Interventions carried out during pregnancy could thus be missing the mark in maximizing intervention health benefit.</p> <p><strong>Objective</strong>: To investigate whether pre-pregnancy and early pregnancy dietary behavior as reported at inclusion into the Norwegian Fit for Delivery (NFFD) trial was associated with maternal and neonatal outcomes irrespective of subsequent randomization assignment.</p> <p><strong>Design</strong>: The study is a post-hoc observational analysis of data from a randomized controlled lifestyle intervention. We constructed two diet scores from participant responses to a 43-item questionnaire that addresseddietary behavior in retrospect (pre-pregnancy diet score) and dietary behavior at inclusion (early pregnancy diet score), respectively. The diet scores ranged from 0 to 10, with higher score reflecting healthier dietary behavior. Associations between diet scores and maternal and neonatal health outcomes were estimated in multivariate logistic regression models.</p> <p><strong>Results</strong>: A total of 591 women were eligible for analysis. A one-point increase in pre-pregnancy diet score<br>was associated with lower odds of excessive gestational weight gain (GWG) (odds ratio [OR]adj: 0.92; 95%<br>confidence interval [CI]: 0.84–1.00, p = 0.050), preterm delivery (ORadj: 0.81; 95% CI: 0.68–0.97, p = 0.019),<br>and birthweight ≥ 4,000 g (ORadj: 0.88; 95% CI: 0.78–0.99, p = 0.038). A one-point increase in early pregnancy<br>diet score was associated with lower odds of excessive GWG (ORadj: 0.88; 95% CI: 0.79–0.97, p = 0.009), preterm<br>delivery (ORadj: 0.82; 95% CI: 0.67–0.99, p = 0.038), and preeclampsia (ORadj: 0.78; 95% CI: 0.62–0.99,<br>p = 0.038).</p> <p><strong>Discussion</strong>: Higher diet score either pre-pregnancy or in early pregnancy was protectively associated with excessive GWG and preterm delivery, whereas the protective association with high birthweight was confined to<br>pre-pregnancy diet and with preeclampsia to early pregnancy diet.</p> <p><strong>Conclusions</strong>: Both pre-pregnancy and early pregnancy dietary behavior was associated with important maternal and neonatal health outcomes in the NFFD dataset.</p&gt;}, journal={Food & Nutrition Research}, author={Hillesund Elisabet R. and Bere Elling and Sagedal Linda R. and Vistad Ingvild and Seiler Hilde L. and Torstveit Monica K. and Øverby Nina C.}, year={2018}, month={Aug.} }
