Observational Study Designs

A clinical pediatric nurse has noticed a rise in childhood cancer diagnoses among the Hispanic population served by the local clinic- The nurse is
concerned about this increase in cancer incidence in the patient population and turns to the literature to explore current research on this topic- The
nurse finds through the reading that there appears to be an association between parental smoking and childhood cancer and wonders if this could
be the cause of the rise in cases-
This type of suspected association between a risk factor (exposure) and a particular outcome (childhood cancer) can be evaluated using an
observational study design- This week, you were introduced to observational study designs used in epidemiology. For this Discussion, you will
identify an epidemiologic association of interest (e-g-, smoking and lung cancer, obesity and heart disease, hormone replacement/modification
therapy and breast cancer) and determine an appropriate observational study design for exploring that association-
To prepare:
-Review the different types of observational study designs presented in the Learning Resources: ecologic, cross-sectional, case-control, and cohort-
-Carefully examine the characteristics, strengths, and limitations of each design-
-Consider an association between a risk factor and a particular health outcome that is of interest to you- Then, select the observational study design
