Doesn't look like it amounted to much that is helpful. The 'core' according to the researchers was anxiety. We do not have the full study and without that we cannot comment. Although it looks like somebody did have access to thd entire study and labelled it 'highly biased'. Re depression there have been all kinds of associations observed. Some of the more outlandish have included lack of sunshine or lack of love or decision making. As someone observed here chicken/egg but that is generous in my opinion. Show me some properly done studies or at least some kind of info to back it up or F off.
