The adjusted association of tooth fracture experience related to physical exercise by the complex-sample multivariable logistic regression models.
| Variables | Model 1 | Model 2 |
|---|---|---|
| Adjusted OR (95% CI) | Adjusted OR (95% CI) | |
| Sex (Ref. = female) | 0.98 (0.92–1.04) | |
| Grade | 1.02 (1.01–1.04) | |
| Days of >60-min physical exercise | 1.03 (1.02–1.05) | 1.01 (0.99–1.03) |
| Days of intensive physical exercise | 1.05 (1.03–1.07) | 1.03 (1.00–1.05) |
| Days of muscle strength exercise | 1.06 (1.04–1.07) | 1.04 (1.02–1.06) |
| Days of school gym class | 1.02 (1.00–1.05) | 0.99 (0.97–1.02) |
Dependent variable: tooth fracture experience (reference category = inexperience). Model 1: adjusted for sex and grade. Model 2: adjusted for sex, grade, days of >60-min physical exercise, days of intensive physical exercise, days of muscle strength exercise, and days of school gym class.
