    Abstract:
    BACKGROUND: The present study aimed to investigate the relationship between adiponectinaemia and food intake among obese women with nonalcoholic fatty liver disease (NAFLD). METHODS: In total, 60 obese women were examined by abdominal ultrasound for liver steatosis and subcutaneous and visceral adiposity. A standard interview (including questions about alcohol intake, medical history and physical activity), a physical examination (including height, weight, body mass index, waist and hip circumferences, waist-to-hip ratio, and body composition) and biochemical and clinical parameters (including serum glucose and insulin, homeostatic model assessment insulin resistance, lipid profile, aminotransferases, C-reactive protein, adiponectin, leptin, resistin, tumour necrosis factor-α, interleukin-6 levels and blood pressure) were performed. Food intake was evaluated by a qualitative food frequency questionnaire. RESULTS: Twenty-four NAFLD patients and thirty-six controls were analysed. The Mann-Whitney test showed lower adiponectin levels in the liver disease group compared to controls (P < 0.05). The Pearson correlation coefficient indicated that adiponectinaemia was negatively correlated with lipid profile and serum tumour necrosis factor-α (P = 0.05) and was positively associated with adiposity measures and serum leptin (P < 0.05). By simple linear regression, all of these variables predicted serum adiponectin levels. Chi-squared and Fisher's exact tests indicated that, in both groups, food intake showed no differences, although sucrose and fatty foods were associated with lower adiponectin levels in the liver disease group (P < 0.05 and P < 0.05, respectively), as well as in the control group (P = 0.05 and P < 0.05, respectively). CONCLUSIONS: Hypoadiponectinaemia in NAFLD was associated with dietary sucrose and fatty food intake, emphasising the important role of diet in the occurrence of this disease.
