Correlational Study of Nonalcoholic Fatty Liver Disease Diagnosed by Ultrasonography with Lipid Profile and Body Mass Index in Adult Nepalese Population

摘要

Objective: The purpose of this study was to categorize patients into different grades of nonalcoholic fatty liver disease (NAFLD) by ultrasonography and to compare the findings with their serurn lipid profile. Materials and Methods: Descriptive, cross-sectional study design was used. One hundred and nine patients without a history of alcohol consumption of age more than 16 years attending general health checkup were selected at Tribhuvan University Teaching Hospital, Maharajganj, Kathmandu, as per the exclusion and inclusion criteria. Ultrasound scanning of the patients was done and their liver size, as well as grading of fatty liver, was done. Data were collected in predesigned pro forma and were analyzed using Statistical Package for the Social Sciences (SPSS) 16.0, IBM (SPSS Inc., Chicago, IL). Results: In this study, the mean age of fatty liver in males was found to be 44.3 years and in females was found to be 51.9 years. 22.9 of patients with NAFLD had increased liver size. Significant association with increasing grades of fatty liver was found with increasing levels of cholesterol (P = 0.028), low-density lipoprotein (LDL) (P = 0.017), liver size (P = 0.001), and body mass index (BMI) (P = 0.045) in patients diagnosed with NAFLD. No significant association with increasing grades of fatty liver was found with increasing levels of triglyceride (P = 0.32) and high-density lipoprotein (P = 0.25). Conclusion: Ultrasound is a safe and first-line modality for the evaluation of fatty liver and its grading. Increasing grades of fatty liver had significant association with increasing levels of cholesterol LDL, increasing liver size, and BMI of patients.
