Hi Magda,
You are right and I don't for one second believe that the researchers
involved in the study were doing anything but the best that they could.
Certainly it is clear in the paper that they were comparing a breastfeeding
support intervention to standard care and not an exclusively breastfed group
to a formula fed group. However, it is also clear that whomever wrote the
press release did not make this clear enough (and the authors did not have
input??) I think it's probably the news reports more than anything that
concern people. I just wish that they would look infant formula/other
milks/foods as the exposure rather than breastmilk, especially in relation
to asthma. I think that this study suffers from "misclassification bias" as
many others do! Breastfeeding is normal, it should be the control, not the
treatment.
