Serum samples were collected in 10\u201320 weeks\u2019 gestation and used for targeted metabolomic assay measurement. The associations among pBMI, metabolites, and GDM were investigated using linear regression and logistic regression models. Mediation analysis was conducted to evaluate the mediating effect of individual metabolite and clustered latent variable (LV) on the association of pBMI with GDM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified eight metabolites significantly associated with both pBMI and GDM, which contained three organic acids, three acylcarnitines, and two fatty acids. Mediation analysis found five individual metabolites and two clustered LVs exhibited significant mediation effects in the association between pBMI and GDM risk. LV1 showed mediated proportions of 24.0%, which represented as organic acids and enriched in branched\u2010chain amino acid biosynthesis. LV2 showed mediated proportions of 19.1%, which represented as acylcarnitines and enriched in linoleic acid metabolism. Furthermore, we validated the mediating role of branched\u2010chain amino acids during the OGTT period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
