Bibliometric Analysis: Exploring Pregnant Women’s Cadmium (Cd) Exposure And Preeclampsia Over 69 Years

Abstract

Preeclampsia is a critical pregnancy complication characterized by hypertension and proteinuria after 20 weeks of gestation, significantly impacting maternal and fetal health. Beyond age and genetic factors, environmental exposure to heavy metals, particularly cadmium (Cd), has been associated with an increased risk of preeclampsia. This study employs bibliometric analysis to investigate trends in research on cadmium exposure and preeclampsia from 1955 to 2024. Using Scopus-indexed articles analyzed with VOSviewer and Tableau, this study identifies publication trends, key contributing countries, and thematic focuses in the field. Results highlight a notable increase in research since 2015, with the United States, China, and Mexico leading contributions. Keywords such as "Pregnancy AND Cadmium" and "Preeclampsia" reveal evolving themes linking environmental exposure to adverse pregnancy outcomes. This study underscores the importance of mitigating cadmium exposure to support maternal health and aligns with global efforts to achieve SDGs 3 (Health), 6 (Clean Water),11 (Sustainable Cities), and 12 (Responsible Consumption).
