Background: Nonalcoholic fatty liver disease (NAFLD) is a common chronic disease that is rapidly increasing worldwide.Aim: The aim of this study was to investigate the risk factors associated with NAFLD in nondiabetics from South India.Participants and methods: We recruited 345 asymptomatic participants consecutively, and the study period was between January 2014 and December 2017. All participants underwent risk factor evaluation, fasting serum lipid profile, C-reactive protein (CRP), hemoglobin A1c, liver function test, and abdominal ultrasound.Results: Of 345 participants, men represented 213 (71%). The mean age of the participants was 58.4±11.1 years, with age range from 24–68 years. Prevalence of NAFLD was seen in 22%. On risk factor evaluation, 107 (31%) were hypertensive, 89 (25.7%) smoked, 52 (15%) were overweight, 110 (24.9%) were obese, and 113 (32.7%) had dyslipidemia. The mean CRP was 12.7±9.5 mg/l. High γ-glutamyl transferase levels, elevated CRP levels, obesity (45, 59.2%), high total cholesterol (49, 64.4%), low levels of high-density lipoprotein (28, 36.8%), high levels of low-density lipoprotein (27, 35.5%), and high triglycerides (31, 40.7%) were significantly associated with NALFD compared with non-NAFLD. After adjustment using multiple regression analysis, obesity (odds ratio: 3.5; 95% CI: 2.18–6.16), high total cholesterol [odds ratio: 4.9; 95% confidence interval (CI): 2.91–9.43], low high-density lipoprotein (odds ratio: 2.3; 95% CI: 1.20–4.47), high low-density lipoprotein (odds ratio: 2.9; 95% CI: 1.58–6.17), high triglycerides (odds ratio: 2.4; 95% CI: 1.33–4.60), and elevated CRP levels (odds ratio: 2.0; 95% CI: 1.21–3.39) were significantly associated with NAFLD.Conclusion: Our study established obesity, CRP positivity, and dyslipidemia as independently associated with NAFLD in South Indian patients.
