    Dietary Inflammatory Index Is Differentially Associated With Cardiometabolic Health After Pregnancy on the Basis of Adverse Pregnancy Outcome Exposure
    (American Heart Association, 2024) Jancsura, McKenzie K.; Wirth, Michael D.; Helsabeck, Nathan P.; Mercer, Brian M.; Haas, David M.; Greenland, Philip; McNeil, Rebecca; Levine, Lisa D.; Silver, Robert M.; Yee, Lynn M.; Saade, George R.; Khan, Sadiya S.; Chung, Judith H.; Grobman, William A.; Obstetrics and Gynecology, School of Medicine
    Background: Inflammatory diets may influence risk of cardiovascular disease. Subsequent cardiovascular disease is also influenced by adverse pregnancy outcomes (APOs) such as preterm birth, small-for-gestational-age birth, gestational diabetes, and hypertensive disorders of pregnancy. However, the associations between inflammatory diet, APOs, and cardiometabolic health remain unclear. Methods and results: We used data from the nuMoM2b (Nulliparous Pregnancy Outcomes Study Monitoring Mothers-to-Be) HHS (Heart Health Study) to assess the relationship between dietary quality and cardiometabolic health. We calculated Energy-Adjusted Dietary Inflammatory Index scores representing the inflammatory burden in a person's diet. We used linear regression to determine the association between Energy-Adjusted Dietary Inflammatory Index score and cardiometabolic outcomes. We performed stratified analyses for outcomes with a significant interaction between Energy-Adjusted Dietary Inflammatory Index and APO. Data were available from 3249 participants at a median of 3.1 years after delivery. Higher Energy-Adjusted Dietary Inflammatory Index scores were associated with higher body mass index (B=0.29 kg/m2 [95% CI, 0.16-0.42]), waist circumference (0.66 cm [95% CI, 0.39-0.93]), diastolic blood pressure (0.26 mm Hg [95% CI, 0.09-0.44]), mean arterial pressure (0.23 mm Hg [95% CI, 0.06-0.40]), triglycerides (2.11 mg/dL [95% CI, 1.05-3.18]), creatinine (2.78 mg/dL [95% CI, 1.13-4.44]), insulin (exp[B]=1.04 [95% CI, 1.03-1.05]) and C-reactive protein (exp[B]=1.07 [95% CI, 1.04-1.10]), and lower high-density lipoprotein cholesterol (-0.41 mg/dL [95% CI, -0.66 to -0.37]) (all P<0.01). Significant interactions with APO (P<0.05) were identified for body mass index and waist circumference, with stratified analysis revealing stronger associations for individuals with APOs. Conclusions: A more proinflammatory diet was associated with worse cardiometabolic health measures, and these relationships differed by a person's APO history. Further investigation should establish how dietary modifications after pregnancy may potentially mitigate cardiovascular disease risk.
