Introduction. Thyroid hormones play a fundamental role in the development of pregnancy and fetal growth. Untreated hypothyroidism is associated with an increased risk of preterm delivery, perinatal mortality, low birth weight, and alterations in the neuropsychomotor development of the neonate. In 2018, the Ministry of Public Health established a protocol for the diagnosis and management of hypothyroidism in pregnancy. Since there are no updated studies that use these new criteria, it is important to establish the frequency of thyroid pathologies in the population of Paraguayan pregnant women to improve timely treatment and reduce adverse outcomes. Objective. To determine the frequency of subclinical hypothyroidism in pregnant women treated in maternal and child services of the Ministry of Public Health. Materials and Methods. A cross-sectional, retrospective, descriptive study, with a non-probabilistic sampling, in a population of pregnant women who delivered in services belonging to the Ministry of Public Health network, between January, 1st 2017 and December 31, 2019 was carried out. The reports from the perinatal computer system were taken into account for data collection and subsequent analysis. Results. Of the 18845 patients studied, 170 presented diagnostic criteria for subclinical hypothyroidism, that represented a frequency of 0.902%. The average age of the patients was 24 years. Conclusion. The frequency of hypothyroidism in Paraguayan women justify expanding the coverage of detection and timely treatment to avoid congenital hypothyroidism and its adverse outcomes, preventable with adequate prenatal care.
