The relation of body mass index and smoking with liver function

Abstract EN

Objective: To assess the effect of BMI and smoking on liver function.

Materials and methods: Case- series study was conducted to assess the relation between liver function tests(aspartate amino transferace (AST), alnine amino transferace (ALT), Alkaline phosphatase, lactate dehydrogenase (LDH), protein albumin and billirubin), and BMI and smoking in 1020 apparently healthy persons using commercially available kit.

Results: Significant direct relationship between liver enzymes activities, serum total protein and globulin and BMI were observed.

Albumin, bilirubin and A/G ratio values were decreased by increasing BMI.

Significant relation was observed between the mean activity of (AST) and cigarette smoking.

Significant inverse relationship was observed between mean values of total protein, albumin, globulin and bilirubin with cigarette smoking Conclusion: serum enzymes activities of (AST, ALT, ALP and LDH), total protein and globulin had direct positive relationship with BMI, while albumin, A/G ratio and total bilirubin had inverse relationship.

Smoking has a significant effect of on AST, total protein, albumin, globulin and total bilirubin, while doesn't affect ALT, ALP, and LDH.
