Article Synopsis
- * The study highlights a significant discrepancy between dietary guidelines and actual food consumption in Norway, with over 60% of calories coming from imported sources.
- * Transitioning to more sustainable diets requires changing eating habits, focusing on local resources, and ensuring good animal welfare as key components of a sustainable food system.
Nutrient requirements vary across the reproductive cycle, but research on changes in nutritional intake and quality from pregnancy to beyond the lactation period is limited. Thus, we aimed to study nutritional intake and quality changes, among Swedish pregnant participants from late pregnancy to 18 months postpartum and to study the determinants of nutritional quality changes. Participants ( = 72) were studied longitudinally from the third trimester of pregnancy and postpartum (2 weeks 4, 12, and 18 months postpartum).

- The study explores the link between maternal vitamin D levels during pregnancy and children's body mass index (BMI) and risk of overweight at age 5.
- It uses data from two cohorts: the Norwegian Mother, Father and Child Cohort Study and the Swedish GraviD study, analyzing maternal vitamin D and children's BMI through regression models.
- Findings suggest that low maternal vitamin D (below 30 nmol/L) is associated with lower BMI in children, especially among mothers who are overweight or obese, but does not significantly affect the risk of childhood overweight.
Article Synopsis
- A significant number of pregnant women in Norway have insufficient vitamin D levels, prompting this study to assess their vitamin D intake from diet and supplements, as well as factors affecting their vitamin D status.* -
- The research involved nearly 3,000 pregnant women from the Norwegian Environmental Biobank, utilizing food frequency questionnaires and blood tests to evaluate vitamin D intake and 25OHD concentrations.* -
- Findings revealed that 61% of participants did not meet the recommended vitamin D intake, with higher levels linked to factors like season, supplement use, and lifestyle choices, indicating the need for improved vitamin D intake strategies during pregnancy.*
Background: Early childhood growth can affect the child's health status later in life. Maternal vitamin D status has been suggested to affect early childhood growth. However, there is a lack of studies investigating the role of maternal vitamin D status on growth trajectories during infancy.

Methods: Data from the Swedish prospective cohort GraviD, 2125 pregnant women, were randomly split in halves; one for developing the screening tool, and one for validation. Risk factors of vitamin D deficiency (serum 25-hydroxyvitamin D < 30 nmol/L) were identified using logistic regression analyses and odds ratios were translated into scores.
Background: The relationship between maternal vitamin D status in pregnancy and the development of atopic diseases in the offspring has been frequently studied, but with contradictory results. Previous studies have found an inverse relation between maternal vitamin D in pregnancy and the risk of atopic diseases in the child. In contrast, others have found a higher maternal 25OHD to be related to a higher risk of atopic diseases.

Design: Prospective population-based pregnancy cohort study.
Our objective was to validate vitamin D intake from a short vitamin D questionnaire (VDQ) and a longer online food frequency questionnaire (FFQ) against a food record and 25-hydroxyvitamin D (25OHD) as a biomarker of vitamin D status, among pregnant women in Sweden. The number of women included was 1125 with VDQ, FFQ and 25OHD, and of those, 64 also completed the food record. Median vitamin D intakes were 3.
