Correlation between Dietary Inflammatory Index (DII) and Neck Circumference (NC) in Coronary Artery Disease Patients

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.
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.
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.
There was no correlation between DII score as a risk factor for CVD and NC in both case and control groups.
