Our study focuses on the impact of the pesticide DDT on maternal and child health, specifically in relation to obesity and breast cancer. The objective is to investigate the interdependence of obesity and breast cancer resulting from DDT exposure on a hormonal level, particularly estrogen, and to understand the association between DDT exposure and maternal and child health. The methodology employs a meta-analysis approach, analyzing independent studies on DDT's impacts on obesity and breast cancer, and examining the correlation between maternal DDT exposure and obesity, as well as the impact of obesity on breast cancer gene mutations. The study population primarily consists of mothers and their newborn children from the United States, with a focus on the persistence of DDT in regions such as South America, Africa, and Asia. Additionally, rodent studies were analyzed to see the impacts of DDT on generational development and reproduction. The data analysis is drawn from primary sources of similar research studies published in journals or scholarly websites, with a focus on the reliability and validity of the data. The results indicate a significant association between DDT exposure and obesity, as well as an increased risk of breast cancer, particularly estrogen receptor-positive cancer, in both maternal and child health. The report suggests a correlation between DDT exposure and heightened susceptibility to transgenerational obesity and breast cancer. However, it emphasizes the imperative for additional research endeavors and regulatory initiatives aimed at exploring alternative solutions to DDT and comprehending its multigenerational ramifications regarding disease.
