Prevalence, Metabolic Profile, and Associated Risk Factors of Non-alcoholic Fatty Liver Disease in an Adult Population of India.

Introduction Non-alcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease worldwide. NAFLD refers to a group of diseases that includes simple steatosis, nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. Unfortunately, there aren't many studies on NAFLD conducted in India. The majority of research involved specific populations, such as diabetics, pregnant women with gestational diabetes, and obese or non-obese people. When the current study was being planned, there were few population-based studies available. In almost all of the research, ultrasound was employed to identify NAFLD, and the whole spectrum of NAFLD was not assessed. The full spectrum of NAFLD in India must have been considered, including all stages of steatosis as well as hepatic damage as shown by high alanine aminotransferase levels and fibrosis. The purpose of this study was to determine the prevalence, spectrum, and metabolic determinants of NAFLD as assessed by FibroScan® (FibroScan® expert 630 machine; Echosens, Paris, France) in adults of Central India. Methods This cross-sectional study was conducted among 236 adults aged 18 years and above in three localities of Bhopal, India from March 2022 to October 2022. The study included males and females who provided informed consent and fulfilled inclusion criteria. One research assistant and one staff nurse solicited people to participate in the FibroScan® test during the community screening and shared information about the programme. All participants were subjected to the FibroScan® test. Results A total of 322 healthy adults were approached for possible inclusion in the study. Data from 236 subjects were available for analysis after meeting the inclusion and exclusion criteria. According to this study, 43.6% of the study population had NAFLD as detected by FibroScan®. Out of the total, 12.7% of subjects had steatosis grade 1 (S1), 12.3% of subjects had steatosis grade 2 (S2), and 18.6% of subjects had steatosis grade 3 (S3). High body weight, high waist circumference, high waist-to-hip ratio, high fasting sugar, high serum glutamate pyruvate transaminase (SGPT), high triglyceride levels and high very low-density lipoprotein (VLDL) levels were significantly associated with NAFLD. Conclusion In conclusion, 43.6% of the adult population of Bhopal, India is suffering from NAFLD. NAFLD is a severe burden in the Indian community despite being historically associated with the western world. Obesity, diabetes and dyslipidemia are significantly associated with NAFLD.
