Obesity and obstetric complications

In theory, (that is, you are not provided with a dataset to work on), you are requested to investigate the association between obesity and obstetric complications in a hypothetical representative sample of delivering mothers. List at least one complication measured as a continuous variable and another as categorical. Discuss other-than-the-outcome variables you would need to collect for this study (tip: consider demographic and health behavioral variables). List the scale of each variable. Suggest three different graphs that can be used to report your findings. Describe the results of this investigation
