Area of Science:

  • Environmental Health
  • Computational Toxicology
  • Maternal-Child Health

Background:

  • Lead exposure is a significant global health burden, particularly in developing countries.
  • Maternal blood lead levels (BLL) are a primary pathway for fetal lead exposure.
  • Current BLL monitoring is costly, time-consuming, and inaccessible, necessitating alternative screening methods.

Purpose of the Study:

  • To develop a computational model for predicting maternal blood lead levels using sociodemographic features.
  • To establish a cost-effective and accessible screening tool for lead toxicity in pregnant women.
  • To identify key sociodemographic factors influencing maternal lead exposure.

Main Methods:

  • A computational model framework was designed to predict lead toxicity.
  • Maternal data, including sociodemographic features and blood samples, were collected and analyzed.
  • Machine learning algorithms (kNN, DT, NN) were employed, with feature selection using the Boruta algorithm.

Main Results:

  • A 12-feature set identified by the Boruta algorithm yielded optimal prediction results.
  • The developed models demonstrated predictive accuracy, with kNN achieving 76.84%, DT 74.70%, and NN 73.99%.
  • The model effectively utilizes questionnaire-based sociodemographic information for initial lead level assessment.

Conclusions:

  • The prediction model can enhance point-of-care diagnostics, reducing costs and risks associated with lead toxicity.
  • The methodology holds potential for integration into routine screening processes for pregnant women.
  • Early identification and intervention can mitigate maternal lead exposure, thereby reducing fetal and infant lead burden.
