there is no evidence that maternal levothyroxine therapy im-

proves this outcome. Targeted antenatal screening for thy-

roid function will miss a substantial percentage of women

with thyroid dysfunction. In children SCH (serum TSH con-

centration >5.5–10 mU/l) normalizes in >70% and persists in

the majority of the remaining patients over the subsequent

5 years, but rarely worsens. There is a lack of studies examin-

ing the impact of SCH on the neuropsychological develop-

ment of children under the age of 3 years. In older children,

the evidence for an association between SCH and impaired

neuropsychological development is inconsistent. Good qual-

ity studies examining the effect of treatment of SCH in chil-

dren are lacking. © 2014 European Thyroid Association

I ntroduction

S ubclinical hypothyroidism (SCH) in pregnancy is de-

fined by a serum thyroid-stimulating hormone (TSH)

concentration higher than the upper limit of the pregnan-

cy-related reference range associated with a normal se-

A bstract

T his guideline has been produced as the official statement

of the European Thyroid Association guideline committee.

Subclinical hypothyroidism (SCH) in pregnancy is defined as

a thyroid-stimulating hormone (TSH) level above the preg-

nancy-related reference range with a normal serum thyrox-

ine concentration. Isolated hypothyroxinaemia (defined as a

thyroxine level below the 2.5th centile of the pregnancy-re-

lated reference range with a normal TSH level) is also recog-

nized in pregnancy. In the majority of SCH the cause is auto-

immune thyroiditis but may also be due to iodine deficiency.

The cause of isolated hypothyroxinaemia is usually not ap-

parent, but iodine deficiency may be a factor. SCH and iso-

lated hypothyroxinaemia are both associated with adverse

obstetric outcomes. Levothyroxine therapy may ameliorate

some of these with SCH but not in isolated hypothyroxin-

aemia. SCH and isolated hypothyroxinaemia are both associ-

ated with neuro-intellectual impairment of the child, but
