Abstract |
Objectives |
The main objective of the study was to assess 25-hydroxyvitamin D (25(OH)D) status in a psychiatric population in France according to psychiatric diagnoses. The secondary objective was to investigate a correlation between 25(OH)D and CRP.
Methods |
A retrospective study from February 1st, 2014 to January 31, 2016, was carried out in a French psychiatric hospital. Inpatients with a 25(OH)D measure were included. Variables including ethnic origin, BMI, psychiatric diagnoses, medical history and CRP were collected. Factors associated with 25(OH)D and CRP were studied in univariate and multivariate analyses, as was the correlation between 25(OH)D and CRP.
Results |
Among 604 patients included, 80.6% presented 25(OH)D deficiency of which 46.9% with 25(OH)D<50nmol/L. 25(OH)D varied with age, ethnic origin, BMI, season, CRP and medical history. It was associated with schizophrenia in univariate analysis but not in multivariate analyses considering age and BMI. CRP varied with age, BMI and medical conditions but not with psychiatric diagnoses. 25(OH)D was inversely correlated with CRP.
Conclusion |
This psychiatric population was significantly more deficient in 25(OH)D than the French population in general. 25(OH)D was inversely correlated with CRP as observed in the general population.
