#12so you’d expect to see fewer cases the further south go. I wonder how that holds up?
You would need to be careful about comparing areas that are otherwise similar or do something more sophisticated than merely comparing rates of psychiatric hospitalization between two areas. Average incomes and other factors are probably important too.

What's left is to test this hypothesis.

#14What about other deficiencies? Other vitamins and nutrients? You'd expect people that are admitted to psychiatric hospitals to have more than one deficiency since they might not be able to take good care of themselves.

#15If you are going to supplement your vitamin D, just make sure to monitor your calcium too. My wife sees patients taking high doses of vitamin D, because their doctor puts them on it, or they do it themselves, and they do not realize that they are doing massive damage to their bodies because their low vitamin D levels are caused by a parathyroid tumor.

#16This is close to the rate of vitamin D deficiency in the general population, e.g. https://www.ncbi.nlm.nih.gov/pubmed/21310306
The study you linked was based on a threshold of 50 nmol/L, while the originally posted study used two thresholds, 30 nmol/L and 50 nmol/L. At the 50 nmol/L cutoff, the study you linked indicates a deficiency rate of 41.6% for the general population, compared to a rate of 91.3% among psychiatric patients according to the posted study.
I’d still take the posted study with a grain of salt. Vitamin D deficiency between individuals is likely to be highly correlated within a particular region and time period due to its dependence on weather, and the authors didn’t control for that. But they did say that this was just a pilot, and given the effect size it’s probably worth investigating further.
Edit: fixed units

You haven't tested

#18No comparison to prevalence of vitamin D deficiency in the general population?
They might not have the correct data for comparison -- you'd need to control for climate, so national or international rate of deficiency wouldn't be a good comparison.

Regarding the weather: most people most often stay indoors or in cars(does the glass filter the Vitmain-D causing rays), and usually wear long pants and a shirt, so only a small body area is exposed to the sun, so it's possible that even in summer, people suffer from Vitamin-D deficiency.

#20Most of these patients are likely exhibiting some spectrum of antisocial behavior, which means staying indoors or generally away from other people.
I don't think it's as interesting as it seems. I'm rather certain there's a sensible explanation.
