Vitamin D Deficiency Common in Schizophrenia

That is the title of this article  I am writing about. "A new study finds that vitamin D-deficient individuals are twice as likely to be diagnosed with schizophrenia as people who have sufficient levels of the vitamin. Vitamin D, produced by the skin after exposure to sunlight, helps the body absorb calcium and is needed for bone and muscle health. More than one billion people worldwide are estimated to have deficient levels of vitamin D due to limited sunshine exposure. Vitamin D is often linked to seasonal affective disorder (SAD), a type of depression that occurs the same time every year and maybe attributable to a lack of sunshine. Schizophrenia is a mental illness with symptoms that include delusions and hallucinations." I believe we do not get enough of sun because the type of medication we are on. I know when I was on Moban I could not be out in the sun because it effected my body because of the medication.
Although they do not discuss that here: ‘"Since schizophrenia is more prevalent high latitudes and cold climates, researchers have theorized vitamin D may be connected to the disorder. This is first comprehensive meta-analysis to study the relationship between the two conditions,’ said one of the study’s authors Ahmed Esmaillzadeh, Ph.D. ‘When we examined the finding of several observational studies on vitamin D and schizophrenia, we found people with schizophrenia have lower vitamin D levels than healthy people. Vitamin D deficiency is quite common among people with schizophrenia.’ The researchers reviewed the findings of 19 observational studies that assessed the link between vitamin D and schizophrenia. The meta-analysis found that people with schizophrenia had significantly lower levels of vitamin D in the blood compared to control groups." Does that mean there is not that much schizophrenia in Florida because it is warmer? I think it is all over the world.
The article goes on to say: ‘"The average difference in vitamin D levels between schizophrenic patients and control participants was -5.91 ng/ml. People with vitamin D deficiency were 2.16 times more likely to have schizophrenia than those with sufficient vitamin D in their bloodstreams. In addition, 65 percent of the participants who had schizophrenia also were vitamin D deficient. There is a growing trend in the nutrition science field to consider vitamin D and its relationship to conditions such as diabetes, cancer, heart disease, and depression,’ Esmaillzadeh said. ‘Our finding support the theory that vitamin D may have a significant impact on psychiatric health. More research is needed to determine how the growing problem of vitamin D deficiency may be affecting our overall health." It can cause problems in ordinary people so it can also affect those with schizophrenia. A person just wonders how much it does.
