Prevalence of Non-alcoholic Fatty Liver Disease among Patients with Diabetes Mellitus Attending Primary Health Care Centers in Bahrain
Objectives: We aimed to identify the prevalence of non-alcoholic fatty liver disease (NAFLD) among patients with type-2 diabetes mellitus (T2DM) and to assess the possible risk factors. Methods: In this retrospective cross-sectional study, a random sample from patients receiving treatment for T2DM in the non-communicable disease clinic, primary health centers, Bahrain in 2018 was reviewed. Three-hundred eighty-two patients who underwent abdominal ultrasonography were selected for the study. Detailed patients’ data were collected and statistically analyzed. Prevalence of NAFLD and its’ possible risk factors were assessed. Results: The study populations were mostly females (235 (61.5%) patients). The mean age was 5912 years. Hypertension was the most frequent associated disease (221 (57.9%) patients). Most of the patients were either overweight or obese, 103 (30.5%) and 197 (58.3%), respectively. Elevated alanine aminotransferase (ALT) was found in 75 (21%) of 357 (93.5%) tested patients. Two-hundred sixty (68.06%) patients had fatty liver based on ultrasound imaging. In univariate analysis, female gender (p=0.013), high body mass index (BMI) (p<0.0001), high waist circumference (p=0.011) and high triglyceride levels (p=0.043) were significant risk factors for fatty liver. In binary logistic regression, BMI was the independent risk factor for fatty liver (p=0.005). Conclusions: The prevalence of NAFLD among patients with T2DM was found to be high. However, it was comparable to what has been reported in other studies. Female gender, high BMI, waist circumference and triglyceride level are risk factors for NAFLD. BMI is the independent risk factor.
