Introduction: The increased prevalence of overweight, obesity, and metabolic syndrome has revealed that liver enzymes have a potential role as determinants of metabolic conditions such as, hyperlipidemia, and Cardiovascular Disease (CVD). Aim: The study aimed to investigate the correlation between liver enzymes with anthropometric indices of obesity and lipid profile in different obese phenotypes at a tertiary care. Materials and Methods: The present observational study was conducted on a total of 180 obese participants of either gender in the age group 18-59 years from December 2018 to May 2019. These were further divided into two phenotypic groups viz., Metabolically Healthy Obese (MHO group; n=90) and Metabolically Unhealthy Obese (MUHO group; n=90) according to NCEP ATP III criteria.Traditional cardiovascular risk factors were evaluated in the study participants through anthropometric viz., Body Mass Index (BMI), Waist Circumference (WC), Hip Circumference (HC), waist–hip ratio (WHR), blood pressure and biochemical investigations i.e., serum glucose, lipid profile and liver enzymes. Data was analysed by using Microsoft excel software. Results: Among 180 obese participants, 76 were males and 104 females with mean age 40.42±10.84 years. In MUHO phenotype, Gamma Glutamyl Transferase (GGT) showed a strong positive correlation with BMI (r=0.413, p=0.00001), lipid parameters viz., LDL-C (r=0.3785, p=0.0001), TC (r=0.2953, p=0.0023), TG (r=0.2623, p=0.006) and negative correlation with HDL-C (-r=0.3167, p=0.001). No significant correlation was found in MHO phenotype between liver enzymes, BMI and lipid profile parameters. Conclusion: The results of this study indicated that GGT shows a strong positive correlation with traditional risk factors in MUHO participants. Thus, raised GGT may be considered as a risk marker of CVD in MUHO phenotype.
