There is an urgent need for clinical randomized studies on this intervention, given that the literature now suggests that cardiovascular and digestive health could be improved using this relatively easy lifestyle change.
This is certainly consistent with my experience when teaching at a naturopathic medical school in the US. All physicians should have a solid background in accessing, assessing, and understanding peer-reviewed research. Although some in the ND field see evidence-based medicine as antithetical to their approach, this is starting to change.
The study states that women who experienced prenatal anxiety and sleep disorders during pregnancy were at a higher risk of suffering from prenatal depression, but it does not assess the directionality. Perhaps being depressed interferes with sleep and makes a pregnant mom more likely to feel anxious.
There are two scales mentioned in this paper: one is the Altered States of Consciousness Rating Scale (OAV) and the Mystical Experience Questionnaire. A psychometric evaluation of the OAV can be found in an open access article by Studerus et al, and the Mystical Experience Questionnaire is available here: https://www.ocf.berkeley.edu/~jfkihlstrom/ConsciousnessWeb/Psychedelics/Pahnke-Richards_Mystical_Experiences_Questionnaire.pdf
I would find it more helpful if the tables clearly reported type of injury or length of hospital stay; surgical vs "conservative" treatment is less meaningful. For example, a child might break a finger and receive surgery, but might have a closed head injury and not be treated through surgery, at least not immediately. Fear of permanent effects from spine or brain injuries is likely what worries parents most, and by extension, their health care providers.
This is an excellent example of how functional foods-as-medicine studies should be designed, executed, and reported. I was pleased that this was published as open-access, and that the study design was rigorous and transparent.

This association in humans has been studied extensively in population-based studies, including systeamtic reviews such as https://pubmed.ncbi.nlm.nih.gov/28534456/
