Mapping Differences In Rates

There are numerous examples of mapping in which the main purpose was to compare rates of disease between communities some of these were reviewed in Chapter 1 and all the atlases which have been published obviously fall into this category.6-11 Figure 7.3 shows the distribution of standardized mortality ratios for bronchitis, emphysema and asthma in Scotland between 1979 and 1983. It shows quite clearly that the highest mortality was found in the industrialized central belt of Scotland. The...

The Arbroath Multiple Disease Study

The remainder of this chapter uses the format of the template previously outlined for describing an investigation about a suspected point source of pollution. Previous surveys of patterns of environmentally sensitive respiratory disease in central Scotland had demonstrated a high mortality from lung cancer in residential areas of towns downwind of foundries.22-24 The town of Arbroath in eastern Scotland contained a central industrial area which housed a foundry. Complaints of dust and fumes in...

Malaria And Insulin Dependent Diabetes Mellitus An Ecological Study

There is scientific merit in studying the association between insulin dependent diabetes mellitus and malaria, since they are both associated with the human leukocyte antigen system. The human leukocyte antigen system is involved in controlling immunological responses, and the association between this system and insulin dependent diabetes mellitus has long been established.12 Malaria is the most important natural selective factor on human populations that has been discovered to date.13 In areas...
