Summary
In Precondiet we use existing unique Norwegian health surveys linked with birth registry data to explore adolescent and pre-pregnancy diet in relation to maternal and child health outcomes. Dietary data from Young-HUNT at adolescent age have been explored.
Our first results from this study are out. In Young-HUNT1, there was evidence of associations between dietary choices, meal patterns, and neonatal outcomes. These findings were similar in the pooled analyses but were attenuated to the point of non-significance in the smaller Young-HUNT3 cohort.
Overall, energy-dense food products were associated with a small detrimental impact on some neonatal outcomes, whereas healthier food choices appeared protective. Our study suggests that there are causal links between consumption of healthy and unhealthy food and meal patterns in adolescence with neonatal outcomes for offspring some years later. The effects seen are small and will require even larger studies with more state-of-the-art dietary assessment to estimate these robustly.
A second paper estimating the associations of adolescent dietary patterns and meal habits with hypertensive disorders of pregnancy (HDP) and preterm birth are under consideration for publication.
