Vitamin D concentration and other biomarkers, SUDs severity and other psychiatric disorders, cognitive functioning and impulsivity were collected at hospital admission (T0). Perceived negative affectivity and craving (for the main substance and food) were collected at T0 and hospital discharge (T1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>About 89.3% of the participants had a vitamin D deficiency as defined by French recommendations (&lt;\u200930\u2009ng\/mL). Using univariate between\u2010group analyses, vitamin D deficiency was associated with higher body weight and lower calcium plasma levels at T0, as well as increased craving intensity for both the substance at the origin of the treatment and food at T1. Multivariate regression analyses showed no significant associations between vitamin D or calcium levels and craving intensities at T1.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study confirms the high prevalence of vitamin D deficiency among inpatients treated for SUDs.
