Part 1

The aims of a study, the kinds of variables being collected, and the study design are all closely interconnected. This is important to keep in mind when choosing a study design for your final project. For your initial post you will focus on at least two of the studies from your literature review. Each study should use a different study design. Summarize the study design used. Consider the stated objectives of the study and discuss why, based on the objectives, the researchers may have chosen to use the design they did. Which of these designs most closely relates to what you are planning on using in your final project and why?

Part 2

In your response to your classmate critique the chosen study design. Is this the best option for the proposed research proposal? Why or why not?

classmates Jacob’s response:

For Labarere’s study they utilized a random, open trial of 226 mother infant pairs who were initially breastfeeding.1 The pairs were divided into 2 groups, a control and an intervention. Interventions included verbal encouragement from the maternity ward staff, they were also given the number to a peer breastfeeding counselor, 10 weeks of paid maternity leave and 6 mandatory outpatient visits with their healthcare provider. Both groups were followed during their breastfeeding journey to see how long they breastfed for and to see how they felt their breastfeeding efforts were going. The control group who did not receive the extra support reported more breastfeeding difficulties and were less likely to be breastfeeding at 26 weeks postpartum. Laberere might have chosen this model to clearly show the importance of adequate follow up support with a breastfeeding mother when compared to a control group who received the typical amount of breastfeeding support that many mothers in our country receive.

Chung used over 500 studies to compile data about the benefits of breastfeeding, both short term and long term for the mother and infant.2 Studies included meta-analysis, primary studies and systematic reviews. Data from these studies indicated that infants who were breastfed had fewer respiratory tract infections and lower rates of type 1 & 2 diabetes, obesity and leukemia. Women who breastfeed also had lower rates of type 1 & 2 diabetes, as well as ovarian and breast cancer. Chung might have favored this design because there is so much research on the benefits of breastfeeding that he didn’t feel he needed to do a primary study, but rather use the vast research that has already been done to compile a review of many studies into one document.

In my final project I think I will go with a study design more like Labarere’s because there is more research already done on the benefits of breastfeeding and less on how to adequately support women who have made the choice to breastfeed or who prenatally are unsure of how they will feed their infant. Splitting the group into a control and an intervention group is a simple way to show the impact that the intervention has made, but I might propose a third group who receive a different type of support.
