**Spatio-Temporal Methods in Environmental Epidemiology**

Chapter 2 - Modelling Health Risks

** Summary **

This chapter contains the basic principles of epidemiological analysis
and how estimates of the risks associated with

exposures can be obtained.
From this chapter, the reader will have gained an understanding of the following
topics:

- Methods for expressing risk and their use with different
types of epidemiological study.
- Calculating risks based on calculations of the expected
number of health counts in an area, allowing for the

age-sex structure of the underlying population.
- The use of generalised linear models (GLMs) to model
counts of disease and case-control indicators.
- Modelling the effect of exposures on health and allowing
for the possible effects of covariates.
- Cumulative exposures to environmental hazards.
