Abstrakt: Objective: This study investigated copper (Cu) status in relation to abdominal obesity indices and liver function in patients with non-alcoholic fatty liver disease (NAFLD). This case-control study was carried out on 80 overweight/obese patients with NAFLD and 80 apparently healthy age, sex, and body mass index (BMI)-matched controls. A validated and reliable 168-item semi-quantitative food frequency questionnaire was completed for each subject and fasting serum levels of liver aminotransferases, ferritin, Cu and ceruloplasmin were assessed.
Results: Mean intakes of energy and carbophydrate were significantly lower in patients with NAFLD than the control group while mean protein intake was highre (p < 0.05). Although mean Cu intake was greater in cases than controls, low dietary intake of Cu was found in 7.5% and 32.5% of the cases and controls, respectively. Apart from serum levels of liver aminotransferases (p < 0.001) and ferritin (p = 0.010), no significant differences were found in serum levels of Cu and ceruloplasmin. Serum and dietary Cu were positively correlated with obesity indices and serum ceruloplasmin was correlated with waist to height ratio and ferritin only in cases (p < 0.05). Low Cu intake (< 0.95 mg/day) was more likely to increase the odds of NAFLD (p for trend = 0.002), after adjusting for potential confounders.
