Abstract: Pregnancy has long been recognized as a determinant of the mother’s and infant’s future health. Among other factors, the mother's diet is known to have a great impact on many pregnancy-related outcomes. In fact, inadequate dietary intakes have often been associated with a high risk of developing adverse pregnancy outcomes, such as gestational diabetes. The evaluation of potential associations between diet and health variables may, however, be affected by an imprecise assessment of pregnant women’s actual dietary intakes. Multiple administrations of a 24-hour dietary recall have the potential to accurately assess the diet of pregnant women, but its traditional version is often criticized for the time it requires and the many biases induced by the presence of an interviewer. To overcome this problem, new standardized and fully automated food assessment methods have been developed. These were recognised as valid in the general population, however, their precision during pregnancy has not yet been fully assessed. This thesis assesses the validity of the R24W, a Web-based 24- hour dietary recall, among pregnant women. Eventually, this validation will allow to use this dietary assessment tool in future epidemiological studies as well as for the nutritional management of pregnant women in a clinical context.
