Epidemiology Matters Offers A New Approach To Understanding And Identifying The Causes Of Disease -- And With It, How To Prevent Disease And Improve Human Health. Utilizing Visual Explanations And Examples, This Text Provides An Accessible, Step-by-step Introduction To The Fundamentals Of Epidemiologic Study, From Design To Analysis. Across Fourteen Chapters, Epidemiology Matters Teaches The Individual Competencies That Underlie The Conduct Of An Epidemiologic Study: Identifying Populations; Measuring Exposures And Health Indicators; Taking A Sample; Estimating Associations Between Exposures And Health Indicators; Assessing Evidence For Causes Working Together; And Assessing Internal And External Validity Of Results. What Is A Population And What Is Population Health? -- What Is An Exposure, What Is A Disease, And How Do We Measure Them? -- What Is A Sample? -- Watching A Sample, Counting Cases -- Are Exposures Associated With Health Indicators? -- What Is A Cause? -- Is The Association Causal, Or Are There Alternative Explanations? -- How Do Non-causal Associations Arise? -- How Can We Mitigate Against Non-causal Associations In Design And Analysis? -- When Do Causes Work Together? -- Do The Results Matter Beyond The Study Sample? -- How Do We Identify Disease Early To Minimize Its Consequences? -- Conclusion : Epidemiology And What Matters Most.
