    Abstract:
    IMPORTANCE: Consumption of energy drinks has increased drastically in recent years, particularly among young people. It is unknown whether intake of energy drinks is associated with health during pregnancy. OBJECTIVE: To examine associations of energy drink intake before and during pregnancy with risk of adverse pregnancy outcomes (APOs). DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study included data from women enrolled in the Nurses' Health Study 3 (NHS3) between June 1, 2010, and September 27, 2021, and the Growing Up Today Study (GUTS) who reported 1 or more singleton pregnancy from January 1, 2011, to June 1, 2019. Data were analyzed from October 1, 2021, to September 28, 2023. EXPOSURE: Intake of energy drinks, assessed by food frequency questionnaire. MAIN OUTCOMES AND MEASURES: The main outcomes were self-reported APOs, including pregnancy loss, gestational diabetes, gestational hypertension, preeclampsia, or preterm birth, and a composite APO, defined as development of any of the APOs. Risk of APOs was compared between consumers and nonconsumers of energy drinks. RESULTS: This study included 7304 pregnancies in 4736 participants with information on prepregnancy energy drink intake and 4559 pregnancies in 4559 participants with information on energy drink intake during pregnancy. There were 1691 GUTS participants (mean [SD] age, 25.7 [2.9] years) and 3045 NHS3 participants (mean [SD] age, 30.2 [4.1] years). At baseline, 230 GUTS participants (14%) and 283 NHS3 participants (9%) reported any intake of energy drinks. While no associations were found for pregnancy loss (odds ratio [OR], 0.89; 95% CI, 0.71-1.11), preterm birth (OR, 1.07; 95% CI, 0.71-1.61), gestational diabetes (OR, 0.89; 95% CI, 0.58-1.35), preeclampsia (OR, 0.73; 95% CI, 0.41-1.30), or the composite APO (OR, 1.05; 95% CI, 0.87-1.26), prepregnancy energy drink use was associated with a higher risk of gestational hypertension (OR, 1.60; 95% CI, 1.12-2.29). A significant interaction was found between age and energy drink intake in relation to hypertensive disorders (P = .02 for interaction for gestational hypertension; P = .04 for interaction for any hypertensive disorders), with stronger associations for participants above the median age. No associations of energy drink intake during pregnancy with any of the APOs were found in NHS3 (eg, any APO: OR, 0.86; 95% CI, 0.41-1.79). CONCLUSIONS AND RELEVANCE: In this study, energy drink intake before pregnancy was associated with an elevated risk of gestational hypertension. Given the low prevalence of energy drink intake and low consumption levels among users, the results should be interpreted cautiously.
