Abstract: BACKGROUND: Air pollution is known to have many grave impacts on the health of individuals; over 80% of people living in urban areas are exposed to levels of air pollutants that exceed the limits set by the World Health Organization (WHO, 2016). Past studies have examined the association between air pollution exposure and development of gestational diabetes mellitus, but there is limited evidence of this association. OBJECTIVES: To review the literature, in order to explore existing studies that look at the association between exposure to PM2.5 or ozone and the development of gestational diabetes mellitus (GDM). METHODS: A structured literature review was conducted in the PubMed (Medline) database to investigate the research question. The keywords searched in the final strategy were "(Particulate matter OR ozone) AND gestational diabetes". Quantitative studies were included in the search, while studies with a focus on type 2 diabetes mellitus or smoking were excluded. RESULTS: The initial search strategy returned 18 results, with the final number of articles being narrowed down to 5. Only one study was able to confirm a positive association between the two variables under study. Three other studies showed an association between exposure to ozone or PM2.5 and GDM, but only under very specific conditions. The remaining study did not show an association between the variables under study. CONCLUSIONS: The literature does not show robust evidence of an association between ozone or PM2.5 and the development of GDM. Further research is needed in order to be able to draw more accurate conclusions.
