Resumen:
Background: Preeclampsia is a pregnancy-specific condition affecting 2%-8% of pregnant females and a leading cause of maternal and perinatal morbimortality. High ultraprocessed food (UPF) consumption has been associated with the development of noncommunicable chronic diseases, but evidence on pregnancy outcomes is scarce. Objectives: To study the association of maternal UPF consumption and the risk of preeclampsia. Methods: This study is a secondary analysis of the IMPACT BCN, a randomized clinical trial including 1221 pregnant females at high risk for small for gestational age newborns, conducted in Barcelona, Spain. Among these, 812 participants with complete dietary data at 2 timepoints during pregnancy (between weeks 19-23 of gestation and weeks 34-36 of gestation) were included in this analysis and classified into tertiles of change in UPF consumption during pregnancy. Dietary UPF consumption was assessed using NOVA classification with a validated 151-item food frequency questionnaire. Preeclampsia was defined as high blood pressure plus targeted organ involvement. Analyses were performed using logistic regression models adjusted for potential confounding factors. Results: Associations between change of UFP consumption during pregnancy and overall preeclampsia were observed across tertiles [odds ratio (OR)T3 compared with T1 : 2.29; 95% confidence interval (CI): 1.06, 4.97, P-trend 0.026], but not when UPF change was modeled as a continuous variable [OR:1.04; 95% CI: 0.95, 1.14]. Among UPF subclasses, pre-prepared dishes were significantly associated with preeclampsia risk [ORT3 compared with T1 : 2.36; 95% CI: 1.09, 5.12]. Conclusions: In a high-risk population, a higher change in dietary intake of UPF consumption from the second to third trimester of pregnancy was associated with a higher risk of preeclampsia. This trial was registered at clinicaltrials.gov as NCT03166332.
