Breastfeeding and biomarkers of folate and cobalamin status in Norwegian infants: a cross-sectional study.

Folate and vitamin B (cobalamin) are essential for growth and development. This cross-sectional study aims to describe folate and vitamin B status according to infant age and breastfeeding practices in Norwegian infants. Infants aged 0-12 months ( = 125) were recruited through public health clinics.

Biotin: a scoping review for Nordic Nutrition Recommendations 2023.

Biotin is a water-soluble B-vitamin with key roles in metabolism and are found in most foods at low concentrations. Symptomatic biotin deficiency is rare, and few studies have investigated biotin requirements in relation to health outcomes. Data to support the setting of dietary reference values for biotin are limited.

Iodine Nutrition in Children ≤2 years of Age in Norway.

Background: As a component of the thyroid hormones (THs), iodine is vital for normal neurodevelopment during early life. However, both deficient and excess iodine may affect TH production, and data on iodine status in young children are scarce.

Objectives: To describe iodine nutrition (iodine status and intake) in children ≤2 y of age in Innlandet County (Norway) and to describe the associations with maternal iodine nutrition.

Inadequate Iodine Intake in Mothers of Young Children in Innlandet County, Norway.

Background: Iodine has an essential role in child growth and brain development. Thus, sufficient iodine intake is particularly important in women of childbearing age and lactating women.

Objectives: This cross-sectional study aimed to describe iodine intake in a large random sample of mothers of young children (aged ≤2 y) living in Innlandet County, Norway.

Vitamin B status in infancy and the effect of a vitamin B injection in infants with subclinical vitamin B deficiency: study protocol for a register-based randomised controlled trial.

Introduction: Vitamin B (cobalamin) is crucial for optimal child development and growth, yet deficiency is common worldwide. The aim of this study is twofold; (1) to describe vitamin B status and the status of other micronutrients in Norwegian infants, and (2) in a randomised controlled trial (RCT), investigate the effect of vitamin B supplementation on neurodevelopment in infants with subclinical vitamin B deficiency.

Methods And Analysis: Infant blood samples, collected at public healthcare clinics, are analysed for plasma cobalamin levels.

Social determinants and changes in energy drink consumption among adolescents in Norway, 2017-2019: a cross-sectional study.

Objectives: To describe the social determinants and development in energy drink consumption among Norwegian adolescents in 2017, 2018 and 2019.

Design: Cross-sectional, online, annual, nationwide surveys (Ungdata).

Setting: Responses collected online from January 2017 to December 2019.

Adequate Urinary Iodine Concentration among Infants in the Inland Area of Norway.

Considering the importance of iodine to support optimal growth and neurological development of the brain and central nervous system, this study aimed to assess and evaluate iodine status in Norwegian infants. We collected data on dietary intake of iodine, iodine knowledge in mothers, and assessed iodine concentration in mother's breast milk and in infant's urine in a cross-sectional study at two public healthcare clinics in the inland area of Norway. In the 130 mother-infant pairs, the estimated infant 24-h median iodine intake was 50 (IQR 31, 78) µg/day.

Biomarkers and Fatty Fish Intake: A Randomized Controlled Trial in Norwegian Preschool Children.

Background: Biomarkers such as omega-3 (n-3) PUFAs, urinary iodine concentration (UIC), 1-methylhistidine (1-MH), and trimethylamine N-oxide (TMAO) have been associated with fish intake in observational studies, but data from children in randomized controlled trials are limited.

Objectives: The objective of this exploratory analysis was to investigate the effects of fatty fish intake compared with meat intake on various biomarkers in preschool children.

Methods: We randomly allocated (1:1) 232 children, aged 4 to 6 y, from 13 kindergartens.

Dietary Intake and Biomarkers of Folate and Cobalamin Status in Norwegian Preschool Children: The FINS-KIDS Study.

Background: Folate and cobalamin (vitamin B-12) are essential for growth and development. However, few population-based studies have investigated B-vitamin status in children.

Objectives: This study aimed to assess biomarkers of folate and vitamin B-12 status and to explore their dietary determinants in healthy Norwegian children.

Mild to Moderate Iodine Deficiency and Inadequate Iodine Intake in Lactating Women in the Inland Area of Norway.

Breastfed infants are dependent on an adequate supply of iodine in human milk for the production of thyroid hormones, necessary for development of the brain. Despite the importance of iodine for infant health, data on Norwegian lactating women are scarce. We measured iodine intake and evaluated iodine status and iodine knowledge among lactating women.

The Reliability of Iodine Concentration in Diaper-Retrieved Infant Urine Using Urine Collection Pads, and in Their Mothers' Breastmilk.

Mild to moderate iodine deficiency is common among women of childbearing age. Data on iodine status in infants are sparse, partly due to the challenges in collecting urine. Urinary iodine concentration (UIC) is considered a good marker for recent dietary iodine intake and status in populations.
