise phase. It is therefore prudent to evaluate potential health risks associated with exposure to gas emissions before redevelopment of the landfill sites as recreational, commercial, and, especially, residential properties. Unacceptably high health risks would call for risk management measures such as limiting the development to commercial/recreational rather than residential uses, stringent gas control mechanisms, interior air filtration, etc. A methodology is presented for applying existing models to estimate residual landfill hazardous compounds emissions and to quantify associated health risks. Besides the toxic gas constituents of landfill emissions, other risk-related issues concerning buried waste, landfill leachate, and explosive gases were qualitatively evaluated. Five contiguously located landfill sites in New Jersey intended for residential and recreational redevelopment were used to exemplify the approach. PMID:16869439

    Maintenance of human health on long-duration exploration missions is a primary challenge to mission designers. Indeed, human health risks are currently the largest risk contributors to the risks of evacuation or loss of the crew on long-duration International Space Station missions. We describe a quantitative assessment of the relative probabilities of occurrence of the individual risks to human safety and efficiency during space flight to augment qualitative assessments used in this field to date. Quantitative probabilistic risk assessments will allow program managers to focus resources on those human health risks most likely to occur with undesirable consequences. Truly quantitative assessments are common, even expected, in the engineering and actuarial spheres, but that capability is just emerging in some arenas of life sciences research, such as identifying and minimize the hazards to astronauts during future space exploration missions. Our expectation is that these results can be used to inform NASA mission design trade studies in the near future with the objective of preventing the higher among the human health risks. We identify and discuss statistical techniques to provide this risk quantification based on relevant sets of astronaut biomedical data from short and long duration space flights as well as relevant analog populations. We outline critical assumptions made in the calculations and discuss the rationale for these. Our efforts to date have focussed on quantifying the probabilities of medical risks that are qualitatively perceived as relatively high risks of radiation sickness, cardiac dysrhythmias, medically significant renal stone formation due to increased calcium mobilization, decompression sickness as a result of EVA (extravehicular activity), and bone fracture due to loss of bone mineral density. We present these quantitative probabilities in order-of-magnitude comparison format so that relative risk can be gauged. We address the effects of conservative and nonconservative assumptions on the probability results. We discuss the methods necessary to assess mission risks once exploration mission scenarios are characterized. Preliminary efforts have produced results that are commensurate with earlier qualitative estimates of risk probabilities in this and other operational contexts, indicating that our approach may be usefully applied in support of the development of human health and performance standards for long-duration space exploration missions. This approach will also enable mission-specific probabilistic risk assessments for space exploration missions.

  10. Health risks in perspective: Judging health risks of energy technologies

    SciTech Connect

    Rowe, M.D.

    1992-09-18

    Almost daily, Americans receive reports from the mass news media about some new and frightening risk to health and welfare. Most such reports emphasize the newsworthiness of the risks -- the possibility of a crisis, disagreements among experts, how things happened, who is responsible for fixing them, how much will it cost, conflict among parties involved, etc. As a rule, the magnitudes of the risks, or the difficulty of estimating those magnitudes, have limited newsworthiness, and so they are not mentioned. Because of this emphasis in the news media, most people outside the risk assessment community must judge the relative significance of the various risks to which we all are exposed with only that information deemed newsworthy by reporters. This information is biased and shows risks in isolation. There is no basis for understanding and comparing the relative importance of risks among themselves, or for comparing one risk, perhaps a new or newly-discovered one, in the field of all risks. The purpose of this report is to provide perspective on the various risks to which we are routinely exposed. It serves as a basis for understanding the meaning of quantitative risk estimates and for comparing new or newly-discovered risks with other, better-understood risks. Specific emphasis is placed on health risks of energy technologies.

  12. Children at health risks.

    PubMed

    Sekar, H R

    1992-01-01

    In India, 69% of the children of the working class die, most of whom are child laborers. Economic pressure forces parents to make their children work. Employers want child workers because they can manipulate them and pay them low wages, thereby ensuring their viability. The caste system induces social inequality, inheritance invokes cultural inequality, and patriarchal socialization is responsible for gender inequality, all of which perpetuates exploitation of children by employers. In Sivakasi, an estimated 125,000 children make up the child labor force, comprising 30% of the entire labor force. 75% are from the lowest castes. 90% of child workers are girls because they are more obedient and accept even lower wages than boys, and girls need to save for their dowry. Girls often suffer verbal and physical abuse. Like their parents who were also child workers, child workers are illiterate and work long hours. A small rich elite in Sivakasi controls most of the trading and industrial capital, educational institutions, and voluntary organizations. Employers' agents give parents a loan and use their children's labor as security. Each day, they bring child workers to Sivakasi in factory buses from villages to work at least 12 hour days. They work under hazardous conditions, e.g., working with toxic chemicals. Coughing, sore throat, dizziness, methemoglobinemia, and anemia are common effects of ingestion or inhalation of chlorate dust. Inhalation of sulphur dust causes respiratory infections, eye infections, and chronic lung diseases (e.g., asthma). Fires and explosions are common risks for working children. Factory management seldom undertake fire prevention measures. An extensive survey of the problem of child labor is needed in Sivakasi before systematic planning to protect children could be done. Overall development, especially agricultural development, is needed. Parents, employers, enforcement authorities, trade unions, and social groups need to be sensitized to the abomination of child labor. The government should provide monetary incentives to employers that do not use child labor and disincentives to those that do. PMID:12318359

    Current marijuana use rates are the highest they have been in the past decade and are not likely to decrease given the legalization of marijuana for medicinal and recreational use. Concurrently, the nation is facing epidemic levels of obesity, cardiovascular disease, and diabetes mellitus; but, little is known about the intersecting relationships of marijuana use and cardiometabolic health. The objective of this study was to explore emerging issues in context with the intersection of cardiometabolic risk and marijuana use. This topic has potential important implications for our nation's health as we relax our approach to marijuana but continue to have unacceptable rates of cardiometabolic illnesses. PMID:24471513

    The risk assessment matrix is a widely accepted, semi-quantitative tool for assessing risks, and setting priorities in risk management. Although the method can be useful to promote discussion to distinguish high risks from low risks, a published critique described a problem when the frequency and severity of risks are negatively correlated. A theoretical analysis showed that risk predictions could be misleading. We evaluated a practical public health example because it provided experiential risk data that allowed us to assess the practical implications of the published concern that risk matrices would make predictions that are worse than random. We explored this predicted problem by constructing a risk assessment matrix using a public health risk scenario—Tainted blood transfusion infection risk—That provides negative correlation between harm frequency and severity. We estimated the risk from the experiential data and compared these estimates with those provided by the risk assessment matrix. Although we validated the theoretical concern, for these authentic experiential data, the practical scope of the problem was limited. The risk matrix has been widely used in risk assessment. This method should not be abandoned wholesale, but users must address the source of the problem, apply the risk matrix with a full understanding of this problem and use matrix predictions to inform, but not drive decision-making.

    1982-01-01

    The increasing use of normal donors for leukapheresis to provide granulocyte concentrates requires careful monitoring of recruitment and operational procedures to minimize donor health risks. Of 18,288 leuka- and leukaplateletphereses performed in American Red Cross regional blood services during a 12-month period, only 0.27% were discontinued because of acute donor reactions. None of these reactions had serious or long-term consequences for the donors. The potential toxicities of corticosteroids and hydroxyethyl starch, and the theoretical hazards of lymphocyte depletion, raise unanswerable questions concerning long-term safety, although no serious adverse reactions related to these factors have been observed. Critical factors for leukapheresis donor safety are: selective donor recruitment, adherence to operational protocols, and continuous and informed interest of physicians responsible for pheresis programs. Additional data are needed to assess the effects of repeated leukapheresis on donors and to establish rational guidelines for donor recruitment. PMID:6180961

    This review provides a basis for substantiating both kinetically and pathologically the differences between chrysotile and amphibole asbestos. Chrysotile, which is rapidly attacked by the acid environment of the macrophage, falls apart in the lung into short fibers and particles, while the amphibole asbestos persist creating a response to the fibrous structure of this mineral. Inhalation toxicity studies of chrysotile at non-lung overload conditions demonstrate that the long (>20?µm) fibers are rapidly cleared from the lung, are not translocated to the pleural cavity and do not initiate fibrogenic response. In contrast, long amphibole asbestos fibers persist, are quickly (within 7?d) translocated to the pleural cavity and result in interstitial fibrosis and pleural inflammation. Quantitative reviews of epidemiological studies of mineral fibers have determined the potency of chrysotile and amphibole asbestos for causing lung cancer and mesothelioma in relation to fiber type and have also differentiated between these two minerals. These studies have been reviewed in light of the frequent use of amphibole asbestos. As with other respirable particulates, there is evidence that heavy and prolonged exposure to chrysotile can produce lung cancer. The importance of the present and other similar reviews is that the studies they report show that low exposures to chrysotile do not present a detectable risk to health. Since total dose over time decides the likelihood of disease occurrence and progression, they also suggest that the risk of an adverse outcome may be low with even high exposures experienced over a short duration.

    2014-01-01

    Objective: To describe contemporary air dispersion modeling and health risk assessment methodologies applied to alumina refineries and to summarize recent results. Methods: Air dispersion models using emission source and meteorological data have been used to assess ground-level concentrations (GLCs) of refinery emissions. Short-term (1-hour and 24-hour average) GLCs and annual average GLCs have been used to assess acute health, chronic health, and incremental carcinogenic risks. Results: The acute hazard index can exceed 1 close to refineries, but it is typically less than 1 at neighboring residential locations. The chronic hazard index is typically substantially less than 1. The incremental carcinogenic risk is typically less than 10?6. Conclusions: The risks of acute health effects are adequately controlled, and the risks of chronic health effects and incremental carcinogenic risks are negligible around referenced alumina refineries.

    Objective Risk communication and management are essential to the ethical conduct of research, yet addressing risks may be time consuming for investigators and institutional review boards (IRBs) may reject study designs that appear too risky. This can discourage needed research, particularly in higher risk protocols or those enrolling potentially vulnerable individuals, such as those with some level of suicidality. Improved mechanisms for addressing research risks may facilitate much needed psychiatric research. This article provides mental health researchers with practical approaches to: 1) identify and define various intrinsic research risks; 2) communicate these risks to others (e.g., potential participants, regulatory bodies, society); 3) manage these risks during the course of a study; and 4) justify the risks. Methods As part of a National Institute of Mental Health (NIMH)-funded scientific meeting series, a public conference and a closed-session expert panel meeting were held on managing and disclosing risks in mental health clinical trials. The expert panel reviewed the literature with a focus on empirical studies and developed recommendations for best practices and further research on managing and disclosing risks in mental health clinical trials. IRB review was not required because there were no human subjects. The NIMH played no role in developing or reviewing the manuscript. Results Challenges, current data, practical strategies, and topics for future research are addressed for each of four key areas pertaining to management and disclosure of risks in clinical trials: identifying and defining risks, communicating risks, managing risks during studies, and justifying research risks. Conclusions Empirical data on risk communication, managing risks, and the benefits of research can support the ethical conduct of mental health research and may help investigators better conceptualize and confront risks and to gain IRB approval.

    Aflatoxins are secondary metabolites produced by a group of strains, mainly Aspergillus and Penicillium species. These mycotoxins are bifurano-coumarin derivatives group with four major products B1, B2, G1 and G2 according to blue or green fluorescence emitted in ultraviolet light and according to chromatographic separation. After metabolism of aflatoxin B1 and B2 in the mammalian body, result two metabolites M1 and M2 as hydroxylated derivatives of the parent compound. Aflatoxins have high carcinogenic potential, the most powerful carcinogens in different species of animals and humans. International Agency for Research on Cancer has classified aflatoxin B1 in Group I carcinogens. The target organ for aflatoxins is the liver. In chronic poisoning, aflatoxin is a risk to health, for a long term causing cancer (hepatocellular carcinoma), and in acute intoxications aflatoxin is lethal.

Risk levels were measured by odds ratio, controlling for: health status, sex, social support and stressful life events. Results show that those at risk are blue collar workers and less qualified workers of traditional sectors. Lower job latitude could explain those results. Results show that risk of mental health problems is significantly higher in the following industrial sectors: leather, chemicals, paint and varnish industries; urban bus transport and taxi; shoe, clothing and textile retail stores; department stores; restaurant services; insurance and public administration (excluding defence). Risk of mental health problems is higher in the following professions road transport (excluding truck drivers); textile, leather, fur manufacturing and repairing; housekeeping and maintenance; painters, tapestry-workers, insulation and waterproofing, food and beverages sector; data processors; editors and university professors.

    The health risks facing workers involved in decommissioning nuclear facilities are a critical concern as the nuclear weapons complex and nuclear power plants begin to be dismantled. In addition to risks from exposure to radioactive materials, there are risks from other common industrial materials like crystalline silica dust and asbestos. We discuss these issues in the context of recent research on the risk of low-level ionizing radiation, the classification of crystalline silica as a carcinogen, and early experience with decommissioning nuclear facilities in the United States. Health and safety advocates will need to be vigilant to prevent worker exposure. PMID:17208791

    Environmental and occupational health effects associated with exposures to various chemicals are a subject of increasing concern. One recently developed methodology for assessing the health impacts of various chemical compounds involves the classification of similar chemicals into risk-assessment categories (RACs). This report reviews documented human health effects for a broad range of pollutants, classified by RACs. It complements other studies that have estimated human health effects by RAC based on analysis and extrapolation of data from animal research.

  12. Health and environmental risks of energy systems

    SciTech Connect

    Hamilton, L.D.

    1984-01-01

    This paper gives four examples of health risk assessments of energy systems: (1) Comparative risk assessment of the health effects of the coal and nuclear fuel cycles. Estimates differ from previous values chiefly by inclusion of ranges of uncertainty, but some coal-cycle numbers were re-estimated. Upper-boundary public disease risks of air pollution from coal-fired plants dominate. Reactors probably account for most of the potential effect of major nuclear accidents. Accidental death rates in electricity generation are low for reactors and higher for coal. (2) Upper boundary air pollution health risks of existing fossil-based energy technologies in the United States. Preliminary mortality estimates were obtained combining potential impacts of three index pollutants - SO/sub 4/, NO/sub 2/, and CO - as independent measures of risk. Four fuel cycle trajectories leading to three end-uses were analyzed. Example results: domestic wood burning has substantial potential impact, with an upper boundary exceeding that of coal; upper-boundary air pollution impacts of gas can exceed those of oil, because of NO/sub 2/. (3) Health risks of acid deposition and other transported air pollutants, carried out as part of an assessment of the US Congress Office of Technology Assessment (OTA) Acid Rain and Transported Air Pollutants - Implications for Public Policy. Three scenarios were examined, leading to estimates of 40,000 to 50,000 annual premature deaths, depending on year (1978 vs 2000) and scenario (holding total emissions constant vs 30% reduction). (4) health effects of uranium mill tailings piles. Mortality risk is estimated to be minuscule (8.7 x 10/sup -9/ average individual lifetime cancer risk from a model mill, compared with 9.5 x 10/sup -4/ for background radiation). Methods that sum risks over the indefinite future are shown to be to be unrealistic. 39 references, 7 figures, 15 tables.

    Background. Individuals who make a living through agriculture and animal husbandry are faced with a variety of physical and psychological health risks. In many international studies, it has been shown that these risks can result in disease. The purpose of this study is to summarize the health risks faced by Turkish agricultural workers. Materials and Methods. This study used a nonrandom, convenience sample. The biopsychosocial health statuses of 177 farmers from 11 central villages in Kars, Turkey, were examined. Results. It was determined that the depression rate among the study group was 62.1%, the rate of physical health problems was 52.0%, and the rate of social isolation was 53.7%. There was a statistically significant difference between the depression scale scores and lower education levels, having ? three children, and physical health problems, as well as the physical condition of the farmers' homes. There was a significant difference between poor physical health and older age, lower education levels, having ? three children, and social isolation. Conclusions. In providing data-based evidence, it is believed that this study will contribute considerably to understanding the causality of health problems in this population and in planning the development of public health and veterinary services based on regional needs.

    The radiation environment in space poses significant challenges to human health and is a major concern for long duration manned space missions. Outside the Earth's protective magnetosphere, astronauts are exposed to higher levels of galactic cosmic rays, whose physical characteristics are distinct from terrestrial sources of radiation such as x-rays and gamma-rays. Galactic cosmic rays consist of high energy and high mass nuclei as well as high energy protons; they impart unique biological damage as they traverse through tissue with impacts on human health that are largely unknown. The major health issues of concern are the risks of radiation carcinogenesis, acute and late decrements to the central nervous system, degenerative tissue effects such as cardiovascular disease, as well as possible acute radiation syndromes due to an unshielded exposure to a large solar particle event. The NASA Human Research Program's Space Radiation Program Element is focused on characterization and mitigation of these space radiation health risks along with understanding these risks in context of the other biological stressors found in the space environment. In this overview, we will provide a description of these health risks and the Element's research strategies to understand and mitigate these risks.

    1992-09-01

    The purpose of this report is to provide perspective on the various risks to which man is routinely exposed. It serves as a basis for understanding the meaning of quantitative risk estimates and for comparing new or newly-discovered risks with other, better-understood risks. Specific emphasis is placed on health risks of energy technologies. This report is not a risk assessment; nor does it contain instructions on how to do a risk assessment. Rather, it provides background information on how most of us think about risks and why it is difficult to do it rationally, it provides a philosophy and data with which to do a better job of judging risks more rationally, and it provides an overview of where risks of energy technologies fit within the spectrum of all risks. Much of the quantitative information provided here is on relative risk of dying of various causes. This is not because risk of dying is seen as the most important kind of risk, but because the statistics on mortality rates by cause are the highest quality data available on health risks in the general population.

    This article presents the results of a comparative environmental risk-ranking exercise that was conducted in the United Arab Emirates (UAE) to inform a strategic planning process led by the Environment Agency-Abu Dhabi (EAD). It represents the first national-level application of a deliberative method for comparative risk ranking first published in this journal. The deliberative method involves a five-stage process that includes quantitative risk assessment by experts and deliberations by groups of stakeholders. The project reported in this article considered 14 categories of environmental risks to health identified through discussions with EAD staff: ambient and indoor air pollution; drinking water contamination; coastal water pollution; soil and groundwater contamination; contamination of fruits, vegetables, and seafood; ambient noise; stratospheric ozone depletion; electromagnetic fields from power lines; health impacts from climate change; and exposure to hazardous substances in industrial, construction, and agricultural work environments. Results from workshops involving 73 stakeholders who met in five separate groups to rank these risks individually and collaboratively indicated strong consensus that outdoor and indoor air pollution are the highest priorities in the UAE. Each of the five groups rated these as being among the highest risks. All groups rated soil and groundwater contamination as being among the lowest risks. In surveys administered after the ranking exercises, participants indicated that the results of the process represented their concerns and approved of using the ranking results to inform policy decisions. The results ultimately shaped a strategic plan that is now being implemented. PMID:20723144

    The paper describes the security concerns related to Electronic Health Records (EHR) both in registration of data and integration of systems. A description of the current state of EHR systems in Iceland is provided, along with the Ministry of Health's future vision and plans. New legislation provides the opportunity for increased integration of EHRs and further collaboration between institutions. Integration of systems, along with greater availability and access to EHR data, requires increased security awareness since additional risks are introduced. The paper describes the core principles of information security as it applies to EHR systems and data. The concepts of confidentiality, integrity, availability, accountability and traceability are introduced and described. The paper discusses the legal requirements and importance of performing risk assessment for EHR data. Risk assessment methodology according to the ISO/IEC 27001 information security standard is described with examples on how it is applied to EHR systems. PMID:20543313

    2014-01-01

    PURPOSE To describe the frequency and patient-reported readiness to change, desire to discuss, and perceived importance of 13 health risk factors in a diverse range of primary care practices. METHODS Patients (n = 1,707) in 9 primary care practices in the My Own Health Report (MOHR) trial reported general, behavioral, and psychosocial risk factors (body mass index [BMI], health status, diet, physical activity, sleep, drug use, stress, anxiety or worry, and depression). We classified responses as “at risk” or “healthy” for each factor, and patients indicated their readiness to change and/or desire to discuss identified risk factors with providers. Patients also selected 1 of the factors they were ready to change as most important. We then calculated frequencies within and across these factors and examined variation by patient characteristics and across practices. RESULTS On average, patients had 5.8 (SD = 2.12; range, 0–13) unhealthy behaviors and mental health risk factors. About 55% of patients had more than 6 risk factors. On average, patients wanted to change 1.2 and discuss 0.7 risks. The most common risks were inadequate fruit/vegetable consumption (84.5%) and overweight/obesity (79.6%). Patients were most ready to change BMI (33.3%) and depression (30.7%), and most wanted to discuss depression (41.9%) and anxiety or worry (35.2%). Overall, patients rated health status as most important. CONCLUSIONS Implementing routine comprehensive health risk assessments in primary care will likely identify a high number of behavioral and psychosocial health risks. By soliciting patient priorities, providers and patients can better manage counseling and behavior change. PMID:25384812

  5. Risk Analysis for Environmental Health Triage

    SciTech Connect

    Bogen, K T

    2005-11-18

    The Homeland Security Act mandates development of a national, risk-based system to support planning for, response to and recovery from emergency situations involving large-scale toxic exposures. To prepare for and manage consequences effectively, planners and responders need not only to identify zones of potentially elevated individual risk, but also to predict expected casualties. Emergency response support systems now define ''consequences'' by mapping areas in which toxic chemical concentrations do or may exceed Acute Exposure Guideline Levels (AEGLs) or similar guidelines. However, because AEGLs do not estimate expected risks, current unqualified claims that such maps support consequence management are misleading. Intentionally protective, AEGLs incorporate various safety/uncertainty factors depending on scope and quality of chemical-specific toxicity data. Some of these factors are irrelevant, and others need to be modified, whenever resource constraints or exposure-scenario complexities require responders to make critical trade-off (triage) decisions in order to minimize expected casualties. AEGL-exceedance zones cannot consistently be aggregated, compared, or used to calculate expected casualties, and so may seriously misguide emergency response triage decisions. Methods and tools well established and readily available to support environmental health protection are not yet developed for chemically related environmental health triage. Effective triage decisions involving chemical risks require a new assessment approach that focuses on best estimates of likely casualties, rather than on upper plausible bounds of individual risk. If risk-based consequence management is to become a reality, federal agencies tasked with supporting emergency response must actively coordinate to foster new methods that can support effective environmental health triage.

    This study investigates the potential health risk from urban gardening. The concentrations of the trace elements arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in five common garden crops from three garden sites in Copenhagen were measured. Concentrations (mg/kg dw) of As were 0.002-0.21, Cd 0.03-0.25, Cr < 0.09-0.38, Cu 1.8-8.7, Ni < 0.23-0.62, Pb 0.05-1.56, and Zn 10-86. Generally, elemental concentrations in the crops do not reflect soil concentrations, nor exceed legal standards for Cd and Pb in food. Hazard quotients (HQs) were calculated from soil ingestion, vegetable consumption, measured trace element concentrations and tolerable intake levels. The HQs for As, Cd, Cr, Cu, Ni, and Zn do not indicate a health risk through urban gardening in Copenhagen. Exposure to Pb contaminated sites may lead to unacceptable risk not caused by vegetable consumption but by unintentional soil ingestion. PMID:25796073

    Development efforts since the late 1970s have resulted in a generalized method for ranking health hazards. This method provides the basis for a wide range of applications where decisions are needed for allocating resources on the basis of health risk considerations. It has been used for more than a decade to solve real problems, and it is supported by 23 publications in the open literature. The diversity of this generalized methodology allows us to provide support in a great number of problem areas. we give four examples in this manuscript: the relative toxicities of petroleum mixtures; a method to derive Emergency Response Planning Guides; an estimate of the possible carcinogenic potency of tungsten, an alternative material to depleted uranium for heavy armor penetrators; and an approach to low dose extrapolation. Our experience suggests that many more applications of the original concept and variations on it can be of utility in military situations. Some potentially fruitful areas may be in the: development of a health-risk-ranking system for alternative solutions to manufacturing, waste management, and remediation; provision of a basis for identifying levels of hazardous agents which are below health concerns, or which should be of concern; development of a framework for evaluating chemicals and radioactive materials on the same basis, and in the development of a battery of in vitro bioassays which could take the place of long-term whole animal tests.

  13. Reliability, resilience and vulnerability criteria for the evaluation of time-dependent health risks: A hypothetical case study of wellhead protection

    A hypothetical case study of groundwater contaminant protection was carried out using time-dependent health risk calculations. The case study focuses on a hypothetical zoning project for parcels of land around a well field in northern Indiana, where the control of cancer risk relative to a mandated cancer risk threshold is of concern in the management strategy. Within our analysis, we include both uncertainty in the subsurface transport and variability in population behavior in the calculation of time-dependent health risks. From these results we introduce risk maps, a visual representation of the probability of an unacceptable health risk as a function of population behavior and the time at which exposure to the contaminant begins. We also evaluate the time-dependent risks with three criteria from water resource literature: reliability, resilience, and vulnerability (RRV). With respect to health risk from a groundwater well, the three criteria determine: the probability that a well produces safe water (reliability), the probability that a contaminated well returns to an uncontaminated state within a specified time interval (resilience), and the overall severity in terms of health impact of the contamination at a well head (vulnerability). The results demonstrate that the distributions of RRV values for each parcel of land are linked to the time-dependent concentration profile of the contaminant at the well, and the toxicological characteristics of the contaminant. The proposed time-dependent risk calculation expands on current techniques to include a continuous exposure start time, capable of reproducing the maximum risk while providing information on the severity and duration of health risks. Overall this study suggests that, especially in light of the inherent complexity of health-groundwater systems, RRV are viable criteria for relatively simple and effective evaluation of time-dependent health risk. It is argued that the RRV approach, as applied to consideration of potential health impact, allows for more informed, health-based decisions regarding zoning for wellhead protection.

    OBJECTIVE Research has suggested that a higher risk of type 2 diabetes associated with sleep characteristics exists. However, studies have not thoroughly assessed the potential confounding effects of mental health conditions associated with alterations in sleep. RESEARCH DESIGN AND METHODS We prospectively assessed the association between sleep characteristics and self-reported incident diabetes among Millennium Cohort Study participants prospectively followed over a 6-year time period. Surveys are administered approximately every 3 years and collect self-reported data on demographics, height, weight, lifestyle, features of military service, sleep, clinician-diagnosed diabetes, and mental health conditions assessed by the PRIME-MD Patient Health Questionnaire and the PTSD Checklist–Civilian Version. Statistical methods for longitudinal data were used for data analysis. RESULTS We studied 47,093 participants (mean 34.9 years of age; mean BMI 26.0 kg/m2; 25.6% female). During 6 years of follow-up, 871 incident diabetes cases occurred (annual incidence 3.6/1,000 person-years). In univariate analyses, incident diabetes was significantly more likely among participants with self-reported trouble sleeping, sleep duration <6 h, and sleep apnea. Participants reporting incident diabetes were also significantly older, of nonwhite race, of higher BMI, less likely to have been deployed, and more likely to have reported baseline symptoms of panic, anxiety, posttraumatic stress disorder, and depression. After adjusting for covariates, trouble sleeping (odds ratio 1.21 [95% CI 1.03–1.42]) and sleep apnea (1.78 [1.39–2.28]) were significantly and independently related to incident diabetes. CONCLUSIONS Trouble sleeping and sleep apnea predict diabetes risk independent of mental health conditions and other diabetes risk factors. PMID:23835691

    e-Health, as an inter-jurisdictional enterprise, presents risks to patient health data that involve not only technology and professional protocols but also laws, regulations and professional security cultures. The USA Patriot Act is one example of how national laws can shape these concerns. Secure e-Health therefore requires not only national standardization of professional education and protocols but also global interoperability of regulations and laws. Some progress in this regard has been made in the European context; however, even here developments are incomplete, and nothing similar has been accomplished on a global scale. Professional health information organizations must take the lead in developing appropriate high-level principles for professional certification and security protocols and in harmonizing these on a global basis, so that they can provide a firm and consistent foundation for international treaties. Such developments should occur in concert with other health professions, so that coordinated requirements are integrated into revisions of the relevant codes of ethics. This presentation identifies and addresses some of the ethical and legal issues and proposes a series of recommendations. PMID:17084665

  16. A tiered assessment framework to evaluate human health risk of contaminated sediment.

    Greenfield, Ben K; Melwani, Aroon R; Bay, Steven M

    2015-07-01

    For sediment contaminated with bioaccumulative pollutants (e.g., PCBs and organochorine pesticides), human consumption of seafood that contain bioaccumulated sediment-derived contaminants is a well-established exposure pathway. Historically, regulation and management of this bioaccumulation pathway has focused on site-specific risk assessment. The state of California (United States) is supporting the development of a consistent and quantitative sediment assessment framework to aid in interpreting a narrative objective to protect human health. The conceptual basis of this framework focuses on 2 key questions: 1) do observed pollutant concentrations in seafood from a given site pose unacceptable health risks to human consumers? and 2) is sediment contamination at a site a significant contributor to seafood contamination? The first question is evaluated by interpreting seafood tissue concentrations at the site, based on health risk calculations. The second question is evaluated by interpreting site-specific sediment chemistry data using a food web bioaccumulation model. The assessment framework includes 3 tiers (screening assessment, site assessment, and refined site assessment), which enables the assessment to match variations in data availability, site complexity, and study objectives. The second and third tiers use a stochastic simulation approach, incorporating information on variability and uncertainty of key parameters, such as seafood contaminant concentration and consumption rate by humans. The framework incorporates site-specific values for sensitive parameters and statewide values for difficult to obtain or less sensitive parameters. The proposed approach advances risk assessment policy by incorporating local data into a consistent region-wide problem formulation, applying best available science in a streamlined fashion.

  17. Behavioral science perspectives on health hazard/health risk appraisal.

    PubMed Central

    Becker, M H; Janz, N K

    1987-01-01

    Health-promotion efforts often employ HRA as a device for providing an individual with quantitative information about the consequences of personal health-related behaviors and as an attempt to motivate the client to adopt recommendations directed at establishing a healthier lifestyle. From a behavioral science perspective, the HRA approach and process contain elements that (at least in retrospective analysis) appear to be founded in relevant bodies of theory. First, HRA seems to be a reasonably efficient mechanism for transmitting information relative to associations between personal health behaviors and mortality risks. Moreover, while general knowledge and advice about the untoward consequences of risk factors (such as smoking, obesity, high blood pressure, etc.) are currently widespread, HRA provides new and specific information: the client's own relative risks. Some individuals who voluntarily participate in HRA bring to the experience an already high level of readiness to take action; for them, the technique may constitute the final necessary stimulus or "cue to action" [12]. Referring to a "borrowing from the future" phenomenon, Green points out that "some educational efforts are really only triggers to behavior that would have changed eventually anyway" [44, p. 159]. Thus, where motivation is sufficiently high, receipt of HRA feedback information may by itself be capable of inducing behavior change. Second, the focus on awareness and personalization of mortality risk fits well with most theoretical formulations concerning attitudes and beliefs involved in health-related decision making. Although the emphasis on mortality and often distant negative outcomes is problematic, increasing the client's perception of personal vulnerability is a psychologically defensible approach, and fear arousal can generate attitude change (although questions of appropriate level, duration of effects obtained, acceptability, etc. still need to be resolved). Third, HRA might be expected to enhance the client's perception of the benefits associated with lifestyle modifications and may even increase personal belief in his or her ability to undertake such changes in behavior. However, in light of the fact that the behaviors to be altered are complex, usually well-established and repetitive, and require different skills to extinguish, the provision of typical HRA feedback should not (on a theoretical basis) ordinarily be expected to accomplish much beyond information transmission, belief or attitude change, and the induction of some level of motivation.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:3679842

    Health risk behaviors among students attending 4-year colleges in California were examined. The Youth Risk Behavior Survey for College Students was administered in a two-stage (29 universities, 5,652 students) random sample. All campuses and 3,810 (69%) students participated in the survey. In the 30 days preceding the survey, 36.7% of the students had binged at least once while drinking; 25.3% had driven after consuming alcohol; 32% had ridden in a car with someone who had been drinking; 17.6% had used marijuana; and 6% had carried a knife, gun, or club. More than half of the students who were sexually active and not married or living with a primary partner had not used a condom the last time they had sexual intercourse. Only 5% of regular bicycle riders always wore a helmet. Fewer than half (44%) reported aerobic physical activity on 3 or more of the preceding 7 days. The results of this study indicate a substantial amount of serious, risky health behaviors among California college students. PMID:9164056

    Impaired brain health encompasses a range of clinical outcomes, including stroke, dementia, vascular cognitive impairment, cognitive ageing, and vascular functional impairment. Conditions associated with poor brain health represent leading causes of global morbidity and mortality, with projected increases in public health burden as the population ages. Many vascular risk factors are shared predictors for poor brain health. Moreover, subclinical brain MRI markers of vascular damage are risk factors shared between stroke and dementia, and can be used for risk stratification and early intervention. The broad concept of brain health has resulted in a conceptual shift from vascular risk factors to determinants of brain health. Global campaigns to reduce cardiovascular diseases by targeting modifiable risk factors are necessary and will have a broad impact on brain health. Research is needed on the distinct and overlapping aetiologies of brain health conditions, and to define MRI markers to help clinicians identify patients who will benefit from aggressive prevention measures.

    2004-02-01

    Polychlorinated biphenyls (PCB) were manufactured between 1929 and 1989. Due to their great chemical persistence, these substances have been used for many different purposes. These chemical properties, however, caused PCB to accumulate in the food chain and resulted in background exposure of the general population. PCB has also been used as plasticizer for sealants in prefabricated buildings, thus causing problems to the present date. At the end of the 90-ties in a school in Nuremberg, Germany, elevated PCB concentrations were measured in indoor air. Some of these results were higher than 3,000 ng/m(3) which means decontamination according to the German "PCB directive". Press coverage made these results a matter of public debate, so that teachers, school children and parents were highly worried because of possible health effects. The Bavarian Minister for Health, Nutrition and Consumer Protection asked us to examine school children and teachers with regard to their internal PCB exposure and health complaints. A group of school children from a non-contaminated school served as controls. For the determination of PCB levels the plasma samples were blinded before analysis. Lower chlorinated PCB (PCB 28, 52, 101) were detected more often and in higher concentrations in plasma samples of school children of the contaminated school compared to the controls. The plasma levels of the higher chlorinated PCBs (PCB 138, 153, 180) did not show similar differences between exposed and non-exposed school children. The relative PCB doses additionally taken up in the contaminated school were less then 5 % of the background exposure of the children. That is why it could finally be concluded that no appreciable additional health risk may result from inhalation of PCB contaminated indoor air in this school. Due to the design, performance and interpretation of this study, including representatives of parents and teachers, these results were widely accepted by most of the parents who initially had been very concerned about possible health effects.

Mass populations of toxin-producing cyanobacteria in natural and controlled waterbodies include blooms and scums of planktonic species, and mats and biofilms of benthic species. Toxic cyanobacterial populations have been reported in freshwaters in over 45 countries, and in numerous brackish, coastal, and marine environments. The principal toxigenic genera are listed. Known sources of the families of cyanobacterial toxins (hepato-, neuro-, and cytotoxins, irritants, and gastrointestinal toxins) are briefly discussed. Key procedures in the risk management of cyanobacterial toxins and cells are reviewed, including derivations (where sufficient data are available) of tolerable daily intakes (TDIs) and guideline values (GVs) with reference to the toxins in drinking water, and guideline levels for toxigenic cyanobacteria in bathing waters. Uncertainties and some gaps in knowledge are also discussed, including the importance of exposure media (animal and plant foods), in addition to potable and recreational waters. Finally, we present an outline of steps to develop and implement risk management strategies for cyanobacterial cells and toxins in waterbodies, with recent applications and the integration of Hazard Assessment Critical Control Point (HACCP) principles.

    Risk assessment, a major activity of both health and regulatory agencies, is subject to large and unavoidable uncertainties. Thus, different teams of knowledgeable experts can come to different conclusions about risks to human health from various sorts of hazards. This report examines and compares analyses by two or more agencies of ten health hazards or potential hazards: ethylene dibromide, formaldehyde, Tris, dioxin (limited to cancer risks of contaminated soil), lead (reproductive effects), cotton dust, noise (long-term hearing impairment), passive smoking, dietary fat (cancer risks), and the radiation hazards of mammography. Each set of risk assessments is analyzed in depth. The report then turns to cross-cutting analyses of such matters as setting priorities for risk assessment, approaches and methods used to evaluate different kinds of risks, and the relationships between risk assessment and risk management. Overall, the report found large differences among risk assessments of the same hazard, but these differences are often quite appropriate.

    In this study, the health risk of toxic volatile organic compounds (VOCs) species for well drillers, working at an exposure site around a well of underground coal fire site, was presented in a case of Shanxi province. The samples were collected by Teflon sampling bags and measured by gas chromatography-mass spectrometry (GC-MS). The results showed that isopropyl alcohol was the most abundant compound of VOCs, with the geometric mean concentrations of 1700.38 ?g/m(3). The geometric mean concentrations of individual BTEX compounds obtained in all of the sampling campaign were 131.64, 10.15, 15.53, and 25.38 ?g/m(3) for benzene, toluene, ethyl-benzene, and xylenes, respectively. Relative proportion of BTEX averaged as 8.5:0.7:1:1.6. High B/T ratio (13.0) and low T/E ratio (0.7) was observed in this study. For non-cancer risk in this study, the hazardous quotient (HQ) of 1,2-dibromoethane, 1,3-butadiene, and benzene was 17.91, 1.71, and 43.88, respectively, mean their non-cancer risk was at the level of definite concern. The HQ sum of 20 VOCs was 64.94, much higher than 1. The cancer risk values of benzene (7.01E-04), 1,2-dibromoethane (1.91E-04), carbon tetrachloride (1.55E-04), and 1,3-butadiene (1.09E-04) were greater than 10(-4), indicating that they were all definite risk. The total cancer risk of all VOCs species was 1.39E-03, almost 14 times more than the level of definite risk. The stochastic exposure assessment of all VOCs species total cancer risk using the Monte Carlo simulation analysis shows that 5 and 95 % cancer risks were predicted to be 7.60E-04 and 2.75E-03, respectively. The cancer risk for all VOCs species is unacceptable. The results of sensitivity analysis show that benzene, carbon tetrachloride, and 1,3-butadiene exposure account for more than 98 % contributions to the estimated risk for drillers, indicating that those VOCs species exposure has greater impact than other species on risk assessment. Both combined effects and independent effects of each VOCs species have to be considered. PMID:26004562

    Abstract This study evaluated the impact of The Prevention Plan™ on employee health risks after 1 year of integrated primary prevention (wellness and health promotion) and secondary prevention (biometric and lab screening as well as early detection) interventions. The Prevention Plan is an innovative prevention benefit that provides members with the high-tech/high-touch support and encouragement they need to adopt healthy behaviors. Support services include 24/7 nurse hotlines, one-on-one health coaching, contests, group events, and employer incentives. Specifically, we analyzed changes in 15 health risk measures among a cohort of 2606 employees from multiple employer groups who completed a baseline health risk appraisal, blood tests, and biometric screening in 2008 and who were reassessed in 2009. We then compared the data to the Edington Natural Flow of risks. The cohort showed significant reduction in 10 of the health risks measured (9 at P???0.01 and 1 at P???0.05). The most noticeable changes in health risks were a reduction in the proportion of employees with high-risk blood pressure (42.78%), high-risk fasting blood sugar (31.13%), and high-risk stress (24.94%). There was an overall health risk transition among the cohort with net movement from higher risk levels to lower risk levels (P?risk category, a decrease of 3.61% in the moderate-risk category, and a 5.79% decrease in the high-risk category. Compared to Edington's Natural Flow model, 48.70% of individuals in the high-risk category moved from high risk to moderate risk (Natural Flow 31%), 46.35% moved from moderate risk to low risk (Natural Flow 35%), 15.65% moved from high risk to low risk (Natural Flow 6%), and 87.33% remained in the low-risk category (Natural Flow 70%) (P?Health Management 2010;13:275–284) PMID:20879909

    The socioeconomic and sanitary conditions in many countries make it necessary to weigh as precisely as possible the uncertainties which might affect the health of internationally adopted children, which is one of the key drivers to adoption decision. Indeed, health troubles are more and more frequent among children proposed by countries, at a time when there are fewer children to be adopted. Hence the institutions and the actors in the field of international adoption are compelled to frequently update their professional practices, so as to cope both with the declining offer for adoptable children and with the increasing pressure from the birth countries of children to make host countries adopt children with high age or with special needs. It also requires from the administrations the will to provide better initial information and to implement the demand for an agreement. Meanwhile, in spite of those growing constraints, adopting families have been more and more risk adverse during the latest decades, this being a common trend in our developed countries.

    The worldHealth Organization's (WHO's) International Program for Chemical Safety has developed a framework for performing risk assessments that integrate the assessment of risks to human health and risks to nonhuman organisms and ecosystems. The WHO's framework recognizes that stakeholders and risk managers have their own processes that are parallel to the scientific process of risk assessment and may interact with the risk assessment at various points, depending on the context. Integration of health and ecology provides consistent expressions of assessment results, incorporates the interdependence of humans and the environment, uses sentinel organisms, and improves the efficiency and quality of assessments relative to independent human health and ecological risk assessments. The advantage of the framework to toxicologists lies in the opportunity to use understanding of toxicokinetics and toxicodynamics to inform the integrated assessment of all exposed species.

    Eide, Steven Arvid; Thomas Wierman

    2003-12-01

    The Environment, Safety and Health Risk Assessment Program (ESHRAP) models human safety and health risk resulting from waste management and environmental restoration activities. Human safety and health risks include those associated with storing, handling, processing, transporting, and disposing of radionuclides and chemicals. Exposures to these materials, resulting from both accidents and normal, incident-free operation, are modeled. In addition, standard industrial risks (falls, explosions, transportation accidents, etc.) are evaluated. Finally, human safety and health impacts from cleanup of accidental releases of radionuclides and chemicals to the environment are estimated. Unlike environmental impact statements and safety analysis reports, ESHRAP risk predictions are meant to be best estimate, rather than bounding or conservatively high. Typically, ESHRAP studies involve risk predictions covering the entire waste management or environmental restoration program, including such activities as initial storage, handling, processing, interim storage, transportation, and final disposal. ESHRAP can be used to support complex environmental decision-making processes and to track risk reduction as activities progress.

    The health risk posed by arsenic in vegetables grown in private gardens near 22 contaminated glassworks sites was investigated in this study. Firstly, vegetable (lettuce and potato) and soil samples were collected and arsenic concentrations measured to characterize the arsenic uptake in the selected crops. Secondly, a probabilistic exposure assessment was conducted to estimate the average daily intake (ADIveg), which was then evaluated against toxicological reference values by the calculation of hazard quotients (HQs) and cancer risks (CRs). The results show that elevated arsenic concentrations in residential garden soils are mirrored by elevated concentrations in vegetables, and that consumption of these vegetables alone may result in an unacceptable cancer risk; the calculated reasonable maximum exposure, for example, corresponded to a cancer incidence 20 times higher than the stated tolerance limit. However, the characterization of risk depends to a great extent on which toxicological reference value is used for comparison, as well as how the exposure is determined. Based on the assumptions made in the present study, the threshold levels for chronic non-carcinogenic or acute effects were not exceeded, but the cancer risks indicated highlight the need for further exposure studies, as dietary intake involves more than just homegrown vegetables and total exposure is a function of more than just one exposure pathway. In addition, glassworks sites--and contaminated sites in general--contain multiple contaminants, affecting the final and total risk. PMID:26204055

    Public concern regarding activities involving radioactive material generally focuses on the human health risk associated with exposure to ionizing radiation. This report describes the results of a risk analysis conducted to evaluate risk for excavation, handling, and transport of soil contaminated with transuranics at the Clean Slate sites. Transportation risks were estimated for public transport routes from the Tonopah Test Range (TTR) to the Envirocore disposal facility or to the Area 3 Radioactive Waste Management Site (RWMS) at the Nevada Test Site (NTS) for both radiological risk and risk due to traffic accidents. Human health risks were evaluated for occupational and radiation-related health effects to workers. This report was generated to respond to this public concern, to provide an evaluation of the risk, and to assess feasibility of transport of the contaminated soil for disposal.

  18. Perceived and calculated health risks: do the impacts differ

    1986-01-23

    In many cases of radioactive and hazardous waste management, some members of the general public perceive that human health risks associated with the wastes are higher than the calculated risks. Calculated risks are projections that have been derived from models, and it is these risks that are usually used as the basis for waste management. However, for various reasons, the calculated risks are often considered by the public as too low or inappropriate. The reasons that calculated risks are not perceived as accurate and the factors that affect these perceptions are explored in this paper. Also discussed are the impacts related to the perceived and calculated health risks: what they are, and if and how they differ. The kinds of potential impacts examined are health effects, land value changes, and social, transportation, and economic effects. The paper concludes with a discussion of the implications of incorporating these different risk perspectives in decisions on waste management.

    Financial, geophysical, and terrorist-related disasters have been headline news in the past few months. As amply demonstrated on a regular basis, the recognition and evaluation of risks are skills that could be more widespread. As such, Proske's Catalogue of Risks is timely and of potential interest. The book is a revised and expanded version of an earlier German publication that aims to provide an encyclopedic discussion of issues related to risks and disasters, with a goal of facilitating an understanding of the components and assessment of risk. The book includes chapters that discuss the difficulty of coming to a consensus on a definition of risk, a comprehensive range of risks and disasters, objective risk measures, subjective risk judgment, quality of life measures, and legal aspects of risk. The book ends with an example of applying the concepts discussed to ship impacts against bridges.

    Health Impact Assessment (HIA) is a developing component of the overall impact assessment process and as such needs access to procedures that can enable more consistent approaches to the stepwise process that is now generally accepted in both EIA and HIA. The guidelines developed during this project provide a structured process, based on risk assessment procedures which use consequences and likelihood, as a way of ranking risks to adverse health outcomes from activities subjected to HIA or HIA as part of EIA. The aim is to assess the potential for both acute and chronic health outcomes. The consequences component also identifies a series of consequences for the health care system, depicted as expressions of financial expenditure and the capacity of the health system. These more specific health risk assessment characteristics should provide for a broader consideration of health consequences and a more consistent estimation of the adverse health risks of a proposed development at both the scoping and risk assessment stages of the HIA process. - Highlights: Black-Right-Pointing-Pointer A more objective approach to health risk assessment is provided. Black-Right-Pointing-Pointer An objective set of criteria for the consequences for chronic and acute impacts. Black-Right-Pointing-Pointer An objective set of criteria for the consequences on the health care system.

  1. Weighing health benefit and health risk information when consuming sport-caught fish.

    2003-12-01

    Fish consumers may incur benefits and risks from eating fish. Health advisories issued by states, tribes, and other entities typically include advice about how to limit fish consumption or change other behaviors (e.g., fish cleaning or cooking) to reduce health risks from exposure to contaminants. Eating fish, however, may provide health benefits. Risk communicators and fish consumers have suggested the importance of including risk comparison information, as well as health risk-benefit comparisons in health advisory communications. To improve understanding about how anglers fishing in waters affected by health advisories may respond to such risk-risk or risk-benefit information, we surveyed Lake Ontario (NY, USA) anglers. We interviewed by telephone 4,750 anglers, 2,593 of which had fished Lake Ontario in the past 12 months and were sent a detailed mail questionnaire (1,245 responded). We posed questions varying the magnitude of health risks and health benefits to be gained by fish consumption, and varied the population affected by these risks and benefits (anglers, children, women of childbearing age, and unborn children). Respondents were influenced by health benefit and health risk information. When risks were high, most respondents would eat less fish regardless of the benefit level. When risks were low, the magnitude of change in fish consumption was related to level of benefit. Responses differed depending on the question wording order, that is, whether "risks" were posed before "benefits." For a given risk-benefit level, respondents would give different advice to women of childbearing age versus children, with more conservative advice (eat less fish) provided to women of childbearing age. Respondents appeared to be influenced more strongly by risk-risk comparisons (e.g., risks from other foods vs. risks from fish) than by risk-benefit comparisons (e.g., risks from fish vs. benefits from fish). Risk analysts and risk communicators should improve efforts to include risk-risk and risk-benefit comparisons in communication efforts, and to clarify to whom the health risks and benefits from fish consumption may accrue.

  2. Health literacy among university students in Greece: determinants and association with self-perceived health, health behaviours and health risks

    2014-01-01

    Background Health literacy is widely considered as a key determinant of health and a priority in the public health policy agenda. Low health literacy has been associated with poorer health states, broader inequalities and higher health systems’ costs. In the present study we bring into focus the functional health literacy among university students in Greece, researching and assessing mainly their ability to apply basic knowledge in a health context. Methods The study was carried out during the period 15–30 April 2013, among a random sample of 1,526 students of 14 Higher Tertiary Public universities and Technological Educational Institutes in Greece. The objective of the study was to assess the functional health literacy among university students in Greece, adopting the short four-item comprehension test of Bostock and Steptoe. Summary statistics, correlations and regressions were used to assess the determinants of health literacy and the association with self-perceived health, health behaviours and health risks. Results Economic factors, such as family income, demographic factors, such as gender, and health behaviours and risks, namely consumption of alcohol, smoking and physical workout are associated with the level of health literacy and health status of the participant. While the results of the study are consistent with previous work in this area, several findings worth further research. Conclusions Though, health promotion interventions in Greece include health literacy as one of the basic pillars of the public health policy agenda, it is clear, that health literacy needs to become a key policy issue in Greece, mainly focusing in young ages, where healthy (or unhealthy) behaviours are established affecting the health through the life span.

    Risk matrices (RMs) are commonly used to evaluate health and safety risks. Nonetheless, they violate some theoretical principles that compromise their feasibility and use. This study describes how multiple criteria decision analysis methods have been used to improve the design and the deployment of RMs to evaluate health and safety risks at the Occupational Health and Safety Unit (OHSU) of the Regional Health Administration of Lisbon and Tagus Valley. ‘Value risk-matrices’ (VRMs) are built with the MACBETH approach in four modelling steps: a) structuring risk impacts, involving the construction of descriptors of impact that link risk events with health impacts and are informed by scientific evidence; b) generating a value measurement scale of risk impacts, by applying the MACBETH-Choquet procedure; c) building a system for eliciting subjective probabilities that makes use of a numerical probability scale that was constructed with MACBETH qualitative judgments on likelihood; d) and defining a classification colouring scheme for the VRM. A VRM built with OHSU members was implemented in a decision support system which will be used by OHSU members to evaluate health and safety risks and to identify risk mitigation actions.

    We developed a risk-based, multi-pollutant air quality health index (AQHI) reporting system in Hong Kong, based on the Canadian approach. We performed time series studies to obtain the relative risks of hospital admissions for respiratory and cardiovascular diseases associated with four air pollutants: sulphur dioxide, nitrogen dioxide, ozone, and particulate matter with an aerodynamic diameter less than 10 ?m (PM10). We then calculated the sum of excess risks of the hospital admissions associated with these air pollutants. The cut-off points of the summed excess risk, for the issuance of different health warnings, were based on the concentrations of these pollutants recommended as short-term Air Quality Guidelines by the World Health Organization. The excess risks were adjusted downwards for young children and the elderly. Health risk was grouped into five categories and sub-divided into eleven bands, with equal increments in excess risk from band 1 up to band 10 (the 11th band is 'band 10+'). We developed health warning messages for the general public, including at-risk groups: young children, the elderly, and people with pre-existing cardiac or respiratory diseases. The new system addressed two major shortcomings of the current standard-based system; namely, the time lag between a sudden rise in air pollutant concentrations and the issue of a health warning, and the reliance on one dominant pollutant to calculate the index. Hence, the AQHI represents an improvement over Hong Kong's existing air pollution index.

    Despite being part of a large and legal industry in Los Angeles, little is known about adult film performers’ exposure to health risks and when and how these risks might occur. The objective was to identify exposure to physical, mental, and social health risks and the pathways to such risks among adult film performers and to determine how risks differ between different types of performers, such as men and women. Semi-structured in-depth interviews were conducted with 18 female and ten male performers as well as two key informants from the industry. Performers and key informants were recruited through Protecting Adult Welfare, adult film venues, and snowball sampling. Performers engaged in risky health behaviors that included high-risk sexual acts that are unprotected, substance abuse, and body enhancement. They are exposed to physical trauma on the film set. Many entered and left the industry with financial insecurity and suffered from mental health problems. Women were more likely than men to be exposed to health risks. Adult film performers, especially women, are exposed to health risks that accumulate over time and that are not limited to sexually transmitted diseases. PMID:18709554

    Objective: Primary aluminum production is an industrial process with high potential health risk for workers. We consider in this article how to assess community health risks associated with primary aluminum smelter emissions. Methods: We reviewed the literature on health effects, community exposure data, and dose–response relationships of the principal hazardous agents emitted. Results: On the basis of representative measured community exposure levels, we were able to make rough estimates on health risks associated with specific agents and categorize these as none, low, medium, or high. Conclusions: It is possible to undertake a rough-estimate community Health Risk Assessment for individual smelters on the basis of information available in the epidemiological literature and local community exposure data.

    Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

  9. Living arrangements, knowledge of health risks, and stress as determinants of health-risk behavior among college students.

    PubMed

    Jones, D H; Harel, Y; Levinson, R M

    1992-09-01

    The association of knowledge of health risks, living arrangements, and perceived stress with health-risk behaviors was examined in a sample of college students included in the Health Promotion and Disease Prevention Supplement of the National Health Interview Survey. Regressions of each health-risk behavior (dependent variable) were performed on the predicted correlates. Although knowledge was not associated with participation in physical activity or smoking, the study found that students who knew more about the harmful effects of alcohol drank less, and those with greater knowledge of health risks practiced fewer risky behaviors. Students living independently were more likely to smoke, and those living in residence halls were less like to do so. Drinking, however, was more common among students living in residence halls or independently than among those living at home. Hall residents engaged in more group physical activity than other students did, but their physical activity was unrelated to health-risk behaviors. Stress was associated with smoking but not with other health practices. The findings suggest that smoking may be less influenced by health knowledge and more associated than drinking is with a response to stress. Drinking appears to be a social activity associated with living among peers and is potentially modifiable by increased knowledge about the effects of alcohol on health. PMID:1460172

    Objective We sought to examine the legal and ethical implications of workplace health risk reduction programs (HRRPs) using health risk assessments, individually focused risk reduction, and financial incentives to promote compliance. Methods We conducted a literature review, analyzed relevant statutes and regulations, and considered the effects of these programs on employee health privacy. Results A variety of laws regulate HRRPs, and there is little evidence that employer-sponsored HRRPs violate these provisions; infringement on individual health privacy is more difficult to assess. Conclusion Although current laws permit a wide range of employer health promotion activities, HRRPs also may entail largely unquantifiable costs to employee privacy and related interests.

    Qualitative description was used to explore how rural community leaders frame, interpret, and give meaning to environmental health issues affecting their constituents and communities. Six rural community leaders discussed growth, vulnerable families, and the action avoidance strategies they use or see used in lieu of adopting health-promoting behaviors. Findings suggest intervention strategies should be economical, use common sense, be sensitive to regional identity, and use local case studies and “inside leadership.” Occupational health nurses addressing the disparate environmental health risks in rural communities are encouraged to use agenda-neutral, scientifically based risk communication efforts and foster collaborative relationships among nurses, planners, industry, and other community leaders.

    Kasturba Hospital in Sevagram, India, has helped to initiate an outreach health program for nearby villages. A health insurance scheme has evolved where the community contributes sorghum for a fund and participates in decision-making and the supervision of village health workers. Contributors are entitled to free primary care and subsidized referral care. Only villages where at least 75% of the poor community agreed to enroll in the health insurance scheme were adopted by the hospital. The hospital offers insured persons free inpatient treatment for unexpected illness and a 75% subsidy for care during normal pregnancy or with cataract and hernia operations. The mobile health team, comprising auxiliary nurse-midwife, social worker, and village health worker, provides maternal and child health services in the localities. The village health workers provide symptomatic drug treatment, exercise a preventive role with the help of visiting health team members, and refer patients to hospital. The auxiliary nurse-midwife and social workers organize visits for vaccination and provide maternal and child health care. The doctor in charge treats patients in the hospital and trains village health workers. More than 75% of the villages in the area have enrolled in the scheme over the last 10 years. No vaccine-preventable illness (measles, poliomyelitis, diphtheria, whooping cough, tetanus) was reported in children or mothers after mass immunization was instituted, no maternal deaths have occurred during the past 10 years, and perinatal mortality has fallen steeply. The village health teams are now regarded as counselors on health-related matters, among them drinking-water supplies, irrigation, and programs for income generation. It is necessary to regulate the private health sector, including professionals, the drug industry, and investors. If outpatient services are opened up to the private sector, a system of universal medical insurance, financed by local government, should operate. PMID:1418330

    2014-01-01

    Legionella is an opportunistic pathogen of public health concern. Current regulatory and management guidelines for the control of this organism are informed by risk assessments. However, there are many unanswered questions and uncertainties regarding Legionella epidemiology, strain infectivity, infectious dose, and detection methods. This review follows the EnHealth Risk Assessment Framework, to examine the current information available regarding Legionella risk and discuss the uncertainties and assumptions. This review can be used as a tool for understanding the uncertainties associated with Legionella risk assessment. It also serves to highlight the areas of Legionella research that require future focus. Improvement of these uncertainties will provide information to enhance risk management practices for Legionella, potentially improving public health protection and reducing the economic costs by streamlining current management practices.

    Objectives Environmental exposures during pregnancy have a lasting impact on children's health. We combined environmental and maternal risk factor survey data to inform efforts to protect children's health. We made recommendations for future use of such data. Methods A modified version of the Pregnancy Risk Assessment Monitoring System(PRAMS) mail survey was conducted based on weighted sampling design with low-income and non-low income women in Monroe County, NY (1022 respondents). A series of environmental questions were included in the questionnaire. Data were analyzed using chi-square tests and Poisson loglinear regression model to identify patterns in environmental health risk and sociodemographic characteristics. Results We identified women who rented their homes, had lower incomes, and lived in inner city zip codes as “high environmental health risk” (HEHR). HEHR respondents were more likely to report that a health care provider talked with them about lead and on average reported more behaviors to protect their children from lead poisoning. Conclusions Combining environmental and perinatal risk factor data could yield important recommendations for medical practice, health education, and policy development. However, at present PRAMS gathers only limited and inconsistent environmental data. We found that existing PRAMS environmental questions are insufficient. Further work is needed to develop updated and more comprehensive environmental health survey questions and implement them consistently across the country. PMID:23955384

  6. Health risk factors and self-rated health among job-seekers

    PubMed Central

    2011-01-01

    Background To determine a) proportions of behavior related health risk factors among job-seekers and b) to what extend these are related to self-rated health. Methods Over 12 months, job-seekers were recruited at three job-agencies in northeastern Germany. Among all individuals eligible for study inclusion, 7,906 (79.8%) provided information on smoking, risky drinking, overweight/obesity (body mass index), fruit and vegetable intake, physical inactivity, illicit drug use, and self-rated health. Proportions and 95% confidence intervals stratified by gender, age and duration of unemployment were calculated. Multivariate logistic regression analyses predicting self-rated health were conducted. Results The proportions of each health-risk factor were high, and 52.4% of the sample (53.4% male, 33.5 years mean age) had 3 or more health risk factors. Mostly, the proportions were particularly high among men and long-term unemployed individuals; e.g. 84.8% of the 18-24 year old long-term unemployed men were current smokers. Proportions of substance use related health risk factors were highest among the 18-24 year olds (e.g. risky drinking 28.7%), and proportions of health risk factors related to nutrition and physical inactivity were highest among the 40-64 year olds (e.g. overweight/obesity 65.4%). Depending on gender, all health risk factors and having 3 or more health risk factors were associated with lower self-rated health; odd ratios ranged between 1.2 for smoking (95% CI: 1.0-1.3) and 1.7 for overweight and physical inactivity (95% CI: 1.5-1.9). Conclusions Prevention efforts to reduce health risk factors and to increase health among job-seekers are needed, and job agencies appear a feasible setting for their implementation. PMID:21854611

    2014-01-01

    Introduction Multiple insurance funds serving different population groups may compromise equity due to differential revenue raising capacity and an unequal distribution of high risk members among the funds. This occurs when the funds exist without mechanisms in place to promote income and risk cross-subsidisation across the funds. This paper analyses whether the risk distribution varies across the Community Health Fund (CHF) and National Health Insurance Fund (NHIF) in two districts in Tanzania. Specifically we aim to 1) identify risk factors associated with increased utilisation of health services and 2) compare the distribution of identified risk factors among the CHF, NHIF and non-member households. Methods Data was collected from a survey of 695 households. A multivariate logisitic regression model was used to identify risk factors for increased health care utilisation. Chi-square tests were performed to test whether the distribution of identified risk factors varied across the CHF, NHIF and non-member households. Results There was a higher concentration of identified risk factors among CHF households compared to those of the NHIF. Non-member households have a similar wealth status to CHF households, but a lower concentration of identified risk factors. Conclusion Mechanisms for broader risk spreading and cross-subsidisation across the funds are necessary for the promotion of equity. These include risk equalisation to adjust for differential risk distribution and revenue raising capacity of the funds. Expansion of CHF coverage is equally important, by addressing non-financial barriers to CHF enrolment to encourage wealthy non-members to join, as well as subsidised membership for the poorest.

    Personal health reflects harmony between individual and experience; it is optimal homeostasis. Disease is an outcome of incongruity leading to dishomeostasis. Relative to earlier times, disease in modern society has higher "heritability" (in the broad meaning of the term). Inherited risks are facts compatible with anticipation and prevention of disease. This viewpoint has major implications for medical practice, deployment of health services, themes of research, and education of health care personnel and citizens. PMID:6763817

    2015-11-01

    There is a widespread need for the use of quantitative microbial risk assessment (QMRA) to determine reclaimed water quality for specific uses, however neither faecal indicator levels nor pathogen concentrations alone are adequate for assessing exposure health risk. The aim of this study was to build a conceptual model representing factors contributing to the microbiological health risks of reusing water treated in maturation ponds. This paper describes the development of an unparameterised model that provides a visual representation of theoretical constructs and variables of interest. Information was collected from the peer-reviewed literature and through consultation with experts from regulatory authorities and academic disciplines. In this paper we explore how, considering microbial risk as a modular system, following the QMRA framework enables incorporation of the many factors influencing human exposure and dose response, to better characterise likely human health impacts. By using and expanding upon the QMRA framework we deliver new insights into this important field of environmental exposures. We present a conceptual model of health risk of microbial exposure which can be used for maturation ponds and, more importantly, as a generic tool to assess health risk in diverse wastewater reuse scenarios.

  15. Risk equalisation and voluntary health insurance: The South Africa experience.

    PubMed

    McLeod, Heather; Grobler, Pieter

    2010-11-01

    South Africa intends implementing major reforms in the financing of healthcare. Free market reforms in private health insurance in the late 1980s have been reversed by the new democratic government since 1994 with the re-introduction of open enrolment, community rating and minimum benefits. A system of national health insurance with income cross-subsidies, risk-adjusted payments and mandatory membership has been envisaged in policy papers since 1994. Subsequent work has seen the design of a Risk Equalisation Fund intended to operate between competing private health insurance funds. The paper outlines the South African health system and describes the risk equalisation formula that has been developed. The risk factors are age, gender, maternity events, numbers with certain chronic diseases and numbers with multiple chronic diseases. The Risk Equalisation Fund has been operating in shadow mode since 2005 with data being collected but no money changing hands. The South African experience of risk equalisation is of wider interest as it demonstrates an attempt to introduce more solidarity into a small but highly competitive private insurance market. The measures taken to combat over-reporting of chronic disease should be useful for countries or funders considering adding chronic disease to their risk equalisation formulae. PMID:20619476

    Ameratunga, Rohan; Crooks, Christine; Simmons, Greg; Woon, See-Tarn

    2016-01-25

    Functional foods have become increasingly popular with consumers anxious to mitigate the effects of an unhealthy lifestyle or aging. In spite of attractive health claims, these products do not have legal or regulatory status in most countries and are regulated through their health claims. Regulation of functional foods by health claims does not address health risks and adverse effects of these products. In this essay regulatory aspects of functional foods are reviewed along with adverse effects published in the peer-reviewed literature. We detail why the lack of an internationally accepted definition of functional foods places consumers at risk of adverse outcomes. Our review will assist regulatory agencies, manufacturers and consumer groups to assess the benefits and reduce the risks associated with these products. PMID:25163007

    In two important health policy contexts – private plans in Medicare and the new state-run “Exchanges” created as part of the Affordable Care Act (ACA) – plan payments come from two sources: risk-adjusted payments from a Regulator and premiums charged to individual enrollees. This paper derives principles for integrating risk-adjusted payments and premium policy in individual health insurance markets based on fitting total plan payments to health plan costs per person as closely as possible. A least squares regression including both health status and variables used in premiums reveals the weights a Regulator should put on risk adjusters when markets determine premiums. We apply the methods to an Exchange-eligible population drawn from the Medical Expenditure Panel Survey (MEPS). PMID:24308878

  20. [Health alert management and emerging risk].

    Following health crisis that have occurred in the nineties (contaminated blood, mad cow, asbestos, etc.) and more recently those generated by the heat wave in 2003 or by emerging infectious pathogens (SARS, West Nile, Chikungunya, H5N1, H1N1…), a real health vigilance system has been progressively developed in France. After a brief historical overview of the health alert system, this article will give the guiding principles of its current organization in France and will present two examples of recent health alerts (Chikungunya in the Reunion Island in 2005-2006 and hepatitis A outbreak in the Côtes-d'Armor in August 2007), that have needed the implementation of preventive measures regarding the blood donor selection. These two examples have shown that the position of the alert in the French health vigilance system needs to be very close to the event. In that case, health alert is a very useful tool for decision making especially when measures have to be taken to prevent transfusion-transmitted pathogens. PMID:21051258

    Since its introduction some two decades ago, health risk appraisal (HRA) has become a standard offering in the health promotion repertoire. The technique's distinctive feature is its use of epidemiologic data to generate quantitative risk messages for the client. Yet despite the dedication and considerable investments that have gone into HRA's development, dissemination, and use, there is only limited empirical evidence that these quantitative risk messages have any effect on clients. There do not appear to be any formal studies of HRA's effect on participation in health promotion programs, although increasing recruitment is regarded as a major benefit of using HRA. There are few indications of HRA effects on health beliefs. Most positive reports of effects on behavior change come from uncontrolled studies; several randomized controlled trials have yielded ambiguous findings. Virtually no data exist concerning the impact of the quantitative risk messages that distinguish HRA from other assessment techniques and that have motivated the substantial efforts toward developing and refining HRA. HRA has evident appeal and is probably a useful health education device for middle-class, middle-aged, nonminority clients. It may well have desirable effects on health-related beliefs, attitudes, and behaviors when accompanied by counseling or education, but available evidence has not established its effectiveness. Given the difficulty of obtaining definitive evidence of the effectiveness of HRA and specifically of its use of quantitative risk projections, the need for such evidence is debatable. An adequately funded and reviewed research program to examine whether projections of absolute risk affect knowledge, beliefs, attitudes, and intention to change is recommended as the most fruitful next step. Epidemiologically based HRA procedures that provide feedback in terms of qualitative statements or relative risk may be a promising approach to prospective health assessment. PMID:3679843

    Reliable and comparable analysis of risks to health is key for preventing disease and injury. Causal attribution of morbidity and mortality to risk factors has traditionally been conducted in the context of methodological traditions of individual risk factors, often in a limited number of settings, restricting comparability. In this paper, we discuss the conceptual and methodological issues for quantifying the population health effects of individual or groups of risk factors in various levels of causality using knowledge from different scientific disciplines. The issues include: comparing the burden of disease due to the observed exposure distribution in a population with the burden from a hypothetical distribution or series of distributions, rather than a single reference level such as non-exposed; considering the multiple stages in the causal network of interactions among risk factor(s) and disease outcome to allow making inferences about some combinations of risk factors for which epidemiological studies have not been conducted, including the joint effects of multiple risk factors; calculating the health loss due to risk factor(s) as a time-indexed "stream" of disease burden due to a time-indexed "stream" of exposure, including consideration of discounting; and the sources of uncertainty.

    This study gathered health inspectors' opinions about appropriate weightings of critical, noncritical, and repeat violations under the current food inspection system, and developed a classification of violations for high-, medium-, and low-risk restaurants. Results showed that health inspectors thought that the appropriate weights were five points for a critical violation, one point for a noncritical violation, and double points for a repeat violation. In addition, health inspectors thought that the maximum numbers of critical violations for a high-, medium-, and low-risk category were 2.05, 3.02, and 4.83, respectively, and for noncritical violations, 4.59, 7.30, and 10.37, respectively. A paired t-test was used to compare these values with estimations based on the traditional health inspection scoring system. Results indicate that the maximum number of critical violations for medium risk and maximum numbers of noncritical violations for low-, medium-, or high-risk restaurants were significantly different between health inspectors' opinions and mathematical estimations. Health inspectors appear to be stricter than the traditional health inspection scoring system about violations, particularly repeat violations, and their importance in enforcement of food safety.

    The possibility of using in vitro testing to determine the equivalence of risk for various occupational groups is discussed. In the absence of epidemiological evidence or relevant animal in vivo bioassays on which to determine the health effects of specific occupational exposures, it is proposed to use similarities in the in vitro response to substances with known (or strongly suspected) and unknown risk to demonstrate their risk equivalence. Identification and evaluation of a high risk "hot spot" due to exposure to Cr(VI) for stainless steel welders is discussed in terms of recent developments in collection, analysis and bioassay of welding fumes.

    In order to provide better sustainable groundwater quality management and minimize the impact of contamination in humans, improved understanding and quantification of the interaction between hydrogeological models, geological site information and human health are needed. Considering the joint influence of these components in the overall human health risk assessment and the corresponding sources of uncertainty aid decision makers to better allocate resources in data acquisition campaigns. This is important to (1) achieve remediation goals in a cost-effective manner, (2) protect human health and (3) keep water supplies clean in order to keep with quality standards. Such task is challenging since a full characterization of the subsurface is unfeasible due to financial and technological constraints. In addition, human exposure and physiological response to contamination are subject to uncertainty and variability. Normally, sampling strategies are developed with the goal of reducing uncertainty, but less often they are developed in the context of their impacts on the overall system uncertainty. Therefore, quantifying the impact from each of these components (hydrogeological, behavioral and physiological) in final human health risk prediction can provide guidance for decision makers to best allocate resources towards minimal prediction uncertainty. In this presentation, a multi-component human health risk-based framework is presented which allows decision makers to set priorities through an information entropy-based visualization tool. Results highlight the role of characteristic length-scales characterizing flow and transport in determining data needs within an integrated hydrogeological-health framework. Conditions where uncertainty reduction in human health risk predictions may benefit from better understanding of the health component, as opposed to a more detailed hydrogeological characterization, are also discussed. Finally, results illustrate how different dose-response models can impact the probability of human health risk exceeding a regulatory threshold.

    2009-01-01

    Summary The tracking of sentinel health events in humans in order to detect and manage disease risks facing a larger population is a well accepted technique applied to influenza, occupational conditions, and emerging infectious diseases. Similarly, animal health professionals routinely track disease events in sentinel animal colonies and sentinel herds. The use of animals as sentinels for human health threats, or of humans as sentinels for animal disease risk, dates back at least to the era when coal miners brought caged canaries into mines to provide early warning of toxic gases. Yet the full potential of linking animal and human health information to provide warning of such “shared risks” from environmental hazards has not been realized. Reasons appear to include the professional segregation of human and animal health communities, the separation of human and animal surveillance data, and evidence gaps in the linkages between human and animal responses to environmental health hazards. The One Health initiative and growing international collaboration in response to pandemic threats, coupled with development the fields of informatics and genomics, hold promise for improved sharing of knowledge about sentinel events in order to detect and reduce environmental health threats shared between species.

    Hypogonadism is prevalent in older men and testosterone replacement therapy (TRT) for older hypogonadal men is a promising therapy. However, a number of important clinical concerns over TRT safety remain unsolved due to a lack of large-scale randomized clinical trials directly comparing the health risks of untreated hypogonadism vs long-term use of TRT. Meta-analyses of clinical trials of TRT as of 2010 have identified three major adverse events resulting from TRT: polycythemia, an increase in prostate-related events, and a slight reduction in serum high-density lipoprotein cholesterol. There are other purported health risks but their incidence can be neither confirmed nor denied based on the small number of subjects that have been studied to date. Furthermore, subsequent literature is equivocal with regard to the safety and utility of TRT and this topic has been subject to contentious debate. Since January 2014, the United States Food and Drug Administration has released two official announcements regarding the safety of TRT and clinical monitoring the risks in TRT users. Additionally, the health risks related to the clinical presentation of low or declining testosterone levels not been resolved in the current literature. Because TRT is prescribed in the context of putative risks resulting from reduced testosterone levels, we reviewed the epidemiology and reported risks of low testosterone levels. We also highlight the current information about TRT utilization, the risks most often claimed to be associated with TRT, and current or emerging alternatives to TRT. PMID:25879005

    Irradiated topaz gemstones are currently processed for color improvement by subjecting clear stones to neutron or high-energy electron irradiations, which leads to activation of trace elements in the stones. Assessment of the risk to consumers required the identification and quantification of the resultant radionuclides and the attendant exposure. Representative stones from Brazil, India, Nigeria, Sri Lanka were irradiated and analyzed for gamma ray and beta particle emissions, using sodium iodide and germanium spectrometers; and Geiger-Muller, plastic and liquid scintillation, autoradiography, and thermoluminescent-dosimetry measurement techniques. Based on these studies and other information derived from published literature, dose and related risk estimates were made for typical user conditions. New criteria and methods for routine assays for acceptable release, based on gross beta and gross photon emissions from the stones, were also developed.

    Superfund conjures up images of hazardous waste sites, which EPA is spending billions of dollars to remediate. One of the law's most worrisome effects is that it drains enormous economic resources without returning commensurate benefits. In a Sept. 1, 1991, front page article in The New York Times, experts argued that most health dangers at Superfund sites could be eliminated for a fraction of the billions that will be spent cleaning up the 1,200 high-priority sites across the country. Even EPA has suggested that the Superfund program may receive disproportionate resources, compared with other public health programs, such as radon in houses, the diminishing ozone layer and occupational diseases. Public opinion polls over the last decade consistently have mirrored the public's vast fear of hazardous waste sites, a fear as great as that held for nuclear power plants. Fear notwithstanding, the high cost of chosen remedies at given sites may have less to do with public health goals than with the method EPA uses to translate them into acceptable contaminant concentrations in soil, groundwater and other environmental media.

    In the face of limited resources and an aging population with increasingly care needs, healthcare systems must identify community-dwelling older adults with mental health problems at higher risk of adverse outcomes such as institutionalization, hospitalization and death, in order to deliver timely and efficient care. The objectives of this study were to assess the prevalence of mental health concerns and the associated perceived risk of adverse outcomes in a large sample of older patients in primary care (PC). We trained general practitioners and nurses to use the Risk Instrument for Screening in the Community to rank perceived risk of mental health concerns (including neurocognitive and mood disorders) from 1 (mild) to 3 (severe). The mean age of the 4499 people assessed was 76.3 years (SD = 7.3) and 2645 (58.8%) were female. According to the PC team 1616 (35.9%) were perceived to have mental health concerns of whom 847 (52.4%) were mild, 559 (34.6%) were moderate and 210 (13%) were severe. Patients with mental health concerns had higher odds of perceived risk of adverse outcomes (OR = 2.22, 95% CI 1.83–2.69 for institutionalization; OR = 1.66, 95% CI 1.41–1.94 for hospitalization; OR = 1.69, 95% CI 1.42–2.01 for death). These results suggest a high prevalence of mental health concerns among older adults and supports the need for early identification of patients at high-risk of adverse healthcare outcomes.

    Lifestyle and health-related factors are critical components of the risk for cognitive aging among veterans. Because dementia has a prolonged prodromal phase, understanding effects across the life course could help focus the timing and duration of prevention targets. This perspective may be especially relevant for veterans and health behaviors. Military service may promote development and maintenance of healthy lifestyle behaviors, but the period directly after active duty has ended could be an important transition stage and opportunity to address some important risk factors. Targeting multiple pathways in one intervention may maximize efficiency and benefits for veterans. A recent review of modifiable risk factors for Alzheimer's disease estimated that a 25% reduction of a combination of seven modifiable risk factors including diabetes, hypertension, obesity, depression, physical inactivity, smoking, and education/cognitive inactivity could prevent up to 3 million cases worldwide and 492,000 cases in the United States. Lifestyle interventions to address cardiovascular health in veterans may serve as useful models with both physical and cognitive activity components, dietary intervention, and vascular risk factor management. Although the evidence is accumulating for lifestyle and health-related risk factors as well as military risk factors, more studies are needed to characterize these factors in veterans and to examine the potential interactions between them.

    The 1980s will be remembered by forest professionals as a decade of intense and widespread societal concern for the vitality and integrity of forest systems. Daily reports of tropical deforestation and temperate forest decline have heightened social consciousness of forest health. It is therefore appropriate, as we enter the 1990s, to assess the health of our forests and propose new initiatives in this critically important area. Making generalizations about the health of North American forests is difficult because of the extraordinary diversity of forests, management regimes, and stress factors. This overview article summarizes forest health fundamentals, significant health risks, and priorities in future forest health management for temperate forests of the United States.

    2014-01-01

    Background: The National Health Insurance Scheme (NHIS), operated majorly in Nigeria by health maintenance organisations (HMOs), took off formally in June 2005. In view of the inherent risks in the operation of any social health insurance, it is necessary to efficiently manage these risks for sustainability of the scheme. Consequently the risk-management strategies deployed by HMOs need regular assessment. This study assessed the risk management in the Nigeria social health insurance scheme among HMOs. Materials and Methods: Cross-sectional survey of 33 HMOs participating in the NHIS. Results: Utilisation of standard risk-management strategies by the HMOs was 11 (52.6%). The other risk-management strategies not utilised in the NHIS 10 (47.4%) were risk equalisation and reinsurance. As high as 11 (52.4%) of participating HMOs had a weak enrollee base (less than 30,000 and poor monthly premium and these impacted negatively on the HMOs such that a large percentage 12 (54.1%) were unable to meet up with their financial obligations. Most of the HMOs 15 (71.4%) participated in the Millennium development goal (MDG) maternal and child health insurance programme. Conclusions: Weak enrollee base and poor monthly premium predisposed the HMOs to financial risk which impacted negatively on the overall performance in service delivery in the NHIS, further worsened by the non-utilisation of risk equalisation and reinsurance as risk-management strategies in the NHIS. There is need to make the scheme compulsory and introduce risk equalisation and reinsurance. PMID:25298605

    Background: Mental health is an important component of the total positive health and is interwoven closely with the physical and physiological dynamics of the human body. Worldwide, about 500 million people are believed to be suffering from neurotic, stress related and psychological problems. In India, surveys on mental morbidity in various parts of the country suggest a prevalence rate of 18-20 per 1000. Materials and Methods: A community-based, cross-sectional descriptive study was carried out amongst married women in the age group 18-45 years in an urban community of South Mumbai. Self-reporting questionnaire of 20 items (SRQ 20) developed by the WHO was administered. Statistical analysis was carried out to estimate the prevalence of psychiatric disturbance. Result: The prevalence of psychiatric disturbance was found to be 27.27% for the total sample. The study results indicate that somatic symptoms were reported more commonly which could be a manifestation of underlying/burgeoning mental disorders. Conclusions: The results imply a high prevalence of 27.27% of psychiatric disturbance in our community. However, defining mental disorder from a clinical standpoint necessitates identification of the dividing line between despair and depression. It is recommended that women be encouraged to approach counsellors and thus enable further diagnosis and management of Common Mental Disorders in the community. PMID:24695680

    Cancer risk perceptions and cancer worry are shaped by race/ethnicity, and social, economic, and environmental factors, which in turn shape health decision-making. A paucity of studies has explored risk perceptions and worry in metropolitan areas with disparate environmental conditions and cancer outcomes. This study examined perceptions of cancer risk, neighborhood environmental health risks, and risk-reducing health behaviors among Blacks. A 59-item survey was administered to respondents in Metropolitan Charleston, South Carolina from March to September 2013. A convenience sample of males and females was recruited at local venues and community events. Descriptive statistics, bivariate analyses (Chi square tests), and logistic regression models were estimated using SAS 9.3 software. Respondents (N = 405) were 100% Black, 81% female (n = 323), and ranged from 18 to 87 years of age (M = 49.55, SD = 15.27). Most respondents reported lower perceptions of cancer risk (37%) and equated their cancer beliefs to direct or indirect (i.e. personal or family) experiences. Low perceived cancer risk (absolute risk) was significantly associated (p < .05) with non-alcohol consumption, having a colon cancer screening test, being female, and being age 25-44 or 45-64. Cancer worry was significantly associated (p < .05) with being a current smoker, having a "fair" diet, non-alcohol consumption, and having any colon cancer screening test. Perceived cancer risk is an important indicator of health behaviors among Blacks. Direct or indirect experiences with cancer and/or the environment and awareness of family history of cancer may explain cancer risk perceptions. PMID:25315713

    There was evaluated the risk to health in females employed in shift work, including night shifts. According to the data of periodical medical examinations health indices of 403 females employed in shift work, including night shifts, were compared with indices of 205 females--workers of administrative units of the same enterprise. Overall relative risk (RR) for the health disorder associated with the night shift was 1.2 (95%; confidence interval (CI): 1.09-1.28). A statistically significant increase in risk was observed in relation to uterine fibroids (OR 1.3; 95% CI: 1.06-1.54), mastopathy (OR 1.4; 95% CI: 1.2-1.6), inorganic sleep disorders (OR 8.8; 95% CI 2.6-29.8). At the boundary of the statistical significance there was the increase in the risk for obesity (OR 1.2; 95% C: 0.97-1.39), hypertension (OR 1.2; 95% CI, 0.9-1.5) and endometriosis (OR 1.5; 95% CI: 0.98-2.16). There was revealed an adverse effect of night shifts on the gestation course: ectopic pregnancy in the experimental group occurred 6.6 times more frequently than in the control group (95% CI: 0.87-50.2), and spontaneous abortion--1.7 times (95% CI: 0.95-3.22). The performed study has once again confirmed the negative impact of smoking on women's reproductive health: smoking women in the experimental group compared with the control group smokers had 2.7 times increased risk of uterine fibroids (within 1.06-7.0), the risk in non-smokers was significantly lower--1.2 (0.98-1.4). The findings suggest about a wide range of health problems related to employment on shift work, including night shifts, which indicates to the need for adoption of regulatory and preventive measures aimed to this professional group.

  6. Environmental health risk assessment and management for global climate change

    This environmental health risk assessment and management approach for atmospheric greenhouse gas (GHG) pollution is based almost entirely on IPCC AR5 (2014) content, but the IPCC does not make recommendations. Large climate model uncertainties may be large environmental health risks. In accordance with environmental health risk management, we use the standard (IPCC-endorsed) formula of risk as the product of magnitude times probability, with an extremely high standard of precaution. Atmospheric GHG pollution, causing global warming, climate change and ocean acidification, is increasing as fast as ever. Time is of the essence to inform and make recommendations to governments and the public. While the 2ºC target is the only formally agreed-upon policy limit, for the most vulnerable nations, a 1.5ºC limit is being considered by the UNFCCC Secretariat. The Climate Action Network International (2014), representing civil society, recommends that the 1.5ºC limit be kept open and that emissions decline from 2015. James Hansen et al (2013) have argued that 1ºC is the danger limit. Taking into account committed global warming, its millennial duration, multiple large sources of amplifying climate feedbacks and multiple adverse impacts of global warming and climate change on crops, and population health impacts, all the IPCC AR5 scenarios carry extreme environmental health risks to large human populations and to the future of humanity as a whole. Our risk consideration finds that 2ºC carries high risks of many catastrophic impacts, that 1.5ºC carries high risks of many disastrous impacts, and that 1ºC is the danger limit. IPCC AR4 (2007) showed that emissions must be reversed by 2015 for a 2ºC warming limit. For the IPCC AR5 only the best-case scenario RCP2.6, is projected to stay under 2ºC by 2100 but the upper range is just above 2ºC. It calls for emissions to decline by 2020. We recommend that for catastrophic environmental health risk aversion, emissions decline from 2015 (CAN International 2014), and if policy makers are limited to the IPCC AR5 we recommend RCP2.6, with emissions declining by 2020.

Health risk methodology allows, in principle, to obtain quantitative indices of the separate results of the impact on the health status of the citizens of metropolis that can be extremely effective in this area. The total cross-media riskfrom traffic pollution, drinking water quality, open ponds, noise, etc. permits to use of hygiene criteria in urban planning, insurance, taxation, etc. PMID:26031033

    The U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) Threat and Consequence Assessment Division (TCAD) within the National Homeland Security Research Center (NHSRC) has developed a tool for rapid communication of health risks and likelihood of exposure in preparation for terrorist incidents. The Emergency Consequence Assessment Tool (ECAT) is a secure web-based tool designed to make risk assessment and consequence management faster and easier for high priority terrorist threat scenarios. ECAT has been designed to function as 'defensive play-book' for health advisors, first responders, and decision-makers by presenting a series of evaluation templates for priority scenarios that can be modified for site-specific applications. Perhaps most importantly, the risk communication aspect is considered prior to an actual release event, so that management or legal advisors can concur on general risk communication content in preparation for press releases that can be anticipated in case of an actual emergency. ECAT serves as a one-stop source of information for retrieving toxicological properties for agents of concern, estimating exposure to these agents, characterizing health risks, and determining what actions need to be undertaken to mitigate the risks. ECAT has the capability to be used at a command post where inputs can be checked and communicated while the response continues in real time. This front-end planning is intended to fill the gap most commonly identified during tabletop exercises: a need for concise, timely, and informative risk communication to all parties. Training and customization of existing chemical and biological release scenarios with modeling of exposure to air and water, along with custom risk communication 'messages' intended for public, press, shareholders, and other partners enable more effective communication during times of crisis. For DOE, the ECAT could serve as a prototype that would be amenable to customization to include radioactive waste management or responses to catastrophic releases of radioactive material due to terrorist actions.

  11. Health benefits and risks of plant proteins.

    PubMed

    Krajcovicova-Kudlackova, M; Babinska, K; Valachovicova, M

    2005-01-01

    Plant proteins have a reduced content of essential amino acids in comparison to animal proteins. A significant reduction of limiting amino acids (methionine, lysine, tryptophan) means lower protein synthesis. In subjects with predominant or exclusive consumption of plant food a higher incidence of hypoproteinemia due to significant reduction of methionine and lysine intakes was observed. On the other hand, lower intake of these amino acids provides a preventive effect against cardiovascular disease via cholesterol regulation by an inhibited hepatic phospholipid metabolism. Vegetarians have a significantly higher intake of non-essential amino acids arginine and pyruvigenic amino acids glycine, alanine, serine. When plant protein is high in non-essential amino acids, down-regulation of insulin and up-regulation of glucagon is a logical consequence. The action of glucagon in the liver is mediated by stimulation of adenyl cyclase that raises cyclic-AMP (adenosine-3,5-monophosphate) concentrations. Cyclic-AMP down-regulates the synthesis of a number of enzymes required for de novo lipogenesis and cholesterol synthesis, up-regulates key gluconeogenic enzymes and the LDL receptors and decreases the IGF-1 activity (insulin-like growth factor). Cyclic-AMP thus provides a reduction of atherosclerosis risk factors as well as a retardation of cancer development. A sufficient consumption of plant proteins has the protective effects against chronic degenerative diseases (Tab. 2, Ref. 26). PMID:16201743

  19. Effects of suicide bereavement on mental health and suicide risk.

    2014-06-01

    Between 48 million and 500 million people are thought to experience suicide bereavement every year. Over the past decade, increased policy attention has been directed towards suicide bereavement, but with little evidence to describe the effect of exposure or to provide appropriate responses. We used a systematic approach to carry out a narrative review of studies of the effect of suicide bereavement on mortality, mental health, and social functioning, and compared them with effects from other bereavements. We found 57 studies that satisfied strict inclusion criteria. Results from these studies suggested that exposure to suicide of a close contact is associated with several negative health and social outcomes, depending on an individual's relationship to the deceased. These effects included an increased risk of suicide in partners bereaved by suicide, increased risk of required admission to psychiatric care for parents bereaved by the suicide of an offspring, increased risk of suicide in mothers bereaved by an adult child's suicide, and increased risk of depression in offspring bereaved by the suicide of a parent. Some evidence was shown for increased rejection and shame in people bereaved by suicide across a range of kinship groups when data were compared with reports of relatives bereaved by other violent deaths. Policy recommendations for support services after suicide bereavement heavily rely on the voluntary sector with little input from psychiatric services to address described risks. Policymakers should consider how to strengthen health and social care resources for people who have been bereaved by suicide to prevent avoidable mortality and distress. PMID:26360405

    The ethical debate surrounding the payment of living unrelated donors continues despite very little evidence regarding the outcome. The aim of this audit was to identify the scale of the problem and assess the results of patients undergoing these procedures. The large Indo-Asian population within our region has a high demand for renal replacement therapy and transplantation. These patients have a limited chance of receiving a transplant for several reasons and some resort to traveling abroad, against medical advice, to procure an unrelated donor kidney transplant. Following an initial audit in our region, a national audit was conducted within the UK. A total of 23 patients were identified, all of whom had done so against medical advice. Mortality from causes directly related to transplantation was high in this group (35%), as was graft loss. The overall rate of successful transplants was only 44% (overall graft loss was 56%) in the short term. The information regarding both donor and recipient, provided from the transplanting center, was inadequate in all cases. These results, which almost certainly represent an underestimate of an ongoing situation, reinforce the standpoint that organ trading is associated with unacceptable risks and poor outcomes. The basis of this trade in organs is based on monetary rather than clinical criteria and such exploitation of both donor and recipient lead us to conclude that this practice cannot be endorsed and even the most desperate dialysis patients should be reminded of the unacceptable risks involved in this practice.

    In the framework of the European project PASODOBLE (FP7), we set up downstream information services by combining environmental and health data with a view to support the health care community and to improve vulnerable people welfare. Indeed there is a profound relationship between human health, well-being and air pollution levels. The main objectives are to establish correlations between air quality, exposure of populations and their reactivity, to develop and validate air quality indexes and to construct a prediction model of this sanitary index. This index will be implemented on 3 European sites: Greece (Athens and Thessaloniki), the Netherlands and "Provence Alpes Côte d'Azur" (South East of France). The selected region and cities are among the most affected by the atmospheric pollution in Europe and leads to serious sanitary concerns. The service aims to provide up-to-date, detailed information on air quality discomfort. The Aggregate Risk Index is based on the Cairncross's concept, obtained from the Relative Risk associated with short-term exposure to common air pollutants and takes into account the possible effects of a mixture of pollutants. This communication tool, easy to use and intuitive, about the levels of air pollution and the associated health risks, will be used to communicate information to the general population, authorities and to the health care community and will provide advanced warning of potentially health-damaging air pollution events.

    We examined the association of muscular fitness with psychological positive health, health complaints, and health risk behaviors in 690 (n = 322 girls) Spanish children and adolescents (6-17.9 years old). Lower body muscular strength was assessed with the standing long jump test, and upper-body muscular strength was assessed with the throw basketball test. A muscular fitness index was computed by means of standardized measures of both tests. Psychosocial positive health, health complaints, and health risk behaviors were self-reported using the items of the Health Behavior in School-aged Children questionnaire. Psychological positive health indicators included the following: perceived health status, life satisfaction, quality of family relationships, quality of peer relationships, and academic performance. We computed a health complaints index from 8 registered symptoms: headache, stomach ache, backache, feeling low, irritability or bad temper, feeling nervous, difficulties getting to sleep, and feeling dizzy. The health risk behavior indicators studied included tobacco use, alcohol use, and getting drunk. Children and adolescents with low muscular fitness (below the mean) had a higher odds ratio (OR) of reporting fair (vs. excellent) perceived health status, low life satisfaction (vs. very happy), low quality of family relationships (vs. very good), and low academic performance (vs. very good). Likewise, children and adolescents having low muscular fitness had a significantly higher OR of reporting smoking tobacco sometimes (vs. never), drinking alcohol sometimes (vs. never), and getting drunk sometimes (vs. never). The results of this study suggest a link between muscular fitness and psychological positive health and health risk behavior indicators in children and adolescents. PMID:22158258

    Objectives. We evaluated whether a program to prevent coronary heart disease (CHD) with community health workers (CHWs) would improve CHD risk in public health and health care settings. Methods. The CHWs provided point-of-service screening, education, and care coordination to residents in 34 primarily rural Colorado counties. The CHWs utilized motivational interviewing and navigated those at risk for CHD into medical care and lifestyle resources. A software application generated a real-time 10-year Framingham Risk Score (FRS) and guideline-based health recommendations while supporting longitudinal caseload tracking. We used multiple linear regression analysis to determine factors associated with changes in FRS. Results. From 2010 to 2011, among 4743 participants at risk for CHD, 53.5% received medical or lifestyle referrals and 698 were retested 3 or more months after screening. We observed statistically significant improvements in diet, weight, blood pressure, lipids, and FRS with the greatest effects among those with uncontrolled risk factors. Successful phone interaction by the CHW led to lower FRS at retests (P?=?.04). Conclusions. A CHW-based program within public health and health care settings improved CHD risk. Further exploration of factors related to improved outcomes is needed. PMID:23153152

    Identification and management the 'critical risk areas' where hotspot lead exposures are a potential risk to human health, become a major focus of public health efforts in China. But the knowledge of health risk assessment of lead pollution at regional and national scales is still limited in China. In this paper, under the guidance of 'sources-pathways-receptors' framework, regional human health risk assessment model for lead contamination was developed to calculate the population health risk in Yunnan province. And the cluster and AHP (analytic hierarchy process) analysis was taken to classify and calculate regional health risk and the decomposition of the regional health risk in the greatest health risk region, respectively. The results showed that Yunnan province can be divided into three areas. The highest health risk levels, located in northeastern Yunnan, including Kunming, Qujing, Zhaotong region. In those regions, lead is present at high levels in air, food, water and soil, and high population density which pose a high potential population risk to the public. The current study also reveals that most regional health risk was derived from the child receptors (age above 3 years) 4.3 times than the child receptors (age under 3years), and ingestion of lead-contaminated rice was found to be the most significant contributor to the health risk (accounting for more than 49 % health risk of total). This study can provide a framework for regional risk assessment in China and highlighted some indicators and uncertainties. PMID:25893826

    Conflicting opinions on the potential hazards associated with formaldehyde exposure triggered a national workshop to address the toxicological questions concerning the health effects of formaldehyde. Since quantitative human data are not available to derive a dose-response curve for formaldehyde risk assessment, nonhuman data are used. In the case of formaldehyde, data from animals exposed to high concentrations are used to estimate human risk at much lower concentrations. This study presents the several steps that make up a risk assessment and examines any additional data that might alter significantly the risk estimates presented in the 1984 EIS. Rat inhalation chronic bioassay data from a study sponsored by the Chemical Industry Institute of Toxicology (CIIT) have been used to develop a risk equation that was subsequently used by BPA in its EIS. The CIIT data base remains the only acceptable animal data that can support the estimation of a dose-response curve. The development of mathematical models continues with a great deal of energy, and the use of different models is largely responsible for the great variability of the formaldehyde risk estimates. While one can calculate different values for carcinogenic risk associated with formaldehyde exposure than were presented earlier in the BPA EIS, they are not likely to be any better.

    The physical demands of firefighting are extensive, and firefighters face increased risk of cardiovascular and metabolic disease, musculoskeletal injury, and cancer. To reduce these risks, a tailored wellness initiative program (FIT Firefighter) was developed and executed. Implementation of FIT Firefighter, consisting of assessment, educational, instructional, and personal coaching and training elements regarding nutrition, health, fitness, wellness, and strength and conditioning, revealed enhanced healthy behavior change including increased motivation and marked improvements in blood pressure, resting heart rate, aerobic fitness, body mass index, waist circumference, percent body fat, back flexibility, and biceps strength among participating firefighters.

    Calcining processes including handling and storage of raw petroleum coke may result in Particulate Matter (PM) and gaseous emissions. Concerns have been raised over the potential association between particulate and aerosol pollution and adverse respiratory health effects including decrements in lung function. This risk characterization evaluated the exposure concentrations of ambient air pollutants including PM10 and gaseous pollutants from a petroleum coke calciner facility. The ambient air pollutant levels were collected through monitors installed at multiple locations in the vicinity of the facility. The measured and modeled particulate levels in ambient air from the calciner facility were compared to standards protective of public health. The results indicated that exposure levels were, on occasions at sites farther from the facility, higher than the public health limit of 150 ?g/m(3) 24-h average for PM10. However, the carbon fraction demonstrated that the contribution from the calciner facility was de minimis. Exposure levels of the modeled SO2, CO, NOx and PM10 concentrations were also below public health air quality standards. These results demonstrate that emissions from calcining processes involving petroleum coke, at facilities that are well controlled, are below regulatory standards and are not expected to produce a public health risk.

    This study examined the longitudinal association between contextual stress and health risk behaviors and the role of protective factors in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling was used to create a latent variable measuring contextual stress (community violence, neighborhood disorder, and experiences with racial discrimination). Contextual stress in 8th grade was associated with aggressive behavior and substance use 2 years later for boys. For girls, contextual stress predicted later substance use, but not aggressive behavior. High academic competence and self-worth reduced the impact of contextual stress on substance use for boys. Implications for intervention and directions for future research on health risk behaviors among African American adolescents are discussed. PMID:20213481

    This paper presents a review of occupational risks and health disorders in professional drivers employed in public and private transport. Epidemiological studies suggest an excess risk for cardiovascular diseases and musculoskeletal disorders in several categories of professional drivers, such as bus drivers, taxi drivers, truck drivers and forklift truck drivers. Although cardiovascular and musculoskeletal disorders are of multifactorial origin, some characteristics of occupational exposure in transport drivers (stress, workshift, traffic pollutants, awkward postures, exposure to noise and whole body vibration) may exert at least a concausal role for the onset and the development of these disorders. The predominant role of some confounding factors (inappropriate diet, drinking and smoking habits) makes it more difficult to establish causal associations between professional driving and other adverse health effects (respiratory, gastrointestinal, and genito-urinary disorders, and neoplastic diseases).

    This study investigates the risk of arsenic (As) exposure to the residents in Pingtung Plain of Taiwan, where more than 50% of people extracts groundwater to meet the drinking purpose and monitoring groundwater shows that a considerable portion of groundwater has an As concentration of more than safe drinking water guideline of 10?g/L-1. Exposure and risk assessment are carried out in accordance with the provisional daily intake (PTDI) recommended by the FAO/WHO as well as hazard quotient and cancer risk standards based on the US Environmental Protection Agency. The variability of body weights and drinking water consumption scenarios are considered in exposure and risk assessment. Results shows that daily intake exceeds 2.1?g day-1 kg-1 BW for 2% of population, HQ level above unity for 20% , and can risk greater than 10-6 for 80%. These results implies that drinking water directly from groundwater will place many people at the risk of exposure and any efforts to supply safe drinking water is imperial for governing in order to protect the human health of inhabitants in Pingtung Plain.

    Background: Over the past 20 years, knowledge of the genome and its function has increased dramatically, but risk assessment methodologies using such knowledge have not advanced accordingly. Objective: This commentary describes a collaborative effort among several federal and state agencies to advance the next generation of risk assessment. The objective of the NexGen program is to begin to incorporate recent progress in molecular and systems biology into risk assessment practice. The ultimate success of this program will be based on the incorporation of new practices that facilitate faster, cheaper, and/or more accurate assessments of public health risks. Methods: We are developing prototype risk assessments that compare the results of traditional, data-rich risk assessments with insights gained from new types of molecular and systems biology data. In this manner, new approaches can be validated, traditional approaches improved, and the value of different types of new scientific information better understood. Discussion and Conclusions: We anticipate that these new approaches will have a variety of applications, such as assessment of new and existing chemicals in commerce and the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Additionally, results of the effort are likely to spur further research and test methods development. Full implementation of new approaches is likely to take 10–20 years. PMID:22875311

    2005-01-01

    Triggered by corporate scandals, there is increased oversight by governmental bodies and in part by the Sarbanes-Oxley Act of 2002. Corporations are developing corporate governance compliance initiatives to respond to the scrutiny of regulators, legislators, the general public and constituency groups such as investors. Due to state attorney general initiatives, new legislation and heightened oversight from the Internal Revenue Service, nonprofit entities are starting to share the media spotlight with their for-profit counterparts. These developments are changing nonprofit health care organizations as well as the traditional role of the risk manager. No longer is the risk manager focused solely on patients' welfare and safe passage through a complex delivery system. The risk manager must be aware of corporate practices within the organization that could allow the personal objectives of a few individuals to override the greater good of the community in which the nonprofit organization serves.

    OBJECTIVE To analyze the prevalence of individuals at risk of dependence and its associated factors. METHODS The study was based on data from the Catalan Health Survey, Spain conducted in 2010 and 2011. Logistic regression models from a random sample of 3,842 individuals aged ? 15 years were used to classify individuals according to the state of their personal autonomy. Predictive models were proposed to identify indicators that helped distinguish dependent individuals from those at risk of dependence. Variables on health status, social support, and lifestyles were considered. RESULTS We found that 18.6% of the population presented a risk of dependence, especially after age 65. Compared with this group, individuals who reported dependence (11.0%) had difficulties performing activities of daily living and had to receive support to perform them. Habits such as smoking, excessive alcohol consumption, and being sedentary were associated with a higher probability of dependence, particularly for women. CONCLUSIONS Difficulties in carrying out activities of daily living precede the onset of dependence. Preserving personal autonomy and function without receiving support appear to be a preventive factor. Adopting an active and healthy lifestyle helps reduce the risk of dependence. PMID:26018786

    Objective: Examining oral health and oral hygiene as predictors of subsequent one-year survival in the institutionalized elderly. Design: It was hypothesized that oral health would be related to mortality in an institutionalized geriatric population. A 12-month prospective study of 292 elderly residing in nine geriatric institutions in Granada, Spain, was thus carried out to evaluate the association between oral health and mortality. Independent samples, T-test, chi-square test and Cox regression analysis were used to analyze the data. Sixty-three participants died during the 12-month follow-up. Results: Mortality was increased in denture users (RR = 2.18, p= 0.007) and in people suffering severe cognitive impairment (RR = 2. 24, p= 0.003). One-year mortality was 50% in participants having both these characteristics. Conclusions: Oral hygiene was not significantly associated with mortality. Cognitive impairment and wearing dentures increased the risk of death. One-year mortality was 50% in cognitively impaired residents wearing dentures as opposed to 10% in patients without dentures and cognitive impairment. Key words:Oral health, mortality risk, institutionalised elderly. PMID:22322487

    This research found evidence of an association between occupational exposure to bioaerosols in composting plants and health outcome occurrence in exposed workers. An occupational exposure assessment in six composting plants was performed to better characterize personal exposure levels and evaluate associated health risk in workers. Sampling results showed large ranges of concentrations of dust, bacteria, molds, and endotoxin in ambient air and in personal samples, both when driving a front-end loader and when cleaning, monitoring, and performing maintenance tasks. Mean personal exposure levels were high at 100 to more than 10,000 times higher than outdoor background levels and fully consistent with occurrence of inflammatory and allergic respiratory outcomes among workers. Engineering control, personal protection, and education and training programs for employees, health, and safety officials, and occupational physicians are being developed and implemented.

    Consumers and patients want to be included in decisions regarding their own health and have an ethically justified claim on informed decisions. Therefore, sound information is required, but health information is often misleading and based on different interests. The risks of disease and the benefits of medical interventions tend to be overestimated, whereas harm is often underestimated. Evidence-based health information has to fulfil certain criteria, for instance, it should be evidence-based, independent, complete, true as well as understandable. The aim of a medical intervention has to be explained. The different therapeutic options including the option not to intervene have to be delineated. The probabilities for success, lack of success and unwanted side effects have to be communicated in a numerical and understandable manner. Patients have the right to reject medical interventions without any sanctions. PMID:26195924

  6. IMPACT OF FDA DRUG RISK COMMUNICATIONS ON HEALTH CARE UTILIZATION AND HEALTH BEHAVIORS: A SYSTEMATIC REVIEW

    Objective To review literature on the impact of FDA drug risk communications on medication utilization, health care services use, and health outcomes. Data Sources The authors searched MEDLINE and the Web of Science for manuscripts published between January 1990 and November 2010 that included terms related to drug utilization, the FDA, and advisories or warnings. We manually searched bibliographies and works citing selected articles and consulted with experts to guide study selection. Study Selection Studies were included if they involved an empirical analysis evaluating the impact of an FDA risk communication. Data Extraction We extracted the drug(s) analyzed, relevant FDA communication(s), data source, analytical method, and main outcome(s) assessed. Results Of the 1432 records screened, 49 studies were included. These studies covered sixteen medicines or therapeutic classes; one-third examined communications regarding antidepressants. Most used medical or pharmacy claims and few rigorously examined patient-provider communication, decision-making or risk perceptions. Advisories recommending increased clinical or laboratory monitoring generally led to decreased drug use, but only transient and modestly increased monitoring. Communications targeting specific subpopulations often spilled over to other groups. Repeated or sequential advisories tended to have larger but delayed effects and decreased incident more than prevalent use. Drug-specific warnings were associated with particularly large decreases in utilization, though the magnitude of substitution within therapeutic classes varied across clinical contexts. Conclusions While some FDA drug risk communications had immediate, strong impacts, many had either delayed or no impact on health care utilization or health behaviors. These data demonstrate the complexity of using risk communication to improve the quality and safety of prescription drug use, and suggest the importance of continued assessments of the effect of future advisories and label changes. Identifying factors that are associated with rapid and sustained responses to risk communications will be important for informing future risk communication efforts. PMID:22266704

    The Environmental Health activity for the Extended Duration Orbiter Medical Project (EDOMP) was formed to develop an overall strategy for safeguarding crew members from potential airborne hazards anticipated on missions of extended duration. These efforts were necessary because of major modifications to the air revitalization system of the U.S. Space Shuttle and an increased potential for environmental health risks associated with longer space flights. Degradation of air quality in the Shuttle during a space flight mission has the potential to affect the performance of the crew not only during piloting, landing, or egress, but also during space flight. It was anticipated that the risk of significant deterioration in air quality would increase with extended mission lengths and could result from: (1) a major chemical contamination incident, such as a thermodegradation event or toxic leak, (2) continual accumulation of volatile organic compounds to unacceptable levels, (3) excessive levels of airborne particles, (4) excessive levels of microorganisms, or (5) accumulation of airborne pathogens.

    This research has aimed to identify the perceptions of women apprentice welders about physical, chemical, biological, and physiological risk factors to which they are exposed and evaluate the identification of health disorders self-reported for women apprentice welders before and after implementation of a nursing socioenvironmental intervention. A quantitative study was performed with 27 women apprentice welders (first phase) and before and after an intervention with 18 women (second phase) in Southern Brazil in 2011. The data were analysed using SPSS 19.0. The participants identified the following risk types: physical (96.2%), chemical (96.2%), physiological (88.8%), and biological (62.9%). The results show a significant difference of the pre- and posttest averages for the musculoskeletal system and a posttest average increase for the integumentary, respiratory, and auditory system. A correlation of the women apprentices' ages and the identification of health disorders were made. It was understood that the perception of women apprentices regarding a particular set of occupational risks is essential for public health nursing to develop an effective risk communication as a positive tool for teaching and learning.

    Purpose Sudden cardiac death (SCD) is an important cause of mortality in the adult population. Height has been associated with cardiac hypertrophy and an increased risk of arrhythmias, but also with decreased risk of coronary heart disease, suggesting a complex association with SCD. Methods We examined the association of adult height with the risk of physician-adjudicated SCD in two large population-based cohorts: the Cardiovascular Health Study (CHS) and the Atherosclerosis Risk in Communities (ARIC) study. Results Over an average follow-up time of 11.7 years in CHS, there were 199 (3.6%) cases of SCD among 5,556 participants. In ARIC, over 12.6 years, there were 227 (1.5%) cases of SCD among 15,633 participants. In both cohorts, there was a trend towards decreased SCD with taller height. In fixed effects meta-analysis, the pooled hazard ratio per 10 cm of height was 0.84 (95%CI 0.73, 0.98, p=0.03). The association of increased height with lower risk of SCD was slightly attenuated after inclusion of risk factors associated with height, such as hypertension and left ventricular hypertrophy. The association appeared stronger among men than women in both cohorts. Conclusion In two population-based prospective cohorts of different ages, greater height was associated with lower risk of SCD.

  10. Using exposomics to assess cumulative risks and promote health.

    Under the exposome paradigm all nongenetic factors contributing to disease are considered to be 'environmental' including chemicals, drugs, infectious agents, and psychosocial stress. We can consider these collectively as environmental stressors. Exposomics is the comprehensive analysis of exposure to all environmental stressors and should yield a more thorough understanding of chronic disease development. We can operationalize exposomics by studying all the small molecules in the body and their influence on biological pathways that lead to impaired health. Here, we describe methods by which this may be achieved and discuss the application of exposomics to cumulative risk assessment in vulnerable populations. Since the goal of cumulative risk assessment is to analyze, characterize, and quantify the combined risks to health from exposures to multiple agents or stressors, it seems that exposomics is perfectly poised to advance this important area of environmental health science. We should therefore support development of tools for exposomic analysis and begin to engage impacted communities in participatory exposome research. A first step may be to apply exposomics to vulnerable populations already studied by more conventional cumulative risk approaches. We further propose that recent migrants, low socioeconomic groups with high environmental chemical exposures, and pregnant women should be high priority populations for study by exposomics. Moreover, exposomics allows us to study interactions between chronic stress and environmental chemicals that disrupt stress response pathways (i.e., 'stressogens'). Exploring the impact of early life exposures and maternal stress may be an interesting and accessible topic for investigation by exposomics using biobanked samples. Environ. Mol.

    The U.S. Environmental Protection Agency (EPA) is preparing, for the U.S. Congress, a report evaluating the need to regulate mercury (Hg) emissions from electric utilities. This study, to be completed in 1995, will have important health and economic implications. In support of these efforts, the U.S. Department of Energy, Office of Fossil Energy, sponsored a risk assessment project at Brookhaven National Laboratory (BNL) to evaluate methylmercury (MeHg) hazards independently. In the BNL study, health risks to adults resulting from Hg emissions from a hypothetical 1000 MW{sub e} coal-fired power plant were estimated using probabilistic risk assessment techniques. The approach draws on the extant knowledge in each of the important steps in the calculation chain from emissions to health effects. Estimated results at key points in the chain were compared with actual measurements to help validate the modeled estimates. Two cases were considered: the baseline case (no local impacts), and the impact case (maximum local power-plant impact). The BNL study showed that the effects of emissions of a single power plant may double the background exposures to MeHg resulting from consuming fish obtained from a localized area near the power plant. Many implicit and explicit sources of uncertainty exist in this analysis. Those that appear to be most in need of improvement include data on doses and responses for potentially sensitive subpopulations (e.g., fetal exposures). Rather than considering hypothetical situations, it would also be preferable to assess the risks associated with actual coal-fired power plants and the nearby sensitive water bodies and susceptible subpopulations. Finally, annual total Hg emissions from coal burning and from other anthropogenic sources are still uncertain; this makes it difficult to estimate the effects of U.S. coal burning on global Hg concentration levels, especially over the long term.

    2010-01-01

    Background Using the most effective methods and techniques for communicating risk to the public is critical. Understanding the impact that different types of risk communication have played in real and perceived public health risks can provide information about how messages, policies and programs can and should be communicated in order to be most effective. The purpose of this systematic review is to identify the effectiveness of communication strategies and factors that impact communication uptake related to environmental health risks. Methods A systematic review of English articles using multiple databases with appropriate search terms. Data sources also included grey literature. Key organization websites and key journals were hand searched for relevant articles. Consultation with experts took place to locate any additional references. Articles had to meet relevance criteria for study design [randomized controlled trials, clinical controlled trials, cohort analytic, cohort, any pre-post, interrupted time series, mixed methods or any qualitative studies), participants (those in community-living, non-clinical populations), interventions (including, but not limited to, any community-based methods or tools such as Internet, telephone, media-based interventions or any combination thereof), and outcomes (reported measurable outcomes such as awareness, knowledge or attitudinal or behavioural change). Articles were assessed for quality and data was extracted using standardized tools by two independent reviewers. Articles were given an overall assessment of strong, moderate or weak quality. Results There were no strong or moderate studies. Meta-analysis was not appropriate to the data. Data for 24 articles were analyzed and reported in a narrative format. The findings suggest that a multi-media approach is more effective than any single media approach. Similarly, printed material that offers a combination of information types (i.e., text and diagrams) is a more effective than just a single type, such as all text. Findings also suggest that factors influencing response to risk communications are impacted by personal risk perception, previous personal experience with risk, sources of information and trust in those sources. Conclusions No single method of message delivery is best. Risk communication strategies that incorporate the needs of the target audience(s) with a multi-faceted delivery method are most effective at reaching the audience. PMID:21040529

    Bisphenol A (BPA) is an endocrine disruptor for which health risk assessment has proven controversial. Conclusions regarding health risks of BPA vary between assessments from "there is no risk to any part of the population" to "there is risk to the entire population". We have carried out a literature study investigating what might be the scientific and/or policy-related reasons for these differences. Ten risk assessments for BPA were scrutinized and several factors were compared between assessments, including estimations of exposure levels, identification of critical study and NOAEL, assessment factors and significance attributed to reports of low-dose effects. Differences in conclusions were mainly influenced by the evaluation of low-dose effects and the uncertainties surrounding the significance of these data for health risk assessment. The results illustrate the impact of differences in risk assessment policy and expert judgment on the risk assessment process and highlight the importance of transparency in this process.

  14. Global climate changes, natural disasters, and travel health risks.

    2006-01-01

    Whether the result of cyclical atmospheric changes, anthropogenic activities, or combinations of both, authorities now agree that the earth is warming from a variety of climatic effects, including the cascading effects of greenhouse gas emissions to support human activities. To date, most reports of the public health outcomes of global warming have been anecdotal and retrospective in design and have focused on heat stroke deaths following heat waves, drowning deaths in floods and tsunamis, and mosquito-borne infectious disease outbreaks following tropical storms and cyclones. Accurate predictions of the true public health outcomes of global climate change are confounded by several effect modifiers including human acclimatization and adaptation, the contributions of natural climatic changes, and many conflicting atmospheric models of climate change. Nevertheless, temporal relationships between environmental factors and human health outcomes have been identified and may be used as criteria to judge the causality of associations between the human health outcomes of climate changes and climate-driven natural disasters. Travel medicine physicians are obligated to educate their patients about the known public health outcomes of climate changes, about the disease and injury risk factors their patients may face from climate-spawned natural disasters, and about the best preventive measures to reduce infectious diseases and injuries following natural disasters throughout the world.

    In most industrialized countries large numbers of workers are exposed to welding fumes. Although the general pattern of welders' health may not significantly differ from that of workers in other dusty industrial occupations which demonstrate elevated incidence of respiratory tract diseases with long latency periods, the extremely wide range of substances at potentially high concentrations produced by various welding technologies may give rise to undetected process-specific high-risk working conditions: ("hot spots"). The origin, prevalence and range of magnitude of such hot spots, especially for cancer of the respiratory tract, is discussed, with emphasis placed on the assessment of risk resulting from exposure to Cr(VI) and Ni accompanying the use of various technologies for the welding of stainless and high alloy steels. The wide variation of health effects found within the industry, however, indicates the need for a standard protocol for future epidemiological studies, as well as for the development of suitable methodologies for experimental risk assessment.

    Purpose The purpose of this article was to summarize scientific knowledge from an expert panel on reproductive health among adolescents with type 2 diabetes (T2D). Methods Using a mental model approach, a panel of experts—representing perspectives on diabetes, adolescents, preconception counseling, and reproductive health—was convened to discuss reproductive health issues for female adolescents with T2D. Results Several critical issues emerged. Compared with adolescents with type 1 diabetes, (1) adolescents with T2D may perceive their disease as less severe and have less experience managing it, putting them at risk for complications; (2) T2D is more prevalent among African Americans, who may be less trusting of the medical establishment; (3) T2D is associated with obesity, and it is often difficult to change one’s lifestyle within family environments practicing sedentary and dietary behaviors leading to obesity; (4) teens with T2D could be more fertile, because obesity is related to earlier puberty; (5) although obese teens with T2D have a higher risk of polycystic ovary syndrome, which is associated with infertility, treatment with metformin can increase fertility; and (6) women with type 2 diabetes are routinely transferred to insulin before or during pregnancy to allow more intensive management. Conclusions Findings from the expert panel provide compelling reasons to provide early, developmentally appropriate, culturally sensitive preconception counseling for teens with T2D. PMID:20944055

    2012-01-01

    The risks of genetically modified organisms (GMOs) are evaluated traditionally by combining hazard identification and exposure estimates to provide decision support for regulatory agencies. We question the utility of the classical risk paradigm and discuss its evolution in GMO risk assessment. First, we consider the problem of uncertainty, by comparing risk assessment for environmental toxins in the public health domain with genetically modified organisms in the environment; we use the specific comparison of an insecticide to a transgenic, insecticidal food crop. Next, we examine normal accident theory (NAT) as a heuristic to consider runaway effects of GMOs, such as negative community level consequences of gene flow from transgenic, insecticidal crops. These examples illustrate how risk assessments are made more complex and contentious by both their inherent uncertainty and the inevitability of failure beyond expectation in complex systems. We emphasize the value of conducting decision-support research, embracing uncertainty, increasing transparency, and building interdisciplinary institutions that can address the complex interactions between ecosystems and society. In particular, we argue against black boxing risk analysis, and for a program to educate policy makers about uncertainty and complexity, so that eventually, decision making is not the burden that falls upon scientists but is assumed by the public at large.

    Following more than a decade of scientific debate about the setting of a standard for 222Rn in drinking water, Congress established a timetable for the promulgation of a standard in the 1996 Amendments to the Safe Drinking Water Act. As a result of those Amendments, the EPA contracted with the National Academy of Sciences to undertake a risk assessment for exposure to radon in drinking water. In addition, the resulting committee was asked to address several other scientific issues including the national average ambient 222Rn concentration and the increment of 222Rn to the indoor- air concentration arising from the use of drinking water in a home. A new dosimetric analysis of the cancer risk to the stomach from ingestion was performed. The recently reported risk estimates developed by the BEIR VI Committee for inhalation of radon decay products were adopted. Because the 1996 Amendments permit states to develop programs in which mitigation of air- producing health-risk reductions equivalent to that which would be achieved by treating the drinking water, the scientific issues involved in such 'multimedia mitigation programs' were explored.

    This study evaluates the health risks in megacities in terms of mortality and morbidity due to air pollution. A new spreadsheet model, Risk of Mortality/Morbidity due to Air Pollution (Ri-MAP), is used to estimate the excess numbers of deaths and illnesses. By adopting the World Health Organization (WHO) guideline concentrations for the air pollutants SO 2, NO 2 and total suspended particles (TSP), concentration-response relationships and a population attributable-risk proportion concept are employed. Results suggest that some megacities like Los Angeles, New York, Osaka Kobe, Sao Paulo and Tokyo have very low excess cases in total mortality from these pollutants. In contrast, the approximate numbers of cases is highest in Karachi (15,000/yr) characterized by a very high concentration of total TSP (˜670 ?g m -3). Dhaka (7000/yr), Beijing (5500/yr), Karachi (5200/yr), Cairo (5000/yr) and Delhi (3500/yr) rank highest with cardiovascular mortality. The morbidity (hospital admissions) due to Chronic Obstructive Pulmonary Disease (COPD) follows the tendency of cardiovascular mortality. Dhaka and Karachi lead the rankings, having about 2100/yr excess cases, while Osaka-Kobe (˜20/yr) and Sao Paulo (˜50/yr) are at the low end of all megacities considered. Since air pollution is increasing in many megacities, and our database of measured pollutants is limited to the period up to 2000 and does not include all relevant components (e.g. O 3), these numbers should be interpreted as lower limits. South Asian megacities most urgently need improvement of air quality to prevent excess mortality and morbidity due to exceptionally high levels of air pollution. The risk estimates obtained from Ri-MAP present a realistic baseline evaluation for the consequences of ambient air pollution in comparison to simple air quality indices, and can be expanded and improved in parallel with the development of air pollution monitoring networks.

    This paper reviews the framework of regulatory and managerial devices that have evolved in response to the special dangers to the public posed by insolvency of health carriers. These devices include "prudential" measures designed to decrease the likelihood of insolvency, and measures to "protect enrollees" in the event that insolvency occurs nevertheless. It also reviews the current debate over how this framework should be adapted to new forms of risk-bearing entities, especially provider-sponsored networks engaged in direct contracting with purchasers of coverage. Parallels to solvency concerns in the banking industry are explored. PMID:9018940

    The term "Wind Turbine Syndrome" was coined in a recently self-published book, which hypothesized that a multitude of symptoms such as headache and dizziness resulted from wind turbines generating low frequency sound (LFS). The objective of this article is to provide a summary of the peer-reviewed literature on the research that has examined the relationship between human health effects and exposure to LFS and sound generated from the operation of wind turbines. At present, a specific health condition has not been documented in the peer-reviewed literature that has been classified as a disease caused by exposure to sound levels and frequencies generated by the operation of wind turbines. Communities are experiencing a heightened sense of annoyance and fear from the development and siting of wind turbine farms. High-quality research and effective risk communication can advance this course from one of panic to one of understanding and exemplification for other environmental advancements. PMID:23621051

    1996-07-17

    The first case of chronic beryllium disease (CBD) at the Rocky Flats Environmental Technology Site (Rocky Flats) was diagnosed in a machinist in 1984. Rocky Flats, located 16 miles northwest of Denver, Colorado, is part of the United States Department of Energy (DOE) nuclear weapons complex. Research and development operations using beryllium began at Rocky Flats in 1953, and beryllium production operations began in 1957. Exposures could have occurred during foundry operations, casting, shearing, rolling, cutting, welding, machining, sanding, polishing, assembly, and chemical analysis operations. The Beryllium Health Surveillance Program (BHSP) was established in June 1991 at Rocky Flats to provide health surveillance for beryllium exposed employees using the Lymphocyte Proliferation Test (LPT) to identify sensitized individuals. Of the 29 cases of CBD and 76 cases of beryllium sensitization identified since 1991, several cases appear to have had only minimal opportunistic exposures to beryllium, since they were employed in administrative functions rather than primary beryllium operations. In conjunction with other health surveillance programs, a questionnaire and interview are administered to obtain detailed work and health histories. These histories, along with other data, are utilized to estimate the extent of an individual's exposure. Additional surveillance is in progress to attempt to characterize the possible risks from intermittent or brief exposures to beryllium in the workplace. PMID:8711738

    Over the last dozen years, many national and international expert groups have considered specific improvements to risk assessment. Many of their stated recommendations are mutually supportive, but others appear conflicting, at least in an initial assessment. This review identifies areas of consensus and difference and recommends a practical, biology-centric course forward, which includes: (1) incorporating a clear problem formulation at the outset of the assessment with a level of complexity that is appropriate for informing the relevant risk management decision; (2) using toxicokinetics and toxicodynamic information to develop Chemical Specific Adjustment Factors (CSAF); (3) using mode of action (MOA) information and an understanding of the relevant biology as the key, central organizing principle for the risk assessment; (4) integrating MOA information into dose–response assessments using existing guidelines for non-cancer and cancer assessments; (5) using a tiered, iterative approach developed by the World Health Organization/International Programme on Chemical Safety (WHO/IPCS) as a scientifically robust, fit-for-purpose approach for risk assessment of combined exposures (chemical mixtures); and (6) applying all of this knowledge to enable interpretation of human biomonitoring data in a risk context. While scientifically based defaults will remain important and useful when data on CSAF or MOA to refine an assessment are absent or insufficient, assessments should always strive to use these data. The use of available 21st century knowledge of biological processes, clinical findings, chemical interactions, and dose–response at the molecular, cellular, organ and organism levels will minimize the need for extrapolation and reliance on default approaches.

  10. Health risk assessments of DEHP released from chemical protective gloves.

    PubMed

    2015-01-01

    The substance di-2-ethylhexyl phthalate (DEHP) is widely used as a plasticizer in chemical protective gloves to improve their flexibility and workability. However, it is possible that workers using protective gloves to handle various solvents may be exposed to DEHP leached by the solvents. Using an ASTM F739 permeation cell, it was found that BTEX solvents permeating through the glove samples dissolved DEHP from the gloves. Even without continuously contacting the permeant, DEHP was released from the contaminated glove samples during the desorption experiments. The DEHP leaching amounts were found to be inversely correlated to the permeability coefficients of BTEX in the glove samples. This result implied that the larger the amount of DEHP released from the glove samples, the higher the permeation resistance of gloves. Although chemical protective gloves provide adequate skin exposure protection to workers, the dermal exposure model developed herein indicates that leaching of DEHP from the glove samples may pose a potential health risk to the workers who handle BTEX. This study suggests that the selection of protective gloves should not only be concerned with the chemical resistance of the gloves but also the health risk associated with leaching of chemicals, such as DEHP, used in the manufacturing of the gloves.

    Produced water generated during the production of oil and gas can contain enhanced levels of radium. This naturally occurring radioactive material (NORM) is discharged into freshwater streams, estuarine, coastal and outer continental shelf waters. Large volumes of produced waters are discharged to coastal waters along the Gulf Coast of Louisiana. The Gulf of Mexico is an important producer of fish and shellfish, and there is concern that radium discharged to coastal Louisiana could contaminate fish and shellfish used by people for food, and present a significant increase in cancer risk. This paper describes a screening-level assessment of the potential cancer risks posed by radium discharged to coastal Louisiana in oil-field produced waters. This screening analysis was performed to determine if a more comprehensive and realistic assessment is necessary, and because of the conservative assumptions embedded in the analysis overestimates the risk associated with the discharge of radium in produced waters. Two isotopes of radium (Ra-226 and Ra-228) are the radionuclides of most concern in produced water in terms of potential human health effects.

  15. Bioethics and the Framing of Climate Change's Health Risks.

    PubMed

    Valles, Sean A

    2015-06-01

    Cheryl Cox MacPherson recently argued, in an article for this journal, that 'Climate Change is a Bioethics Problem'. This article elaborates on that position, particularly highlighting bioethicists' potential ability to help reframe the current climate change discourse to give more attention to its health risks. This reframing process is especially important because of the looming problem of climate change skepticism. Recent empirical evidence from science framing experiments indicates that the public reacts especially positively to climate change messages framed in public health terms, and bioethicists are particularly well positioned to contribute their expertise to the process of carefully developing and communicating such messages. Additionally, as climate framing research and practice continue, it will be important for bioethicists to contribute to the creation of that project's nascent ethical standards. The discourse surrounding antibiotic resistance is posited as an example that can lend insight into how communicating a public health-framed message, including the participation of bioethicists, can help to override public skepticism about the findings of politically contentious scientific fields.

  2. Perceived extrinsic mortality risk and reported effort in looking after health: testing a behavioral ecological prediction.

    PubMed

    2014-09-01

    Socioeconomic gradients in health behavior are pervasive and well documented. Yet, there is little consensus on their causes. Behavioral ecological theory predicts that, if people of lower socioeconomic position (SEP) perceive greater personal extrinsic mortality risk than those of higher SEP, they should disinvest in their future health. We surveyed North American adults for reported effort in looking after health, perceived extrinsic and intrinsic mortality risks, and measures of SEP. We examined the relationships between these variables and found that lower subjective SEP predicted lower reported health effort. Lower subjective SEP was also associated with higher perceived extrinsic mortality risk, which in turn predicted lower reported health effort. The effect of subjective SEP on reported health effort was completely mediated by perceived extrinsic mortality risk. Our findings indicate that perceived extrinsic mortality risk may be a key factor underlying SEP gradients in motivation to invest in future health. PMID:24990431

    Scientific and technological developments bring unprecedented stress to our environment. Society has to predict the results of potential health risks from technologically based actions that may have serious, far-reaching consequences. The potential for error in making such predictions or assessment is great and multiplies with the increasing size and complexity of the problem being studied. Because of this, the availability and use of reliable data is the key to any successful forecasting effort. Scientific research and development generate new data and information. Much of the scientific data being produced daily is stored in computers for subsequent analysis. This situation provides both an invaluable resource and an enormous challenge. With large amounts of government funds being devoted to health and environmental research programs and with maintenance of our living environment at stake, we must make maximum use of the resulting data to forecast and avert catastrophic effects. Along with the readily available. The most efficient means of obtaining the data necessary for assessing the health effects of chemicals is to utilize applications include the toxicology databases and information files developed at ORNL. To make most efficient use of the data/information that has already been prepared, attention and resources should be directed toward projects that meticulously evaluate the available data/information and create specialized peer-reviewed value-added databases. Such projects include the National Library of Medicine`s Hazardous Substances Data Bank, and the U.S. Air Force Installation Restoration Toxicology Guide. These and similar value-added toxicology databases were developed at ORNL and are being maintained and updated. These databases and supporting information files, as well as some data evaluation techniques are discussed in this paper with special focus on how they are used to assess potential health effects of environmental agents. 19 refs., 5 tabs.

  5. Human health risk assessment of 2-mercaptobenzothiazole in drinking water.

    2004-09-01

    2-Mercaptobenzothiazole (MBT) is used as a vulcanization accelerator in rubber products that come into contact with potable drinking water. When such products are evaluated for contact with potable water and submitted for ANSI/NSF Standard 61 certification, any chemical extracting from these products must be below an appropriate action level of exposure. As defined by Standard 61, a total allowable concentration (TAC) is the maximum concentration of a nonregulated contaminant allowed in a public drinking water supply, and the single product allowable concentration (SPAC) is 10% of the TAC. Currently, MBT has a TAC of 40 microg/L and a SPAC of 4 microg/L. A comprehensive health effects evaluation of MBT was performed to determine whether these action levels should be revised. Epidemiological investigations indicate that workers occupationally exposed to MBT have an increased risk of death from bladder cancer. Genotoxicity investigations in bacterial and mammalian test systems provide some evidence indicating that MBT has the potential to induce mutations and chromosomal aberrations. Toxicity studies in rats and mice chronically exposed to MBT identified increases in various tumours, such as adrenal gland tumours, pituitary gland tumours, liver tumours and renal pelvis tumours. The biological significance of most of these tumours is questionable due to a variety of factors, such as a lack of dose-response between tumour incidence and dose, and the effect of test article vehicle (corn oil) upon tumour rates. Potential human health effects of exposure to MBT can be predicted from an NTP 2-year cancer study in rats, as well as epidemiological investigations in occupationally exposed workers. A comprehensive review of the epidemiological and toxicological dataset for MBT indicates that the induction of renal pelvis transitional cell tumours is the most sensitive and relevant health effects endpoint upon which to base a revised TAC and SPAC. A multistage model was used to extrapolate to low-dose MBT exposures due to the genotoxicity and clastogenicity of MBT. A TAC of 600 microg/L was derived for MBT, and was based upon an LED10 of 157.681 mg/kg per day. A SPAC of 60 microg/L was derived by multiplying the revised TAC by 0.10, and rounding to one significant figure. These revised action levels are based upon the most sensitive health effects endpoint, as well as current cancer risk assessment methodology. PMID:15941012

    Objective Since 2003, the Chinese National Health and Family Planning Commission (formerly the Ministry of Health) has implemented changes to more effectively communicate risk during public health emergencies. In spite of ongoing improvements, provincial and sub-provincial leaders face barriers, such as established modes of operation, lack of training, shortage of trained risk communicators, and limited understanding and willingness of recipients to mitigate risks. Methods We assessed the current status of and barriers to risk communication knowledge and practice among public health practitioners in China. We designed the survey questionnaire to capture information related to the risk communication core capacities required by international health regulations and common risk communication principles. Results Our findings showed that risk communication training has successfully developed an awareness of risk communication principles and the ability to implement those principles in practice in China. Conclusions Future efforts should focus on areas such as a dedicated risk communication workforce, requirements that public health agencies develop a risk communication plan, and additional training for public health practitioners and their partners. It is critical that the infectious diseases prevention and control law be amended to grant provincial and local public health agencies more autonomy to release information. PMID:24785302

    Although Mexican American adolescents experience multiple risk factors in their daily lives, most research examines the influences of risk factors on adjustment independently, ignoring the additive and interactive effects of multiple risk factors. Guided by a person-centered perspective and utilizing latent profile analysis, this study identified Mexican American fifth graders’ (N = 749) risk profiles based on family, peer, and socio-cultural risk factors and examined the relationships of these risk profiles to mental health symptomatology in seventh grade. Results revealed three distinct profiles that differed quantitatively and qualitatively. Profiles were then linked to levels of mental health symptomatology, with youth in the highest risk profile displaying the most symptoms. Youth in two other risk profiles displayed lower levels. The findings suggest that Mexican American youth develop within distinct risk contexts that differ in their relationships to adjustment. Such findings inform prevention/intervention efforts aimed at reducing mental health problems in adolescence. PMID:23608782

    Daniels, C R; Paul, M; Rosofsky, R

    1990-01-01

    Potential exposure to occupational reproductive hazards raises complex questions regarding health and gender discrimination in the workplace. On the one hand, growing scientific evidence suggests that workplace exposures to either sex can cause a wide range of disorders ranging from infertility to adverse pregnancy outcomes. On the other hand, policies alleging to protect workers from reproductive risks have often reinforced gender inequalities in the workplace. This article sheds new light on this continuing debate through an examination of the policy insights suggested by a recent study of reproductive hazard policies in Massachusetts. In what ways do policies evidenced in this study reflect or differ from historical patterns of protectionism? The article presents a political-legal review of reproductive hazard policies in the workplace, then examines the policy implications of the Massachusetts study, and finally presents the prescriptions for change that are implied by both the historical and contemporary evidence.

    2015-04-01

    Risk assessments of contaminated land often involve the use of generic bioconcentration factors (BCFs), which express contaminant concentrations in edible plant parts as a function of the concentration in soil, in order to assess the risks associated with consumption of homegrown vegetables. This study aimed to quantify variability in BCFs and evaluate the implications of this variability for human exposure assessments, focusing on cadmium (Cd) and lead (Pb) in lettuce and potatoes sampled around 22 contaminated glassworks sites. In addition, risks associated with measured Cd and Pb concentrations in soil and vegetable samples were characterized and a probabilistic exposure assessment was conducted to estimate the likelihood of local residents exceeding tolerable daily intakes. The results show that concentrations in vegetables were only moderately elevated despite high concentrations in soil, and most samples complied with applicable foodstuff legislation. Still, the daily intake of Cd (but not Pb) was assessed to exceed toxicological thresholds for about a fifth of the study population. Bioconcentration factors were found to vary more than indicated by previous studies, but decreasing BCFs with increasing metal concentrations in the soil can explain why the calculated exposure is only moderately affected by the choice of BCF value when generic soil guideline values are exceeded and the risk may be unacceptable.

    Karabash city sprang up around the copper plant that uses local copper ore, which was composed of zinc, sulfur, barium, beryllium, arsenic, manganese, lead, antimony, chromium, cadmium, gallium, indium, scandium, thallium, germanium, osmium, and others. Centralized water supply for the city is organized from the lake Serebry and the flowage on the river B. Kialim. Part of the population uses water wells, voids and springs. In Serebry Lake and drinking groundwater there were found significant concentrations of nitrates, manganese, arsenic, cadmium, iron, lead barium, nickel, mercury and zinc. There are most exposed to toxic hazards from drinking water persons using water from Serebry aqueduct (hazard index for--children/ adults 2.75/1.1, respectively) and decentralized water supply sources (hazard index for children/adults--2.35/1.0). Maximal hazard coefficients were calculated for nitrates, arsenic and antimony. Among the systems mostly exposed to toxic effects are digestive, cardiovascular endocrine, nervous system and skin. Carcinogenic risk is caused by arsenic compounds, hexavalent chromium, and dichloroethane. Carcinogenic risk from water sources of decentralized water supply is 9,6 E-05, for water from Kialim reservoir--7,3 E-05. Maximum carcinogenic risk is associated with the water from the Serebry aqueduct, the risk reaches 2,17 E-04 and is characterized as unacceptable. PMID:25306690

    The use of ionizing radiation has been increased in recent years within medical applications. Nuclear Medicine Department offers both treatment and diagnosis of diseases using radioisotopes to controlled doses. Despite the great benefits to the patient, there is an inherent risk to workers which remains in contact with radiation sources for long periods. These personnel must be monitored to avoid deterministic effects. In this work, we retrospectively evaluated occupationally exposed personnel (OEP) to ionizing radiation in nuclear medicine during the last five years. We assessed both area and personal dosimetry of this department in a known Clinic in Sonora. Our results show an annual equivalent dose average of 4.49 ± 0.70 mSv in OEP without showing alarming changes in clinical parameters analyzed. These results allow us to conclude that health of OEP in nuclear medicine of this clinic has not been at risk during the evaluated period. However, we may suggest the use of individual profiles based on specific radiosensitivity markers.

    Emerging infectious diseases pose a growing threat to human populations. Many of the world's epidemic diseases (particularly those transmitted by intermediate hosts) are known to be highly sensitive to long-term changes in climate and short-term fluctuations in the weather. The application of environmental data to the study of disease offers the capability to demonstrate vector-environment relationships and potentially forecast the risk of disease outbreaks or epidemics. Accurate disease forecasting models would markedly improve epidemic prevention and control capabilities. This chapter examines the potential for epidemic forecasting and discusses the issues associated with the development of global networks for surveillance and prediction. Existing global systems for epidemic preparedness focus on disease surveillance using either expert knowledge or statistical modelling of disease activity and thresholds to identify times and areas of risk. Predictive health information systems would use monitored environmental variables, linked to a disease system, to be observed and provide prior information of outbreaks. The components and varieties of forecasting systems are discussed with selected examples, along with issues relating to further development.

Accurate disease forecasting models would markedly improve epidemic prevention and control capabilities. This chapter examines the potential for epidemic forecasting and discusses the issues associated with the development of global networks for surveillance and prediction. Existing global systems for epidemic preparedness focus on disease surveillance using either expert knowledge or statistical modelling of disease activity and thresholds to identify times and areas of risk. Predictive health information systems would use monitored environmental variables, linked to a disease system, to be observed and provide prior information of outbreaks. The components and varieties of forecasting systems are discussed with selected examples, along with issues relating to further development. PMID:10997211

    There are many health-risk behaviors that may elevate the risk of adolescents engaging in teenage dating violence. The purpose of this investigation was to examine the health-risk behaviors that are associated with a sample of female juvenile offenders to identify the extent to which those behaviors contribute to dating violence. The survey assessed respondents' health-risk behaviors prior to incarceration, their perceptions of quality of life, postincarceration expectations, psychosocial factors, and other social determinants. Results indicated youth exposure to dating violence, alcohol, drug, and risky sexual behaviors in the year prior to incarceration. These findings demonstrate the need to address teen dating violence with at-risk adolescents in addition to risky behaviors. PMID:26408099

  8. Mapping heatwave health risk at the community level for public health action

    PubMed Central

    2012-01-01

    Background Climate change poses unprecedented challenges, ranging from global and local policy challenges to personal and social action. Heat-related deaths are largely preventable, but interventions for the most vulnerable populations need improvement. Therefore, the prior identification of high risk areas at the community level is required to better inform planning and prevention. We aimed to demonstrate a simple and flexible conceptual framework relying upon satellite thermal data and other digital data with the goal of easily reproducing this framework in a variety of urban configurations. Results The study area encompasses Rennes, a medium-sized French city. A Landsat ETM?+?image (60 m resolution) acquired during a localized heatwave (June 2001) was used to estimate land surface temperature (LST) and derive a hazard index. A land-use regression model was performed to predict the LST. Vulnerability was assessed through census data describing four dimensions (socio-economic status, extreme age, population density and building obsolescence). Then, hazard and vulnerability indices were combined to deliver a heatwave health risk index. The LST patterns were quite heterogeneous, reflecting the land cover mosaic inside the city boundary, with hotspots of elevated temperature mainly observed in the city center. A spatial error regression model was highly predictive of the spatial variation in the LST (R2?=?0.87) and was parsimonious. Three land cover descriptors (NDVI, vegetation and water fractions) were negatively linked with the LST. A sensitivity analysis (based on an image acquired on July 2000) yielded similar results. Southern areas exhibited the most vulnerability, although some pockets of higher vulnerability were observed northeast and west of the city. The heatwave health risk map showed evidence of infra-city spatial clustering, with the highest risks observed in a north–south central band. Another sensitivity analysis gave a very high correlation between 2000 and 2001 risk indices (r?=?0.98, p?health risk index together with hazard and vulnerability indices to implement tailored programs because exposure to heat and vulnerability do not require the same prevention strategies.

    Objectives To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents. Methods Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors. Results Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors. Conclusions Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.

    The purpose of this work is to estimate off-site radiation doses and health risks (with uncertainties) associated with the release of radionuclides from the X-10 site. Following an initial screening analysis, the exposure pathways of interest included fish ingestion, drinking water ingestion, the ingestion of milk and meat, and external exposure from shoreline sediment. Four representative locations along the Clinch River, from the White Oak Creek Embayment to the city of Kingston, were chosen. The demography of the lower Clinch River supplied information dealing with land use that aided in the determination of sites on which to focus efforts. The locations that proved to be the most significant included Jones Island at Clinch River Mile (CRM) 20.5, Grassy Creek and K-25 (CRM 14), Kingston Steam Plant (CRM 3.5), and the city of Kingston (CRM 0). These areas of interest have historically been and are still primarily agricultural and residential areas. Reference individuals were determined with respect to the pathways involved. The primary radionuclides of interest released from the X-10 facility into the Clinch River via White Oak Creek were identified in the initial screening analysis as {sup 137}Cs, {sup 90}Sr, {sup 60}Co, {sup 106}Ru, {sup 144}Ce, {sup 131}I, {sup 95}Zr, and {sup 95}Nb. Of these radionuclides, {sup 137}Cs, {sup 60}Co, {sup 106}Ru, {sup 90}Sr, {sup 144}Ce, {sup 95}Zr, and {sup 95}Nb were evaluated for their contribution to the external exposure pathway. This study utilized an object-oriented modeling software package that provides an alternative to the spreadsheet, providing graphical influence diagrams to show qualitative structure of models, hierarchical models to organize complicated models into manageable modules, and intelligent arrays with the power to scale up simple models to handle large problems. The doses and risks estimated in this study are not significant enough to cause a detectable increase in health effects in the population. In most cases, the organ does are well below the limits of epidemiological detection (1 to 30 cSv) for radiation-induced health outcomes. Therefore, it is unlikely that exposure to radionuclides released from the X-10 site is responsible for an increased number of cancers to populations utilizing the Clinch River after 1944.

    Inhalable particulate matter (PM10) is a primary air pollutant closely related to public health, and an especially serious problem in urban areas. The urban heat island (UHI) effect has made the urban PM10 pollution situation more complex and severe. In this study, we established a health risk assessment system utilizing an epidemiological method taking the thermal environment effects into consideration. We utilized a remote sensing method to retrieve the PM10 concentration, UHI, Normalized Difference Vegetation Index (NDVI), and Normalized Difference Water Index (NDWI). With the correlation between difference vegetation index (DVI) and PM10 concentration, we utilized the established model between PM10 and thermal environmental indicators to evaluate the PM10 health risks based on the epidemiological study. Additionally, with the regulation of UHI, NDVI and NDWI, we aimed at regulating the PM10 health risks and thermal environment simultaneously. This study attempted to accomplish concurrent thermal environment regulation and elimination of PM10 health risks through control of UHI intensity. The results indicate that urban Beijing has a higher PM10 health risk than rural areas; PM10 health risk based on the thermal environment is 1.145, which is similar to the health risk calculated (1.144) from the PM10 concentration inversion; according to the regulation results, regulation of UHI and NDVI is effective and helpful for mitigation of PM10 health risk in functional zones.

    The present survey was designed to investigate the perception of health risks among college students in China. The data are the responses of a sample of 3,069 college students at one university to surveys that include measures of several dimensions of public judgments about fifteen specific hazards. Chinese college students conveyed their concerns as falling into three broad categories: Environmental (e.g., global warming, natural catastrophes, the ozone hole, air pollution, chemical pollution, pesticides in food), Technological (e.g., nuclear power stations, thermal power, genetically modified food, medical X-rays), and Social (cigarette smoking, drinking alcohol, overtime study or work, mental stress, motor vehicle accidents). The data were collected with a self-report questionnaire. Descriptive statistics were used to illustrate the levels of perceived risk according to the percent of “high risk” responses as well as the mean response values. Generally, the hazards that were perceived as posing the greatest health risk were those belonging to the social health risks; items related to technology risks received the lowest percentage of “high health risk” rankings. Traditional environmental risks such as natural catastrophes, pollution issues (chemical pollution, air pollution), and pesticides in food were ranked as being relatively high risks. The respondents were less concerned about new emerging issues and long-term environmental risks (global warming). In this survey, motor vehicle accidents were considered to be a “high health risk” by the greatest percentage of respondents. Generally speaking, the female respondents’ degree of recognition of health risks is higher than that of male respondents. Only for the item of smoking was the male respondents’ degree higher than that of females. There is also a geographic imbalance in the health risk perceptions. The degree of recognition of health risks from respondents in municipalities is generally lower than that of respondents from other areas except for items such as natural disasters, smoking, medical X-rays, and mental stress, which are exceptions.

    This research study examined the behavioral lifestyle patterns and health status of at-risk Latino college students for future diabetes onset in relation to their age, gender, and acculturation status. Participants were 156 Latino (34% male and 66% female) university students who had a first and/or second degree relative afflicted with diabetes. Findings indicated that Latino students exhibit similar lifestyle patterns in terms of dietary intake, physical activity, and drinking and smoking behaviors observed in the general and college population that have been linked to obesity—a particularly problematic risk factor among those who already have a genetic predisposition for diabetes. The reported findings are of importance for the development of culturally-relevant treatment interventions targeting young Latinos in college. PMID:26566366

    OBJECTIVE To analyze the relationships between sexual behavior and risk factors to physical and mental health in adolescents. METHODS Study of 3,195 pupils aged 15 to 19 in secondary education, in public and private schools in 10 state capitals in Brazil between 2007 and 2008. Multi-stage (schools and pupils) cluster sampling was used in each city and public and private educational network. All of the students selected completed a questionnaire on the following items: socioeconomic and demographic data; sexual behavior; having sex with those of the same sex, the opposite sex, or both; alcohol and cannabis use; using condoms; traumatic sexual experiences as a child or adolescent; suicidal thoughts. The analysis included describing frequencies, Chi-square test, analysis of multiple and cluster correspondence. Responses to an open ended question in which the adolescent expressed general comments about themselves and their lives were qualitatively analyzed using content analysis. RESULTS Around 3.0% of adolescents reported homosexual or bisexual behavior, with no difference according to sex, age, skin color, social status family structure or educational network. Adolescents with homosexual/bisexual sexual behavior, compared to their heterosexual peers, reported: (p < 0.05): getting drunk (18.7% and 10.5%, respectively), frequent cannabis use (6.1% and 2.1%, respectively), suicidal thoughts (42.5% and 18.7%, respectively), and having been the victim of sexual violence (11.7% and 1.5%; respectively). Adolescents with homosexual/bisexual sexual behavior reported that they used condoms less frequently (74.2%) than their heterosexual peers (48.6%, p < 0.001). In the correspondence analysis, three groups were found, one composed of adolescents with homosexual/bisexual behavior and experiencing risk factors; suffering sexual violence, never using a condom, suicidal thoughts, frequent cannabis use; another composed of occasional cannabis and condom users, who got drunk frequently, and adolescents with heterosexual behavior and none of the risk factors investigated. More of the risk factors were found in adolescents with homosexual/bisexual behavior compared with those with heterosexual behavior. Adolescents with homosexual/bisexual sexual behavior were more likely to talk about their positive personal experiences and negative relationship experiences that their heterosexual peers, but spoke less about religion. CONCLUSIONS Not only should this issue be studied in more detail, but preventative actions aimed at adolescents with homosexual/bisexual behavior should be widened. PMID:24789636

    The risk to human health from fragments of depleted uranium (DU) at Jefferson Proving Ground (JPG) was estimated using two types of ecosystem pathway models. A steady-state, model of the JPG area was developed to examine the effects of DU in soils, water, and vegetation on deer that were hunted and consumed by humans. The RESRAD code was also used to estimate the effects of farming the impact area and consuming the products derived from the farm. The steady-state model showed that minimal doses to humans are expected from consumption of deer that inhabit the impact area. Median values for doses to humans range from about 1 mrem ({plus_minus}2.4) to 0.04 mrem ({plus_minus}0.13) and translate to less than 1 {times} 10{sup {minus}6} detriments (excess cancers) in the population. Monte Carlo simulation of the steady-state model was used to derive the probability distributions from which the median values were drawn. Sensitivity analyses of the steady-state model showed that the amount of DU in airborne dust and, therefore, the amount of DU on the vegetation surface, controlled the amount of DU ingested by deer and by humans. Human doses from the RESRAD estimates ranged from less than 1 mrem/y to about 6.5 mrem/y in a hunting scenario and subsistence fanning scenario, respectively. The human doses exceeded the 100 mrem/y dose limit when drinking water for the farming scenario was obtained from the on-site aquifer that was presumably contaminated with DU. The two farming scenarios were unrealistic land uses because the additional risk to humans due to unexploded ordnance in the impact area was not figured into the risk estimate. The doses estimated with RESRAD translated to less than 1 {times} 10{sup {minus}6} detriments to about 1 {times} 10{sup {minus}3} detriments. The higher risks were associated only with the farming scenario in which drinking water was obtained on-site.

    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, there are assumptions that while reasonable cannot be proven, for example, the validity of extrapolating observed risk from much higher exposures to lower exposures, estimates of individual exposure, and that there is no threshold for asbestos to cause cancer.?CONCLUSIONS—The author is unaware of a similar study on long term health risks in a community exposed to asbestos in a fire. It is concluded that, using methods that do not underestimate risk, risk is undetectably small. Practical lessons from this methodology and approach to health risk assessment are discussed.???Keywords: asbestos; environmental pollutants; mesothelioma; health risk assessment; lung cancer PMID:11707487

    An underlying premise of the Affordable Care Act provisions that encourage employers to adopt health promotion programs is an association between workers' modifiable health risks and increased health care costs. Employers, consultants, and vendors have cited risk-cost estimates developed in the 1990s and wondered whether they still hold true. Examining ten of these common health risk factors in a working population, we found that similar relationships between such risks and total medical costs documented in a widely cited study published in 1998 still hold. Based on our sample of 92,486 employees at seven organizations over an average of three years, $82,072,456, or 22.4 percent, of the $366,373,301 spent annually by the seven employers and their employees in the study was attributed to the ten risk factors studied. This amount was similar to almost a quarter of spending linked to risk factors (24.9 percent) in the 1998 study. High risk for depression remained most strongly associated with increased per capita annual medical spending (48 percent, or $2,184, higher). High blood glucose, high blood pressure, and obesity were strongly related to increased health care costs (31.8 percent, 31.6 percent, and 27.4 percent higher, respectively), as were tobacco use, physical inactivity, and high stress. These findings indicate ongoing opportunities for well-designed and properly targeted employer-sponsored health promotion programs to produce substantial savings. PMID:23129678

    Background Investigators across many fields often struggle with how best to capture an individual’s overall health status, with options including both subjective and objective measures. With the increasing availability of “big data,” researchers can now take advantage of novel metrics of health status. These predictive algorithms were initially developed to forecast and manage expenditures, yet they represent an underutilized tool that could contribute significantly to health research. In this paper, we describe the properties and possible applications of one such “health risk score,” the DxCG Intelligence tool. Methods We link claims and administrative datasets on a cohort of U.S. workers during the period 1996–2011 (N = 14,161). We examine the risk score’s association with incident diagnoses of five disease conditions, and we link employee data with the National Death Index to characterize its relationship with mortality. We review prior studies documenting the risk score’s association with other health and non-health outcomes, including healthcare utilization, early retirement, and occupational injury. Results and Conclusions We find that the risk score is associated with outcomes across a variety of health and non-health domains. These examples demonstrate the broad applicability of this tool in multiple fields of research and illustrate its utility as a measure of overall health status for epidemiologists and other health researchers.

    Background Health behaviours, important factors in cardiovascular disease, are increasingly a focus of prevention. We appraised whether stroke risk can be accurately assessed using self-reported information focused on health behaviours. Methods Behavioural, sociodemographic and other risk factors were assessed in a population-based survey of 82 259 Ontarians who were followed for a median of 8.6 years (688 000 person-years follow-up) starting in 2001. Predictive algorithms for 5-year incident stroke resulting in hospitalization were created and then validated in a similar 2007 survey of 28 605 respondents (median 4.2 years follow-up). Results We observed 3 236 incident stroke events (1 551 resulting in hospitalization; 1 685 in the community setting without hospital admission). The final algorithms were discriminating (C-stat: 0.85, men; 0.87, women) and well-calibrated (in 65 of 67 subgroups for men; 61 of 65 for women). An index was developed to summarize cumulative relative risk of incident stroke from health behaviours and stress. For men, each point on the index corresponded to a 12% relative risk increase (180% risk difference, lowest (0) to highest (9) scores). For women, each point corresponded to a 14% relative risk increase (340% difference, lowest (0) to highest (11) scores). Algorithms for secondary stroke outcomes (stroke resulting in death; classified as ischemic; excluding transient ischemic attack; and in the community setting) had similar health behaviour risk hazards. Conclusion Incident stroke can be accurately predicted using self-reported information focused on health behaviours. Risk assessment can be performed with population health surveys to support population health planning or outside of clinical settings to support patient-focused prevention. PMID:26637172

    The development of industries in rural areas can aggravate the arsenic (As) contamination of the local environment, which may pose unacceptable health risks to the local residents. This paper estimated the health risk posed by inorganic As (iAs) to residents via ingestion of soil, skin contact with soil and consumption of foodstuffs in a typical rural- industrial developed town in southern Jiangsu, China. The average concentrations of total As in soil, rice, fish, shrimp and crab, pork and eggs, vegetables and fruits were detected to be 10.367, 0.104mg/kg dw (dry weight), 0.050, 0.415, 0.011, 0.013 and 0.017mg/kg fw (fresh weight), respectively. All of these values are below the maximum allowable concentration in food and soil in China. The deterministic estimation results showed that the hazard quotient (HQ) and excess lifetime cancer risk (R) were 1.28 (0.78-2.31) and 2.38×10(-4) (2.71×10(-5)-5.09×10(-4)) for all age groups, respectively. Males in the age range of 2-29 years and females in the age range of 2-13 years and 18-29 years exhibited non-carcinogenic risk (HQ>1). Carcinogenic risk exceeded the acceptable level of 1×10(-)(5) for both genders at all ages. Furthermore, this risk rose with age. The probabilistic estimation results showed that about 28% of residents had non-carcinogenic risk due to over ingestion of iAs. The R value of 90% of residents was greater than 10(-)(5). The sensitivity analysis indicated that the cancer slope factor (SF), the ingestion rates of rice and the iAs concentration in rice were the most relevant variables affecting the assessment outcome. Based on these results, it is recommended that residents reduce their consumption of rice, though it should be noted that the assessment outcome has uncertainty due to estimating iAs from foodstuffs and not considering the bioaccessibility of iAs in foodstuffs. Nevertheless, measures like reducing industrial As emissions, forbidding the use of pesticides, fertilizers and sludge which contain As and optimizing water management in rice paddy fields should be taken to mitigate the risks.

  12. Exploration of health risks related to air pollution and temperature in three Latin American cities

    NASA Astrophysics Data System (ADS)

    Romero-Lankao, P.; Borbor Cordova, M.; Qin, H.

    2013-12-01

    We explore whether the health risks related to air pollution and temperature extremes are spatially and socioeconomically differentiated within three Latin American cities: Bogota, Colombia, Mexico City, Mexico, and Santiago, Chile. Based on a theoretical review of three relevant approaches to risk analysis (risk society, environmental justice, and urban vulnerability as impact), we hypothesize that health risks from exposure to air pollution and temperature in these cities do not necessarily depend on socio-economic inequalities. To test this hypothesis, we gathered, validated, and analyzed temperature, air pollution, mortality and socioeconomic vulnerability data from the three study cities. Our results show the association between air pollution levels and socioeconomic vulnerabilities did not always correlate within the study cities. Furthermore, the spatial differences in socioeconomic vulnerabilities within cities do not necessarily correspond with the spatial distribution of health impacts. The present study improves our understanding of the multifaceted nature of health risks and vulnerabilities associated with global environmental change. The findings suggest that health risks from atmospheric conditions and pollutants exist without boundaries or social distinctions, even exhibiting characteristics of a boomerang effect (i.e., affecting rich and poor alike) on a smaller scale such as areas within urban regions. We used human mortality, a severe impact, to measure health risks from air pollution and extreme temperatures. Public health data of better quality (e.g., morbidity, hospital visits) are needed for future research to advance our understanding of the nature of health risks related to climate hazards.

    2014-10-01

    The human and financial costs of disasters are vast. In 2011, disasters were estimated to have cost $378 billion worldwide; disasters have affected 64% of the world's population since 1992. Consequently, disaster risk reduction strategies have become increasingly prominent on national and international policy agendas. However, the function of health in disaster risk reduction strategies often has been restricted to emergency response. To mitigate the effect of disasters on social and health development goals (such as risk reduction Millennium Development Goals) and increase resilience among at-risk populations, disaster strategies should assign the health sector a more all-encompassing, proactive role. We discuss proposed methods and concepts for mainstreaming health in disaster risk reduction and consider barriers faced by the health sector in this field. PMID:25122022

    The report was written to assist in the evaluation and interpretation of the human health risks associated with chemical contaminate levels in seafood. High concentrations of toxic chemicals have been found in sediments and marine organisms in parts of Puget Sound. Since heavy consumption of contaminated seafood may pose a substantial human health risk, it's important that assessments of the risk associated with seafood consumption be conducted in a consistent, acceptable manner. The report provides an overview of risk assessment, and describes hazard identification, dose-response assessment, exposure assessment and risk characterization. Guidance is provided on presentation and interpretation of results.

  3. Health-risk based approach to setting drinking water standards for long-term space missions

    1992-01-01

    In order to develop plausible and appropriate drinking water contaminant standards for longer-term NASA space missions, such as those planned for the Space Exploration Initiative, a human health risk characterization was performed using toxicological and exposure values typical of space operations and crew. This risk characterization showed that the greatest acute waterborne health concern was from microbial infection leading to incapacitating gastrointestinal illness. Ingestion exposure pathways for toxic materials yielded de minimus acute health risks unlikely to affect SEI space missions. Risks of chronic health problems were within acceptable public health limits. Our analysis indicates that current Space Station Freedom maximum contamination levels may be unnecessarily strict. We propose alternative environmental contaminant values consistent with both acceptable short and long-term crew health safety.

  4. A macro environmental risk assessment methodology for establishing priorities among risks to human health and the environment in the Philippines

    A macro environmental risk assessment (ERA) methodology was developed for the Philippine Department of Environment and Natural Resources (DENR) as part of the US Agency for International Development Industrial Environmental Management Project. The DENR allocates its limited resources to mitigate those environmental problems that pose the greatest threat to human health and the environment. The National Regional Industry Prioritization Strategy (NRIPS) methodology was developed as a risk assessment tool to establish a national ranking of industrial facilities. The ranking establishes regional and national priorities, based on risk factors, that DENR can use to determine the most effective allocation of its limited resources. NRIPS is a systematic framework that examines the potential risk to human health and the environment from hazardous substances released from a facility, and, in doing so, generates a relative numerical score that represents that risk. More than 3,300 facilities throughout the Philippines were evaluated successfully with the NRIPS.

  5. [Health risks in different living circumstances of mothers. Analyses based on a population study].

    PubMed

    Sperlich, Stefanie

    2014-12-01

    The objective of this study was to determine the living circumstances ('Lebenslagen') in mothers which are associated with elevated health risks. Data were derived from a cross-sectional population based sample of German women (n?=?3129) with underage children. By means of a two-step cluster analysis ten different maternal living circumstances were assessed which proved to be distinct with respect to indicators of socioeconomic position, employment status and family-related factors. Out of the ten living circumstances, one could be attributed to higher socioeconomic status (SES), while five were assigned to a middle SES and four to a lower SES. In line with previous findings, mothers with a high SES predominantly showed the best health while mothers with a low SES tended to be at higher health risk with respect to subjective health, mental health (anxiety and depression), obesity and smoking. However, there were important health differences between the different living circumstances within the middle and lower SES. In addition, varying health risks were found among different living circumstances of single mothers, pointing to the significance of family and job-related living conditions in establishing health risks. With this exploratory analysis strategy small-scale living conditions could be detected which were associated with specific health risks. This approach seemed particularly suitable to provide a more precise definition of target groups for health promotion. The findings encourage a more exrensive application of the concept of living conditions in medical sociology research as well as health monitoring. PMID:25355424

  6. Health benefits and risk associated with adopting a vegetarian diet.

    2014-01-01

    A vegetarian diet may be adopted for various reasons that can include ecological, economic, religious, ethical and health considerations. In the latter case they arise from the desire to lose weight, in tackling obesity, improving physical fitness and/or in reducing the risk of acquiring certain diseases. It has been shown that properly applied vegetarian diet is the most effective way of reducing body mass (expressed as BMI), improving the plasma lipid profile and in decreasing the incidence of high arterial blood pressure, cardiovascular disease, stroke, metabolic syndrome and arteriosclerosis. In addition, improved insulin sensitivity together with lower rates of diabetes and cancer has been observed. Some studies have however found that a vegetarian diet may result in changes adversely affecting the body. These could include; hyperhomocysteinaemia, protein deficiency, anaemia, decreased creatinine content in muscles and menstrual disruption in women who undertake increased physical activity. Some of these changes may decrease the ability for performing activities that require physical effort. Nevertheless, on balance it can be reasonably concluded that the beneficial effects of a vegetarian diet significantly, by far, outweigh the adverse ones. It should also be noted that the term 'vegetarian diet' is not always clearly defined in the literature and it may include many dietary variations. PMID:24964573

    2007-04-01

    This investigation assesses the feasibility of calculating and visualizing health risk estimates from exposure to groundwater contaminated with arsenic (As) using data from national geochemical databases. The potential health risk associated with As-contaminated groundwater was assessed based on an elaboration of existing geochemical data in accordance with accepted methodological procedures established for human health risk assessment (U.S. Environmental Protection Agency methodology). A screening analysis approach was used for estimating the contribution of As to the total chronic health risk from exposure to groundwater contaminated with potentially toxic elements, including As, Ba, Cd, Cu, Hg, Pb, Sb, Se and Zn, and the results indicate that As contributes significantly (>50%) to this total health chronic risk in about 10% of Slovak territory. Based on the calculation of the potential risk level by exposure modelling, increased chronic as well as carcinogenic risk levels (medium to high) were documented in approximately 0.2 and 11% of the total Slovak area, respectively. The areas characterized by high health risk levels are mainly those geogenically contaminated. High and very high carcinogenic risk was determined in 34 of 79 districts and in 528 of 2924 municipalities. PMID:17256097

    Climate change is already taking a toll on human health, a toll that is likely to increase in coming decades. The relationship between risk perceptions and vulnerability to climate change's health threats has received little attention, even though an understanding of the dynamics of adaptation among particularly susceptible populations is becoming increasingly important. We demonstrate that some people whose health will suffer the greatest harms from climate change-due to social vulnerability, health susceptibility, and exposure to hazards-already feel they are at risk. In a 2013 survey we measured Maryland residents' climate beliefs, health risk perceptions, and household social vulnerability characteristics, including medical conditions (n = 2126). We paired survey responses with secondary data sources for residence in a floodplain and/or urban heat island to predict perceptions of personal and household climate health risk. General health risk perceptions, political ideology, and climate beliefs are the strongest predictors. Yet, people in households with the following characteristics also see themselves at higher risk: members with one or more medical conditions or disabilities; low income; racial/ethnic minorities; and residence in a floodplain. In light of these results, climate health communication among vulnerable populations should emphasize protective actions instead of risk messages. PMID:26690184

  10. Proposal of a risk-factor-based analytical approach for integrating occupational health and safety into project risk evaluation.

    2012-09-01

    Excluding occupational health and safety (OHS) from project management is no longer acceptable. Numerous industrial accidents have exposed the ineffectiveness of conventional risk evaluation methods as well as negligence of risk factors having major impact on the health and safety of workers and nearby residents. Lack of reliable and complete evaluations from the beginning of a project generates bad decisions that could end up threatening the very existence of an organization. This article supports a systematic approach to the evaluation of OHS risks and proposes a new procedure based on the number of risk factors identified and their relative significance. A new concept called risk factor concentration along with weighting of risk factor categories as contributors to undesirable events are used in the analytical hierarchy process multi-criteria comparison model with Expert Choice(©) software. A case study is used to illustrate the various steps of the risk evaluation approach and the quick and simple integration of OHS at an early stage of a project. The approach allows continual reassessment of criteria over the course of the project or when new data are acquired. It was thus possible to differentiate the OHS risks from the risk of drop in quality in the case of the factory expansion project. PMID:22664685

    Unexpected medical care spending imposes considerable financial risk on developing country households. Based on managed care models of health insurance in wealthy countries, Colombia’s Régimen Subsidiado is a publicly financed insurance program targeted to the poor, aiming both to provide risk protection and to promote allocative efficiency in the use of medical care. Using a “fuzzy” regression discontinuity design, we find that the program has shielded the poor from some financial risk while increasing the use of traditionally under-utilized preventive services – with measurable health gains.

    OBJECTIVES. This study reports an efficacy trial of four work-site health promotion programs. It was predicted that strategies making use of behavioral counseling would produce a greater reduction in cardiovascular disease risk factors than screening and educational strategies. METHODS. Twenty-eight work sites were randomly allocated to a health risk assessment, risk factor education, behavioral counseling, or behavioral counseling plus incentives intervention. Participants were assessed before the intervention and at 3, 6, and 12 months. RESULTS. Compared with the average of the health risk assessment and risk factor education conditions, there were significantly higher validated continuous smoking cessation rates and smaller increases in body mass index and estimated percentage of body fat in the two behavioral counseling conditions. The behavioral counseling condition was associated with a greater reduction in mean blood pressure than was the behavioral counseling plus incentives condition. On average among all groups, there was a short-term increase in aerobic capacity followed by a return to baseline levels. CONCLUSIONS. Work-site interventions that use behavioral approaches can produce lasting changes in some cardiovascular risk factors and, if implemented routinely, can have a significant public health impact.

  18. Where Lies the Risk? An Ecological Approach to Understanding Child Mental Health Risk and Vulnerabilities in Sub-Saharan Africa

    PubMed Central

    2014-01-01

    Efforts at improving child-health and development initiatives in sub-Saharan Africa had focused on the physical health of children due to the neglect of child and adolescent mental health (CAMH) policy initiatives. A thorough and broad-based understanding of the prevalent child mental-health risk and vulnerability factors is needed to successfully articulate CAMH policies. In this discourse, we present a narrative on the child mental-health risk and vulnerability factors in sub-Saharan Africa. Through an ecological point of view, we identified widespread family poverty, poor availability and uptake of childcare resources, inadequate community and institutional childcare systems, and inadequate framework for social protection for vulnerable children as among the risk and vulnerability factors for CAMH in the region. Others are poor workplace policy/practice that does not support work-family life balance, poor legislative framework for child protection, and some harmful traditional practices. We conclude that an ecological approach shows that child mental-health risks are diverse and cut across different layers of the care environment. The approach also provides a broad and holistic template from which appropriate CAMH policy direction in sub-Saharan Africa can be understood. PMID:24834431

  19. Why income inequality indexes do not apply to health risks.

    PubMed

    Cox, Louis Anthony

    2012-02-01

    Several recent papers have sought to apply inequality measures from economics, such as the Atkinson Index (AI) for inequality of income distributions, to compare the risk inequality of different mortality risk distributions in an effort to help promote efficiency and environmental justice in pollution-reducing interventions. Closer analysis suggests that such applications are neither logically coherent nor necessarily ethically desirable. Risk inequality comparisons should be based on axioms that apply to probabilistic risks, and should consider the multidimensional and time-varying nature of individual and community risks in order to increase efficiency and justice over time and generations. In light of the limitations of the AI applied to mortality risk distributions, it has not been demonstrated to have ethical or practical value in helping policymakers to identify air pollution management interventions that reduce (or minimize) risk and risk inequity.

    Background Hospital risk stratification models using electronic health records (EHRs) often use age and comorbid health burden. Our primary aim was to determine if quality of life or health behaviors captured in an EHR-linked biobank can predict future risk of hospitalization. Methods Participants in the Mayo Clinic Biobank completed self-administered questionnaires at enrollment that included quality of life and health behaviors. Participants enrolled as of December 31, 2010 were followed for one year to ascertain hospitalization. Data on comorbidities and hospitalization were derived from the Mayo Clinic EHR. Hazard ratios (HR) and 95% confidence interval (CI) were used, adjusted for age and sex. We used gradient boosting machines models to integrate multiple factors. Different models were compared using C-statistic. Results Of the 8,927 eligible Mayo Clinic Biobank participants, 834 (9.3%) were hospitalized. Self-perceived health status and alcohol use had the strongest associations with risk of hospitalization. Compared to participants with excellent self-perceived health, those reporting poor/fair health had higher risk of hospitalization (HR =3.66, 95% CI 2.74–4.88). Alcohol use was inversely associated with hospitalization (HR =0.57 95% CI 0.45–0.72). The gradient boosting machines model estimated self-perceived health as the most influential factor (relative influence =16%). The predictive ability of the model based on comorbidities was slightly higher than the one based on the self-perceived health (C-statistic =0.67 vs 0.65). Conclusion This study demonstrates that self-perceived health may be an important piece of information to add to the EHR. It may be another method to determine hospitalization risk. PMID:26316799

    Health information exchange (HIE) is a significant component of healthcare transformation strategies at both the state and national levels. HIE is expected to improve care coordination, and advance public health, but implementation is massively complex and involves significant risk. In New York, three regional health information organizations (RHIOs) implemented an HIE use case for public health reporting by demonstrating capability to deliver accurate responses to electronic queries via a set of services called the Universal Public Health Node. We investigated process and outcomes of the implementation with a comparative case study. Qualitative analysis was structured around a decision and risk matrix. Although each RHIO had a unique operational model, two common factors influenced risk management and implementation success: leadership capable of agile decision-making and commitment to a strong organizational vision. While all three RHIOs achieved certification for the public health reporting, only one has elected to deploy a production version. PMID:23975626

    There is a growing awareness and concern in contemporary societies about potential health impacts of environmental contaminants on children. Mothers are traditionally more involved than other family members in managing family health and household decisions and thus targeted by public health campaigns to minimise risks. However little is known about how new mothers perceive and experience environmental health risks to their children. In 2010, we undertook a parallel case study using qualitative, in-depth interviews with new mothers and focus groups with public health key informants in two Public Health Units in Ontario Province, Canada. We found that the concern about environmental hazards among participants ranged from having no concerns to actively incorporating prevention into daily life. Overall, there was a common perception among participants that many risks, particularly in the indoor environment, were controllable and therefore of little concern. But environmental risks that originate outside the home were viewed as less controllable and more threatening. In response to such threats, mothers invoked coping strategies such as relying on the capacity of children's bodies to adapt. Regardless of the strategies adopted, actions (or inactions) were contingent upon active information seeking. We also found an optimistic bias in which new mothers reported that other children were at greater risk despite similar environmental circumstances. The findings suggest that risk communication experts must attend to the social and environmental contexts of risk and coping when designing strategies around risk reducing behaviours. PMID:23805055

    Harmful cyanobacterial blooms have adversely impacted human and animal health for thousands of years. Recently, the health impacts of harmful cyanobacteria blooms are becoming more frequently detected and reported. However, reports of human and animal illnesses or deaths associated with harmful cyanobacteria blooms tend to be investigated and reported separately. Consequently, professionals working in human or in animal health do not always communicate findings related to these events with one another. Using the One Health concept of integration and collaboration among health disciplines, we systematically review the existing literature to discover where harmful cyanobacteria-associated animal illnesses and deaths have served as sentinel events to warn of potential human health risks. We find that illnesses or deaths among livestock, dogs and fish are all potentially useful as sentinel events for the presence of harmful cyanobacteria that may impact human health. We also describe ways to enhance the value of reports of cyanobacteria-associated illnesses and deaths in animals to protect human health. Efficient monitoring of environmental and animal health in a One Health collaborative framework can provide vital warnings of cyanobacteria-associated human health risks. PMID:25903764

    Introduction: Nursing has been identified as an occupation that has high levels of stress. Job stress brought about hazardous impacts not only on nurses’ health but also on their abilities to cope with job demands. Objectives: This study aimed at finding out the degree of work-related stress among the staff nurses and various determinants, which have a impact on it. Materials and Methods: Institutional-based cross-sectional study conducted on GNM qualified nurses. Predesigned and pre-tested questionnaire covering their sociodemographic variables in part I and professional life stress scale by David Fontana in part II. Analysis used was Chi-square test and logistic regression for various factors. Results: Risk for professional stress due to poor and satisfactory doctor's attitude was found about 3 and 4 times more than with excellent attitude of doctors toward the staff nurses. A statistically significant association (P < 0.024) between department of posting and level of stress. Nurses reported that they had no time for rest, of whom 42% were suffering from moderate-to-severe stress. The nurses who felt that the job was not tiring were found to be less stressed as those who perceived job as tiring (OR = 0.43). Conclusion: The main nurses’ occupational stressors were poor doctor's attitude, posting in busy departments (emergency/ICU), inadequate pay, too much work, and so on. Thus, hospital managers should initiate strategies to reduce the amount of occupational stress and should provide more support to the nurses to deal with the stress. PMID:25568598

Subjects Finnish cardiovascular risk subjects (n =?904) without established cardiovascular disease, renal disease, or known diabetes. Main outcome measures Ankle-brachial index (ABI), estimated glomerular filtration rate (eGFR), oral glucose tolerance test, and total cardiovascular risk using SCORE risk charts. Results According to the SCORE risk charts, 27.0% (95% CI 23.1–31.2) of the women and 63.1% (95% CI 58.3–67.7) of the men (p risk subjects. Of the women classified as low-risk subjects according to SCORE, 25% had either subclinical peripheral arterial disease or renal insufficiency. Conclusions The SCORE system does not take into account cardiovascular risk factors typical in women, and thus underestimates their total cardiovascular risk. Measurement of ABI and eGFR in primary care might improve cardiovascular risk assessment. especially in women. PMID:22643155

    Experience in European health insurance exchanges indicates that even with the best risk-adjustment formulas, insurers have substantial incentives to engage in risk selection. The potentially most worrisome form of risk selection is skimping on the quality of care for underpriced high-cost patients-that is, patients for whom insurers are compensated at a rate lower than the predicted health care expenses of these patients. In this article we draw lessons for the United States from twenty years of experience with health insurance exchanges in Europe, where risk selection is a serious problem. Mistakes by European legislators and inadequate evaluation criteria for risk selection incentives are discussed, as well as strategies to reduce risk selection and the complex trade-off among selection (through quality skimping), efficiency, and affordability. Recommended improvements to the risk-adjustment process in the United States include considering the adoption of risk adjusters used in Europe, investing in the collection of data, using a permanent form of risk sharing, and replacing the current premium "band" restrictions with more flexible restrictions. Policy makers need to understand the complexities of regulating competitive health insurance markets and to prevent risk selection that threatens the provision of good-quality care for underpriced high-cost patients.

    Heart disease is the leading cause of death worldwide. Therefore, assessing the risk of its occurrence is a crucial step in predicting serious cardiac events. Identifying heart disease risk factors and tracking their progression is a preliminary step in heart disease risk assessment. A large number of studies have reported the use of risk factor data collected prospectively. Electronic health record systems are a great resource of the required risk factor data. Unfortunately, most of the valuable information on risk factor data is buried in the form of unstructured clinical notes in electronic health records. In this study, we present an information extraction system to extract related information on heart disease risk factors from unstructured clinical notes using a hybrid approach. The hybrid approach employs both machine learning and rule-based clinical text mining techniques. The developed system achieved an overall microaveraged F-score of 0.8302. PMID:26380290

  14. Risk Assessment in the UK Health and Safety System: Theory and Practice

    PubMed Central

    2010-01-01

    In the UK, a person or organisation that creates risk is required to manage and control that risk so that it is reduced 'So Far As Is Reasonably Practicable' (SFAIRP). How the risk is managed is to be determined by those who create the risk. They have a duty to demonstrate that they have taken action to ensure all risk is reduced SFAIRP and must have documentary evidence, for example a risk assessment or safety case, to prove that they manage the risks their activities create. The UK Health and Safety Executive (HSE) does not tell organisations how to manage the risks they create but does inspect the quality of risk identification and management. This paper gives a brief overview of where responsibility for occupational health and safety lies in the UK, and how risk should be managed through risk assessment. The focus of the paper is three recent major UK incidents, all involving fatalities, and all of which were wholly avoidable if risks had been properly assessed and managed. The paper concludes with an analysis of the common failings of risk assessments and key actions for improvement. PMID:22953158

    2008-02-01

    Radon and overhead powerlines are two radiation risk cases that have raised varying levels of concern among the general public and experts. Despite both involving radiation-a typically feared and unseen health hazard-individuals' perceptions of the two risk cases may invoke rather different factors. We examined individual and geographic-contextual factors influencing public perceptions of the health risks of indoor radon gas and overhead powerlines in a comparative research design, utilizing a postal questionnaire with 1,528 members of the general public (response rate 28%) and multilevel modeling techniques. This study found that beliefs about the two risk cases mainly differed according to the level of "exposure"-defined here in terms of spatial proximity. We argue that there are two alternative explanations for this pattern of findings: that risk perception itself varies directly with proximity, or that risk is more salient to concerned people in the exposed areas. We also found that while people living in high radon areas are more concerned about the risks of indoor radon gas, they find these risks more acceptable and have more trust in authorities. These results might reflect the positive effects of successive radon campaigns in high radon areas, which may have raised awareness and concern, and at the same time may have helped to increase trust by showing that the government takes the health risks of indoor radon gas seriously, suggesting that genuine risk communication initiatives may have positive impacts on trust in risk management institutions.

    Objective To assess health risks associated with inhalation exposure to formaldehyde and benzene mainly emitted from building and decoration materials in newly remodeled indoor spaces in Beijing. Methods We tested the formaldehyde and benzene concentrations in indoor air of 410 dwellings and 451 offices remodeled within the past year, in which the occupants had health concerns about indoor air quality. To assess non-carcinogenic health risks, we compared the data to the health guidelines in China and USA, respectively. To assess carcinogenic health risks, we first modeled indoor personal exposure to formaldehyde and benzene using the concentration data, and then estimated the associated cancer risks by multiplying the indoor personal exposure by the Inhalation Unit Risk values (IURs) provided by the U.S. EPA Integrated Risk Information System (U.S. EPA IRIS) and the California Office of Environmental Health Hazard Assessment (OEHHA), respectively. Results (1) The indoor formaldehyde concentrations of 85% dwellings and 67% offices were above the acute Reference Exposure Level (REL) recommended by the OEHHA and the concentrations of all tested buildings were above the chronic REL recommended by the OEHHA; (2) The indoor benzene concentrations of 12% dwellings and 32% offices exceeded the reference concentration (RfC) recommended by the U.S. EPA IRIS; (3) The median cancer risks from indoor exposure to formaldehyde and benzene were 1,150 and 106 per million (based on U.S. EPA IRIS IURs), 531 and 394 per million (based on OEHHA IURs). Conclusions In the tested buildings, formaldehyde exposure may pose acute and chronic non-carcinogenic health risks to the occupants, whereas benzene exposure may pose chronic non-carcinogenic risks to the occupants. Exposure to both compounds is associated with significant carcinogenic risks. Improvement in ventilation, establishment of volatile organic compounds (VOCs) emission labeling systems for decorating and refurbishing materials are recommended to reduce indoor VOCs exposure.

    According to the framework of “Pressure-State-Response”, this study established an indicator system which can reflect comprehensive risk of environment and health for an area at large scale. This indicator system includes 17 specific indicators covering social and economic development, pollution emission intensity, air pollution exposure, population vulnerability, living standards, medical and public health, culture and education. A corresponding weight was given to each indicator through Analytical Hierarchy Process (AHP) method. Comprehensive risk assessment of the environment and health of 58 counties was conducted in the Jiangsu province, China, and the assessment result was divided into four types according to risk level. Higher-risk counties are all located in the economically developed southern region of Jiangsu province and relatively high-risk counties are located along the Yangtze River and Xuzhou County and its surrounding areas. The spatial distribution of relatively low-risk counties is dispersive, and lower-risk counties mainly located in the middle region where the economy is somewhat weaker in the province. The assessment results provide reasonable and scientific basis for Jiangsu province Government in formulating environment and health policy. Moreover, it also provides a method reference for the comprehensive risk assessment of environment and health within a large area (provinces, regions and countries). PMID:26371016

    2015-01-01

    Background The escalating cost of global health care is driving the development of new technologies to identify early indicators of an individual’s risk of disease. Traditionally, epidemiologists have identified such risk factors using medical databases and lengthy clinical studies but these are often limited in size and cost and can fail to take full account of diseases where there are social stigmas or to identify transient acute risk factors. Objective Here we report that Web search engine queries coupled with information on Wikipedia access patterns can be used to infer health events associated with an individual user and automatically generate Web-based risk markers for some of the common medical conditions worldwide, from cardiovascular disease to sexually transmitted infections and mental health conditions, as well as pregnancy. Methods Using anonymized datasets, we present methods to first distinguish individuals likely to have experienced specific health events, and classify them into distinct categories. We then use the self-controlled case series method to find the incidence of health events in risk periods directly following a user’s search for a query category, and compare to the incidence during other periods for the same individuals. Results Searches for pet stores were risk markers for allergy. We also identified some possible new risk markers; for example: searching for fast food and theme restaurants was associated with a transient increase in risk of myocardial infarction, suggesting this exposure goes beyond a long-term risk factor but may also act as an acute trigger of myocardial infarction. Dating and adult content websites were risk markers for sexually transmitted infections, such as human immunodeficiency virus (HIV). Conclusions Web-based methods provide a powerful, low-cost approach to automatically identify risk factors, and support more timely and personalized public health efforts to bring human and economic benefits.

    Background: To assess the concept of children concerning their health and its risk factors, a group of primary and middle school students were asked to draw a few relevant pictures in order to deeply explore the comprehension of this key group. Methods: In this cross-sectional study 1165 students, aged 7-15 years old, selected through random stratified sampling, were asked to draw a number of eight paintings, four paintings on health concepts, and the other four on health risk factors. The paintings were then assessed by two independent observers, and their themes and contents were abstracted and analysed. Results: The students drew a total of 2330 paintings, 1165 paintings on the concept of health, and 1165 paintings on health risk factors. The most and least expressed health concepts concerned “mental health” and “healthy diet” (73.3% and 4.8%, respectively). Considering health risk factors, “unhealthy diet” and the two concepts of “environmental hazards” and “neglected personal hygiene” had the most (95%) and least (1.4% each) frequencies. Students in public schools, primary level and girls drew more pictures about health concept or/and its risk factors (P<0.05). The association between parents’ education level and the numbers of pictures were not statistically significant. Conclusion: Although students had a broad view about health and its risk factors, generally little attention had been paid to some of the main aspects such as physical activity, healthy diet, mental and oral health, and environmental hazards. In addition, it seems that parents’ educational level, as one of the main socio-economic factors, did not have any significant impact on their concepts. PMID:24596834

    Most diseases, injuries, and other health conditions experienced by working people are multifactorial, especially as the workforce ages. Evidence supporting the role of work and personal risk factors in the health of working people is frequently underused in developing interventions. Achieving a longer, healthy working life requires a comprehensive preventive approach. To help develop such an approach, we evaluated the influence of both occupational and personal risk factors on workforce health. We present 32 examples illustrating 4 combinatorial models of occupational hazards and personal risk factors (genetics, age, gender, chronic disease, obesity, smoking, alcohol use, prescription drug use). Models that address occupational and personal risk factors and their interactions can improve our understanding of health hazards and guide research and interventions. PMID:22021293

    The public health risk of ionising radiation released from the coal-fired energy chain, 20 deaths (GW a)(-1), is about 18 times that of the nuclear energy chain, 1.1 deaths (GW a)(-1), in China. The main contributors to the fatality risk for the former are the public dose caused by the use of coal ash and the occupational exposure caused by radon and its progeny in coal mines. The total health risk (but excluding low probability/high consequence accidents) of the coal-fired energy chain, 57.1 deaths (GW a)(-1), is about 12 times of that of the nuclear energy chain, 4.6 deaths (GW a)(-1). The health risk of coal-fired energy chain could be significantly reduced if technique and management were improved. Even then the risk of the coal-fired energy chain is about 4.4 times that of the nuclear energy chain. PMID:9594114

    Physical health screenings were conducted by researchers and peer wellness specialists for adults attending publicly-funded community mental health programs. A total of 457 adults with serious mental illnesses attended health fairs in 4 U.S. states and were screened for 8 common medical co-morbidities and health risk factors. Also assessed were self-reported health competencies, medical conditions, and health service utilization. Compared to non-institutionalized U.S. adults, markedly higher proportions screened positive for obesity (60%), hypertension (32%), diabetes (14%), smoking (44%), nicotine dependence (62%), alcohol abuse (17%), drug abuse (11%), and coronary heart disease (10%). A lower proportion screened positive for hyperlipidemia (7%). Multivariable random regression analysis found significant pre- to post-screening increases in participants’ self-rated abilities for health practices, competence for health maintenance, and health locus of control. Screening identified 82 instances of undiagnosed diabetes, hypertension or hyperlipidemia, and 76 instances where these disorders were treated but uncontrolled. These results are discussed in the context of how this global public health approach holds promise for furthering the goal of integrating health and mental health care. PMID:25875181

  12. Assessing the Health and Performance Risks of Carbon Dioxide Exposures

    NASA Technical Reports Server (NTRS)

    James, John T.; Meyers, V. E.; Alexander, D.

    2010-01-01

    Carbon dioxide (CO2) is an anthropogenic gas that accumulates in spacecraft to much higher levels than earth-normal levels. Controlling concentrations of this gas to acceptable levels to ensure crew health and optimal performance demands major commitment of resources. NASA has many decades of experience monitoring and controlling CO2, yet we are uncertain of the levels at which subtle performance decrements develop. There is limited evidence from ground-based studies that visual disturbances can occur during brief exposures and visual changes have been noted in spaceflight crews. These changes may be due to CO2 alone or in combination with other known spaceflight factors such as increased intracranial pressure due to fluid shifts. Discerning the comparative contribution of each to performance decrements is an urgent issue if we hope to optimize astronaut performance aboard the ISS. Long-term, we must know the appropriate control levels for exploration-class missions to ensure that crewmembers can remain cooperative and productive in a highly stressful environment. Furthermore, we must know the magnitude of interindividual variability in susceptibility to the adverse effects of CO2 so that the most tolerant crewmembers can be identified. Ground-based studies have been conducted for many years to set exposure limits for submariners; however, these studies are typically limited and incompletely reported. Nonetheless, NASA, in cooperation with the National Research Council, has set exposure limits for astronauts using this limited database. These studies do not consider the interactions of spaceflight-induced fluid shifts and CO2 exposures. In an attempt to discern whether CO2 levels affect the incidence of headache and visual disturbances in astronauts we performed a retrospective study comparing average CO2 levels and the prevalence of headache and visual disturbances. Our goal is to narrow gaps in the risk profile for in-flight CO2 exposures. Such studies can provide no more than partial answers to the questions of environmental interactions, interindividual variability, and optimal control levels. Future prospective studies should involve assessment of astronaut well being using sophisticated measures during exposures to levels of CO2 in the range from 2 to 8 mmHg.

    Rossi, Giuseppe; Sarto, Simone Del; Marchi, Marco

    2014-04-22

    To monitor a health event in patients with a specific risk of developing the event, a risk-adjusted cumulative sum chart is needed. The risk-adjusted cumulative sum chart proposed in the literature has some limitations. Setting appropriate control limits is not straightforward, there is no simple formula for constructing them, and they remain sensitive to changes in the underlying risk distribution and the baseline incidence rate. To overcome these limits, we propose a new risk-adjusted Bernoulli cumulative sum chart as a simple and efficient solution. Analyses of simulated and real data sets illustrate the performance and usefulness of the proposed procedure. PMID:24756935

    The authors used the Risk Perception Attitude framework, which is grounded in the Extended Parallel Process Model, to predict people's intentions to seek health information. In an online survey, 689 participants recruited from a crowdsource website were queried about their anticipated health information seeking, perceived risk, and efficacy in response to four scenarios pertaining to hypertension, hypercholesterolemia, alcohol dependence, and diabetes. Each participant was categorized for each scenario as responsive (higher risk, higher efficacy), avoidant (higher risk, lower efficacy), proactive (lower risk, higher efficacy), or indifferent (lower risk, lower efficacy). As predicted, responsive individuals were more likely to seek information than avoidant individuals, but only in three of the four scenarios. Also as expected, there was no difference between proactive and indifferent individuals' likelihood of seeking health information for any scenario. Risk and efficacy, while significant predictors of anticipated health information seeking, left much of the variance unexplained. An analysis of the reasons for information seeking and nonseeking among nonconforming cases suggests that a wider range of influences on health information seeking should be investigated, including curiosity, prior knowledge, social expectations, and situational norms.

    2014-01-01

    In this chapter, we review evidence from the human factors literature that verbal and visual formats can help increase the understanding of numerical risk information in health care. These visual representations of risk are grounded in empirically supported theory. As background, we first review research showing that people often have difficulty understanding numerical risks and benefits in health information. In particular, we discuss how understanding the meanings of numbers results in healthier decisions. Then, we discuss the processes that determine how communication of numerical risks can enhance (or degrade) health judgments and decisions. Specifically, we examine two different approaches to risk communication: a traditional approach and fuzzy-trace theory. Applying research on the complications of understanding and communicating risks, we then highlight how different visual representations are best suited to communicating different risk messages (i.e., their gist). In particular, we review verbal and visual messages that highlight gist representations that can better communicate health information and improve informed decision making. This discussion is informed by human factors theories and methods, which involve the study of how to maximize the interaction between humans and the tools they use. Finally, we present implications and recommendations for future research on human factors in health care. PMID:24999307

  16. Assessing the Risks to Human Health in Heterogeneous Aquifers under Uncertainty

    NASA Astrophysics Data System (ADS)

    de Barros, Felipe

    2015-04-01

    Reliable quantification of human health risk from toxic chemicals present in groundwater is a challenging task. The main difficulty relies on the fact that many of the components that constitute human health risk assessment are uncertain and requires interdisciplinary knowledge. Understanding the impact from each of these components in risk estimation can provide guidance for decision makers to manage contaminated sites and best allocate resources towards minimal prediction uncertainty. This presentation will focus on the impact of aquifer heterogeneity in human health risk. Spatial heterogeneity of the hydrogeological properties can lead to the formation of preferential flow channels which control the plume spreading rates and travel time statistics, both which are critical in assessing the risk level. By making use of an integrated hydrogeological-health stochastic framework, the significance of characteristic length scales (e.g. characterizing flow, transport and sampling devices) in both controlling the uncertainty of health risk and determining data needs is highlighted. Through a series of examples, we show how fundamental knowledge on the main physical mechanisms affecting solute pathways are necessary to understand the human health response to varying drivers.

    Saksena, Priyanka; Hsu, Justine; Evans, David B.

    2014-01-01

    Financial risk protection is a key component of universal health coverage (UHC), which is defined as access to all needed quality health services without financial hardship. As part of the PLOS Medicine Collection on measurement of UHC, the aim of this paper is to examine and to compare and contrast existing measures of financial risk protection. The paper presents the rationale behind the methodologies for measuring financial risk protection and how this relates to UHC as well as some empirical examples of the types of measures. Additionally, the specific challenges related to monitoring inequalities in financial risk protection are discussed. The paper then goes on to examine and document the practical challenges associated with measurement of financial risk protection. This paper summarizes current thinking on the area of financial risk protection, provides novel insights, and suggests future developments that could be valuable in the context of monitoring progress towards UHC.

  8. Assessing Sexually Intrusive Thoughts: Parsing Unacceptable Thoughts on the Dimensional Obsessive-Compulsive Scale.

    PubMed

    Wetterneck, Chad T; Siev, Jedidiah; Adams, Thomas G; Slimowicz, Joseph C; Smith, Angela H

    2015-07-01

    Sexual obsessions are a common symptom of obsessive-compulsive disorder (OCD), often classified in a broader symptom dimension that includes aggressive and religious obsessions, as well. Indeed, the Dimensional Obsessive-Compulsive Scale (DOCS) Unacceptable Thoughts Scale includes obsessional content relating to sexual, violent, and religious themes associated with rituals that are often covert. However, there is reason to suspect that sexual obsessions differ meaningfully from other types of unacceptable thoughts. We conducted two studies to evaluate the factor structure, initial psychometric characteristics, and associated clinical features of a new DOCS scale for sexually intrusive thoughts (SIT). In the first study, nonclinical participants (N=475) completed the standard DOCS with additional SIT questions and we conducted an exploratory factor analysis on all items and examined clinical and cognitive correlates of the different scales, as well as test-retest reliability. The SIT Scale was distinct from the Unacceptable Thoughts Scale and was predicted by different obsessional cognitions. It had good internal consistency and there was evidence for convergent and divergent validity. In the second study, we examined the relationships among the standard DOCS and SIT scales, as well as types of obsessional cognitions and symptom severity, in a clinical sample of individuals with OCD (N=54). There were indications of both convergence and divergence between the Unacceptable Thoughts and SIT scales, which were strongly correlated with each other. Together, the studies demonstrate the potential utility of assessing sexually intrusive thoughts separately from the broader category of unacceptable thoughts. PMID:26163717

    Kirkham, Heather S; Clark, Bobby L; Bolas, Cheryl A; Lewis, Geraint Hywel; Jackson, Allison S; Fisher, Don; Duncan, Ian

    2015-02-01

    The purpose of this retrospective, longitudinal study was to assess longitudinal associations between modifiable health risks and workplace absenteeism and presenteeism and to estimate lost productivity costs. Across the 4-year study period (2007-2010), 17,089 unique employees from a large US computer manufacturer with a highly technical workforce completed at least 1 health risk assessment. Generalized estimating equation models were used to estimate the mean population-level absenteeism and presenteeism for 11 modifiable health risks and adjust for 9 sociodemographic and employment-related factors. Because patient age was highly correlated with several other variables, the analysis was stratified by age (<45 vs. ?45 years). For all ages, poor emotional health, inadequate exercise, tobacco use, and having a body mass index (BMI) greater than 35 (all P<.05) were consistently associated with both absenteeism and presenteeism. Having a BMI over 35 and poor emotional health were associated with the largest impact in absenteeism (0.46 days) and presenteeism (4.03 days), respectively. Younger and older workers had similar associations between health risks and presenteeism; however, hypertension, blood sugar, inadequate exercise, and alcohol were associated (P?.01) with greater absenteeism among older but not younger workers. The results suggest that productivity loss is strongly related to emotional health and obesity-related health risks (eg, BMI, exercise) but differs by age. These findings could help prioritize preventive health programs offered by employers at their worksite health centers. Given the aging of the US workforce, keeping older workers healthy and productive will be crucial to remaining competitive in the global economy. (Population Health Management 2015;18:30-38).

  12. Risk levels for suffering a traffic injury in primary health care. The LESIONAT* project

    PubMed Central

    2010-01-01

    Background Literature shows that not only are traffic injuries due to accidents, but that there is also a correlation between different chronic conditions, the consumption of certain types of drugs, the intake of psychoactive substances and the self perception of risk (Health Belief Model) and the impact/incidence of traffic accidents. There are few studies on these aspects in primary health care. The objectives of our study are: Main aim: To outline the distribution of risk factors associated with Road Traffic Injuries (RTI) in a driving population assigned to a group of primary health care centres in Barcelona province. Secondly, we aim to study the distribution of diverse risk factors related to the possibility of suffering an RTI according to age, sex and population groups, to assess the relationship between these same risk factors and self risk perception for suffering an RTI, and to outline the association between the number of risk factors and the history of reported collisions. Methods/Design Design: Cross-sectional, multicentre study. Setting: 25 urban health care centres. Study population: Randomly selected sample of Spanish/Catalan speakers age 16 or above with a medical register in any of the 25 participating primary health care centres. N = 1540. Unit of study: Basic unit of care, consisting of a general practitioner and a nurse, both of whom caring for the same population (1,500 to 2,000 people per unit). Instruments of measurement: Data collection will be performed using a survey carried out by health professionals, who will use the clinical registers and the information reported by the patient during the visit to collect the baseline data: illnesses, medication intake, alcohol and psychoactive consumption, and self perception of risk. Discussion We expect to obtain a risk profile of the subjects in relation to RTI in the primary health care field, and to create a group for a prospective follow-up.

  11. Health risk assessment of kerosene usage in an informal settlement in Durban, South Africa

    NASA Astrophysics Data System (ADS)

    Muller, E.; Diab, R. D.; Binedell, M.; Hounsome, R.

    In Durban, South Africa studies have shown that more than seven out of ten households in low-income metropolitan areas rely on kerosene for domestic purposes, leading to widespread problems of poor indoor air quality. In light of the known health effects of kerosene usage, this study aimed to quantify the health risk for people living in a densely populated informal settlement known as Cato Crest within the Durban metropolitan area. The pollutants investigated included nitrogen dioxide, benzene and toluene. Nitrogen dioxide is known to affect both respiratory and immune systems, benzene is carcinogenic while toluene has a neurological health end point. All three pollutants are harmful when inhaled. The United States Environmental Protection Agency (US EPA) health risk assessment (HRA) framework was applied. Information on the exposure patterns of residents in Cato Crest were acquired through questionnaires in which data on fuel use, building structure, cooking habits and time-activity patterns were collected. Air quality monitoring of nitrogen dioxide and volatile organic compounds was also conducted in the households. The time-activity pattern survey revealed that the exposure periods of individuals in Cato Crest were far greater than the default exposure periods used by the US EPA. The results of the HRA showed that the residents of Cato Crest may experience significant health risks as a result of kerosene usage in their homes. Exposure to 1-h nitrogen dioxide concentration is not likely to produce adverse health effects, whereas exposure over a 24-h period indicates a potential health risk to sensitive individuals in two of the households when US EPA exposure values are used and in all of the households when locally derived exposure values are used. Benzene poses a health risk to sensitive individuals in 50% of the households when local exposure parameters are used, whereas there is no health risk associated with exposure to toluene.

    2015-07-01

    This study provides a preliminary investigation of the role of stress management in multiple behavior change. Risk status on stress management and five health behaviors (healthy eating, exercise, alcohol, smoking, and depression management) was assessed before and after a multiple behavior change intervention. Findings suggested a link between stress management and a worse health risk behavior profile at baseline. Results also showed relationships between improved stress management over 6 months and heightened odds of improving on specific behaviors as well as improving one's overall behavioral risk profile. Particularly strong links between stress management and energy balance and other affective behaviors were observed. PMID:24165862

    2011-07-01

    We investigate the relationship between exposure to Hurricanes Katrina and/or Rita and mental health resilience by vulnerability status, with particular focus on the mental health outcomes of single mothers versus the general public. We advance a measurable notion of mental health resilience to disaster events. We also calculate the economic costs of poor mental health days added by natural disaster exposure. Negative binomial analyses show that hurricane exposure increases the expected count of poor mental health days for all persons by 18.7% (95% confidence interval [CI], 7.44-31.14%), and by 71.88% (95% CI, 39.48-211.82%) for single females with children. Monthly time-series show that single mothers have lower event resilience, experiencing higher added mental stress. Results also show that the count of poor mental health days is sensitive to hurricane intensity, increasing by a factor of 1.06 (95% CI, 1.02-1.10) for every billion (U.S.$) dollars of damage added for all exposed persons, and by a factor of 1.08 (95% CI, 1.03-1.14) for single mothers. We estimate that single mothers, as a group, suffered over $130 million in productivity loss from added postdisaster stress and disability. Results illustrate the measurability of mental health resilience as a two-dimensional concept of resistance capacity and recovery time. Overall, we show that natural disasters regressively tax disadvantaged population strata. PMID:21303401

    This study examined the health-promoting lifestyles and cardio-metabolic risks among international students in Korea. This descriptive, cross-sectional study design enrolled a convenience sample of 118 international students at a university in Korea. Collected data included items from the Health-promoting Lifestyle Profile (II) scale and cardiovascular risk factors. The participants had a moderately health-promoting lifestyle (2.5 of 4). Men engaged in more physical activity than did women (p = .002). The most prevalent risk factor was elevated blood lipid profiles (26.3%), followed by overweight/obesity (25.4%), elevated blood pressure (17.8%), and elevated fasting glucose levels (5.1%). More than half of the participants (54.2%) had one or more cardiac risk factors, and these participants also scored lower in health-promoting lifestyle factors than other students (p = .034). Regular health check-ups are needed to identify the cardio-metabolic risks of international students. A university-based programme aimed at promoting healthy lifestyles could help prevent cardio-metabolic risks among international students. PMID:26281410

    The primary purpose of this manual is to provide instructions on how to install and use the ORAMUS (Ozone Risk AssessMent UtilitieS) software. ORAMUS is a DOS-based software system that allows you to calculate and view risk estimates for health effects attributable to short- and long-term exposure to tropospheric ozone.

    Study Objectives: Short and long sleep duration have been linked with higher rates of comorbid medical and mental health issues, as well as increased mortality. The current study examined the association between sleep duration, mental health problems, and health risk behaviors in a large sample of U.S. Afghanistan/Iraq era veterans. Design: NA. Setting: Mid-Atlantic VA Medical Center(s). Patients/Participants: The sample (N = 1,640) included 20% women (n = 333) and had an average age of 37 years (SD = 10.0). Interventions: NA. Measurements and Results: Results from logistic regression analyses that included age, minority status, gender, military rank, number of deployments, combat exposure, and health risk behaviors as covariates indicated that very short sleep duration (? 5 h of sleep) and long sleep duration (? 9 h) were each associated with increased odds of current post traumatic stress disorder (PTSD), major depressive disorder (MDD), and smoking; while poor sleep quality was associated with PTSD, panic disorder (PD), MDD, suicidal ideation (SI), and risky drinking. Conclusions: Sleep duration may be an important marker for psychiatric and health risk behavior problems, and our results suggest that clinical assessment of sleep disturbance in this veteran group is warranted to assess for both short and long sleep.

    The work described in this report is part of a larger risk assessment sponsored by the U.S. Environmental Protection Agency. Earlier efforts developed exposure-response relationships for acute health effects among populations engaged in heavy exertion. Those efforts also developed a probabilistic national ambient air quality standards exposure model and a general methodology for integrating probabilistic exposure-response relation- ships and exposure estimates to calculate overall risk results. Recently published data make it possible to model additional health endpoints (for exposure at moderate exertion), including hospital admissions. New air quality and exposure estimates for alternative national ambient air quality standards for ozone are combined with exposure-response models to produce the risk results for hospital admissions and acute health effects. Sample results explain the methodology and introduce risk output formats.

    Indigenous people experience poorer health than non-Indigenous people, and this well-described inequality has been observed in many countries. The contribution of different risk factors to the health ‘gap’ has understandably focussed on those factors for which there are sufficient data. However, this has precluded environmental risk factors – those present in air, water, food, and soil – due to a lack of data describing exposures and outcomes. These risk factors are demonstrably important at the global scale, as highlighted by the 2010 Global Burden of Disease study. Here, we describe how a greater focus on environmental risk factors is required in order to define their role in the Indigenous health gap. We use the Australian context as a case study of an issue we feel has global analogues and relevance. Suggestions for how and why this situation should be remedied are presented and discussed.

    Extremely low frequency electromagnetic radiation has received considerable attention recently as a possible threat to the health of persons living near high tension electric power lines, distribution substations, and even in close proximity to common household electric appliances. Results of epidemiological and laboratory research are examined to assess risks associated with magnetic fields generated by extremely low frequency electromagnetic sources. Health risks associated with such fields include a wide variety of ills ranging from disruption of normal circadian rhythms to childhood cancers. Risk assessment has been particularly difficult to determine in light of an ostensible lack of a dose-response relationship. Current media sensation fueled in part by an equivocal position adopted by the United States Environmental Protection Agency has contributed to the controversy. Recommendations for prudent avoidance of possible dangers are presented along with policy implications concerning health risks associated with magnetic fields.32 references.

    The fundamental goal of this article is to describe, define, and analyze the components of the risk characterization process for occupational exposures. Current methods are described for the probabilistic characterization of exposure, including newer techniques that have increasing applications for assessing data from occupational exposure scenarios. In addition, since the probability of health effects reflects variability in the exposure estimate as well as the dose-response curve—the integrated considerations of variability surrounding both components of the risk characterization provide greater information to the occupational hygienist. Probabilistic tools provide a more informed view of exposure as compared to use of discrete point estimates for these inputs to the risk characterization process. Active use of such tools for exposure and risk assessment will lead to a scientifically supported worker health protection program. Understanding the bases for an occupational risk assessment, focusing on important sources of variability and uncertainty enables characterizing occupational risk in terms of a probability, rather than a binary decision of acceptable risk or unacceptable risk. A critical review of existing methods highlights several conclusions: (1) exposure estimates and the dose-response are impacted by both variability and uncertainty and a well-developed risk characterization reflects and communicates this consideration; (2) occupational risk is probabilistic in nature and most accurately considered as a distribution, not a point estimate; and (3) occupational hygienists have a variety of tools available to incorporate concepts of risk characterization into occupational health and practice.

  6. Crime, violence, and behavioral health: collaborative community strategies for risk mitigation.

    2015-06-01

    Criminal conduct is not always violent, and violence does not always lead to criminal charges. Moreover, crime and violence have multifaceted etiologies. Most violence in society is not attributable to mental illness. Where there is a small relationship between violence and mental illness, the risk of violence increases for individuals with substance use histories. Underlying trauma can also play a role. Antisocial attitudes, behaviors, and peer groups further increase the risk that individuals, including those with mental illness, will find themselves at risk of criminal recidivism. Criminal histories among public mental health populations, and mental health and substance use disorders among criminal populations are each higher than general population comparisons. Care within behavioral health settings should therefore target decreased criminal recidivism and decreased violence as part of recovery for those individuals at risk, using trauma-informed approaches and peer supports. Interventions that show promise bring criminal justice and behavioral health systems together, and include police-based diversion, specialty courts, court-based alternatives to incarceration, and coordinated re-entry programs. This article reviews these options along with specific risk management strategies, such as using risk, needs, and responsivity factors as a means of improving overall outcomes for persons with mental illness, while minimizing their risk of further criminalization and victimization.

    Inhalatory and dermal exposures of on-duty vehicle inspection workers to polycyclic aromatic hydrocarbons (PAHs) in Beijing were investigated from April 18 to May 17, 2011. Exposure levels to particulate PAHs for the vehicle inspection workers at gasoline, bus and diesel lines were found to be 56.07 ng m(-3), 111.72 ng m(-3) and 199.80 ng m(-3), respectively. A probabilistic risk assessment framework was integrated with the toxic equivalence factors (TEFs) and the incremental lifetime cancer risk (ILCR) approaches to quantitatively estimate the exposure risk for vehicle inspection workers of the three work lines. The median values of inhalation risk were estimated to be 3.7 × 10(-7), 5.0 × 10(-7) and 1.37 × 10(-6), respectively, while the median dermal ILCR values were 7.05 × 10(-6), 6.98 × 10(-6) and 1.28 × 10(-5), respectively for gasoline, bus, and diesel inspection workers. Total ILCR was higher than the acceptable risk level of 10(-6), indicating unacceptable potential cancer risk. PMID:23738361

    Objective: To analyze the prevalence and factors associated with the co-occurrence of health risk behaviors in adolescents. Methods: A cross-sectional study was performed with a sample of high school students from state public schools in Pernambuco, Brazil (n=4207, 14-19 years old). Data were obtained using a questionnaire. The co-occurrence of health risk behaviors was established based on the sum of five behavioral risk factors (low physical activity, sedentary behavior, low consumption of fruits/vegetables, alcohol consumption and tobacco use). The independent variables were gender, age group, time of day attending school, school size, maternal education, occupational status, skin color, geographic region and place of residence. Data were analyzed by ordinal logistic regression with proportional odds model. Results: Approximately 10% of adolescents were not exposed to health risk behaviors, while 58.5% reported being exposed to at least two health risk behaviors simultaneously. There was a higher likelihood of co-occurrence of health risk behaviors among adolescents in the older age group, with intermediate maternal education (9-11 years of schooling), and who reported living in the driest (semi-arid) region of the state of Pernambuco. Adolescents who reported having a job and living in rural areas had a lower likelihood of co-occurrence of risk behaviors. Conclusions: The findings suggest a high prevalence of co-occurrence of health risk behaviors in this group of adolescents, with a higher chance in five subgroups (older age, intermediate maternal education, the ones that reported not working, those living in urban areas and in the driest region of the state).

    Background: Environmental risks to health in the United Arab Emirates (UAE) have shifted rapidly from infectious to noninfectious diseases as the nation has developed at an unprecedented rate. In response to public concerns over newly emerging environmental risks, the Environment Agency–Abu Dhabi commissioned a multidisciplinary environmental health strategic planning project. Objectives: In order to develop the environmental health strategic plan, we sought to quantify the illnesses and premature deaths in the UAE attributable to 14 environmental pollutant categories, prioritize these 14 risk factors, and identify interventions. Methods: We estimated the disease burden imposed by each risk factor using an attributable fraction approach, and we prioritized the risks using an empirically tested stakeholder engagement process. We then engaged government personnel, scientists, and other stakeholders to identify interventions. Results: The UAE’s environmental disease burden is low by global standards. Ambient air pollution is the leading contributor to premature mortality [~ 650 annual deaths; 95% confidence interval (CI): 140, 1,400]. Risk factors leading to > 10,000 annual health care facility visits included occupational exposures, indoor air pollution, drinking water contamination, seafood contamination, and ambient air pollution. Among the 14 risks considered, on average, outdoor air pollution was ranked by the stakeholders as the highest priority (mean rank, 1.4; interquartile range, 1–2) and indoor air pollution as the second-highest priority (mean rank 3.3; interquartile range, 2–4). The resulting strategic plan identified 216 potential interventions for reducing environmental risks to health. Conclusions: The strategic planning exercise described here provides a framework for systematically deciding how to invest public funds to maximize expected returns in environmental health, where returns are measured in terms of reductions in a population’s environmental burden of disease.

    The degree to which society will come to accept potential health risks associated with municipal waste-to-energy plants depends on three factors: the reliability with which exposure and adverse health effects associated with facility emissions can be described, quantified, and gradually reduced; the relative magnitude of the risks compared with those of other waste management options, especially landfilling and recycling; and the relative magnitude of the risks compared with those of more familiar activities, such as driving, flying, smoking, and eating peanut butter sandwiches. Progress in risk assessment has already improved quantification of human exposure to emissions through the food chain, as well as through other pathways within the general categories of inhalation, ingestion, and dermal contact. Where does this progress leave municipal refuse incineration relative to other risks This article explores that issue.

  20. Identification of Patient Safety Risks Associated with Electronic Health Records: A Software Quality Perspective.

    Virginio, Luiz A; Ricarte, Ivan Luiz Marques

    2015-01-01

    Although Electronic Health Records (EHR) can offer benefits to the health care process, there is a growing body of evidence that these systems can also incur risks to patient safety when developed or used improperly. This work is a literature review to identify these risks from a software quality perspective. Therefore, the risks were classified based on the ISO/IEC 25010 software quality model. The risks identified were related mainly to the characteristics of "functional suitability" (i.e., software bugs) and "usability" (i.e., interface prone to user error). This work elucidates the fact that EHR quality problems can adversely affect patient safety, resulting in errors such as incorrect patient identification, incorrect calculation of medication dosages, and lack of access to patient data. Therefore, the risks presented here provide the basis for developers and EHR regulating bodies to pay attention to the quality aspects of these systems that can result in patient harm. PMID:26262009

    This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed. The challenges of improving oral health are particularly great in developing countries. PMID:16211157

    Counselling or prescribing drugs during pregnancy requires health professionals to assess risk/benefit ratio for women and their baby. A misperception of the risk may lead to inappropriate decisions for pregnancy outcomes. The aim of the present study was to assess teratogenic and/or foetotoxic risk perception of common medications by general practitioners (GPs) and community pharmacists (CPs) from the Midi-Pyrenees area. Methods 103 GPs and 104 CPs were interviewed. For 21 given drugs, a visual-analogue scale was used to evaluate the risk to give birth to a malformed infant if the mother had taken the drug during first trimester of pregnancy. For 9 drugs, health professionals had to say if they thought there was a potential foetotoxic and/or neonatal risk when drugs were administered during late pregnancy. Results 97% and 91% of GPs and CPs respectively thought that isotretinoin and thalidomide are teratogenic and more than 80% thought that amoxicillin and acetaminophen are safe in early pregnancy. However, 19% of the GPs and 33% of CPs answered there were no teratogenic risk for valproate. Around 11% of both GPs and CPs said that warfarin was safe during pregnancy. For 22% of GPs and for 13% and 27% of CPs respectively, ibuprofen and enalapril were safe on late pregnancy. For each drug, mean value of perceived teratogenic risk by health professionals was higher than values that can be found in scientific references. Concerning isotretinoin, thalidomide and metoclopramide, perceived teratogenic risk was higher for CPs. Conclusion These data show that the potential teratogenic and foetotoxic risk of several commonly used drugs is unknown by health professionals. Conversely, GPs and CPs who think that a risk exists, overestimate it. This misperception can lead to inappropriate decisions for pregnancy outcomes. PMID:25170360

    Tuberculosis (TB) is one of the main public health problems in Sabah; 30% of the total number of TB cases reported in Malaysia every year occur in Sabah. The average incidence of TB among health care workers over the past 5 years is 280.4 per 100,000 population (1, Annual Report of Sabah State TB Control Programme, 1998). At present, there are no specific measures for the prevention of TB transmission in health care facilities. A case-control study was conducted among health care workers in Sabah in 2000-2001. Cases were health care workers with TB diagnosed between January 1990 and June 2000. Controls were health care workers without TB and working in the same facility as cases during the disease episode. The study attempted to identify risk factors for TB among the study population. Data were collected through structured interviews and review of patients' records. The notification rate of TB among health care workers was significantly higher than that to the general population (Z=4.893, p<0.01). The average notification rate of TB among health care workers over the last 5 years was two times higher than in the general population (280.4/100,000 compared to 153.9/100,000). Regression results showed that ethnicity, designation, family contact and TB related knowledge did not significantly contribute to the risk of contracting TB in this study. However, after controlling for the above factors, age, gender, history of TB contact outside the workplace (other than family contact), duration of service and failure to use respiratory protection when performing high-risk procedures, were the main risk factors of TB among health care workers. This study succeeded in identifying some of the risk factors of TB among health care workers. We managed to include the large ratio of controls to case (3:1) and those cases spanned over a period of 10 years. However, the findings from the study have to be applied with caution due to the limitations of this study, which include recall bias, dropouts, and small sample size. Based on the study findings, we recommend that health care workers in the first 10 years of service should take extra precautions, such as using respiratory protection when performing procedures that are considered to be of high risk with respect to TB infection. They should also undergo TB screening at least once every 2 years and, if symptomatic, offered prophylactic treatment. The Respiratory Protection Programme should be fully implemented to help reduce the risk of TB among health care workers in Sabah. PMID:14670342

  13. Keeping competition fair for health insurance: how the Irish beat back risk-rated policies.

    PubMed Central

    Light, D W

    1998-01-01

    OBJECTIVES: This paper describes how Ireland created a level playing field for competition in health insurance, the strategies of a major insurer to introduce risk-rated policies that would segment the market, the successful campaign to block these policies, and the policy implications of the European Union requirement of competition in health insurance. METHODS: Policy documents, interviews, and press reports were analyzed. RESULTS: The minister of health forced the commercial insurer to withdraw its policies and replace them with community-rated policies. CONCLUSIONS: Because it is easier and more profitable for insurers to engage in risk selection than to become more efficient, beneficial competition in health insurance markets is extremely difficult to create. Carefully drawn rules and monitoring are required to overcome inherent causes of market failure. The current enthusiasm for saving money through competitive schemes in health insurance seems likely to produce higher costs and greater inequality. PMID:9585738

    In this article the implications of a biopsychosocial model of adolescent health promotion for the delivery of relevant services in the schools are examined. Adolescent health status is reviewed and is found, despite existing efforts for health promotion and risk reduction, to be in need of substantial improvement. For this to happen, having an early and sustained positive impact on the health trajectory of children is essential; further school-based and school-linked curricular efforts for health promotion are a necessary feature of a successful strategy for adolescent health promotion. In fact, this approach brings to life the social contract between pediatricians and the public to apply the biopsychosocial model at both clinical and societal levels. Curricula serve as the glue that binds diverse health-related concerns and findings emerging from health research into a coordinated, thorough, and detailed strategy and set of actions for school-based and school-linked health promotion efforts. School-linked health programs are consistent with a biopsychosocial perspective, from which the school is best viewed as a health-promoting environment, centered in concepts and practices outlined in and conveyed through the curriculum and associated instructional practices and delivery systems. Many benefits can result from pediatricians and other medical professionals taking a renewed, prominent role in comprehensive school-based and school-linked health promotion efforts, beginning in the early grades, when the trajectory of adolescent health is strongly set into motion.

    Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people’s response and acceptance of related policies. Therefore, understanding people’ perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish levels and associations between perceived pollution and health risk perception among slum residents. A cross-sectional study of 5,317 individuals aged 35+ years was conducted in two slums of Nairobi. Association of perceived score and individual characteristics was assessed using linear regression. Spatial variation in the perceived levels was determined through hot spot analysis using ArcGIS. The average perceived air pollution level was higher among residents in Viwandani compared to those in Korogocho. Perceived air pollution level was positively associated with perceived health risks. The majority of respondents were exposed to air pollution in their place of work with 66% exposed to at least two sources of air pollution. Less than 20% of the respondents in both areas mentioned sources related to indoor pollution. The perceived air pollution level and related health risks in the study community were lowamong the residents indicating the need for promoting awareness on air pollution sources and related health risks.

    2015-09-01

    Mental health problems often go undiagnosed or unaddressed until a crisis or extreme event brings the problem to the forefront. Youth are particularly at risk for lack of identification and treatment in regard to mental health issues. This article describes an advanced nursing practice mental health initiative for at-risk teenage girls based on Hildegard Peplau's nursing theory, group process, and healing through holistic health approaches. A support group, RICHES, was developed with focus on core components of relationships, identity, communication, health, esteem, and support. The acronym RICHES was chosen as the name of the support group. Selected themes and issues addressed in this school-based support group are illustrated in case vignettes. Through a collaborative approach with the community and school, this practice initiative presents a unique healing process that extends knowledge in the realm of intervention with at-risk teenage girls. Further research is needed on the efficacy of support groups to modify risk factors and to address goals for primary prevention in at-risk teenage girls. PMID:25549962

    OBJECTIVE: To develop and test risk-adjustment outcome models in publicly funded mental health outpatient settings. We developed prospective risk models that used demographic and diagnostic variables; client-reported functioning, satisfaction, and quality of life; and case manager clinical ratings to predict subsequent client functional status, health-related quality of life, and satisfaction with services. DATA SOURCES/STUDY SETTING: Data collected from 289 adult clients at five- and ten-month intervals, from six community mental health agencies in Washington state located primarily in suburban and rural areas. Data sources included client self-report, case manager ratings, and management information system data. STUDY DESIGN: Model specifications were tested using prospective linear regression analyses. Models were validated in a separate sample and comparative agency performance examined. PRINCIPAL FINDINGS: Presence of severe diagnoses, substance abuse, client age, and baseline functional status and quality of life were predictive of mental health outcomes. Unadjusted versus risk-adjusted scores resulted in differently ranked agency performance. CONCLUSIONS: Risk-adjusted functional status and patient satisfaction outcome models can be developed for public mental health outpatient programs. Research is needed to improve the predictive accuracy of the outcome models developed in this study, and to develop techniques for use in applied settings. The finding that risk adjustment changes comparative agency performance has important consequences for quality monitoring and improvement. Issues in public mental health risk adjustment are discussed, including static versus dynamic risk models, utilization versus outcome models, choice and timing of measures, and access and quality improvement incentives.

    Objectives Antineoplastic drugs are known reproductive and developmental toxicants. Our objective was to review the existing literature of reproductive health risks to workers who handle antineoplastic drugs. Methods A structured literature review of 18 peer-reviewed, English language publications of occupational exposure and reproductive outcomes was performed. Results While effect sizes varied with study size and population, occupational exposure to antineoplastic drugs appears to raise the risk of both congenital malformations and miscarriage. Studies of infertility and time-to-pregnancy also suggested an increased risk for sub-fertility. Conclusions Antineoplastic drugs are highly toxic in patients receiving treatment and adverse reproductive effects have been well documented in these patients. Healthcare workers with chronic, low level occupational exposure to these drugs also appear to have an increased risk of adverse reproductive outcomes. Additional precautions to prevent exposure should be considered. PMID:25153300

    2015-02-01

    Late bedtimes in adolescence may be a serious risk factor for later poor health and functional outcomes. The current study sought to extend existing cross sectional data by examining whether late bedtimes in adolescence predicts poor outcomes in young adulthood. Data from wave 2 (1996) and wave 3 (2001-2002) of the nationally representative sample of US youth (National Longitudinal Study of Adolescent Health) was used to examine the longitudinal relationship between late bedtime, and several risk behaviors and negative health outcomes following 3,843 adolescents into young adulthood. At wave 2 the mean age was 16 with 52.1% female. At wave 3 the mean age was 21.8. In cross sectional analyses, late bedtime was associated with 1.5 to over 3 times greater odds of involvement in risk behaviors and negative health outcomes, including emotional distress, suicidality, criminal and violent activity, and use of cigarettes, alcohol and illicit drugs. In longitudinal analyses, late bedtime assessed at wave 2 predicted a number of serious health outcomes at wave 3, with late bedtime in adolescence associated with around 1.5 greater odds of involvement in health jeopardizing behaviors such as criminal activity, alcohol abuse, cigarette use, illicit drug use and emotional distress in young adulthood. There was also a dose effect, such that the later the bedtime in adolescence, the greater the risk of involvement in risk behaviors in young adulthood. This research suggests that late bedtime in adolescence predicts multiple serious risk behaviors and health outcomes in young adulthood. PMID:24599733

    Coronary artery disease (CAD) often leads to myocardial infarction, which may be fatal. Risk factors can be used to predict CAD, which may subsequently lead to prevention or early intervention. Patient data such as co-morbidities, medication history, social history and family history are required to determine the risk factors for a disease. However, risk factor data are usually embedded in unstructured clinical narratives if the data is not collected specifically for risk assessment purposes. Clinical text mining can be used to extract data related to risk factors from unstructured clinical notes. This study presents methods to extract Framingham risk factors from unstructured electronic health records using clinical text mining and to calculate 10-year coronary artery disease risk scores in a cohort of diabetic patients. We developed a rule-based system to extract risk factors: age, gender, total cholesterol, HDL-C, blood pressure, diabetes history and smoking history. The results showed that the output from the text mining system was reliable, but there was a significant amount of missing data to calculate the Framingham risk score. A systematic approach for understanding missing data was followed by implementation of imputation strategies. An analysis of the 10-year Framingham risk scores for coronary artery disease in this cohort has shown that the majority of the diabetic patients are at moderate risk of CAD. PMID:26319542

    Health problems of gold miners who worked underground include decreased life expectancy; increased frequency of cancer of the trachea, bronchus, lung, stomach, and liver; increased frequency of pulmonary tuberculosis (PTB), silicosis, and pleural diseases; increased frequency of insect-borne diseases, such as malaria and dengue fever; noise-induced hearing loss; increased prevalence of certain bacterial and viral diseases; and diseases of the blood, skin, and musculoskeletal system. These problems are briefly documented in gold miners from Australia, North America, South America, and Africa. In general, HIV infection or excessive alcohol and tobacco consumption tended to exacerbate existing health problems. Miners who used elemental mercury to amalgamate and extract gold were heavily contaminated with mercury. Among individuals exposed occupationally, concentrations of mercury in their air, fish diet, hair, urine, blood, and other tissues significantly exceeded all criteria proposed by various national and international regulatory agencies for protection of human health. However, large-scale epidemiological evidence of severe mercury-associated health problems in this cohort was not demonstrable.

  13. From Cancer to Diarrhea: The Moving Target of Public Concern about Environmental Health Risks

    PubMed Central

    Morrone, Michele

    2011-01-01

    Public concern about the environment can be unpredictable because it is influenced by numerous factors. Environmental health issues often emerge as important because the public is worried about their health especially when it comes to cancer. Public fear of cancer from environmental exposures is reinforced by many of the US regulations that set pollutant limits based on reducing the risk of cancers rather than other health outcomes. While fear of cancer will never dissipate, recent foodborne outbreaks are contributing to raising public awareness of the health effects from microbes. This paper adds to the dialogue about the challenges of enhancing public understanding of environmental health issues. Internal factors, such as worry, that contribute to public outrage are sometimes more important than external factors such as the media. In addition, relying on the media to inform the public about imminent public health risks may be an ineffective approach to enhancing understanding. In the end, scientists and risk communicators are forced to compete with politicians who are often very effective at manipulating public understanding of risk. PMID:22174587

    2011-10-04

    Industrialized societies which continue to use fossil fuel energy sources are considering adoption of Carbon Capture and Storage (CCS) technology to meet carbon emission reduction targets. Deep geological storage of CO2 onshore faces opposition regarding potential health effects of CO2 leakage from storage sites. There is no experience of commercial scale CCS with which to verify predicted risks of engineered storage failure. Studying risk from natural CO2 seeps can guide assessment of potential health risks from leaking onshore CO2 stores. Italy and Sicily are regions of intense natural CO2 degassing from surface seeps. These seeps exhibit a variety of expressions, characteristics (e.g., temperature/ flux), and location environments. Here we quantify historical fatalities from CO2 poisoning using a database of 286 natural CO2 seeps in Italy and Sicily. We find that risk of human death is strongly influenced by seep surface expression, local conditions (e.g., topography and wind speed), CO2 flux, and human behavior. Risk of accidental human death from these CO2 seeps is calculated to be 10-8 year-1 to the exposed population. This value is significantly lower than that of many socially accepted risks. Seepage from future storage sites is modeled to be less than Italian natural flux rates. With appropriate hazard management, health risks from unplanned seepage at onshore storage sites can be adequately minimized.

    We assessed health risks related to Arsenic (As) in contaminated drinking water in Hanam, applying the Australian Environmental Health Risk Assessment Framework, which promotes stakeholder involvement in risk assessments. As concentrations in 300 tube-well water samples, before and after filtration, were analyzed and the water consumption levels in 150 households were estimated. Skin cancer risk was characterized using Cancer Slope Factor index and lifetime average daily dose with a probabilistic approach. The results showed that arsenic concentrations in tube-well water ranged from 8–579 ppb (mean 301 ppb) before filtration and current sand filters used by the households did not meet the standard for As removal. Arsenic daily consumption of 40% of the adults exceeded the level of TDI (Tolerable Daily Intake) at 1 µg/kg/day. The average skin cancer risk in adults due to consuming filtered tube-well water for drinking purpose were 25.3 × 10?5 (using only well water) and 7.6 × 10?5 (using both well and rain water). The skin cancer risk would be 11.5 times higher if the water was not filtered. Improvement of filtration measures or the replacement of the current drinking water sources to minimize the health risks to the local population is urgently needed. PMID:25062276

    Female genital mutilation/cutting (FGM/C) is a traditional practice originating in Africa. Its worst forms cause irreparable harm to girls and women and have no medical justification. Based on a literature review of global responses to FGM/C and conversations with Australian women who migrated from FGM/C practicing countries, this paper provides some background on FGM/C and its epidemiology, outlining its prevalence, types, and health risks and complications for women and girls. It discusses risk-prevention strategies, first, for health practitioners in identifying, screening, and supporting women affected by FGM/C and, second, for welfare and social workers and health care professionals to identify, work with, and prevent girls from being cut. Consistent with international trends in addressing the risks of FGM/C, the paper suggests practice responses for coordinated responses between professionals, communities from practicing countries, and governments of different countries.

    The goal of environmental restoration and waste management activities is to reduce public health risks or to delay risks to the future when new technology will be available for improved cleanup solutions. Actions to remediate the wastes on the Hanford Site will entail risks to workers, the public, and the environment that do not currently exist. In some circumstances, remediation activities will create new exposure pathways that are not present without cleanup activities. In addition, cleanup actions will redistribute existing health risks over time and space, and will likely shift health risks to cleanup workers in the short term. This report describes an approach to occupational risk assessment based on the Hanford Strategic Analysis Study and illustrates the approach by comparing worker risks for two options for remediation of N/K fuels, a subcategory of unprocessed irradiated fuels at Hanford.

    The paper presents the results of geochemical investigations carried out in the city of Prague. Czech Republic, between the years 1994-1997, by the Czech Geological Institute, National Institute of Public Health and Hygiene Stations of Prague. Exposure assessment for children as the most sensitive population, based on soil ingestion pathway, indicates that lead is the major pollutant of concern, especially in the central regions of the city. Direct exposure assessment was done by analyzing blood and urine samples collected from children aged 3-6 years. Blood lead levels were the only biomarker significantly higher as compared to the control group (32.1 +/- 17.4 microg/l, 25.1 +/- 15.4 microg/l). This pilot study supports the establishment of a new sub-system within the already existing System of Monitoring the Environmental Impact on Population Health of the Czech Republic. PMID:11764850

    Inland southern California is a region of public health concern, especially for children, given the area’s perennially poor air quality and increasing sources of local pollution. One elementary school specifically is located only a few hundred yards from the San Bernardino Railyard, one of the busiest goods movement facilities in California, potentially increasing respiratory problems. Through ENRRICH (Environmental Railyard Research Impacting Community Health) Project, we assessed association of proximity to a major freight railyard on adverse respiratory health in schoolchildren. Respiratory screening was provided for children at two elementary schools: one near the railyard and a socio-demographically matched comparison school 7 miles away. Screening included testing for airway inflammation (FeNO), lung function (peak expiratory flow, PEF) and parent reported respiratory symptoms. Parental questionnaires collected additional information. Log-binomial and linear regression assessed associations. Children attending school near the railyard were more likely to exhibit airway obstruction with higher prevalence of abnormal PEF (<80 %): prevalence ratio (PR) = 1.59 (95 % CI 1.19–2.12). The association with inflammation was less clear. Children at the exposure school, who had lived 6 months or longer at their current address (vs. all children at that school) were more likely to have values suggesting inflammation (FeNO > 20 ppb) (PR = 1.44, 95 % CI 1.02–2.02) and present with a trend for increased adverse respiratory symptoms. Children attending school near the railyard were significantly more likely to display respiratory health challenges. Ideally these low-income, low resource communities should be supported to implement sustainable intervention strategies to promote an environment where children can live healthier and thrive.

    The Risk of Crew Adverse Health Event Due to Altered Immune Response is identified by the National Aeronautics and Space Administration (NASA) Human Research Program (HRP) as a recognized risk to human health and performance in space. The HRP Program Requirements Document (PRD) defines these risks. This Evidence Report provides a summary of the evidence that has been used to identify and characterize this risk. It is known that human immune function is altered in- and post-flight, but it is unclear at present if such alterations lead to increased susceptibility to disease. Reactivation of latent viruses has been documented in crewmembers, although this reactivation has not been directly correlated with immune changes or with observed diseases. As described in this report, further research is required to better characterize the relationships between altered immune response and susceptibility to disease during and after spaceflight. This is particularly important for future deep-space exploration missions.

    Research suggests that individual breast cancer risk assessment may improve adherence to recommended screening and prevention guidelines, thereby decreasing morbidity and mortality. Further research on the use of risk assessment models in underserved minority populations is critical to informing national public health efforts to eliminate breast cancer disparities. However, implementing individual breast cancer risk assessment in underserved patient populations raises particular ethical issues that require further examination. After reviewing these issues, we will discuss how empirical bioethics research can be integrated with health disparities research to inform the translation of research findings. Our in-progress National Cancer Institute (NCI) funded study, How Do Underserved Minority Women Think About Breast Cancer?, conducted in the context of a larger study on individual breast cancer risk assessment, is presented as a model.

    Geue, Claudia; Lorgelly, Paula; Lewsey, James; Hart, Carole; Briggs, Andrew

    2015-01-01

    Background It is important for health policy and expenditure projections to understand the relationship between age, death and expenditure on health care (HC). Research has shown that older age groups incur lower hospital costs than previously anticipated and that remaining time to death (TTD) was a much stronger indicator for expenditure than age. How health behaviour or risk factors impact on HC utilisation and costs at the end of life is relatively unknown. Smoking and Body Mass Index (BMI) have featured most prominently and mixed findings exist as to the exact nature of this association. Methods This paper considers the relationship between TTD, age and expenditure for inpatient care in the last 12 quarters of life; and introduces measures of health status and risks. A longitudinal dataset covering 35 years is utilised, including baseline survey data linked to hospital and death records. The effect of age, TTD and health indicators on expenditure for inpatient care is estimated using a two-part model. Results As individuals approach death costs increase. This effect is highly significant (p<0.01) from the last until the 8th quarter before death and influenced by age. Statistically significant effects on costs were found for: smoking status, systolic blood pressure and lung function (FEV1). On average, smokers incurred lower quarterly costs in their last 12 quarters of life than non-smokers (~7%). Participants’ BMI at baseline did show a negative association with probability of HC utilisation however this effect disappeared when costs were estimated. Conclusions Health risk measures obtained at baseline provide a good indication of individuals’ probability of needing medical attention later in life and incurring costs, despite the small size of the effect. Utilising a linked dataset, where such measures are available can add substantially to our ability to explain the relationship between TTD and costs. PMID:25746728

    Background: There is a recognized need to improve the application of epidemiologic data in human health risk assessment especially for understanding and characterizing risks from environmental and occupational exposures. Although there is uncertainty associated with the results of most epidemiologic studies, techniques exist to characterize uncertainty that can be applied to improve weight-of-evidence evaluations and risk characterization efforts. Methods: This report derives from a Health and Environmental Sciences Institute (HESI) workshop held in Research Triangle Park, North Carolina, to discuss the utility of using epidemiologic data in risk assessments, including the use of advanced analytic methods to address sources of uncertainty. Epidemiologists, toxicologists, and risk assessors from academia, government, and industry convened to discuss uncertainty, exposure assessment, and application of analytic methods to address these challenges. Synthesis: Several recommendations emerged to help improve the utility of epidemiologic data in risk assessment. For example, improved characterization of uncertainty is needed to allow risk assessors to quantitatively assess potential sources of bias. Data are needed to facilitate this quantitative analysis, and interdisciplinary approaches will help ensure that sufficient information is collected for a thorough uncertainty evaluation. Advanced analytic methods and tools such as directed acyclic graphs (DAGs) and Bayesian statistical techniques can provide important insights and support interpretation of epidemiologic data. Conclusions: The discussions and recommendations from this workshop demonstrate that there are practical steps that the scientific community can adopt to strengthen epidemiologic data for decision making.

  16. A risk-adjusted approach to comparing the return on investment in health care programs.

    The league table approach to rank ordering health care programs according to the incremental cost-effectiveness ratio is a common method to guide policy makers in setting priorities for resource allocation. In the presence of uncertainty, however, ranking programs is complicated by the degree of variability associated with each program. Confidence intervals for cost-effectiveness ratios may be overlapping. Moreover, confidence intervals may include negative ratios and the interpretation of negative cost-effectiveness ratios is ambiguous. We suggest to rank mutually exclusive health care programs according to their rate of return which is defined as the net monetary benefit over the costs of the program. However, how does a program with a higher expected return but higher uncertainty compare to a program with a lower expected return but lower risk? In the present paper we propose a risk-adjusted measure to compare the return on investment in health care programs. Financing a health care program is treated as an investment in a risky asset. The risky asset is combined with a risk-free asset in order to construct a combined portfolio. The weights attributed to the risk-free and risky assets are chosen in such a manner that all programs under consideration exhibit the same degree of uncertainty. We can then compare the performance of the individual programs by constructing a risk-adjusted league table of expected returns. PMID:15277778

    In order to evaluate the potential adverse health effects of odor emissions from wastewater pump stations (WWPSs) to human, a health risk assessment was performed to study the odors emitted from an urban WWPS in a residential area, Tianjin (in North China). First, 15 types of volatile organic compounds in the WWPS were collected and analyzed using gas chromatography-mass spectrometry. Next, Monte Carlo probabilistic modeling was applied to evaluate the potential health effects of four odors (chlorobenzene, dichloromethane, hydrogen sulfide, and carbon disulfide), which had higher concentrations. The results revealed that the 95th percentile of the total non-carcinogenic risk was approximately 1.73, which poses a threat to human health. In addition, hydrogen sulfide had the highest non-carcinogenic risk value of the four; the hazard quotient of hydrogen sulfide was estimated to be 1.60 at the 95th percentile, higher than the upper confidence limit (1.0). The 95th percentile of the carcinogenic risk was approximately 5.47E-08, much lower than the maximum acceptable level (1.0E-06). Finally, the influence of the input variables on the output was evaluated using sensitivity analysis, and contaminant concentration, reference concentration, and inhalation unit risk were the most influential variables.

    This paper is an attempt to place some of the health risks in a modern society in perspective. Apparently objective assessments of health risks are often highly value-laden, and incorporate many social assumptions. Cancer is often considered by the public to be more dangerous than many other diseases. Cancer research workers may also be emotional in their reactions to new results, and this can easily destroy their credibility. The public often seem to be more concerned with industrial carcinogens, which are probably responsible for less morbidity and mortality than an unhealthy life style. The importance of a critical scientific attitude tempered by concern for individuals is emphasized.

    This study determined the total and speciated arsenic (As) concentrations and other health-related water quality parameters for unraveling the health risk of As from drinking water to humans. Groundwater samples (n = 62) were collected from three previously unexplored rural areas (Chichawatni, Vehari, Rahim Yar Khan) of Punjab in Pakistan. The mean and median As concentrations in groundwater were 37.9 and 12.7 µg·L(-1) (range = 1.5-201 µg·L(-1)). Fifty three percent groundwater samples showed higher As value than WHO safe limit of 10 µg·L(-1). Speciation of As in groundwater samples (n = 13) showed the presence of inorganic As only; arsenite (As(III)) constituted 13%-67% of total As and arsenate (As(V)) ranged from 33% to 100%. For As health risk assessment, the hazard quotient and cancer risk values were 11-18 and 46-600 times higher than the recommended values of US-EPA (i.e., 1.00 and 10(-6), respectively). In addition to As, various water quality parameters (e.g., electrical conductivity, Na, Ca, Cl(-), NO?(-), SO?(2-), Fe, Mn, Pb) also enhanced the health risk. The results show that consumption of As-contaminated groundwater poses an emerging health threat to the communities in the study area, and hence needs urgent remedial and management measures.

    The electronic health record represents a major change in healthcare delivery, either for health professionals and health institutions, either for patients. In this essay we will mainly focus on its consequences regarding patient safety and medical liability. In this particular domain the electronic health record has dual effects: on one side prevents medical errors and, in this sense, promotes patient safety and protects the doctor from lawsuits; but, on the other side, when not used properly, it may also generate other kind of errors, potentially threatening patient safety and, therefore, increasing the risk of juridical liability for the physician. This paper intends to underline the main human errors, technologic mistakes and medical faults that may occur while using the electronic health record and the ways to overcome them, also explaining how the electronic health record may be used in court during a judicial proceeding.

    Appling, J.W.

    1994-12-31

    Conservative approaches to human health or ecological risk assessment often result in evaluations that indicate a risk at metal concentrations near or below background levels. This presents a complex dilemma to regulators, responsible parties, and the public: How can risk be more realistically estimated so that the public is not unnecessarily alarmed into thinking normal exposures pose abnormal risk, and site remediation can be responsible yet cost-effective? One answer is using-ecological and human health studies together to improve the quality of both types of assessments. Mammalian herbivores and roving children are good spatial and temporal integrators of exposure; biomarkers or Monte Carlo-based models of exposure to herbivores can support realistic estimates of exposure to children. Reduced bioavailability of metals in soils at mining sites is well recognized for many metals and is amenable to study in ecological species; such studies reduce the overestimate of risk to humans through direct contact or exposure via the food chain. Recent and current human health studies of lead and arsenic bioavailability also support ecological assessments. Mixtures of metals pose special challenges because of the potential for antagonistic, additive, or synergistic effects with respect to bioavailability, absorption, distribution, excretion, toxic effects and nutritional or physiological essentiality. Combining results from pharmacokinetic, mechanistic, and environmental studies of mixtures enhances the predictive abilities of risk assessments.

    Understanding the exposure risks of trace metals in contamination soils and apportioning their sources are the basic preconditions for soil pollution prevention and control. In this study, a detailed investigation was conducted to assess the health risks of trace metals in surface soils of Beijing which is one of the most populated cities in the world and to apportion their potential sources. The data set of metals for 12 elements in 240 soil samples was collected. Pollution index and enrichment factor were used to identify the general contamination characteristic of soil metals. The probabilistic risk model was employed for health risk assessment, and a chemometrics technique, multivariate curve resolution-weighted alternating least squares (MCR-WALS), was applied to apportion sources. Results suggested that the soils in Beijing metropolitan region were contaminated by Hg, Cd, Cu, As, and Pb in varying degree, lying in the moderate pollution level. As a whole, the health risks posed by soil metals were acceptable or close to tolerable. Comparatively speaking, children and adult females were the relatively vulnerable populations for the non-carcinogenic and carcinogenic risks, respectively. Atmospheric deposition, fertilizers and agrochemicals, and natural source were apportioned as the potential sources determining the contents of trace metals in soils of Beijing area with contributions of 15.5%-16.4%, 5.9%-7.7% and 76.0%-78.6%, respectively.

    Poor nutrition and insufficient physical activity contribute to high rates of obesity. Prevalence, intention to change and co-occurrence of four health risk behaviours (inadequate fruit and vegetables, excessive dietary fat, excessive sugary beverages and inadequate physical activity in comparison to public health recommendations) were investigated in an Australian population of working adults. Participants (n=105) completed sociodemographic and stage of change questionnaires. A subsample (n=40) were assessed twice to estimate test-retest repeatability. In the full sample, 73% were female, mean age was 33.8 years and mean BMI was 23.8 kg/m(2). Eighty-seven percent of participants consumed inadequate fruit and vegetables, 43% had excessive dietary fat, 42% had excessive sugary beverages and 29% had inadequate physical activity. The proportions intending to change each behaviour were 57%, 25%, 18% and 24%, respectively. Two-thirds exhibited multiple risk behaviours and 38% intended to change multiple risk behaviours. Fruit and vegetables and dietary fat were the most commonly paired risk behaviours (39%) and the pair most intended to change (19%). Occurrence of multiple risk behaviours was associated with being male (OR 3.10, 95% CI 1.06-9.03) or overweight/obese (OR 2.66, 95% CI 1.02-6.93). Targeting two risk behaviours, particularly fruit and vegetables and dietary fat, may be appropriate when designing health promotion programs in working populations. PMID:23962404

    Few studies have examined the context of a wide range of risk behaviors among emerging adults (ages 18-25 years), approximately half of whom in the USA enroll in post-secondary educational institutions. The objective of this research was to examine behavioral patterning in weight behaviors (diet and physical activity), substance use, sexual behavior, stress, and sleep among undergraduate students. Health survey data were collected among undergraduates attending a large, public US university (n = 2,026). Latent class analysis was used to identify homogeneous, mutually exclusive "classes" (patterns) of ten leading risk behaviors. Resulting classes differed for males and females. Female classes were defined as: (1) poor lifestyle (diet, physical activity, sleep), yet low-risk behaviors (e.g., smoking, binge drinking, sexual risk, drunk driving; 40.0% of females), (2) high risk (high substance use, intoxicated sex, drunk driving, poor diet, inadequate sleep) (24.3%), (3) moderate lifestyle, few risk behaviors (20.4%), (4) "health conscious" (favorable diet/physical activity with some unhealthy weight control; 15.4%). Male classes were: (1) poor lifestyle, low risk (with notably high stress, insufficient sleep, 9.2% of males), (2) high risk (33.6% of males, similar to class 2 in females), (3) moderate lifestyle, low risk (51.0%), and (4) "classic jocks" (high physical activity, binge drinking, 6.2%). To our knowledge, this is among the first research to examine complex lifestyle patterning among college youth, particularly with emphasis on the role of weight-related behaviors. These findings have important implications for targeting much needed health promotion strategies among emerging adults and college youth. PMID:19499339

  9. Nutrition Can Modulate the Toxicity of Environmental Pollutants: Implications in Risk Assessment and Human Health

    Background: The paradigm of human risk assessment includes many variables that must be viewed collectively in order to improve human health and prevent chronic disease. The pathology of chronic diseases is complex, however, and may be influenced by exposure to environmental pollu-tants, a sedentary lifestyle, and poor dietary habits. Much of the emerging evidence suggests that nutrition can modulate the toxicity of environmental pollutants, which may alter human risks associated with toxicant exposures. Objectives: In this commentary, we discuss the basis for recommending that nutrition be considered a critical variable in disease outcomes associated with exposure to environmental pollutants, thus establishing the importance of incorporating nutrition within the context of cumulative risk assessment. Discussion: A convincing body of research indicates that nutrition is a modulator of vulnerability to environmental insults; thus, it is timely to consider nutrition as a vital component of human risk assessment. Nutrition may serve as either an agonist or an antagonist (e.g., high-fat foods or foods rich in antioxidants, respectively) of the health impacts associated with exposure to environmental pollutants. Dietary practices and food choices may help explain the large variability observed in human risk assessment. Conclusion: We recommend that nutrition and dietary practices be incorporated into future environmental research and the development of risk assessment paradigms. Healthful nutrition interventions might be a powerful approach to reduce disease risks associated with many environmental toxic insults and should be considered a variable within the context of cumulative risk assessment and, where appropriate, a potential tool for subsequent risk reduction.

    The Bandar Bushehr, Iran earthquake of April 9, 2013 gravely illustrates how disaster-prone areas of the world are compounding their risk of disaster and major public health emergencies when there is a geographical convergence of natural and technological hazards. Scientists must emphasize to policy makers that ever-increasing regional industrialization and the broader introduction of nuclear facilities, especially in the Middle East, must parallel sound prevention and community-level public health preparedness planning.

    Diabetes is a national health problem, and the burden of the disease and its consequences particularly affect Hispanics. While social determinants of health models have improved our conceptualization of how certain contexts and environments influence an individual's ability to make healthy choices, a structural violence framework transcends traditional uni-dimensional analysis. Thus, a structural violence approach is capable of revealing dynamics of social practices that operate across multiple dimensions of people's lives in ways that may not immediately appear related to health. Working with a Hispanic immigrant community in Albuquerque, New Mexico, we demonstrate how structural forces simultaneously directly inhibit access to appropriate healthcare services and create fear among immigrants, acting to further undermine health and nurture disparity. Although fear is not normally directly associated with diabetes health outcomes, in the community where we conducted this study participant narratives discussed fear and health as interconnected.

    There are presented results of the calculation of carcinogenic and non-carcinogenic risks due to the impact of chemical air pollutants for the human health of a large industrial city. Maximal levels of carcinogenic hazards under inhalation route of substances from the air were established to be noted on gasoline, manganese, sulfur dioxide, copper oxide, formaldehyde. In the formation of carcinogenic risk the greatest contribution is made by chromium, gasoline, formaldehyde, benzol. The risk of non-carcinogenic and carcinogenic effects for the population of the city continues to remain to be high, that requires the development and implementation of planned recreational measures.

    A substantial burden of communicable and non-communicable diseases in the developing countries is attributable to environmental risk factors. WHO estimates that the environmental factors are responsible for an estimated 24 per cent of the global burden of disease in terms of healthy life years lost and 23 per cent of all deaths; children being the worst sufferers. Given that the environment is linked with most of the Millennium Development Goals (MDGs), without proper attention to the environmental risk factors and their management, it will be difficult to achieve many MDGs by 2015. The impact of environmental degradation on health may continue well into the future and the situation in fact, is likely to get worse. In order to address this challenge, two facts are worth noting. First, that much of the environmental disease burden is attributable to a few critical risk factors which include unsafe water and sanitation, exposure to indoor smoke from cooking fuel, outdoor air pollution, exposure to chemicals such as arsenic, and climate change. Second, that environment and health aspects must become, as a matter of urgency, a national priority, both in terms of policy and resources allocation. To meet the challenge of health and environment now and in the future, the following strategic approaches must be considered which include conducting environmental and health impact assessments; strengthening national environmental health policy and infrastructure; fostering inter-sectoral co-ordination and partnerships; mobilizing public participation; and enhancing the leadership role of health in advocacy, stewardship and capacity building.

    The clean-shave haircut known locally as the chiskop is rare among females but popular with black South African men, who are also predisposed to folliculitis keloidalis nuchae (FKN) (keloids on the back of the head). During a previous study, participants described an unexpected symptom of haircut-associated bleeding. As this is not a widely recognised entity, we conducted the present study at an HIV clinic servicing the same population, with the objective of comparing the prevalences of haircut-associated bleeding and FKN in 390 HIV-positive subjects with published data for Langa (Western Cape, South Africa). The results for HIV-positive participants were similar to the population data, but in both groups the prevalence of haircut-associated bleeding (24.5% v. 32%; p=0.17) was much higher than that of FKN (10.2% v. 10.5%), suggesting that the hairstyle increases the risk of bleeding even in people with healthy scalps without folliculitis. This study does not (and was not intended to) prove a higher HIV prevalence in chiskop wearers or in FKN sufferers, but it confirms a history of haircut-associated bleeding in at least a quarter of our male study participants. The risk of transmission of blood-borne infection via haircuts is likely to be low, but requires formal quantification. Public education on adequate sterilisation of barber equipment between haircuts and promotion of individual hair-clipper ownership for chiskop clients should not be delayed. Depilatory creams formulated for African hair offer a non-mechanical means of achieving clean-shave hairstyles. PMID:23802217

    There is growing evidence that projected climate change has the potential to significantly affect public health. In the UK, much of this impact is likely to arise by amplifying existing risks related to heat exposure, flooding, and chemical and biological contamination in buildings. Identifying the health effects of climate change on the indoor environment, and risks and opportunities related to climate change adaptation and mitigation, can help protect public health. We explored a range of health risks in the domestic indoor environment related to climate change, as well as the potential health benefits and unintended harmful effects of climate change mitigation and adaptation policies in the UK housing sector. We reviewed relevant scientific literature, focusing on housing-related health effects in the UK likely to arise through either direct or indirect mechanisms of climate change or mitigation and adaptation measures in the built environment. We considered the following categories of effect: (i) indoor temperatures, (ii) indoor air quality, (iii) indoor allergens and infections, and (iv) flood damage and water contamination. Climate change may exacerbate health risks and inequalities across these categories and in a variety of ways, if adequate adaptation measures are not taken. Certain changes to the indoor environment can affect indoor air quality or promote the growth and propagation of pathogenic organisms. Measures aimed at reducing greenhouse gas emissions have the potential for ancillary public health benefits including reductions in health burdens related heat and cold, indoor exposure to air pollution derived from outdoor sources, and mould growth. However, increasing airtightness of dwellings in pursuit of energy efficiency could also have negative effects by increasing concentrations of pollutants (such as PM2.5, CO and radon) derived from indoor or ground sources, and biological contamination. These effects can largely be ameliorated by mechanical ventilation with heat recovery (MVHR) and air filtration, where such solution is feasible and when the system is properly installed, operated and maintained. Groups at high risk of these adverse health effects include the elderly (especially those living on their own), individuals with pre-existing illnesses, people living in overcrowded accommodation, and the socioeconomically deprived. A better understanding of how current and emerging building infrastructure design, construction, and materials may affect health in the context of climate change and mitigation and adaptation measures is needed in the UK and other high income countries. Long-term, energy efficient building design interventions, ensuring adequate ventilation, need to be promoted. PMID:26453820

  18. Long-Term Effects of Childhood Risk Factors on Cardiovascular Health During Adulthood

    The primary purpose of this article is to provide a broad overview of the research on the long-term effects of childhood risk factors on cardiovascular diseases (CVDs) during adulthood and to outline recommendations for prevention of CVDs based on evidence-based interventions (EBIs). CVDs are the leading cause of death and a major cause of disability in the United States and globally. Risk factors for CVDs are already identifiable in children and youth, and include both modifiable factors (e.g., unhealthy diet, physical inactivity, tobacco smoking), and factors that cannot be changed (e.g., age, heredity, sex). A fundamental issue has been the severity of the long-term effects of childhood risk factors (i.e., behavioral and intermediate risk factors) on subsequent cardiovascular health. It is clear from the empirical evidence that risk factors for CVDs can develop during childhood and adolescence. These risk factors in childhood have been linked to adverse health outcomes, including CVDs, during adulthood. The findings thus far suggest that, in order to be effective and reduce the risk of adulthood CVDs, intervention strategies should begin during childhood. The findings also underscore the importance of adopting a healthy lifestyle as early in life as possible. PMID:26312015

    The mission of NASA's Human Research Program (HRP) is to understand and reduce the risk to crew health and performance in exploration missions. The HRP addresses 27 specific risks by identifying and then filling gaps in understanding the risks and in the ability to disposition the risks. The primary bases for identifying gaps have been past experience and requirements definition. This approach has been very effective in identifying some important, relevant gaps, but may be inadequate for identifying gaps outside the past experience base. We are exploring the use of a gap taxonomy as a comprehensive, underlying conceptual framework that allows a more systematic identification of gaps. The taxonomy is based on these stages in medical care: prediction, prevention, detection/diagnosis, treatment, monitoring, rehabilitation, and lifetime surveillance. This gap taxonomy approach identifies new gaps in HRP health risks. Many of the new gaps suggest risk reduction approaches that are more cost effective than present approaches. A major benefit of the gap taxonomy approach is to identify new, economical approaches that reduce the likelihood and/or consequence of a risk.

    Aim: This study aims to investigate the general mental health situation, work-related stress and risk factors of health management trainees. Methods: This cross-sectional study was conducted on Health Management Musters students (N=96) in Canakkale Onsekiz Mart University Health Sciences Institute, May-June 2014. A total of 58 students who voluntarily participated in the study were reached (60.42%). Participants completed a 22-question sociodemographic survey form and a 12-item General Health Questionnaire in a face-to-face interview. Data were analyzed using the SPSS software version 20.0. Results: The average age of participants was 36.4±6.2 (Min:24-Max:62) years. Thirty five of the participants were female (60.3%), 23 were male (39.7%). The number of people using cigarettes and alcohol were 23 (39.7%) and 9 (15.8%) respectively. In our study group according to GHQ scale 32 people (55.2%) were in the group at risk of depression. Eighty-six percent of participants reported experiencing work stress. The most frequently reported sources of stress were superiors (56.8%), work itself (41.3%), and work colleagues (25.8%). There was no significant difference between those at risk of depression and those not at risk in terms of gender, marital status, educational level, age, work-related factors (daily work, computer use, duration of sitting at desk), sleep duration, presence of chronic disease, substance use (cigarettes, alcohol), regular exercise, regular meals, fast-food consumption, sufficient family time and vacations (p>0.05). Conclusions: Our study results indicated that majority of participants reported experiencing work stress with more than half at high risk of developing depression. The most reported risk factors were superiors, the work itself and colleagues in the present study. Psychosocial risk factors at work environment should be investigated in terms of psychological, sociological and ergonomics in more detail to reduce the risk of health management trainees experiencing work stress and mental health problems.
