Abstract

Physical activity is protective of premature mortality and those with liver disease are at an increased risk of early mortality. It is thus plausible to suggest that physical activity may have survival benefits among those with liver disease, but this has yet to be investigated. In a national sample, we examine the prospective association of objectively-measured physical activity on all-cause mortality among those with liver disease. Data from the 2003-2006 National Health and Nutrition Examination Survey (with follow-up through 2011) were evaluated (analyzed in 2015). Physical activity was assessed via accelerometry over 7days. Liver disease was assessed via self-report of physician diagnosis. Covariates included age, gender, race-ethnicity, serum cotinine, income-to-poverty ratio, C-reactive protein, cholesterol medication use, blood pressure medication use, alcohol behavior, self-reported liver disease status, serum alanine aminotransferase (ALT), serum gamma-glutamyltransferase (GGT) and comorbid illness. The sample included 162 adults who self-reported a physician-diagnosis of liver disease. The unweighted median follow-up period was 80.0months (IQR=68-91; SD=18.0). In the sample, 12,815 person-months occurred with a mortality incidence rate of 1.09 deaths per 1000 person-months. After adjustments, for every 10min/day increase in moderate-to-vigorous physical activity (MVPA), participants had an 89% reduced risk of all-cause mortality (HRadjusted=0.11; 95% CI: 0.02-0.47; P=0.004). There was no evidence of moderation by alcohol behavior, ALT, GGT or Hepatitis C virus status. These findings demonstrate that modest increases in MVPA may have survival benefits among those with a self-reported liver condition.
