Pickett KE, Kelly S, Brunner E, et al. published an ecological study in the Journal of Epidemiology & Community Health in 2005 titled Wider income gaps, wider waistbands? An ecological study of obesity and income inequality. According to the methods section of the study aggregate data was collected from the populations of 21 countries worldwide on income inequality and three outcomes: the proportion of males and females who were obese, diabetes morality rate, and calorie intake. Then statistical methods were used to measure the associations between income inequality and each outcome. The following conclusion was stated in the abstract of the article “Obesity, diabetes mortality, and calorie consumption were associated with income inequality in developed countries.”

In your own words explain why this ecological study is an analytical study. Use evidence from the information provided above to support your reasoning. (4 pts)

Why is this study considered an ecological study design? (Hint: It is not related to whether the study is descriptive or analytic) (2 pts)
