Means (Least Square) of Dietary Inflammatory Index (DII) Scores by Diabetes Status and Severity of Diabetes
| Diabetes Status | LS Mean | Std Error | P-Value |
|---|---|---|---|
| No diabetes (n = 2634) | 0.508 | 0.05 | .03‡ |
| Pre-diabetes (n = 1176) | 0.50† | 0.06 | |
| Diabetes (n = 624) | 0.79*† | 0.10 | |
| Severity of Diabetes | |||
| Mild (HgbA1c 6.5% to 9%) (n = 375) | 0.55 | 0.11 | .0002§ |
| Severe (HgbA1c > 9%) (n = 94) | 1.37 | 0.14 |
The range of the DII scores was −3.41 to 9.05. Positive scores are pro-inflammatory and negative scores are anti-inflammatory.
↵* P < .05 for comparison of difference between non-diabetic and diabetic subjects.
↵† P < .05 for comparison of difference between pre-diabetic and diabetic subjects.
↵‡ P-value for comparison of mean difference in DII scores between non-diabetic, pre-diabetic, and diabetic subjects using regression analysis.
↵§ P-value for comparison of difference in DII scores between subjects with different level s of severity of diabetes using regression analysis.
