- Explain how loss to follow-up could bias findings in a cohort study of physical activity in college and subsequent diagnosis of diabetes.
- Explain how recall bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood (while age 18 to 24 years)
- Explain how selection bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood. Assume cases are identified as adult diabetic patients attending a diabetes management seminar at a local hospital and controls are selected from non-diabetic patients admitted to the hospital during the week the seminar was offered. Further assume that cases and controls are matched on age and sex.

In a study on the physical activity of people, researchers
measured overall physical activity as the total number of
registered movements (counts) over a period of time and then
computed the number of counts per minute (cpm) for each subject.
The study revealed that the overall physical activity of obese
people has a mean of μ=322cpm and a standard deviation σ=92cpm. In
a random sample of 100 obese people, consider x ̅, the sample mean
counts per minute.
Now suppose...

number of counts per minute (cpm) for each subject (International
Journal of Obesity, Jan. 2007). The study revealed that the overall

Infertility treatment and Asthma: The
millennium cohort study was set up as a nationally representative
study of 18818 infants born from 2000-2002 in the UK who are
followed up over time for different health outcomes. At the time of
enrolment mothers were asked about conception history which was
categorised into the following….
Unplanned (unplanned, unhappy about pregnancy)
Mistimed (unplanned, happy about pregnancy)
Planned (planned and time to conception<12 months)
Untreated-subfertile (planned and time to conception >12
months)
Ovulation induction (planned...
