An analysis of biological theories and epidemiologic studies in cardiovascular diseases

Presentation of the epidemiologic concepts and methods appropriate to the study of chronic (mostly non-infectious) diseases and diseases of unknown etiology approaches and problems in descriptive, analytic, and experimental (controlled trials) epidemiology will be compared with those for the acute infectious diseases. The catalyst for a life course approach in epidemiology stemmed from the revival of interest in the role of early life factors in cardiovascular and other chronic diseases, 17 in particular the ecological and historical cohort studies used to explore the fetal origins hypothesis 18 according to this hypothesis, environmental exposures such as. Epidemiology is a population science that underpins health improvement and health care, and is concerned with the pattern, frequency, trends, and causes of disease this book teaches its applications to population health research, policy-making, health service planning, health promotion, and clinical care. The science concerned with the distribution and determinants of health and diseases, morbidity, injuries, disability, and mortality in populations disease does not occur randomly: epidemiology uses systematic approaches to study the differences in disease distributions in subgroups. Epidemiologic methods were primarily used in the studies of infectious diseases, such as tuberculo- sis, in uenza, typhoid, and diphtheria by the 1940s, most of the major infectious diseases had been.

Semmelweis’s work on childbed fever is not only an exemplar in epidemiology, it is also a classic case study in the philosophy of science, used by several philosophers to develop theories of explanation (hempel, 1966, lipton, 2004) semmelweis was faced with differing rates of childbed fever in two hospital wards, and he was sceptical of. Air pollution is now becoming an independent risk factor for cardiovascular morbidity and mortality numerous epidemiological, biomedical and clinical studies indicate that ambient particulate matter (pm) in air pollution is strongly associated with increased cardiovascular disease such as. It is an alternative to epi 200a and is designed for students majoring in epidemiology or biostatistics, or for students who desire a more detailed introduction into the main issues encountered in the design, implementation, and analysis of epidemiologic studies.

Abstract causation is an essential concept in epidemiology, yet there is no single, clearly articulated definition for the discipline from a systematic review of the literature, five categories can be delineated: production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic. Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems epidemiology is focused on. Analysis of categorical data in epidemiologic studies methodologies used in epidemiologic studies of diet and health in the context of us and international di- ies of cardiovascular diseases review of evidence of genetic, environmental, and behavioral causes of. In social epidemiology, to speak of theory is simultaneously to speak of society and biology fully embraces a social production of disease perspective while aiming to bring in a comparably rich biological and ecological analysis fewer than 25 epidemiological studies have explicitly investigated somatic consequences of racial.

Epidemiology has since moved beyond its origins in the study of infectious diseases, expanding to study the patterns of various health problems, including chronic diseases like cancer and heart disease, and their causes in human populations.

The major in epidemiology is designed for students pursuing careers in the study of patterns of diseases, disabling conditions, and other indicators of health in human populations. Public health sciences course descriptions ie chronic diseases, metabolic disorders, and cancer, will be examined major epidemiological studies, theories, and methods of assessment will be examined throughout the course this course provides a broad and comprehensive understanding of cardiovascular diseases (cvd). In cardiovascular epidemiology, adopting a life course approach presents major challenges for both the design and analysis of epidemiological studies 85 few researchers are fortunate enough to have access to a birth cohort study the maturation theory, and the biological basis of the human mind, 1920s-1950s in: benson kr, maienschein j.

Studies of the epidemiology of infectious diseases include evaluation of the factors leading to infection by an organism, factors affecting the transmis- sion of an organism, and those associated with clinically recognizable disease. Scientific theories provide explanations and predictions for epidemiologic studies of disease etiology and prevention causal theory is the key example for epidemiologic science, although theories of selection processes, theories of health, and theories of probability and statistics are also core the same cannot be said of most biological. Analysis of common multifactorial diseases such as cvd [cardiovascular disease] is hindered by the interdependence of genetic and environmental factors and the difficulties that are inherent in separating the influence of individual factors (lara-pezzi et al 2012, 434.

  • For each disease (cancer, ulcer, infectious disease, etc), epidemiological studies and biological research establish a system of causal factors involved in the production of the disease in this view, the unification of explanation is given by means of an organized collection of explanation schemas that characterize the causes of numerous.
  • Accumulating evidence of a link between diet and prevalent chronic disease has led to new investigations in nutritional epidemiology epich research supports a panoply of approaches, from detailed dietary analysis to prevention of disordered eating to investigation of obesity, physical activity and cancer etiology.

On the basis of accumulated scientific evidence from epidemiological studies and research on preventive medicine showing that cardiovascular diseases are associated with unhealthy lifestyles and human behaviours, the concept of community intervention was introduced to the field of cardiovascular disease prevention in the late 1960s and early. Classic epidemiologic theory cardiovascular diseases 16 etiology of a disease epidemiologic studies often identify cause-effect relationships before a biological mechanism is identified. Studies range from genetic and molecular studies of the mechanisms of cardiovascular disease to studies of vascular properties, lifestyle interventions, and responsiveness to preventive pharmacotherapy cardiovascular epidemiology training program cardiovascular epidemiology, vascular diseases, kidney diseases, genetic epidemiology.
