By analysing data from the Norwegian Mother and Child Cohort Study, and merging the dataset with data from the Norwegian Medical Birth Registry, we wish to examine if pre-pregnancy diet predicts child neonatal outcomes and outcomes related to maternal and child health differently than diet during pregnancy.
In addition, the study will explore whether an effect is modified by factors such as socioeconomic status and maternal weight status.
Hypotheses: 1) Pre-pregnancy diet is differently associated with maternal and child health compared to diet during pregnancy. 2) Socioeconomic differences exist in the association between preconception diet and health-related aspects of maternal and child health.
Non-communicable diseases (NCDs) account for 85-90% of the burden of disease in Norway, with poor diet as a leading cause, and with a clear gradient in diet quality and disease burden across socioeconomic groups. Nutrition in the first 1000 days of life plays a vital role in the causes of disease. Emerging evidence indicates that the nutritional status of parents at conception, and even before, influences the lifelong physical and mental health of their future children. Worldwide action is called for in translating this knowledge into public health benefits.
PRECONDIET will expand and generate new knowledge on the importance of preconception diet for health in the next generation.
