correlation between dietary inflammatory index (dii) and neck circumference (nc) in coronary artery disease patients

Background: inflammation, a risk factor for cardiovascular disease (cvd), is affected by diet.dietary inflammatory index (dii) is used to determine inflammation of diet. in addition, neck circumference (nc), an indicator for upper-body subcutaneous adipose tissue distribution, is related to cardiovascular risk factors. this study aimed to examine the correlation between dii and nc in a nationally representative sample case and control. methods: in this cross-sectional study, the case group was chronic heart disease patients hospitalized in al-zahra heart clinic, shiraz, iran (n=100). the control group did not suffer from any heart-related diseases. dietary intake data were determined using a single interview and food frequency questionnaire (ffq). nc was assessed using standard methods. nutritionist-4 software was used to analyze nutrient intakes from ffq. the method of shivappa et al. was used to calculate dii. results: the mean of nc in the case and control group were 39.09±4.18 and 36.68±4.32 cm. the mean of dii in the case and control groups were -0.018±1.53 and 0.40±155. there was no significant difference between the dii score of the case and control groups (p=0.056, t=-1.922). no significant correlation was observed between dii score and nc in the case (p=0.750,r=0.032) and control (p=0.294, r=0.106) groups. conclusion: there was no correlation between dii score as a risk factor for cvd and nc in both case and control groups.
