Higher Prevalence of Inadequate Vitamin D Intake in Toddlers Not Consuming a Vitamin D Supplement in Vancouver, Canada
Abstract
BACKGROUND: Vitamin D is required for growth and development. However, little is known about dietary intake and status during early childhood. OBJECTIVES: To determine vitamin D intake and status in a group of Canadian toddlers. METHODS: (25OHD) concentrations were quantified by liquid chromatography-tandem mass spectrometry. Blood sampling was dichotomized by season as winter (September to February) and summer (March to August). RESULTS: At age 1 y (n = 110) and 2 y (n = 86), the top food sources of vitamin D were dairy (73‒81%), fish (6.8‒14%), and eggs (4.1‒5.5%). Vitamin D-containing supplements were consumed by 43% of the toddlers at age 1 y and 48% at 2 y. Daily median (interquartile range) total vitamin D intakes were 7.9 (4.9‒13) μg at age 1 y and 7.2 (4.8‒14) μg at age 2 y. There was a higher prevalence of inadequate intake (
