3. Results
The mean±SD age of the participants was 34.44±7.27, 34.59±6.8 and
36.47±7.4 years in the 1st, 2nd, and
3rd tertile, respectively. The demographic
characteristics of the subjects are presented in Table 1.
The distribution of the DIP score between tertiles is shown in Table 2.
Large differences in DIP scores were observed for fat (P-value:0.04),
riboflavin (P-value<0.001), folic acid
(P-value<0.001), cobalamin (P-value=0.005), ascorbic acid
(P-value<0.001), vitamin A (P-value<0.001), beta
carotene (P-value<0.001), zinc (P-value<0.001), tea
(P-value=0.002), magnesium (P-value<0.001), onion
(P-value<0.001), fiber (P-value<0.001), caffeine
(P-value=0.03), SAFA (P-value=0.02), and cholesterol
(P-value<0.01) between the tertiles.
The mean±SD plasma levels of endothelial markers in different tertiles
are shown in Table 3. There was no significant association between DIP
and E-selectin in the crude model (P-value= 0.35) compared to model I
(P-value= 0.57), model II (P-value= 0.57) and model III (P-value= 0.67)
after adjusting for potential confounders (Figure 1).
The results showed no significant association between DIP and the plasma
level of sICAM-1 in the crude model (P-value: 0.83) compared to model I
(P-value: 0.98), model II (P-value: 0.98) and model III (P-value: 0.92)
after adjusting for potential confounders (Figure 2).
In addition, no significant association was found between DIP and the
plasma level of sVCAM-1 in the crude model compared to model I (P-value:
0.49), model II (P-value: 0.45) and model III (P-value: 0.50) after
adjusting for potential confounders (Figure 3).
