Table 3.
Frequencies (N (%)) of pregnant women with TSH above the trimester specific cut-off in the total sample and delineated by CM status.
| Total sample | CM− | CM+ | |
|---|---|---|---|
| 1st trimester (TSH > 2.5 mU/l), N=94 | 18 (19.1) | 10 (15.2) | 8 (28.6) |
| 2nd trimester (TSH > 3.0 mU/l), N=101 | 12 (11.9) | 5 (6.8) | 7 (25.0) |
| 3rd trimester (TSH > 3.0 mU/l), N=99 | 12 (12.1) | 6 (8.3) | 6 (22.2) |
| Overall (TSH > trimester-specific cut-off in each trimester), N=90 | 8 (8.9) | 3 (4.6) | 5 (20.0) |
Note. CM = childhood maltreatment; TSH = thyroid-stimulating hormone. Trimester-specific reference ranges recommended by the American Thyroid Association and the Endocrine Society were applied.
