I think that the information you have added is really good. However, I'm afraid that it isn't accessible to the general population yet. For the risk factors that you included, instead of using the effect sizes, you could list them in order of the effects with the first one listed having the highest relationship with PPD. Also for that, you may want to add citations to the end of the section and remove all the APA internal citations, they may make the page a bit confusing to people not used to APA format. I really like your discussion about the difference between correlation and causation. For the other section that you worked on, it may still be somewhat dense, and I'm not sure I see why that information is useful. I hope that this helps. Let me know if you have any questions.
