The pooled prevalence of hypothyroidism among pregnant women was 17% [95% confidence interval (CI): 14%, 19%] with subclinical hypothyroidism at 15% (95% CI: 12%, 18%) and overt hypothyroidism at 3% (95% CI: 3%, 4%). In women with subclinical hypothyroidism, the pooled prevalence of adverse maternal outcomes was 9% (95% CI: 6%, 11%), while the prevalence of adverse foetal outcomes was 11% (95% CI: 9%, 14%). The pooled prevalence was 18% for preterm birth (95% CI: 11%, 25%), 17% for low birth weight (95% CI: 10%, 25%), 7% for intrauterine death (95% CI: 2, 14%), and 2% for stillbirth (95% CI: 0, 4%). Among women with overt hypothyroidism, the prevalence of adverse maternal and foetal outcomes was 12% (95% CI: 10%, 15%) and 14% (95% CI: 11%, 17%), respectively. The pooled prevalence was 22% for low birth weight (95% CI: 13%, 31%), 16% for preterm birth (95% CI: 9%, 24%), 16% for intrauterine death (95% CI: 7%, 27%), and 6% for stillbirth (95% CI: 1%, 13%). Most studies used trimester-specific TSH cut-offs based on the American Thyroid Association guidelines. One fourth (n=15) of the 60 studies applied alternative thresholds, with upper limits for normal TSH varying from 4.0-10.0 mIU\/L.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interpretation and conclusions<\/jats:title>\n                    <jats:p>The rising burden and adverse consequences of hypothyroidism in pregnancy demand urgent attention.
