| Body mass index (kg/m2): before pregnancy | −.10 | .30 |
| Leukocyte telomere lengthb (T/S ratio) | .76 | <.01 |
| White blood cell countb (μl) | −.03 | .75 |
| Glycosylated haemoglobinb (%) | −.07 | .48 |
| Mental component summary score of SF‐36 | .03 | .76 |
| Physical component summary score of SF‐36 | −.02 | .84 |
| Total energy intake (kcal/d) | .22 | .03 |
| Protein intake (% of total energy intake) | −.45 × 10−2 | .96 |
| Carbohydrate intake (% of total energy intake) | −.05 | .60 |

Note. T/S ratio = ratio of telomere repeat copy number to single‐gene copy number; SF = short‐form health survey; DFE = dietary folate equivalent.
