Comparison of variables between the patient with bipolar affective disorder and control patients.
| Variable | Bipolar patient. | Means ± S.D. N = 3 |
| Age/yrs | 25 | 29 ± 9 |
| Height/cm | 173.5 | 164.8 ± 7.2 |
| BMI | 22 | 26.8 ± 2.3 |
| Weight Gain/Kg | 6.9 | 6.5 ± 1.0 |
| 13 weeks Systolic/mmHg | 100 | 103 ± 15 |
| 22 weeks Systolic/mmHg | 100 | 120 ± 10 |
| 36 weeks Systolic/mmHg | 110 | 110 ± 10 |
| 13 weeks Diastolic/mmHg | 60 | 63 ± 6 |
| 22 weeks Diastolic/mmHg | 60 | 73 ± 6 |
| 36 weeks Diastolic/mmHg | 80 | 77 ± 15 |
| 1st trimester Hb (g/dl) | 11.4 | 14.2 ± 3.7 |
| 2nd trimester Hb (g/dl) | 11.4 | 11.4 ± 1.1 |
| 3rd trimester Hb (g/dl) | 11.9 | 11.2 ± 0.3 |
| Parity | 2 | 2 ± 2 |
| Gestational age (days) | 272 | 273 ± 2 |
| Birth weight (g) | 2500 | 3573 ± 133 |
| Placental weight (g) | 350 | 607 ± 51 |
| Crown Heel length (cm) | 51 | 48.5 ± 3.0 |
| Head Circumference (cm) | 32 | 33.6 ± 0.7 |
| Ponderal index (g/cm3) | 18.8 | 32 ± 7.1 |
| Head Circumference:length ratio | 62.7 | 69.5 ± 3.0 |
| Placenta: Birth weight ratio | 14 | 17 ± 0.8 |
The patient with bipolar affective disorder had lower infant birth weight and lower placental weight, resulting in lower ponderal index and placenta:birthweight ratio.
