Analysis of Suicidal Behavior and Chronicity of Depressive Symptoms in the Presence of Hypovitaminosis D

One of the risk factors for suicide includes the presence of depressive disorder and symptoms, which may be related to the reduction of 25-hydroxyvitamin D serum levels. In this scenario, evidence shows vitamin D deficiency as an important aspect, directly related to depressive disorder chronicity. To assess the association between Vitamin D serum levels and the intensity of depressive symptoms and suicidal behavior in a clinical sample of depressed patients. A cross-sectional study with 146 patients aged between 18 and 59, seen in two psychiatry ambulatories. Data collection involved measurement of serum 25-hydroxyvitamin D levels and assessment of the intensity of depressive symptoms and suicide risk. In the sample, 35% presented low Vitamin D serum levels and, in these individuals, the incidence of family history of Depressive Disorder (95.2%) and chronicity of severe depressive symptoms (47.8%) was higher. As to suicidal behavior, both groups presented high active suicide risk, with higher rates in the group with hypovitaminosis D. Only suicidal ideation was linked to lower Vitamin D levels (67.4% p= 0,005). In this study, hypovitaminosis D was associated with negative mental health outcomes, such as more severe chronicity of depressive symptoms and suicidal behavior, characterized by active suicidal ideation.
