RESUMEN
OBJECTIVE: With hepatic steatosis (HS) being an established risk factor for CVD in the general population, it may also be a predictor of CVD in patients with schizophrenia. The aim of the present study was to investigate if time since schizophrenia diagnosis, body mass index (BMI), sex, metabolic syndrome, alcohol use, smoking, alanine transaminase (ALT), and body fat percentage (as measured by bioelectrical impedance) were associated with HS, determined by computed tomography (CT), in a population of patients diagnosed with schizophrenia. METHODS: Moderate to severe HS (40 CT Hounsfield units as threshold) was determined utilizing non-contrast enhanced CT. The association between the explanatory variables and outcome of HS was assessed using multivariable logistic regression. RESULTS: In the present study, 145 patients diagnosed with schizophrenia (mean age 42.2 years (SD ± 13.8)) were included, with 88 (60.7%) being male. On average, patients had been diagnosed for 14.8 (SD ± 10.7) years. A total of 31 (21.4%) patients had HS as determined by CT. The presence of HS was associated with ALT (OR 1.06, 95% CI (1.02-1.10) per 1 U/L increase), and the presence of metabolic syndrome (OR 62.89, 95% CI (2.03-1949.55)). The presence of HS was not associated with BMI, body fat percentage or time since diagnosis in the multivariable analysis. CONCLUSION: Higher ALT and the presence of metabolic syndrome were associated with HS in patients with schizophrenia utilizing multivariable analysis. The findings suggest that risk factors for HS are similar in both the general population and in patients with schizophrenia.
