Objectives: Gestational hypothyroidism is associated with obstetric complications and disturbances in the offspring development; however, it remains easy to treat. The objective of the study was to describe thyroid-stimulating hormone (TSH) levels in pregnant women and analyze their association with pregnancy course and outcome. Design: This national, observational, retrospective study analyzed data on Lebanese pregnant women visiting their obstetrician as part of their routine follow up. Participants, Setting and Methods: Enrolled subjects were all pregnant women who visited the obstetrics clinic from 01 September 2017 until 31 August 2018, as part of their routine follow up and have a TSH level record. In 2020, during their routine follow-up visit, the participants signed an informed consent to allow the investigator to access the data retrospectively and enter them into his database. Relevant participant characteristics and outcome data were collected from clinic files of the private clinic of Dr Abi Tayeh, at the Department of Obstetrics and Gynecology, H?tel-Dieu de France University Hospital, Beirut, Lebanon. Results: A total of 419 women were enrolled, 11.5% of them reported at least one comorbidity prior to pregnancy, most often the antiphospholipid syndrome, followed by thrombophilia and hypothyroidism. At least one complication was reported for 18.4% of participants. Around 87.6% of participants delivered a full-term baby with normal birth weight for most. The average TSH value for all participants was within the normal range at all time-points. Highest TSH values were recorded during the first trimester. As treatment was immediately initiated in women with abnormal TSH levels, no correlation was observed between TSH levels and pregnancy outcomes or pregnancy complications at any time-point. Conclusions: This study highlights satisfactory routine practice in the management of thyroid disorders in pregnancy and underscores the need for routine TSH screening for all pregnant women.
