Document Summary
Objectives: define epidemiology, what are the key terms in the definition of epidemiology, understand changes in health problems during the last century, contrast the different types of prevention. According to gordis: the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to control health problems . Terminology: distribution: frequency of disease, how often it is happening, determinants: causes of disease, control: how to stop or control the disease. How does epidemiology differ from clinical practice (medicine): epidemiology focuses on the entire population rather than individual cases. Etiology is the cause of the disease. Epidemiology seeks to find etiology in order to reduce morbidity and mortality. The older we get, the more we are affected by chronic disease. Discovering burden of disease can help health care providers: this concerns the logistics of actually providing care.
