|---|---|---|
| 18.5 to 24.9 | 36 per 1,000 (so this does not happen in about 964 pregnancies per 1,000) | 17 per 1,000 (so this does not happen in about 983 pregnancies per 1,000) |
| 25 to 29.9 | No difference compared with women with a BMI 18.5 to 24.9 kg/m2 | No difference compared with women with a BMI 18.5 to 24.9 kg/m2 |
| 30 to 35 | No difference compared with women with a BMI 18.5 to 24.9 kg/m2 | No difference compared with women with a BMI 18.5 to 24.9 kg/m2 |
| More than 35 | 67 per 1,000 (so this does not happen in about 933 pregnancies per 1,000). This is an average increase of 31 per 1,000 compared with women with a BMI 18.5 to 24.9 kg/m2 (so for about 969 pregnancies per 1,000, the outcome was the same) | 27 per 1,000 (so this does not happen in about 973 pregnancies per 1,000). This is an average increase of about 10 per 1,000 compared with women with a BMI 18.5 to 24.9 kg/m2 (so for about 990 pregnancies per 1,000, the outcome was the same) |
