  • Infant Diet Is Associated With BMI Later in Childhood

    Open AccessJenny Jonsdottir, Birna Thorisdottir et al.ARTICLEMaternal and Child Nutrition2026

    Few studies have explored associations between indexes incorporating both breastfeeding and complementary feeding and future risk of overweight/obesity. The aim of this study was to explore associations between a previously developed Infant Diet Score (IDS; higher score reflecting better alignment with breastfeeding and complementary feeding guidelines in the first year of life), and the risk of overweight and/or obesity in childhood. Nutrition a…

  • An Infant Diet Score Based on Health Records Is Associated With BMI

    Open AccessJenny Jonsdottir, Birna Thorisdottir et al.ARTICLEMaternal and Child Nutrition2025

    Nationwide health records provide innovative research opportunities. The aim of this study was to describe infant feeding in the first year of life amongst all infants in Iceland born January 2009 to June 2015 (N = 30,623), explore the feasibility of creating a composite infant diet score (IDS) for the period 0-12 months in a subset of infants with complete records from routine nutrition monitoring (n = 12,848), and examine its associations with …

  • A repeated cross‐sectional analysis of the Icelandic baby food market surveyed in 2016, 2019 and 2021

    Open AccessBirna Thorisdottir, Tinna Odinsdottir et al.ARTICLEMaternal and Child Nutrition2023

    World Health Organisation (WHO) has stated that countries need to know their local commercial baby food (CBF) market. Data from other countries suggest rapid changes in CBF options, highlighting the need for repeated analysis. In that context, this repeated cross-sectional study analysed the options and nutrient quality of different CBF types available in Iceland in years 2016, 2019 and 2021. Data was gathered on formulas, porridge flours, foods …

  • Iodine status of breastfed infants and their mothers' breast milk iodine concentration

    Open AccessErna Petersen, Birna Thorisdottir et al.ARTICLEMaternal and Child Nutrition2020

    Iodine is an essential nutrient for growth and development during infancy. Data on iodine status of exclusively (EBF) and partially breastfed (PBF) infants as well as breast milk iodine concentration (BMIC) are scarce. We aimed to assess (a) infant iodine nutrition at the age of 5.5 months by measuring urinary iodine concentration (UIC) in EBF (n = 32) and PBF (n = 28) infants and (b) mothers' breast milk iodine concentration (n = 57). Sixty moth…
