AB - Objectives: Traumatic brain injury (TBI) is a major cause of long-term disability with variable recovery. Preclinicalstudies suggest that vitamin D status influences recovery after TBI. However, there is no publishedclinical data on links between vitamin D status and TBI outcomes. To determine the: (i) prevalence ofvitamin D deficiency/insufficiency, and associations of vitamin D status with (ii) demographic factors andTBI severity, and with (iii) cognitive function, symptoms and quality of life, in adults after TBI.Design: Retrospective audit of patients seen between July 2009 and March 2015. Serum vitamin D (25-hydroxy-cholecalciferol) was categorised as deficient (<40nmol/L), insufficient (40-70nmol/L) or replete(>70nmol/L).Patients: 353 adults seen in tertiary hospital clinic (75.4% lighter-skinned, 74.8% male, age median 35.1y,range 26.6-48.3y), 0.3-56.5 months after TBI (74.5% moderate-severe).Measurements: Serum vitamin D concentrations; Addenbrooke’s Cognitive Examination (ACE-R), BeckDepression Inventory II (BDI-II), SF-36 Quality of Life, Pittsburgh Sleep Quality Index.Results: 46.5% of patients after TBI had vitamin D deficiency and 80.2% insufficiency/deficiency. Patientswith vitamin D deficiency had lower ACE-R scores than those vitamin D replete (mean effect size ± SEM 4.5± 2.1, P=0.034), and higher BDI-II scores than those vitamin D insufficient (4.5 ± 1.6, P=0.003), correcting forage, gender, time since TBI, TBI severity. There was no association between vitamin D status and markers ofTBI severity, sleep or quality of life.Conclusion: Vitamin D deficiency is common in patients after TBI and associated with impaired cognitivefunction and more severe depressive symptoms.
