Table 6. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) for the associations between Adequacy of Prenatal Care Utilization index categories and neonatal intensive care unit (NICU) admission and perinatal mortality among preterm and term singleton newborns.
| Preterm (GA week 23–36) | Term (GA week 37–43) | |
|---|---|---|
| NICU admission | AOR (95% CI) | AOR (95% CI) |
| Intensive | 1.00 (0.91–1.10) | 1.08 (1.01–1.15) |
| Adequate (reference) | 1.0 | 1.0 |
| Intermediate | 1.09 (0.91–1.29) | 1.14 (1.04–1.25) |
| Inadequate | 1.06 (0.93–1.20) | 1.14 (1.05–1.23) |
| Perinatal mortality | ||
| Intensive | 0.72 (0.63–0.84) | 0.76 (0.59–0.97) |
| Adequate (reference) | 1.0 | 1.0 |
| Intermediate | 0.67 (0.50–0.89) | 0.82 (0.57–1.19) |
| Inadequate | 0.98 (0.82–1.17) | 1.37 (1.05–1.79) |
GA: gestational age.
The models are adjusted for maternal age, parity, education, region of residence and delivery.
