TABLE 3.
Data Analyses When Gestational Weight Gain Is Measured at Intermittent Visits and at Delivery Only
| Model | Predictor | Hazard Ratio (95% CI) |
|---|---|---|
| Survival | Weight gain at multiple visitsa | 0.98 (0.97, 1.00) |
| Binomial | Weight gain between 30 and 36 weeks | 0.95 (0.89, 1.01) |
| Survival | Total gestational weight gainb | 0.99 (0.97, 1.01) |
| Binomial | Total gestational weight gainc | 0.89 (0.84, 0.93) |
a
Weight gain linearly interpolated between visits.
b
Weight gain linearly interpolated from baseline (weight gain = 0) to total weight gain at delivery.
c
Total gestational weight gain as measured at delivery.
95% CI indicates 95% confidence interval.
