Abstract

Introduction: Vitamin D deficiency is a global problem that can negatively impact physical and cognitive function, with levels of 25(OH)D <20 ng/ml considered low. Anesthesiology and Intensive Therapy residents are particularly at risk of vitamin D deficiency due to limited sunlight exposure in their work environment, which can lead to decreased physical and cognitive function. A screening method is needed to detect early decline in physical and cognitive performance in these populations, and the Vitamin D Status Predictor (VDSP) questionnaire and Bioelectrical Impedance Analysis (BIA) for skeletal muscle body composition could be used as predictors compared to the gold standard of vitamin D levels. Aim and Objective: This study aimed to assess whether the VDSP questionnaire, body composition, and vitamin D levels could predict physical and cognitive function in Anesthesiology and Intensive Therapy residents. Materials and Methods: The study included 80 active Anesthesiology and Intensive Therapy residents at Dr. Soetomo Hospital who met the inclusion criteria and approved the research procedure. Each participant completed the VDSP questionnaire, underwent skeletal muscle weight measurement, had their blood levels of vitamin D examined, and completed physical function assessments using a hand grip dynamometer and cognitive function assessments using the Mini Mental State Examination (MMSE). Results and Conclusion: Two out of 80 subjects had vitamin D insufficiency (<30 ng/ml). The VDSP score was significantly related to Hand Grip Strengthening (HGS) physical function (r -0.243, P<0.05) but not to MMSE (P>0.05). Skeletal muscle scores were significantly related to HGS (r 0.428, P<0.05) but not to MMSE (P>0.05). Vitamin D levels were significantly associated with HGS (r 0.407, P<0.05) but not with MMSE (P>0.05). Of the three factors significantly related to HGS, namely skeletal muscle (ß 0.653, P<0.05) and vitamin D levels (ß 0.107, P<0.05), only skeletal muscle was a predictor of physical function assessment compared to cognitive function assessment. Skeletal muscle assessment and vitamin D levels can be used as predictors of physical function assessment compared to cognitive function assessment in Anesthesiology and Intensive Therapy residents.
