ABSTRACT
Background:
The use of organophosphorus pesticides such as malathion is common in agricultural and public health activities in Latin America. However, there is a significant gap in exposure monitoring and regulation, especially in biologically vulnerable populations such as pregnant women and newborns.
Objective:
To map and synthesize the available scientific evidence on malathion exposure and its effects on the health of the maternal-fetal dyad in Mexico and Latin America.
Methods:
A scoping review will be conducted following the Joanna Briggs Institute guidelines and the PRISMA-ScR framework. The population of interest includes pregnant women and newborns exposed to malathion in the Latin American context, under the Population, Concept, and Context (PCC) scheme. An exhaustive search will be performed in databases such as PubMed, Scopus, Web of Science, SciELO, and grey literature. Data selection and extraction will be carried out by four independent reviewers.
Results:
A narrative synthesis will be presented characterizing exposure assessment methods, reported health outcomes, and geographical and methodological gaps in regional research.
Conclusions:
The findings will aim to inform decision-makers to strengthen pesticide regulation policies and protect public health in the region.
