BACKGROUND
Nonalcoholic fatty liver disease is one of the commonest liver disorders with a prevalence of 20-30% in western population. Cases range from asymptomatic to nonalcoholic steatohepatitis to cirrhosis of liver.
The aim of the study is to apply Indian diabetes risk score as a screening test for identification of hidden cases of nonalcoholic fatty liver.
MATERIALS AND METHODS
An observational study conducted in a tertiary care hospital among 412 adult cases subjected to ultrasound examination of abdomen for various reasons fulfilling inclusion criteria. Indian diabetes risk score is based on simple questionnaires like age, physical activity level, family history of diabetes mellitus and measurement of waist circumference and the score is classified as low risk <30, medium risk 40-50 and high risk >60. Nonalcoholic fatty liver disease was diagnosed on the basis of ultrasonographic criterion and statistical analysis done.
RESULTS
Out of 412 cases with a male-female ratio of 1.64:1, 37.5% had fatty liver, maximum incidence in the age group 21-60 years. The mean blood pressure systolic and diastolic were 132.6±14.6 and 82.7±9.0 mm of Hg and mean age, body weight, BMI and IDRS were 41.5±14.0 years, 59.4±11.4 Kg, 22.8±4.1 kg/m2 and 43.4±17.9, respectively. A score of 60 or more and 70 or more predicted fatty liver with a sensitivity and specificity of 73.5% vs. 73.2% and 95.2% vs. 68.6%.
CONCLUSION
The study concluded with the inference that a simple scoring system relating to Indian diabetes risk score when used judiciously can be used to diagnose high-risk individuals with nonalcoholic fatty liver disease.
