1. Overall project description

1.1 Summary

Pregnancy and infancy are critical periods for nutritional programming of metabolic health. Epigenetic changes such as DNA methylation seem to have a crucial role linking early-life nutrition to metabolic health across the life course. The aim of NutriPROGRAM is to identify early-life nutrition-related factors and related epigenetic pathways leading to metabolic adaptations and disease across the life course. The objectives are to:

1) Harmonize and define the nutrition-related and metabolic factors and create new, integrated nutrition-related factors;

2) Identify differential DNA methylation related to maternal and infant nutrition-related factors and to susequent risk factors for metabolic health and disease across the life course;

3) Identify effects of preconception/early-pregnancy and infancy nutritional interventions on childhood DNA methylation and associations with metabolic health;

4) Study cause-and-effect relationships of DNa methylation in the associations of early-life nutrition-related factors and later metabolic health;

5) Characterize molecular mechanisms through which nutrition-related DNA methylation changes lead to developmental adaptations.

In the first 11 months of the project, NutriPROGRAM partners have established an inventory of available maternal and infant nutrition-related factors, which is now being used as a basis for harmonized analyses. Current work focuses on pregnancy vitamin B12 levels, glycemic index and load, and Mediterranean diet in related to DNA methylation. So far, NutriPROGRAM partners have found that DNA methylation levels at over 900 sites in cord blood are related to birth weight. In a further study, we did not find associations of newborn and childhood DNA methylation with liver fat fraction at school age. Work is ongoing on multiple epigenome-wide analyses examining associations of maternal and infant dietary exposures and childhood DNA methylation, as well as on associations of DNA methylation with childhood and adolescence cardiometabolic outcomes.

We expect that NutriPROGRAM will:

1) Create a set of harmonised and integrated nutrition-related factors that can be used by scientists studying the relationships between nutrition and health;

2) Lead to a better understanding of the role of DNA methylation in the pathways underlying the relation of early-life nutrition and metabolic health;

3) Lead to a better understanding of causality and modification of DNA methylation in these pathways. This will be a starting point for prevention of obesity, blood lipid disorders and type 2 diabetes;

4) Contribute to the development of methods to help identify the most promising findings from DNA methylation studies for further research;

5) Form a sustainable, international network of researchers on early-life nutrition, epigenetics and long-term metabolic outcomes that will lay the foundation for further research in this area for many years to come.



1.2 Highlights

Much of the core work in NutriPROGRAM is still ongoing. We describe here two finalized projects.

Project 1: Associations of DNA methylation with birth weight

Birthweight is associated with health outcomes across the life course. DNA methylation may be an underlying mechanism. In a large meta-analysis of epigenome-wide association studies of 8,825 neonates from 24 birth cohorts, including three NutriPROGRAM partners, in collaboration with the Pregnancy And Childhood Epigenetics Consortium, we found that DNA methylation in neonatal blood is associated with birthweight at 914 sites. The difference in birthweight ranged from -183 to 178 grams per 10% increase in methylation. Birthweight-related DNA methylation sites partly overlapped with some DNA methylation sites that were previously reported to be related to maternal smoking and to maternal body mass index in pregnancy, but not with those related to folate levels in pregnancy. Whether these associations are causal or explained by other factors influencing DNA methylation requires further research.

Project 2: Newborn and childhood differential DNA methylation and liver fat in school-age children.

Non-alcoholic fatty liver disease is the most common chronic liver disease in children in western countries. Adverse early-life exposures are associated with higher liver fat percentages in children. Differential DNA methylation may underlie these associations. We aimed to identify differential DNA methylation in newborns and children associated with liver fat accumulation in childhood. We also examined whether DNA methylation at 22 cytosine-phosphate-guanine sites (CpGs) associated with adult non-alcoholic fatty liver disease is associated with liver fat in children. Within the population-based prospective Generation R Study, we analyzed epigenome-wide DNA methylation data of 785 newborns and 344 10-year-old children in relation to liver fat fraction at 10 years, measured by Magnetic Resonance Imaging. No single CpGs and no differentially methylated regions were associated with liver fat accumulation. None of the 22 known adult CpGs were associated with liver fat in children. We conclude that DNA methylation at birth and in childhood was not associated with liver fat accumulation in 10-year-old children in this study. This may be due to modest sample sizes or DNA methylation changes being a consequence rather than a determinant of liver fat.
