Background:Non-alcoholic fatty liver is the most chronic liver disease that eventually can become cirrhosis. One of the underlying assumptions for the fatty liver created by inflammation of the hepatocytes. We aimed to assess the association between non-alcoholic fatty liver disease (NAFLD) and sub-clinical inflammation.Materials and Methods:This is a cross-sectional study which was conducted on 55 patients over 30 years, with NAFLD. Fatty liver grade was assessed using liver ultrasound. Liver enzymes (alanine aminotransferase, aspartate aminotransferase), anthropometric characteristics and inflammatory marker C-reactive protein (CRP) were measured. Qualitative variables (sex and fatty liver grade) and quantitative variables such as were compared with independent t-test and Chi-square test. Relationship between fatty liver grade and inflammatory index was assessed with SPSS software (version 20; SPSS, Inc. Chicago, IL, USA).Results:Non-alcoholic fatty liver grades were associated with CRP level and this relationship remains in statistically significant level even after adjusting the effects of confounding variables such as age, sex and body mass index of participants (P = 0.016).Conclusion:In this cross-sectional study, presentation of NAFLD showed a significant correlation with sub-clinical systemic inflammation and CRP level.
BackgroundExcessive daytime sleepiness (EDS) is a common sleep abnormality among adolescents, and it’s associated with increased risk of morbidity and mortality. We aimed to explore the relationships between eating behaviors and EDS among female adolscents.MethodsIn this cross-sectional study 988 Iranian adolescent girls aged between 12-18 years old were recruited. Presence of EDS was determined by the Epworth Sleepiness Scale, and eating behaviors was assessed by a pre-validated questionnaire. To investigate the association between dietary behaviors and the prevalence of EDS, we applied logistic regression analysis in crude and adjusted models (adjustments for age, physical activity, menstruation and second hand smoke and general obesity).ResultsThe prevalence of esccesive daytime sleepiness was obtained 24.3. The participants who consumed a major meal three times daily had a 0.56 lower odds for EDS compared to those who consumed a single major meal (OR: 0.46, 95% CI: 0.21- 0.91). Individuals with a ‘high-rate of food chewing’ were less likely to have EDS (OR: 0.55, 95% CI: 0.29 -1.04) compared with low and moderate rate of food chewing. Compared with those who consumed fried or spicy foods daily, individuals who never consumed fried (OR: 1.8, 95% CI: 0.55- 5.86) or spicy foods (OR: 1.71, 95% CI: 0.55- 5.29) had a greater risk for EDS. In addition, there were direct associations between lower meal regularity (OR: 0.53, 95% CI: 0.29- 0.95) and intra-meal fluid intake (OR: 3.00, 95% CI: 1.2- 7.3) with EDS in adjusted models. Neither in the crude nor in the adjusted models, were there significant associations between breakfast intake and frequency of snack consumption with EDS.ConclusionThe lowest frequency of main meal frequency, irregular meal consumption, breakfast skipping, low rate of food chewing, intra-meal fluid intake, and consumption of spicy and fried foods were associated with increased odds of EDS. Further prospective studies are required to confirm this finding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
