Abstract

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) with onset in youth may be more consequential for adverse outcomes than that detected later in adulthood. Transaminitis in the general population is a marker of the prevalence of MASLD. There are no previous community-based studies in Indian youth assessing the prevalence of transaminitis. The purpose of this study was to find out the prevalence of transaminitis, MASLD and elevated Fibrosis-4 (FIB-4) index among young South Indian adults.

Methods: This was a cross-sectional study done over a period of 1 year from January 2022 among adults aged 18-30 years. Multistage sampling was used to recruit participants with body mass index (BMI) < 30 kg/m² and without moderate to heavy alcohol consumption from four different sociogeographic regions. Detailed history, physical examination and investigations including liver enzymes (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]), platelet count, and metabolic workup were carried out. FIB-4 index and Nonalcoholic fatty liver disease-liver fat score (NAFLD-LFS) were calculated. LFS ≥ -0.64 was used to rule in MASLD.

Results: A total of 2373 (1170 males) participants with a mean age of 24 ± 3.5 years were included. Transaminitis (AST or ALT≥35 IU/L) was seen in 25.9% of the cohort. MASLD by NAFLD-LFS was present in 27.4% of the population. FIB-4 index ≥1.3 was found in 54 (2.27%) participants. Neck circumference and Trivandrum Medical College adiposity index were associated with transaminitis, MASLD, and elevated FIB-4. Blood pressure, triglycerides, and low-density lipoprotein cholesterol were higher, and high-density lipoprotein cholesterol was lower among participants with transaminitis, but they were not different among those with elevated FIB-4 index. BMI and waist-hip ratio were not different among participants with and those without transaminitis or MASLD.

Conclusion: There is a high prevalence of transaminitis and MASLD in community-dwelling young adult Indians. We recommend screening all young adult Indians for MASLD and transaminitis.
