Background: Thyroid dysfunction during pregnancy is associated with adverse outcomes for both mother and fetus. The present meta-analysis was conducted to evaluate thyroid dysfunction in Iranian pregnant women. Methods: We registered this review at PROSPERO (registration number: CRD42020166655). The research steps in this systematic review and meta-analysis were performed according to the MOOSE protocol, and finally, reports were provided based on the PRISMA guidelines. The literature search was performed in October 2019 using the international online databases, including Web of Science, Ovid, Science Direct, Scopus, EMBASE, PubMed/Medline, Cochrane Library, EBSCO, CINAHL, Google Scholar as well as national databases were reviewed. Data were extracted after applying the inclusion and exclusion criteria and qualitative evaluation of the studies. I 2 index and Q test were used to assess differences in studies. All analyses were performed using Comprehensive Meta-Analysis Software. Pvalue less than 0.05 was considered statistically significant. We identified 1261 potential articles from the databases, and 426 articles remained after removing the duplicate and unrelated studies. After evaluating the full text, 52 articles were removed. Results: Finally, 19 eligible studies including 17,670 pregnant women included for meta-analysis. The prevalence of thyroid dysfunction in Iranian pregnant women was 18.10% (95%CI: 13.89-23.25). The prevalence of hypothyroidism, clinical hypothyroidism, and subclinical hypothyroidism in Iranian pregnant women was respectively estimated to be 13.01% (95%CI: 9.15-18.17), 1.35% (95%CI: 0.97-1.86) and 11.90% (95%CI: 7.40-18.57). The prevalence of hyperthyroidism, clinical hyperthyroidism, and subclinical hyperthyroidism in Iranian pregnant women was respectively estimated to be 3.31% (95%CI: 1.62-6.61), 1.06% (95%CI: 0.61-1.84) and 2.56% (95%CI: 0.90-7.05). The prevalence of anti-thyroperoxidase antibody was estimated to be 11.68% (95%CI: 7.92-16.89). Conclusion: The results of this meta-analysis showed a high prevalence of thyroid disorders, especially hypothyroidism. The decision to recommend thyroid screening during pregnancy for all women is still under debate, because the positive effects of treatment on pregnancy outcomes must be ensured. On the other hand, evidence about the effect of thyroid screening and treatment of thyroid disorders on pregnancy outcomes is still insufficient. Nevertheless, a large percentage of general practitioners, obstetricians and gynecologists perform screening procedures in Iran.

“…Globally, thirty-two million four hundred thousand (38.2%) pregnant women were found to anemic [3]. A systematic review conducted in Iran showed that the prevalence of anemia was 17.9% [4]. Its burden became worth in developing countries which was 48.7% in South East Asia and 46.3% in Africa [3].…”

Background Even though anemia was highly targeted in different global strategies, many pregnant and/or lactating women and children were suffering from it and its complications. Besides this, prior trend analysis has not been conducted among pregnant and/or lactating women in Ethiopia. Therefore, this study aimed to assess the trend and determinants of anemia change among pregnant and/or lactating women in Ethiopia. Methods The study utilized two consecutive Ethiopia Demographic and Health Survey (EDHS) datasets. A total of 6,106 and 5,641 pregnant and/or lactating women in 2011 and 2016 survey respectively were included in the analysis. The data were analyzed by using Stata version 14.0. Logit based decomposition analysis was done to identify contributing factors for anemia change and statistical significance was determined by using P-value. Results The trend of anemia was increased from 19% in 2011 to 29% in 2016 EDHS. The analysis revealed that, 8% of the overall change in anemia was because of the change in women’s composition. Changes in the composition of pregnant and/or lactating women according to region, economic status and tobacco and/or cigarette use were the major sources of the change. Greater than 90% of the increase in anemia was due to differences in the coefficient. Mostly, the change in behaviors of the Amhara population, those who had a history of terminated pregnancy and use tobacco and/or cigarette were the sources of the change. Conclusions Anemia among pregnant and/or lactating women was increased against government interventions over the last half-decade in Ethiopia. Programmatic interventions targeting Somali and Dire Dawa regions are still needed to decrease anemia.

“…There are many physiological effects of pregnancy on thyroid gland function. 8 The countries where iodine is adequate, the thyroid gland's size increases by 10% during pregnancy, whereas it may increase to a greater extent in countries where there is a deficiency of iodine. 9 during pregnancy, deficiency of thyroid hormone and requirement of iodine both exacerbates by 50% approximately as part of physiology.…”

Introductions: Pregnancy is a period in which there are physical and hormonal changes for the development of the fetus and essentials nutrients supply and the preparation of the maternal organism for birth and lactation. There is a paucity of data on the endocrine function of the thyroid gland in pregnancy in Saudi Arabia. The purpose of this study was to assess the impact of the endocrine function of thyroid gland in pregnancy and current techniques for its management. Methods: In this systematic review and meta-analysis, PRISMA (preferred reporting items for systematic review and meta-analysis) was used. Cochrane handbook guidelines were used for all aspects of this study. It includes published and unpublished studies with different study designs. Such studies were found from databases which include Google Scholar, Embase Medline, PsycINFO, Google, and Cochrane library up to the last week of January 2022 without any language restriction and identified all RCTs related to the endocrine function of the thyroid gland and its impact on pregnancy. Results: All RCTs connected to the endocrine function of the thyroid gland and its impact on pregnancy were found using a total of 304 articles from the electronic database Google Scholar, PubMed, Embase, PsycINFO, and the Cochrane Library, which were searched without any language restrictions. ''Endocrine'', ''Endocrine function'', ''Thyroid'', ''TSH’’, ‘‘T3’’, ‘‘T4’’, ‘‘hormones’’ and ‘‘pregnancy’’ and ‘‘randomized controlled trial’’ were some of the search terms we utilized. In addition, we searched references in a few journals to find more potentially relevant studies. Due to redundancy, 92 articles were excluded from the total of 304. A total of 107 articles were reviewed, with 77 rejected following a preliminary review. There were 30 full-text papers reviewed for eligibility, and 10 of them met the inclusion requirements, with all of the selected articles being of high quality. The parameters of the trials differed greatly in terms of treatment length and population investigated. All of the studies were nonrandomized and compared groups based on retrospective chart reviews. Out of 10 studies, three were from Iran, two from Saudi Arabia, one from the United States, one from Denmark, one from Ireland, one from Netherland, and one from Australia.
