Multivariable logistic regression of risk factors for measles seronegativity.
| Variables (seronegativity <200 mIU/mL) | Reference | AOR (95% CI) | P-value |
|---|---|---|---|
| Interval since vaccination (per year increase) | Continuous | 1.11 (1.07-1.15) | < 0.001 |
| MCV Doses | 2 doses | – | – |
| 0 dose | 24.73 (16.26-37.61) | < 0.001 | |
| 1 dose | 2.39 (0.95-6.00) | 0.063 | |
| ≥3 doses | 0.95 (0.61-1.48) | 0.826 | |
| Region | Jiangsu | 1.73 (1.10-2.71) | 0.017 |
| Ethnic Group | Han | – | – |
| Uyghur | 0.54 (0.32-0.89) | 0.015 | |
| Kazakh | 0.88 (0.57-1.37) | 0.578 | |
| Migration Status | Permanent | 0.73 (0.38-1.38) | 0.330 |
Model adjusted for geographic region (Jiangsu vs. Xinjiang), ethnicity (Han, Uygur, Kazakh, Others), number of MCV doses (0/1/2/), time elapsed since last vaccination (years), age (years), and sex. Dependent variable: Measles seronegativity (IgG <200 mIU/mL).
