Abstract: Prenatal nutrition can, by inducing variations in the in utero environment, influence the health and development of the unborn child. Inadequate nutritional intakes and suboptimal dietary quality can also pose a risk to the pregnant woman's health. The latter must cope with numerous physical, hormonal and psychological changes and adaptations that can turn her life upside down as well as influence her food choices. These changes, and the way women respond to them, can complexify the study of the associations between diet and maternal health outcomes. Moreover, the characterization of pregnant women's eating habits is often done incompletely, i.e. only intakes of specific nutrients or foods are measured, without taking into account the influencing factors. This thesis therefore examines dietary intakes and quality in a sample of pregnant women from Québec, in comparison with the recommendations and in association with sociodemographic, physiological and behavioral variables. The results generated by this thesis suggest that the eating habits of pregnant women from Québec are not optimal, both nutritionally and in terms of overall diet quality. Many physiological, sociodemographic and behavioral variables also seem to influence diet during pregnancy. These variables should be taken into consideration in the planning of nutritional interventions and the development of messages aimed to promote healthy eating habits among pregnant women.
