Abstract
Background
Thyroid dysfunction ranks among the most prevalent endocrine disorders. This disorder during pregnancy has been linked to adverse effects on both the mother and the baby. However, there is a scarcity of data and inconsistent documentation regarding thyroid issues in pregnant women in low-income nations.
Objective
The aim of this systematic review and meta-analysis was to determine the general prevalence of thyroid disorders in pregnant women.
Methods
To identify relevant studies, a comprehensive search was conducted across Scopus, PubMed, Science Direct databases, and Google Scholar and repository registers from January 1, 2000 to December 31, 2023. Ten pertinent publications were chosen for the final meta-analysis. Relevant data was extracted using Microsoft Excel and analyzed using STATA software version 17, employing a random-effect model. Sensitivity analysis was conducted to evaluate each study's impact on the outcome, and Egger's test was utilized to detect publication bias. A trim-and-fill analysis was executed to adjust for bias in the effect estimate. Heterogeneity across studies was assessed using Cochran's Q statistic and I2 statistics. Subgroup analysis was carried by study design, country and publication year.
Results
In this systematic review and meta-analysis, the prevalence of thyroid dysfunction among 2538 pregnant women was 12.0 % (95 % CI: 8.00 %–17.00 %). To account for the significant heterogeneity observed, a random effect model was utilized. Specifically, the prevalence of hypothyroidism in pregnant women was determined to be 10.00 % (95 % CI: 4.00–16.00 %) with a high level of heterogeneity (I2 = 94.27 %, p < 0.001). Notably, the sensitivity analysis conducted did not reveal any substantial impact on the overall pooled prevalence of thyroid dysfunction.
Conclusion
The meta-analysis revealed a significantly higher rate of thyroid disorders among pregnant women compared to global estimates. To assess the effects of treating thyroid conditions on pregnancy outcomes and inform clinical decisions, it is recommended to implement cost-effective thyroid-stimulating hormone screening during pregnancy.
