This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between age and noise and their individual effects on hearing is complex, making it difficult to distinguish between noise-induced hearing loss and agerelated hearing loss at an individual level. This retrospective cohort study aimed to determine the decline in hearing sensitivity in noise-exposed mineworkers as opposed to non-noise-exposed mineworkers over time to evaluate the combined and individual contributions of noise exposure and age. A mixed effects regression analysis was applied to longitudinal audiological data from a group of mineworkers in South Africa. Four serial (annual) audiograms of 2,583 mineworkers were utilised. Data of a non-noise-exposed group (n=951) and a group exposed to underground noise (©Ø0́ʻ℗Æ85 dBA) (n=1632) were included. Results indicated that base values were significantly higher for the noise-exposed versus non-noise-exposed group, for the low-frequency average (LFA) of 0.5, 1 and 2 KHz (16.1 dB HL versus 11.1 dB HL), and high-frequency average (HFA) of 3, 4 and 6 KHz (25.7 dB HL versus 18.5 dB HL). These results may be indicative of previous noise damage in the noise-exposed group obtained before occupational noise limitations and personal hearing protection use were enforced through legislation in 2001. All year-to-year increases in mean hearing thresholds were statistically significant (p-values of

Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Medicine carried out a study mandated by Congress and sponsored by the Department of Veterans Affairs to provide an assessment of several issues related to noise-induced hearing loss and tinnitus associated with service in the Armed Forces since World War II. The resulting book, Noise and Military Service: Implications for Hearing Loss and Tinnitus, presents findings on the presence of hazardous noise in military settings, levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure on hearing, and the adequacy of military hearing conservation programs and audiometric testing. The book stresses the importance of conducting hearing tests (audiograms) at the beginning and end of military service for all military personnel and recommends several steps aimed at improving the military services' prevention of and surveillance for hearing loss and tinnitus. The book also identifies research needs, emphasizing topics specifically related to military service.

This book was released on 2016-10-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.

Download or read book Noise Induced Hearing Loss written by Colleen G. Le Prell and published by Springer Science & Business Media. This book was released on 2011-10-30 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances have the potential to impact how NIHL can be prevented and how our noise standards can be made more appropriate.

Download or read book Occupational Noise Exposure written by Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-02-19 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Occupational Safety and Health Act of 1970, Congress declared that its purpose was to assure, so far as possible, safe and healthful working conditions for every working man and woman and to preserve our human resources. In this Act, the National Institute for Occupational Safety and Health (NIOSH) is charged with recommending occupational safety and health standards and describing exposure concentrations that are safe for various periods of employment-including but not limited to concentrations at which no worker will suffer diminished health, functional capacity, or life expectancy as a result of his or her work experience. By means of criteria documents, NIOSH communicates these recommended standards to regulatory agencies (including the Occupational Safety and Health Administration [OSHA]) and to others in the occupational safety and health community. Criteria documents provide the scientific basis for new occupational safety and health standards. These documents generally contain a critical review of the scientific and technical information available on the prevalence of hazards, the existence of safety and health risks, and the adequacy of control methods. In addition to transmitting these documents to the Department of Labor, NIOSH also distributes them to health professionals in academic institutions, industry, organized labor, public interest groups, and other government agencies. In 1972, NIOSH published Criteria for a Recommended Standard: Occupational Exposure to Noise, which provided the basis for a recommended standard to reduce the risk of developing permanent hearing loss as a result of occupational noise exposure [NIOSH 1972]. NIOSH has now evaluated the latest scientific information and has revised some of its previous recommendations. The 1998 recommendations go beyond attempting to conserve hearing by focusing on preventing occupational noise-induced hearing loss (NIHL). This criteria document reevaluates and reaffirms the recommended exposure limit (REL) for occupational noise exposure established by the National Institute for Occupational Safety and Health (NIOSH) in 1972. The REL is 85 decibels, A-weighted, as an 8-hr time-weighted average (85 dBA as an 8-hr TWA). Exposures at or above this level are hazardous. By incorporating the 4000-Hz audiometric frequency into the definition of hearing impairment in the risk assessment, NIOSH has found an 8% excess risk of developing occupational noise-induced hearing loss (NIHL) during a 40-year lifetime exposure at the 85-dBA REL. NIOSH has also found that scientific evidence supports the use of a 3-dB exchange rate for the calculation of TWA exposures to noise. The recommendations in this document go beyond attempts to conserve hearing by focusing on prevention of occupational NIHL. For workers whose noise exposures equal or exceed 85 dBA, NIOSH recommends a hearing loss prevention program (HLPP) that includes exposure assessment, engineering and administrative controls, proper use of hearing protectors, audiometric evaluation, education and motivation, recordkeeping, and program audits and evaluations. Audiometric evaluation is an important component of an HLPP. To provide early identification of workers with increasing hearing loss, NIOSH has revised the criterion for significant threshold shift to an increase of 15 dB in the hearing threshold level (HTL) at 500, 1000, 2000, 3000, 4000, or 6000 Hz in either ear, as determined by two consecutive tests. To permit timely intervention and prevent further hearing losses in workers whose HTLs have increased because of occupational noise exposure, NIOSH no longer recommends age correction on individual audiograms.

Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. ​This handbook synthesizes and analyzes the growing knowledge base on life course health development (LCHD) from the prenatal period through emerging adulthood, with implications for clinical practice and public health. It presents LCHD as an innovative field with a sound theoretical framework for understanding wellness and disease from a lifespan perspective, replacing previous medical, biopsychosocial, and early genomic models of health. Interdisciplinary chapters discuss major health concerns (diabetes, obesity), important less-studied conditions (hearing, kidney health), and large-scale issues (nutrition, adversity) from a lifespan viewpoint. In addition, chapters address methodological approaches and challenges by analyzing existing measures, studies, and surveys. The book concludes with the editors’ research agenda that proposes priorities for future LCHD research and its application to health care practice and health policy. Topics featured in the Handbook include: The prenatal period and its effect on child obesity and metabolic outcomes. Pregnancy complications and their effect on women’s cardiovascular health. A multi-level approach for obesity prevention in children. Application of the LCHD framework to autism spectrum disorder. Socioeconomic disadvantage and its influence on health development across the lifespan. The importance of nutrition to optimal health development across the lifespan. The Handbook of Life Course Health Development is a must-have resource for researchers, clinicians/professionals, and graduate students in developmental psychology/science; maternal and child health; social work; health economics; educational policy and politics; and medical law as well as many interrelated subdisciplines in psychology, medicine, public health, mental health, education, social welfare, economics, sociology, and law.

Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Download or read book Late Life Depression written by Steven P. Roose and published by Oxford University Press. This book was released on 2004-07-15 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an aging world. Illnesses that are prevalent and cause significant morbidity and mortality in older people will consume an increasing share of health care resources. One such illness is depression. This illness has a particularly devastating impact in the elderly because it is often undiagnosed or inadequately treated. Depression not only has a profound impact on quality of life but it is associated with an increased risk of mortality from suicide and vascular disease. In fact for every medical illness studied, e.g. heart disease, diabetes, cancer, individuals who are depressed have a worse prognosis. Research has illuminated the physiological and behavioral effects of depression that accounts for these poor outcomes. The deleterious relationship between depression and other illnesses has changed the concept of late-life depression from a "psychiatric disorder" that is diagnosed and treated by a psychiatrist to a common and serious disorder that is the responsibility of all physicians who care for patients over the age of 60.This is the first volume devoted to the epidemiology, phenomenology, psychobiology, treatment and consequences of late-life depression. Although much has been written about depressive disorders, the focus has been primarily on the illness as experienced in younger adults. The effects of aging on the brain, the physiological and behavioral consequences of recurrent depression, and the impact of other diseases common in the elderly, make late-life depression a distinct entity. There is a compelling need for a separate research program, specialized treatments, and a book dedicated to this disorder. This book will be invaluable to psychiatrists, gerontologists, clinical psychologists, social workers, students, trainees, and others who care for individuals over the age of sixty.

Download or read book Occupational noise induced hearing loss written by Katijah Khoza-Shangase and published by AOSIS. This book was released on 2023-03-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the well-documented understanding of occupational noise-induced hearing loss (ONIHL) being a complex occupational health condition requiring the adoption of the complex interventions approach to management, challenges confronting hearing conservation programmes (HCPs) within the African context need clear characterisation and insightful deliberation. Guided by the systems theory, to be realistic about the implementation, monitoring, as well as evaluation of outcomes of HCPs within the African mining context, this book is a call for a paradigm shift in the assessment and management of ONIHL and HCPs in African mines. This book, Occupational Noise Induced Hearing Loss: An African Perspective, equips researchers involved in the management of ONIHL and implementation of HCPs with evidence that allows for contextually relevant best practices in mine settings, particularly those located in low-and-middle-income countries (LMICs). This best practice is multidisciplinary in nature and engages all stakeholders in all relevant sectors, with the goal of adopting a preventive audiology approach to ONIHL rather than the compensation-oriented approach that is currently prevailing. This book is a research-driven contribution to the occupational health and safety (OHS) space, with ONIHL as a focus case study, and it provides contemporary, contextually relevant, and responsive evidence related to ONIHL and HCPs in LMICs with a very specific focus on the South African context. This book expansively addresses all aspects of ONIHL and HCPs in one volume, with careful considerations of complexities and challenges to HCPs implementation, applicable specifically to LMICs, although useful globally. The book offers potential solutions and recommendations for all challenges identified, having carefully and deliberately engaged with local evidence, local context, and local policies and regulations to ensure an Afrocentric contribution to the world of evidence.

Download or read book Handbook of Socioeconomic Determinants of Occupational Health written by Töres Theorell and published by Springer. This book was released on 2020-08-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This anthology provides readers of scientific literature on socioeconomic factors and working conditions with the newest knowledge in this field. Since our world is subjected to constant change in accelerating speed, scientific reviews and updates are needed. Fortunately, research methodology in epidemiology, physiology, psychology and sociology is also developing rapidly and therefore the scientific community can provide politicians and policy makers with increasingly sophisticated and exact descriptions of societal factors in relation to work. The anthology starts in the macro level sphere – with international perspectives and reviews related to working conditions in relation to political change (the fall of the Soviet Union) gender, age, precarious employment, national economy and retirement. Two chapters relate to national policies and activities in international organizations. The second part of the book relates to the meso level sphere – with reviews on social patterns in distributions of psychosocial and physical risks at work in general as well as reviews on noise, shift work, under/overemployment, occupational physical activity, job intensity (which may be a particularly important problem in low income countries), digitization in modern work, climate change, childhood determinants of occupational health in adult years and theoretical models currently used in occupational epidemiology - demand/control, effort/reward, organizational justice, psychosocial safety climate, conflicts, bullying/harassment. This part of the book ends with two chapters on interventions (one chapter on the use of cultural interventions and one on interventions and their evaluation in general) and two chapters on financial aspects of poor/good work environments and evaluations of interventions. In the third part of the book the micro level is addressed. Here mechanisms translating working conditions into physiology are discussed. This starts in general theory relating basic theories regarding energy storage and release to psychosocial theory (extension of demand control theory). It also includes regeneration physiology, autonomic nervous system function, immunology and adverse behaviour.

Download or read book Preventive audiology written by Katijah Khoza-Shangase and published by AOSIS. This book was released on 2023-03-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an original scholarly book that introduces the concept of preventive audiology, with a specific focus on the African context, which is in line with the South African re-engineered primary healthcare strategy as well as the World Health Organisation’s approach. The book reflects on contextually relevant and responsive evidence-based perspectives, grounded in an African context on preventive audiology, in four major ear and hearing burdens of disease within the South African context: (1) early hearing detection and intervention, (2) middle ear pathologies, (3) ototoxicity, and (4) noise-induced hearing loss. The book represents innovative research, seen from both a South African and global perspective. It offers new discourse and argues for a paradigm shift in how audiology is theorised and performed, particularly in low-and-middle-income country contexts. The goal of this book is to motivate a paradigm shift in how the ear and hearing care is approached within this low-and-middle-income country context while arguing for Afrocentric best practice evidence that leads to next practice.

Download or read book Hearing Loss written by Tang-Chuan Wang and published by BoD – Books on Demand. This book was released on 2021-07-07 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auditory system is one of the finest structures in the human body. Although its anatomical structure is so small compared to other organs, without it, it would greatly affect a person’s basic life. Hearing loss, also known as hearing impairment, is a partial or total inability to hear. When people communicate with others, listening is always the first step. That is why Helen Keller once said, “Blindness separates people from things; deafness separates people from people.” To avoid the “epidemic” of hearing loss in the near future, it is necessary to promote early screening, change public attitudes toward noise, and wear hearing aids appropriately. Based on the contributions of many authors, whom I sincerely respect, this book incorporates updated developments as well as future perspectives in the ever-expanding field of hearing loss. This book can also serve as a reference for persons who are involved in this field whether they are clinicians, researchers, or patients.
