Improvement in liver function after an intervention based on the Mediterranean diet in patients with non alcoholic fatty liver disease (NAFLD)

s / Clinical Nutrition ESPEN 13 (2016) e55ee74 e57 respectively. OSA severity was evaluated through the apnea-hypopnea index (AHI), and the disease was characterized as severe if AHI values were 30 episodes/hour of sleep. Results: The 86.7% of the patients were obese, while 92.3%, 100% and 98.5% had elevated WC, WHR and WHtR, respectively. A statistically significant positive correlation was observed between AHI and BMI, WC, WHR and WHtR (rho1⁄40.28, 0.49, 0.49 and 0.37, respectively, all P<0.05). Patients with severe OSA had significantly higher WC and WHR compared to those with mild or moderate disease (120.0±14.9 versus 111.5±12.4 cm, P1⁄40.05 and 0.99±0.09 versus 0.93±0.07, P1⁄40.02, respectively), while BMI and WHtR values did not differ between the two groups. Conclusions: Our findings confirm the involvement of obesity in OSA pathogenesis and suggest that WC and WHR may be better predictive markers for the disease severity compared to BMI.
