Leisure-time physical activity was associated with 42% lower odds of significant liver fibrosis (OR 0.58) in U.S. adults, regardless of obesity or diabetes status.
Does moderate-to-vigorous leisure-time physical activity reduce the likelihood of clinically significant liver fibrosis in U.S. adults?
Regular moderate-to-vigorous leisure-time physical activity is independently associated with a lower likelihood of clinically significant liver fibrosis, regardless of obesity or diabetes status.
Absolute Event Rate: 0% vs 0%
Background/Objectives: We investigated the association between leisure-time physical activity (LTPA) and liver fibrosis, and whether this relationship differs by obesity and diabetes status. Methods: We conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 2017–March 2020 cycle. LTPA was assessed using the Global Physical Activity Questionnaire (GPAQ) and classified as physically active if engaging in ≥600 metabolic equivalent (MET)-minutes per week of moderate-to-vigorous activity, or inactive. Clinically significant liver fibrosis was defined as liver stiffness measurement (LSM) ≥ 8.0 kPa on transient elastography. Multivariable logistic and linear regression models estimated adjusted odds ratios (ORs) for significant liver fibrosis, with additional subgroup analyses according to obesity and diabetes status. Results: In 7662 U.S. adults, physically active participants (n = 2721) had a lower prevalence of significant fibrosis than inactive individuals (5.4% vs. 11.4%, p < 0.001). In multivariable analysis, Participants who were physically active were associated with 42% lower odds of having fibrosis (OR 0.58, 95% confidence interval CI 0.41–0.82; p = 0.004). This association remained consistent in subgroup analyses stratified by obesity and diabetes status, even in the non-obese subgroup with body mass index (BMI) < 30 kg/m2 (OR 0.54, 95% CI 0.32–0.91; p = 0.022) and the non-diabetic subgroup (OR 0.59, 95% CI 0.39–0.90; p = 0.016). Conclusions: Regular moderate-to-vigorous LTPA was independently associated with lower likelihood of clinically significant liver fibrosis. This beneficial association was significant regardless of obesity or diabetes status, suggesting that LTPA may play a clinically meaningful role in populations at high risk for progressive liver disease.
