| Risk factor | OR (95% CI) from multivariable model | Prevalence, % | Population attributable risk % (95% CI)* |
|---|---|---|---|
| Age 32-43 yr v. < 29 yr | 2.10 (1.51 to 2.91) | 36.4 | 24.5 (15.2 to 33.7) |
| Age 29-31 yr v. < 29 yr | 1.34 (0.94 to 1.90) | 28.6 | 7.0 (-1.1 to 15.0) |
| Family history of diabetes mellitus | 1.70 (1.29 to 2.23) | 42.1 | 21.6 (11.4 to 31.8) |
| Low diet quality | 1.62 (1.20 to 2.19) | 26.7 | 12.8 (5.2 to 20.4) |
| Body mass index > 23 v. ≤ 23 | 1.80 (1.37 to 2.37) | 51.5 | 28.1 (16.6 to 39.5) |
| Low diet quality and/or body mass index > 23 | 63.5 | 37.3 (25.9 to 48.7) | |
| All factors | 65.3 (55.6 to 75.1) |
Note: CI = confidence interval, OR = odds ratio.
*Continuous factors needed to be categorized: age was divided into tertiles, and body mass index was split into 3 categories (< 18.5, 18.5-23 and > 23); the highest category was selected as it was significantly different from the lower categories.
