Abstract

Purpose: Given the high prevalence of non-alcoholic fatty liver disease (NAFLD) and the role of Alanine aminotransferase (ALT) in diagnosing liver injury along with the increasing prevalence of lifestyle risk factors, we aimed to evaluate the association between serum ALT level and lifestyle risk factors in a population-based survey. Methods: This was a population-based study conducted in rural and urban areas of Iran in 2016. Cluster sampling method was applied to enroll a total of 31,050 participants aged ≥ 18. Demographic data, anthropometric measures, and laboratory samples were gathered. Multivariate logistic regression analyses were performed using three different cut-off levels for elevated ALT to assess the relationship between elevated ALT and lifestyle risk factors. Results: The prevalence of elevated ALT was significantly higher in men with elevated body mass index (BMI), waist-to-hip ratio (WTH), hip circumference, and salt consumption, likewise, in women with higher BMI and WTH. In the multivariate logistic model adjusted for age and sex, high WTH (adjusted odds ratio: 1.73; 95% CI 1.52–1.96), BMI > 25 (1.51; 95% CI 1.29–1.76), hip circumference (1.26; 95% CI 1–1.58), and current smoking (0.67; 95% CI 0.56–0.8) were associated with elevated ALT levels using American cut-off (ALT > 33U/L for male and ALT > 25U/L for female). Only physical measurements (BMI, WTH) but not lifestyle risk factors were related to the increased ALT regardless of the selected cut-offs. Conclusion: As elevated ALT was associated with several lifestyle risk factors, stewardship programs should be established to modify lifestyle risk factors, such as abdominal obesity and physical inactivity. © 2022, The Author(s), under exclusive licence to Tehran University of Medical Sciences.
