Risk of development of diabetes according to FPG in the Singapore Impaired Glucose Tolerance Follow-up Study
| Glucose tolerance based on FPG criteria | n | Percentage who developed diabetes | Odds ratio (95% CI) |
|---|---|---|---|
| Analyses with subjects pooled within categories of FPG if FPG 5.6–6.9 mmol/l | |||
| FPG < 5.6 mmol/l | |||
| NGT* | 200 | 2.4 | 1 |
| IGT* | 89 | 19.1 | 9.7 (3.5–26.3) |
| FPG 5.6–6.0 mmol/l | 137 | 22.2 | 12.4 (4.7–32.8) |
| FPG 6.1–6.9 mmol/l | 43 | 55.2 | 55.1 (20.4–148.7) |
| Analyses with study subjects stratified by both FPG and 2-h PG criteria | |||
| FPG < 5.6 mmol/l | |||
| NGT* | 200 | 2.4 | 1 |
| IGT* | 89 | 19.1 | 9.7 (3.5–26.8) |
| FPG 5.6–6.0 mmol/l | |||
| NGT* | 66 | 9.6 | 4.4 (1.3–14.6) |
| IGT* | 71 | 31.1 | 19.8 (7.4–53.5) |
| FPG 6.1–6.9 mmol/l | |||
| NGT* | 10 | 28.6 | 17.6 (4.0–77) |
| IGT* | 33 | 59.8 | 66.2 (24.1–182.1) |
Odds ratios of future diabetes were estimated using logistic regression analysis and were adjusted for age, sex, and ethnic group. Data are presented for glucose tolerance determined by FPG with and without stratification by 2-h PG following a 75-g OGTT.
