Vitamin d status and cardiometabolic risk factors in long-term psychiatric inpatients.

Objective: Low vitamin D levels are common in psychiatric patients, but a need for vitamin D supplementation in these individuals remains controversial. Low vitamin D levels are reportedly associated with high prevalence of cardiometabolic risk factors, and both are common in psychiatric patients, but the relationship between diagnosis and severity of illness and cardiometabolic risk status and the effect of vitamin D treatment on them is not known. We studied these relationships and effect of vitamin D(3) treatment on them in 290 long-term psychiatric inpatients.
