Textbook (Recommended): An Introduction to Epidemiology (7 th ed), by Ray M. Merrill GRADING: Quizzes/labs: 20% Mid-term exam: 30% Oral presentation: 20% Final Exam: 30% Grades A-F will be assigned as follows: = A = A = B = B = B = C = C = C = D = D 59.9 and Less = F 1

2 Quizzes and tests CANNOT be made up at a later time, unless a physicians statement is presented certifying illness at the time of the test. Failure to take a quiz, will automatically give a score of zero on that quiz. Failure to take the mid-term or final exam will jeopardize the student s chance of having the course approved. The University provides reasonable accommodations for students with documented physical or learning disabilities. Contact the Office of Disability Services for evaluation and guidance on such matters at (951) The office is located in La Sierra Hall, Suite 100. Students with such documented disabilities that require reasonable accommodations in order to participate in course activities or meet course requirements should contact the instructor during posted office hours or by appointment during the first two weeks of the quarter. COURSE LEARNING OUTCOMES Introduction to Epidemiology (HLSC 467) is a 3-unit course designed to provide a general introduction to the basic concepts and methods of epidemiology. After completing the course, students will be able to: 1. Explain the basic vocabulary, concepts and methods of epidemiology. 2. Discuss the development of epidemiology and the contribution of several historical examples of epidemiologic research to public health. 3. Describe the applications of epidemiology to the investigation of current public health problems and in clinical settings. 4. Calculate and interpret basic measures of disease occurrence in populations such as incidence, prevalence and other crude and specific measures of mortality and morbidity. 5. Calculate and interpret absolute and relative measures of effect including risk difference and relative risk. 6. Describe the basic methods for investigating and controlling an outbreak of a health problem in a community. 7. Describe the contribution of person, place, and time factors to the current understanding of disease causation. 8. Describe models of causation and the criteria for causal association. 9. Discuss the major types of study designs and their strengths and limitations. 10. Describe confounding and other common sources of bias and the methods used to control these biases. 11. Discuss the general principles and problems of mass screening for chronic diseases. 12. Define and calculate sensitivity, specificity, and predictive value positive and predictive value negative. 13. Critically read and interpret results of population research published in professional journals. 2
