GG102 Lecture 27: GG102 lesson 27
Document Summary
In the middle latitudes of the northern hemisphere, for example, we can frequently observe distinct differences in health and life expectancies that appear to be aligned along a west-east gradient. In short: people in the west end of cities can be shown to be richer and live longer than those in the east end. In hamilton, for example, a study related levels of income with geographical location and health. (the authors studied this relationship by examining more than 5,000 people who had been referred for lung function tests. Next, the researchers estimated the patients" household incomes by linking their postal codes to the 1996 census. Finally, to make sure that only income accounted for the observed differences in mortality, the researchers adjusted the mortality for such parameters as age, sex, and body mass index). The study showed a clear link between poverty and poor health.
