Abstrakt:	Background: Physical activity (PA) regulates intrahepatic storage of fat and reduces the risk of liver steatosis. Given our limited understanding of the pathogenesis of metabolic complications in people with HIV (PWH), it remains unclear whether evidence from the general population can be extrapolated to PWH. We investigated the association between PA and liver steatosis in a single site of the Swiss HIV Cohort Study. Methods: We screened consecutive Swiss HIV Cohort Study participants using vibration-controlled transient elastography and defined liver steatosis as controlled attenuation parameter ≥248 dB/m. PA was measured using the International PA Questionnaire. We evaluated the association of 3 different measures of PA with liver steatosis in separate multivariable logistic regression models. Results: Of 466 participants, 127 (27.3%) were female, median age was 52 years (interquartile range 43-59), and 244 (52.4%) were overweight (body mass index [BMI] ≥25 kg/m 2 ). Liver steatosis was present in 235 (50.4%) individuals. In multivariable analysis, PA below the recommendations of the European Association for the Study of the Liver was associated with steatosis (adjusted odds ratio, 2.34; 95% confidence interval [CI]: 1.44 to 3.85). Using alternative scales of PA, including metabolic equivalents task minutes (min) per week (adjusted odds ratio 0.76, 95% CI: 0.60 to 0.94) and sitting hours per day (aOR, 1.16; 1.07 to 1.26), yielded comparable results, and associations were similar when we restricted the analyses to lean (BMI <25 kg/m 2 ) subjects. Conclusions: Insufficient PA and prolonged sitting time were associated with liver steatosis among PWH, independent of BMI. Our results support the importance of promoting PA to prevent liver steatosis in PWH. (Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.)
