Association of dietary inflammatory index (DII) with Hypertriglyceridemic Waist Circumference Phenotype among Overweight and Obese Women: A cross sectional study
Abstract Aims: Recent studies have shown that increased dietary inflammatory index (DII) score or consumption of pro-inflammatory foods can lead to increased waist circumference (WC) as well as triglyceride (TG) concentrations in obese people. The purpose of this study is to examine the association between DII and hypertriglyceridemic waist circumference phenotype (HTGWCP) in overweight and obese women. Methods: This study was performed on 226 obese women aged from 18 to 48 years. We evaluated DII score by semi-quantitative food frequency questionnaire (FFQ) of 147 items. Biochemical parameters were measured and anthropometric assessments were performed. Results: There was a positive significant correlation between DII and HTGWCPs. In other words, with an increase in DII score, the odds of having abnormal phenotypes including; enlarged waist normal TG (EWNT) (OR=2.85, 95% CI=1.02 to 7.98, P for trend=0.04) , normal waist enlarged TG (NWET) (OR=5.85, 95% CI=1.1 to 31.11, P for trend=0.03), enlarged waist enlarged TG (EWET) (OR=3.13, 95% CI=0.95 to 10.27, P for trend=0.05) increase compared to normal waist normal TG (NWNT) phenotype.Conclusion: Increasing DII scores can increase abnormal phenotypes so may increase WC and TG levels in overweight and obese women.
