Excelsior College Annual Incidence of Gun Related Injuries During 2000 Questions

Before beginning this activity, review the Module Notes and readings on study designs (you may want to review the designs in the previous module as well).

You have now learned about the major study designs used in epidemiologic research, including experimental and observational approaches. As you complete this assignment, focus on the study objective, whether population is selected on the basis of exposure or outcome, if the exposure is assigned or occurs naturally, and the duration of the study. These are your clues to identifying the appropriate design!

In a MS Word or similar document, with each question numbered, respond to each of the questions below.

Choose the study design that is most appropriate for each question, choosing from the following options below. Provide your rationale for selecting the particular study design.

Case-control study

Experimental study

Prospective cohort study

Retrospective cohort study

Ecologic study

Cross-sectional study

1. A study that compared statewide average sales of ammunition and annual incidence of gun-related injuries during 2000.

2. To examine the association between indoor mold exposure and asthma among children, a random sample of households in Detroit, Michigan is recruited to participate in a study in 2011. Parents are interviewed about the child’s current lower respiratory symptoms, and air samples are taken inside the home on the same day as the interview to measure mold concentration.

3. To examine whether insurance coverage is associated with discharge to a specialized post-acute care facility (e.g., rehabilitation, skilled nursing, etc.) after a trauma hospitalization, 1241 trauma patients from the National Trauma Databank from 2002 to 2006 were assessed. The likelihood of discharge to a specialized facility was compared between trauma patients with Medicaid versus other insurance coverage.

4. To examine the association between phthalate exposure and birth defects of the male reproductive tract, 10,000 women who worked as cosmetologists are identified from NYS licensure records in 2005. Malformations are identified from the Georgia Birth Defects registry and are reported on a monthly basis. The women are followed for 5 years, with bi-annual phone calls to determine pregnancy status.

5. A study that concluded that a non-stimulant medication randomly allocated to children with ADHD was associated with improved cognitive and emotional function compared to children with ADHD treated with Ritalin or to children with ADHD who were not assigned to prescription treatments.

6. A study examines the prevalence of childhood trauma in patients with severe mental disorders.

7. A study examines the association between family history of cancer and risk of laryngeal cancer. Laryngeal cancers were identified from a registry between 1992 and 2009 and histologically confirmed. Cancer patients were contacted and asked about laryngeal cancer history in any first-degree relative along with other risk factors.

8. A study that found that adult residents of a small town in California who ate fish from a local PCB-contaminated river had a 1.5 times higher incidence rate of liver cancer incidence compared to residents in the same town who did not consume fish from the source, from childhood until after 20 years of follow-up.

9. A study that compared per capita sales of smokeless tobacco products and annual incidence of oral cancer in Minnesota counties during 2014.

10. A study that compares the prevalence of asthma among currently licensed cosmetologists with the prevalence of asthma among currently licensed realtors.
