This book introduces major topics in this field, and where applicable, illustrated by tables and figures from Norwegian and Swedish studies. The first twelve chapters concern epidemiologic methods, including discussion of study designs and bias, together with an overview of vital statistics and a discussion on causality. The final eight chapters discuss changes in health more generally (or the epidemiologic transition), prevention, an introduction to genetic epidemiology, infectious disease, reporting observational studies, and assessing new information. The book is aimed at students in medical school, as well as public health and other health sciences students at the Bachelor and Master’s level.
