Abstract: Higher maternal body mass index (BMI) is associated with metabolic disturbances and pregnancy complications. We aimed to examine whether metabolic profiles in early pregnancy were associated with metabolic pregnancy complications in women with obesity (BMI ≥ 30 kg/m 2 ). Nested cohort study from a prospective longitudinal cohort ( n = 1031) of women who were healthy prior to pregnancy and gave birth at Oslo University Hospital from 2002–2008. The sample comprised 81 women with obesity. Metabolic pregnancy complications included gestational diabetes mellitus, gestational hypertension and preeclampsia. In plasma samples from gestational weeks 14–16, 91 metabolites were analyzed by nuclear magnetic resonance spectroscopy. We performed a principal component analysis to reduce the metabolic dimensions. Logistic regression models were fitted to estimate crude and adjusted odds ratios (ORs) of metabolic pregnancy complications. Twenty-four out of 81 women developed metabolic pregnancy complications (gestational hypertension, preeclampsia, and/or gestational diabetes). Two of five principal components (80 % explained variance) were significantly associated with metabolic pregnancy complications. The ratio of monounsaturated to total fatty acids increased the risk of metabolic pregnancy complications (OR 2.09, 95 % confidence interval [CI] 1.25–3.75), while the ratio of polyunsaturated to monounsaturated fatty acids decreased the risk (OR 0.54, 95 % CI 0.30–0.89). The ratio of omega-3 to total fatty acids (OR 0.59, 95 % CI 0.34–0.98) and the ratio of docosahexaenoic acid to total fatty acids (OR 0.57, 95 % CI 0.31–0.97) also decreased the risk of metabolic pregnancy complications. Metabolic profile in early pregnancy was associated with risk of metabolic pregnancy complications in women with obesity. We observed the strongest associations between fatty acid composition and metabolic pregnancy complications. Graphcal abstract created with BioRender.com.
