distress in maternal obesity: An administrative population health study

Reviewer's report:
I still don't believe that human placental lactogen gene expression should be mentioned in the first
paragraph of the discussion as it seems very speculative and tangential but I leave this point to the
discretion of the editor. However, I will remark that the relationship between GDM and PPD was recently
confirmed in a meta-analysis of over 2 million participants: Azami et al. 2019, Diabetes Research and
Clinical Practice, 149, 147-155. I believe that this should replace the research that has been added in the
fourth paragraph of the discussion.
