With respect to<br> the increased prevalence of obesity in Iran and the world, this study aimed to investigate the relationship between<br> fatty liver and obesity in 6 -18 year-old children.<br> Methods: In this case-control study, 25 overweight children and 24 obese children, who had inclusion criteria,<br> were selected by convenience sampling method. Then 27 children and teenagers with normal weight and the<br> same sex and age were selected as the control group. Weight and height of the sparticipants were measured and<br> recorded, liver enzymes ALT and AST were performed for them. Data was analyzed in SPSS software using<br> chi-square test, one-way ANOVA, Tukey range follow-up, and logistic regression. The significant level was set<br> at p<0.05.<br> Results: The results showed that the relative frequency of occurrence of fatty liver increased significantly<br> along with increasing body mass index (p<0.001). There was a significant relationship between sex, body mass<br> index, and the prevalence of fatty liver in the participants. However, no significant relationship was found between<br> fatty liver disease and AST and ALT (p>0.05).<br> Conclusion: There was a strong relationship between NAFLD and the abnormal body mass in children. It<br> will be very useful if obese children to screen for susceptible to NAFLD</p> Fatty Liver, Obesity, Children 16 20 http://ijca.iums.ac.ir/browse.php?a_code=A-10-1-43&slc_lang=fa&sid=1 Mahyar Mohammadifard mohammadifard@yahoo.com 1003194753284600310 1003194753284600310 No Birjand University of Medical Sciences, Birjand, Iran. mahyar Mahmoud Zardast dr.zardast@yahoo.com 1003194753284600311 1003194753284600311 Yes Birjand University of Medical Sciences, Birjand, Iran Vahideh Sabeti 1003194753284600312 1003194753284600312 No Birjand University of Medical Sciences, Birjand, Iran
