Cohort and Case Control Studies

In this short video, Dr Greg Martin discusses Case Control and Cohort studies. He compares the strengthes of each study design and descibes when each of them would be a preferred research method.

Global health (and public health) is truly multidisciplinary and leans on epidemiology, health economics, health policy, statistics, ethics, demography.... the list goes on and on. This YouTube channel is here to provide you with some teaching and information on these topics. I've also posted some videos on how to find work in the global health space and how to raise money or get a grant for your projects.

Please feel free to leave comments and questions - I'll respond to all of them (we'll, I'll try to at least). Feel free to make suggestions as to future content for the channel.

You really broke the differences between a case control and cohort study down very simplistically. Thank you!

[franklinchibuikeigbodekwe]

The explanation of the subject matter was spot-on. Thanks Dr. Greg!

[nastarannazari]

Thanks a lot, Sir. you made it so easy. It is so annoying that I have paid tuition fees for university and I still have to turn YouTube upside down to understand every concept better.

[Productivebear]

Concise and very helpful. I love the pictorial representation of the concepts!

[OursIslam]

Hi Greg -
In Kenneth J. Rothman's textbook; "Epidemiology: An Introduction (2nd edition)", Rothman talks about "Retrospective Cohort studies" (P.85). What is your take on that? He refers to a study conducted by Morrison et al. A study on data since 15th and 16th century in Florence.
It is quite confusing (not what I needed on top of the heap of other epidemiology confusion) :P

[garadqarash]

I have two questions to ask for those designs
1-When do we use case control study design?
2-when do we use cohort or longitudinal study design???

[jenniferevangeline]
