Relation between Healthy Eating Index and Resting Metabolic Rate

Previouse studies demonstrated inverse association between healthy eating index and alot of chronic diseases like cardiovascular disease and cancer and mortality. Since there are limited study about relation between healthy eating index and reting metabolic rate. considering the results of some studies about the relation between weight, body composition and blood suger and considering the association between these factores and RMR,  the aim of this study is to investigate this association.

this study is a cross sectional study that was conducted on  256 subjects who were above 18 years old. Body composition, resting metabolic rate, were evaluated.  Dietary intakes including macronutrient and energy intake of participant were mentioned using a validated  food frequency questionnaire 168 items. resting metabolic rate was evaluated by inderect calorymetry(MetaLyzer 3B-R3) and body composition was assested by Multi-frequency bioelectrical impedance analyzer InBody 770 scanner (InBody co, Seoul, Korea).To evalute relation between healthy eating index with body composition and resting metabolic rate, ANCOVA was used. Also curve estimation was performed to find linear association between RMR and HEI.

this study did not found significant relation between healthy eating index and resting metabolic rate in both gender(men: p=0.83, women: p= 0.9). The score of healthy eating index in men was higher than women and with age increased, the score of healthy eating index increased.

Current study did not demostrate  any  significant differences between resting metabolic rate and body composition in tertiles of healthy eating index.
