Homework Answers
1.Smokers have a greater risk of developing type 2diabetes than do nonsmokers. The risk of developing diabetes increases with the number of cigarettes smoked per day.
The fact is true but there's bias. The study was conducted on a small group and also including hospital staff.
4. The magnitude is here underestimated. Smoking may make your body more resistant to insulin, which can lead to higher blood sugar levels. Uncontrolled blood sugar can lead to serious complications from diabetes, including problems with your kidneys, heart, and blood vessels.

Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain. The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...
