Objectives: Vitamin D deficiency is one of the implicated factors in ethio- pathogenesis of schizophrenia. Low serum vitamin D levels have been reported in many schizophrenia studies. However, the question is still not answered: Is there a correlation between disease activity and serum vitamin D levels? This is the first study evaluating the relationship between serum total vitamin D levels and disease activity, by comparing total vitamin D levels in two schizophrenia groups abruptly different in terms of disease activity.
